Understanding the benefits and limitations of Basic Availability Groups can give you enough information to decide whether you would like to still use Database Mirroring regardless of its deprecation status or upgrade to Enterprise Edition to take advantage of all the Availability Group features. However, both options still put you at a disadvantage — the former being at the risk of using an unmaintained feature, the latter being more expensive.

This feature is not new and has been around since SQL Server 6. Highlighted below are the differences between the two that can help you make the right decision in choosing the appropriate high availability solution. While the comparisons apply to traditional Availability Groups as well, the focus will be on Basic Availability Groups.

A database is an object that resides within an instance. Understanding the difference between an instance and a database can help make decisions in implementing the appropriate high availability solution in terms of operational efficiency.

In an FCI, the entire instance is protected. If the primary node becomes unavailable, the entire instance is moved to the standby node. These instance-level objects are stored in the system databases which are physically stored in shared storage.

In an Availability Group — be it the traditional or basic — only the databases in the group are protected. System databases cannot be added to an Availability Group — only user databases are allowed. If all the dependent system objects are not replicated on all replicas, the database may end up becoming inaccessible to the application; as in the case of missing SQL Server logins or partially functional as in the case of missing certificates for Always Encrypted SQL Server Service Pack 1 made Always Encrypted available in Standard Edition.

If you are more concerned with instance-level protection to minimize possible human error during change management processes, then, an FCI is the way to go. An FCI requires some form of shared storage. The shared storage is accessible to all of the nodes in the failover cluster but only the current primary node has ownership at any given point in time.

The system and user databases are stored on the shared storage. When a failover occurs, ownership of the shared storage moves from the current primary to the standby, making the databases available to the new primary node. From a capacity point-of-view, you only need to provision disk space based on the sizes of the databases. However, from an availability point-of-view, the shared storage becomes a single point of failure.

The FCI will remain offline if the shared storage becomes unavailable, regardless of the number of nodes in the failover cluster. An Availability Group does not require shared storage. Put differently, this is a way to help minimize if not fully avoid downtimes. This functionality requires neither any additional hardware to use, nor the presence of a new cluster, and the upgrade process can be reversed unless you choose the “point-of-no-return”.

This edition is a good choice for companies with small-to-medium IT infrastructure that are seeking a robust and efficient system. As the name implies, the Datacenter Edition suits companies with heavy workloads, large virtual infrastructures, and high IT requirements.

To further maximize efficiency, set up a schedule of your backup jobs to ensure that you avoid overlaps and reduce the risks from manual handling. At the time of release, Windows Server provided the market with quite a wide range of new features. These include new functionality to enhance virtualization, administration, networking, security, storage efficiency, and so on.
