The release of the Apache CloudStack 4.18 cloud platform has taken place, allowing for the automation of deployment, configuration, and maintenance of private, hybrid, or public cloud infrastructure (IaaS, Infrastructure as a Service). The CloudStack platform was contributed to the Apache Foundation by Citrix, which acquired the project after acquiring Cloud.com. Installation packages have been prepared for CentOS, Ubuntu, and openSUSE.
CloudStack is hypervisor-agnostic and allows for the simultaneous use of multiple hypervisors within a single cloud infrastructure, including Xen (XCP-ng, XenServer/Citrix Hypervisor, and Xen Cloud Platform), KVM, Oracle VM (VirtualBox), and VMware. A web interface and a dedicated API are provided for managing the user base, storage, compute, and network resources. In its simplest form, a CloudStack-based cloud infrastructure consists of a single management server and a set of compute nodes on which guest operating systems are virtualized. More complex systems support the use of a cluster of multiple management servers. servers The infrastructure can be segmented, with each segment operating in a separate data center.
Release 4.18 is categorized as LTS (Long Term Support) and will be maintained for 18 months. Key innovations include:
- Support for āEdge Zoneā has been added, which are lightweight zones typically tied to a single host environment (currently, only KVM hypervisor hosts are supported). In Edge Zones, all operations with virtual machines can be performed, except for operations involving shared storage and console access that require CPVM (Console Proxy VM). Direct download of templates and the use of local storage are supported.
- Support for autoscaling has been implemented. of virtual machines (the āsupports_vm_autoscalingā parameter).
- An API for managing user data has been added.
- A framework for two-factor authentication has been integrated.
- Support for authentication using time-limited one-time passwords (TOTP Authenticator) has been added.
- Support for storage volume encryption has been added.
- Integration of support for SDN Tungsten Fabric has been completed.
- Support for Ceph Multi Monitor has been added.
- An API for console access has been implemented.
- Access control mechanisms for the console have been improved.
- A new interface with global settings is proposed.
- Support for configuring MTU for VR (Virtual Router) network interfaces has been provided. Settings vr.public.interface.max.mtu, vr.private.interface.max.mtu, and allow.end.users.to.specify.vr.mtu have been added.
- Adaptive affinity groups for binding virtual machines to host environments have been implemented.
- The ability to specify custom DNS servers has been provided.
- The toolkit for supporting guest operating systems has been enhanced.
- Support for the Red Hat Enterprise Linux 9 distribution has been added.
- A Networker Backup plugin has been proposed for the KVM hypervisor.
- The ability to assign custom rates for traffic quotas has been provided.
- Support for a secure VNC console with TLS encryption and certificate-based access for KVM has been added.
