Throughout this document, specific terminology described in the following table is used to refer to different components of the VMware Integration OpenStack Services.
Table 1. VMware Integrated OpenStack Service Terminology
| Term | Description |
|---|---|
| VMware Integrated OpenStack Core Infrastructure | Core infrastructure referenced to the vSphere Infrastructure layer fundamental to run OpenStack services and instances. |
| VMware Integrated OpenStack | VMware Integrated OpenStack is a VMware supported full distribution of OpenStack that allows DevOps teams to use agile application methods for deployment and management of their applications. |
| VIO Manager | VIO Manager is the appliance that you deploy on vSphere Infrastructure to manage and deploy the OpenStack instance from the VMware vSphere Web Client. |
| Instance | Instance in this context of OpenStack reference to a vSphere virtual machine. |
| Glance | Glance is the OpenStack Image Service that VIO will set up. |
| Cinder | Cinder is the OpenStack Object Storage Service that VIO will be deploying. |
| Project | Project is equivalent of tenant or account. |
| Flavor | Flavor is a virtual hardware template in OpenStack. |
Table 2. VMware Network Virtualization Service Terminology
| Term | Description |
|---|---|
| VMware NSX® Manager™ | NSX Manager is the centralized network management component of VMware NSX that is installed as a virtual appliance on any VMware ESXi™ host in your VMware vCenter Server® environment. It provides an aggregated system view, a single point of configuration, and REST API entry points. |
| VMware NSX Virtual Switch™ | NSX Virtual Switch is the software that operates in server hypervisors to create a software abstraction layer between servers and the physical network. |
| VMware NSX Controller™ | NSX Controller is an advanced distributed state management system that controls virtual networks and overlays transport tunnels. |
| VMware NSX Edge™ | NSX Edge provides network edge security and gateway services to isolate a virtualized network. NSX Edge offers perimeter firewall, load-balancing, and other services such as SSL VPN and DHCP Relay. |
| Distributed logical router | VMware NSX for vSphere distributed logical router provides an optimal data-path for routing traffic within virtual infrastructure. Routes East-West traffic in a distributed fashion to provide better throughput and performance. |
| Distributed firewall | NSX for vSphere distributed firewall is a hypervisor kernel-embedded firewall at the virtual NIC level that provides visibility and control for virtualized workloads and networks. |
| VXLAN | Virtual eXtensible LAN uses a VLAN-like encapsulation technique to encapsulate MAC-based OSI Layer 2 Ethernet frames within Layer 4 UDP packets. Used in virtual networking to increase the scalability of the platform. |
