What is a Load Balancer?
Load balancers are crucial infrastructure components that distribute network traffic across multiple servers, enhancing scalability, reliability, and performance of applications by preventing server overloads and enabling dynamic resource scaling.
MAIN POINTS FROM TRANSCRIPT
- Load balancers distribute network traffic to prevent server overloads, ensuring consistent application performance.
- They enable dynamic scaling of applications by adding or removing resources based on demand fluctuations.
- Different types include hardware, software, cloud-based, and global server load balancers, each with unique benefits.
- Layer 4 and Layer 7 load balancers operate at different network layers, offering speed or content-based routing capabilities.
TAKEAWAYS
- Load balancers improve application availability by providing redundancy and failover options.
- They reduce latencies and improve response times by intelligently distributing requests.
- Layer 7 load balancers offer advanced features like SSL termination and content-based routing.
- Global server load balancers enhance resilience and low-latency access for global applications.
