Scaling Options and SQL Server Performance Optimization
DBAs have the responsibility of maintaining and improving database production environments. This includes making the decision of whether or not they will scale the hardware systems. Many factors, including budgets and timeframes, make the decision even harder. It is not easy for DBAs to choose whether they would like to scale up or scale out.
Scaling up means to move databases and applications to a larger class of hardware with more powerful processors, more memory, and faster disk drives. Using higher levels of system resource could require you to scale up the production environment to be certain that end users are receiving the best experience.

To scale out basically means using federated servers to partition and replicate data across them. For example, CRM or ERP functionalities could be partitioned on different servers and horizontal data could be partitioned across several databases.
Consider SQL Server Performance Tuning
Prior to making that final decision on scaling up or scaling out, make sure that it is necessary. Performing the proper SQL server performance tuning can aid you in making that decision. Many performance and scalability problems can be solved by optimizing the SQL server. You should optimize SQL server databases and applications with wait time performance data and historical trend data before you decide to scale up or scale out.
SQL Server optimization can resolve performance bottlenecks like inefficient locking, unprepared SQL statements, poor indexes that lead to increased CPU loads, and memory or disk I/O utilization that are often incorrectly mitigated by scaling up on hardware.
Should You Scale Up Or Scale Out?
After you have done the proper SQL server optimization, and still are having performance problems, the next decision must be to scale up or scale out. It is common to scale up first. Even though scaling up may require significant expenditures, it is easier and more efficient than scaling out. Scaling up is essentially upgrading slower hardware with new, fast equipment and/or adding additional hardware components to the current configuration.
After scaling up and buying new hardware, you are still having performance issues, you will then need to look into scaling out with a federated server environment. Cutting back on the work each individual server must do will probably eliminate any performance issues that still occur.
Scaling out is also an option when budget constraints prohibit hardware scaling. If you have enough, or nearly enough, server capacity already, expenditures will be greatly reduced. The biggest decision here is deciding if the money saved is worth the increased complexity of managing a federated server environment.
Discover more benefits of SQL Server Optimization.
Start By Optimizing, Follow up by Scaling
It bears repeating that the most and least expensive performance enhancing optimization occurs at the application and database levels. You should be able to eliminate the need for scaling up or out if you focus server performance tuning on the database and application levels. Be sure to exhaust all optimization options before going through the expense and added complexities of scaling.
