There a many ways to use OnionBalance to increase the scalability, reliability and security of your onion service. The following are some examples of what is possible.
- SKS Keyserver Pool
- Kristian Fiskerstrand has set up a hidden service keyserver pool which connects users to one of the available hidden service key servers.
A popular onion service with an overloaded web server or Tor process
A service such as Facebook which gets a large number of users would like to distribute client requests across multiple servers as the load is too much for a single Tor instance to handle. They would also like to balance between instances when the ‘encrypted services’ proposal is implemented .
Redundancy and automatic failover
A political activist would like to keep their web service accessible and secure in the event that the secret police seize some of their servers. Clients should ideally automatically fail-over to another online instances with minimal service disruption.
Secure Onion Service Key storage
An onion service operator would like to compartmentalize their permanent onion key in a secure location separate to their Tor process and other services. With this proposal permanent keys could be stored on an independent, isolated system.
