Load Balancer Types

A load balancing type refers to the method or approach used to distribute incoming network traffic across multiple servers or resources to ensure efficient utilization, improve overall system performance, and maintain high availability and reliability. Different load balancing types are designed to meet various requirements and can be implemented using hardware, software, or cloud-based solutions.

Each load balancing type has its own set of advantages and disadvantages, making it suitable for specific scenarios and use cases

I guess there is a certain grouping here that is missing, something like:

Bucket A: The Implementation

  • 1. Hardware: A physical appliance.
  • 2. Software: A program (Nginx/HAProxy).
  • 3. Cloud: A managed service (AWS/Azure).

Bucket B: The Scope

  • 4. DNS Load Balancing: Global, before connection.
  • 5. GSLB: Global, smart DNS.
  • 6. Hybrid: Uses both DNS and Internal balancers.

Bucket C: The Logic (How does it route?)

  • 7. Layer 4: Routes based on IP + Port (Fast, Dumb).
  • 8. Layer 7: Routes based on Content/URL (Slower, Smart).

Is there any correlation between different load balancer types?

For e.g.

  1. Is DNS load balancer software or hardware?
  2. Is DNS load balancer L3 or L6?
  3. Are L3/L6 load balancer hardware or software?

Because all definitions seem disjoint and independent. Also what load balancing algorithm does each use?

For me both software & Layer 4/7 Load Balancers looks similar, could you please explain the differences?

I read that there is Gateway Load Balancer which operate on Layer 3. It is not defined in the content. Please explain if it is already defined with other names.
