Device42 vs Google Cloud Migration Center

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.

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.
