Amazon Database Migration Service vs Device42

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.

Device42 provides agentless discovery, asset management, and dependency mapping for data center, cloud, and hybrid IT environments. Its scope includes CMDB, DCIM, ITAM, IPAM, password management, and application dependency mapping, in a self-hosted deployment. It can discover network devices through SNMP and cloud resources across AWS, Azure, Google Cloud, Oracle Cloud, and OpenStack.

For data centers, its visual models cover buildings, rooms, racks, cabling, and patch panels, with power and temperature heat maps. Core includes discovery, inventory and asset management, integrations, REST APIs and webhooks, warranty and SSL certificate management, cable and password management, and IPAM. Device42 also tracks software licenses, contracts, and barcodes, and lists more than 30 integrations. Licenses count devices with IP addresses; non-IP assets do not count, and user seats are unlimited. If the device limit is exceeded, the software keeps running but stops collecting additional information until the license is increased. Pricing is available on request, and a free trial is offered.
