What if developers want to leverage branch deployments but don't have a full ChatOps stack integrated with their repositories? We wanted to set out to find a way for all developers to be able to take advantage of branch deployments with ease, right from their GitHub repository, and so the branch-deploy Action was born!
As businesses reorganize for DevOps, the responsibilities of teams throughout the software lifecycle inevitably shift. Operations teams that traditionally measure themselves on uptime and stability—often working in silos separate from business and development teams—become collaborators with new stakeholders throughout the software lifecycle. Development and operations teams begin to work closely together to build and continually improve their delivery and management processes. In this blog post, we’ll share more on what these evolving roles and responsibilities look like for IT teams today, and how operations help drive consistency and success across the entire organization.
To better understand how DevOps changes the responsibilities of operations teams, it will help to recap the traditional, pre-DevOps role of operations. Let’s take a look at a typical organization’s software lifecycle: before DevOps, developers package an application with documentation, and then ship it to a QA team. The QA teams install and test the application, and then hand off to production operations teams. The operations teams are then responsible for deploying and managing the software with little-to-no direct interaction with the development teams.
These dev-to-ops handoffs are typically one-way, often limited to a few scheduled times in an application’s release cycle. Once in production, the operations team is then responsible for managing the service’s stability and uptime, as well as the infrastructure that hosts the code. If there are bugs in the code, the virtual assembly line of dev-to-qa-to-prod is revisited with a patch, with each team waiting on the other for next steps. This model typically requires pre-existing infrastructure that needs to be maintained, and comes with significant overhead. While many businesses continue to remain competitive with this model, the faster, more collaborative way of bridging the gap between development and operations is finding wide adoption in the form of DevOps.
Over the past decade, the maturation of the public cloud has added complexity to the responsibilities of operations teams. The ability to rent stable, secure infrastructure by the minute and provide everything as a service to customers has enabled organizations to deploy rapidly and frequently, often several times per day. Smaller, faster delivery cycles give organizations the critical capability of improving their customer experience through rapid feedback and automated deployments. Cloud technologies have made development velocity a fundamental part of delivering a competitive customer experience.
Cloud technologies have transformed how we deliver and operate software, impacting how we do DevOps today. Developers now focus more on stability and uptime in addition to developer velocity, and operations teams now have a stake in developer velocity along with their traditional role of maintaining uptime. When it comes to the specific role of operations in DevOps, this often means:
- Enabling self-service for developers. In order to support developer velocity—and minimize risks that stem from “shadow operations”, where developers seek their own solutions—operations teams work more closely with developers to provide on-demand access to secure, compliant tooling and environments.
- Standardized tooling and processes across the business. The best way to enable a sustainable self-service model and empower teams to work more efficiently together is by standardizing on the tooling that is in use. Tools and processes that are shared across the business unit enable organizational unity and greater collaboration. In turn, this reduces the friction developers and operations teams experience when sharing responsibilities.
- Bringing extensible automation to traditional operations tasks. As operations teams focus more on empowering other teams through self-service and collaboration, there is less time to handle other work. Traditional operations tasks like resolving incidents, updating systems, or scaling infrastructure still need to be addressed—only smarter. When development and operations unite under DevOps, operations teams turn to automation for more of the repeatable tasks and drive consistency across the organization. This also enables teams and business units to track and measure the results of their efforts.
- Working and shipping like developers. As operations teams shift more towards greater automation, ‘X’ as code becomes the new normal. Like application source code, the code controlling operations systems needs to be stored, versioned, secured, and maintained. As a result, the development-operations relationship starts to feel more balanced on both sides: operations specialists become more like the developers and more familiar with their working models, and in some organizations, developers become more like operations, sharing in the responsibility of debugging problems with their own code in production.
While it’s well understood that DevOps requires close collaboration between teams, we’re often asked “How are development and operations functions really coordinated in a DevOps model?” At GitHub, we’re fortunate to partner with thousands of businesses every year on improving their DevOps practices. Sometimes these organizations focus on the clearest target, asking developers and delivery teams to go to market faster while paying less attention to the post-deployment operations teams.
However, we find the best results come through improving the practices of all the teams involved in the software lifecycle, together. Operations teams aren’t simply infrastructure and process owners for the organizations, but are also a critical part of the feedback loop for development. Try it out for yourself—a small pilot project that includes developers, release engineering, operations, and even InfoSec can give more teams the momentum they need. It can give them confidence to continue their work, establish best practices, and even train others within your organization along the way.
