The Apache CloudStack 4.18 cloud platform has been released, which allows you to automate the deployment, configuration and maintenance of a private, hybrid or public cloud infrastructure (IaaS, infrastructure as a service). The CloudStack platform was donated to the Apache Foundation by Citrix, which received the project after it acquired Cloud.com. Installation packages are prepared for CentOS, Ubuntu and openSUSE.
CloudStack does not depend on the type of hypervisor and allows using Xen (XCP-ng, XenServer/Citrix Hypervisor and Xen Cloud Platform), KVM, Oracle VM (VirtualBox) and VMware in one cloud infrastructure at the same time. To manage the user base, storage, computing and network resources, a web interface and a special API are offered. In the simplest case, a cloud infrastructure based on CloudStack consists of one control server and a set of computing nodes on which guest operating systems are organized in virtualization mode. More complex systems support a cluster of multiple management servers and additional load balancers. At the same time, the infrastructure can be divided into segments, each of which operates in a separate data center.
Release 4.18 is categorized as LTS (Long Term Support) and will be maintained for 18 months. Main innovations:
- Added support for "Edge Zones", lightweight zones typically tied to a single host environment (currently only hosts with a KVM hypervisor are supported). In Edge Zone, you can perform all operations with virtual machines, with the exception of operations with shared storage and console access, which require CPVM (Console Proxy VM). Direct-download of templates and use of local storage are supported.
- Support for autoscaling of virtual machines has been implemented (parameter βsupports_vm_autoscalingβ).
- Added API for managing user data.
- Added framework for two-factor authentication.
- Added support for authentication using time-limited one-time passwords (TOTP Authenticator).
- Added support for encrypting storage partitions.
- Integrated support for SDN Tungsten Fabric.
- Added support for Ceph Multi Monitor.
- Implemented API for accessing the console.
- Improved means of sharing access to the console.
- A new interface with global settings has been proposed.
- Provided support for configuring MTU for VR (Virtual Router) network interfaces. Added settings vr.public.interface.max.mtu, vr.private.interface.max.mtu and allow.end.users.to.specify.vr.mtu.
- Implemented adaptive groups for binding the virtual machine to the host environment (Affinity Groups).
- Provided the ability to define your own DNS servers.
- Improved toolkit to support guest operating systems.
- Added support for the Red Hat Enterprise Linux 9 distribution.
- The Networker Backup plugin is offered for the KVM hypervisor.
- The ability to set your own tariffs for traffic quotas has been provided.
- For KVM, support for a secure VNC console with TLS encryption and certificate-based access has been added.
