Are you a heavy user of open source cloud solutions? Welcome to the club!

CONFERENCE PRESENTED IN 🇫🇷 – Launched this year by Worteks, with the support of the OpenInfra Foundation, the first edition of the Open Source Cloud Heavy Users Club was held in Paris and brought together for the first time the major French players who deploy and operate OpenStack, Kubernetes, and other large-scale open source virtualization solutions.

This group provides a privileged space for technical decision-makers and architects from large groups to exchange and share ideas, offering unique opportunities for feedback, training, and networking.

Within the club, members can:
– Exchange concrete ideas on the production deployment of complex architectures.
– Discuss best practices for integration between Kubernetes, OpenStack, and other open source virtualization solutions.
– Explore possible optimizations, recent innovations, and strategic directions outlined in product roadmaps in order to anticipate necessary changes to existing cloud infrastructures.
– Access the technical expertise of the open source ecosystem.

Come discover the strength of this community and benefit from the initial feedback gathered within the club.
