AWS pricing is efficient ?Amazon took a dynamic approach to pricing its hosting when launching AWS. Every service is like pay only when you use. This makes a lot of sense for server infrastructure, as traffic tends to be very bursty, especially the larger the site is.Traditional hardware, for the most part, goes unutilized for 90% of its lifecycle. AWS helps deal with this problem by keeping it cheap during the slow times.
Most Used Components of AWS ?
The key components of AWS are
Simple Storage Device or (S3): It is a storage device and the most widely used AWS
Elastic Compute Cloud (EC2): It provides on-demand computing resources for hosting
applications. It is very useful in case of unpredictable workloads
Elastic Block Store (EBS): It provides persistent storage volumes that attach to EC2 to
allow you to persist data past the lifespan of a single EC2
CloudWatch: To monitor AWS resources, It allows administrators to view and collect

management for your AWS accountAMI and Instance Usage?

hardware of the host computer used for your instance. Each instance type provides different
compute and memory capabilities. Once you launch an instance, it looks like a traditional host,
and we can interact with it as we would with any computer.Sending requests to S3 ?
Amazon S3 is a REST service, you can send request by using the REST API or the AWS SDK
wrapper libraries that wrap the underlying Amazon S3 REST API.Vertical Scalability an Amazon instance? How?
Yes, you can vertically scale on Amazon instance. For that
Spin up a new larger instance than the one you are currently running
Pause that instance and detach the root webs volume from the server and discard
Then stop your live instance and detach its root volume
Note the unique device ID and attach that root volume to your new server
And start it again
Why AWS pricing is efficient ?
Amazon took a refreshing approach to pricing its hosting when launching AWS. Every service is “a la carte”, meaning you pay for what you use. This makes a lot of sense for server infrastructure, as traffic tends to be very bursty, especially the larger the site is.
Traditional hardware, for the most part, goes unutilized for 90% of its lifecycle. AWS helps deal with this problem by keeping it cheap during the slow times.
