This section explains L-Platforms.
An L-Platform is a logical resource used to collectively manage an entire system (platform) composed of two or more servers in a hierarchical system (Web/AP/DB), with a network.
The setting and the operation of two or more servers, storage, and networks can be simplified by the use of an L-Platform.
Resource Orchestrator can be used to deploy and operate L-Platforms.
An L-Platform defines the following combination of resources:
L-Server
An L-Platform is a logical server that manages physical servers and virtual servers (VM) together.
For details on L-Servers, refer to "2.2.3 L-Server".
Network Resources
This is a resource that expresses the network where it connects between L-Servers. Using network resources it is possible to automatically configure switches and virtual switches, and connect an L-Server to a network.
For details, refer to "2.2.7 Simplifying Networks".
Firewall Resources
In a hierarchical system, this resource ensures the security of each tier.
Server Load Balancer Resources
This resource distributes the workload across multiple servers, reducing the delay in response when there is concentrated traffic or server failure.
The configuration of an L-Platform is shown below.
