ACA Express Apps are ideal for teams prioritizing rapid deployment, such as startups and internal platform groups. They are designed to quickly ship APIs, web apps, or agent endpoints that handle fluctuating demand. The primary benefits are a fast path to production, predictable wake-up times, and minimal infrastructure overhead. A live demo shows Express apps starting from zero in approximately 1.5 seconds, compared to 20 seconds for traditional Consumption environments. This speed is achieved through MicroVMs that enable fast, secure startup and isolation. State restoration, which preserves disk and memory, significantly reduces the need to rebuild runtime on every wake-up. This allows for practical scale-to-zero functionality with low wake-up penalties. The deployment process is simplified by eliminating environment setup, allowing teams to ship containers directly. Creating an Express app involves a simple form without the need to stand up infrastructure first. Measurements indicate Express is significantly faster for initial setup and cold starts. Once an environment exists, deployment times are comparable. Express apps are currently in public preview, with resources available for getting started. When swift deployment is critical, ACA Express offers a powerful solution for containerized applications.
