Amazon Web Services Inc. (AWS), has added functionality to its Database Migration Service, (DMS), which allows enterprises to move their databases to the cloud seamlessly without downtime.
March saw the launch of the DMS. Jeff Barr, a spokesperson for AWS, stated that the AWS Database Migration Service involves setting up and managing a replica instance on AWS. This instance loads data from the source database and loads it into destination database. It can be used to perform a one-time or ongoing migration.
“DMS handles many of complex details associated with migration (Oracle to Aurora for example), including data type transformations and conversions from one database platform to the other. The service monitors the health and replication of the instance and notifies you if anything goes wrong. If necessary, it automatically provisions a replacement instance.
The service now supports continuous data replica, SSL endpoints, and the SAP ASE database (formerly SAP Sybase ASE).
AWS commented on continuous data replication support in a blog post. “Customers have the choice of enabling MultiAZ which provides a replica stream that is fault tolerant via redundant replication servers. Combining continuous replication with DMS’ ability migrate data between databases engines results in an exponential increase of possible use cases.
SQL Server, PostgreSQL and Amazon Aurora are all SSL-enabled endpoints.
The company also stated that DMS now supports SAP ASE… as a source or target for database migrations. Customers can now move data to or from ASE databases running on-premises, or in EC2. Data can also move between ASE and any other database engine supported by DMS, such as Amazon Redshift.
AWS stated that customers pay only for the use of compute resources during DMS migrations. This means that moving a terabyte-sized database could cost as low as $3.
