Amazon Web Services (AWS) is a cloud computing platform provided by Amazon. AWS services can offer an organization tools such as database storage, compute power, content delivery and other user-friendly functionality services. to help businesses grow and perform better.

AWS is segregated into 25 global regions having multiple availability zones along with its server. These divided regions allow users to choose geographical limits for their services. AWS holds 31% of the global cloud market share and has a considerable server capacity. It offers flexible pricing, which means a user has to pay money for the hours he/she rented it.

• AWS was launched in 2002. The company wanted to sell its unused infrastructure as a service, or as an offering to customers.
• The idea was met with enthusiasm. Amazon launched its first AWS product in 2006. Four years later, in 2012, Amazon hosted a huge event focused on collecting customer input about

4. Elastic Load Balancer

AWS load balancer balances the load among servers that are deployed at a particular instance. There are three types of load balancers –
Classic load balancer : balances traffic among servers
Application load balancer : balances traffic based on URL of applications
Network load balancer : Balances traffic based on web protocol (HTTP, FTP etc.)

5. Autoscaling

Autoscaling helps to increase or decrease the number of servers needed based on requirements for operation such as CPU usage, memory usage, network throughput etc.
