ASP.NET Core is starting to become popular for developing web applications because of its cleaner and lighter architecture and cross platform support. And, many of these ASP.NET Core applications are high traffic and run in a load-balanced multi-server deployment. In fact, it’s very common to see 10-20 server web farms and some are much larger…

Publisher Subscriber design patterns are an invaluable tool for building enterprise grade .NET/C# applications. Among them you will be very familiar with the Publish-Subscribe pattern also known as Pub/Sub. Just to refresh your memory, Pub/Sub is basically a messaging pattern where the senders of messages (publisher) do not have any knowledge about the intended recipients…

Businesses today are developing high traffic ASP.NET web applications that serve tens of thousands of concurrent users. To handle this type of load, multiple application servers are deployed in a load balanced environment. In such a highly concurrent environment, multiple users often try to access and modify the same data and trigger a race condition….

ASP.NET web applications, .NET web services applications, and other .NET server applications need to handle extreme transaction loads without slowing down. And, although their application tier scales linearly, the data storage and database tier does not scale and therefore becomes a bottleneck. As a result, the entire application cannot scale. Originally, simple in-memory distributed key-value…

Update: Microsoft has extended the AppFabric support to April 11th 2017. The extension is only applicable for AppFabric 1.1 and not for 1.0. For more information check out their blog post. April 2nd 2016 (April 11th 2017) is proving to be an important date for Alachisoft’s product NCache. This is the date when Microsoft ends AppFabric support – essentially withdrawing…

Some of the very basic needs for .NET applications to stay competitive in today’s market are to be extremely responsive and scalable. The bottleneck in the way of achieving these benchmarks is your relational database. This is a two fold bottleneck, first the reads from disk are very inefficient and time consuming. Secondly, you cannot…

The database tier based on traditional RDBMS has proven to be the biggest bottleneck in the way of achieving competitive response times for applications. This has forced the application vendors to look for alternatives that can provide improved performance. One such alternative is storing data in a distributed cache. From the available cache technologies you…

Redis is an in-memory key value store developed in C/C++ with clients for various programming languages like .NET, Java and C. Redis has features to tackle critical issues but falls short in some fundamental aspects. NCache – a .NET distributed caching solution on the other hand when compared with Redis answers all these concerns effectively…

ASP.NET View State is a client side state management mechanism, which is used to save page and control values. ASP.NET View State is a hidden field on the page as an encoded Base64 string. It is sent to client as part of every response and is returned to the server by the client as part…
