Google Cloud Capacity Planner vs ITRS Capacity Planner

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.

ITRS Capacity Planner is a SaaS platform for planning and managing IT infrastructure capacity. It uses machine learning and predictive analytics to assess future needs across physical servers, virtual workloads, and cloud workloads, and can identify application tiers constrained by capacity. Baseline View summarizes resource utilization; Forward Thinking lets users simulate changes and plan scenario stages over time. Reports can cover utilization over a selected period, metric relationships, server activity, and storage. Cloud cost tools compare Azure and AWS and provide right-size, right-buy, and optimization capabilities. The service integrates and normalizes data from multiple sources, including Geneos; documented collection types include AWS CloudWatch, Gateway Hub, vCenter, and file uploads. AWS collection can include instance properties, metrics, and costs. ITRS describes AWS data as segregated by customer and project and encrypted with AES. The software is chargeable, and a 30-day trial is listed, but no price is stated. Projects are configured during implementation by an ITRS account representative, who users must contact to change project settings.
