NCache vs Redis: What are the differences?


In this article, we will discuss the key differences between NCache and Redis. NCache and Redis are both popular in-memory distributed caching solutions, but they have some fundamental differences in terms of architecture and features.

  1. Scalability: NCache offers horizontal scalability by distributing the cache across multiple servers, making it highly scalable for high-volume applications. On the other hand, Redis provides scalability through replication, where data is replicated across multiple instances, but it does not support direct horizontal scalability.

  2. Data Persistence: NCache provides built-in support for data persistence, allowing cached data to be stored permanently on disk. This ensures data durability even in case of server failures. Redis, on the other hand, relies on asynchronous disk writes for persistence, which may result in data loss in case of unexpected failures.

  3. Data Structure Support: Redis is known for its extensive support of various data structures, such as strings, lists, sets, hashes, and sorted sets. It also provides a rich set of operations to manipulate these data structures. NCache, on the other hand, primarily focuses on key-value caching and does not offer the same level of support for complex data structures.

  4. High Availability: NCache offers high availability through features like synchronous replication, failover, and automatic data backup to ensure uninterrupted access to the cache. Redis, on the other hand, relies on asynchronous replication and lacks built-in failover mechanisms, which can result in some downtime during failover scenarios.

  5. Cache Management: NCache provides a user-friendly GUI-based management tool, which allows administrators to monitor and manage the cache cluster easily. It also provides features like cache monitoring, cache statistics, and real-time alerts. Redis, on the other hand, does not offer a built-in GUI for cache management and relies on command-line tools or third-party management tools.

  6. Integration with Microsoft Ecosystem: NCache is specifically designed for the .NET ecosystem and provides tight integration with Microsoft technologies, such as ASP.NET, ADO.NET, and Entity Framework. It also supports distributed caching of session data for ASP.NET applications. Redis, on the other hand, is a more platform-agnostic solution and provides client libraries for various programming languages.

In Summary, NCache and Redis have key differences in terms of scalability, data persistence, data structure support, high availability, cache management, and integration with the Microsoft ecosystem.

      What is NCache?

      NCache is an open source distributed cache for .NET & .NET Core (Apache 2.0) by Alachisoft. NCache provides an extremely fast and linearly scalable distributed cache that caches application data and reduces expensive database trips.

      What is Redis?

      Redis is an open source (BSD licensed), in-memory data structure store, used as a database, cache, and message broker. Redis provides data structures such as strings, hashes, lists, sets, sorted sets with range queries, bitmaps, hyperloglogs, geospatial indexes, and streams.

      What are some alternatives to NCache and Redis?
      Memcached is an in-memory key-value store for small chunks of arbitrary data (strings, objects) from results of database calls, API calls, or page rendering.
      With its various distributed data structures, distributed caching capabilities, elastic nature, memcache support, integration with Spring and Hibernate and more importantly with so many happy users, Hazelcast is feature-rich, enterprise-ready and developer-friendly in-memory data grid solution.
      Developed as an alternative to traditionally inflexible SQL databases, the Couchbase NoSQL database is built on an open source foundation and architected to help developers solve real-world problems and meet high scalability demands.
      MongoDB stores data in JSON-like documents that can vary in structure, offering a dynamic, flexible schema. MongoDB was also designed for high availability and scalability, with built-in replication and auto-sharding.
      JavaScript is most known as the scripting language for Web pages, but used in many non-browser environments as well such as node.js or Apache CouchDB. It is a prototype-based, multi-paradigm scripting language that is dynamic,and supports object-oriented, imperative, and functional programming styles.
