An N+1 configuration is offered by utilizing a four-node failover cluster. And the company will call the cluster SQLCLUST.
After migrating these databases to SQLCLUST, the company requests to add a new identity column to most table in all of the databases so as to have a surrogate primary key supported. At the time the databases turn to production, the company requests to reset the seed value for all identity columns.
In order to get access to the Parts, Engineering, Customer, and Bids databases, the new Web services-based applications will be implemented. And the users will utilize their Windows credentials to access these applications.
