OSGi Deep Dive Series - Complete Overview

Overview

Over the past few weeks, I’ve been writing a detailed OSGi series aimed at understanding how OSGi really works under the hood, especially in the context of platforms like Adobe Experience Manager (AEM).

OSGi Container – The Heart of the System

Understand how the OSGi container manages bundles, services, lifecycle, and enables zero-downtime updates.

Bundles, Bundle Metadata & Classloading

Learn what makes a JAR an OSGi bundle and how manifest metadata drives modularity and bundle-level classloading.

Bundle Lifecycle, Activator & Service Registry

Explore bundle states, lifecycle transitions, the role of the BundleActivator, and how services are registered and managed at runtime.

Inversion of Control (IoC) & Dependency Injection (DI) in OSGi

Learn how OSGi achieves loose coupling and dynamic wiring using services.

Components, Services, Declarative Services (DS) & SCR

See how components are managed, services are exposed, and how SCR powers Declarative Services behind the scenes.

This series focuses on conceptual clarity - not just how to configure OSGi, but why it works the way it does.
