Two application development and deployment trends -- Agile and DevOps -- are changing the development game. But what does DevOps have to do with cloud computing? Pretty much everything, if you're building and deploying cloud-based applications.
Agile leads to the rise of DevOps, which provides more focus on removing barriers between understanding the needs of the end user, translating those needs into software and then quickly moving that software into production. DevOps, however, isn't just about technology; it's also about people and processes. The core notion is to release high-quality, well-performing code more rapidly than traditional approaches to development, testing and deployment can.
The key concept of DevOps is "continuous," which means we think in terms of how to build, test and deploy applications, as well as how to use automated methods for deployment. Continuous integration and continuous delivery are keys to a successful DevOps program -- with automated releases going out many times a day. The objective is to meet the demands of the end user with as little latency as possible. And that can lead to a return on investment.
Teaming Agile and DevOps with public and private clouds
The days of going from design to development to testing to deployment in very tightly controlled and slow processes are coming to an end. Developers now can press a button to test, integrate, validate and deploy their code into production. And the rise of public and private clouds created the ideal environment for developers to provision centralized application platforms on demand.
Developers building apps on public clouds, such as AWS, know the power of integrating DevOps. AWS has an array of tools and processes available to support the concepts of DevOps, including AWS OpsWorks, AWS CodeDeploy, AWS CodePipeline and AWS CodeCommit.
Private cloud concepts are very similar, but the platforms differ. OpenStack distributions and VMware rule the land in the private clouds, and both actively support DevOps concepts and technologies. In many instances, it's just a matter of pointing code deployment, testing, integration and operations at a public cloud platform -- except that you own and pay for the hardware and software.
The future of Agile and DevOps is bright. DevOps drives efficiency and can better leverage emerging platforms such as public and private clouds. Innovation will occur in the ways developers alter apps to better meet the demands of business users.
