The document outlines the advantages and disadvantages of deploying solutions on on-premise versus cloud servers, highlighting flexibility, cost efficiency, maintenance, security, and scalability as key factors. On-premise solutions offer physical control over data and lower long-term costs, while cloud servers provide predictable expenses, disaster recovery options, and ease of scaling. Organizations must consider their specific needs, including security requirements and potential costs for robust protection of cloud infrastructure.
On premise vs cloud server
- 1. A business case for deploying your solution on Cloud if you're looking for flexibility of minimal investments, quick commencement of Web & Mobile App, choice of tenure, ability to migrate as and when required, ability to integrate and many more such advantages.
- 2. ON-PREMISE VS CLOUD SERVER On-Premise – Advantages Cloud Servers – Advantages 1. On-premises can be an ideal solution for those who only want an initial investment (CAPAX) for the system set-up. 2. Can be cheaper on longer run. 3. Maintenance costs can be kept to a minimum if scaling your business isn’t the goal. 4. No third party access to the data 5. Physical control over the data 6. There’s no need for an internet connection to access the data, if it is within same physical network 7. Physical control over your back-up system 8. If solution architecture is designed with horizontal scaling facility then it is possible to scale-up with less efforts 1. Lower cost of ownership and comes under the OPEX 2. Comparatively low IT maintenance costs 3. Off site data storage 4. Productivity from anywhere, personal presence is not required 5. Almost all the vendors provides 99.99% uptime 6. Disaster recovery assistance and auto backup functions 7. Easily upgrade or downgrade (Scale-up/Scale-down)
- 3. Areas that vary depending on which solution you deploy include: Costs Security Agility and Scalability Maintenance Backup & Disaster Recovery
- 4. ON-PREMISE VS CLOUD SERVER On-Premise – Cost Cloud Servers – Cost High Capital expense costs 1. Hardware 2. Storage/Space 3. Power 4. Cooling 5. Disaster recovery 6. IT Team (Highly skilled) 7. Maintenance 8. Training On-Going Cost 1. Upgrade dependent applications and licenses 2. IT Team cost as it requires more number of persons along with higher skills comparing the Cloud servers Advantage Can be slight cost efficient in a long run, if scale- up/scale-down is not required Low Capital expense cost 1. Subscription Fee 2. IT Team is lean On-Going Cost 1. Subscription Fee 2. IT team cost with less number of people Advantage 1. Predictable subscription pricings 2. Costs allocated to OPEX 3. No upfront hardware/software cost
- 5. ON-PREMISE VS CLOUD SERVER On-Premise – Security Cloud Servers – Security Customizable Security can be highly customizable to organization’s processes, requirements and regulatory compliances. Disadvantages Whether due to inexperience or insufficient practices in proper security protocols, it stands to reason that critical information is at risk no matter where it is stored. Due to which it requires dedicated & knowledgeable resources. So, if you do cloud vs on-premise cost comparison, add the cost of a robust security system to protect your infrastructure. Advantage No third party access to the data. Highly-secure data encryption is essential for any online business and with cloud computing, it’s all included in the package. Data is secured and backed-up at regular intervals, allowing for access to information as and when needed. Disadvantage Though most vendors are rigorous with their security practices and follow the global regulatory standards, it takes a leap of faith to place that information in someone else’s hands. Cloud servers is aggressively targeted by hackers. Advantage By purchasing additional data security package, it can deliver superior data security.
- 6. ON-PREMISE VS CLOUD SERVER On-Premise – Agility and Scalability Cloud Servers – Agility and Scalability Advantages As team has physical control over the hardware means upgrades can be tightly controlled. Disadvantage Planning in advance is a key part while changes are required. It requires time, thorough research, purchase and deploy hardware. Pre-requisite software licenses (e.g. Microsoft server, SQL server etc.) must be procured separately and needs to be managed manually. Its tricky and lengthy process to downsize the physical servers, it’s possible if the deployed application is designed with horizontal scaling facility. Advantages Pay as you use. Cloud resources can be rapidly adjusted to accommodate specific demand. Disadvantage Costs may increased if the cloud infrastructure is not properly managed. Few of the cloud providers (e.g. MS Azure) provides platform as a services in which business doesn’t need to procure additional pre-requisite software licenses. Easily scale up the infrastructure during the Pick Time of the usage and scale down during the low usage. In which instances can be upscaled and downscaled as per the requirements.
- 7. ON-PREMISE VS CLOUD SERVER On-Premise – Maintenance Cloud Servers – Maintenance On-premise deployment is susceptible to hardware failures that may result in downtime of all hosted solutions. Hence, the IT Team has to perform an additional task of preventive maintenance and keep hardware backup as a failsafe. On-premise network and hardware performance requires to be monitored & managed on regular intervals that usually requires a dedicated resource (network engineers, etc.) Upgradation of all the installed pre-requisite software (security patches, IIS updates, etc.) needs to be managed by the IT Team. Most cloud vendors provide 99.99% uptime guarantee, so the business (tenants) doesn’t need to be concerned about the hardware failures. No need to monitor & manage the network and hardware performance by the business (tenants) as it is the cloud vendor’s responsibility to maintain their uptime and comply to the performance guarantee. Cloud vendor manages the upgradation for all its tenants. So, the business doesn’t need to invest any time-efforts. Business always gets upgraded/latest versions of all the pre-requisite software.
- 8. ON-PREMISE VS CLOUD SERVER On-Premise – Backup & Disaster Recovery Cloud Servers – Backup & Disaster Recovery Disaster Recovery and regularly scheduled backup plans are a necessity. With on-premises deployment, this must architected and implemented by specialized personal from IT Team. Backup and disaster recovery is scalable to the growth of the business and only pay what you use. Backing up to the cloud can happen as often as every 15 mins. Additional services of Disaster Recovery and backup can be availed through cloud vendors directly. Easily connect to cloud from anywhere, using any devices.
