- 6. What is cloud computing? • Cloud computing is the on-demand delivery of IT resources over the Internet with pay-as-you-go pricing. Instead of buying, owning, and maintaining physical data centers and servers, you can access technology services, such as 1. computing power, 2. storage 3. databases on an as-needed basis from a cloud provider like Amazon Web Services (AWS), Microsoft Azure
- 7. What is cloud computing? •Cloud computing is on-demand access, via the internet, to computing resources—applications, servers (physical servers and virtual servers), data storage, development tools, networking capabilities, and more—hosted at a remote data center managed by a cloud services provider (or CSP). The CSP makes these resources available for a monthly subscription fee or bills them according to usage.
- 8. What is cloud computing? •cloud computing is the delivery of computing services— including servers, storage, databases, networking, software, analytics, and intelligence—over the Internet (“the cloud”) to offer faster innovation, flexible resources, and economies of scale. You typically pay only for cloud services you use, helping you lower your operating costs, run your infrastructure more efficiently, and scale as your business needs change.

- 18. Top 10
- 19. Small Cloud Service Providers? • China: Baidu AI Cloud, Huawei Cloud, Kingsoft Cloud, JD Cloud, QingCloud, UCloud • Europe: Bleu (Orange and Capgemini), Hetzner, Leaseweb • Japan and Korea: Fujitsu, NTT, SoftBank, NAVER Cloud, KT Cloud • Private Cloud / Managed Services: Hewlett Packard Enterprise, Rackspace, VMware • SaaS Partners: Salesforce, SAP • SMBs: Heroku, UpCloud, Vultr
- 21. 1. Resources Pooling • Resource pooling is one of the essential features of cloud computing. Resource pooling means that a cloud service provider can share resources among multiple clients, each providing a different set of services according to their needs. • It is a multi-client strategy that can be applied to data storage, processing and bandwidth-delivered services. • The administration process of allocating resources in real-time does not conflict with the client's experience.
- 22. 2. On-Demand Self-Service • It is one of the important and essential features of cloud computing. This enables the client to continuously monitor server uptime, capabilities and allocated network storage. • This is a fundamental feature of cloud computing, and a customer can also control the computing capabilities according to their needs.
- 23. 3. Easy Maintenance • This is one of the best cloud features. Servers are easily maintained, and downtime is minimal or sometimes zero. • Cloud computing powered resources often undergo several updates to optimize their capabilities and potential. • Updates are more viable with devices and perform faster than previous versions.
- 24. 4. Scalability And Rapid Elasticity • A key feature and advantage of cloud computing is its rapid scalability. • This cloud feature enables cost-effective handling of workloads that require a large number of servers but only for a short period. • Many customers have workloads that can be run very cost-effectively due to the rapid scalability of cloud computing.
- 25. 5. Economical • This cloud feature helps in reducing the IT expenditure of the organizations. In cloud computing, clients need to pay the administration for the space used by them. • There is no cover-up or additional charges that need to be paid. Administration is economical, and more often than not, some space is allocated for free. 6. Measured And Reporting Service • Reporting Services is one of the many cloud features that make it the best choice for organizations. The measurement and reporting service is helpful for both cloud providers and their customers. This enables both the provider and the customer to monitor and report which services have been used and for what purposes. It helps in monitoring billing and ensuring optimum utilization of resources.
- 26. 7. Security • Data security is one of the best features of cloud computing. Cloud services make a copy of the stored data to prevent any kind of data loss. If one server loses data by any chance, the copied version is restored from the other server. This feature comes in handy when multiple users are working on a particular file in real-time, and one file suddenly gets corrupted. 8. Automation • Automation is an essential feature of cloud computing. The ability of cloud computing to automatically install, configure and maintain a cloud service is known as automation in cloud computing. It requires the installation and deployment of virtual machines, servers, and large storage. On successful deployment, these resources also require constant maintenance.
- 27. 9. Resilience • Resilience in cloud computing means the ability of a service to quickly recover from any disruption. The resilience of a cloud is measured by how fast its servers, databases and network systems restart and recover from any loss or damage. Availability is another key feature of cloud computing. Since cloud services can be accessed remotely, there are no geographic restrictions or limits on the use of cloud resources. 10. Large Network Access • A big part of the cloud's characteristics is its ubiquity. The client can access cloud data or transfer data to the cloud from any location with a device and internet connection. These capabilities are available everywhere in the organization and are achieved with the help of internet. Cloud providers deliver that large network access by monitoring and guaranteeing measurements that reflect how clients access cloud resources and data: latency, access times, data throughput, and more.
- 29. Cloud Computing Architecture /Components • The Architecture of Cloud computing contains many different components. • It includes 1. Front End - Client infrastructure 2. Applications 3. Services 4. Runtime clouds 5. Storage spaces BACK END 6. Management 7. Security. 8. infrastructure • These are all the parts of a Cloud computing architecture.
- 30. Front End: • The client uses the front end, which contains a client-side interface and application. Both of these components are important to access the Cloud computing platform. The front end includes web servers (Chrome, Firefox, Opera, etc.), clients, and mobile devices. • The backend part helps you manage all the resources needed to provide Cloud computing services. This Cloud architecture part includes a security mechanism, a large amount of data storage, servers, virtual machines, traffic control mechanisms, etc. Back End:
- 31. Important Components of Cloud Computing Architecture 1. Client Infrastructure: Client Infrastructure is a front-end component that provides a GUI. It helps users to interact with the Cloud. 2. Application: The application can be any software or platform which a client wants to access. 3. Service: The service component manages which type of service you can access according to the client’s requirements. Three Cloud computing services are: • Software as a Service (SaaS) • Platform as a Service (PaaS) • Infrastructure as a Service (IaaS)
- 33. Important Components of Cloud Computing Architecture 4. Runtime Cloud: • Runtime cloud offers the execution and runtime environment to the virtual machines. 5. Storage: • Storage is another important Cloud computing architecture component. It provides a large amount of storage capacity in the Cloud to store and manage data. 6. Infrastructure: • It offers services on the host level, network level, and application level. Cloud infrastructure includes hardware and software components like servers, storage, network devices, virtualization software, and various other storage resources that are needed to support the cloud computing model.
- 34. Important Components of Cloud Computing Architecture 7. Management: • This component manages components like application, service, runtime cloud, storage, infrastructure, and other security matters in the backend. It also establishes coordination between them. 8. Security: • Security in the backend refers to implementing different security mechanisms for secure Cloud systems, resources, files, and infrastructure to the end-user. 9. Internet: • Internet connection acts as the bridge or medium between frontend and backend. It allows you to establish the interaction and communication between the frontend and backend.
- 35. Challenges in Cloud Computing
- 36. • Security and Privacy Security and Privacy of information is the biggest challenge to cloud computing. Security and privacy issues can be overcome by employing encryption, security hardware and security applications. • Portability This is another challenge to cloud computing that applications should easily be migrated from one cloud provider to another. There must not be vendor lock-in. However, it is not yet made possible because each of the cloud provider uses different standard languages for their platforms.
- 37. Interoperability • It means the application on one platform should be able to incorporate services from the other platforms. It is made possible via web services, but developing such web services is very complex. Computing Performance • Data intensive applications on cloud requires high network bandwidth, which results in high cost. Low bandwidth does not meet the desired computing performance of cloud application. Reliability and Availability • It is necessary for cloud systems to be reliable and robust because most of the businesses are now becoming dependent on services provided by third-party.
- 38. Legal Issues in Using Cloud Models • Security procedures The majority of companies which implemented cloud solutions and services do not have security procedures in place. • Third party access issues Third-party involvement could be a risk • Intellectual Property Rights Intellectual Property Rights differ from one country to another, so it is not very clear what intellectual property laws will apply in the cloud computing environment. • Confidential data theft attacks • Data stored in the cloud might be compromised or breached. Therefore, most cloud computing providers also offer the customer different levels of security protection, which allows for more enhanced security. Encryption might seem to have failed in protecting data from theft attacks
- 39. Ethical issues in cloud computing Cloud computing is based on a paradigm shift with profound implications on computing ethics. The main elements of this shift are: • the control is relinquished to third party services; • the data is stored on multiple sites administered by several organizations; and • multiple services interoperate across the network. • Unauthorized access, data corruption, infrastructure failure, or unavailability are some of the risks related to relinquishing the control to third party services; moreover, it is difficult to identify the source of the problem and the entity causing it. • The complex structure of cloud services can make it difficult to determine who is responsible in case something undesirable happens.
- 40. EVALUATING THE CLOUD’S BUSINESS IMPACT AND ECONOMICS • Discuss the total cost of ownership for an IT solution. • Compare and contrast the capital expenses and operational expenses of an IT solution. • Describe supply-side savings made available through large-scale, cloudbased data centers. • Describe and discuss the efficiencies gained to providers through multitenant applications. • Describe and discuss the “right sizing” process. • Identify the primary costs of a data center. • Describe how Moore’s law relates to the cloud.
- 41. FUTURE OF CLOUD COMPUTING WITH BUSINESS MODEL
- 42. 1. Increase Storage Capacity • Most of the companies require a place where they can securely store their data. So many businesses are adopting cloud computing and it has been predicted that the Cloud providers will provide more data centers at a lower price as there is a large competition between them. 2. Enhanced Performance of Internet • With the help of the Internet of Things, the quality of the internet can be increased and store data in the cloud, for further analyze & provide enhanced performance. The users expect high-quality fast-loading services and application. The network provided will be faster and the ability to receive and deliver that data will be quick. • 3. Modular Software Will Be Priority • This application will store on different modules, on servers of different Cloud Service. This can also reduce the cost of software as placing components of the program on different storage is economical.
- 43. 4. Internet of Things Along With Cloud Computing • The internet of things is also one of the leading Technology is it comes with continuous innovation in real time Data Analytics and cloud computing. There are many machine- to-machine communication, data, and process occurring. 5. Data Shows How Future Changes • The cloud computing market is growing at 22.8 percent and will exceed $127.5 after 2018. By 2018, 62% of all CRM software will be cloud-based. Moreover, 30% of all application spending is for software as a service based applications. 6. Improvement in Cloud Services • Cloud Computing includes: 1.Infrastructure as a service 2.Platform as a service 3.Software as a service • In the future as the software as a service solution will account for more than 60% of the workload. It also has been predicted that the platform as a service and infrastructure as a service will increase gradually as it has been used in most of the organizations. Cloud Computing is user-friendly and is compatible for both new as well as old organizations.
- 44. Future Services
- 45. 7. Security • The data which are stored in the cloud is secure but not fully. The small companies which are providing cloud services may or may not provide proper security to the data. So in the future, we can prevent from cyber attacks by providing better security. The cloud providers provide better security measures opening balance ways to prevent cyber attacks. 8. Modular Software • Companies are using much software, which is yet to modify. This leads to the fact that cloud computing requires modified software, which will provide better security and facilities. This software will be more user-friendly and flexible to use. One of the major advantages of this software will be that it will save the overall cost as well as time. We can see from the below graph, companies providing services and software are also improving. 9. Economic • If cloud computing will continue to evolve the use of hardware will be less as most of the work will be done with the help of cloud computing and virtualization. We can save the setup cost of software by dividing it and this will lead to decreasing the use of hardware. If the evolution continues the data stored in the cloud will get analyzed with the help of a machine and it won’t require any human.
