Block Storage Cloud

This chapter is from the book ๏”€

Requirements

In this deployment scenario youโ€™ll once again be using the controller and compute nodes you created in Chapter 5, โ€œFoundations for Deployments.โ€ We will be creating a 10 GB volume group for use by Cinder on the controller and the minimum specifications defined in that chapter will easily support this.

Select Components

In addition to the foundational tooling, weโ€™ll be adding Cinder block storage to your deployment in this scenario. This will extend our very basic installation to have the following services. Their placement is demonstrated in Figure 8.1.

  • Compute (Nova)

  • Identity (Keystone)

  • Networking (Neutron)

  • Image service (Glance)

  • Dashboard (Horizon)

  • Block Storage (Cinder)
