We're looking to upgrade some sites to take advantage of the new load balancing work in 7.3, specifically for Azure Web Apps. We currently have a single SQL Server database and Web App. Am I correct in saying that to get load balancing to work here we would need a second Web App to be the primary server from which to always access /umbraco?
If that's the case, how are any other servers aware of changes made on this server - new content/media for example? This was always the issue we had prior to 7.3.
Also, does it matter if, for example, our primary Web App is hosted in US East, but our secondary Web App is hosted in North Europe? Are there any problems with that, or is it a case of as long as the database is accessible from both it would work fine?
Thanks in advanced!
I stumbled upon this link yesterday, https://our.umbraco.org/documentation/getting-started/setup/server-setup/load-balancing/flexible
They made changes to load balancing as of 7.3.0.
I am in the process of setting up a separate backoffice instance also but I am pretty sure as long as they share the same db, it all works out.
Yes, I've also seen that documentation and it makes sense to follow it, I was just hoping for some sort of confirmation from someone that has previously successfully managed this that all content and media is nicely synced between all front-end Web Apps. I know the cache and Examine indexes are all local to a machine now, I just couldn't see any syncing method in place at this point.
You can use the new flexible loadbalacning in 7.3. You don't need to configure anything.
But all instances should point to the same database.
I would also recommend putting your media in Azure blob storage. There are several providers available for that. And maybe it's wise to have a CDN in place for all your regions
For example this one : https://our.umbraco.org/projects/collaboration/umbracofilesystemprovidersazure/
You can read some information about setting it up over here :
Especially read the part about configuring ImageProcessor to work with Azure blob storage.
Thanks so much for your response.
Would Umbraco 7.3 load balance correctly without putting media into blob storage?
So just to confirm - two Web Apps, one for /umbraco/ access, the other for front-end. And then the front-end one can be auto scaled by Azure without problems, and content/media is all synced automatically?
Haven't tried that approach. We always use the blob storage.
