Arthur Berezin, a senior technical product manager at Red Hat, presented on OpenStack and its functionalities, highlighting its modular architecture for cloud-enabled workloads and seamless scaling. The presentation discussed various OpenStack core projects, including compute, image, object, networking, and storage services, all aimed at improving cloud infrastructure management through a community-driven approach. Furthermore, the Red Hat OpenStack platform is designed for enterprise use, facilitating long-term deployments with support and certification through Red Hat's partner network.

I believe in “Free As in Speech”
vs. “Free As In Beer”

3. But “Free As in Beer” is also OK

4. VIRTUALIZATION
INFRASTRUCTURES
●
●
●
●
●
●
●
●
Greater server utilization
Less server sprawl
Minimize space & power
Higher staff productivity
Business continuity
Fault tolerance and HA
Extended service levels
Lifecycle management
PRIVATE & HYBRID CLOUD
INFRASTRUCTURES
●
●
●
●
●
●
Self service
Automated provisioning
Charge-back and quotas
Workload portability
Disposable resources
Heterogeneous management

5. CLOUD
WORKLOADS
TRADITIONAL
WORKLOADS
●
●
●
●
●
●
●
Stateful VMs, application = VM
Big VMs: vCPU, vRAM, storage
inside VM
Application SLA = SLA of VM
Lifecycle measured in years
VMs scale up: add vCPU, vRAM,
etc.
Applications not designed to
tolerate failure of VMs
●
●
●
●
●
●
Stateless VMs
Small VMs: vCPU, vRAM, storage
separate
Application SLA <> SLA of any one
VM
SLA requires ability to create and
destroy VMs where needed
Lifecycle measured in hours to
months
Applications scale out: add more
VMs
Applications tolerate failure of VMs

6. PETS =
TRADITIONAL WORKLOADS
●
Pets are given names like
●
FARM ANIMALS =
CLOUD WORKLOADS
rover.internal.redhat.com
●
●
●
They are unique, lovingly
hand raised and cared for
●
When they get ill you nurse
them back to health
●
Farm animals have tag
numbers like
piggie242.redhat.com
They are almost identical
to each other
When they get ill you get
another one

8. OPENSTACK
