for adopting a platform approach to software delivery. Here are some of the key reasons: Manage deployments from on-premise to cloud to edge 2 Scale infrastructure to meet demands 3 Enable built-in compliance Let's look at each of these reasons in detail. ## Benefits of the platform approach ### 1. Manage deployments from on-premise to cloud to edge As the infrastructure stack becomes more complex, what organizations Software Officer of the U.S. Air Force With GitOps, everything must be declarative, which means deployments are reliable and that any action can be replayed or rolled back at any time. Most of our teams

version control systems (VCS) like Git, GitLab, or GitHub. ## Fully Automated, Zero-Effort K8s Deployments with Rafay's GitOps Service Rafay's GitOps Service provides infrastructure orchestration deployment through multi-stage, git-triggered pipelines. With Rafay, enterprises increase the speed of deployments and improve the consistency of their K8s infrastructure. Multi-stage pipelines applying a variety eliminated application and cluster configuration drift and accelerated deployments by 4x." ## Fully Automated, Zero-Effort K8s Deployments with Rafay's GitOps Service Rafay's GitOps Service provides

production. b. Longer times between deployments accumulate larger differences and increased batch sizes c. Focus on reducing the friction with production deployments to be performed frequently and easily environment (begin practicing how to deploy to production in development) 2. Smoke testing our deployments – test connections to supporting services and systems, run sample data/transaction tests, fail ensure all environments are synchronized and consistent ### e. ENABLE AUTOMATED SELF-SERVICE DEPLOYMENTS i. As a result of compliance, oversight, and control needs separate Operations groups have emerged
