- 4. Introduction Cloud Computing Cloud computing is Internet-based computing, whereby shared resources, software, and information are provided to computers and other devices on demand, like the electricity grid. Cloud computing is a paradigm shift following the shift from mainframe to client-server in the early 1980s. Details are abstracted from the users, who no longer have need for expertise in, or control over, the technology infrastructure "in the cloud" that supports them.
- 5. What is Cloud Computing ? Cloud Computing Cloud computing is Internet based computing where virtual shared servers provide software, infrastructure, platform, devices and other resources and hosting to customers on a pay-as- you-use basis. All information that a digitized system has to offer is provided as a service in the cloud computing model . Users can access these services available on the "Internet cloud" without having any previous know-how on managing the resources involved.
- 6. What is Cloud Architecture ? Cloud Computing Cloud architecture, the systems architecture of the software systems involved in the delivery of cloud computing, typically involves multiple cloud components communicating with each other over application programming interfaces, usually web services.
- 7. Cloud Computing Sample Architecture UNIX philosophy This resembles the UNIX philosophy of having multiple programs each doing one thing well and working together over universal interfaces. Complexity is controlled and the resulting systems are more manageable than their monolithic counterparts Front End The front end is the part seen by the client, i.e. the computer user. This includes the client's network (or computer) and the applications used to access the cloud via a user interface such as a web browser. Significant Components The two most significant components of cloud computing architecture are known as the front end and the back end. Back End The back end of the cloud computing architecture is the “cloud” itself, comprising various computers, servers and data storage devices.

- 9. Public Cloud Public clouds are managed by third parties which provide cloud services over the internet to the public, these services are available as pay-as-you-go billing models. They offer solutions for minimizing IT infrastructure costs and become a good option for handling peak loads on the local infrastructure. Public clouds are the go-to option for small enterprises, which can start their businesses without large upfront investments by completely relying on public infrastructure for their IT needs. The fundamental characteristics of public clouds are multitenancy. A public cloud is meant to serve multiple users, not a single customer. A user requires a virtual computing environment that is separated, and most likely isolated, from other users. Advantages : • High Scalability • Cost Reduction • Reliability and flexibility • Disaster Recovery Disadvantages : • Loss of control over data • Data security and privacy • Limited Visibility • Unpredictable cost
- 10. Private Cloud Private clouds are distributed systems that work on private infrastructure and provide the users with dynamic provisioning of computing resources. Instead of a pay-as-you-go model in private clouds, there could be other schemes that manage the usage of the cloud and proportionally billing of the different departments or sections of an enterprise. Private cloud providers are HP Data Centres , Ubuntu, Elastic-Private cloud, Microsoft, etc. Advantages : • Customer information protection: In the private cloud security concerns are less since customer data and other sensitive information do not flow out of private infrastructure. • Infrastructure ensuring SLAs: Private cloud provides specific operations such as appropriate clustering, data replication, system monitoring, and maintenance, disaster recovery, and other uptime services. • Compliance with standard procedures and operations: Specific procedures have to be put in place when deploying and executing applications according to third-party compliance standards. This is not possible in the case of the public cloud. Disadvantages : • The restricted area of operations: Private cloud is accessible within a particular area. So the area of accessibility is restricted. • Expertise requires: In the private cloud security concerns are less since customer data and other sensitive information do not flow out of private infrastructure. Hence skilled people are required to manage & operate cloud services.
- 11. Hybrid Cloud A hybrid cloud is a heterogeneous distributed system formed by combining facilities of the public cloud and private cloud. For this reason, they are also called heterogeneous clouds. A major drawback of private deployments is the inability to scale on-demand and efficiently address peak loads. Here public clouds are needed. Hence, a hybrid cloud takes advantage of both public and private clouds. Advantages : • Cost : Available in cheap cost than other clouds because it is formed by distributed system. • Speed : It is efficiently fast with lower cost, It reduces latency of data transfer process. • Security : Most important thing is security. Hybrid cloud are totally safe and secured because it works on distributed system network. Disadvantages : • It’s possible that businesses lack the internal knowledge necessary to create such a hybrid environment. Managing security may also be more challenging. Different access levels and security considerations may apply in each environment. • Managing a hybrid cloud may be more difficult. With all of the alternatives and choices available today, not to mention the new PaaS components and technologies that will be released every day going forward, public cloud and migration to public cloud are already complicated enough. It could just feel like a step too far to include hybrid.

- 13. Cloud Computing Service Categories A software distribution model in which a third-party provider hosts applications and makes them available to customers over the internet. EXAMPLES: salesforce, NetSuite and Concur SaaS (Software As a Service) A model in which a third party provider hosts application development platforms and tools on its own infrastructure and makes them available to customers over the internet. EXAMPLES: AWS Elastic Beanstalk, Google App Engine and Heroku PaaS (Platform As a Service) A model in which a third-party provider hosts servers, storage and other virtualized compute resources and makes them available to customers over the internet. EXAMPLES: AWS, Microsoft Azure and Google Compute Engine IaaS (Infrastructure As a Service)

- 16. Conclusion Cloud Computing So, while cloud computing is really great and we're probably already using it, either for business of for personal means, here's what we've learned from taking a look at the pros and cons: Cloud computing is a really cheap way for companies to have all the resources they need in once place. It's a much better way to spread your resources, and it becomes easier to access things from longer distances.
