More and more companies are moving to the cloud, and Amazon is taking steps to make the transition easier.

On Tuesday, Amazon Web Services (AWS) launched the AWS Database Migration Service to help businesses shift their production Oracle Corp., Microsoft SQL Server, MySQL, MariaDB and PostgreSQL databases from on-premises data centers to AWS. In October, Amazon introduced the service. Since the start of 2016, more than 1,000 companies have used an early version of its migration service, AWS said.

Businesses are accumulating huge amounts data, and they need large computing power to analyze it. So, it makes sense that they would want to move it to the cloud, analysts say. It’s more efficient, and it costs less to do it there.

And more organizations are, in fact, moving to the cloud. A recent International Data Corp. survey found 58% of companies plan to use Web-based, on-demand computing services, including both public cloud and private cloud, for more than two applications. That’s an increase of 24 percent from 14 months ago.

The problem is shifting databases to the cloud can be complicated and time-consuming because of giant files that need to be copied and transferred to cloud data centers. And sometimes data analytics software has to be rewritten to make it compatible with cloud services. It can take large enterprises as long as two years complete a migration, Gartner analyst Lydia Leong said in a Wall Street Journal article.

According to AWS, the AWS Database Migration Service reduces the complexity, cost and downtime of database migration, making it possible for customers to migrate terabyte-sized on-premises Oracle, SQL Server and open-source databases to the Amazon Relational Database Service (Amazon RDS) or to a database running on Amazon Elastic Compute Cloud (Amazon EC2) for as little as $3/TB and with virtually no downtime.

Amazon’s news comes a week after Microsoft announced the next version of SQL Server 2016, its database program, would include software to ease the transfer of data from customer-owned servers to Microsoft Azure.

Oracle Corp. also has programs to help customers shift on-premise applications to Oracle Cloud.
