The on demand self-service delivery of compute power, DB, storage, app, and other IT resources through a cloud services platform via the Internet with pay-as-yo-go pricing is the essence of any cloud and AWS is no different. In short, AWS started as a DataCenter as a service.
When one uses AWS, they are kind of accepting the shared responsibility model, where AWS is responsible for security of the cloud and customers are responsible for security in the cloud, as shown below, and it changes with type of the service:
AWS has something called as metadata resource tags, which can be used to segregate workloads across all AWS Services.
AWS Pricing Calculator can be used to get an estimated cost before moving workloads into the AWS cloud.
AWS Cost Explorer is useful for segregation wise cost by either linked account or linked accounts.
AWS Organizations is a simple way to get consolidated billing and apply common policies by having a master account and then creating department wise accounts under that.
Whenever events affecting customers of AWS occur, AWS Personal Health Dashboard can provide alerts and guidance related to remediation.
AWS Trusted Advisor is an automated tool to check AWS usage against best practices. All AWS customers get access to seven core checks. It gives recommendations related to Cost Optimization, Performance, Security, Fault Tolerance and Service Limits. For complete Trusted Advisor Checks, it is recommended to opt for AWS Business Support.
Where Cloud like AWS shines, is Serverless computing offering. It takes PaaS a step further, by introducing the developers with event driven based architecture, which means whatever code the devs are writing, will get an execution environment when an external event is triggered and they have to pay only for the compute required when the code is executed.
