TechTarget defines scalability in an information technology context as “the ability of a computer application or product (hardware or software) to continue to function well when it (or its context) is changed in size or volume in order to meet a user need.”

Successful businesses are constantly growing, and their IT needs are constantly expanding as well. That is why it is essential to consider scalability when you are designing your business IT systems, including your databases and other business critical applications.

Database Scalability

Just two decades ago, the scalability of databases to very large sizes was legitimately in doubt, given the limited capacity of a single server, and the nascent techniques for connecting multiple servers were slow and experimental.

That has all changed today, with large enterprises constantly scaling up their databases to mind-boggling sizes given major advances in both hardware and software, especially multiprocessing DBMS technology. The main focus of scalability today has switched from how to scale up to size to how to optimize the scale up to assure as good or better performance.

Idera, a leading provider of application and server management solutions, fully understands the importance of scalability. The company’s flagship product SQL Diagnostic Manager has been designed around scalability from its inception, and SQL Diagnostic Manager 8.0 offers further scalability enhancements including easier and more in-depth monitoring, alerting and reporting of blocking sessions with real-time and historical views, and most importantly for scalability, a new feature allowing DBAs to undertake bulk diagnostic tests on multiple servers.
