A single server is a physical machine and is not necessarily what you index (remote servers, virtual servers).
An individual or a non profit organization can download, install and use Alkaline for free. Alkaline server certificates are delivered on demand. Definition of a non-commercial company is available in the section called Definition of Non-Commercial Companies .
For example, FooBar , a non-commercial organization runs two Alkaline servers available at http://www.foo.org and http://www.bar.org at no cost.
Commercial companies and sites must buy Alkaline. The price is of 350.- US$ for the first server license and 150.- US$ for each additional one. Each separate server requires a license.
For example, FooBar , a commercial company, runs an Alkaline server for the external http://www.foo.com site and another two servers for the internal http://foo and http://bar sites at a total cost of $350.00 + 2 * $150.00 = $650.00.
Commercial companies reselling and/or offering commercial clients the search engine capability should purchase a full Alkaline license for the first server, an additional server license for each other server, plus an additional server license for each separate client.
For example, Foo , a web hosting company, runs two Alkaline servers for their three customers, Bar , Tender and Loin at a cost of $350.00 + $150.00 = $500.00 for the two servers hosted by Foo , plus 3 * $150.00 = $450.00 for their three customers for a total cost of $950.00.
Commercial companies offering their non-commercial clients the search engine capability should purchase at least a full server license.
For example, Foo , a web hosting company, runs two Alkaline servers for their three non-commercial customers, Bar , Tender and Loin at a cost of $350.00 + $150.00 = $500.00 for the two servers hosted by Foo and no additional cost for the three customers.
