A Guide to DevOps Adoption and Implementation in 2020
DevOps that is a contraction of development and operations help development teams rapidly deliver high-quality solutions. The methodology helps in the quick development and deployment of software solutions. Adoption of DevOps leads to improved security posture and productivity of the development team.
Companies are increasingly adopting DevOps as an alternative to the traditional agile and waterfall development methodologies. According to Gartner, the adoption of DevOps practices will increase by about 40 percent today to 90 percent by 2022.
What is DevOps?
DevOps was introduced in the late 2000s due to the shortcomings of traditional methodologies – Waterfall, Agile, and Sscrum – in meeting the needs of modern development teams. The methodology was created to remove barriers that prevent a team from working efficiently.
The traditional development methodologies focused mostly on efficiency. Other factors, such as timely evaluation and delivery, were not much of a concern.
However, time is a critical factor for development teams. Customers are mostly impatient and want quick results. Project delays and missed deadlines are the common reasons for projects to get canceled.
DevOps overcomes the shortcomings of traditional methodologies by focusing on efficiency and rapid development. Evaluation using traditional models typically takes weeks or months during which time a team has to move to different tasks. In contrast, evaluation in DevOps takes only a few days, and even hours. This allows the development teams to react quickly to change requests and deploy solutions that meet specifications.
The adoption of DevOps can help a team become more efficient and agile. It promotes the quick delivery of solutions without compromising on quality.
Implementation of DevOps: 5 Key Steps Explained
DevOps can help organizations to quickly and reliably deploy solutions. The implementation of DevOps allows them to benefit from the scale of operation. The development model supports the team to complete their projects quickly through close collaboration.
The foundations of DevOps include automated provisioning, continuous two-way feedback, and quality assurance. Effective implementation of the methodology involves understanding the various components that together support the efficient and reliable deployment of solutions.
1. Automated Processes
Automation is at the heart of the DevOps model that promotes rapid deployment. DevOps automation leads to continuous monitoring and improvement. It allows faster execution of required tasks throughout the development lifecycle.
The mantra with DevOps is ‘Automate Everything’. Automation can be employed for code development, configuration, and monitoring changes. Additionally, automation can be extended to code testing to ensure high performance, reliability, and security.
Software-defined automation should be in place for continuous testing and monitoring. Automated provisions should allow solutions to move from development to testing and deployment quickly without requiring unnecessary resources.
At the same time, organizations shouldn’t set the development process on auto-pilot and forget about it. They need to continuously monitor the automated processes to ensure that the results meet project objectives.
2. Close Team Collaboration
DevOps don’t consider development teams to be working in silos. It places importance on team integration and collaboration. Implementation of DevOps requires processes and tools that result in close collaboration between the team members.
Organizations should invest in tools that lead to enhanced teamwork. The focus should be on sharing resources instead of reinventing new processes. A platform should be created for the team to efficiently share resources and information.
Various tools can be used for ensuring increased coloration for the team. An example of a collaboration tool is Confluence that provides effective collaboration through a tightly-integrated ticketing functionality. Other tools that can be used for improved collaboration include PmWiki and TikiWiki that help in the contribution and sharing of information.
3. Change Management and Continuous Integration
DevOps processes encourage integrated change management to easily adjust to the changing circumstances. The team should prioritize and address changes that might have a wider impact. Additionally, the team members should continuously update the code in the repository. Integrations should be carried out continuously and frequently.
An integrated change management approach leads to improved effectiveness of the team members in adjusting to the changes. It results in the continuous delivery of high-quality products that meet the specifications of the end client.
4. Rigorous Testing
The updated code should be tested by a quality assurance team. Both automated and manual testing should be carried out at different stages from coding to deployment. The code should be automatically deployed once it passes the checks of the QA team.
Testing should check the quality and security of the overall solution. The test data should be assigned to applications to test its integrity and pass it to the developers for rework if required.
QA team should define the acceptance tests for each deployment. They need to create tests for ensuring the integrity of applications, infrastructure, and data. Automated testing tools should run hundreds and thousands of tests to test the quality of the code. Manual testing should also be carried out to ensure that the final product is without any flaws.
5. Continuous Feedback and Improvement
Continuous feedback is important to identify inefficiencies. Team members should be provided with timely feedback to resolve issues. The feedback loop should start with the coding and continue during the testing of the solution. It can be implemented through real-time monitoring and automated alerting.
Feedback obtained from the production department should be adopted by the development team. The goal of the feedback should be to improve the security, reliability, and performance of the end product. Continuous feedback will help the development team to improve the codes and deploy quality solutions.
The main reason for the increased adoption of the DevOps methodology is that it leads to an improved ability to operate at high speed and scale without compromising quality. Implementation of the methodology allows a team to break free from the technical and administrative bottlenecks that prevent quick deployment.
DevOps can promote automation and close team collaboration that helps achieve the scale of operations. However, the security aspect should not be ignored when adopting the methodology. Developers need to know about secure coding using modern security testing technologies.
