How AEM Works!

Adobe Experience Manager (AEM) is massive. There’s a lot of confusion when most developers and content editors come to this proprietary content management system. There are new terminology, processes and tools that one must understand. It can be overwhelming. Though it is impossible to write everything about AEM architecture in a single post, I wanted to write a post detailing some fundamentals for developers, but could still be read by anyone already working in AEM (using a language everyone can understand). So this is not a deep dive type of post. Understanding how AEM works will help you as a developer or author have a better insight into issues you may be having. My aim in the post is to give you the BIG picture. This is AEM architecture fundamentals.

AEM is a cloud based client-server system for building enterprise grade websites and applications. A copy of AEM running on a server is what you would normally hear of being referred to as an instance. The installation of AEM usually involve two instances running on separate machines on a production site. These is the author and the publish instances. Most of you know what the author instance is. This where you edit content. By editing content, i mean this is where you create, upload and management content on your website. Pretty much any website administration is done on the author instance (the name make sense since you are actually authoring content). Typically a content editor logs into AEM, edits or creates a page and either put their work in some kind of workflow for it to be approved, or perhaps they just publish the page when that content is ready (which goes live right away). What happens in the background, most of us don’t know. Here is where i want to shed a little light on because i feel knowing it gives you better insight into issues that might come up. Read More
