<br> The EGI Cloud federation is an hybrid cloud composed by public, community and private clouds, all supported by the EGI Core Infrastructure Platform services 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:
 
;Elastic computing infrastructure.
:Execute compute and data intensive workloads (both batch and interactive), host long-running services (e.g. web servers, databases or applications servers), or create disposable testing and development environments on VMs and scale your infrastructure needs over a federation of cloud providers. Select VM configurations (CPU, memory, disk) and application environments that better fit your requirements.
 
;VM image sharing and distribution
:Easily share and distribute VM images for your applications on a open library of Virtual Appliances. Community curated appliances are securely and automatically replicated accross the infrastructure. EGI provides a set of securely configured images with basic software ready to use on all providers that can be re-used and extended with contextualisation to execute your applications
 
;Unified view of federation
:The EGI Cloud provides: Single sing-on (SSO) for authentication and authorisation across all resource providers; Federated accounting with an integrated view of the the resource and service usage; Distributed information system for delivering a real-time view of the capabilities; and Federated monitoring to compute metrics for availability and reliability of the services.
 
;Beyond VMs
:Run docker applications on the EGI resources or use any of the supported PaaS and SaaS solutions that extend the IaaS capabilities of the EGI cloud and abstract the infrastructure to let you focus on your application development.

== 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:
 
*'''Service hosting''': the EGI Federated Cloud can be used to hosts any IT service as web servers, databases, etc. Cloud features, as elasticity, can help users to provide better performance and reliable services.
*'''Compute and data intensive''': applications needing considerable amount of resources in term of computation and/or memory and/or intensive I/O. Ad-hoc computing environments can be created in the FedCloud sites also to satisfy very hard HW resource requirements.
*'''Datasets repository''': the EGI Federated Cloud can be used to store and manage large datasets exploiting the big amount of disk storage available in the Federation.
*'''Disposable and testing environments''': environments for training or testing new developments.

== How to use the EGI Federated Cloud?  ==
 
=== Access  ===
 
EGI provides users with a single sign-on mechanism to access the federated services with the use of X.509 certificates and Virtual Organisations (VOs). Before using the EGI Federated Cloud you will need to:
 
*[http://www.egi.eu/how-to/get_a_certificate.html Obtain a grid certificate] from a recognised CA (if you don't own one already).
*Join [https://perun.metacentrum.cz/perun-registrar-cert/?vo=fedcloud.egi.eu 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.
*If you are part of an [http://operations-portal.egi.eu/vo/search existing VO] that has access to cloud resources, you may use that VO.
 
<!-- TODO: how to know if a VO has cloud resources?, which are those resources? -->
 
=== Creating your first VM  ===
 
The basic user workflow for starting a Virtual Machine (VM) looks like this:
 
#Browse in the [https://appdb.egi.eu/browse/cloud Application Database Cloud Marketplace] the available Virtual Appliances. Virtual Appliances  are the templates for the root volume of the running instances (Operating System and applications). EGI offers a set of basic images with minimal configuration that can get you started easily, but you can also find complete application stacks. See for example these images:
#*[https://appdb.egi.eu/store/vappliance/egi.ubuntu.14.04 EGI Ubuntu 14], a basic Ubuntu 14.04 image
#*[https://appdb.egi.eu/store/vappliance/egi.centos.6 EGI Centos 6], a basic CentOS 6 image
#*[https://appdb.egi.eu/store/software/compss.framework COMPSs], a VM for using COMPSs programming framework
#*[https://appdb.egi.eu/store/vappliance/biovel.portal BioVel Portal], for executing a biodiversity virtual e-Laboratory
#Read the description of the appliance for information on how to use it and connect to it once started.
#*You may need to have a ssh key in order to login into the VM, check [[FAQ10#How_can_I_inject_my_public_SSH_key_into_the_machine.3F|the FAQ on how to create one]]
#Get the IDs for starting the appliance at one of the sites supporting it in the "Availability and Usage" tab.
#Get the [[HOWTO11|command line client]] to start the VM using the IDs from previous step
#*Check the [[FAQ10#How_can_I_start_a_VM.3F|How can I start a VM?]] FAQ entry and the [[HOWTO11|command line client how to]] for more information.
#Connect to VM and start using it
#*You may need to allocate a public IP for the VM, check [[FAQ10#How_can_I_assign_a_public_IP_to_a_VM.3F|How can I assign a public IP to a VM]] in the Federated Cloud FAQ
 
=== Advanced topics  ===
 
==== API and SDKs access to Federated Cloud resources ====
 
Besides the command line client, there are several [[Federated Cloud APIs and SDKs|APIs and SDK ready to be used with the EGI Federated 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.
 
==== Storage ====
 
Every VM instantiated has a limited disk space provided with it, if you need more storage or need to share data, you can use a cloud storage solutions. There are two kind of services: Block Storage and Object Storage. Check the [[HOWTO09|EGI Federated Cloud Storage How To]] for more information.
 
==== Docker containers ====
 
You can [[Federated Cloud Containers|run your docker applications on EGI's Cloud]]. EGI also provides a [[Federated_Cloud_Containers#EGI_Federated_Cloud_clients_docker_image|docker image with the clients]] so you can test them easily.
 
==== PaaS/SaaS ====
 
Read in [[HOWTO10|this guidance]] about various options of porting applications to the EGI Federated Cloud that includes information on several [[HOWTO10#4._Infrastructure_broker_2|High level user environments to interact with the EGI Federated Cloud]] to manage your applications as VMs on cloud sites.
 
==== GPGPUs ====
 
'''PRE-PRODUCTION''' GPGPUs-enabled cloud resources are available in selected sites of the EGI Federated Cloud. Check the [[GPGPU-FedCloud|GPGPU guide on FedCloud]] for details on how to access them.
 
==== Customized Virtual Appliances  ====
 
You can prepare fully customised Virtual Appliances and deploy them to the sites:
 
#Prepare Virtual Machine Images (VMIs) that encapsulate your application. See the [[HOWTO10|application porting tutorial]] for tips.
#Make the VMI available online, for example in the [http://appliance-repo.egi.eu/images/ EGI Appliance Repository]
#Register the VMIs as Virtual Appliances in the [http://appdb.egi.eu EGI Applications Database] (for howto please click [https://wiki.appdb.egi.eu/main:faq:how_to_register_a_virtual_appliance here])
#Once your VA is published (see howto [https://wiki.appdb.egi.eu/main:guides:guide_for_managing_virtual_appliance_versions_using_the_portal here]),inform the Manager of your VO through Applications Database about it (see howto [https://wiki.appdb.egi.eu/main:guides:notify_virtual_organization_representatives 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.
 
==== Virtual Organisation  ====
 
Once the 6-month testing period of fedcloud.egi.eu membership expires, you will need to move into a production VO:
 
*Several other VOs of EGI make resources available from the Federated Cloud. Find a suitable VO in the [http://operations-portal.egi.eu/vo/search Operations Portal]. (Search for Cloud as a middleware type.)
*Existing grid production VOs can be extended by VO&nbsp;manager to cloud by declaring cloud resources in VO&nbsp;ID card (in Operations Portal) and requesting via [http://ggus.eu/ GGUS ](assign to Perun Support Unit) Perun support.
*If no existing VO suits your case, a new VO can be created. Please follow [https://wiki.egi.eu/wiki/PROC14_VO_Registration this procedure]. You can invite sites from the infrastructure to support them.

== 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 [[Federated_Cloud_Operation#Current_Resource_Providers|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.
