What began as a gathering of 100 people now welcomes over 7,000 attendees at a time. More than 200 exhibitors from around 70 different countries and over 250 different experts in the field attract the brightest minds in the hosting and cloud industry every year. Most of these partners include the biggest names in the computing industry—names like Intel, VeriSign, Dell, HPE, Google Cloud, AMD, Toshiba, and many more.

CloudFest takes place every year in spring at Europa-Park in Rust, Germany, which is transformed into a different kind of playground. The event is all about the latest technologies, innovations, and product presentations, but also hosts workshops, meetings, and networking. The enormous growth of technology and the challenges we face these days require a focus on the development of real-world solutions during this event. This involves all aspects of safety, security, protection, service quality, and ownership within the scope of online activities.

Besides bringing in top-flight speakers from within the world of the cloud, we reach into other worlds as well, to bring more dimensions of creativity and entrepreneurship to the table.

CloudFest is known worldwide for bringing an element of fun to its event that is rarely seen at tech conferences. In 2019, WHD launched its own music festival, Loud in the Cloud, for that year’s edition of CloudFest. The in-house band was joined by DMC of legendary hip hop group Run DMC, as well as rocker Sebastian Bach from Skid Row. Loud in the Cloud is set to become its own tradition, and is returning for 2021.

Looking to the future, CloudFest is committed to producing events that bring visionaries and decision-makers together, foster new ideas, and help attendees proactively drive their industries forward. We aren’t content with simply keeping up with changes in the Cloud industry: by pushing the boundaries of what a conference can be, we help our partners and attendees shape the industry themselves. As ever, our events are made with love in Cologne: this slogan is a shout-out to the location of the company’s headquarters, where the planning and organisation of CloudFest is handled by 17 employees.

WorldHostingDays, the company behind CloudFest, is headed by CEO Soeren von Varchmin, who has a knowledge of the global domain, Cloud, and internet infrastructure markets; and maintains thousands of C-level contacts in this area. The main goal of WHD is to create a community that is constantly working on new innovations, new technologies and the emergence of collaborations—taking the original idea and making that gathering of friends a lot bigger.


In the Beginning, There Was Hosting…

The global hosting and cloud services market is gigantic, with over a billion websites worldwide— and everything from mobile apps and social games to email and mission-critical business software running in the cloud. But at the same time, giants like Facebook, Microsoft, Alphabet, and Amazon are fundamentally shaping the social, economic and political landscapes that impact us all. Meanwhile, hackers are stealing data, user information gets weaponized to change the course of democratic elections, and governments are issuing new—and sometimes conflicting—laws and regulations every day. Meanwhile, people are storing more personal information online than ever before. Then a global pandemic happened… so, yes, it’s complicated out there.
