![]() ![]() The same editions comparison pages listed above include this information also. Unlike feature differences this will not cause your code to fall over because things are missing in production that are present in development, but it might cause performance differences. The differences beyond features between the editions and licensing options are how much RAM and how many CPUs/cores are supported. You could also go the other way: if you don't specifically need greater feature set and your dev environments don't have the data size to need more RAM than it will make use of, make your devs use Express instances then you know they won't use anything that won't be present when you deploy to Standard! The risk here is small, and can be mitigated with care. To see which features this affects, check MS's editions documentation: 2012, 2014, 2016, 2017. The risk here being that one of your devs may make use of a feature that is not enabled in production. For instance table level data compression was not supported outside enterprise (and developer) editions before 2016sp1 (including the original release of SQL Server 2016). If you are using an older version then there might be differences to watch out for. If you are using SQL Server 2016sp1 or above then this is unlikely to be a problem at all: almost everything is available to all editions. The problems you could hit are that some features might not be enabled in your production, standard edition, installation that are present in your development environment. ) and your level of aversion to the small risk.ĭeveloper edition is essentially Enterprise edition under a different licence. It needs its own Enterprise licence.Mostly no, it isn't dangerous, but it depends on which version of SQL Server you are talking about, what parts you are using (just the DB engine?, SSIS?, SSRS?. This instance is used (reporting) and host several databases. If this instance is used and accessed (reporting, backups, etc.) or is not covered then it also need it own Enterprise licence.Or performing any “work” such as additional backups from secondary servers, then it must be licensed for SQL Server. If it is serving data, such as reports to clients running active SQL Server workloads, The passive secondary server used for failover support does not need to be separately licensed for SQL Server as long as it is truly passive. If this instance is really passive, then it may already be covered by the licence on instance 1 as a free passive server:īeginning with SQL Server 2014, each active server licensed with SA coverage allows the installation of a single passive server used for fail-over support.This is your main instance with several databases. Please note that since SQL Server 2016 is not yet available, some of the links and information are based on SQL Server 2014 licencing model. Licensing Datasheet and then check and discuss it with you software vendor. You should review SQL Server 2014 Licensing Guide and SQL Server 2014 HA aside, if Instance 1 is using a single Enterprise option, then an Enterprise licence is needed on all 3 instances. Therefore a Standard licence does not seem to be an option in your case. You will then fall under the other restrictions of Basic AG and you won't be able to use more than 2 replicas, hence no instance 3. ![]() However you will have to create them using the WITH BASIC option. You could create X Availability Groups for your X databases with a single database in each AG. ![]() Some of these restrictions are ~similar~ to the deprecated mirroring functionnalities.īecause you are consolidating servers and instances, you obviously have several databases. Limit of two replicas (primary and secondary).Now using Standard edition with only a Basic High Availability group is posible with some of the limitations found on Overview of AlwaysOn Basic Availability Groups (SQL Server): Since you are consolidating several instances and servers, you should also look at other restrictions such as collation, etc. If you look at Prerequisites, Restrictions, and Recommendations for AlwaysOn Availability Groups (SQL Server) you will find a similar restriction among others:Įach server instance must be running the Enterprise Edition of SQL Server 2016. ![]() If you look at the 2nd row from the bottom of the Compare edition table (SQL Server 2016) on SQL Server Editions page, only the Enterprise edition includes this:Īdvanced high availability (AlwaysOn, multiple, active secondaries multi-site, geo-clustering) You can look for SQL Server 2014 Capabilities at the top of page 5: SQL Server 2014 Licensing Guide.
