The key to mainframe DevOps success is in quickly identifying and removing major bottlenecks in the application delivery lifecycle. Major challenges include collaboration between mainframe and distributed teams, lack of visibility into the impact of software changes, and limited resource flexibility with scaling out necessary testing initiatives. Now let's take a closer look at some of these key challenges and how IT departments can address them ...
The number of apps needed to to fully embrace digital transformation is increasing each year, and organizations are relying on their IT staff to meet and support this need. However, IT isn't always equipped to handle this increased demand. According to the 2017 State of Application Development Report, 62 percent of IT managers reported having a large app development backlog, with some having more than 10 apps waiting to be developed. To get this issue under control CIOs must create a well-defined app strategy that includes providing the tools developers need and incorporates a DevOps approach.
The Insatiable Need for Apps
Gartner predicts that market demand for app development is growing at a rate that is at least five times faster than IT's capacity to deliver it. As this issue grows, organizations will need to be realistic about the apps they need versus the apps they want. Having a realistic strategy is one of the foundational elements of a successful digital transformation initiative.
Most organizations take more than three months to fully develop a new app. That's too long considering how many apps need to be built in a year. It's not just about how long it takes to build these apps — there are budget constraints, skills gaps, competing priorities, and an overall lack of developers to actually build the apps. Digital transformation is a worthwhile investment, but it's no small undertaking. It requires new tools, new processes and in some cases, new hires.
Speeding up Development with DevOps
According to Gartner, 32 percent of businesses say that they need weekly releases, and of those 48 percent say IT delivers more slowly than needed. Often, IT departments will have multi-skilled development teams each with their own specialized tools, frameworks and coding languages. This model results in team and project siloes and hinders collaboration that could make development more efficient.
DevOps is part of the answer to this issue. DevOps teams work together to accelerate delivery of digital solutions, without sacrificing quality. Adopting a DevOps approach involves changing up processes, integrating new technologies, and can't be implemented overnight. When tackling a DevOps transition, organizations must think about three important areas: people, process and technology.
Changing team structures is not simple and asking two teams to start working together means both teams must be involved in the planning phase. The teams must be aligned on goals and processes ahead of time. It's also important that Dev and Ops understand each other's roles and how they both contribute to their shared goals. Once teams establish mutual respect and an open a path of communication, approaching a joint endeavor will be easier, smoother and ultimately, more successful.
To stay in sync and keep the lines of communication open, Dev and Ops should have periodic cross-functional meetings, project aligned or cross-functional email lists, and interdisciplinary chats. Both Dev and Ops can use these channels to stay in constant communication to share information about the development status, test results, deployment stages, and production performance of application projects. Ensuring all team members have a complete understanding of the state of their work and how it fits into the larger teams assignments and initiatives enables more efficient development.
As organizations adopt DevOps, it's important to establish processes to accommodate the new working relationship between process workflows. Over time, organizations will likely form smaller cross-functional teams established to tackle specific projects.
Like a cross-functional scrum team in agile development, these DevOps teams will have resources with both Dev and Ops skills and should be empowered to work closely together with a focused goal. The focus and communication on cross-functional teams is instrumental to one of the most important new processes that is foundational to DevOps: the implementation of continuous feedback loops for all teams and stakeholders.
The key to DevOps success is ensuring everyone understands the state of the application at every stage of the application lifecycle, including production. This requires implementing processes by which status information can be shared with the appropriate team. Sharing information on test results, deployment status, and runtime performance is key, but for it to be truly effective, there must be processes that support and empower team members to take action to resolve any issues as needed.
Over time, many organizations acquire different tools to support DevOps. They can end up with a complex variety of solutions for code validation, version control, continuous integration, automated deployment, test automation, and more. This level of ecosystem complexity consumes time and budget.
To maximize efficiency and reduce complexity, IT teams can bring in low-code development platforms. Low-code platforms can help with version control, collaborative development, build validation, testing and QA, and much more. Having all of these components in one solution can help dramatically increase the speed of DevOps teams.
Low-code can also help alleviate the growing skills gap and talent shortage, by giving aspiring developers the tools they need to build modern applications. These platforms also improve speed for all developers regardless of skill level.
As IT teams try to keep up with the ever-rising demand for apps within enterprises, they will inevitably turn to DevOps and low-code if they haven't already. As DevOps adoption rises, tools will evolve to enable even more efficient development. The backlogs may be long now, but the industry is quickly catching up.
