Plan your route


Travel by Plane

Berlin airports: Tegel Airport in the northwest of Berlin and Schönefeld Airport on the southern outskirts. S-Bahn trains, as well as regional trains, leave the Schönefeld Airport directly for the center of Berlin. From Tegel Airport the city center is easy to reach with the TXL Express bus.

Travel by Car

From any direction, all highways and national roads lead to the capital city Berlin. They all cross the highway which encircles Berlin, known as the “Berliner Ring.” From there urban highways and exits – marked with the word “Stadtmitte” or “Zentrum” – guide drivers towards the center of Berlin. Car and bus parking available in front of the building.

Travel by Train

Travelers arriving in Berlin by train arrive at one of Berlin’s main train stations. Almost all trains stop at the Central Sation (Hauptbahnhof) as well. All railway stations have direct links to public transportation (taxi and subways).

Friday Product Session #1

“Increase Revenue with Trusted Internet Services: a Technical Deep Dive”

Relying on the credibility and technical capability of one’s Cloud Provider for the Internet is massively important: as an individual using the Internet; as a commercial business; and even as a Hoster needing to extend an offering via partners. Trust is a critical factor we count on for the innovation and commerce the Internet delivers. Come to this session to hear first-hand which technology and open source integrations are delivering the next level of profitable Internet services on the Internet. After all, much of the success Google, Facebook and Apple have experienced has been developed on open source code and philosophy. Come to this session to learn from the Dovecot experts who have deployed the leading IMAP server worldwide on more than 3 million Linux servers and why this approach scales your Internet business beyond expectation.

Friday Product Session #2

“The Best Customer Experience on the Internet requires DNS: the Technology of Speed and Performance explained"

Running an Internet service and/or business has become extremely complex with all the dependencies that are required to remain agile and customer-centric via IT services. And most service providers and large telcos are completely unaware of how detrimental a slow Internet or outage can become. Until it happens: your Internet goes down. Come to this session to understand from the global leaders of DNS technology how critical, exceptional 24/7 support and rock-solid DNS infrastructure is in transforming the business of your IT.
Bert H., Founder & Session Facilitator | Peter van Dijk, Technical Expert | Pieter Lexis, Technical Expert


Friday Product Session #3

“Technically Speaking: What OX App Suite can deliver with Privacy, Guest Mode and Mobile App Functionality"

As a hoster, service provider or telco, staying engaged with your customers who consume a variety of online services is challenging at best. Both price and user experience weighs heavy on the decision to frequency and usage of an app or online service. The Open-Xchange portfolio has greatly expanded to include more functionality that Service and Cloud Providers require to remain competitive. With the introduction of OX App Suite 7.8, the amount of valued and trusted services that providers can now offer their customers has as well as new business and revenue model implications. Come to this technical product session for a deeper technical understanding on how OX App Suite — when integrated with core security and sharing differentiators like OX Guard with PGP, OX Drive and OX Documents — is engaging whole new customer-segments for Service Providers looking to scale their business and revenue growth.
