Column	Values	Rules triggered
ENV	Production / Staging / Dev / Test	1a Burstable excluded (Prod/Staging) · 1b Current-gen only (Prod) · 1c No nano/micro (Prod/Staging) · 1d ≥4 vCPU for DB/Web workloads (Prod)
OS	Linux (default) / Windows / macOS	Windows → ARM/Graviton excluded · macOS → mac1/mac2 families only
Workload	General · Database · SQL Server · Web Server · Cache · ML/AI · Batch · HPC · SAP	Preferred families sorted first: Database→r/x/z · SQL Server→r/x/z · Web→m/c · Cache→r/x · ML/AI→p/g/trn/inf · Batch→c/m · HPC→hpc/c · SAP→x1/x2/r/u-
Compliance	PCI / HIPAA / FIPS	1b Current-gen only · Nitro Enclaves required (AWS PCI/HIPAA)
Min Gen	5 / 6 / 7 (generation number)	Excludes instance generations older than the one given (e.g. 7 → only m7i/c7i and newer)
Exclude	Comma-separated type names (e.g. Burstable,GPU)	Excludes those instance types for this row only — quote the cell when it names more than one

All columns are optional — blank cells use safe defaults (Linux, General workload, no ENV restrictions).

Current Instance Type fires no rule and does not affect sizing by default — only in cloud-to-cloud mode does a row without CPU Count / Memory (GB) get sized from it. It records what the VM runs on today (e.g. m5.xlarge) and is carried through to the preview and every export, beside the recommendation that would replace it.

Recommendation Type

Like-to-Like Recommendation
Recommends instances with equal or higher CPU and memory (cheapest option)

Optimized Recommendation
Recommends instances based on actual utilization data

Both
Generates both like-to-like and optimized recommendations

🧠 Optimization Settings

Size against: Averages hide bursts: a VM averaging 20% with a p95 of 85% is not a downsize candidate. p90, p95, p99 and Peak use the matching CSV columns; a row without them falls back to what it has, and the basis used is reported per row in the Sized On column.

Optimization Mode:

CPU-Based

Memory-Based

💻 CPU Utilization Ranges:

CPU Downsizing (N-1): % to %

CPU Keep Same (N): % to %

CPU Upsizing (N+1): % to 100%

🧠 Memory Utilization Ranges:

Memory Downsizing (N-1): % to %

Memory Keep Same (N): % to %

Memory Upsizing (N+1): % to 100%

📐

Sizing Source

🔀 Cloud-to-cloud sizing Size a row from its Current Instance Type when it has no CPU Count / Memory (GB). Explicit CPU and memory always take precedence.

Advanced Instance Filtering (Optional)

▼

✨ Current Generation Only Include only latest generation instances (recommended for better performance)

🗄️ Physical-Core Licensing (alternate floor) SQL Server's 4-core licence floor counts physical cores instead of vCPUs — off by default, which counts vCPUs (the licensing basis for a VM licensed directly)

🏷️ Restrict to specific instance family names Choose instance categories (General purpose, Compute optimized, and so on)

🔧 Restrict to specific processor types Choose preferred processor architectures

📋 Restrict to specific instance families Choose main instance families (C, M, R, T, etc.)

❌ Exclude specific instance types Exclude certain categories of instances

🧠 Rule Engine Defaults

Set page-level defaults for all rows. Per-row CSV columns override these. Rules merge with the filters above — conflicts are flagged in red.

Rule descriptions ▸

Rule	Effect
ENV=Production	Excludes burstable (t-family), enforces current-gen, min 4 vCPU for web/DB workloads
ENV=Staging	Excludes burstable, allows smaller sizes than Production
OS=Windows	De-prioritises Graviton/ARM families; prefers Intel or AMD
Workload=Web Server	Sorts m/c families first; Workload=Database sorts r-family first; ML/AI sorts p/g/trn/inf first
Compliance=HIPAA/PCI	Requires Nitro-capable instances; excludes burstable; enforces current-gen
Min Gen=6+	Excludes m5/c5/r5 (Gen 5) and older; keeps m6i/m7i and newer only. Useful as m5 approaches EOL.
Workload=SQL Server	Enforces a 4-vCPU licence floor when it can — SQL Server is licensed per core (minimum four), so a smaller box saves no licence cost. If no eligible candidate is that large, the fallback pick is kept and the rule is reported as not applied.
Workload=ML/AI (GPU)	Requires a GPU/accelerator instance; every other workload excludes accelerators, so a GPU box is not recommended by accident. If the pool has no accelerator to offer, the fallback pick is kept and the rule is reported as not applied.
