If your infrastructure is already on Amazon, it simply makes the most sense to use a tool officially provided by them as an additional service, rather than having to rely on a third-party solution.

The process is now simplified because there won't be maintenance. Usually we can take a snapshot of the number I need. We can automate the backup snapshots and we can restore it very quickly. We get many benefits from the application.

For our simple requirement of migration, DMS is just a typical AWS RDS with an IPSec tunnel to Oracle. The most valuable features for us are the networking capabilities like VPCs and VPNs.

Improvements could be made in AWS Database Migration Service. Because of that, I am moving out of DMS now to a STRIIM solution.

One area that AWS DMS can improve on is its conversion of data types. For example, in Oracle, you have a data type called RAW, but in PostgreSQL there is no such thing. Thus, AWS DMS doesn't know what type I want to use when migrating from Oracle to PostgreSQL, and when performing the migration, AWS DMS changed the RAW data type to the byte data type, which isn't what I wanted.

Migrating from here and pushing the data from on-premise to AWS cloud is a big challenge and a few more services from AWS would be helpful. For example, we are currently using ILDB internet tools which move data from on-premise to the AWS cloud. A few more services would be really helpful for me to move the master data.

If they had some sort of functionality where, at a specific point in time, if I want to start a new job, it should automatically pick up from where it has been left rather than having people worry about the exact job number and the timing.

The names of the services need improvement since AWS doesn't indicate what the function of the product is presently. You need to read a lot to find the service that you want in the product.
