What is cloud computing?
Cloud computing is the delivery of IT resources over the internet on demand. Instead of buying, owning, and maintaining physical servers and data centers, you can access a variety of IT resources such as compute power, storage, databases, networking, analytics, and more from a cloud provider like AWS. You only pay for what you use, when you use it, and you can scale up or down as needed.
Some of the benefits of cloud computing are:
Cost savings: You can avoid upfront capital expenses and reduce operational costs by paying only for what you use.
Agility: You can quickly provision and release IT resources as your business needs change.
Elasticity: You can scale your IT resources up or down automatically or manually depending on the demand.
Reliability: You can ensure high availability and fault tolerance by using multiple servers and data centers across different regions.
Security: You can protect your data and applications by using encryption, firewalls, access control, and compliance standards.
Innovation: You can experiment with new technologies and services without risking your existing infrastructure.
