How Optimizing SQL Servers Can Reduce The Need For Scaling
There comes a time in every database production environment when you must decide whether or not to scale hardware systems. There are variables such as time frames and budgets that make this decision very difficult. It is not easy for DBAs to choose whether they would like to scale up or scale out.
To scale up means moving databases and applications to bigger and better hardware with more powerful processors, greater amounts of memory, and faster disk drives. Increased levels of system resource use might necessitate a scaled up production environment to be sure that end users are getting the best possible experience.
Get additional SQL Server Optimization information.
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.
Determine What Is Necessary
Before scaling up or out, you must be sure that it is required. Sufficient SQL server performance tuning could be a great help when making that decision. Numerous scalability and performance difficulties can be relieved with the proper SQL server optimization efforts. Scaling up or out should not be done until applications and SQL Server databases have been optimized using historical trend and wait-time performance data.
Many bottlenecks in performance like unprepared SQL statements, substandard indexes, and inefficient locking that contribute to greater workloads for CPUs and memory input/out use can be fixed with SQL server optimization instead of scaling up hardware systems.
Scaling Up or Scaling 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. Scaling up usually comes first. Even though scaling up may require significant expenditures, it is easier and more efficient than scaling out. Scaling up includes replacing slow hardware components with newer, faster ones and/or adding more hardware to existing configurations.
If scaling up still hasn't solved your performance problems, the next decision to make is to scale out and implement a federated server environment. Decreasing the workload on the individual servers will likely cure any performance issues that may remain.
If you don't have the funding to purchase new hardware (scale up), scaling out becomes a viable option. If you already have sufficient server capacity, your expenditures will be decreased dramatically. You must, however, determine whether the cost savings is worth the added complexity of running a federated server environment.
Discover more benefits of SQL Server Optimization.
Start By Optimizing, Follow up by Scaling
It is imperative to repeat that proper optimization at the database and application levels is the least expensive and most efficient way to enhance performance. Concentrating server performance tuning in those areas will commonly phase out the need for scaling. Make sure that you have tried every performance optimization option before you decide that scaling is the only way to solve your performance issues.
