OpenStack design tenets focus on delivering essential infrastructure
on an available, scalable, elastic control plane
Basic Design Tenets
1) Scalability and elasticity are our main goals
2) Any feature that limits our main goals must be optional
3) Everything should be asynchronous. If you can't do
something asynchronously, see #2
OpenStack Leadership's vision statement
“essential Infrastructure, support platform”
4) All required components must be horizontally scalable
5) Always use shared nothing architecture (SN) or sharding.
If you can't Share nothing/shard, see #2
6) Distribute everything. Especially logic. Move logic to
where state naturally exists.
7) Accept eventual consistency and use it where it is
appropriate.
8) Test everything. We require tests with submitted code.
(We will help you if you need it)

computing platform
Key Capabilities:
Architecture
•Manage virtualized server resources
• CPU/Memory/Disk/Network Interfaces
•API with rate limiting and authentication
•Distributed and asynchronous architecture
• Massively scalable and highly available system
•Live guest migration
• Move running guests between physical hosts
•Live VM management (Instance)
• Run, reboot, suspend, resize, terminate instances
•Security Groups
•Role Based Access Control (RBAC)

Compute management stack control plane is built on queue and
database
Key Capabilities:
• Responsible for providing communications hub and
managing data persistence
• RabbitMQ is default queue, MySQL DB
• Documented HA methods
• ZeroMQ implementation available to decentralize
queue
• Single “cell” (1 Queue, 1 Database) typically scales from
500 – 1000 physical machines
• Cells can be rolled up to support larger deployments
• Communications route through queue
• API requests are validated and placed on queue
• Workers listen to queues based on role or role +
hostname
• Responses are dispatched back through queue

nova-compute manages individual hypervisors and compute nodes
Key Capabilities:
• Responsible for managing all interactions with individual
endpoints providing compute resource, e.g.
-- Attach iSCSI volume to phsyical host, map to guest as
additional HDD
• Implementations direct to native hypervisor APIs
– Avoids abstraction layers that bring least common
denomination support
– Enables easier exploitation of hypervisor
differentiators
• Service instance runs on every physical compute node,
helps to minimize failure domain
• Support for security groups that define firewall rules
• Support for
– KVM
– LXC
– VMware ESX/ESXi (4.1 update 1)
– Xen (XenServer 5.5, Xen Cloud Platform)
– Hyper V

nova-scheduler allocates virtual resources to physical hardware
Key Capabilities:
• Determines which physical hardware to allocate to a
virtual resource
• Default scheduler uses a series of filters to reduce set of
applicable hosts and uses costing functions to provide
Weight
• Not a focus point for OpenStack
– Default implementation finds first fit
– Shorter the workload lifespan, less critical the
placement decision
• If default does not work, often deployers have specific
requirements and develop custom
18

nova-api supports multiple API implementations and is the entry
point into the cloud
Key Capabilities:
• APIs supported
– OpenStack Compute API (REST-based)
– Similar to RackSpace APIs
– EC2 API (subset)
– Can be excluded
– Admin API (nova-manage)
• Robust extensions mechanism to add new capabilities

data about Users, Tenants and Roles
• Token service validates and manages tokens used to
authenticate requests after initial credential verification
• Catalog service provides an endpoint registry used for
endpoint discovery.
• Policy service provides a rule-based authorization engine
and the associated rule management interface.
• Each service configured to serve data from pluggable
backend

Image service provides basic discovery, registration, and delivery
services for virtual disk images
Key Capabilities:
• Think Image Registry, not Image Repository
• REST-based APIs
• Query for information on public and private disk images
• Register new disk images
• Disk images can be stored in and delivered from a variety
of stores (e.g. SoNFS, Swift)

citizen”.
• Follow design and style guide.
• Visual and interaction paradigms are maintained
throughout.
