DevOps — History and Evolution

Before DevOps, development teams and operations teams worked separately, which caused delays and miscommunication. Developers built software without fully understanding deployment challenges, while operations teams struggled to maintain stability during updates. This led to slower release cycles and more production issues. Agile methodology helped developers work faster, but deployment remained a challenge. DevOps emerged around 2009 to bridge this gap, emphasizing collaboration, automation, and continuous delivery.

Example: Agile focuses on development speed, while DevOps extends it to include deployment and operations.
