• Developers write Components and GUI clients in Java, C++, or Python.• ACS provides an integrated build environment based on application code modules. • Communication from an application to a component, and among components, uses ACS as middleware.• No thinking about starting and stopping components, or on which machine they should run later.

Runtime
„container1“

p1“
• ACS containers start and stop components (“lifecycle management”) as needed.• containers provide components and clients with references to other components.• the “manager” is the central intelligence point that keeps the system together. Components never see it directly.•manager, CDB, and other services, are started with the “acsStart” command.

Container/Component evolution
• In recent releases we have improved decoupling of Components and Containers:– Full separation between Container and Container Services
• Cleaner interfaces• Easier to replace Container implementation
– Dynamic components– Tasks
• We have implemented automatic and dynamic deployment of Containers (ACS Daemon).
• Configuration of the runtime system is being discussed. We are working on better tools to keep aligned the configuration of the various ALMA deployments
