Exoscale vouchers on Applications on Demand

In this section we describe how users can easily discover the EGI Applications on Demand (AoD) service published in the EOSC portal Marketplace and submit a service-order request to deploy an elastic virtual cluster on the HNSciCloud pilot services. The virtual cluster will be deployed and configured with the requested software packages using the Elastic Cloud Compute Cluster (EC3) portal.

Submit a service-order request through the EOSC Portal Marketplace

The EOSC Portal Marketplace is a single entry point where users can navigate the EOSC service catalogue, discover a service of interest, get information about it, and place an order in a few clicks by specifying the service requested along with the quantity, quality and duration.

All the available services of the EOSC Marketplace are grouped in 8 main categories and no authentication is required to browse and discover the list of services published in the marketplace.

Exoscale vouchers can be used when selecting he Elastic Cloud Compute Cluster (EC3) platform from the list of available services by submitting a service-order request.

Placing orders in the EOSC Marketplace requires the user to authenticate. There are two login options: use your personal academic credentials or use EGI Check-in service. The first time you login into the marketplace requires some extra information to be provided to configure the marketplace account.

Two different service options are available for EC3:

The Elastic Cloud Compute Cluster (EC3) service options.

To deploy the virtual cluster on the HNSciCloud pilot services, select the voucher option and click on Next and provide additional information for profiling the order (e.g. the motivation for requesting the service).

Users with an existing Exoscale voucher to redeem can provide the voucherID during the submission request. Otherwise, a valid voucherID will be provided once the order if processed and accepted.

Once the service order is submitted, the marketplace will send a notification via email. Users can at any time the status of their orders through the user dashboard. This dashboard shows the history of service order(s) submitted.

Deploy a virtual cluster on the Exoscale commercial resources

Through a “job wizard” interface (see Figures below) the user can login to the Elastic Cloud Compute Cluster (EC3) portal and configure the virtual cluster with the related tools and applications to be deployed on top of Infrastructure as a Service (IaaS). The cluster is composed by a front node, where a batch job scheduler is running, and a number of compute nodes. These compute nodes will be dynamically deployed and provisioned to fit increasing load, and un-deployed when they are in idle status. The installation and configuration of the cluster is performed by means of the execution of Ansible receipts.
