An atomic service is a lightweight program provided by HarmonyOS. It is installation-free and features ubiquitous access, instant access, and free hopping. Independent of apps, an atomic service can be independently released, deployed, and executed to complete service closure.
Atomic services and apps are not mutually exclusive. Ecosystem partners can develop either or both of them to provide services for users. Developers can make decisions based on their operation objectives, efficiency, costs, and benefits.
