Using the UltraESB to proxy and load balance requests to Tomcat

Traditionally the Apache web server has been used to proxy requests to Tomcat servers using mod_jk or mod_proxy etc. This usually entails configuring multiple configuration files at different locations after making the necessary modules available to Apache. This articles describes how the UltraESB can be used to load balance and fail-over requests to Tomcat servers, and compares with a similar configuration with Apache2 using mod_jk.

ESB Performance Testing - Round 4

This article is based on the 4th round of ESB Performance testing conducted by the author since June 2007. This performance framework has now become the de-facto ESB Performance test suite, with vendors such as WSO2, BEA and Mule using it to publish benchmark results. This round moves the test execution to the Amazon EC2 environment, so that end users can themselves run the tests and verify the results - as well as use the framework to compare any ESB of their choice against the options compared in this report.

Using JTA Transactions with a SOAP, REST or any other Proxy Service

This article describes the simple - yet powerful support for JTA transactions, within the UltraESB. The UltraESB transports are capable of reading a message within a resource local (e.g. JMS local) or JTA transaction - to ensure that a rollback on the message during processing will put the message back into the original location for re-processing. Additionally the UltraESB can perform transactional mediation for messages received over any transport - such as HTTP/S, and this article gives an example.

Configuring the HTTP/S Transport

This article describes the configuration options for the HTTP/S transport listeners and senders

Tuning the UltraESB for performance

This article describes the basic steps on configuring the Operating System to support high performance execution of the UltraESB.

Securing the UltraESB configuration

This chapter discusses some of the best practices for a production deployment of the UltraESB.

Getting started with Endpoints or Destinations

An Endpoint defines an external service endpoint to which a message could be sent by a supported transport. Endpoints maybe defined in-line within a proxy service definition, or defined externally with a name, and referenced by one or more proxy services.

Getting started with Sequences and Mediation

A Sequence definition holds mediation logic to be performed on a message. A Sequence may be defined in-line within a proxy service definition as a sequence local to a service, or defined as a re-usable sequence specified with a name.

UltraESB Users Guide - Getting Started with the UltraESB

This guide introduces the user to the UltraESB installation folder structure, pre-requisites and starting up of the UltraESB using the default scripts

UltraESB Users Guide - The HelloESB Sample

This article describes the default configuration shipped with the AdroitLogic UltraESB, and shows how the sample could be tested and extended/modified using the IDE integration support of the UltraESB. This article also shows how a JUnit test case could be written for scenarios implemented with the UltraESB

UltraESB Users Guide - Configuring and Using the IDE

This guide introduces the user to the UltraESB configuration, testing and debugging with a supported IDE. This tutorial uses the IntelliJ IDEA Community Edition, which is an excellent IDE now available free of charge - which offers intelligent editing of the configuration as well as editing of Java code fragments embedded within the XML configuration elements

Getting started with the AdroitLogic ToolBox for the UltraESB

The AdroitLogic ToolBox is a service and ESB test toolkit bundled with the UltraESB. It allows one to start a sample server instance hosting RESTful web services, JAX-WS SOAP services, and raw HTTP echo servlets, Text and HTML servlets, and then issue sample requests to these services through the HTTP/S client module. The HTTP/S client supports REST, POX, Text and binary payloads (such as Hessian) and supports the POST, GET, PUT, DELETE, HEAD, OPTIONS and TRACE methods in addition to many other features.The ToolBox ships with a built-in TCP dump module, able to report wire traffic as text or Hex formatted binary and additionally allows the message to be saved to a file for replay with a load test etc. Other modules of the ToolBox includes a raw socket level client usually used to test the ability of a service or an ESB to face invalid, malformed or malicious requests, and a high performance HTTP/S load test module. Finally, the ToolBox contains a module that allows a user to easily startup a sample UltraESB configuration with optional editing.
