Lack of SSI in AEMaaCS Dispatcher

[Tomasz_Sobczyk]

Reading through the docs for AEM as a Cloud Service for Dispatcher. Obviously there are a lot of limitations imposed there (still working through the "this won't be possible anymore" effects of it. One thing that struck me was this:
https://experienceleague.adobe.com/docs/experience-manager-cloud-service/implementing/content-delive...

It seems that the Cloud's Dispatcher doesn't include BASIC! things like support for Server Side Includes... Are there any plans in place to improve this? The docs vaguely mention that in future it could potentially include more modules.... What's the reasoning for not having something as basic as SSI (paired with for example SDI)

Hi,

I am no expert on AEMaaCS but what I think is the reason for not including everything to AEMaaCS because AEMaaCS is just not a migration to the cloud it is more. e.g. using microservices to do offline processing for assets, changing replication, etc.

There is a lot of feature from traditional AEM has been removed e.g. Campaign, Product etc. and getting added gardually.

But you can expore https://sling.apache.org/documentation/bundles/dynamic-includes.html to implement SSI in AEMaaCS if it is not available OOTB.

HI Arun, I think you missed the point here a bit. The bundle you mentioned will work ok on AEM as a Cloud. BUT! There is Apache bit to it - a dedicated module needs to be enabled on Apache to get Server Side Includes to work (or alternatively ESI could be turned on in Fastly). None of those currently works on AEM SaaS - which effectively means that it's IMPOSSIBLE right now to do ESI/SSI on what Adobe provides for AEM SaaS. The only option to achieve this right now from what I understand is to set up your own CDN/HTTP server in front of AEM as a Cloud infrastructure and resolve ESI/SSI there - this means extra infra which kind of defeats the purpose of AEM SaaS being a ready to use offering 🙂

I think, this does work now. I checked with local sdk and dispatcher setup. Changes are below

Hi,

When I check the list of allowed Apache modules I don't see mod_include there

So I assume that it's not supported correctly when deployed to cloud. Did you test it on an actual cloud instance (local SDK is quite far away from the actual thing).

Hi @Tomasz_Sobczyk 

I did not test this on actual cloud since I don't have any sandbox to test this.

but I tested on dispatcher docker image provided by adobe
