What is DevOps and Why Learn DevOps?

DevOps can be labeled as brothers in conflict or two faces of the same coin. It is the latest trend in software development, where programmers work in tandem with the operations team to make sure that the software program runs successfully with no glitches. Today, lots of software development teams are going the DevOps way, which is not only aiding organizations to handle the pressure to develop high-quality code but also helping them deliver faster.

According to Wikipedia, DevOps is a portmanteau of ‘development’ and ‘operations’ is a concept managing other points like software development, operations, and solutions. It highlights communication, collaboration, and integration between software developers and information technology (IT) operation employees. This 2019 Technical Skill Report explains the rise in demand for DevOps Certification.

Let us look at how Dev and Ops function:

  • Continual Changes
  • Include new attributes

Ops want:

  • Constant Stability
  • Create new solutions

The Trouble

In supplying useful software to consumers, usually, development and operations remain in conflict with each other. While development wants to deliver its modifications (for example, new functions) to clients promptly, operations want stability, which means not altering the manufacturing systems too often.

The gap between development and operations occurs on different levels:

  • The remuneration void: Results of different goals of development and operations.
  • The procedure gap: Results from different strategies of development and operations and how to handle the changes, bring them to production and maintain them there.
  • The tools gap: Results from the truth that development, and operations, typically use their tools to do their job.

Therefore, growth and operations frequently act like silos, as they are 2 unique teams.

Development and Operations in Conflict

  • Need for Change: Development results in change(as an example, new attributes, bug repairs, etc). It desires the changes to promptly roll out to production.
  • Fear for Change: Once the software program is delivered, the operations department avoids making changes to ensure the stability of the software.

Is DevOps the solution?
