A Brief History of "Sky"

Before going further, I think it would be interesting to give you a brief history of our old BizTalk 2000/2002. In order to keep this blog anonymous, I have changed the name of the company I am working for to "My Company", the name of the middleware has been changed to "Sky", and the different code-names for projects have been changed as well ;-)

At the end of the year 2000, My Company started a pilot project with the code-name "Atlanta". The goal of this project was to establish a Vendor Managed Inventory (VMI) process between My Company and its key customers. The principle of VMI is that the customer does not have to order products any more, but rather sends on a daily basis their level of stock and a forecast of their consumption (of products). Based upon that information, the supplier ensures that the customer’s stock level is always maintained sufficiently to cover their consumption. On the customer side, there is no longer a need for purchasing activities, and on the supplier side, production and delivery can be optimised. The "Atlanta" pilot project successfully went live in April 2001, and became the major supply chain tool, which today continues to be successfully implemented with several key customers.

From the beginning of the "Atlanta" pilot, we had identified that integration will be key in the success of the project. We had to integrate the VMI tool with (1) the ERP system of the customer, keeping in mind that our new customers would have different ERP systems; (2) the ERP system of the My Company pilot plant, keeping in mind that our new customers may deal with other My Company plants using different ERP systems. Consequently, we decided to include within the scope of the pilot project, the implementation of a central message broker. Microsoft BizTalk 2000 was selected as the technical platform.

After the successful go-live of the "Atlanta" project, it was recognised that My Company could take advantage of the newly implemented central message broker. In this context, the "Hermes" project was launched with the goal of establishing a central message broker, which would enable a standard (common) and reliable approach for application integration within My Company (across all regions and systems) as well as with our trading partners. After some successful pilot projects, the central message broker was accepted and it has been known as Sky, the My Company Integration Service, since April 2002.

In April 2002, a Sky Coordination Group was created, which has contributed to the exponential use of Sky for all the internal and external integration needs of My Company. Today, there is a network of 16 dedicated specialists working together, committed to maintaining a prompt and cost-effective response for all integration needs.

In addition to the growth in terms of volume, Sky started supporting more and more integrations between critical business applications and so the "Athena" project was launched in January 2004 with the goal to ensure the high availability of Sky. Since November 2004, Sky has been running on a highly available clustered infrastructure.

Today (November 2006), Sky interconnects around 280 different systems, using more than 320 different message formats. There are more than 2,000,000 messages per month exchanged across more than 2,200 routes (a route is defined by the: source, incoming format, mapping, outgoing format and destination).
