Deployed by thousands. Proven production at scale. OpenStack is a set of software
components that provide common services for cloud infrastructure.
What is OpenStack?
OpenStack is a cloud operating system that controls large pools of computing, storage, and networking resources throughout a datacentre, all managed and provisioned through APIs with common authentication mechanisms. A dashboard is also available, giving administrators control while empowering their users to provision resources through a web interface. Beyond standard infrastructure-as-a-service functionality, additional components provide orchestration, fault management, and service management amongst other services to ensure the high availability of user applications.

Overview of OpenStack features and benefits
|Leverages commodity hardware||No lock-in, lower price/GB.|
|HDD/node failure agnostic||Self-healing, reliable, data redundancy protects from failures.|
|Unlimited storage||Large and flat namespace, highly scalable read/write access,
able to serve content directly from the storage system.
|Multi-dimensional scalability||Scale-out architecture: Scale vertically and
horizontally-distributed storage. Backs up and archives large
amounts of data with linear performance.
|Account/container/object structure||No nesting, not a traditional file system: Optimized for scale,
it scales to multiple petabytes and billions of objects.
|Built-in replication 3✕ + data redundancy (compared with 2✕ on
|A configurable number of accounts, containers, and object copies
for high availability.
|Easily add capacity (unlike RAID resize)||Elastic data scaling with ease.|
|No central database||Higher performance, no bottlenecks.|
|RAID not required||Handle many small, random reads and writes efficiently.|
|Built-in management utilities||Account management: Create, add, verify, and delete users;
Container management: Upload, download, and verify; Monitoring:
Capacity, host, network, log trawling, and cluster health.
|Drive auditing||Detect drive failures preempting data corruption.|
|Expiring objects||Users can set an expiration time or a TTL on an object to
|Direct object access||Enable direct browser access to content, such as for a control
|Realtime visibility into client requests||Know what users are requesting.|
|Supports S3 API||Utilize tools that were designed for the popular S3 API.|
|Restrict containers per account||Limit access to control usage by users.|
The OpenStack Landscape
OpenStack is broken up into services to allow you to plug and play components depending on your needs.
The OpenStack map gives you an “at a glance” view of the OpenStack landscape to see where those services
fit and how they can work together.
