This document describes the management network connections for a distibuted HA cluster environment.
For a distributed environment, see Ports and communications
For a monolithic environment, see Monolithic ports and communications
Overview
Click on the diagram to display a larger version and open in a new tab or download to see a larger version. The information in this diagram is described in the following sections. The diagram shows a very large production system. However, the same connections between server components will be required in a smaller environment.
UI and API servers
The following diagram shows the Abiquo platform for a basic production environment. Users connect from the Internet or from another network environment to the UI and API servers. You can configure the UI and API servers and frontends in several different ways. The API and UI can be on the same host. See server and frontend configurations.
UI and API servers connect to datacenters and public cloud regions
The UI and API servers connect to the datacenters and/or public cloud regions, as shown in the following diagrams. Full details are given in the Connections section.
Servers table
The following table describes the servers used in the above diagrams.
Server | Description |
|---|---|
UI | Web server with the Abiquo UI. The entry point for other applications such as reports |
API | The Abiquo API supports HA/load balanced configuration |
M | Abiquo M streams events to the users. It is also the outbound API. Public access is not mandatory |
MySQL | Main Abiquo database and accounting. Can be hosted on Services/datanode server |
Services or datanode | This server hosts: Redis, Rabbit MQ. It can also optionally host zookeeper, which is required for API HA/loadbalancing. And it can also host MySQL. It may also be referred to as the “Datanode” server |
RS | Abiquo Remote Services except BPM. |
BPM | Abiquo BPM (V2V) converts templates to different hypervisor formats. Requires high IOPS |
NFS | NFS contains the available templates. Each Abiquo data center requires a share on the storage technology |
PRS | Abiquo public cloud remote services, including CPP, virtual factory, VSM and nodecollector |
Server and frontend configurations
The UI server proxy can be configured for connections to the other servers as shown in the following diagram.
API and UI frontend and load balancing
Both the API and the UI can be proxied and load balanced as shown in the following diagram. As we mentioned earlier, the UI and API can be on the same server.
Other connections
The other connections required between platform servers are shown in the following diagram.
