- Hosting of virtualization systems: an heterogeneous variety of virtual machines can be installed and managed on the platform.
- High availability and clustering: machines on the cluster are externally monitored in order to guarantee the high availability in case of hardware or software failures.
- Distributed storage: data and disk images from the virtual machines are replicated and synchronized in order to guarantee its integrity and availability on the cluster.
- Intelligent virtual network: the virtualisation platform is capable of configuring and managing the network traffic in a data layer level.
- Administration: system can be easily configured and managed from a remote machine connected to the network as well as by an administrator on site.
- Automatic update: the virtualisation platform can be automatically updated from a remote server.
SEAPATH architecture
The virtualisation platform uses the following open source tools:
- QEMU: Emulator and virtualizer that can perform hardware virtualization.
- KVM: Linux module that offers virtualization extensions so the machine is capable of functioning as a hypervisor.
- Libvirt: virtualization API and management tool used to configure virtual machines simulated hardware.
- Pacemaker: High availability resource manager that offers clustering functionalities. It is used in combination with its plugins Corosync + STONITH.
- Ceph: Scalable distributed-storage tool that offers persistent storage within a cluster.
- Open vSwitch: Multilayer virtual switch designed to manage massive network automation in virtualization environments.DPDK
- : Set of libraries that provide a standard programming interface for packet processing on network function virtualisation and advanced network switching. This package is optional, it offers an optimized processing of the network packages at the cost of a hardware dependency (NIC must be DPDK compatible)
Ansible: Infrastructure management tool that simplifies orchestration of machines through declarative configuration.
A Yocto distribution
The Yocto Project is a Linux Foundation collaborative open source project whose goal is to produce tools and processes that enable the creation of Linux distributions for embedded and IoT software that are independent of the underlying architecture of the embedded hardware.
