Requirements

Resource Centres are free to use any Cloud Management Platform as long as they are able to integrate with the EGI Federation components. At the moment this compliance is supported for OpenStack open-source cloud platform.

The general minimum requirements are described below.

• Relevant parts of PROC09 Resource Centre Registration and Certification have been successfully completed

• Hardware requirements greatly depend on your cloud infrastructure, EGI components in general do lightweight operations by interacting with your services APIs.

  • Image sync requires enough space to store the community images into your local catalogue. The number and size of images which will be downloaded depends on the communities you plan to support. For the operations VO ops, a < 4GB image is used.

• Servers need X.509 host certificates in order to authenticate to each other or to act as public endpoints in the EGI Federated Cloud context. For accounting purposes one IGTF-accredited X.509 certificate is needed per site, but the other public endpoints can use ordinary certificates (issued by Let’s Encrypt for example).

  • For the IGTF-accredited certificates, a list of national / regional Certificate Authorities is available at EUGridPMA Membership; it is expected that the Resource Centre will obtain the IGTF certificate from a close Certificate Authority

• For operational purposes, the ops VO needs to be supported by the Resource Centre as per Resource Centre OLA. Also at least one community VO that supports EGI users is expected to be supported by the Resource Centre (i.e. vo.access.egi.eu for piloting and prototyping FedCloud usage).

• The public endpoints need to have proper firewall configuration (to allow inbound external access)

• A flavor (a preset configuration that defines the compute, memory, and storage capacity - min 8 GB - of an instance) needs to be made available by the site for monitoring purposes.
