The document discusses the integration of multi-platform management with OpenStack, focusing on different deployment architectures, including single-node, multi-node, and distributed systems. It highlights the need for other platform architectures beyond commodity x86 hardware due to customer requirements, mentioning IBM System Z, Power Systems, and ARM microservers. Additionally, it outlines the benefits of co-locating workloads, consolidation strategies for reducing complexity, and details on IBM's OpenStack offerings and sessions at an event.

What concepts does OpenStack provide
to manage distributed, distributed cloud
deployments?
What are cells, regions, and availability zones, and how do I use them?

A cell comprises a
single API endpoint for
compute, allowing for
more fine-grained
scheduling across a
group of compute
nodes
OpenStack Segregation Constructs
Cell
Region
Availability Zone
Host Aggregate
Discrete regions contain
fully separate API
endpoints and provides
no coordination
between regions.
Regions can be used to
segregate specific
physical geographies or
datacenters
Availability zones are
used to handle logical
separation within your
nova deployment for
physical isolation or
redundancy. Zones are
useful for implementing
HA patterns at the
application level
Host aggregates allow
for segregated
scheduling given a
group of compute hosts
with common physical
features (e.g. storage
backend, specific
hardware capability)

Microservers, while fairly new on the scene, hold promise for significant data center size
reduction and energy efficiency. Pooling and shared resource for media serving, among
other uses, have a predicted 62% CAGR over the next four years.

Security
Performance and availability needs require co-
locating new zLinux cloud workloads with existing
extreme-throughput transactional systems.
• Designed for extreme scalability: sharing of high-speed network, CPU, and memory
• Core consolidation rates on average of 30-to-1
• Multi-system clustering; ability to assign 32 physical IFLs per LPAR
• System z designed from day one with high availability and failover implemented
• System z has highest SLA compliance rate of any platform in existence
• Availability components exposed in all higher “layers” – e.g. Linux networking
• LPAR design of hypervisor has complete isolation from all other LPARs
• Significant capabilities for logging, monitoring, auditing built into the system

Challenge:
• Hundreds of standalone servers; constantly increasing IT costs
• Growing system complexity and incompatibility, maintenance and
licensing issues
• Customer service and time to deploy suffering as a result
Solution:
Consolidate distributed servers and migrated mission-critical SAP and
DB2-based applications to an IBM System z running zLinux, zOS & zVM
Consolidation cut energy costs from 40%-80%
Baldor: reduced data center floor space from 6,000 to 1,000 sq. ft.
Both experienced significant reduction in system administration and maintenance costs
Customers: Consolidation on z yields significant IT benefits
