EGI Federated Cloud Technology For Users For Resource Providers Roadmap and Innovation Task Force Operation


Technical support is available via the EGI.eu Support Team

Users of the EGI Federated Cloud are scientists working in many fields, who can benefit of a flexible environment for running their workloads. Also, the EGI cloud is suitable to projects aiming to provide services and platforms to the scientific community.


The EGI Federated Cloud is a seamless grid of academic private clouds and virtualised resources built around open standards and focusing on the requirements of the scientific community. The result is a new type of research e-infrastructure based on the mature federated operations services that make EGI a reliable resource for science. When using EGI Federated Cloud resources, researchers and research communities can count on:

After obtaining access to one or more sites of the EGI federated cloud, the prospective user can setup and operate custom services, applications and simulations within the virtualized hosting environments of these sites.

  1. Users select Virtual Appliances (a virtual machine image that encapsulates an operating system and optionally a set of applications) from the EGI Applications Database. Technical developers may also create their own images with any operating system of choice, the scientific software and any optional component needed for the software to function.
  2. Instantiate the Virtual Appliance(s) on the EGI cloud. Preferred API for EGI federated cloud is OCCI, which can be accesses using using a command-line client (rOCCI), high-level tools or directly implementing the ‘Open Cloud Computing Interface’ (OCCI) into your environment. OpenStack Nova API is also available for OpenStack sites belonging to the Federation.
  3. Users can use block storage (that can be attached as a disk to running Virtual Machines) or object-based storage that can be accessed from anywhere with the CDMI interface.
    • Tip: Read the storage how-to for more information on the storage services of FedCloud (PREPRODUCTION)
  4. Sites support the Virtual Organizations (VOs) and automatically download the Virtual Appliance lists endorsed by the VO managers.

Usage Models

The EGI Federated Cloud considerably widens the usage models supported by EGI. Now, web services and interactive applications can be easily integrated in the infrastructure, the computing environments can be finely tuned to satisfy user’s needs in term of software (OSs and software packages) and hardware (number of cores, amount of RAM, etc.) and, many solutions are available to store, update and access big amount of data. These new opportunities offered by EGI hugely extended the potential user base of the infrastructure opening the doors to new research communities with minimal or none knowledge of the EGI ecosystem.

We classified the usage models enabled by the EGI Fededated Cloud as follows:


Current FedCloud Users and Communities


More details of the FedCloud User Communities and their use cases is in the FedCloud Users Communities page.

How to use the FedCloud?

A brief description on how to use the FedCloud resources is described in the text below. More information can be found on the FedCloud FAQ page and the Guides and Tutorials listed in this page.

Quick Start

The typical user workflow on the EGI Federated Cloud looks like:

  1. Obtain a grid certificate from a recognised CA (if you don't own one already)
  2. Join fedcloud.egi.eu Virtual Organisation. This VO provides resources for application prototyping and validation. It can be used for up to 6 month for any new user.
  3. Select existing images from the Application Database Cloud Marketplace and start them by:
    1. Using one of the APIs and SDKs available, which include
    2. Using one of the high level brokering tools that are interoperable with the Federated Cloud.

Advanced Usage

Virtual Organisation

Once the 6-month testing period of fedcloud.egi.eu membership expires, you will need to move into a production VO:

Customized Virtual Appliances

You can prepare fully customised Virtual Appliances and deploy them to the sites:

  1. Prepare Virtual Machine Images (VMIs) that encapsulate your application. See the application porting tutorial for tips.
  2. Make the VMIs available online, for example in the EGI Appliance Repository
  3. Register the VMIs as Virtual Appliance in the EGI Applications Database (for howto please click here)
  4. Once your registered set of VMIs, bundled under a vAppliance version, have been published (see howto here),inform the Manager of your VO through Applications Database about the new Virtual Appliance (see howto here). He/she will include your images in the VO-wide image list, so these will be deployed on the Federated Cloud sites of your VO.

Guides and tutorials

These guides and tutorials help you to implement the above described typical user workflow and describe alternative ways of accessing, using high level application broker and infrastructure broker solutions:

Useful resources

Technical background

Cloud providers in the EGI Federated Cloud use hardware virtualization technologies to host software on their resources. The cloud management platforms that make this possible can vary from site to site, but they all enable the provisioning of virtualized computing, storage and networking resources, thus they empower scientific groups to setup and operate domain specific services, applications and simulations on these resources.

EGI Federated Cloud Sites

The EGI Federated Cloud sites are the resource providers. An overview of the resource providers, and their certification status (production status) is available here.

Interfaces and protocols

The EGI Federated Cloud is designed to satisfy scenarios defined by various scientific communities. The initial set of scenarios that the community collected has been distilled down to capabilities that the EGI Federated Cloud must provide to enable these community use cases. The capabilities were compared to state-of-the-art cloud computing technologies, standards, protocols and APIs to identify a technology stack which can help the National Grid Initiatives and research communities to connect resources into a federated infrastructure.
