WSO2 Application Server mainly supports hosting Web Services and Web Applications. One of the major features included in the upcoming release (version 4.5.0) of WSO2 AS is the integration of Apache CXF. So from AS 4.5.0 on-wards, CXF users also will be able to host their applications inside WSO2 AS with great ease. Once you deploy your CXF application inside WSO2 AS, it automatically inherits lots of benefits from the underlying WSO2 Carbon platform.

Unlike static server capacity measurements (e.g. CPU processing speed, memory size), performance is a dynamic measurement. Latency and throughput are strongly influenced by concurrency and work unit size. Larger work unit size usually negatively influence latency and throughput. Concurrency is the number of aggregate work units (e.g. message, business process, transformation, or rule) processed in parallel (e.g. per second). Higher concurrency values have a tendency to increase latency (wait time) and decrease throughput (units processed). Read Srinath's full blog post.

This article introduces performance and discusses why architects should consider performance implications when creating solution architecture. Then the article dives into Enterprise Service Bus (ESB) performance, and details recent WSO2 ESB improvements and performance impact.

In this article we focus on the performance benchmark aspects of the WSO2 ESB under two different approaches: Message Relay (MR) and Pass-Through (PT). We discuss how efficiently the ESB can handle messages of different sizes under different concurrency levels. We provide a set of detailed statistics to allow comparison of the different approaches.

Representational State Transfer (REST) provides a lightweight approach for building distributed systems. Instead of relying on overcomplicated protocol stacks and heavyweight middleware, REST facilitates communication between systems by leveraging open message formats and basic protocols that power the Web. As a result we see more and more developers adopting the REST paradigm for implementing enterprise applications.

Ability to store a message in a temporary storage is a fundamental requirement in many enterprise integration scenarios. There are many occasions where a systems integrator would have to design a message flow which simply dumps all the messages into some kind of a storage facility for later retrieval. Here are several scenarios that I’ve encountered while working on real-life integration projects which required me to consider using an intermediate message store:..

As one of the largest clubs in the American Automobile Association, AAA Mid-Atlantic offers a broad array of diversified services to over 3 million members. Throughout the years, AAA Mid-Atlantic has been instrumental in safeguarding motorists interests, ensuring member protection, providing roadside assistance, education, advocacy, and a plethora of other services.

As the need arose to further improve the user experience of automobile shopping, AAA Mid-Atlantic recently introduced the new AAA Auto Buying Tools mobile app. As the app design emerged, AAA Mid-Atlantic found a few obstacles in their way -

When you write a complex mashup with WSO2 Mashup Server which aggregate several external web services, you will definitely need to communicate with secured web services. It is very easy with WSO2 Mashup Server as it does this with service composition. In this article, we will discuss how WSO2 Mashup Server allows you to invoke services secured with advanced security scenarios.
