Yes, but to make use redundancy you will always need a second server which means that another license is necessary.
We offer many packages but when purchasing a Bronze or Silver license from us you can buy a second license (which will be fully priced) to make use of redundancy but if you decide to go with our Gold or Platinum licenses then we offer a redundancy bundle, with this bundle the second license is half priced.
Buying a second license no longer becomes an issue if you go with our enterprise packages as they come with a second license included in the base price.
