In this day and age, SQL Server licensing requirements are a complex topic with different license requirements across both Physical and Virtual environments in your SQL Server footprint.
At SQL Masters Consulting we are able to assist you in reviewing your current SQL Server footprint across both Physical and Virtual platforms and how these environments are affected by the various licensing terms.
If we are undertaking a Consolidation project for you or designing a new High Availability solution then your licensing requirements will be covered off as part of these pieces of work. If you are not sure what type of licensing you need then we can discuss and assist in guiding you in the right direction.
