Career Prospects in DevOps

DevOps is a recent innovative approach in the Software Development process where developers and deployment operations teams in an IT organization collaborate and work together throughout the overall Software Development Life Cycle (SDLC). Prior to the integration of DevOps, IT companies often used the Waterfall or Siloed development methods, which extended the development cycle significantly. These methods made it difficult for the teams to collaborate and communicate effectively.

The Siloed development approach results in chaos, confusion, and disputes between the teams during the SDLC, leading to delayed deployments. The lack of synchronization between the teams often delayed the product development cycle. Even when software was produced, it frequently contained errors or faults, failing to deliver fault-tolerant applications. The root cause of these issues was the need for more communication and collaboration within the organization.
