Select Right Data Replication Software to Increase Business Efficiencies

There will always be a million reasons why you’ll need a real-time data replication solution. But regardless of what is driving your requirements, you’ll have to choose the right tools if you’ve to increase your operational and business efficiencies. There are two sides to it – on the positive side you have many choices when it comes to the variety of tools available and on the other, you must make the right choice which is not easy. This post is a step-by-step guide to help make the right selection. The first step as in any technology selection is to first define requirements and how you intend to use the data replication tools. Points to consider are the number of sources and targets and whether they are standardized or heterogeneous, how much data is involved and the type and frequency of data that has to be replicated. Another critical factor is how frequently sources and targets will be added, changed, or taken offline and the security requirements. After this step, the selection process of the data replication tools has to be initiated. There are two you can opt for. The first is leveraging replication technologies that are built-in or sold with specific databases. Some of these include Microsoft SQL Server Replication and Oracle Streams. Another choice is to use a purpose-built, best in class data replication tool. 

The point is which you should select. When you are generally replicating light volumes of data across a few identical databases, a native replication tool will fully serve your purpose. But on the other hand, if you need to synchronize large volumes of data across several heterogeneous systems with robust requirements of reliability, high-availability, and security, you have to focus on purpose-built, best-of-breed tools.

At first thought, it is natural that you’ll want to start and end your evaluation of data replication tools with the top-end ones only. But before jumping to a conclusion, it is advisable to carry out due diligence of all the options to match specific tools with your needs.

Log-based CDC – Some replication tools depend on even-based processing and triggers and are invasive and impose significant overheads. However, log-based Changed Data Capture (CDC) is widely recognized as a superior approach because it minimizes the load on sources and targets and is quite easy to set up and maintain. Initial data load – Top class data replication tools should also feature online data load to initially load target databases. These will compare and provide repair capabilities to ensure that sources and targets always remain in sync. Cost – Apart from the initial license cost, check on the ongoing expenses associated with training and administration. As you research more, you will find white papers and documents on various types of data replication tools.
