Getting Started with Azure Redis Cache (1)

Windows Azure Platform Family of articles Catalog

Microsoft Azure Redis Cache is based on the popular open source Redis cache.

1. function

Redis is an advanced store of key values where keys can contain data structures such as strings, hashes, lists, collections, and ordered collections. Redis supports a set of atomic operations on these data types.

Redis also supports setting up simple master-slave replication, with very fast non-first-stop synchronization, automatic reconnection when network segmentation, and so on.

Other features include transactions, publish/subscribe, Lua scripting, keys with limited time-to-live, and configuration settings that make Redis behave like a cache.

You can use Redis in the most commonly used programming languages today.

Azure Redis Cache leverages Redis authentication and also supports SSL connections to Redis.

　　

2. Reusable

　　Compared to the author's previous written documents:

Windows Azure Cloud Service (44) uses Azure In-role cache caching (1) co-located Role

Windows Azure Cloud Service (45) uses Azure In-role cache caching (2) dedicated Role

The In-role cache above will only be available for cloud service deployment, if the newly created cloud service project wants to share is not possible.

After we create Azure Redis cache, this Redis cache is shared, and one or more azure application can use this azure Redis cache

3. Service level

Microsoft Azure Redis Cache is divided into two levels:

(1) Base (basic)-a single node. Available in different sizes. There is no SLA for the basic mode.

(2) standard-Two-node, master-slave mode. Includes SLAs and support replication. Available in various sizes.

(3) Advanced (Premium)-Enterprise-class caching service. Designed for large-scale concurrency.

Azure Redis Cache offers the following different service levels:

Basic (Basic, does not include SLAs):

Cache Name	Cache size	Network performance	Number of client connections
C0	250MB	Low	256
C1	1GB	Low	1000
C2	2.5GB	Medium	2000
C3	6GB	Medium	5000
C4	13GB	Medium	10000
C5	26GB	High	15000
C6	53GB	Highest	20000

　　

Standards (Standard, SLA support):

Cache Name	Cache size	Network performance	Number of client connections
C0	250MB	Low	256
C1	1GB	Low	1000
C2	2.5GB	Medium	2000
C3	6GB	Medium	5000
C4	13GB	Medium	10000
C5	26GB	High	15000
C6	53GB	Highest	20000

　　

Premium (Premium):

Cache Name	Cache size	Network performance	Number of client connections
P1	6GB	Medium	7500
P2	13GB	Medium	15000
P3	26GB	High	30000
P4	53GB	Highest	40000

　　

4. High Performance

Azure Redis Cache helps your application become more responsive (even as the user load increases), and leverages the low latency, high throughput capabilities of the Redis engine. This separate distributed cache layer allows the data tier to scale independently to make more efficient use of compute resources in the application tier.
