What is DevOps, and how to become a DevOps engineer?

Businesses have no choice but to adapt to an evolving business and technology environment. There are software version releases that which entirely focuses on favoring business processes and enhanced output. Project management technologies such as Agile and Scrum helps in the continuous iteration of development and testing in the complete software development and life cycle process. The development and testing activities are concurrent here, thereby encouraging teamwork and face-to-face communication among the engineers. DevOps is the next development in this changing environment. 

It is the new buzzword in the IT field; people with DevOps skills are in a lot of demand because businesses are now able to leverage continuous delivery.  Let’s explore what DevOps, what DevOps engineers do, and how one can build careers in this space. Understanding DevOps can be straightforward- it is a combination of software development techniques that combine both software development (Dev) and IT operations (Ops). Now, this proceeds to enable the delivery of features, bug fixes, and updates frequently – all of which are aligned with business demands. In other words one can easily say that DevOps cuts down the software development life cycle timeline.

While both DevOps and agile can seem similar, the fact is while Agile bridges communication gap between customers/stakeholders and developers, while DevOps gets down to together developers and IT operations/infrastructure. DevOps focuses on the deployment of the software developed agnostic of the methodology involved.

What are the components of DevOps?

Continuous integration and continuous delivery are the most vital aspects of DevOps. The former is a software strategy that enables organizations to deliver new features to users as fast and as efficiently as possible. The core idea here is to create a reliable, repeatable, incrementally improving process to take software from concept level to selling. The goal is to seamlessly allow a constant flow of changes into production via an automated software production. The delivery pipeline is what makes it all happen.

DevOps processes- this includes the regular software life cycle steps in the following order-
  • Code development and review, source code management, and merging codes.
  • Continuous integration tools and build status.
  • Testing tools that provide feedback on business risks.
  • Artefact repository and application pre-deployment staging.
  • Management of changes required release approvals and release automation accordingly.
  • Infrastructure configuration and management, along with relevant tools.
  • Monitoring performance of the application and end-user experience.

Educational qualifications for a career in DevOps-

Strength in the concepts of the software development life cycle, including development basics and automation testing fundamentals are a must. To proceed further along the same lines, there are some certificate courses available that can be pursued-

A foundation course in DevOps with the following learning objectives-
a. DevOps objectives.
b. Benefits of the technology to itself and the business.
c. Relationship between DevOps/ Agile and Scrum.
d. Improved workflows and communication
e. Automation practices including deployment pipelines

Who is an ideal DevOps engineer?

Over and above day-to-day regular DevOps skills, to make a mark in this domain, it is crucial for the following additional skills as well-

  • He or she must be flexible since coding is an ever-changing and continuous process, where the ability to learn and adapt is essential.
  • DevOps operates on a shorter cycle of code development and deployment and hence is vulnerable to security threats. There must be no compromise on security levels; therefore.
  • A DevOps engineer should work collaboratively within a team, making the process cross-functional.
  • Well it is but a mandate that you must know how to code in different programming languages, such as JavaScript, PHP, Python, but one must also know how to write code automatically assign IP addresses or DNS codes.
  • The whole point of faster deliveries relies on the ability to make critical decisions within a short period with minimal iterations or changes.
  • Understanding the right infrastructure, along with depth and challenges associated with it will enable a DevOps engineer to design and deploy applications effectively using the best possible platforms.

The development team that adapts into this system of continuous integration lend themselves an edge- they depend on smart, automated processes that are capable of producing the best possible applications that they can. A system that standardizes their coding, their testing, and their other activities such that the final product contains secure, efficient, robust, and reliable code. This can save businesses a lot of time- unarguably the most invaluable resource on hand.
