Windows Azure Caching concepts

Microsoft Azure Cache is a family of distributed, in-memory, scalable solutions that enable you to build highly scalable and responsive applications by providing super-fast access to your data.Microsoft Azure Cache is available in the following flavors.– Azure Redis Cache (Preview) – Managed Cache Service – In-Role Cache

http://msdn.microsoft.com/en-us/library/gg278356.aspx#In_RoleCache

Managed Cache Service

Azure Managed Cache Service is based on the AppFabric Cache engine. It also gives you access to a secure, dedicated cache that is managed by Microsoft. A cache created using the Managed Cache Service is also accessible from applications within Azure running on Azure Web Sites, Web & Worker Roles and Virtual Machines. For more information

Using Managed Cache

// Cache client configured by settings in application // configuration file. DataCacheFactoryConfiguration config =

new DataCacheFactoryConfiguration("default"); DataCacheFactory cacheFactory = new DataCacheFactory(config); DataCache defaultCache = cacheFactory.GetDefaultCache();

// Put and retrieve a test object from the default cache. defaultCache.Put("testkey", "testobject"); string strObject = (string)defaultCache.Get("testkey");

In-Role CachingBased on the AppFabric Cache engine.

Allows you to perform caching by using a dedicated web or worker role instance in an application deployed to Microsoft Azure Cloud Services.

This provides flexibility in terms of deployment options and size but you manage the cache yourself.

//add string object to cache with key "Key0" myCache.Add("Key0", "object added with Key0");

//add or replace string object in cache using key "Key0" myCache.Put("Key0", "object replaced or added using Key0"); //remove object in cache using key "Key0"myCache.Remove("Key0");

Use Cloud Caching: the Right Reasons

Speed of access to dataAzure SQL databaseAzure storageRemote storage and servicesAvoiding hitting rate limitsUp to 5,000 entities/messages/blobs per second per accountUp to 500 messages per second from a single queueUp to 500 entities per second from a single table partition

Using Caching in your applications

Stores session state in shared memoryRequired for Web FarmsFaster than SQLSimple configuration change to your web app Enables session state to be cached across a clusterUses cache-aside, not RT+WB (session is Activity Data)TIP: Use HA to reduce the chances of sessions state loss

Example: ASP.NET App Session state provider

<sessionState mode="Custom" customProvider="SessionStoreProvider"> <providers> <add name="SessionStoreProvider“ type="Microsoft.ApplicationServer.Caching.DataCacheSessionStoreProvider,

Microsoft.ApplicationServer.Caching.Client, Version=1.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35“ cacheName=“MyCache"/> </providers></sessionState>

Azure Redis Cache (PREVIEW)

Microsoft Azure Redis Cache (Preview) is based on the popular open source Redis Cache. It gives you access to a secure, dedicated Redis cache, managed by Microsoft. A cache created using Azure Redis Cache is accessible from any application within Microsoft Azure.

Azure Redis Cache (Preview) is available in the following two tiers.

– Basic – single node, multiple sizes.

– Standard – Two node Master/Slave, multiple sizes. Once the preview period is over, the standard tier offering will have a 99.9% SLA.

Azure Redis Cache

Azure Redis Cache (use)using StackExchange.Redis;

ConnectionMultiplexer connection = ConnectionMultiplexer.Connect("contoso5.redis.cache.windows.net,ssl=true,password=...");

// connection referes to a previously configured //ConnectionMultiplexer IDatabase cache = connection.GetDatabase();

ConnectionMultiplexer connection = ConnectionMultiplexer.Connect("contoso5.redis.cache.windows.net..."); IDatabase cache = connection.GetDatabase();

// Perform cache operations using the cache object... // Simple put of integral data types into the cache cache.StringSet("key1", "value"); cache.StringSet("key2", 25); // Simple get of data types from the cache string key1 = cache.StringGet("key1"); int key2 = (int)cache.StringGet("key2");
