The Scalability Problem

Application Tier Scales Linearly

BUT

Data Storage is the Bottleneck(Relational Databases, Mainframe Data, etc.)

NoSQL Database Not Always the Answer(cannot always replace relational DB)


The Solution

In-Memory Distributed Cache (NCache)

(Makes other databases faster and scalable)

Use it with

Relational DatabasesLegacy Mainframe Data

NoSQL Databases


Distributed Cache Deployment (NCache)


Common Uses of a Distributed Cache

1. App Data Caching– Cache linearly scalable (database is not)– Data exists in BOTH cache & database (permanent data)

2. ASP.NET Specific Caching– ASP.NET Session State storage (single-site & multi-site)– ASP.NET View State cache– ASP.NET Output Cache provider– Data exists ONLY in cache (transient data)

3. Runtime Data Sharing thru Events– Event driven data sharing in pub/sub model– Event notifications & Continuous Query– Data exists ONLY in cache (transient data)


NCache is:

• The oldest .NET distributed cache in the market• 100% native .NET integrated into the .NET stack• Open Source under Apache 2.0 License• Latest version, 4.6, is 12th version• Alachisoft is MS 2012 certified• NCache has an AppFabric Wrapper• Check out the following comparison to Redis


NCache vs Redis

Platform & Technology


NCache

•Open Source– Apache 2.0 License

•Windows (100% .NET)– Developed in C#– Windows Server 2012 R2 Certified

•.NET Client (officially)

•Java Client (officially)– Same socket protocol as .NET

client– Runs on Windows & Unix

NCache vs RedisPlatform & Technology

Redis

•Open Source– BSD License

•Linux (Redis Labs)

•Windows (MS Open Tech)– Open Source and unsupported– Buggy and unstable– Even Azure uses Linux version

•.NET & Java Clients (3rd Party)– Unsupported


NCache

•On-Premises (Windows)– Perpetual License (own it)– Annual maintenance (optional)– 24x7 support (optional)– Open Source is FREE. Use as is

NCache vs RedisOn-Premises Support

Redis

•On-Premises (Linux)– By Redis Labs– Annual subscription– Open Source. Use as is.

•On-Premises (Windows)– By MS Open Tech– Buggy, unstable, & without

support– Even Azure uses Linux version


NCache (VM Model)

•Control Cache Server VMs– Login and control/administer

•Run Server-side Code– Read-thru, Write-thru, Write-

behind– Cache Loader, Custom

Dependency– MapReduce, Aggregator, Entry

Processor

•Azure, Amazon, and others– Cloud licensing (hourly charges)

NCache vs RedisCloud Support

Redis (Service Model)

•No Access to Cache Server VMs– Only client-side API access

•Azure (Microsoft)– Azure uses Linux version of Redis– Cloud licensing (hourly charges)– No access to cache servers– Cannot run server-side code

•Amazon & others (Redis Labs)– Only Linux version


NCache vs Redis

Architecture


NCache

•Extremely fast & scalable– Client/Server communication

•Client Cache (even faster)

•Bulk Operations– Reduce trips to caching tier– Works on the entire cache

•Fast Compact Serialization– 10 times faster

•Compression

NCache vs RedisPerformance & Scalability

Redis

•Fast & scalable (Linux version)– Windows version has issues

•Bulk Operations– Works on one shard only

•Slow Serialization– APP must convert all data to

STRING


NCache: Client Cache (Near Cache)

NCache

•Dynamic Cache Cluster– Add/remove nodes seamlessly

•Dynamic Configuration– Apply to the entire cluster

•Cluster Health Events– To automatically handle things

•Split Brain Detection– No recovery provided yet

NCache vs RedisHigh Availability (100% Uptime)

Redis

•Cluster Not Fully Dynamic– Cannot auto add/remove Shard– Cluster stops if Shard is down

•Dynamic Configuration (Partial)– Manually apply to each server

Without stopping anything

Connection Failover Support Between clients & servers Within cache cluster

NCache

•Local Cache/Client Cache

•Mirrored Cache

•Replicated Cache

•Partitioned Cache

•Partition-Replica (Async/Sync)– Sync: for really sensitive data

•Data Balancing (Partitioned)– To automatically redistribute data

NCache vs RedisCache Topologies

Redis

•Local Cache (OutProc Only)

•Partitioned Cache– Cannot auto-handle shard down

•Partition-Replica (Async only)– Cannot auto-handle shard down – Cannot handle sensitive data– May lose data on replication

NCache

•2 Data Centers (Active/Passive)– Async replication (queue based)– Auto reconnect sockets

•2 Data Centers (Active/Active)– Handle conflicts on “last update

wins” – Custom conflict resolution handler
