DevOps is a predominant model for delivering high-quality software, and the sector shows no signs of slowing down. Shifts in mindsets and methods are a natural element of DevOps-centric software development because the DevOps community is continually looking for ways to improve development speed and productivity.
DevOps benefits and challenges
- The following are some of the advantages of DevOps:
- fewer silos and improved communication across IT groups;
- faster time to market for products
- fast improvement in response to input
- there is less downtime;
- enhancements to the entire software development pipeline, including builds, validations, and deployment;
- owing to automation, there is less menial labor;
- simplified development procedures as a result of greater development responsibility and code ownership; and
- a greater range of responsibilities and abilities.
However, there are numerous DevOps challenges:
- changes to the organization and IT department, including new skills and job roles;
- expensive tools and platforms, as well as the training and support required to use them effectively;
- the growth of development and IT tools;
- unnecessary, unstable, or unsafe automation;
- implementing DevOps across several projects and teams;
- higher risk of deployment due to a failure-fast mentality and job generalization rather than specialization;
- adherence to regulations, particularly where role separation is essential; and
- the emergence of new bottlenecks
Key success factors of DevOps
Product & Service Ownership
Customer orientation is a key characteristic (and advantage) of any Agile or DevOps approach. The organization should evolve to accommodate new ownership roles to facilitate this cultural transition to a focus on customer value.
Product and Service Owners are in responsibility of gathering and prioritising requirements in the backlog, as well as ensuring that business value is delivered at every stage. Their supervision ensures that user value is maintained and that all contributors are aware of these priorities.
As a result, establishing Product or Service Owner positions in the organisation and enabling them to carry out their goals is one of the most crucial parts of DevOps success.This enables these new jobs by giving them rights and responsibilities, as well as monitoring their performance against customer satisfaction KPIs.
A DevOps strategy is built on breaking down silos. Setting up multi-skilled teams that include all stakeholders engaged in the creation and support of the service/product is how practitioners get there. Collaboration and efficient, open communication among team members are boosted by cross-departmental teams.
Not only does this eliminate the time and ambiguity associated with collaborating with someone from a different organizational unit, but it also allows team members to learn from one another. Over time, information sharing leads to the development of better services or goods.
Use DevSecOps to enhance security
The production of fancy new features is given a high priority in a hyper high-speed Agile environment, frequently at the price of product security and robustness considerations. While DevOps can help by linking Dev and Ops teams, there’s more you can do to improve product design from the start.
DevSecOps allows you to integrate security into product delivery procedures. You may find and fix vulnerabilities early, accomplish continuous improvement in product security, and standardize the use of mature DevSecOps methods internally by moving security to the left of the lifecycle.
The CI/CD automation toolbox for DevOps
While the Agile manifesto emphasizes “individuals and interactions over processes and tools,” this does not preclude the use of tools. The correct tooling can help decrease errors, development time, and costs by dramatically simplifying specific procedures and operations.
In fact, for version control, configuration management, build, source control, monitoring, and more, successful DevOps teams rely heavily on a variety of technologies and software platforms. Continuous Integration and Deployment (also known as Continuous Delivery) are primarily achieved by a clever automation method, which is a DevOps keyword. Automation is more crucial than ever when it comes to testing.
DevOps involves a lot of testing to achieve good product quality. However, testing entails a significant amount of time that could be better spent developing new features. To achieve continuous delivery, DevOps teams attempt to automate testing as much as feasible.
KPIs and monitoring
Continuous learning and improvement, as well as a consistent attempt to find and fix problems throughout the lifecycle, are at the heart of DevOps. Monitoring is therefore critical – both in terms of the final product and in terms of ensuring control over development processes.
To succeed at DevOps, you’ll need to set up a metric system that allows you to track and analyze process flow, velocity, and team (and, in certain circumstances, individual) performance. Define KPIs to track DevOps targets such as “escaped defects” and “cycle time,” and use these measures to enhance performance.
Important findings of DevOps
- DevOps has successfully “crossed the chasm”: Across industries, organizations are continuing to increase their DevOps knowledge, especially among the top performers. The percentage of firms with elite performers has nearly tripled, at 20%. This backs with what other industry analysts have said.
- The cloud is more likely to be used by elite performers: Cloud computing offers several critical advantages, including quick auto-scaling, cost transparency, and stability. The best DevOps teams were 24 times more likely than the worst to execute on all five cloud computing characteristics outlined by the National Institute of Standards and Technology (NIST), including on-demand self-service, broad network access, resource pooling, quick elasticity, and measurable service.
- The vast majority of cloud users are underutilizing it: Only 29% of cloud users met all five of NIST’s above-mentioned criteria. This underlines the fact that companies claiming to use cloud computing may not have adopted all of the necessary patterns for obtaining elite performance, preventing them from realizing the cloud’sbenefits.
- For the first time, industry matters: The retail industry performed better in this year’s assessment, both in terms of speed and stability. However, as in past years, there was no evidence that any other industry is performing better or worse. This shows that DevOps methods may help organizations of all types and sizes, even those in highly regulated areas like financial services, government, and retail, achieve high levels of performance.
- There is no “one-size-fits-all” solution, but collaborative efforts are key to success: When it comes to DevOps capabilities, especially in large organizations, the focus should be on both team- and organization-level activities. At the team level, continuous integration, automated testing, and monitoring are some of the activities that work well. The capacity to define architectural or modification approval policies that transcend departments and teams is an example of organization-level capabilities. The paper deconstructs these skills and shows the tactics to employ to maximize the impact of a DevOps strategy.
- Low performers utilize proprietary software more than high and elite performers: Because the expense of maintaining and supporting proprietary software can be prohibitive, high and elite performers choose to use open source alternatives. This is consistent with prior reports’ findings. In fact, according to the 2018 Accelerate State of DevOps Report, high performers are 1.75 times more likely to use open source components, tools, and platforms extensively.
Improvement in DevOps
Performance and productivity are two study models included in DevOps improvements.
The performance research model examines the constructs and levers that can be used to improve organizational performance, including how cloud, continuous delivery, disaster recovery testing, explicit change management, and culture of psychological safety can all help with software delivery. The study also discovered that heavyweight change processes are ineffective.
The productivity study model reveals that investing in easy-to-use tools and information search, adopting a culture of psychological safety, and lowering technical debt can all help firms boost engineer productivity. Improved productivity also aids in achieving a better work-life balance for employees and decreases burnout.
