Hands-on

Why Alex Mattioli, former Director of Architecture for a global telecoms giant, chose to join ShapeBlue Hello, I’m Alexandre Mattioli – a Cloud Architect at ShapeBlue. After a few months working here I’d like to share some views. Originally from Rio De Janeiro, Brazil, I moved to Europe in my mid-twenties in order to pursue […]

CloudStack Feature First Look: KVM Rolling Maintenance

In a typical scenario prior to this feature, the administrator had to automate the process of setting hosts in maintenance before upgrading, usually using external automation tools. This feature allows administrators to perform the entire process within CloudStack, providing a flexible framework that allows defining custom scripts to execute on each host. CloudStack executes these scripts […]

CloudStack Feature First Look: Enable PVLAN support on L2 networks

Private VLANs have always been partially supported in CloudStack (for shared networks only), in versions prior to 4.14. Administrators could set up Isolated or Promiscuous PVLANs by creating their shared networks in which: Primary VLAN ID = secondary VLAN ID, for Promiscuous PVLANs Primary VLAN ID != secondary VLAN ID, for Isolated PVLANs CloudStack 4.14 […]

CloudStack Feature First Look: Direct Download agnostic of the storage provider

Introduction In a previous post, ShapeBlue’s Boris Stoyanov introduced a feature for KVM which allows administrators to register templates and ISOs without needing secondary storage as an intermediate cache. This feature is known as Direct Download in CloudStack. Without an intermediate cache, the templates and ISOs direct download registration process differs from the usual process, […]

CloudStack Feature First Look: Enable sending of arbitrary configuration data to VMs

This feature allows the sending of arbitrary additional VM configurations to user VMs on CloudStack and is supported by KVM, XenServer and VMware hypervisors. The administrator enables or disables this feature by the global configuration  ‘enable.additional.vm.configuration’ which is disabled by default. To add a second layer of security, the administrator must explicitly set a comma-separated […]

CloudStack Feature First Look: Hosts stuck in PrepareForMaintenance state

The process of setting a host into maintenance in CloudStack requires an administrator to ask for ‘prepare for maintenance’, either via API or through the UI on a host. When CloudStack receives the request to prepare the host for maintenance, the host state is set to ‘PrepareForMaintenance’ and any VM running on the host start […]

CloudStack Feature First Look: VR Health Checks

This feature introduces an easy and integrated way to check the health of virtual routers (VRs) within CloudStack. With the help of these checks, administrators can monitor VRs and take any necessary action when a failure is reported. These health checks can be basic or advanced. Basic health checks include: Connectivity from the management server to […]

Straight into the code

Hi – David Jumani here, maybe just a typical software engineer so far… I studied Computer Science and Engineering, and after graduation I worked at some of the biggest virtualization and networking companies (such as Vmware, Cisco and General Electric) developing cloud and on-premise applications, such as an incident co-relation engine (from which relationships can […]

CloudStack Feature First Look: Improvements for Template Direct Download

For some time now, CloudStack has supported the direct download of user templates for the KVM hypervisor. This basically allows user to register a template (whilst bypassing secondary storage) and directly download and install it to primary storage where it can be used for deployment: With CloudStack 4.14, this has been improved by adding direct […]

CloudStack Feature First Look: VM Ingestion

Apache CloudStack has proved itself to be a great cloud orchestrator and is probably one of the best open-source platforms available for deployment of new IaaS environments. However, until now there has been little or no support for importing an existing cloud environment with all its resources and entities into CloudStack. This is going to […]
