Cost of Data: Calculating the True Cost of Data Storage

1. Understanding the Importance of Data Storage Costs

Data is one of the most valuable assets in the modern world. It drives innovation, decision-making, and competitive advantage for businesses and organizations across various domains. However, data also comes with a cost. Storing, managing, and accessing data requires resources, infrastructure, and expertise that can have a significant impact on the bottom line. Therefore, it is essential to understand the true cost of data storage and how to optimize it for efficiency and performance.

There are several factors that influence the cost of data storage, such as:

- The type and volume of data: Different types of data have different storage requirements and characteristics. For example, structured data (such as relational databases) is usually easier to store, query, and analyze than unstructured data (such as images, videos, or text documents). Similarly, the volume of data affects the storage capacity, scalability, and redundancy needed to ensure availability and reliability.

- The storage medium and technology: Data can be stored on various mediums and technologies, such as hard disk drives (HDDs), solid state drives (SSDs), tapes, optical discs, cloud storage, or hybrid storage. Each of these options has its own advantages and disadvantages in terms of cost, performance, durability, and security. For example, HDDs are cheaper and offer higher capacity than SSDs, but they are also slower, more prone to failure, and consume more power. Cloud storage offers flexibility and scalability, but it also involves recurring fees, network latency, and potential security risks.

- The storage architecture and design: Data storage can be organized and designed in different ways, such as file systems, block storage, object storage, or distributed storage. Each of these architectures has its own implications for the cost, complexity, and efficiency of data storage. For example, file systems are easy to use and manage, but they can suffer from fragmentation, metadata overhead, and limited scalability. Object storage is more scalable and flexible, but it also requires more metadata and network bandwidth. Distributed storage can improve performance and reliability, but it also increases the cost of synchronization, replication, and coordination.

- The storage policies and practices: Data storage can be optimized and reduced by applying various policies and practices, such as compression, deduplication, encryption, tiering, archiving, or deletion. Each of these techniques can help save storage space, improve security, or comply with regulations, but they can also introduce trade-offs and challenges. For example, compression can reduce the size of data, but it can also degrade the quality or increase the processing time. Encryption can protect the data from unauthorized access, but it can also increase the storage overhead and complexity. Deletion can free up storage space, but it can also result in data loss or legal issues.

These factors, and others, can have a significant impact on the cost of data storage. Therefore, it is important to evaluate and compare the different options and alternatives available, and choose the best solution for the specific needs and goals of the data. By doing so, one can achieve the optimal balance between cost and value, and maximize the return on investment (ROI) of data.

2. Analyzing the Initial Investment

One of the most significant factors that affect the cost of data storage is the hardware that is used to store and access the data. Hardware costs can vary widely depending on the type, capacity, performance, and durability of the devices that are chosen. Moreover, hardware costs are not only incurred at the time of purchase, but also throughout the lifecycle of the devices, as they require maintenance, upgrades, replacements, and disposal. Therefore, it is important to analyze the initial investment as well as the total cost of ownership (TCO) of the hardware devices that are used for data storage. Some of the aspects that should be considered when analyzing the hardware costs are:

- The type of storage device: There are different types of storage devices that can be used for data storage, such as hard disk drives (HDDs), solid state drives (SSDs), tape drives, optical discs, flash drives, and cloud storage. Each type of device has its own advantages and disadvantages in terms of cost, capacity, performance, reliability, and power consumption. For example, HDDs are cheaper per unit of storage than SSDs, but they are slower, less reliable, and more power-hungry. SSDs are faster, more reliable, and more energy-efficient than HDDs, but they are more expensive and have lower capacities. Tape drives are very cheap and have high capacities, but they are slow, prone to degradation, and require manual intervention. Optical discs are also cheap and durable, but they have low capacities and slow access speeds. Flash drives are small, portable, and fast, but they have limited lifespans and can be easily lost or damaged. Cloud storage is convenient, scalable, and accessible, but it has recurring fees, security risks, and dependency on internet connectivity.

- The capacity of the storage device: The capacity of the storage device refers to the amount of data that can be stored on it. The capacity of the device determines how much data can be stored and for how long. The capacity of the device also affects the performance and the power consumption of the device. For example, a larger capacity device can store more data, but it may also take longer to access, transfer, or backup the data. A larger capacity device may also consume more power and generate more heat than a smaller capacity device. Therefore, it is important to choose the appropriate capacity of the device based on the data storage needs and the budget constraints.

- The performance of the storage device: The performance of the storage device refers to the speed and efficiency of the device in storing and accessing the data. The performance of the device affects the quality and the productivity of the data storage and usage. The performance of the device is measured by various metrics, such as latency, throughput, bandwidth, IOPS, and seek time. For example, latency is the time it takes for the device to respond to a data request. Throughput is the amount of data that can be transferred per unit of time. Bandwidth is the maximum rate of data transfer that the device can support. IOPS is the number of input/output operations that the device can perform per second. Seek time is the time it takes for the device to locate the data on the device. These metrics can vary depending on the type, capacity, and configuration of the device. For example, SSDs have lower latency, higher throughput, higher bandwidth, higher IOPS, and lower seek time than HDDs. Therefore, it is important to choose the device that can deliver the desired performance level for the data storage and usage.

- The durability of the storage device: The durability of the storage device refers to the longevity and the reliability of the device in storing and preserving the data. The durability of the device affects the availability and the integrity of the data. The durability of the device is influenced by various factors, such as the quality, the design, the usage, the environment, and the maintenance of the device. For example, the quality of the device depends on the materials, the components, and the manufacturing process of the device. The design of the device depends on the architecture, the features, and the standards of the device. The usage of the device depends on the frequency, the intensity, and the type of the data operations that are performed on the device. The environment of the device depends on the temperature, the humidity, the dust, the vibration, and the electromagnetic interference that the device is exposed to. The maintenance of the device depends on the cleaning, the testing, the updating, and the repairing of the device. These factors can affect the lifespan, the failure rate, and the error rate of the device. For example, a device that is made of high-quality materials, has a robust design, is used moderately, is stored in a controlled environment, and is maintained regularly can last longer, fail less, and produce fewer errors than a device that does not meet these criteria. Therefore, it is important to choose the device that can offer the highest durability for the data storage and preservation.

These are some of the aspects that should be considered when analyzing the hardware costs of data storage. By comparing and contrasting the different types, capacities, performances, and durabilities of the storage devices, one can make an informed decision about the initial investment and the TCO of the hardware devices that are used for data storage. Additionally, one can also consider the trade-offs, the trends, and the innovations that are related to the hardware costs of data storage. For example, one can weigh the benefits and the drawbacks of using hybrid or tiered storage systems that combine different types of storage devices to optimize the cost and the performance of data storage. One can also follow the trends and the innovations that are happening in the field of data storage, such as the development of new storage technologies, the improvement of existing storage technologies, and the reduction of storage costs. By doing so, one can keep up with the changing and evolving landscape of data storage and make the best use of the hardware devices that are available for data storage.

In summary, operational costs form a significant part of the TCO for data storage. By understanding these intricacies, organizations can make informed decisions, optimize resource allocation, and strike a balance between performance and cost-effectiveness. Remember, it's not just about storing data; it's about managing it sustainably in a rapidly evolving digital ecosystem.

4. How Data Growth Impacts Costs?

One of the most pressing issues that organizations face when it comes to data storage is how to cope with the increasing volume and variety of data. Data growth is inevitable and exponential, as more sources and types of data are generated and collected every day. However, data growth also implies higher costs for storing, managing, and analyzing data. In this section, we will explore some of the challenges and trade-offs that data growth poses for data storage costs, and how organizations can address them effectively. Some of the factors that affect the cost of data storage are:

1. Storage media and infrastructure: The choice of storage media and infrastructure depends on the performance, capacity, availability, and durability requirements of the data. Different types of storage media have different costs per unit of storage, such as hard disk drives (HDDs), solid state drives (SSDs), tape drives, optical discs, and cloud storage. Additionally, the storage infrastructure also involves costs for hardware, software, maintenance, power, cooling, and space. For example, a data center may require servers, racks, switches, cables, backup generators, fire suppression systems, and security measures. The cost of storage media and infrastructure can vary significantly depending on the vendor, the technology, and the scale of the storage solution.

2. Data lifecycle management: data lifecycle management refers to the policies and processes that govern how data is created, stored, accessed, used, and disposed of throughout its lifespan. data lifecycle management can help optimize the cost of data storage by ensuring that data is stored in the most appropriate and cost-effective location, format, and medium at each stage of its lifecycle. For example, data that is frequently accessed and updated may be stored in high-performance SSDs, while data that is rarely used or archived may be stored in low-cost tape drives or cloud storage. Data lifecycle management can also help reduce the cost of data storage by deleting or purging data that is no longer needed, relevant, or compliant with regulations.

3. Data quality and governance: Data quality and governance refer to the standards and practices that ensure the accuracy, completeness, consistency, and security of data. data quality and governance can affect the cost of data storage by influencing the amount and type of data that is stored, as well as the frequency and complexity of data operations. For example, data quality and governance can help avoid storing duplicate, erroneous, or outdated data, which can reduce the storage space and improve the performance of data applications. Data quality and governance can also help protect data from unauthorized access, modification, or loss, which can prevent data breaches, fines, or reputational damage.

5. Protecting Your Information

One of the most important aspects of data storage is ensuring that the data is safe and secure from unauthorized access, theft, corruption, or loss. data security costs can vary depending on the type, size, and sensitivity of the data, as well as the level of protection required. Data security costs can be divided into two main categories: preventive costs and reactive costs.

- Preventive costs are the expenses incurred to prevent data breaches or incidents from happening in the first place. These include costs such as:

1. Encryption: This is the process of transforming data into an unreadable format that can only be decrypted with a key. Encryption can protect data both at rest (stored on a device or a server) and in transit (transferred over a network or the internet). Encryption can be done at different levels, such as file, disk, database, or application level. The cost of encryption depends on the encryption algorithm, the encryption software or hardware, and the performance impact on the system.

2. Authentication: This is the process of verifying the identity of a user or a device that wants to access the data. Authentication can be done using various methods, such as passwords, PINs, biometrics, tokens, or certificates. The cost of authentication depends on the complexity and security of the method, the number of users or devices, and the frequency of access.

3. Authorization: This is the process of granting or denying access to the data based on the user's or device's identity, role, or permissions. Authorization can be done using various mechanisms, such as access control lists, role-based access control, or attribute-based access control. The cost of authorization depends on the granularity and flexibility of the access rules, the number of users or devices, and the frequency of access changes.

4. Backup: This is the process of creating and storing copies of the data in a separate location or medium. Backup can protect data from accidental deletion, corruption, or loss due to hardware failure, natural disaster, or human error. Backup can be done using various methods, such as full, incremental, or differential backup, and various media, such as tapes, disks, or cloud storage. The cost of backup depends on the amount and frequency of the data to be backed up, the backup method and media, and the recovery time objective.

5. Audit: This is the process of monitoring and recording the activities and events related to the data, such as who accessed the data, when, where, how, and why. Audit can help detect and prevent data breaches or incidents, as well as comply with regulatory or legal requirements. Audit can be done using various tools, such as logs, alerts, reports, or dashboards. The cost of audit depends on the volume and complexity of the data, the level of detail and analysis required, and the retention period of the audit records.

- Reactive costs are the expenses incurred to respond to and recover from data breaches or incidents that have already happened. These include costs such as:

1. Investigation: This is the process of identifying the source, scope, and impact of the data breach or incident. Investigation can involve various activities, such as forensic analysis, data recovery, root cause analysis, or incident response. The cost of investigation depends on the severity and duration of the data breach or incident, the expertise and resources required, and the legal or regulatory implications.

2. Notification: This is the process of informing the affected parties, such as customers, employees, partners, or authorities, about the data breach or incident. Notification can involve various channels, such as email, phone, mail, or media. The cost of notification depends on the number and type of the affected parties, the urgency and sensitivity of the information, and the legal or regulatory obligations.

3. Remediation: This is the process of restoring the data and the system to their normal state after the data breach or incident. Remediation can involve various actions, such as data restoration, system repair, security update, or policy change. The cost of remediation depends on the extent and complexity of the damage, the availability and compatibility of the solutions, and the downtime and disruption caused.

4. Compensation: This is the process of providing financial or non-financial benefits to the affected parties, such as refunds, discounts, credits, or free services. Compensation can help mitigate the negative consequences of the data breach or incident, such as loss of revenue, reputation, or trust. The cost of compensation depends on the value and type of the benefits, the number and satisfaction of the affected parties, and the legal or contractual obligations.

5. Litigation: This is the process of facing legal actions or disputes from the affected parties, such as lawsuits, fines, or penalties. Litigation can result from the violation of the data protection laws or regulations, or the breach of the data privacy or security agreements. The cost of litigation depends on the nature and outcome of the legal actions or disputes, the expertise and resources required, and the reputation and goodwill at stake.

Data security costs can have a significant impact on the overall cost of data storage. Therefore, it is important to assess the data security risks and requirements, and implement the appropriate data security measures and practices, to protect the data and the business from potential threats and losses.

6. Comparing Cost Models

One of the most important factors to consider when choosing a data storage solution is the cost. However, the cost of data storage is not only determined by the price of the hardware or software, but also by the operational and maintenance expenses, the scalability and flexibility, the security and reliability, and the performance and efficiency of the system. Depending on the needs and preferences of the organization, different cost models may be more suitable than others. In this section, we will compare two of the most common cost models for data storage: cloud and on-premises.

- Cloud storage refers to storing data on remote servers that are managed by a third-party provider, such as amazon Web services (AWS), Microsoft Azure, or google Cloud platform (GCP). The provider is responsible for the infrastructure, security, backup, and maintenance of the data, and the customer pays only for the amount of storage space and bandwidth they use. Some of the advantages and disadvantages of cloud storage are:

- Advantages:

1. Lower upfront costs: Cloud storage does not require any initial investment in hardware, software, or installation. The customer can start using the service immediately and scale up or down as needed.

2. Higher scalability and flexibility: Cloud storage can easily accommodate changes in data volume, velocity, or variety, without requiring any additional resources or configuration. The customer can also access the data from anywhere and anytime, as long as they have an internet connection.

3. Better security and reliability: Cloud storage providers offer multiple layers of protection, such as encryption, authentication, firewalls, and backup, to ensure the safety and availability of the data. The customer can also benefit from the redundancy and fault tolerance of the cloud, which can prevent data loss or corruption due to hardware failure, natural disaster, or human error.

- Disadvantages:

1. Higher ongoing costs: Cloud storage charges the customer based on the amount of data stored and transferred, which can vary depending on the usage patterns and the pricing plans of the provider. The customer may also incur additional costs for data retrieval, migration, or integration with other systems or applications.

2. Lower control and customization: Cloud storage limits the customer's ability to modify or optimize the system according to their specific needs or preferences. The customer has to rely on the provider's policies and procedures, which may not always align with their own. The customer may also face compatibility or interoperability issues with other data sources or platforms.

3. Potential latency and performance issues: Cloud storage depends on the speed and quality of the internet connection, which can affect the data transfer and access times. The customer may also experience delays or disruptions due to network congestion, bandwidth limitations, or service outages. The customer may have to compromise on the performance or efficiency of the system, especially for data-intensive or time-sensitive applications.

- On-premises storage refers to storing data on local servers that are owned and managed by the customer, within their own premises or data center. The customer is responsible for the infrastructure, security, backup, and maintenance of the data, and the customer pays for the total cost of ownership (TCO) of the system. Some of the advantages and disadvantages of on-premises storage are:

- Advantages:

1. Lower ongoing costs: On-premises storage does not incur any recurring fees or charges for the storage space or bandwidth. The customer only pays for the initial purchase and installation of the hardware and software, and the occasional upgrades or replacements. The customer can also optimize the system to reduce the power consumption and operational expenses.

2. Higher control and customization: On-premises storage gives the customer full authority and autonomy over the system, allowing them to configure or modify it according to their specific needs or preferences. The customer can also integrate the system with other data sources or platforms, without any compatibility or interoperability issues.

3. Better latency and performance: On-premises storage does not depend on the internet connection, which can improve the data transfer and access times. The customer can also ensure the performance or efficiency of the system, by allocating sufficient resources and applying appropriate techniques or tools.

- Disadvantages:

1. Higher upfront costs: On-premises storage requires a significant investment in hardware, software, and installation, which can be costly and time-consuming. The customer also has to bear the risk of depreciation or obsolescence of the system, as technology evolves rapidly and new solutions emerge frequently.

2. Lower scalability and flexibility: On-premises storage can be difficult to adjust to changes in data volume, velocity, or variety, as it may require additional resources or configuration. The customer may also face challenges in accessing the data from different locations or devices, as they have to ensure the connectivity and compatibility of the system.

3. Worse security and reliability: On-premises storage relies on the customer's own measures and capabilities to protect and maintain the data, which may not be adequate or effective. The customer may also suffer from data loss or corruption due to hardware failure, natural disaster, or human error, as they have to provide their own backup and recovery solutions.

To illustrate the differences between cloud and on-premises storage cost models, let us consider an example of a hypothetical organization that needs to store 100 TB of data for 5 years. Assuming that the average annual growth rate of the data is 10%, the average monthly data transfer rate is 10%, and the average data retrieval rate is 5%, we can compare the estimated costs of using AWS S3 (a cloud storage service) and a self-built NAS (a on-premises storage system) based on the following assumptions and parameters:

- AWS S3:

- Storage price: $0.023 per GB per month

- Data transfer price: $0.09 per GB

- Data retrieval price: $0.01 per GB

- Data deletion price: $0.01 per GB

- Average annual price reduction: 5%

- Self-built NAS:

- Hardware cost: $10,000 per 10 TB

- Software cost: $1,000 per year

- Installation cost: $5,000

- Power cost: $0.1 per kWh

- Maintenance cost: 10% of hardware cost per year

- Average annual hardware replacement: 10%

- Average annual hardware failure: 5%

Using a simple spreadsheet model, we can calculate the total cost of ownership (TCO) of each option over 5 years, as shown below:

| Year | AWS S3 TCO | Self-built NAS TCO |

| Total | $182,814 | $396,732 |

As we can see, the cloud storage option has a much lower TCO than the on-premises storage option, mainly due to the lower upfront and maintenance costs. However, this may not always be the case, as the cost of cloud storage can vary depending on the usage patterns and the pricing plans of the provider. Moreover, the cost is not the only factor to consider, as there are other aspects such as security, performance, and flexibility that may influence the decision. Therefore, the best cost model for data storage depends on the specific needs and preferences of the organization, and the trade-offs they are willing to make.

7. Unforeseen Expenses in Data Storage

When it comes to data storage, many organizations tend to focus on the upfront costs of hardware, software, and maintenance. However, these are not the only factors that affect the total cost of ownership (TCO) of data storage. There are also hidden costs that may not be apparent at first glance, but can have a significant impact on the budget and performance of data storage systems. These hidden costs include:

1. Data growth: Data is constantly being generated, collected, and stored by various sources and applications. This means that the demand for data storage capacity is always increasing, and so is the cost of acquiring and managing more storage devices. Data growth can also lead to data sprawl, where data is scattered across different locations and formats, making it harder to access, analyze, and secure.

2. Data protection: Data is one of the most valuable assets of any organization, and it needs to be protected from loss, corruption, theft, or unauthorized access. Data protection involves implementing backup, recovery, encryption, and security measures to ensure the availability, integrity, and confidentiality of data. However, data protection also comes with a cost, such as the cost of additional storage space, bandwidth, software licenses, and personnel.

3. Data compliance: Data is subject to various regulations and standards, depending on the industry, location, and type of data. Data compliance requires adhering to the rules and policies that govern the collection, storage, processing, and disposal of data. Data compliance can incur costs such as the cost of auditing, reporting, archiving, and deleting data, as well as the cost of fines and penalties for non-compliance.

4. Data quality: Data is only useful if it is accurate, complete, consistent, and relevant. data quality refers to the degree to which data meets the expectations and requirements of the users and applications that consume it. Data quality can affect the efficiency, effectiveness, and reliability of data storage systems, as well as the outcomes and decisions based on data analysis. Data quality can entail costs such as the cost of data cleansing, validation, integration, and enrichment.

These hidden costs can vary depending on the type, size, and complexity of data storage systems, as well as the business goals and strategies of the organization. Therefore, it is important to consider these hidden costs when evaluating and comparing different data storage options, and to optimize the data storage systems to minimize these costs and maximize the value of data. For example, some possible ways to reduce the hidden costs of data storage are:

- Adopting a data lifecycle management (DLM) approach, which involves classifying, prioritizing, and moving data across different storage tiers based on its value, usage, and retention period.

- leveraging cloud-based data storage services, which offer scalability, flexibility, and cost-effectiveness, as well as data protection, compliance, and quality features.

- Implementing data deduplication and compression techniques, which reduce the amount of redundant and unnecessary data, and thus save storage space and bandwidth.

- utilizing data analytics and artificial intelligence (AI) tools, which can help identify and eliminate data errors, anomalies, and inconsistencies, and enhance data quality and value.

8. Optimizing Costs Over Time

One of the most important aspects of data storage is managing the costs over time. Data has a lifecycle that consists of different stages, such as creation, processing, storage, access, and deletion. Each stage has different costs and benefits associated with it, and these may change over time depending on the business needs, the data value, and the technological advancements. Therefore, it is essential to optimize the costs of data storage throughout the data lifecycle, by applying various strategies and techniques. Some of these are:

- Data tiering: This involves storing data in different types of media, such as solid-state drives (SSDs), hard disk drives (HDDs), tape, or cloud, based on the performance, availability, and durability requirements. Data that is frequently accessed or has high value can be stored in faster and more expensive media, such as SSDs, while data that is rarely accessed or has low value can be stored in slower and cheaper media, such as tape or cloud. This way, the overall cost of data storage can be reduced, while meeting the service level agreements (SLAs) and the quality of service (QoS) expectations.

- Data compression: This involves reducing the size of data by applying algorithms that eliminate redundant or irrelevant information, such as whitespace, metadata, or repeated patterns. Data compression can save storage space, bandwidth, and power consumption, and thus lower the cost of data storage. However, data compression also has some drawbacks, such as increased CPU usage, latency, and potential data loss or corruption. Therefore, data compression should be applied carefully, considering the trade-offs between the benefits and the risks, and the type and characteristics of the data.

- Data deduplication: This involves identifying and eliminating duplicate copies of data that are stored in multiple locations, such as backup systems, archives, or cloud storage. Data deduplication can reduce the amount of data that needs to be stored, transferred, and managed, and thus lower the cost of data storage. However, data deduplication also has some challenges, such as ensuring data integrity, security, and privacy, and managing the metadata and the pointers that link the original and the duplicate data. Therefore, data deduplication should be implemented with caution, considering the impact on the data availability, reliability, and recoverability.

- Data retention and deletion: This involves determining how long data should be kept and when it should be deleted, based on the legal, regulatory, and business requirements, and the data value and relevance. Data retention and deletion can help optimize the cost of data storage by freeing up storage space, reducing the data management overhead, and minimizing the risk of data breaches or compliance violations. However, data retention and deletion also have some implications, such as ensuring data accessibility, consistency, and auditability, and preserving the data history and context. Therefore, data retention and deletion should be governed by clear and consistent policies and procedures, and enforced by automated and secure mechanisms.

9. Navigating the Complex Landscape of Data Storage Expenses

As we have seen throughout this article, the cost of data storage is not a simple or straightforward calculation. It depends on a variety of factors, such as the type, size, and format of the data, the storage medium and technology, the security and compliance requirements, the backup and recovery strategies, the scalability and performance needs, and the business value and usage patterns of the data.

Each option and technology has its own advantages and disadvantages, such as cost, performance, reliability, scalability, security, and compatibility. By comparing different storage options and technologies, you can choose the best fit for your data and budget.

3. Evaluate the hidden and indirect costs of data storage. The cost of data storage is not only determined by the purchase price or the monthly fee of the storage solution, but also by the hidden and indirect costs that may arise from the storage operation and maintenance. These costs may include the cost of power, cooling, space, labor, software, hardware, upgrades, migration, integration, support, downtime, data loss, data breach, and compliance. By evaluating the hidden and indirect costs of data storage, you can avoid unexpected expenses and reduce the risk of data storage failures.

4. Align your data storage strategy with your business strategy. Data storage is not an isolated or independent activity, but a part of the overall business strategy. The ultimate goal of data storage is to support the business value and outcomes of the data, such as improving customer satisfaction, increasing operational efficiency, enhancing innovation, or gaining competitive advantage. By aligning your data storage strategy with your business strategy, you can maximize the value and minimize the cost of your data storage solutions.

By following these aspects, you can navigate the complex landscape of data storage expenses and make informed and strategic decisions about your data storage solutions. Data storage is not a trivial or negligible expense, but a critical and strategic investment that can have a significant impact on the success and sustainability of your business. Therefore, it is essential to understand the true cost of data storage and optimize your data storage strategy accordingly.
