Learn about NCache caching technology

As modern applications evolve, data access and processing speed become even more critical. Applications need to read and write data millions of times per second, which requires a reliable and efficient solution. By using caching technology, you can significantly improve application performance while reducing access to the database server.

NCache is an in-memory object caching solution that can scale application performance and improve application responsiveness. It is a cross-platform solution that supports Windows, Linux, and macOS. This article explains how NCache caching technology works and its benefits.

The principle of NCache caching technology

NCache uses an internal object cache to store objects in the application. When an object needs to be accessed, if it already exists in the cache, it is returned directly from the cache; otherwise, the application retrieves the object from the database or other data source and stores it in the cache. This means that every time an object is accessed, NCache checks whether the object exists and loads it from the data source if necessary.

NCache also uses some advanced caching techniques to optimize the management of internal object state. For example, it uses distributed hash tables to ensure balanced data distribution of objects. This ensures that all cache servers can jointly manage cache objects and achieve load balancing across the entire cache cluster.

NCache also supports automatic cache expiration and clearing functions. Through these functions, objects in the cache can automatically expire within a specified time to avoid excessive storage of objects in the cache. At the same time, cache space can be recycled by adding a recycler.

In addition to regular caching, NCache also supports distributed caching. This caching technology enables high scalability and high availability by distributing cached objects across multiple cache servers. When a cache server fails, the distributed cache can automatically copy data from the failed node to other available nodes.

Advantages of NCache caching technology

NCache caching technology brings many advantages. Here are some of the main benefits:

1. Cache: Using NCache caching can significantly reduce the access time of your application. Because the NCache cache is an in-memory cache, it has direct access to objects, thus avoiding disk access. This means objects can be read and written at millisecond speeds.
2. Reduce database load: Using NCache caching can reduce access to the database server. When an application needs to access data, it can read it from the cache instead of reading from the database every time. This reduces the load on the database server and reduces the server's response time.
3. Highly scalable: Because NCache cache can be extended to multiple cache servers, it can achieve high scalability. This means that the application can handle large data requests without impacting the server's performance.
4. Improve data security: NCache uses multi-layer authentication and authorization to ensure that only authorized users can access cached objects. It also provides many security options such as SSL secure connection to ensure that the data in the cache is protected.
5. Improve application performance and availability: By using NCache caching technology, application performance and availability are significantly improved. Because NCache caching employs a variety of availability and performance optimization techniques, it is ideal for applications that require fast response times and high availability.

Summary

NCache caching technology is a high-speed, high-availability object caching solution. It can significantly improve application performance and reduce database server access while achieving high scalability and data security. Using NCache caching technology ensures that your application responds quickly and provides a high-quality user experience.
