The OpenStack operating system provides services used to manage (Figure 17-2):
• Instances’ Lifecycle (run, reboot, suspend, resize and terminate instances)
• Compute Resources (CPU, memory, disk, and network interfaces)
• Local Area Networks (Flat, Flat DHCP, VLAN DHCP and IPv6) through programmatically
allocated IPs and VLANs
• Who has access to compute resources and prevent users from impacting each other with
excessive API utilization
• Virtual Machine (VM) Images (store, import, share, and query images)
• Floating IP Addresses (assign and re-assign IP addresses to VMs)
• Projects and Quotas (allocate, track and limit resource utilization)
The following example shows the services interaction in an OpenStack environment.
