Free IT Infrastructure Tools and Calculators
Infrastructure decisions often come down to one question: how many resources are needed, and which solution matches that need? The free tools on this page answer questions about GPU memory, server resources, backup storage and downtime cost in minutes. Each tool explains its formula and assumptions, so results are estimates you can check.
Calculations run in your browser; nothing you enter is sent to a server or stored.
Calculators
GPU VRAM CalculatorEstimates the GPU memory and number of cards needed for language models such as Llama, Qwen and Mistral, covering inference, LoRA and full fine-tuning.
RDS / ERP Server Sizing CalculatorEstimates Remote Desktop session hosts, vCPU, RAM and profile storage from concurrent users and workload type.
Backup Storage CalculatorEstimates backup storage from data size, daily change, restore points and copies, and scores 3-2-1-1-0 compliance.
Downtime Cost CalculatorEstimates the hourly and per-incident cost of IT downtime from revenue, affected staff and recovery time, and compares it with a target recovery time.
Rack Power and Space CalculatorEstimates kW load per rack, U requirement, circuit type for A + B feeds and heat load from your server and device count.
Cloud Migration Readiness AssessmentScores migration readiness with 11 questions, ranks the gaps and estimates data transfer time.
Ransomware Resilience CheckScores 11 core controls including immutable backup, MFA, remote access and monitoring, and lists priority steps.
KVKK Technical Measures ChecklistA 15-item self-check based on the technical measures in the KVKK Authority guide; print or save the result as PDF.
