CLOUD COMPUTING

INTRODUCTION TO CLOUD COMPUTING

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 computing power, storage, and databases, on an as-needed basis from a cloud provider

Advantages of Cloud Computing:

  1. Back-up and restore data: Once the data is stored in the cloud, it is easier to get back-up and restore that data using the cloud.

  2. Excellent accessibility: Cloud allows us to quickly and easily access store information anywhere, anytime in the whole world, using an internet connection.

  3. Low maintenance cost: Cloud computing reduces both hardware and software maintenance costs for organizations.

  4. Unlimited storage capacity: Cloud offers us a huge amount of storing capacity for storing our important data such as documents, images, audio, video, etc. in one place.

  5. Data security: Data security is one of the biggest advantages of cloud computing. Cloud offers many advanced features related to security and ensures that data is securely stored and handled.

Cloud Based Services

  1. Software as a service (SaaS)

  2. Platform as a service (PaaS)
