We have an application and for each customer we provision a new namespace. There are two deployments running inside a single namespace:
The front-end should be accessed by the users hence we are using LoadBalancer for each customer (We have a VM Based k8s cluster).
The problem is, as of now we have a few customers and when the business grows, the customers will be increasing and will be having more NameSpaces.
For example: If there are 100 Users, we have to have 100 LoadBalancers. This is not practical and can we have a single LoadBalancer instead and allow all the 100 Users to access through that LoadBalancer?
Can we do this using Ingress?

Main benefits of using ingress are:
and many more.
You can choose an ingress which fits better for your use-case. Ingress options
