Hi there,

AWS is one of the cloud platform where we can create virtual server. With cloud we can use those server with the principle of pay as you go.

For getting good knowledge on Aws you can create a free account from aws.amazom.com .

You will can use the services within the free tier limit and get hands-on experience from there. Also there are white paper available in Aws and the faq related to various services. These can be used to get good knowledge.

While using the Aws services please check that you are using them within free tier limit or you will be charged. Some services are beyond free tier limit.

Good luck!!

Happy learning.

Hope it helps!
