In a multi-tenanted Enterprise Cloud deployment, every now and then, we face a situation where we wished we had more compute resource to service new requirements. Since capacity planning is not a fool-proof prediction of your growth, facing a resource crunch situation is inevitable. To mitigate this challenge, in this presentation, we will showcase techniques which you can use to run your cloud at maximum efficiency.
We will showcase how to make the entire deployment elastic by innovatively expanding and contracting memory / CPU overcommits without penalising performance.
We expect attendees will :
1. Learn about the Existing Overcommit techniques in various hypervisors and how they work
2. Learn about various techniques like Ballooning, KSM, Memory Compression and Transcendent memory.
3. Learn how to dynamically expand and contract VMs
4. Learn how to make Openstack to operate at maximum efficiency with minimum resources
