What is a Network Load Balancer? Keeping Your Website Running Smoothly

💡A network load balancer distributes incoming traffic across multiple application servers to ensure scalability and a smooth user experience.

🌐Cloud-native architectures rely on load balancers to assign traffic and dynamically scale application servers based on their workload.

💰Load balancers can help optimize costs by dynamically scaling application servers and turning them off when not needed.

🔄Different load balancing algorithms, such as round robin, smart load balancing, and random select, offer different ways to distribute traffic among application servers.

📊Continuous monitoring and communication between the load balancer and application servers allow for efficient load distribution and management.

What is the purpose of a network load balancer?

—The purpose of a network load balancer is to distribute incoming traffic across multiple application servers, ensuring scalability and a smooth user experience.

How does a network load balancer help with scalability?

—By distributing traffic among multiple application servers, a network load balancer allows you to handle increased user load and scale your website as needed.

How do load balancers optimize costs?

—Load balancers can dynamically scale application servers based on their workload, allowing you to turn off servers when not needed and reduce costs.

What are the different load balancing algorithms?

—Some common load balancing algorithms include round robin, smart load balancing, and random select, each with its own way of distributing traffic among application servers.

How does communication between the load balancer and application servers work?

—Application servers constantly transmit data to the load balancer, providing information about their workload. The load balancer uses this information to make decisions on traffic distribution and server scaling.
