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:
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.
The service order request will be processed within 3 working days. The user will be notified of the outcome of the evaluation via email.
In case the service order is accepted:
- The user will be notified by the Marketplace with the instructions to redeem the voucher (in case it was not provided), generate a client and secret keys and access the Elastic Cloud Compute Cluster (EC3) portal.
- To redeem an Exoscale voucher, open the provided voucher link included in the email sent by the Marketplace within a web browser.
- A typical link looks like:https://portal.exoscale.com/register?coupon=XXXXXXX
- Enter the email address and password you wish to use. Accept the terms and hit sign up.
- A validation email is sent. Check out your mailbox and click on the verification link.
- Choose “for team projects” and fill your details. Choose your “Company or team name” and submit the form.
Access to the Exoscale dashboard
Access the Exoscale dashboard and check the tenant settings (click in the User profile on the left)
Check the voucher credit
Access the Exoscale dashboard. The voucher credit is shown in the top-right of the dashboard. In case voucher credit is going to expire, a notification email will be sent by the dashboard.
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.
Acknowledgement and report feedback
The user MUST acknowledge the EOSC-hub and the HNSciCloud projects in the scientific publications/presentations benefiting from the service. The following acknowledgement statement can be used for this purpose:
