What is DevOps?

Even as the adoption of DevOps in large companies and native web organizations continues to accelerate, the exact meaning of the term remains unclear. Does this means  DevOps is a culture, a movement, an approach, a philosophy, or an amalgamation of many of these things? Or DevOps means different things to different people?

Regardless of how DevOps is defined, DevOps success undoubtedly requires a journey. Here we can help you answer several basic questions, including:

  • What is DevOps?
  • Where does it come from?
  • What issues led to the creation of DevOps?
  • How does DevOps “work”?
  • How widespread is DevOps today?

1. What is DevOps?

The word “DevOps” was invented in 2009 by Patrick Debois, who became one of its mentors. The term was formed by uniting “development” and “operations”, this provides a starting point for understanding exactly what people generally mean when they talk about “DevOps”.

 2. Where does DevOps come from?

Notwithstanding the fictitious tone of some of the stories about its origination, DevOps was not designed from scratch. Instead, the seeds of DevOps have long been planted and cultivated by forward-thinking IT professionals across multiple disciplines. The two main sources of DevOps are:

  • Enterprise System Management (ESM). Most of the people associated in the initial denotation of DevOps were system administrators. These operations experts usher key ESM best practices to DevOps, including system monitoring, configuration management, toolchain approach, and an automated provisioning.
  • Agile development. One looker on can notice that “DevOps can be explained as an outgrowth of Agile: Agile software development necessitates very close cooperation between customers, product management teams, developers teams, and quality assurance teams in order to fill the gaps and quickly recapitulates toward a product better… [DevOps recognizes that] service delivery and how the application and systems interact is also a critical part of the customer value premise and therefore the product team must consider these worries as a top-level element from this perspective, DevOps simply holds out agile principles beyond the limits of code to the entire service provided.

3. What issues led to the development of DevOps?

Developers and system administrators don’t always agree on several things, but they do agree that their customers on the business side of the house often haul them in different directions. On the one hand, business users demand changes as quickly as possible (new features, new services, new revenue streams).

At the same time, they also want a stable system, free from crashes and interruptions. This creates an issue where organizations feel they have to choose between making quick changes and dealing with an unstable production environment or maintaining a stable but outdated environment.

Developers are ready to release software faster and faster. That’s what they’re usually hired for. On the other hand, companies know that quick changes without proper security precautions can destabilize the system, which directly violates its statute.

DevOps is designed to solve this dilemma by integrating everyone involved in software development and deployment (business users, developers, test engineers, security engineers, system administrators, and sometimes others) into a sole, highly automated workflow to deliver high-quality software that reaches all user needs while maintaining the integrity and stability of the entire system.

How do these different groups join forces? Signing a common set of principles that transcend the traditional boundaries and functions of disciplines, for example:

  • Establish the expectations and priorities and the basic beliefs that guide them.
  • Collaboration within and between teams in problem-solving.
  • Automate common, repetitive processes to free up time for higher-level tasks.
  • Include feedback at work and measure everything that goes into production.
  • Share data with everyone involved to foster a more effective culture of collaboration across different skills and expertise.

4. DevOps, Agile, and SRE explained

Agile and Lean are how teams iterate, with short development cycles and quick feedback. Agile focuses on culture and doesn’t know what tools are being used.

DevOps is how engineering organizations work with cross-functional teams. DevOps starts with culture and goes all the way to tooling.

SRE (System Reliability Engineering) is how engineering organizations automate and deliver large-scale operations for people with a software engineering mindset. SRE starts with tools and moves towards culture.

The insertion or addition of another organization/practice earlier in the software development lifecycle (SDLC) can be counted in Types of DevOps, and the escalation of these different types of DevOps is proof of the increasing integration of functionality in modern organizations.

5. How does DevOps “work”?

Like all cultures, DevOps also have many variations on the theme. However, most observers would agree that the following skills are common to virtually every DevOps culture: collaboration, automation, continuous integration, continuous deployment, continuous testing, continuous monitoring, and rapid problem resolution.
