European annual conference: The Force is with Tableau Software!

By: Guy Hervier

“The best of (two) worlds”—that is the message that Tableau Software wanted to convey at its 8th Annual European Conference in Berlin.

It was a reassuring speech that Adam Selipsky, CEO of Tableau delivered at the European Conference in Berlin just days after the acquisition by Salesforce for more than $15 billion, the largest acquisition by Marc Benioff, only 20 years after the creation of the company.

“Within Salesforce, Tableau will continue to exist as a brand and keep some independence,” said Tableau’s CEO to more than 2,000 users. This is a necessity since Tableau must be able to continue to be used with dozens of data sources from competing editors (Tableau provides around 80 connectors). A positioning that, in the field of infrastructures, could be compared to that of VMware within Dell Technologies or Red Hat within IBM. “Salesforce will create new opportunities even if it is too early to give more details,” he continued.

The message concerning the acquisition was simple: understanding data is Tableau’s mission, knowing the customers is Salesforce’s mission. The union of the two suppliers creates an obvious synergy “while presenting no overlapping” says Edouard Beaucourt, Head of Southern Europe and Country Manager at Tableau.

The first complementarities that Tableau will be able to benefit from, are the use of artificial intelligence technologies with Einstein or a wider integration via APIs following the acquisition of Mulesoft by Salesforce last year. Like a lot of software today, Tableau can be used through three forms: on-premise, via a public cloud (the software is available on AWS, Azure and Google Platform) and in a form of managed services by Tableau. The additional cost between public cloud and managed services by Tableau (software is also installed on AWS), which allows companies to discharge their management of the application, is about 20%. The acquisition by Salesforce, which was one of the pioneers of software in SaaS mode, allows to envisage the eventuality of using the latest cloud infrastructure.

The acquisition opens a new chapter in the life of Seattle’s other software company, enabling it to accelerate its development. Moreover, “the integration of the two companies will have to be carried out with a lot of caution,” considers Adam Selipsky, “because the projects realized with Tableau are now strategic for a number of companies.”

Tableau presented Blueprint which offers Tableau users tips and practices to help them develop their analytical skills and to build a true data community. Blueprint brings together information and services related to best practices to implement a project, the editor highlighted three major factors: agility, expertise and community.

In its presentation of its digital transformation project, Lloyds Banking Group spotlighted the third factor concerning the success of switching from 0 to 6000 users in just three years and making Tableau a major resource. “If Lloyds, with its bureaucracy burdens and regulatory constraints, could do it, all companies can,” said representatives of Group Analytics, a center of excellence aimed at transforming the bank into a “data driven enterprise”, a development, which is completed when the decision-making is based on facts and not on intuition. “We use Tableau to do almost everything,” explained Fred Thomas, “from customer segmentation, marketing performance to product activities or customer behavior.”

Since the last edition of the European conference, Tableau has introduced four new versions (referenced 2018.2, 2018.3, 2019.1 and 2019.2). The next one, planned later this year, will allow a move from the natural language data query phase with Ask Data to the data explanation phase with Explain Data, a range of functionalities based upon AI technology in order to detect and automatically provide explanations of the value of a specific data point, and in order to help users understand the “why” of their data more quickly.

Towards the concept of platform

“We have evolved from a best of breed configuration to a real platform,” explained Edouard Beaucourt, on the sidelines of the conference, notably with the integration of a high-performance column-based database engine through the acquisition of the German editor Hyper in 2016. This was a way to solve a performance problem and support projects of much greater magnitude.

In France, Tableau is historically present within startups such as Kapten (formerly Chauffeur Privé) or Blablacar, for whom the understanding of data is strategic, as well as institutional or traditional players such as La Poste or BNP Paribas. Other French customers include Schneider Electric, Auchan and EDF, each with several thousand users. “For the future, we will focus on middle-market companies,” specified Edouard Beaucourt.

Among the other announcements of this conference, the McKinley project aims to boost Tableau Server to improve scalability, performance and security, being available by end of the year.

The democratization of data is a topic that is at the heart of the creation of Tableau Software. A topic that is not new and yet the path to what is called “data literacy” is still long. This is the statement of Lloyds but it is also the challenge that attempts to meet the Deutsche Bahn, the German equivalent of the SNCF. The goal of this specialist in transport (train of course but also any other type of mobility such as bike sharing systems or cars...) which employs more than 330,000 people is to make each employee a data player. DB Systel, a kind of external DSI that employs 4,000 people and provides all infrastructure and application services in the form of paid services, has developed a dashboard that ultimately could be used by all employees of the company and why not by customers. For example, a project developed with the database based on the Neo4j graphs allows visualization of the whole network (about 33,000 km) and the different possible itineraries between two cities according to the distance, the cost and the time of transport.
