Summary of Networking 101 - Load Balancers

00:00:00 - 00:05:00

Load balancers are used by companies to distribute internet traffic across multiple servers, allowing for better resource utilization and minimizing downtime. They enable websites to handle more connections and ensure that traffic is still served even if one server goes down. Load balancers also allow for maintenance and updates to be performed on individual servers without affecting overall service. They can use different algorithms to determine how to distribute traffic and can assess resource usage to make more informed traffic distribution decisions. Their main purpose is to efficiently distribute traffic among servers to ensure optimal performance.

• 00:00:00 In this section, the video explains the concept of load balancers and why they are used. Load balancers are used by companies to distribute internet traffic across multiple servers, allowing for better resource utilization and minimizing downtime. By hosting their website on multiple servers and using a load balancer, companies can handle more connections and ensure that traffic is still served even if one server goes down. Load balancers also allow for maintenance and updates to be performed on individual servers without affecting overall service. The video also mentions that load balancers can be used to add additional servers to handle increased demand, and that redundant load balancers are typically used for high availability.
• 00:05:00 In this section, the speaker explains the concept of load balancers in networking. Load balancers function by distributing traffic across multiple servers to prevent any one server from becoming overloaded. The load balancer can use different algorithms to determine how to distribute the traffic, such as "least connected" or "least loaded." The speaker mentions that load balancers can even assess the resource usage of each server, such as CPU load and memory, to make more informed decisions about traffic distribution. Overall, load balancers serve a basic purpose of efficiently distributing traffic among servers to ensure optimal performance.
