What is scalability and how does load balancing work?

Scalability refers to a system's ability to handle increased load by adding resources. Load balancing distributes traffic across multiple servers to ensure no single server becomes overwhelmed.

Can you explain the different types of scalability?

Sure! There are two main types: vertical scalability (adding more power to a single server) and horizontal scalability (adding more servers to handle the load).

How does load balancing improve performance?

Load balancing improves performance by distributing user requests evenly across servers, reducing response time and preventing any single server from becoming a bottleneck.

What are some common load balancing algorithms?

Common algorithms include Round Robin, Least Connections, and IP Hash, each with its own method for distributing traffic.

When should I consider implementing load balancing?

You should consider load balancing when your application experiences high traffic, needs redundancy, or requires high availability.
