Load Balancer Guideline

Guide:

• Useful with replication upon the usage of horizontal-scaling

• If virtualization model is adopted to the entire system, then the recommended load balancer will be Ngnix installed inside a Linux VM packed by Ubuntu Server LTS 64 bits version installation

• If containerization model is adopted to the entire system, then the recommended load balancer will be ingress-nginx with installation guide

• Load balancer is added in-front-of REST-API-services from the same type in production environment to route the requests from the proxy-component to them properly via LB.

  • Example:
    • LB_1 <-> RS-a_1, .., RS-a_N ;
    • LB_2 <-> RS-b_1, .., RS-b_N ;
    • ..
    • LB_N <-> RS-z_1, .., RS-z_N ;
