mCloud offers a basic software layer 4 load balancer that runs from within our software-defined networking layer. This guide details the steps required to configure a load balancer in the Cloud Dashboard and offers an explanation of its capabilities and limitations.

Please note that to access this service, you will need to request access from the Micron21 Support Team.

Capabilities:

mCloud LBaaS can handle the following types of traffic:

• TCP/UDP

• Source IP/Port load balancing

mCloud LBaaS is unable to be configured with the following configurations

• Layer 7 load balancing (HTTP, HTTPS etc)

• Round robin or least connection load balancing
