![]() ![]() You have two options: scale up or scale out. When faced with a sudden surge in requests, your application will load slowly, the network will time out, and your server will creak. There is a limitation to the number of requests a single computer can handle at a given time. By implication, several load balancers will have to remain idle until there’s an increase in network traffic, for example, on Black Friday. Hardware-based load balancers typically require you to provide enough load balancers to meet increasing network traffic demands. While hardware-based load balancers require rack-and-sack, proprietary appliances, the software-based balancers are installed on virtual machines and standard x86 servers. Conversely, software-based load balancers run on standard operating systems and hardware (PCs, desktops). ![]() Hardware-based load balancers are physical hardware and are essentially dedicated systems (boxes) whose main purpose is to balance the flow of information between servers. Load balancers can either be hardware-based or software-based. ![]() One of the main goals of load balancing in the cloud is to prevent servers from breaking down or getting overloaded.
