CloudStack VMware environment Migration from vSwitch to dvSwitch | CloudStack Feature First Look
Introduction The networking in VMware environments is managed by either standard virtual switches (vSwitch) or distributed virtual switches (dvSwitch). These switches handle the traffic between Instances and the Physical Network. A standard vSwitch needs to be created per-Host, which means that each time a Host is added to a VMware Cluster, a standard vSwitch must […]
Host Control Plane Status I CloudStack Feature First Look
Introduction Diving into the ever-evolving world of Apache CloudStack, it is undeniable that its continuous enhancement has led it to become an influential infrastructure management platform. The recent feature addition, ‘Host Control Plane Status’, further refines this powerful tool by extending the hypervisor host control state in the listing of Virtual Machines / VMs (ie. […]
State of the Hypervisor Market
In the ever-evolving realm of virtualization, hypervisors are a fundamental technology enabling the management of virtual machines. The choice of the underlying hypervisor for CloudStack-based clouds is one of the most important architectural decisions to make, impacting everything from resource utilisation to IT budgeting and the ability to adapt to future technological shifts. Unlike other […]
Adaptive Affinity Groups l CloudStack Feature First Look
In Apache CloudStack, Host Affinity and Host Anti-Affinity refer to the ability to deterministically ensure that a set of Instances run on the same or diverse hypervisor hosts in order to meet specific workload needs. How Affinity Groups Worked Previously Before Apache CloudStack 4.18 there were two types of Affinity Groups: Host Affinity and Host […]
Secure KVM VNC Connections l CloudStack Feature First Look
Introduction In a previous blog post (https://www.shapeblue.com/api-driven-console-access/) we described the latest improvements around VNC console access in CloudStack 4.18. These improvements included switching it to an API-driven approach, and introduced a way to secure WebSocket traffic between the CPVM and end-users, whilst the traffic between the CPVM and hosts remained decrypted. This blog post explains […]
VMware Abstraction Using Apache CloudStack
The hypervisor market is in a state of flux. For over a decade, VMware has entrenched itself as the gold-standard virtualisation platform for enterprises. However, their relentless march for revenue, expected to deepen by announcements earlier this year, has led many users to reconsider their long-term strategy. In the service provider space, the weight of […]
CloudStack vs. OpenStack Comparison – What you need to know before choosing a cloud management system
Infrastructure as a Service (IaaS) is recognized as facilitating speed-to-market and for its ability to drive business agility. When a company demands specific answers to a business problem, the answers lie in a jumble of calculations, including investments and platform operation and maintenance. Apache Cloudstack and OpenStack are two widely-known Cloud Management Platforms that can […]
Improvements to VM and Volume Migration | CloudStack Feature First Look
Migration of resources such as virtual machines and volumes is essential functionality for cloud operators, enabling them to load balance or perform maintenance operations on underlying compute, storage or network resources without major downtime. CloudStack provides impressive functionality to migrate VMs and volumes, with different APIs for different use-cases: migrateVirtualMachine migrateVirtualMachineWithVolume migrateSystemVm migrateVolume Learn how […]
Granular Control of Dynamic Scaling of VM’s CPU/RAM
Currently, CloudStack allows admins to configure the dynamic scaling of CPU and RAM for the VMs using a global or zone level setting “enable.dynamic.scale.vm” and through a “Dynamically Scalable” flag in templates. However, the global or zone setting applies to all VMs in a particular region or zone and there may be virtual hardware or […]
Import Virtual Machines in CloudStack
Since CloudStack 4.14 it has been possible to import virtual machines (VMs) from a vSphere cluster directly into CloudStack, which introduced the concept of managed and unmanaged VMs. Managed VMs are those controlled by CloudStack, whereas unmanaged VMs have been either deployed directly on the hypervisor or removed from CloudStack (using the unmanageVirtualMachine API). To […]
