FIWARE Cloud provides advanced IaaS capabilities based on OpenStack, including Compute (Nova), Storage (Cinder), Network (Neutron) and Image (Glance) services. The services are available both via OpenStack APIs and via the FIWARE Cloud Portal. OpenStack Compute (Nova) service can be used to provision Virtual Machine instances by specifying the virtual machine configuration ‘flavor’ (from a catalogue of pre-defined flavors configured by the administrator) and virtual machine image, which comprise a pre-packaged Operating System and a software stack managed by OpenStack Image (Glance) service. FIWARE Lab holds a rich catalogue of Virtual Machine images, including base Operating Systems (such as Ubuntu or Red Hat) as well as images comprising pre-packaged installations of the various Generic Enabler implementations. It is possible to automatically customize the guest Operating System configuration on the first boot of the Virtual Machine, as well as to control the power state of the Virtual Machine (power on/off), suspend/resume, take snapshots, etc. The availability of some of the functions depend on the capabilities of the underlying virtualization layer. OpenStack Storage (Cinder) service can be used to provision persistent storage volumes, allocated from one of the storage pools configured by the administrator. These volumes can be then attached to a Virtual Machine instance, to hold persistent data of an application. OpenStack Network (Neutron) service is used to provision and manage virtual networks, which can be used to define connectivity domains and attach Virtual Machine instances to them, as well as virtual routers, used to control connectivity between virtual networks and with the Internet.
