Harness offers a Continuous Delivery Abstraction Model (CDAM) that simplifies cloud migrations by enabling businesses to switch services, infrastructure, and tools without rewriting deployment pipelines. This model supports various deployment strategies and cloud providers, facilitating efficient migrations such as lift-and-shift, re-platforming, and hybrid cloud architectures. Harness's approach allows for automation and integration, significantly reducing migration time and complexity, as demonstrated by a seamless migration that took only 76 minutes. By providing abstractions between services, infrastructure, and toolchains, Harness minimizes dependencies and improves velocity in deployment processes. The platform supports a wide range of artifacts, provisioners, cloud providers, verifications, secrets management, deployment, and notification strategies, making it possible to switch components without extensive reconfiguration. Since its launch, companies like Citi, SoulCycle, and Advanced Software have accelerated their cloud migrations using Harness CDAM, benefiting from enhanced portability, management, and scaling.
