AEM Dispatcher module

[deepakt84913413]

Our website has Akamai for caching and F5 for load balancing. Do I still need the dispatcher module? what are the benefits?

Hi,

the dispatcher has a few roles in an AEM deployment:

• Caching layer: Even if you have a CDN the dispatcher can still help to reduce load on publish; typically you run the CDN with TTL-based expiration with a interval to cater worst cases (e.g. 10 minutes). But the dispatcher helps you to reduce the load, because your pages do not change every 10 minutes.
• Security: The dispatcher is an integral part of the AEM security checklist.
• Architecture: Any web architecture requires an additional webserver layer in front of the application servers ( = publishs).
