What Is DevOps?

DevOps definition:

DevOps is a set of cultural practices, philosophies, and tools that enable a company to deliver services and applications faster than usual. It improves their products faster than software development companies that rely on traditional infrastructure management processes. This ability to work quickly allows businesses to gain a competitive advantage while providing superior service to their customers.

It’s an undeniable truth: DevOps teams know what they should be doing, but they rarely do it. In the race to push software out the door, “nice to haves” such as more testing, monitoring, or tighter feedback loops are sacrificed to ” get it done.” DevOps, like diet and fitness, isn’t easy.

“To put it another way, things had to be in a production-ready form at all times: if you wrote it, you had to be there to get it going!”

It’s a phrase that arose by combining two closely related concepts. Agile operations or agile infrastructure is one of these concepts. The application of Lean and Agile techniques to operations is known as Agile operation. 

The second notion is substantially larger, requiring an in-depth understanding of how collaboration between development and operations teams adds value across the software development lifecycle.

DevOps acts as a “peacemaker,” bridging the gap between the development and operations teams and ensuring constant collaboration.

Around 2007, the software development and IT operations communities voiced concerns about the traditional software development approach, which separated developers who developed code from operations who deployed and supported it. 

The phrase DevOps combines the development and functions of the word and refers to the practice of bringing both disciplines together in a single, continuous process.

DevOps vs. Agile

Let’s look at what Agile is and how it varies from DevOps now that we know what it is.

An agile approach is a software development methodology developed in 2001 with the introduction of the agile manifesto. It relies on four ideals and twelve principles that aid in establishing an “agile” software development culture. Agile, in general, emphasizes teamwork, self-organization, and accountability through adoption and a leadership attitude.

The difference:

Agile is an iterative method that emphasizes collaboration, customer feedback, and minor rapid releases, whereas DevOps is a technique of putting development and operations teams together. DevOps emphasizes continuous testing and delivery, whereas Agile emphasizes ongoing change. DevOps necessitates a large squad, whereas Agile necessitates a small group.

DevOps uses both the left and right shifts, whereas Agile uses the shift-left principle. Agile focuses on software development, whereas DevOps provides end-to-end business solutions with rapid delivery.

Agile focuses on functional and non-functional readiness, whereas DevOps focuses on operational and business readiness.

What Are the Benefits of DevOps?

You’ve heard more and more about DevOps as more and more businesses adopt the practice—and with good reason. 

Shortening development cycles has been credited to DevOps, which has resulted in better experiences for both the enterprise and its end users. Here are a few of the critical pros of embracing DevOps.

Focus on Customers Is Renewed.

The move to DevOps is essential because it puts the team back in the customer’s shoes. It’s easy to get into the jaws of thinking that the final aim in software development is great stuff. Because the program looks lovely in the end, this approach makes it feasible to justify protracted development and release deadlines.

Teams Are Brought Together for Faster Product Delivery.

Another advantage of DevOps is that it allows other teams, such as operations, to benefit from working in an agile or iterative setting. Over the last decade, development teams have become more agile and have begun to create faster and faster.

Focuses on Development More Efficiently.

A massive release, which packs a lot of features into one deployment, or a rapid release, which rolls out features one by one, are the two ways to develop for a waiver.

End-to-End Accountability Is Supported.

In today’s economy, you must move faster and more precisely than your competitors to stay competitive. DevOps makes this possible by assisting your teams in focusing on the customer experience, uniting groups for faster product shipments, simplifying release goals, introducing automation (which reduces errors and frees up developer time for other projects), and establishing a feedback loop that benefits the entire company.


Using automated, integrated security testing technologies, you may use a DevOps approach without sacrificing security.

How Does DevOps Work?

Development and operations teams collaborate in a DevOps paradigm across the software application life cycle, from development and testing to operations and development.

DevOps is a process in which development and operations engineers collaborate throughout the project lifecycle, from development to design to maintenance and release.

The team collaborates to accomplish the desired result, from development and design to testing automation and continuous integration to continuous delivery. 

To respond quickly to client requests and handle bugs and defects, people with development and operations skill sets interact and employ CI-CD and monitoring tools.

What Is Driving the Adoption of DevOps Today?

Due to various macro factors in the software world, DevOps is rapidly gaining traction:

Hybrid Cloud With Software-defined Infrastructure

Data centers have undergone a significant transition in recent years, primarily due to cloud computing. The cost of putting up a data center in the pre-DevOps era was too high. 

Organizations struggled with fundamental tasks like scaling infrastructure since obtaining additional servers and configuring them took months. 

The Ops team had to manually run patches and updates on every system after building the data center, making updating even more difficult.

Requirements for Web-scale

Every company nowadays is a software company. 

The disruption of traditional business models by companies like Amazon, Netflix, and Uber has made SaaS the de facto manner of distributing software. 

As a result, technologies like mobile apps and interactive 

self-service portals have evolved from being systems of record to systems of interaction.

Architectures for Modern Applications

The shift to systems of engagement prompted software teams to think of new ways to handle scalability, be more agile in designing and deploying software, and manage cogs more efficiently. Microservices, a new application architecture, was born due to this. 

This method divides the application into small, decoupled parts called microservices that may be created, deployed, and scaled independently.


Containers have been there around for a while, but Docker gave them a considerable boost. Container use has gone from marginal to ubiquitous in just four years.

How To Adopt DevOps?

On the other hand, DevOps cannot be bought, registered, or proclaimed. If you’re considering switching to a DevOps distribution model, here are strategies for ensuring a successful DevOps adoption in your company.

DevOps does not begin with the declaration, “Let’s adopt DevOps,” and the implementation of tools. Your entire organization must understand what DevOps is and what kinds of business problems it can solve.

Choosing the right metrics to register and measure success is one of the most overlooked steps in DevOps implementation. DevOps does not have a “one size that fits all” approach. You can’t expect to succeed by merely using an automated program or hiring a self-proclaimed “DevOps Engineer.” Depending on their industry and experience, each company will take a distinct DevOps path.

Automation is the most critical factor in accelerating your delivery process. Everything from the infrastructure, environment, configuration, platform, and build through testing and the process should be described and implemented in code.

What Are the Challenges of Adopting DevOps?

Culture in Disarray

Workplace cultures that are commanding, controlling, and bureaucratic can be demotivating. People will stop sharing and contributing if they are penalized for highlighting issues if knowledge and information are secret.

Change Is Resistant

Many people dislike changing their working habits; they have grown accustomed to their current methods and frequently resist altering their customary routines or processes.

Lack of Vision Clarity

Many organizations want the benefits that DevOps promises, but they typically don’t devote enough effort to adequately preparing how DevOps will be implemented. Leaders may not have considered what DevOps would entail in an organizational reorganization, or they may be opposed to it.

Environments Are Not Uniform.

Dealing with the various application or service versions in a DevOps environment can cause production releases to be delayed and increase the number of bugs and issues in our products. Inconsistency leads to unpredictability; hence not having standard conditions or production-like test environments commonly results in accidents.


Q: What tools are used in DevOps?

Slack, Docker, Jenkins, Splunk, and other tools.

Q: What is the DevOps lifecycle?

The DevOps lifecycle involves phases that include continuous software development, integration, testing, deployment, and monitoring. A competent DevOps lifecycle is required to produce higher-quality software across the system.

Q: Is DevOps an agile methodology?

DevOps is an agile extension built around activities that aren’t covered but keep in mind that both methods improve software development and result in better products when applied together.
