NCache is an open-source, in-memory distributed cache that accelerates the performance of .NET and Java applications by caching frequently accessed data, ensuring fast transactional speeds and linear scalability. Its distributed architecture allows seamless scaling by adding more nodes, automatically balancing the load, and providing consistent performance as traffic and data volume increases. Unlike other caching solutions built on C++ or Linux, NCache is specifically designed for .NET environments, offering seamless integration. Being a market leader for almost 2 decades, NCache enables developers to build high-performing, reliable systems that easily handle mission-critical workloads. This blog will discuss how NCache can transform your applications into high-performing, scalable systems.
Which .NET Applications Need NCache?
NCache empowers applications to handle high traffic, ensure faster data access, and scale effortlessly as demands grow. You can integrate NCache in the following high-transaction applications.
- Web Applications (.NET/.NET Core)
- Web Services Applications (.NET/.NET Core)
- Micro-services Applications (.NET/.NET Core)
- Server Applications (.NET/.NET Core)
NCache As a Solution
Modern applications must deliver high performance and achieve scalability to handle increasing workloads. Without a robust caching solution, your application may experience delays and downtime since all application requests go to the backend database, which is not designed to scale seamlessly. This creates performance bottlenecks, chokes the database under high transaction loads, and risks a single point of failure.
NCache, as an in-memory cache, reduces database load by caching frequently accessed data. Its distributed architecture pools memory and CPU across multiple servers, ensuring seamless scalability and high availability under heavy transaction loads as discussed below.
- Handling Extreme Transaction Loads: During peak traffic, applications risk degraded performance and downtime as all data requests hit the database. NCache addresses this by reducing database queries by 80–90%, preventing bottlenecks, and ensuring uninterrupted service during high traffic or database issues.
- Supporting Customer-Facing Websites: For businesses relying on online platforms, performance and availability are non-negotiable. Such as e-commerce stores need to handle high traffic during sales; airlines need to process ticket reservations efficiently; and gaming platforms need to deliver real-time updates without delay. To overcome these challenges, such businesses can use a reliable caching solution like NCache that provides them with high availability, data reliability along with high performance.
- Background Processing Businesses: Industries like banking, logistics, and utilities depend on real-time data for tasks such as fraud detection and device monitoring. NCache’s robust Pub/Sub and event management capabilities efficiently synchronize workflows, ensuring reliability for critical operations.

Such businesses can’t afford to have their applications slow down during peak times. Without a caching solution like NCache, the impact can be severe—lost revenue, frustrated customers, and reputational damage. NCache ensures fast, scalable performance, preventing bottlenecks and maintaining smooth operations even under heavy loads.

Key Features of NCache
Let’s explore some of the key features that NCache offers.
Keep Cache Fresh
NCache provides several methods to keep your cache data fresh without any manual intervention. For instance, Absolute and Sliding Expirations automatically remove expired data from the cache and keep it up-to-date. Another way to keep your cache updated is through Dependencies which remove outdated data whenever changes occur in the database, keeping your cache updated and aligned with the latest information.
SQL Searching
For large datasets, NCache offers powerful search capabilities, allowing you to quickly search data based on object attributes, Groups, Tags, or Named Tags. You can perform searches using SQL or LINQ queries to access data quickly. NCache further optimizes search performance by automatically creating indexes, significantly reducing search times even in large-scale applications.
Server-side Code
NCache is the only .NET solution offering server-side code capabilities. With Read-through, your cache can automatically fetch data from the database ensuring that your cache is always up-to-date. Write-through updates the database directly from the cache, while Write-behind updates the database asynchronously, ensuring your application remains responsive without waiting for database responses. Additionally, the Cache Loader pre-loads the cache when the application starts,
Client Cache (InProc Speed)
NCache offers a unique Client Cache feature, also known as Near Cache, which delivers in-process (InProc) performance. It works as temporary storage that resides near the application process for fast data retrieval. While staying fully synchronized with the main caching tier, it ensures real-time updates from other applications or users. As a result, your application becomes more efficient and responsive, without needing constant access to the central cache or database.

WAN Replication of Cache
NCache enables seamless cache replication across multiple data centers, Azure regions, or AWS availability zones without affecting application performance through its WAN Replication feature. It supports both Active-Passive and Active-Active configurations, ensuring high availability, fault tolerance, and load balancing. As such, this feature synchronizes your cache across distributed environments, ensuring data consistency and peak performance across all locations.
