Implementing Failover in MS SQL Server 2017 Standard

Introduction

Often, we need to ensure fault tolerance of MS SQL Server DBMS, especially, when there is no Enterprise edition, but only the Standard one.

We would like to note that we are not going to examine the Express edition because there are significant restrictions to this instance. Sure, we can bypass some of them. For example, to resolve the issue with the database size of 10 GB, we can split a large database into smaller ones. To do this, we can create a new database based on a certain property, and combine the selections from the same tables of different databases in the views in the principal database. However, fault tolerance in the Express edition will be performed either by a system administrator or by using your own or third-party software.
