If you have already used it, you know how great it is! But you will also have probably discovered how complicated it can be to

At OVHCloud, we are open sourcing our “Agility Telemetry” project. Jerem, as our data collector, is the main component of this project. Jerem scrapes our JIRA at regular intervals, and extracts specific metrics for each project. It then forwards them to our long-time storage application, the OVHCloud Metrics Data Platform.

“You don’t have a chance.” “You’re already dead.” “You’ll get eaten alive.” For the last 21 years, I’ve heard people say these things several times a week. They’re often said by people who don’t really understand what OVHcloud does. Never by people in the field. I don’t blame them. They’re clearly thinking “It can’t be

In our previous articles, we explained why we had to move 800,000 databases from one datacentre to another, 300 kilometres away. So here we are… We did it!Now we will focus on a very important goal of any migration. From your point of view, as a customer, you must see… Nothing! I understand this completely,
