Technical white paper | Product, solution, or service Executive summary This paper provides information about OpenStack clouds, describing a reference architecture that includes specific HP hardware with recommendations on how to set it up to implement a medium sized functional OpenStack cloud on the Ubuntu 14.04 LTS operating system release using OpenStack Icehouse software from the Ubuntu Cloud repository.

Technical white paper | Product, solution, or service What additional information will you need? The primary source of documentation is the OpenStack Foundation documentation available at http://docs.openstack.org/. The OpenStack Operations Guide provides invaluable insights and guidance to consider as you design and create your OpenStack cloud. You can also find information on installation, configuration, training, user guides, and even how to develop applications and contribute code.

Technical white paper | Product, solution, or service Cloud controller The cloud controller provides the central management system for multi-node OpenStack deployments. Typically the cloud controller manages authentication and sends messages to all the systems through a message queue.
PAGE 5
Technical white paper | Product, solution, or service For example, a cloud administrator might be able to list all instances in the cloud, whereas a user can only see those in their current group. Resource quotas, such as the number of cores that can be used, disk space, and so on, are associated with a project.

Technical white paper | Product, solution, or service service is deployed on OpenStack controller node in this reference design. For better scalability, it can be set up on dedicated networking node. Figure 2. Logical Architecture and Network Topology Logical model This reference architecture is implemented around the following logical model: • Basic architecture with Neutron networking.

Technical white paper | Product, solution, or service Hardware selection This section provides an overview of the hardware configuration using SL series hardware. Information about the roles and configuration of each server are provided. The SL series hardware we have chosen is ideal for OpenStack. The SL230 server configuration can support sufficient memory, processor, and storage to virtualize workloads well so we use it for our compute servers in this architecture.

Technical white paper | Product, solution, or service This install is done in 3 steps: 1. Install the MAAS server. 2. Install Juju. 3. Deploy Ubuntu Cloud Infrastructure with Juju. Installing the MAAS server 1. Follow the steps provided at http://maas.ubuntu.com/docs/install.html to install MAAS on one of the SL230 servers. Major setup steps include: • Install maas, maas-dhcp, and maas-dns packages • Create super user account • Import boot images • Setup DHCP service 2.

Technical white paper | Product, solution, or service 3. Adding an SSH key While you are still on the MAAS preferences page, add your SSH key by clicking Add SSH key. Use the public half of your SSH key, the content of ~/.ssh/id_rsa.pub for example; do not paste the private half ~/.ssh/id_rsa. 4. Deploy juju $ sudo apt-get install juju-core 5. Creating environments.yaml Create or modify ~/.juju/environments.

Technical white paper | Product, solution, or service Conclusion After understanding and working through the steps we have described, you should have a working small cloud that is scalable through the addition of compute and storage nodes. OpenStack is a complex suite of software and may be configured in many different ways. This reference architecture should provide a baseline for implementation and can serve as a functional environment for many workloads.
