DevOps teams share one common goal: to increase the frequency and quality of application deployments. AWS CodeStar is described as the AWS service to "quickly develop, build, and deploy applications on AWS.”  DevOps teams can use AWS CodeStar to quickly set up their entire continuous delivery toolchain in minutes for more reliable deployments in consistent environments, as well as less risk of error.  

Automation tools are key for delivering on the philosophy of DevOps: better application and service delivery at high velocity without sacrificing performance. DevOps practices that leverage the latest automation tools and technologies also ensure that their engineering platforms and processes are in place to facilitate continuous delivery, integration, and improvement without sacrificing quality throughout the development process.
