DevOps is a revolutionary approach to software development that combines the best of software development and IT operations. It enables organizations to stay ahead of the competition, speed up product delivery, and reduce costs.

The DevOps lifecycle is a systematic way of managing the whole DevOps process. It includes a set of practices and processes that help teams deliver better software faster and with fewer errors.

This guide will introduce you to the DevOps lifecycle and explain how you can use it to ensure the successful delivery of your projects.

You will also learn how to integrate DevOps practices into your existing development process.

With the help of this guide, you will be able to streamline your development process, reduce costs, and deliver better software faster.

Benefits of the DevOps Lifecycle

Most organizations have had issues with software delivery and product quality in the past.

DevOps can help solve these problems by improving collaboration and communication between different teams, reducing risk, and increasing the efficiency of your team.

The DevOps lifecycle consists of three main activities:

The 6 Stages of the DevOps Lifecycle

Here are the 6 stages of the DevOps lifecycle in more detail:

Planning: Planning is the foundation of successful delivery. From ideation to product delivery, teams will encounter many unforeseen challenges that require adjustments to the plan.

Planning is a key component of staying ahead of these challenges by anticipating them, communicating them, and adjusting your plan accordingly. You can also use the planning stage to create a joint backlog

between the development and operations teams.

This will help you to avoid prioritization conflicts, reduce the risk of late delivery, and enable you to better track the progress of your team.

Build: Build is the process of converting source code into a deployable artifact. It may include testing, packaging, and deployment. The team might use tools like Jenkins, Bamboo, Gitlab CI, or Travis CI to automate this process.

Test: Test is the activity that ensures your product meets the requirements of your customer and

the business. The goal of testing is to find defects early, so you can fix them before they impact your customers. The test might use automated testing tools, such as Selenium, Cucumber, Cypress, or Robot Framework.

Deploy: Deploy is the process of deploying your code to a production-like environment for testing. The team might use tools like Kubernetes, Docker, or Mesos to automate this process.

Operate: Operate is the process of running your application in a production-like environment. This is where monitoring and incident management takes place. The team might use tools like New Relic, Datadog, or VictorOps to automate this process.

Analyze: Analyze is the process of examining and exploring your data to answer questions, such as “Why did the application fail?” or “What are the most frequently used features?” The team might use tools like Splunk, Grafana, or Datadog to automate this process. Improve: Improve is the process of learning from past experiences and planning for future changes.

This is an ongoing process that applies to every other stage of the lifecycle. The team might use tools like JIRA, Pivotal Tracker, or Trello to automate this process.

Integrating DevOps Practices into Your Existing Process

If you don't want to start from scratch and completely overhaul your existing software development process, then you can integrate DevOps practices into it. This will help you to improve your team's efficiency and product quality without significant changes to your existing processes.

Ideally, you should start with small changes first, such as automating the build and test processes. Once you are comfortable with these changes, you can move on to other practices, such as adopting Agile, using CI/CD, and implementing a service-oriented architecture (SOA).

To integrate DevOps practices into your existing process, you need to identify the bottlenecks in your current workflows and decide which practices can help you overcome them.

You can choose to start with practices that have a high impact on your workflow, such as automating the build and test processes, adopting Agile, and using CI/CD.

Establishing a DevOps Culture

DevOps is more than just a set of tools and processes; it’s a way of working. It’s a culture that emphasizes collaboration and communication between development and operations teams.

To successfully integrate DevOps into your organization, you need to buy-in from all stakeholders. You also need to communicate the benefits of DevOps and show how it can help your organization grow.

A good first step is to define what DevOps means in your organization. You can do this by creating a definition of DevOps or an explanation of what it is.

You can also create a mission statement by asking yourself questions like “Why do we exist?” or “What do we want to achieve?” You can then create a set of values to act as guidelines for your team members.

Automating the DevOps Lifecycle

Automation is one of the core tenets of DevOps. It helps reduce errors, save time and money, and improve your team’s efficiency.

Some teams go as far as to automate all aspects of the DevOps lifecycle. This is referred to as a “full-stack” or “hub-and-spoke” model. While this approach is ideal for very large organizations, it’s not

necessary for smaller teams.

The best way to decide which parts of the lifecycle to automate is to review your current processes and identify pain points. With this information, you can start to create a list of necessary tools and a

timeline for implementation.

When selecting tools for automation, make sure they meet the following criteria: They are open-source. You can host them on your infrastructure and modify them to suit your needs. They are customizable and extensible.

They have an active user base and a large community. They are supported by a reputable company.

Best Practices for Using DevOps

If you want to get the most out of the DevOps lifecycle, you must adhere to certain best practices. Here are some best practices for using DevOps that you can apply to your software development process:
