Database Load Balancing

Database Load Balancing Overview

Database Load Balancing Software is a mechanism for distributing load over a cluster of SQL databases. This is primarily achieved through replication, log shipping, and database mirroring.


Replication involves distributing load to geographically dispersed servers and then synchronizing them at a set frequency like overnight. Log shipping involves taking the transaction logs from the originating server, transferring them to the destination system, and restoring them automatically on a database that is in restore mode on the receiving server. Lastly, Database mirroring is used to mirror transactions to one standby server. In this case, the database on the standby server is in restore mode as in in the log shipping scenario. It's also possible to do snapshotting, where a snapshot of the database at a moment in time can be used for reporting and analytics. Notably, not every database load balancing tool offers all three of these solutions, most only offer one or two.

Database Load Balancing Comparison

When selecting a load balancing tool, one of the first things you should consider is whether you need a log shipping, replication, or database mirroring solution. Most database loading solutions don’t offer all three, and in fact, many only offer one. If your business needs multiple load balancing options, or all three, it is important to make sure you pick a solution that offers them. On the other hand, if you don’t need all 3 load balancing methods, you might be overpaying if you choose a solution that offers all of them.

Pricing

Pricing for database load balancing depends on how the service handles load balancing, and how many databases are covered. Most load balancing services charge an annual subscription, and businesses should expect to pay at least $1,500 per year. Most services also offer a free trial, so organizations can try a few services before locking in on one.
