Workshop . OpenAI-to-Bedrock Migration

A price table is not a migration assessment. The decision is five-part, and only one of those parts is cost.

Most Bedrock migration pitches arrive as a per-token price chart. The real decision is five-part: workload shape, cost curve, compliance scope, model fit, deployment architecture. Cost is rarely the one that decides it. Two hours on your actual workload. You leave with the evidence to decide, including where the answer is do not migrate yet.

A price table tells you whether the bill works. An assessment tells you whether the migration works.

Most migration pitches lead with per-token pricing. Per-token pricing only matches your bill at very high steady volume. At anything below that, context length, concurrency, and tool-use fanout drive cost more than the per-token rate. And cost is rarely the only axis: in the teams we have assessed, compliance scope or model fit is usually the real driver. The assessment is what covers all three on one page.

The assessment

Five dimensions, in order. Each one constrains the next. Skip the order and the answer changes.

One sequence, not five parallel checks.

Each dimension depends on the one before it. The visual on the left tracks the dimension you're on.

Dimension 01 - Workload shape
Dimension 02 - Cost curve
Dimension 03 - Compliance scope
Dimension 04 - Model fit
Dimension 05 - Deployment architecture
Dimension 01

Workload shape

The part most migration pitches skip.

Call volume per prompt class, context-length distribution, tool-call fanout, model mix. Measured from your OpenAI usage export and your APM traces, not a generic template.

Dimension 02

Cost curve

Per-token is the wrong unit. Workload curve is the right one.

Your current OpenAI spend, Bedrock on-demand per-token, and Bedrock Provisioned Throughput committed capacity modelled over twelve months at your realistic volume and concurrency. Crossover points marked. List price is not in this picture.

Services: Amazon Bedrock . Bedrock Provisioned Throughput
Dimension 03

Compliance scope

Where data sits, who can see it, what you owe the regulator.

SOC2, GDPR, EU AI Act deployer obligations with Aug 2026 enforcement, DORA if BFSI, sector residency rules, model-provenance reporting, audit-trail obligations. Your current OpenAI routing mapped against each, then the Bedrock equivalent.

Services: CloudTrail . KMS . VPC endpoints . PrivateLink
Dimension 04

Model fit

Where each Bedrock model beats, matches, or loses to your current OpenAI point.

Per prompt class, a head-to-head. Claude on Bedrock for reasoning and long context, Amazon Nova for balanced workloads, Titan and Llama on Bedrock where price dominates. Tested on your prompts with Bedrock Evaluations, not a benchmark we chose.

Models: Claude on Bedrock . Amazon Nova . Titan . Llama on Bedrock . Bedrock Evaluations
Dimension 05

Deployment architecture

Staging, observability, fallback, Guardrails. The boring parts that decide whether the migration lands.

The minimum viable production architecture for your workload. VPC endpoints, Provisioned Throughput sizing, CloudTrail audit, Gen AI Observability. The fallback path for a model or region outage. What stays portable, and what is safe to lock in.

What you leave with

Three artifacts. Each one is usable by your team without us, including the one that says do not migrate.

01
Document
The migration assessment
Go, no-go, or partial, tied to your actual workload across all five dimensions.

A written assessment, usually 12-18 pages. The verdict is explicit. Where migration is the wrong answer, that is the answer.

Tied to your actual API call distribution, not a theoretical template.

Verdict per prompt class, not one blanket recommendation

Workloads safe to move first, workloads to hold

Risks called out where migration is the wrong call

Twelve-month sequence, not a theoretical roadmap

02
Spreadsheet
The 12-month TCO model
Your OpenAI spend, Bedrock on-demand, and Provisioned Throughput on one curve. Your actual volume.

A spreadsheet you can re-run with updated inputs. Compliance cost deltas included. Crossover points, sensitivity to growth and concurrency, all modelled.

Yours to keep, whether you proceed with us or not.

Per-model and per-prompt-class cost breakdown

Provisioned Throughput commitment sizing for your curve

Crossover point between on-demand and provisioned

Compliance and audit-trail costs included, not buried

03
List + Architecture
The compliance gap, with remediation
Where the OpenAI stack fails your obligations, and the Bedrock architecture that closes it.

A gap list followed by an architecture diagram. Named AWS services. Named policies. Not legal advice, and your counsel still signs off.

Compliance is the architecture, not the footnote.

Data residency boundary drawn for your workload

EU AI Act deployer obligations mapped to evidence

GDPR, DORA, and sector rule gaps named explicitly

What customers say

When the engagement ends,
what's left in your AWS account is what counts.
