It’s Again to the Database Future for Exasol CEO Tewes


When Joerg Tewes final labored within the database enterprise, the world was simply changing into conscious of the probabilities of non-relational knowledge fashions. Quick ahead 20 years, and NoSQL databases are commonplace throughout all industries, and the most important transition dealing with the business is the transfer to the cloud. Because the just lately named CEO of German analytics database maker Exasol, Tewes will thread the needle between clouds and on-prem.

Tewes began his profession in 1990 at a software program developer for the German firm Poet Holdings, the developer of the POET object-oriented database. He oversaw the database’s improvement right through an IPO and left simply earlier than the corporate merged with one other NoSQL database maker, Versant, now a part of Actian.

His IT journey took him to Silicon Valley, the place he made his mark in different fields. Tewes went from video manufacturing (Pinnacle Methods after which Avid Expertise) to shopper electronics (Logitech, the place he led improvement of Webcams and the Concord distant), again to video and augmented actuality (Avegant), after which again to shopper merchandise (main improvement of Fireplace tablets and Kindle e-readers at Amazon).

When he was provided the highest job at Exasol late final yr, he regarded ahead to not solely getting again into databases, however shifting again to his homeland.

“A part of the cope with the corporate was that I used to be relocated again to Germany, which I did,” Tewes tells Datanami in an interview. “I lived within the Bay Space for 15 years. I only recently moved again to Germany about three months in the past, so I nonetheless have that California sunshine in my thoughts.”

That California sunshine is considerably obscured by clouds. Because the pandemic, the migration to the cloud has been in overdrive, as AWS, Google Cloud, and Microsoft Azure racked up large buyer beneficial properties. Databases, as one of many main repositories for enterprise knowledge, have proliferated within the cloud.

Joerg Tewes was named CEO of Exasol in January 2023

The transfer to the cloud is “tectonic shift,” from Tewes’ perspective.

“Once I was within the database world [before], it was principally a on-prem server world. There was no cloud at that cut-off date,” he says. “Each firm has their server someplace of their knowledge middle, and so you’d have a client-server structure, and I feel that’s dramatically modified with the cloud.”

Nevertheless, not each firm desires to run within the cloud, Tewes says. For some, the hesitancy to maneuver to the cloud is because of issues over the unintentional disclosure of delicate knowledge. European corporations, specifically, are extra attuned to legal guidelines like GDPR and are extra delicate about handing over management of non-public knowledge to American cloud giants, he says.

“Given what’s occurred within the political universe over the past 5, six years, the issues have elevated, particularly in Germany,” Tewes says. “Germany has this large dependency on the pure fuel pipeline from Russia. And a few folks in Germany argue, effectively, we’re additionally depending on IT infrastructure generally on main U.S. corporations.”

One other cloud concern pertains to price will increase. Within the on-prem world, spending on infrastructure is finished up-front, and prospects are capped on capability. However within the cloud world, capability is principally limitless, and so is the price.

“Loads of corporations get into that scenario the place they both have main efficiency points, or with among the cloud databases, run into considerably greater prices of their deployment,” Tewes says.

Tewes’ technique with Exasol is to assist prospects speed up present analytic workloads wherever they’re working. Whereas Exasol can function a main analytics database for 100TB to 300TB knowledge warehouses, it has discovered a snug area of interest serving as an accelerator for present knowledge warehouses. By slipping in between the front-end BI software and the backend knowledge warehouse, Exasol can assist to goose present queries and scale back the wait time for customers.

“We principally assist prospects to take away a ‘spinning wheel’ that they may have, as a result of over time, knowledge quantity simply will increase and parallel queries occur,” he says. “It’s in a manner a ‘land and increase’ technique. That’s the place we’re getting the traction and pleasure.”

The excellent news for Exasol prospects is it will probably work with a big number of databases. It doesn’t matter whether or not they’re working an older on-prem warehouse or working one of many newer cloud knowledge warehouses. Exasol’s MPP analytics database can slip in as an accelerator.

“What we’re attempting to keep away from is clearly to go head-to-head with Snowflake and Databricks,” he says. “They’ll stick with what they’re utilizing. Let’s say they’ve a legacy Oracle or Teradata, or possibly two environments. They’ll maintain that, and so they can use us as an acceleration layer in between to principally scale the system.”

The necessity to help on-prem databases is especially essential for patrons, he says.  “There’s nonetheless a variety of corporations that really have on premise databases–for good causes,” he says. “They’ve safety, regulatory causes to maintain the info in their very own knowledge middle. They wish to have management over it.”

Whereas European corporations are probably the most hesitant to maneuver their knowledge into the cloud, Exasol additionally has some U.S. corporations that will reasonably simply maintain their knowledge on-prem, Tewes says. “We do have prospects which have delicate private knowledge that they don’t wish to be within the cloud,” he says.

In the long run evaluation, giving prospects the pliability to run both within the cloud or on prem is essential to Exasol and its prospects. That was the main focus of model 8 of the database, which was just lately launched.

“It provides our prospects the liberty of selection, which I feel is essential,” Tewes says. “To allow them to both have an on premise resolution the place they get that, or they will additionally run our database in their very own cloud accounts, like in their very own AWS, GCP or Azure account. Or now we even have a SaaS providing the place we principally handle the info for buyer.”

Exasol has a comparatively small group within the US, with about 20 folks. However the firm has attracted some massive names, together with T-Cell, Verizon, and Dell as prospects, so it’s confirmed that it’s able to supporting Fortune 500 companies.

Whether or not or not prospects run their knowledge warehouse on-prem, within the cloud, or someplace in between the one fixed can be a rise in knowledge that wants analyzing. By specializing in enabling prospects to maximise analytics efficiency whereas sustaining flexibility, Exasol will possible discover its enterprise rising too, which ought to assist it meet its aim of reaching profitability in 2023.
