After a year of development, Apache CloudStack 4.12, the cloud platform, is now available. It automates the deployment, configuration, and maintenance of private, hybrid, or public cloud infrastructure (IaaS, infrastructure as a service). CloudStack was donated to the Apache Foundation by Citrix, which acquired the project after its acquisition of Cloud.com. Installation packages are available for RHEL.CentOS и Ubuntu.
CloudStack is hypervisor-agnostic and allows the simultaneous use of Xen (XenServer and Xen Cloud Platform), KVM, Oracle VM (VirtualBox), and VMware in a single cloud infrastructure. An intuitive web interface and dedicated API are available for managing the user base, storage, computing, and network resources. In its simplest form, a CloudStack-based cloud infrastructure consists of a single management server and a set of compute nodes that run guest operating systems in virtualized mode. More complex systems support the use of a cluster of multiple management servers. servers and additional load balancers. The infrastructure can be divided into segments, each operating in a separate data center.
Main innovations:
- For users of all types, the ability to create virtual networks at the data link layer (L2) is provided;
- Implemented support for remote debugging of control and production servers, as well as KVM agents;
- Added support for offline migration of environments from VMware;
- A command has been added to the API to display a list of control servers;
- Updated libraries used to build the web interface (for example, jquery);
- Expanded IPv6 supportThe ability to send data through a virtual router and calculate IPv6 addresses instead of issuing ready-made ones from a pool has been introduced. A separate set of filters, ipset, has been added for IPv6.
- For XenServer, support for online migration of unmanaged storages to managed storages has been implemented;
- For solutions based on the KVM hypervisor, support for Security Groups has been reworked, correct data on available memory is now transmitted to the management server, support for the influxdb database has been added to the statistics collector, the use of libvirt for I/O acceleration has been implemented, the VXLAN configuration script has been reworked, IPv6 support has been added, DPDK support has been enabled, and settings for running in guest systems have been added. Windows Server 2019, live migration of virtual machines with a root partition in file storage was implemented;
- The client interface provides the ability to edit the protocol in ACL rules;
- Added the ability to delete the local primary storage. In the properties of the network adapter, the display of the MAC address is provided;
- Support has been discontinued Ubuntu 14.04 (official support for LTS release) Ubuntu 14.04 ends at the end of April).
