DIRAC Pilot running on Microsoft Azure

Introduction

The objetive of these tests is to probe the feasibility of the usage of Microsoft Azure as a DIRAC cloud resource.

In particular, our main interest is the deployment of virtual machines, ready to accept jobs of the Belle VO, inside the Azure infrastructure.

Microsoft Azure works with two provisioning models: Resource Manager (ARM) and Service Manager (ASM). The ARM is the most recent model implemented by Azure and is the recommended election for new develops. The advantage is the deployment of resources using JSON templates, who simplifies a lot the tasks.

For our convenience, we are using the ARM model in the tests.

The VM image used in the tests is CernVM, who includes a setup ready to work with Azure and a CVMFS client with access to the Belle II repositories.

The communication with the Azure infrastructure can be handled by the web portal, the client for PowerShell, the client for Bash and the SDK for several languajes (Python, Javascript, Ruby, etc).
