Cloud Platform Planning Tools
Turn rough architecture assumptions into numbers you can challenge in a design review. The calculators expose every input and formula, keep entered values in your browser, and produce a plain-language summary you can copy into a planning document.
Private by design: calculator values are processed in your browser by the site’s own JavaScript. The tools do not submit those values to Velynoriva.
Traffic, storage, and headroom
Multi-Tenant Capacity Planner
Estimate steady traffic, peak load, a provisioned throughput target, monthly request volume, payload transfer, and twelve-month storage. Use the results to define load-test scenarios; do not treat them as an instance-sizing recommendation.

Suggested test envelope
Formula notes
steady RPS = active tenants × requests per tenant per minute ÷ 60. The provisioned target multiplies steady RPS by the peak factor and then adds headroom. The monthly volume assumes that the entered average continues for 30 days. Transfer includes response payload only and excludes protocol overhead, retries, uploads, cache hits, compression, and replication.
Shared tables, schemas, or databases
Tenant Isolation Decision Planner
Compare three common data-isolation models against workload skew, recovery boundaries, customization, compliance pressure, team capacity, and tenant count. The result is a review starting point with visible scoring, not a compliance determination.

Design-review questions
How scoring works
Each answer adds transparent fit points to shared-table, schema-per-tenant, and database-per-tenant models. Hard isolation and tenant-level recovery favor dedicated databases. High tenant count and lean operations favor shared infrastructure. Close scores indicate that a tiered or hybrid model deserves consideration.
Measured allocation and gross margin
Tenant Unit Economics Calculator
Compare equal-share infrastructure allocation with usage-weighted allocation for one tenant. Add dedicated support or infrastructure cost to see estimated tenant COGS, gross margin, and the price required to reach a target margin.

Interpretation
Formula notes
Usage-weighted shared cost is shared platform cost × tenant usage ÷ total usage. Estimated tenant COGS adds tenant-specific costs. Gross margin is (revenue − COGS) ÷ revenue. This planning model excludes costs that you do not enter, such as support labor, payment fees, observability, credits, taxes, and unallocated overhead.
Use estimates as questions, not proof
These tools make assumptions explicit so a team can replace them with measurements. Before making a production commitment, compare calculator output with load tests, billing exports, database statistics, queue depth, support cost, contractual isolation requirements, and recovery exercises. A precise result based on a weak input is still a weak result.

Common questions
Do these tools upload my architecture or financial data?
No. The calculator code reads the form values and computes results in your browser. It does not submit form values to a Velynoriva endpoint. Normal page requests, analytics, and advertising technologies may still process general visit information as described in the Privacy Policy.
Are the recommendations vendor-specific?
No. The models use workload and cost relationships rather than instance names. You can apply measured capacity or cost data from any hosting provider or self-managed environment.
Can the isolation result establish compliance?
No. It is an architecture-screening aid. A contractual clause, regulator, auditor, or threat model may require controls that outweigh the score. Record those requirements before choosing a tenancy model.
How should I report a formula issue?
Send the input values, the result you expected, and the formula you believe should apply through the contact page. Do not include secrets, customer names, or confidential account data.
