- 2. Dept. of ISE Syllabus Module1: CLOUD COMPUTING • Introduction • Cloud computing at aGlance • Historical developments • Building Cloud computing Environments • Amazon web services • Google App engine • Micosoft Azure • Hadoop • Force.com and salesforce • Manjrasoft Aneka
- 3. Dept. of ISE Cloud Computing: • Cloud Computing referred as the accessing and storing of data and provide services related to computing over the internet. It simply referred as it remote services on the internet manage and access data online rather than any local drives. The data can be anything like images, videos, audios, documents, files etc. • Cloud computing is adopted by every company, whether it is an MNC or a startup many are still migrating towards it because of the cost-cutting, lesser maintenance, and the increased capacity of the data with the help of servers maintained by the cloud providers.
- 4. Dept. of ISE • One more reason for this drastic change from the On- premises servers of the companies to the Cloud providers is the ‘Pay as you go’ principle-based services provided by them i.e., you only have to pay for the service which you are using. The disadvantage On-premises server holds is that if the server is not in use the company still has to pay for it.
- 5. Dept. of ISE How Cloud Computing Works: Cloud computing helps users in easily accessing computing resources like storage, and processing over internet rather than local hardwares. Here we discussing how it works in nutshell: • Infrastructure: Cloud computing depends on remote network servers hosted on internet for store, manage, and process the data. • On-Demand Acess: Users can access cloud services and resources based on-demand they can scale up or down the without having to invest for physical hardware. • Types of Services: Cloud computing offers various benefits such as cost saving, scalability, reliability and acessibility it reduces capital expenditures, improves efficiency.

- 13. Dept. of ISE History of Cloud Computing : • Before Computing was come into existence, client Server Architecture was used where all the data and control of client resides in Server side. If a single user want to access some data, firstly user need to connect to the server and after that user will get appropriate access. But it has many disadvantages. So, After Client Server computing, Distributed Computing was come into existence, in this type of computing all computers are networked together with the help of this, user can share their resources when needed. It also has certain limitations. So in order to remove limitations faced in distributed system, cloud computing was emerged.
- 14. Dept. of ISE Evolution of cloud computing
- 15. Dept. of ISE • During 1961, John MacCharty delivered his speech at MIT that “Computing Can be sold as a Utility, like Water and Electricity.” According to John MacCharty it was a brilliant idea. But people at that time don’t want to adopt this technology. They thought the technology they are using efficient enough for them. So, this concept of computing was not appreciated much so and very less will research on it. But as the time fleet the technology caught the idea after few years this idea is implemented. So, this is implemented by Salesforce.com in 1999. • This company started delivering an enterprise application over the internet and this way the boom of Cloud Computing was started.
- 16. Dept. of ISE • In 2002, Amazon started Amazon Web Services (AWS), Amazon will provide storage, computation over the internet. In 2006 Amazon will launch Elastic Compute Cloud Commercial Service which is open for Everybody to use. • After that in 2009, Google Play also started providing Cloud Computing Enterprise Application as other companies will see the emergence of cloud Computing they also started providing their cloud services. Thus, in 2009, Microsoft launch Microsoft Azure and after that other companies like Alibaba, IBM, Oracle, HP also introduces their Cloud Services. In today the Cloud Computing become very popular and important skill.

- 25. Dept. of ISE Building Cloud computing Environment: • The creation of cloud computing environments encompasses both the development of applications and systems. • These developments that leverages cloud computing solutions and the creation of frameworks, platforms and infrastructure delivery cloud computing services.
- 26. Dept. of ISE Application Development • Applications that leverage cloud computing benefit from its capability to dynamically scale on demand. • Web application is the application which takes the biggest advantage of this feature. • Enterprise application :- This application that leverages the internet as the preferred channel for service delivery and user interaction. This application is the complex process which is the interaction with users and develop through the interaction between several tiers behind the web front end.
- 27. Dept. of ISE Resource-intensive applications:- This application can either be data-intensive or compute- intensive application .• For both cases, the considerable amount of resources are required to complete the execution in a reasonable timeframe. .• That the large amount of resources are not needed constantly or for a long duration. ex: Scientific application require huge computing capacity to perform large scale experiments once in a while.
- 28. Dept. of ISE Cloud computing provides a solution for on-demand and dynamic scaling across the entire stack of computing. This is achieved by • Providing methods for renting compute power , storage and networking. • Offering runtime environments designed for scalability and dynamic sizing. • Providing application services that mimic the behavior of desktop applications but that are completely hosted and managed on the provider side.
- 29. Dept. of ISE 2. Infrastructure and System development Distributed computing, virtualization, service Orientation, and Web 2.0 form the core technologies enabling the provisioning of cloud services from anywhere on the globe. I) Distributed computing is a foundational model for cloud computing because cloud systems are distributed systems. The major challenges for developers is that where the new nodes and services are provisioned on cloud. Infrastructure-as-a-service solutions provide the capabilities to add and remove resources. Platform-as-a-service solutions embed into their core offering algorithms and rules that control the provisioning process and lease of resources.
