Azure Redis Patching Explained

Occationally customers will experience connection related errors in their client applications talking to Redis. Most often these errors are caused by one of the following:

Redis was patched or a master/slave failover occurred.
A client-side network configuration change was made. See below for details

In this article we will quickly discuss how patching works in Azure Redis and how this impacts clients. While this article talks mostly about patching, the experience is more or less the same when a failover occurs.

Best Practices for Azure Redis

Below are a set of best practices that I recommend for most customers. This information is based on my experience helping hundreds of Azure Redis customers investigate various issues.

Configuration and Concepts

Use Standard or Premium Tier for Production systems. The Basic Tier is a single node system with no data replication and no SLA. Also, use at least a C1 cache. C0 caches are really meant for simple dev/test scenarios since they have a shared CPU core, very little memory, are prone to "noisy neighbor", etc.
Remember that Redis is an In-Memory data store. Read this article so that you are aware of scenarios where data loss can occur.
Configure your client library to use a "connect timeout" of at least 10 to 15 seconds, giving the system time to connect even under higher CPU conditions. If your client or server tend to be under high load

	git submodule update --init --recursive

	One thing I ran into was having my configurations registered in the wrong order in my GLobal.asax file for instance:

	Right Order:

	AreaRegistration.RegisterAllAreas();
	WebApiConfig.Register(GlobalConfiguration.Configuration);
	FilterConfig.RegisterGlobalFilters(GlobalFilters.Filters);
	RouteConfig.RegisterRoutes(RouteTable.Routes);
	Wrong Order:
