Cloud computing has become popular among Industries and AWS continues to be in the top list of cloud services. Cloud computing freed the organizations from managing their own IT Infrastructure, rather it provides IT-enabled capabilities as a service to the customers.

Advantages of AWS Over On-premises Solutions
- Customers has to pay only for the resources they use
- Organizations can add and subtract AWS resources according to the demand
- Deploy resources within minutes in locations around the globe
- Organizations can concentrate more on their projects leaving the infrastructure maintenance tasks
- No advance payments, monthly payment for variable usages
- Flexible capacity
When you build on-premises infrastructure there are lot of things needs to be considered. You need expensive hardware and it should be maintained on the regular basis. With the use of AWS, you can avoid these activities and you just need to pay for the resources you consume. AWS has multiple pricing models which allows us to optimize cost for both stable and variable workloads.
Predicting the customer requirements for the application often ends up with limited capacity or expensive resources. Using the cloud computing services you can provision the exact amount of resources you need and also if you need more, you can easily scale up. The elastic nature of cloud enables you to select the appropriate compute resources according to the demand.
