Load balancing

What is load balancing and how does it work?

Load balancing is the process of distributing requests across a pool of application servers. We provide HTTP/HTTPS (Layer 7) and TCP (Layer 4) load balancing service.

How a load balancer instance is created and how it is billed

You can create a new load balancer instances using a simple one-page wizard in the "Load Balancers" section of the Customer Portal. You will need at least one provisioned server to be able to create a load balancer.

Features specific to HTTP(S) load balancing

You need to specify at least one domain name to set up a load balancer instance in HTTP(S) (Layer 7) mode. The load balancer only processes requests to the configured domain names. HTTP/HTTPS requests with no domain name specified are dropped and the connection is closed.

Considerations on using multiple domain names with a single instance

You can add multiple domain names when creating a load balancer instance. At the same time, you will be able to add only one SSL certificate for the instance. This certificate will be used to respond to all request to that instance. Thus to protect multiple domain names you will need a wildcard certificate in case the domains are subdomains of the same 2nd level domain, or you will need a SSL certificate with SAN extension for multiple domains.

Access Logs

The "Logs storing" feature allows for logging information about requests processed by a load balancer to NGINX-style access log files. Logs are available in minute-long segments placed in the cloud storage of your Servers.com account. New files are added in batches of five every five minutes.
