In their own words
Amazon Database Migration Service
Amazon Database Migration Service (AWS DMS) is a SaaS service for moving relational databases, data warehouses, NoSQL databases and other data stores to AWS or between cloud and on-premises environments. It handles one-time migrations and continuous replication, with support for both like-for-like and cross-engine moves. AWS says more than 20 databases and data warehouses can serve as source or target endpoints. DMS Schema Conversion assesses schemas and converts many code objects, including views, stored procedures and functions, while identifying work that needs manual conversion. DMS Serverless provisions and scales capacity according to transaction volume, billed hourly. Multi-AZ deployment uses redundant replication instances, and interrupted migrations can resume. API and AWS CLI support automation, while CloudTrail and CloudWatch Logs provide integrations. TLS, VPC deployment, PrivateLink and column masking are available. At least one endpoint must be Amazon RDS or EC2; on-premises-to-on-premises replication is unsupported. The AWS Free Tier offers free with credits.
Google Compute Engine
Google Compute Engine is an infrastructure-as-a-service product for running self-managed virtual machines on Google infrastructure. Choose a predefined machine type or configure a custom VM with 1 to 96 vCPUs and up to 8.0 GB of memory per core. Linux and Windows VMs are supported, with images including Debian, Ubuntu, FreeBSD, and Windows Server. Storage options include Persistent Disk and Local SSD. Managed instance groups can add VMs for peak load and replace underperforming instances; live migration can move a VM to another host in the same zone when its host goes down. Confidential VMs encrypt data in use, while Shielded VMs defend against rootkits and bootkits. The service integrates with Cloud Storage, App Engine, and BigQuery, and resources can be controlled through a REST-based API. Its free tier is free, within monthly limits and eligible US regions. Pay-as-you-go pricing is usage-based, with VM resources billed after a one-minute minimum in one-second increments.
