SQL Server's AlwaysOn technology makes it a great database tool

29 August 2013

In the modern business world, big data analytics is becoming a driver of corporate innovation. From helping marketing professionals gain valuable insight about consumer trends to helping businesses monitor efficiency, there are a number of uses for big data. 

However, the wealth of information required to use such technology can often put a strain on networks and servers. Therefore, it's important to have a flexible database solution in place that can allow IT professionals to create agile systems that make data sharing easy. 

Fortunately, tech workers with the right Microsoft training can help enterprises configure and manage SQL Server 2012, which comes with AlwaysOn services that allow for simple information exchanges. 

Within the AlwaysOn tool set are the Availability Groups that are useful mirroring features, according to SQL Server Pro. When it comes to mirroring, most server and database products are limited in capacity. Typically, this technology is confined to one failover partner. However, the source reported that the AlwaysOn Availability Groups offer support for a single primary replica, and also in as many as four secondary mirrors. 

Also, AlwaysOn is able to contain several databases that can be configured to failover automatically, protecting a number of servers at the same time. 

Another flexible option that AlwaysOn provides is the ability to use both synchronous and asynchronous replicas simultaneously. The former is useful for conducting high-availability scenarios that may require automated failover processes, while the latter is beneficial for disaster recovery operations.

Such configurations can support up to three different synchronous replicas, making it extremely easy for database administrators to manage a wide range of systems.

AlwaysOn in action
Microsoft recently highlighted how beneficial the AlwaysOn that is include in SQL Server 2012 can be. It cited the example of Mediterranean Shipping Company (MSC), which used AlwaysOn tools to enhance the firm's ability to access and share data with clients and employees across the world. 

The business plans to move a significant portion of its processing to secondary servers as it looks to increase the speed and efficiency with which it conducts data transfers. The company cited AlwaysOn as one of the major reasons why this change is possible. 

"With SQL Server 2012 AlwaysOn, we expect to shift 10 percent of the processing load from primary databases to secondary databases," said MSC executive, Fabio Catassi. 

By investing in SQL Server 2012 training, IT professionals can conduct procedures similar to those MSC is using to enhance data sharing. It's a worthy expense that can help enterprises in a number of industries establish more agile database setups.
