"Before DevOps, many organizations were stuck in a cycle of slow releases and siloed teams. Developers would work in isolation for months before handing code off to QA and operations teams for deployment. This adversarial approach to software development hindered innovation within organizations such as Amazon, Netflix, and Google until they adopted a DevOps approach."
"DevOps eliminates blame games in favor of shared responsibility. This allows teams to deploy faster, resolve defects in a timely manner, and improve product quality. For business resiliency, this is a crucial cultural shift because it allows teams to respond to issues rather than throwing them "over the wall" to resolve."
"DevOps also allows teams to innovate faster through a microservices approach to software development. This means that an application is broken down into many small services, where each service is maintained by a small team. Each of these services also talks to other services through APIs. This allows teams to innovate faster and makes applications more flexible. However, this also requires teams to ensure that there is proper automation to avoid a reliability nightmare from all these services."
Business change drives a need for resilience: adapting, overcoming disruption, and continuing to create enterprise value despite shifting customer demands, new competitors, and rapidly evolving cyber threats. DevOps unifies software development and operations to replace slow, siloed release cycles with shared responsibility. This reduces blame and enables faster deployment, timely defect resolution, and improved product quality. DevOps also supports microservices, breaking applications into small services owned by small teams and connected through APIs, which increases flexibility and innovation speed. Microservices require strong automation to prevent reliability problems. Continuous integration and continuous delivery/deployment further accelerate delivery by enabling frequent, repeatable software releases.
