* Tidal Migrations is priced per business application equivalent. Statistics show the average number of business apps per organization varies from 10 to 200+, from small IT departments to large ones. Each application is assumed to be made up of a number of software components, virtual and physical servers and a single database. To calculate the number of business applications across a fleet of servers we use a ratio of 1:3. That is, absent of good application portfolio data, we estimate that for every 3 servers (operating system instances) you have 1 business application. Similarly, we estimate that each application has a maximum of one database instance. These ratios are calculated across your portfolio and serve to prevent abuse. For example, if you are on Small package, with a maximum of 20 applications, you can track up to 60 servers alongside your applications.
