Reduce the time between updates/fixes
Achieve speedy delivery
Improve time to recovery
DevOps Transformational Roadmap
The DevOps implementation approach is categorized into three main stages of the software development lifecycle:
Build (DevOps Continuous Integration)
Test (DevOps Continuous Testing)
Release (DevOps Continuous Delivery)
The concept of DevOps implementation integrates development, operations, and testing departments into collaborative cross-functional teams with the aim of improving the agility of overall IT service delivery.
The focus of DevOps is mostly on easing delivery processes and standardizing development environments with the aim of improving efficiency, security, and delivery predictability. DevOps empowers teams and gives them the autonomy to build, deliver, validate, and support their software applications. It provides developers with a better understanding of the production infrastructure and more control of the overall production environment.
As an organization, your DevOps journey begins by defining the existing business procedures, IT infrastructure, and delivery pipelines, followed by crafting clear objectives that the DevOps implementation strategy is expected to achieve for your organization.
Although DevOps is implemented with different variations in different organizations, the common phases of the DevOps process consist of the 6C’s as discussed below:
Continuous Development – Continuous development involves planning, outlining, and introducing new code. The aim of continuous development is to optimize the procedure of code-building and to reduce the time between development and deployment.
Continuous Integration (CI) – This practice of DevOps implementation involves the integration of developed code into a central repository where configuration management (CM) tools are integrated with test & development tools to track the code development status. CI also includes quick feedback between testing and development to be able to identify and resolve various code issues that might arise during the process.
Continuous Testing – The aim of continuous testing is to speed up the delivery of code to production. This phase of DevOps involves simultaneous running of pre-scheduled and automated code tests as application code is being updated.
Continuous Delivery – Continuous delivery is aimed at quick and sustainable delivery of updates and changes ready to be deployed in the production environment. Continuous delivery ensures that even with frequent changes by developers, code is always in the deployable state.
Continuous Deployment (CD) – This practice also automates the release of new or changed code into production, similar to continuous delivery. The use of various container technology tools such as Docker and Kubernetes allows continuous deployment as they play a key role in maintaining code consistency across different deployment environments.
Continuous Monitoring – It involves ongoing monitoring of the operational code and the underlying infrastructure supporting it. Changes/application deployed in the production environment is continuously monitored to ensure stability and best performance of the application.
Advantages of DevOps
Some of the key benefits of DevOps implementation include:
Speedy and better product delivery
Scalability and greater automation
High clarity into system outcomes
Stable operating environments
Better utilization of resources
High clarity into system outcomes
Does that mean there are no hurdles to DevOps adoption?
Not necessarily! Similar to any other approach, DevOps adoption also comes with certain hiccups. Although the concept of DevOps is a decade old now, there are certain aspects that need to be taken care of so that they don’t become hurdles in embracing the collaborative IT practice. Let us have a look at some of the key points.
a) Cost Reduction
DevOps implementation reduces the number of project failures and rollbacks, and as a result, reduces the overall IT cost in the long run. However, if not planned properly, the cost of shifting to DevOps practice can burn a hole in your pocket. Planning the budget is a crucial step before DevOps implementation.
b) Skill Deficiency
Hiring competent DevOps professionals is a necessity when it comes to successful DevOps adoption in any organization. To achieve this, it is imperative to hire skillful DevOps consultants capable of managing the teams and building a collaborative culture.
c) Complex Infrastructure
Infrastructure complexity is yet another challenge in successful DevOps implementation as organizations find it challenging to create a common infrastructure out of different services and apps deployed in isolated environments. Educating teams on why the organization has decided to make the shift to DevOps, planning the DevOps implementation roadmap, and hiring competent DevOps consultant to go a long way in managing the complex infrastructural changes.
DevOps Implementation – Step-By-Step Guide
1. Build a Competent DevOps Team
The first step before you move to any new technology is the proper identification of resources and building a team competent enough to take on the challenges that come with the execution of an IT project. Some of the qualities to look for while identifying members of the DevOps team include critical thinking to find the root cause of the issue, proficiency in the latest DevOps tools and zeal to learn new ones, and an ability to troubleshoot and debug efficiently to solve the problems. A competent team can execute flawless delivery of software starting from collating requirements, planning the implementation path, and finally deploying the software.
2. Develop a Robust DevOps Strategy
The DevOps implementation strategy is essentially built on six parameters:
- Speedy execution – The ultimate objective of any organizational initiative is customer satisfaction, which is based on constant innovation and faster execution. Continuous delivery and continuous deployment of DevOps practice ensure that accuracy and speed are maintained.
Scalability – Infrastructure-as-code practice assists in scalable and immaculate management of various stages (development, testing, and production) of the software product lifecycle, which is vital to DevOps success.
Reliability – DevOps practices of continuous integration, continuous testing, and continuous delivery guarantee reliability of operations by ensuring safe and quality output for a positive end-user experience.
Collaboration – The DevOps principle of cross-team collaboration and effective communication reduce process inefficiencies, manage time constraints, and trim the chances of project failure.
Frequent Delivery – Continuous delivery, integration, and deployment practices of DevOps allow very rapid delivery cycles and minimum recovery time during implementation, leaving room for more innovation.
Security – Various automated compliance policies and configuration management techniques allow the DevOps model to offer robust security through infrastructure as code and policy as code practices.
3. Start Small
It is wise to start with small initiatives before making an organizational shift to DevOps. Small-scale changes provide the benefit of manageable testing and deployment. The next steps of DevOps implementation at the organizational level should be decided based on the outcome.
4. Automate as Much as Possible
Considering the fact that fast and speedy execution lies in the backbone of DevOps, automation becomes crucial to your implementation strategy. With carefully chosen automation tools, manual hand-offs are eliminated, and processes are carried out at a faster speed, saving time, effort, and the total budget of the organization.
5. Prepare the Right Environment
For successful DevOps implementation, it is crucial to prepare the right environment of continuous testing and continuous delivery. Even a small change in the application should be tested at different phases of the delivery process. Similarly, preparing a constant delivery environment ensures that any change or addition of code is quickly deployed to production, depending on the success or failure of the automated testing.
6. Choose the Right Tools and Build a Robust Common Infrastructure
This is one of the most critical steps of the DevOps implementation process. The selection of tools should be based on their compatibility with your unique IT environment for smooth integration. The right toolset allows you to build a robust infrastructure with customized workflows and access controls, which provides enhanced usage and smooth functionality.
There are a number of DevOps tools that help in ensuring effective implementation; however, finding the best ones requires continuous testing and experimentation. The primary objective of these tools is to streamline and automate the different stages of the software delivery pipeline/workflow.
