OpenStack Overview

• Cloud OS developed by Rackspace and NASA• Infrastructure as a Service• Support Private Cloud and Public Cloud• Open Source (Apache 2.0 license)• OpenStack Foundation• Popular and widely supported

What OpenStack provide?

Hardware RecommendationsRecommended hardware configurations for a minimum production deployment for the cloud controller nodes

Server Recommended Hardware Notes

Cloud Controller node (runs network, volume, API, scheduler and image services)

Processor: 64-bit x86

Memory: 12 GB RAM

Disk space: 30 GB (SATA or SAS or SSD)

Volume storage: two disks with 2 TB (SATA) for volumes attached to the compute nodes

Network: one 1 GB Network Interface Card (NIC)

32-bit processors will work for the cloud controller node.A quad core server with 12 GB RAM would be more than sufficient for a cloud controller node.

Two NICS are recommended but not required.

Hardware RecommendationsRecommended hardware configurations for a minimum production deployment for the compute nodes

Server Recommended Hardware Notes

Compute nodes (runs virtual instances)

Processor: 64-bit x86

Memory: 32 GB RAM

Disk space: 30 GB (SATA)

Network: two 1 GB NICs

Note that you cannot run 64-bit VM instances on a 32-bit compute node. A 64-bit compute node can run either 32- or 64-bit VMs, however.

With 2 GB RAM you can run one m1.small instance on a node or three m1.tiny instances without memory swapping, so 2 GB RAM would be a minimum for a test-environment compute node.

User/Tenant/Role

• User is a login name to OpenStack• Tenant or Project represents user capability

and resource quota • Role represent user’s authority over the

system

OpenStack Network Model

• Fixed IP is an internal IP address inOpenStack• Floating IP is Public IP address for external

accesses• Use Cases:

Use Case: Provider Router with Private Networks

Use Case: Per-tenant Routers with Private Networks
