Short Guide to Successful DevOps Implementation

The term DevOps was created from two words: development (Dev) and operations (Ops). It defines an approach to software creation that unites development, testing, and operations specialists into one collaborative team, as well as ensures an increase in process automation.

In this blog post, we discuss how DevOps works, its advantages and the important steps of the DevOps implementation strategy.

What Is DevOps and Why Is It Important?

DevOps is a cultural and technical practice that aims to break down the traditional barriers between software development (Dev) and IT operations (Ops). The primary goal of DevOps is to streamline the software delivery process, reduce friction, and accelerate the release of high-quality software.

Benefits of DevOps Implementation

DevOps is gaining momentum, being an effective way to improve and accelerate the delivery of software/app/app’s new features to the end-user or customer.

Since the DevOps strategy improves traditional communication between in-house team members and implies complex automation of as many processes as possible, it also brings the following benefits:

  • Short time-to-market
  • Fewer mistakes and better code quality
  • Improved teamwork and understanding of processes
  • Significant cost-savings
  • Simple and efficient upgrade of the product
  • Accelerated debugging and recovery

Getting Ready for DevOps Implementation

To unlock the full potential of DevOps activities, organizations must adopt a culture of teamwork, automation, and constant improvement. With the right tools, a dedicated team, and a commitment to DevOps best practices, any organization can come to faster, reliable, and more smooth software delivery.

Getting Ready for DevOps Implementation

Getting ready for a successful DevOps implementation is vital because it forms the basis for a smooth and efficient software development and delivery process. To start this journey, think about these steps that will lead to a smooth and successful DevOps setup:

Cultural Shift

Make sure your organization is ready for a cultural shift that promotes collaboration, transparency, and a shared sense of responsibility. This shift may involve breaking down traditional hierarchies and creating an environment where everyone feels accountable for the success of the entire process.

Skills Development

Invest in training and upskilling your teams to work with DevOps tools and practices. This includes learning how to use automation, version control systems, and continuous integration/continuous deployment (CI/CD) pipelines.

Training can be both internal and external, and it is essential to keep teams updated on the latest industry trends and technologies.

Tool Selection

Choose the right tools and technologies that suit your specific needs. Selection should be based on factors like your organization’s size, existing infrastructure, and the nature of the applications you develop.

Some popular DevOps tools include Git, Jenkins, Docker, Kubernetes, and Ansible. Make sure the tools you choose are compatible and can be integrated into your workflows.

Define Goals

Set clear objectives and expectations for your DevOps initiative. These goals should be specific, measurable, achievable, relevant, and time-bound (SMART). They can range from reducing deployment times by a certain percentage to achieving a specific level of automation in your processes.

The Stages of the DevOps Implementation Plan

It is always better to start the DevOps implementation process within a relatively small release cycle in order to minimize risks and check out the efficiency of such an approach. In case of success, it will be easy to scale up and use DevOps for some larger projects. Let us now highlight the main DevOps implementation steps.

Create a DevOps implementation strategy

Just like in all the development processes, a lot should be done before the start. Here are the things we can highlight:

Business analysis

The business analysis phase when creating a DevOps implementation strategy serves as the foundation for the entire DevOps journey. It confirms the plan is accurately designed, matches business objectives, and can achieve more than just technical enhancements – it can boost overall business competitiveness and success.

Organizing the team

The main challenge in DevOps implementation services is shifting the existing corporate culture — the one with separate teams working on their specific tasks — to a collaborative environment where everyone understands and appreciates the influence of each department to introduce a motivation system and team-building events. All the team members should be open to constant communication as well as learning and utilizing new tools and solutions.

Start of the development process

It’s high time for software engineers to join the development process. The next steps involve meetings and the adoption of new tools.

Architecture and tools

First, there is a need to create the app’s architecture based on the functional requirements and choose the environment resources that will be used: databases, cache systems, messaging systems, third-party libraries, etc.

It is also time to create a disaster recovery strategy and select all the other tools that are going to be utilized, from the framework for smoke tests (like Cucumber or Selenium) to the CI/CD system.

Test-driven development

Start coding using the TDD (test-driven development) approach. This methodology implies that firstly, the team creates tests in accordance with the functional requirements, and only after that it creates a code that will manage to pass those tests.

Automated environment provisioning

The task here is to develop a program or a script that will automatically create and configure all the required resources for all the environments: from a ‘sandbox’ (an isolated environment where each engineer can test whatever wants without affecting the rest of the program) to production.

Set up CI (continuous integration)

Now, we have to configure the continuous integration system that will automatically compile and test the code each time a new change is committed. If a new build is verified, the system will let this code to the master branch. Here are the examples of tools you can use: Jenkins, Bitbucket Pipelines, Bamboo, TeamCity, etc.

Set up CD (continuous delivery)

The CD is inextricably linked to CI and responses for automatically pushing the tests-approved and verified versions of code to the next environment: from development to testing, stage, and production.

Containerization

Traditionally, the app is deployed either on a dedicated server or on a VM (virtual machine). This means that scalability and other changes will require significant effort, so more and more often, DevOps engineers use containerization — the approach that simplifies the process of putting the build into the new environment as well as making changes.

Tools and Technologies for DevOps

Carrying your code and all its dependencies, the container allows the app to run smoothly and reliably when moved between differen
