How do you know when you have achieved DevOps? and you are likely to get different answers. A practical answer to how do you know when you have DevOps depends on having a definition. While defining DevOps itself has been elusive, an enterprise definition is needed for alignment and progress measurement. Considering that DevOps needs continuous flow to accomplish business goals, it can be said you have DevOps when you have implemented continuous flow for at least one model application.
Complexity can plague the success of DevOps within an organization. Complexity cannot be avoided, as DevOps is complex and will likely continue to be. However, the key to avoiding failure through your DevOps journey is to engage the complexity by using DevOps tenets to implement DevOps. Do not try to boil the ocean. Instead, at each leg in the journey, take inventory of where you are in terms of current goals, state, and best practices. Fine-tune your direction and build your solution using proven continuous delivery methods.
While DevOps offers immense value for software deployment, the adherence to best practices is essential to reduce risk and assure security. Each organization is different and has different security postures. This blog enumerates best practices for security across nine pillars of DevOps: Leadership, Collaborative Culture, Design for DevOps, Continuous Integration, Continuous Testing, Continuous Monitoring, Elastic Infrastructure, Continuous Delivery/Deployment and Continuous Security. Examples of best practices for each pillar are listed. These practices can be used to assess an organization’s maturity within the journey to Continuous Security, often referred to as DevSecOps.
While it is true you can easily “containerize” nearly any software quite quickly, this alone will not realize the benefits of an effective container deployment. Those who are serious about containers will do well to learn from others. In this article we list nine pillars of best practices for containers. While is it clear that containers offer immense value for software deployment, adhering to best practices is essential to realize their value.
Distributed version control systems (DVCS) offer very fast, lightweight and local software change control capabilities that support many parallel code branches across large project code bases. These are compelling benefits for individual developers and development teams. At their heart, DVCS accomplish this by tracking software changes as a series of file system snapshots in local repositories instead of via management of individual file changes in a central database. The DVCS approach is ideal for individuals and small agile teams because it puts control directly in their hands without the need to transact all file changes.
While DevOps is not natural, a supernatural result is achievable with the right cultural transformation supported by good tools that drive collaboration and automated flow between people and tools in the application delivery workflow. Implementing DevOps properly is challenging. DevOps depends on collaboration; smooth process flow from conception through deployment; and feedback between people, processes and technologies. It’s more natural for people and departments to hoard information and centralize control—traits that are contrary to DevOps best practices.
