1. Implications of DevOps


Implications of DevOps

  • The Quality of the deployed changes should of supreme quality. Quality basically means suitability for the use by various stakeholders for whom the changes are made for. These may include the operations team, end users, business teams etc.
  • The delivery mechanism also should of high quality. This implies that the reliability and the repeatability of the delivery mechanism should be high. This implies the tools and processes used during the delivery should be such that the configurations should be repeatable. If the mechanism or processes fail frequently, then there may infact be rise in the delivery timeframes.
  • There are two phases in which the end-to-end delivery cycle can be split up into. The first phase is when the developers develop potentially shippable increments of the software (thru agile or any other development frameworks) and the second phase is with the developed code gets picked up and gets deployed into the production. DevOps demands that the time period between the phase 1 and phase 2 of the lifecycle be as less as possible to achieve a seamless delivery into the production without compromising the quality of the deliverable.
  • Our definition should be goal oriented and not focused on the tools and practices that you use. You may use any tools, any processes, however, the goal that you have decided should be met – be it thru tools, be it thru Agile methods or be it thru waterfall methods. A sample goal could be “reducing time between 2 deployments should be as short as possible”.
  • The goals specified in the definition do not restrict the scope of DevOps practices to testing and deployment. In order to achieve these goals, it is important to include an Ops perspective in the collection of the requirements. i.e. your product backlog should have elements of infrastructure and deployments also and not just functional elements.
