About Load Balancer Instances

The Apiculus Load Balancer Instances (LBI) Service allows Cloud Console users to create load balancer appliances, which are Linux Instances pre-loaded with a Citrix NetScaler VPX image. LBI can be used with VPC networks to achieve various traffic management features that are not possible using the standard VPC-based load balancing.

Public Load Balancer​

A Public Load Balancer is used to manage traffic that comes from the internet. It comprises a public IP address, allowing users or external systems to access your application from outside your network.

Use Cases​

  • Select this option if your application or service needs to be accessed from the public internet.
  • It is ideal for websites, public APIs, or any system where users connect directly from browsers or apps.

Placement​

  • It is placed in the web tier, which is a public subnet in your VPC.
  • It can forward traffic to backend instances located in either public or private subnets using routing rules.

Internal Load Balancer​

It works only inside your VPC. It has a private IP address, which means it is not accessible from the internet. It is used for managing traffic between internal services, like from your web tier to your application tier.

Use Cases​

  • Select this option when your services do not need public access but need to communicate within your VPC.
  • Useful in a multi-tier setup, where one layer of your application communicates to another.

Placement​

  • It is placed in the application or internal tier, which is a private subnet.
  • It routes traffic to backend services or internal logic components.
