During my work at Adroitlogic, in one of my tasks I had to start & configure a set of EC2 machines which included our B2B AS2 integration solution AS2Station. This was a recurring task and yes you guessed right it was boring. The configuration steps in summary were follows.
- Extracting the private IP of eth0 interface
- Adding few iptable rules with the extracted private IP
- Mounting a ramdisk (which is used by the UltraESB filecache)
- Starting Apache Zookeeper service (which is the leadership election and coordination service used by UltraESB)
- Starting UltraESB service
- Starting AppServer service (which is AS2Station front-end)
My good friend Janaka, suggested me that I should try to use an startup script to get this done. Turns out it was pretty easy. Let me share the steps with you all as it might be useful to some of you as well.

The Applicability Statement 2 or AS2 specification defines a mechanism for the secure and reliable transfer of structured business data over the Internet.
AS2 Message Payloads
The AS2 protocol itself does not dictate any limits on the payload of an AS2 message. However. typical AS2 payloads are structured business documents such as Invoices, Purchase Orders etc. and thus AS2 systems facilitate the Electronic Data Interchange or EDI. Some of the major sets of EDI standards are:
- The UN-recommended UN/EDIFACT is the only international standard and is predominant outside of North America.
- The US standard ANSI ASC X12 (X12) is predominant in North America.
- The TRADACOMS standard developed by the ANA (Article Numbering Association now known as GS1) is predominant in the UK retail industry.
- The ODETTE standard used within the European automotive industry
AS2 messages can carry non-EDI payloads such as XML, CSV, Fixed Width, Text, or payloads of other standards or proprietary formats, including any binary files.

In February, AdroitLogic released UltraESB-X, a completely redesigned ESB which is developed by the very same team who developed the UltraESB six years ago. UltraESB-X is developed inline with UltraStudio, a user friendly graphical tool to easily create, manage and test integration flows. In the user’s point of view, UltraESB-X mainly has two new concepts namely connectors and processing elements.
What is a Processing Element?
A processing element is an element which performs a specific processing requirement or business logic on the message. It can be one among a wide range of operations such as filtering using conditional branching, transformation, flow control, scope handling such as a transactional scope and many more. Usually processing elements in the UltraStudio editor are represented by an icon with a bluish background except for a few exceptions. One of those exceptions is the scope processing element family which uses a purple background and another set of special flow control processing elements which uses a reddish background.
The structure of a processing element is as shown in the above image. There is an In Port (grey colour) which takes a message in, then depending on the type of processing there can be zero or more Out Ports (light yellow) which gives a processed message out and finally there is the On Exception Port (red) which is used to forward the message in case an exception occurs during the processing logic of the element. UltraESB-X ships with dozens of built-in processing elements which covers a wide range of integration processing requirements and more processing elements are continuously added with each release cycle. Current list of processing elements can be browsed through the developer portal of AdroitLogic here. Apart from the inbuilt processing elements, UltraStudio allows user to write their own custom processing elements as explained in the documentation.

We at AdroitLogic recently released UltraESB-X developed on top of the flexible, extensible and lightweight Project-X platform. UltraESB-X comes with a GUI developer tool, UltraStudio, to develop, test and package your integration flows easily. Along with this we released Integration Platform Server (IPS), our PaaS solution to manage the deployment, maintenance and scaling of UltraESB-X clusters. When it comes to these enterprise integration products, one thing you can’t keep away is the requirement for statistics and monitoring. AdroitLogic Integration Platform comes with inbuilt monitoring and statistics support and we are in the process of developing our enterprise level monitoring solution IMonitor for UltraESB-X. Since UltraESB-X publishes metrics to the famous, distributed RESTful search and analytics engine Elasticsearch, we can use the open source visualization tool Kibana for monitoring as well. So today we will go through the steps to setup UltraESB-X monitoring with Kibana.
