CLOUDING REVIEW

CLOUDING REVIEW

You can use it as work at your environment, its a clean state.Its just like a new PC that you buy.So, install a fresh operating system on your PC, and then you can configure it to be anything,and solve any software you want, and then it can serve you as you require.Right?And that is what EC2 does as well.Right?So, this is the Compute Domain.Next up, we have the Migration domain.So, Migration domain is when you want to transfer your data to the AWS infrastructure or youwant to transfer your data back from AWS infrastructure.Next up we have the Migration Service.So, this Migration service is used to transfer data to and from the AWS Infrastructure.So, if you have petabytes scale of data in your data center and you want to send it toAWS Infrastructure, you will be using services in migration.Now, there is a service called Snow Ball in migration, which is used to physically transferyour data to AWS Infrastructure.Right?So, basically what AWS does is, it sends you a physical device which is just like a harddrive, to your premises and you transfer your data on to it, then AWS sends it back to theInfrastructure.Now, this is Snowball.So, it offers similar services in the migration services.Now, you would ask me, why are we sending our data physically to AWS Infrastructure?Why not through the Internet?So, like I said, if you have petabytes scale of storage in your Data Centre, and you haveto send it to AWS Infrastructure, it is better to send it physically rather than sendingit on the internet.You can imagine it, just like giving some data to your employees, would you give iton a hard drive, on an external hard drive, if the data is large?Or would you send them an e-mail regarding that?Right.So, just like that you can imagine this scene.Next up, we have the Domain : we have security and identity compliance.In security and identity compliance, you have services like IAM, which is used to authenticateusers and define user rights to them.Say, suppose you are running a company and you have a root AWS account.
