Amazon Web Services has undoubtedly become a formidable presence in the cloud computing domain, despite growing competition from Microsoft, Google, IBM and others. To further cement its position, AWS has now launched its Database Migration Service which would allow the companies to easily migrate their current servers to AWS servers.
The service was first debuted in last year and was available in preview form. The company claims that since January 1, 2016, more than 1,000 databases have been moved to the AWS cloud.
Hundreds of customers moved more than a thousand of their on-premises databases to Amazon Aurora, other Amazon RDS engines, or databases running on Amazon EC2 during the preview of the AWS Database Migration Service,
said Hal Berenson, Vice President, Relational Database Services, AWS.
He also mentioned that the response to the AWS Database Migration Service was even stronger than their expectations.
In the preview, one-third of the database migrations used the AWS Database Migration Service to not only move databases to the AWS Cloud, but also to switch database engines in the process.
There are some problems faced by customers while moving their databases from one platform to other such as the risk of losing revenues during a shutdown while copying data, or difficulty in heterogeneous migrations between different database platforms (for example, Oracle to Amazon Aurora or Microsoft SQL Server to MySQL).
AWS Database Migration Service aims to solve these problems by promising these migrations with virtually no downtime. The service is simple to use with no need of installing any external applications or drivers and the whole process can be initiated within minutes by few clicks in the AWS Management Console.
Moreover, it ensures that all data changes to the source database that occur during the migration are continuously replicated to the target, allowing the source database to be fully operational during the migration process.
After the completion of migration, the target database will remain synchronized with the source and continue to function allowing the user to make the switchover at a convenient time. The cost of migrating will depend on the amount of data transferred. However, Amazon offers this service at a cost as low as $3 per terabyte of data.
The service is currently available only in eight geographical regions namely the US East (N. Virginia), US-West (Oregon), US West (N. California), EU (Ireland), EU (Frankfurt), Asia Pacific (Singapore), Asia Pacific (Sydney), and Asia Pacific (Tokyo) Regions. However, it is expected to be available to additional regions in the coming months.
