Cloud architecture · Modernization

What to modernize first, and why that order

Assessments, reference architectures and enablement for teams moving to AWS or cleaning up what they already run there. Empowerment over outsourcing: your team makes the decisions and can explain them afterwards.

  • €2,000 per workshop
  • €1,000 per written result
  • AWS, hybrid and on-premises
  • Vienna or remote
The usual situation

The question is rarely whether to modernize

It is which of the forty systems earns it first, and what happens to the rest. Teams that skip that question end up with a lift-and-shift bill and the same operational problems, now hourly billed.

I work through it with your team: what runs today, what it costs, which constraints are real (data residency, licences, compliance, skills), and which workloads change the numbers when they move. The output is an order, not a wish list[1].

Where AI is part of the plan, the same layer logic applies as in my lecture: how much of the stack you operate yourself is a constraint decision, not a taste decision[3].

The goal is that your team can explain every decision six months later, without me in the room.

What you get

Written results you can act on

The workshop is €2,000, each written result €1,000. Most teams take two.

1

Modernization assessmentIncluded

Every candidate workload with its current cost, its constraints and the effort to move or rebuild, in one comparable table.

2

Reference architectureIncluded

The target picture for the first wave: accounts, network, identity, data and operations, drawn so both sides can read it[1].

3

Cost modelOptional

What the target costs per month at your volume, with the assumptions written next to the number[4].

4

Funding caseOptional

Whether AWS migration or modernization funding applies, and what an application needs[2].

Hybrid, when it is the answer

Not everything has to move

Sometimes the data cannot leave the building, sometimes the licence makes the move pointless. Then the question becomes where the boundary runs and what crosses it.

Five steps for drawing a hybrid architecture: boundaries, data classes, flows, controls, operations.
How we draw the boundary in the session: what stays, what moves, and which facts cross.Source: Linda Mohamed, lecture “Von Managed zu Hybrid: KI-Architekturen”, Hochschule Burgenland, 2026

Who operates what

Modernization is a responsibility decision

Before any service name comes the question of how much of the stack you want to run, and what the provider owes you once you stop.

AWS services

The AWS services behind this work.

The building blocks that show up in most modernization plans, with a plain note on what each does and a link to the AWS documentation.

AWS Organizations

Groups AWS accounts, applies guardrail policies and consolidates billing.

AWS Identity and Access Management (IAM)

Who and what may call which service. For agents: one narrow role per agent.

AWS Well-Architected Framework

AWS guidance for reviewing workloads on security, reliability, cost, performance, operations and sustainability.

Red Hat OpenShift Service on AWS (ROSA)

Managed OpenShift clusters in your AWS account. The base for running OpenShift AI next to other AWS services.

Amazon FSx for NetApp ONTAP

Managed NetApp file storage on AWS. With S3 access points it bridges on-premises file shares and cloud AI services.

AWS Outposts

AWS-managed racks in your own data centre for workloads that must stay on site.

Amazon CloudWatch

Logs, metrics and alarms. For AI systems: latency, errors and cost per call.

AWS Pricing Calculator

Builds a cost estimate per service before anything is deployed.

Funding

Check AWS funding before you pay.

Many AI proofs of concept and cloud migrations qualify for AWS funding: credits for the AWS usage and, in some partner programmes, funds for the delivery work. What applies depends on the project, the programme and the AWS account team. I check it in the Idea Call, and the workshop results are written so they can go straight into an application.

Proof of concept

Up to €10,000

For a prototype on AWS with a clear path to production.

Migration

Up to €400,000

For larger cloud moves, planned in phases.

Questions

What people ask before booking.

Do you do the migration yourselves?

I do the architecture, the assessment and the enablement, and I work with your team or your partner for the execution. If you need a delivery partner, I say so early.

What does the review cost?

€2,000 for the workshop plus €1,000 per written result. The standard package with assessment and reference architecture is €4,000 net.

We already run on AWS but it is a mess. Does this fit?

Yes. Then the assessment looks at accounts, identity, cost and operations rather than at moving anything.

Can AWS pay for part of it?

Migration and modernization programmes have funding attached in some cases. What applies depends on the project and the AWS account team; I check it before you commit.

Do you cover hybrid and on-premises?

Yes. Red Hat OpenShift on AWS, FSx for NetApp ONTAP and Outposts are part of the toolkit when the data cannot move.
