Development goals
• Application should autoscale• Use core/community functionality where possible • Focus on performance• DRY backend and front end• 1-1 multilingual for reusable content

ITS 03Load balance setup
• Hosted on Azure (Blob storage / redis cache)• VM with editors environment (master)• Front end runs on auto scaling web app (slaves)• Started on 7.3 beta because of the flexible loadbalancing
(no config for loadbalancing needed)• But you need to have some config tweaks. So make sure
you read the loadbalancing docs on our.umbraco.org
LOADBALANCED

LOAD
BALA
NCE
D • Use correct events to update custom cache (e.g. output cache)
• Published event is only executed on the server where it’s triggered. Not on all other servers.
• Hook in to CacheRefreshers CacheUpdated event instead. PageCacheRefresher.CacheUpdated += (sender, args) =>{ { // clear cache here };

LOAD
BALA
NCE
D • For custom needs it’s possible to create your own cache refreshers .
• Need to create a class that implements ICacheRefresher interface.
• Umbraco has some base classes that you can inherit from like CacheRefresherBase and JsonCacheRefresherBase
• When your data is changed tell the distributed cache that it needs to execute a method on the cacherefresher :
• DistributedCache.Instance.RefreshAll(CustomCacheRefresherGuid);
• And handle the CacheUpdated event for the cache refresher

Database access
• Goal was to do database maintenance (creating, modifying tables) from code so that it becomes part of the automated build process.
• We’re using uSync for all Umbraco parts.

07Pluginmanager
Whenever types need to be found in assemblies in order to add them to resolvers, the PluginManager should be used. The TypeFinder should never be used directly in any code except for in PluginManager extension methods or in the PluingManager itself.• PluginManager.Current.ResolveTypes<T>• PluginManager.Current.ResolveAttributedTypes<T>()• PluginManager.Current.ResolveTypesWithAttribute<T,S>
