This presentation provides an overview of cloud computing, including its definition, history, components, architecture, types, advantages and disadvantages. Cloud computing allows users to access shared computing resources like software, storage and servers over the internet. It has grown popular since the 2000s with companies like Amazon, Google and Microsoft offering cloud services. The main types of cloud include public, private and hybrid clouds that vary in their access and management.

- 3. INTRODUCTION 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.
- 4. WHAT IS 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.

- 7. ARCHITECTURE 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.
- 8. SAMPLE ARCHITECTURE 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. The two most significant components of cloud computing architecture are known as the front end and the back end.
- 10. PUBLIC CLOUD Public clouds are made available to the general public by a service provider who hosts the cloud infrastructure. Generally, public cloud providers like Amazon AWS, Microsoft and Google own and operate the infrastructure and offer access over the Internet. With this model, customers have no visibility or control over where the infrastructure is located. It is important to note that all customers on public clouds share the same infrastructure pool with limited configuration, security protections and availability variances.
- 11. PRIVATE CLOUD Private cloud is cloud infrastructure dedicated to a particular organization. Private clouds allow businesses to host applications in the cloud, while addressing concerns regarding data security and control, which is often lacking in a public cloud environment. It is not shared with other organizations, whether managed internally or by a third-party, and it can be hosted internally or externally.
- 12. HYBRID CLOUD Hybrid Clouds are a composition of two or more clouds (private, community or public) that remain unique entities but are bound together offering the advantages of multiple deployment models. In a hybrid cloud, you can leverage third party cloud providers in either a full or partial manner; increasing the flexibility of computing. Augmenting a traditional private cloud with the resources of a public cloud can be used to manage any unexpected surges in workload.

- 16. DISADVANTAGES Dependency Risk Requires a Constant internet Connection Security Migration Issue
- 17. CONCLUSION So, while cloud computing is really really great and you’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.
