»Under a DevOps model, development and operations teams are no longer “siloed.” Sometimes, these two teams are merged into a single team where the engineers work across the entire application lifecycle, from development and test to deployment to operations, and develop a range of skills not limited to a single function. and security teams may also become more tightly integrated with development and operations and throughout the application lifecycle.
»These teams use practices to automate processes that historically have been manual and slow. They use a technology stack and tooling which help them operate and evolve applications quickly and reliably. These tools also help engineers independently accomplish tasks (for example, deploying code or provisioning infrastructure) that normally would have required help from other teams, and this further increases a team’s velocity.
Here are some DevOps benefits:
- Speed: Move faster as a team so there will be more product produced
- Quality: Develop higher quality products with faster feedback loops resulting in continuous quality deliveries
- Collaboration: Smaller teams work more efficiently together and eliminate organizational silos
- Scale: Manage development and infrastructure leveraging automation to accelerate productivity
- Security: Using a DevOps model companies can ensure security compliance
