What is AWS?

How well-versed are you in AWS? If not, don't worry I'll ensure you will have a clear understanding after you finish reading this post.

AWS is a comprehensive cloud computing platform offered by Amazon. Think of it as a vast collection of digital services and resources you can access and use over the internet to build and run your applications or manage your IT infrastructure.

Let's say you want to bring your application to the Internet. You will need a server to deploy your application on and a storage area to store all your databases, files, etc and for that, you will have to manage servers, and storage devices manually.

Here comes AWS, which manages all your work at a very effective cost.

With AWS, you can easily provision and manage resources, scale your applications on demand, and pay only for what you use. It empowers you to focus on your core business and offloads the heavy lifting of infrastructure management to Amazon's reliable and secure platform.

Why is AWS Preferred over Manual Management?

  • easy to use- AWS is designed to allow users to quickly and securely host their applications.

  • flexible- You may choose the web application platform, programming language, operating system, database, and other services you require with AWS. You get a virtual environment through AWS that you may fill with the programs and services your application needs.

  • cost-effective- You pay only for the computing power, storage, and other resources you use, with no long-term contracts or up-front commitments.

  • reliable- You can benefit from a scalable, dependable, and secure global computing infrastructure with AWS, which serves as the virtual foundation for Amazon.com's multi-billion dollar online company and has been refined for more than a decade.

  • Scalable and high-performance- AWS utilizes an end-to-end approach to secure and harden our infrastructure, including physical, operational, and software measures.
