As developers, we often need to execute tasks in the background. Fortunately, some tools already exist for this. In the Python ecosystem, for instance, the most well-known library is Celery. 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

Abstract As a researcher I need to conduct experiments to validate my hypotheses. When the field of Computer Science is involved, it is well known that practitioners tend to drive experiments on different environments (at the hardware level: x86/arm/…, CPU frequency, available memory, or at the software level: operating system, versions of libraries). The problem

When discussing the concepts of DevOps and Infrastructure-as-a-Code, the tools developed by HashiCorp quickly come up. With Terraform, HashiCorp offers a simple way to automate infrastructure provisioning in both public clouds and on-premises. Terraform has a long history of deploying and managing OVH’s Public Cloud resources. For example, you can find a complete guide on

The CDS Workflow is a key feature of OVH CI/CD Platform. This structuring choice to add an additional concept above CI/CD pipelines and jobs is definitely an essential feature after more than three years of intense use.
Before going further on the explanation of a CDS workflow, we will make some reminders about the concepts of pipelines and jobs. Those concepts are based on the reference book 8 Principles of Continuous Delivery.

From git commit to production, the delivery process is the set of steps that take place to deliver your service to your customers. Continuous Integration and Continuous Delivery – CI/CD – are practices based on the Agile Values which aim to automate this process as much as possible.
The Continuous Delivery Team @OVH has a mission: to help the OVH developers to industrialize and automate their delivery process. The CD team is here to advocate CI/CD best practices and maintain the ecosystem tools, with a maximum focus on as-a-service solutions.
The central point of this ecosystem is a tool built in-house at OVH, named CDS.
CDS is an OVH opensource software, you will find it on https://github.com/ovh/cds with documentation on https://ovh.github.io/cds.
