"VEXXHOST did a great job performing an in-place upgrade of our OpenStack cluster to their Atmosphere platform. The team worked efficiently and performed the upgrade with limited downtime. They went above and beyond to help us debug, post-upgrade networking bugs. Lightcast is very happy with the end result and we look forward to operating a much more stable and maintainable OpenStack cluster!"
Curtis Spencer
Senior Infrastructure Engineer
Lightcast
"We recently had our Cloud converted over to Atmosphere and it has been nothing but a positive experience. All the features we wanted are implemented by default and rolling out upgrades and fixes is a breeze. I feel like the support that we have has gotten even better since converting to Atmosphere because the VEXXHOST team is continuously developing and improving it and we are able to get fixes and features into our deployment very quickly."
Salvatore Guercio
Systems Administrator
Center for Computational Research
"Initially, we ran half a trillion links across 70 nodes, taking 80 to 90 days. However, since transitioning to the Atmosphere platform, the same task now takes just 3 days. This significant improvement in efficiency has saved us time, allowing focus on other critical work aspects. The platform's reliability and performance have truly impressed us."
