Device42 vs Google Cloud Capacity Planner

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 Capacity Planner shows current and forecasted use of Google Cloud resources to help teams plan capacity and quota needs. It covers Compute Engine instances, Persistent Disk and Hyperdisk volumes, GPUs, TPUs, and Cloud Storage bucket egress bandwidth. Forecasts combine linear and superlinear models, with yearly seasonality for scopes holding at least two years of usage history. Compute usage is available at P50, P75, and P99 percentiles; Cloud Storage bucket usage is shown at P100 only. Historical usage spans up to two years, forecasts up to six months, and historical forecast snapshots up to one year. Usage is sampled every five minutes and displayed within 24 hours; Overview insights refresh at least every 48 hours. Data can be exported as CSV or through the REST API to Cloud Storage or BigQuery. The API supports project, folder, and organization scopes. The service costs nothing, but billable Google Cloud resources used with it are charged separately. It is in Preview under Pre-GA terms, may have limited support, and some organizations may need to request access.
