How does a load balancer allow a website to scale?

Load balancers allow you to distribute load (e.g. HTTP requests) between several servers. This is vital as it allows for horizontal expansion – you can increase your capacity (ability to serve x number of users) by simply adding more servers. Each web box will increase your capacity by 256 users.Click to see full answer. Also asked, how do you scale a load balancer?The most common ‘classical’ ways of scaling the load balancer tier are (in no particular order): DNS Round Robin to publicize multiple IP addresses for the domain. For each IP address, implement a highly available server pair (2 servers cooperating on keeping one IP address working at all times.)Subsequently, question is, how do you scale a web server? So, if we take this one step at a time: Step 1: Ease server load. Step 2: Reduce read load by adding more read replicas. Step 3: Reduce write requests. Step 4: Introduce a more robust caching engine. Step 5: Scale your server. Subsequently, question is, what is Load Balancer and how it works? In other words Load balancing refers to efficiently distributing incoming network traffic across a group of backend servers, also known as a server farm or server pool and for your kind information when a new server is added to the server group, the load balancer automatically starts to send requests to it.How do you load a webserver balance?Load sharing, or balancing, on multiple servers ensures that Web traffic doesn’t overload one server while other servers sit idle. To load balance Web servers, traditionally you use the DNS round-robin feature to evenly distribute Web server IP addresses to clients; thus, your Web servers are equally accessible.
