What is MSM in AEM?

 MSM (Multi-Site Manager) in AEM helps manage multi-country or multi-language websites by creating a master site (Blueprint) and synchronized copies (Live Copies). Updates done in the master can be rolled out to all child sites automatically. It saves time, maintains consistency, and allows local variations.

MSM (Multi-Site Manager) in AEM is a feature used to manage multiple websites that share similar content, structure, and design.

It helps you:

  • Create master content (Blueprint)

  • Copy it automatically to multiple country/region sites (Live Copies)

  • Keep all sites synchronized with consistent updates

📌 MSM Basic Terms

TermMeaning
BlueprintMain/master site that contains the original pages
Live CopyChild site created from the blueprint
RolloutPush changes from blueprint → live copies
InheritanceLive copy follows the blueprint updates

🌍 Real Example to Understand MSM Easily

🔹 Suppose you manage a global website:

Main site (Blueprint):

www.company.com

You need to create websites for 3 countries:

www.company.com/us
www.company.com/uk
www.company.com/in

Instead of creating each site manually, you can:

✔ Step 1: Create main/master site as Blueprint

Contains:

  • Header

  • Footer

  • Homepage

  • Products

  • About Us

  • Contact

✔ Step 2: Create Live Copies for each country

US site → Live Copy
UK site → Live Copy
India site → Live Copy

✔ Step 3: Update content in the master site and Rollout

Example: You update the “Products” page in Blueprint.

After rollout:

  • US “Products” page updates automatically

  • UK “Products” page updates automatically

  • India “Products” page updates automatically

This is MSM!

📌 MSM Example Scenario

🧩 Example: Launching a new product globally

You add a new banner on the master homepage.

Using Rollout:

  • US homepage gets the banner

  • UK homepage gets the banner

  • India homepage gets the banner

You updated once → all country pages updated.
