Is it possible to combine all servers under one load balancer?

Yes, all servers can be combined under a single load balancer. The load balancer accepts incoming requests and distributes them among multiple servers, which can be physical machines, virtual machines, or containers.

This allows:

• Centralized traffic management.
• Increased fault tolerance: if one server is unavailable, the load balancer redirects requests to others.
• Scalability by adding new servers without changing the client side.

However, it is important to consider:

• The load balancer itself becomes a point of failure, so it should be made fault-tolerant (for example, using clustering).
• Properly configuring load balancing algorithms (round-robin, least connections, etc.) depending on the load and application type.

In the end, combining servers under a single load balancer is a standard practice for scalable and reliable systems.
