Multi-cloud infrastructure
At the beginning of May, the speakers & moderators of the event organized by Canonical went to the Italian virtual space and enjoyed the presence of experts from DXC, GARR, and Canonical, who shared with us their knowledge about multi-cloud infrastructure.
During the event, our speakers discussed about:
- Enterprise infrastructure: challenges around scalability and TCO
- Leveraging automation: OpenStack, Kubernetes and Kubeflow
- Price to performance ratio optimization case studies
Q& A about Kubernetes, Openstack and BootStack
Unlike other events, during the event that took place on 12nd of May 2021, we valued the interaction of our participants and we had multiple Q&A questions, creating an engaging environment.
Throughout the event, the speakers received various questions around the topics that they approached. You can read some of them below.
Have you ever migrated VM instances from VMware to OpenStack?
There are specific commercial products that allow migration from existing VMware or Openstack infrastructures to Charmed Openstack/PCB. For example Cloudbase Coriolis (partner of Canonical). You could read more about VMWare to OpenStack migration in this whitepaper. (Available also in Italian)
Is it worth installing Kubernetes on Openstack, or is it more convenient to create a separate infrastructure?
It depends on the use case. Very often it is more flexible to install CDK on an existing Openstack to take advantage of flexibility in terms of scale-out and resource allocation.
How many servers are needed to install Charmed Kubernetes?
For Charmed Kubernetes and MicroK8s, the minimum number of servers (VM or bare-metal) to have an HA configuration is 3. As another environment option, Charmed Openstack gives more configuration flexibility. MicroK8s is more suitable for Telco/Edge or IoT projects. Both are 100% upstream Kubernetes. Please refer to Canonical’s Kubernetes solutions website for more information.
