API Gateway supports staging and promotion of assets. In a typical enterprise-level, solutions are separated according to the different stages of Software Development Lifecycle (SDLC) such as development, quality assurance (QA), and production stages. As each organization builds APIs for easy consumption and monetization, continuous integration (CI) and continuous delivery (CD) is an integral part of the solution. Where, CI is a development practice that requires developers to integrate code into a shared repository several times a day and CD is a software engineering approach in which teams produce software in short cycles, ensuring that the software can be reliably released at any time. Development of assets starts at the development stage and once the assets are developed, they are promoted to the QA stage for testing, after testing of the assets is complete, the assets are promoted to the deployment stage.

API Gateway provides tools and features to automate your CI and CD practices. Modifications made to the APIs, policies, and other assets can be efficiently delivered to the application developers with speed and agility. For example, When you publish new applications, the API definitions change. These changes are to be propagated to application developers. The API provider has to update the associated documentation for the API or application. In most cases this process is a tedious manual exercise. You can use API Gateway staging and promotion to address such cases to automate API and policy management that makes deployment faster, introduces continuous innovation with speed and agility. This ensures that new updates and capabilities are automatically, efficiently, and securely delivered to their developers and partners, in a timely fashion and without manual intervention.
