Marc Adler and Marco Seiriö seem to think so.

Such a deal would seem a little strange coming less than a year after Sybase licensed the underlying complex event processing (CEP) engine for Sybase CEP from Coral8, immediately prior to Coral8′s acquisition by Aleri.

The terms of that licensing agreement provide a clue as to why Sybase would consider opening up its wallet again to snap up Aleri, however.

As Aleri insisted last March, “The licensing arrangement allows Sybase to embed CEP capabilities within and ONLY WITHIN Sybase products such as RAP”.

Sybase later confirmed (clients only) to us that this was indeed the arrangement and maintained that its strategy for CEP was to embed it within larger platform products.

As well as RAP – The Trading Edition, the company’s risk-analytics platform, Sybase also had plans to target opportunities in the telecommunications, healthcare and government sectors.

One justification for the acquisition of Aleri would be that it would allow Sybase to target those markets and other opportunities with a standalone CEP offering based on Aleri’s next-generation engine codenamed Ohio which is slated for roll-out in 2010 and is designed to include the best features from Aleri Streaming Platform and the Coral8 Engine and be backwards-compatible with both.

Then of course there are the Aleri/Coral assets beyond the core CEP engine, including the Aleri Studio visual modeling application, as well as dashboard and OLAP server capabilities, and packaged applications for risk and liquidity analysis and management.

As for why Aleri would sell out to Sybase – we certainly noted some trepidation from the company when we caught up (clients only) in September last year. While the company was buoyant about its plans for Ohio it was reticent to discuss details of customer wins/successes.

The only thing the company would say was that it had more than 80 customers, the number of combined customers when the merger closed.

At that point it was somewhat more confident, claiming (clients only) to be the largest pure-play CEP vendor in terms of headcount and customer base and revenue (although with none of the CEP vendors disclosing revenue figures, that last claim was always highly debatable).

Covering the the complex event specialists just got 25% easier. We noted in September last year that the complex event processing (CEP) specialists StreamBase Systems, Aleri and Coral8 were attractive acquisition targets and that it would only be a matter of time before we saw consolidation in the event processing sector. Consolidation among those vendors wasn’t exactly what we had in mind, but that is what has come to pass as Aleri has announced the acquisition of Coral8 for an undisclosed fee.

The combined entity, which continues to use the Aleri name, is now claiming to be the largest CEP specialist on the market, although that is debatable and we expect it to be strongly debated by StreamBase and Progress Software’s Apama division.

Here are the numbers to be debated: All of Coral8′s 45 employees are joining Aleri, which will have a combined headcount of 95 and will boast 80 paying customers, less than five of which are existing customers of both companies.

We will have a full assessment of the deal and its implications out later today, but our first impressions are as follows:

While the acquisition of Coral8 by Aleri may appear at first glance like a combination of near-equals the resulting business stands to benefit from complementary product and sales strategies that should bring about cost savings via reduced duplication of effort and enable further expansion outside financial services.

CEP is becoming a core enabling technology for data processing and analysis and the new Aleri is well positioned to build on its established position in capital markets and exploit partnerships with business intelligence and data warehousing vendors for wider adoption
