DevOps owes its origins to the level of dysfunctionality that traditional software development systems caused which kept the people who actually code and those who deploy those codes in silos.
The snowball effect of the chaos that ensued led to isolated teams with competing goals, long hours, botched releases and ultimately unsatisfied customers.
DevOps started off as a discussion on online forums has now turned into a movement with organizations creating their work culture around it.
Interesting right? Let’s understand what devops actually is before we dive into the reasons to learn it.
What is DevOps?
A combination of word development and operation, DevOps brings together the application development and IT operations team with an aim to promote better collaboration and communication.
While that is a broader brush stroke to define what a DevOp is but for all practical purposes, DevOps is a combination of many techniques and can be visualized in the form of an infinite loop consisting of following steps:
- Feedback which resets the loop
Common Methodology to build an environment for devOps
- CI/CD tools ( continuous integration, delivery and deployment) and task automation
- Systems and Tools like incident management, configuration management and collaborative platforms to facilitate DevOps adoption
- Implementing cloud computing, microservices and containers in addition and to support DevOp methodologies
The approach is to align software expectations by bringing together the developers and stakeholders to communicate about the project. The developers then go on to make small changes that go live independently.
And the continuous integration and continuous deployment methodology is used to move code from one phase to another, changes are reviewed immediately and policies are enforced to ensure the release meets the desired standards.
Getting those codes deployed without a drama is a dream most developers have; however despite opting for agile methodologies and extensive planning, that dream remains elusive. And DevOp is that magical wand that promises to fix everything by one wave or not but there is no need to roll your eyes before you take a look at the data.
Atlassian conducted a survey with 500 devop practitioners as participants and discovered that 99% of the devop team showed confidence regarding the success of their codes going into production. Now that’s optimistic.
So what are the advantages of adopting DevOps?
Advantages of DevOps
- Shorter Development Cycle – There is no denying that frequent communication between various stakeholders results in shorter deployment time. With combined efforts of the development and operations team the turnaround time for development cycles is considerably shortened. A shorter development cycle helps bring a product to market 60% faster than the traditional methods.
- Minimized deployment failure, rollbacks and recovery time – DevOps ensure frequent code releases which makes spotting defects easier. Agile programming principles achieved through collaboration and modular programming, the number of deployment failures can be considerably reduced. While failures are expected, recovery time reduces if the teams are frequently communicating and exchanging ideas, suggestions and feedback
- Improved Communication and Collaboration- The means and the end too, DevOps environment has a long term effect on the way teams function together for software development. The collaborative approach towards collective goals help in minimizing inter team conflicts and allows scope to innovate.
- Increased Efficiency- When resources are optimized and processes automated, it results in an accelerated development process with reduced risk of errors. With the availability of acceleration tools like cloud based platforms, scalability on demand is possible. Parallel workflows and a single environment for development, testing and deployment are other add on benefits.
- Reduced Cost- DevOps team requires fewer IT staff and therefore has lower IT cost.
Skill Sets to Acquire for a Career in DevOps
- Programming languages (Python, Ruby, Rust, Node.js, etc.)
- Concepts of OS
- Understanding version control systems
- Managing servers
- Linus Concepts
- Web Server Concepts
- Infrastructure as a code
- Configuration of software
With a proven record of reducing application development cycle, increased innovation , stable operating environment and collective effort towards shared goals makes DevOps a promising solution for businesses. With more and more companies adopting it the market itself is expected to reach US$ 287.9 billion by 2026.
While it means more revenue for the company it also means more job prospects for devop professionals. A win -win for all.
