DevOps Strategies: Release Management Part 2

DevOps Practices - Release Management

In addition to the general release management strategies described previously, the general DevOps strategies, and the construction-focused DevOps strategies (including continuous deployment) there are several other release management strategies that support DevOps:

  • Integrated deployment planning.  From the point of view of development teams, deployment planning has always required interaction with an organization’s operations and release management staff; in some cases, via liaison specialists within operations often called release engineers. When you adopt a Disciplined DevOps mindset, you quickly realize the need to take a cross-team approach to deployment planning due to the need for operations staff to work with all of your development teams. This isn’t news to operations staff, but it can be a surprise to development teams accustomed to working in their own, siloed environments (luckily this strategy is built into DAD’s Move Closer to a Deployable Release process goal). If your team is not doing this already, you will need to start vying for release slots in the overall organizational deployment schedule.
  • Standard development and testing environments based on production. Development teams know that the greater the consistency between their development, testing, and production environments the easier it is to test and deploy. In multi-team environments the implication is that this will result in defacto standardization of many aspects of your environments. Developers may choose different development tools, but aspects of the infrastructure such as operating systems, application servers, middleware, databases and so on will become consistent over time to streamline the overall release process.
  • Release service streams. A key tenant of DAD is that every team is unique, and an implication of that is that some teams will need more help than others. Teams will produce different levels of quality, they will have different amounts of automation, they will have different release cadences, and so on. As a result your release management strategy needs to be flexible enough to address these different situations. One way to do so is to offer different server streams, or service levels as it were, to solution delivery teams. For example, you may have a basic release management service stream where release management engineers actively help delivery teams to deploy their solutions into production and even help them to start automating some of their processes. At the other end of the spectrum you may have a continuous delivery service stream for delivery teams that have fully automated their testing and deployment processes and that can be trusted to successfully deploy on their own. And of course you could have several other service streams between those two extremes. The advantage of this approach is that it is very flexible albeit at the cost of slightly greater scheduling complexity.
  • Release blackout periods. Some organizations have periods of time where they choose not to release new functionality into production unless it is absolutely critical. These blackout periods typically occur during high-volumes of business transactions. For example, many North American retail companies will have blackout periods between mid-November and early January for the holiday sales seasons. Many organizations will have blackout periods near the end of their fiscal years to enable them to focus on the process required to close out the year.
  • Shared practices. Although this is really a process improvement issue, it’s worthwhile to point out that whoever is involved with release management should actively strive to share effective practices between teams. Sharing learnings across teams is an important aspect of enterprise awareness.

In the next blog posting in this series we will explore data management strategies that support a DevOps mindset.

There is another release management strategy possibly to add to that list and that is pro-active test environment planning. This technique is used to support the quality and communication of what is being dropped into a test environment for any given release train to ensure testing is not invalidated by poor code drops or unknown config changes.
