AWS Schema Conversion Tool vs Google Cloud Migration Center

AWS Schema Conversion Tool (AWS SCT) converts database schemas between engines, including relational OLTP, data warehouse, and NoSQL schemas. If it cannot automate a conversion, it gives guidance for creating an equivalent schema in the target database. A project wizard estimates migration complexity for supported destinations and generates a report for comparing target options. For warehouse migrations to Amazon Redshift, it can manage data extraction agents; it can also create, run, and monitor AWS DMS endpoints and tasks. AWS SCT converts SQL embedded in C++, C#, Java, and other application code for users to review, edit, and save. Supported workload conversions include SSIS packages, Teradata workloads, and Apache Oozie workflows to specified AWS services. It is both a standalone, project-based application and a command-line tool. Planned converted schemas stay local until applied to the target. AWS SCT is free and supports 64-bit Microsoft Windows, Fedora Linux, and Ubuntu Linux. It also supports FIPS standards for connections to Amazon S3 or another AWS resource and is compliant with FedRAMP.

Google Cloud Migration Center helps plan moves from on-premises systems or other cloud environments to Google Cloud. It estimates future Google Cloud costs from existing resource sizes and configurations, and can inventory servers and Microsoft SQL Server, MySQL, and PostgreSQL databases. Assessments can report total cost of ownership, show application and network dependencies, and suggest destinations based on technical fit. Planning tools offer guidance on what to move and how, including rehost, replatform, and refactor strategies. Infrastructure information can be collected automatically once or continuously, or imported manually. Documented discovery covers AWS assets, Azure virtual machines in preview, and on-premises servers and virtual machines. A Linux and Windows discovery client can create offline reports without sending sensitive data to Google Cloud; the installed client itself runs only on Windows and does not discover databases. The service says it does not collect application or file-storage data. Estimates and assessments cost nothing, though other Google Cloud products may incur charges.
