What happens when the user logins to the Netflix? When the user logins to the Netflix database, there are things to be done with your personal database. Amazon RDS is a database platform provided by amazon web services and one of the most common usage of this is to store customer account information. So, when the user logins to the Netflix, it needs to save your credit card details. So, when the user is in Netflix.com which is being hosted in amazon ec2 instance, it stores it in database. If you are signing in , it checks your data with the ec2 server!

Once the user signs in, the entire list or the catalog of the entire shows that Netflix offers. It is also a common use of RDS. When the user signs in, it shows the catalog of the Netflix has to give. Now, there are some scenarios, that we need to know!

Cloud Terminology of Elasticity and Scalability

These are the main benefits of using Amazon cloud services. Let, there be thousands of users and Netflix gets the most users in the evening time! So, by 8 or 9 there are many more users that are currently accessing the amazon! If there are more users are trying to use your system or software, so if the user trying to hit the server, the server is going to crash.

As users get added, AWS adds another instance of EC2 to handle the users. So, there are more instances of EC2 in the server and each of them is accessing to the database. Now, the user can access his or her account. In terms of elasticity, as we roll in after some time, there are lesser number of users using the Netflix account. When this happens, Amazon EC2 loses out its server that are no longer required.

High Availability and Fault Tolerant

If the users come into the Netflix, then the users is not going to crash, so it means it is highly available. In terms of fault tolerant, if the EC2 crashes it can redirect to another instance. So, there is no chance of falling down! Because, a new instance is created! Since, all of the instances are connected to the RDS, there is going to more parody.

RDS is a amazon provisioned database service and is commonly customer account information and cataloging inventory!
