The OpenStack Havana release is now available with a number of new features geared towards the cloud
The OpenStack Foundation has now officially issued its latest release, code-named Havana.
The OpenStack Havana release includes new projects for cloud orchestration and monitoring and improves on existing compute, storage and networking capabilities.
Increased participation in the open-source project has led to new features being contributed and developed, Jonathan Bryce, executive director of the OpenStack Foundation, explained to eWEEK. OpenStack got its start three years ago as a joint effort of NASA and Rackspace and has since grown to include the participation and support of such leading IT vendors as IBM, HP, Cisco and Dell, among others.
One of the key new additions in the OpenStack Havana release is the inclusion of the Heat cloud orchestration project. Bryce explained that Heat enables a cloud administrator to describe a set of services that need to be deployed.
“Heat lets an application describe what it needs at a high level within a Heat descriptor file,” Bryce said. “Heat descriptor files can then be fed into an OpenStack cloud to provision the required resources.”
Different groups have already begun to experiment with Heat templates to rapidly provision and deploy cloud services, he said.
“You basically get a file, it tells you what software images are needed, identifies what installation commands must be issued, and it’s all packaged up in a single file,” Bryce said. “So you can now have a set of standard OpenStack clouds, take a Heat template, and you can now deploy the same application across all the clouds – it’s pretty powerful.”
Another new project that is being included in the OpenStack Havana release is the Ceilometer monitoring effort. OpenStack already had a dashboard component, known as Horizon, that provided visibility into cloud operations. Bryce explained that Ceilometer is a totally new service that is exposed right into the Horizon dashboard.
“What Ceilometer provides is a very high level of visibility into storage, compute and networking metrics,” Bryce said. “It aggregates all the information so an administrator can query an entire OpenStack cloud for information.”
With all that data, an enterprise or service provider can then pull usage data to bill users and customers for the services they have used. Going a step further, Ceilometer data can be pulled into the Heat orchestration system to enable auto-scaling of an OpenStack cloud based on usage and demand.
“Ceilometer provides a lot of really useful information that ties into many other systems,” Bryce said.
OpenStack Havana also introduces support for an increasingly popular form of virtualisation known as Containers. Until now, OpenStack supported virtualisation hypervisor technology including KVM, Xen, VMware ESX and Microsoft’s Hyper-V.
“Containers provide a less segregated virtualisation environment that is more efficient and requires less system overhead than hypervisors,” Bryce said. “Containers also offer the promise of improved performance.”
