Learn how DevOps can improve collaboration and productivity by bringing agility to both development and operations teams. Understand the challenges involved in adopting the DevOps culture and the strategies to mitigate them.

DevOps is fast emerging as a great way to build and deploy applications that can run both on-premise and cloud alike. DevOps is a philosophy that attempts to bridge the gap between application development and operations for better productivity and reduced costs, risks, and cycle times. If your organization is contemplating a move towards DevOps, many factors need to be considered before this culture is adopted.

Transitioning to the DevOps culture is not easy; it requires a change in the culture and mind-set. We will discuss more on this as we move ahead through this article. This article discusses what DevOps is and why it is becoming increasingly popular. It also highlights the reasons for real-world DevOps failures and how to avoid them.

Why DevOps? Why Does It Matter?

DevOps is a term that is used to refer to a set of proven practices that facilitate collaboration and communication of both development and operations alike. By adopting DevOps, organizations can develop and deploy enterprise applications quickly and seamlessly. DevOps combines cultural philosophies, tools, practices, etc. to increase an organization's agility in the software development process. It enables an organization to deliver applications and services at increased velocity. The building blocks of the DevOps lifecycle can be broadly categorized into the following phases.

  • Continuous Development
  • Continuous Integration
  • Continuous Testing
  • Continuous Monitoring
  • Virtualization
  • Containerization

Why does DevOps matter to the developers? Well, there are certain points to note here. At a quick glance, here's the list of the benefits DevOps provides you:

  • Improved speed
  • Improved collaboration
  • Better security
  • Faster delivery
  • Reliability

DevOps Practices

Are your DevOps ready? To answer this question, you must understand the DevOps principles and practices. You should be aware of what you need to do to improve the operational agility of your software development process. Confused? Relax and read on. Your questions will be answered soon.

DevOps practices are a set of key principles and guidelines that are adopted by an enterprise for automating the software development and infrastructure management processes. Here's a list of some important DevOps practices with a brief overview on each of them.

  • Continuous Integration
  • Continuous Delivery
  • Microservices

Continuous Integration

Continuous integration may be defined as a software development discipline in which the developers are responsible for integrating the code changes to a shared, central repository. Once such changes have been merged, automated tests and builds are then executed. The primary objective of this practice is to identify and detect bugs earlier in the software development life cycle and reduce the time required for software releases. Once the code changes have been checked in to a repository, each of these check-ins is verified using an automated build process followed by appropriate testing methodologies to detect the problems (if any) in the application. Ideally, you can have multiple integrations every day and each integration is followed by an automated build process.

Continuous integration helps detect and solve problems quickly. Note that longer time intervals between integrations make it exponentially more and more difficult to detect and fix issues. Continuous integration helps you and your organization in more ways than one. It helps you to reduce the integration problems, detect errors faster, and increase visibility and communication. You end up spending more time building new features in the application and less time fixing bugs. Hence, continuous integration is a practice that improves the software quality process as a whole.

Continuous Delivery

Continuous delivery may be defined as a software development discipline in which the changes in the code are integrated in a shared repository and such changes are then built and tested so as to make them available for release in the production environment. Essentially, this is a practice that extends continuous integration one step further by deploying the code changes to the production environment. In essence, continuous delivery is a practice that helps you to make faster releases and get feedback faster. It is a practice that enables organizations to adapt software in tune with the needs of the user and market trends. Continuous integration and continuous delivery go together; the latter is just a natural extension of the former. Continuous delivery ensures that every change can be released seamlessly. Faster feedback improves the quality of the software delivered; you get the feedback early, so you can act fast to get issues resolved.


Microservices is the term given to a set of independently deployable services. Such services are scoped to a particular business function. They typically run in their own environments and are designed to communicate with other services through well-defined interfaces. The microservices architecture is a paradigm shift from the traditional monolithic architectural style for improved scalability, ease of deployment, and performance. Martin Fowler states: "The term ‘Microservice Architecture’ has sprung up over the last few years to describe a particular way of designing software applications as suites of independently deployable services. While there is no precise definition of this architectural style, there are certain common characteristics around organization around business capability, automated deployment, intelligence in the endpoints, and decentralized control of languages and data."

The Challenges Ahead

DevOps attempts to bridge the barrier that exists between the development and operational teams in an enterprise, hence improving the software delivery process and enabling software applications to hit the market early. Despite the benefits that it has to offer, there are many constraints in implementing DevOps in an enterprise. Let's now discuss a few potential challenges that you and your organization might have to face when implementing DevOps. DevOps can only succeed if you provide the right technology and tools. For DevOps to be a success, it is imperative that you are able to develop, test, deploy, monitor, and manage applications seamlessly by applying the proper technology and tools.

Come out of Your Old Habits, Please!

There are challenges aplenty when it comes to implementing DevOps in an enterprise. First off, you as a developer would need to break out of your old habits and your old way of looking at things. The focus should no longer be the quantity of bugs as a measure of software quality. You should understand what led to the bugs in the first place, i.e., what led to the software bug creeping in? Apparently, this implies a paradigm shift from the traditional way of looking at things to an altogether new approach.

Learning New Skills

Resistance to change will be apparent when an enterprise has planned to migrate to the DevOps vision. Learnability is of utmost importance for the success of a DevOps culture in your organization. Success depends on the ability to adapt to change. The team members should have learnability and should be able to come out of their "comfort zone" to learn new skills, tools, and technologies.

Responsibilities of the Leadership

For DevOps to succeed, a lot depends on the leadership as well. Management should preach DevOps as a vision. This paradigm shift needs support from management. Training and support are necessary to inculcate this vision within the employees in an enterprise.

Adopting Microservices

The change from a legacy architecture to the microservices architectural style might be quite challenging. Although microservices has advantages aplenty, you need to be extra careful about defining the right application boundaries, defining the architectural principles, and having a perfect configuration and deployment strategy in place.

The Right Tools and Training

It should be noted that DevOps is more about process and culture rather than the organization itself. You need the right tools to enforce the best practices. Another issue that should be mentioned here is legacy tools usage. If your team is already using tools that don't provide a fast build and release cycle, you should invest in newer tools so that agility can be brought back into your software development life cycle. However, merely introducing new tools might not help; you need to impart the necessary training to ensure that these tools are leveraged to the extent they should be. If the people in your organization are not trained to take advantage of the tools you have decided to use, merely transitioning to a DevOps culture will not be successful.


DevOps is a software development practice that involves continuous development, continuous integration, continuous testing, continuous deployment, and continuous monitoring throughout the software development life cycle. These steps are performed till the time the desired quality of software is delivered. Identifying the right tools for the entire life cycle and imparting training to help bring the team up to speed with those tools is of utmost importance when your organization is planning to go for DevOps.

There are challenges aplenty, but where there is a will, there is a way. A good strategic approach toward adopting DevOps in an enterprise is worth it. It’s better to accept the change than to stay far behind the competition. Despite the challenges, the path to adapting DevOps culture is not all gloom and doom. This article presented an overview of what DevOps is all about, its benefits and challenges, and the strategies that can be adopted to overcome such challenges. Happy reading!
