The DevOps is basically a Software development system and most popular in Cloud computing. On-device software and storage may not be passe just yet, but it’s getting there, as more and more computing processes are taking place in the cloud. 



Many companies are also preferring distributed computing, which allows multiple computers to network with one another to solve a task (and, unlike the cloud, gives companies control over the actual hardware involved).

Many of the skills involved with cloud computing and distributed computing are related, so the two are often grouped together:

Skills to learn include SQL for database management, programming languages like Ruby, JavaScript, and Python for building cloud-based applications, and DevOps (a software development system popular in the cloud computing field). Specific in-demand programs include Microsoft Azure and Amazon Web Services.
