AWS cost optimisation for existing workloads
Different pricing models, reservations and data transfers make it hard to tell which measures actually make economic sense. With AWS cost optimisation, we offer you optimisation geared to real workloads, with a documented impact on costs and operations.
Examining AWS spending by consumption, commitment and architecture
Our offering is aimed at IT teams with several AWS services and a specific need for optimisation. For companies in Germany, Austria and Switzerland, we plan the AWS cost analysis based on the existing systems and the collaboration required.
For AWS FinOps, we first separate the causes of high spending. Unused resources, unsuitable sizing, data traffic and pricing conditions require different measures. A change should clearly match the respective cause. Technical usage values are therefore linked to the relevant cost items and considered over a representative period.
In AWS cost management, longer-term pricing commitments are only assessed together with a suitable consumption forecast. A commitment can improve the unit price but at the same time limit flexibility. For AWS cost optimisation, we first check whether the expected baseline demand will remain after planned technical changes. Transfer paths and storage classes are also assessed based on actual access. A lower storage fee can be offset by retrieval costs or recovery effort. Measures are agreed with the responsible teams and checked under comparable conditions. In this way, the AWS cost analysis delivers well-founded optimisation steps whose effect is not derived solely from an advertised discount or a short-term utilisation measurement.
Scope of services for AWS cost optimisation
The agreed scope for AWS FinOps can include the following results: cost breakdown, usage analysis, sizing recommendations, commitment assessment and implementation plan. For each significant result, we define what it is for, who reviews it and in what form it is handed over. This allows development, operations and procurement to assess the same service. Vague umbrella terms in the proposal are replaced by concrete work packages.
AWS cost management also includes coordinating the necessary interfaces with your team. We clarify access, contacts and available testing options before the relevant implementation steps. Changes to the scope are described together with their impact on effort and sequence. This gives you a clear overview of delivered results, outstanding prerequisites and additional requests.
The key technical decision in AWS cost optimisation
Discount commitments are only assessed after a reliable baseline demand has been verified. With the wrong commitment, a cheaper unit can still lead to higher total costs. For the AWS cost analysis, we document the relevant assumptions and explain the reasons for the chosen option. Significant alternatives are considered against the same business requirements. This makes later adjustments easier when load, data volume or organisational responsibility change.
A sound decision also takes maintainability and handover into account. In AWS FinOps, we examine which skills are available internally and what additional support is needed. This connects technical possibilities with a realistic operating model. The client can see which tasks will arise regularly after the project and which decisions remain with them.
What supports good decisions.

Decisions need technical understanding.
Determining baseline demand before pricing commitments
Long-term pricing commitments should be based on sufficiently reliable demand. Before making such a decision, we look at unused resources, suitable sizing and planned architecture changes. Otherwise, a commitment can lock in spending that could have been avoided technically.
- Creating a reliable cost base
- Analysing consumption and price separately
- Keeping availability as a constraint
- Limiting automatic measures
- Safeguard forecasts with scenarios
- Optimisation as a verifiable change
Risks and acceptance in the AWS cost analysis
Downsizing resources can affect load peaks or necessary recovery reserves. In AWS cost management, we treat this point as a concrete review question. A risk is linked to the affected process, its possible impact and a suitable measure. Where prerequisites are still missing, the statement remains explicitly open until the necessary investigation has taken place.
We compare costs and performance values before and after a controlled change under comparable usage conditions. For AWS cost optimisation, we record the initial situation, the tested configuration and the result. Acceptance refers to the agreed scope. Open limitations are documented visibly and assigned to an owned next step. This allows your team to distinguish between a proven function, a conscious decision and an assumption that has not yet been confirmed.
Project example as an illustrative scenario
The following scenario is an application example and not a customer reference. A SaaS operator uses several AWS services with strongly fluctuating utilisation. In AWS cost optimisation, the first step would be to examine which spending results from permanent baseline demand and which from load peaks. Unused resources, oversized capacity and unfavourable data paths would be separate causes with different measures.
For the AWS cost analysis, a selected workload would be examined under representative loads. A smaller resource would have to be sufficient not only on average but also during peaks and error conditions. Technical changes would be tested with a fallback option. Only on the basis of the reliable demand remaining afterwards would longer-term pricing commitments be assessed. The comparison would also have to take into account data transfer, storage operations and additional operational work. Otherwise, a cheap individual item could come at the price of higher costs elsewhere.
Acceptance of AWS FinOps would document cost development and service quality together. The planned results would be well-founded adjustments, traceable usage assumptions and a suitable measurement period for the effect. General discount figures would not replace an assessment of the actual terms. The client could see which reduction was achieved technically, which share is due to changed usage and which obligations arise from a contract decision. Growth and new features would be a reason to review these assumptions again.
Our experience and our engineering approach
We combine custom software development with the technical tasks of introduction and further development. For the AWS cost analysis, we bring the perspectives of application, integration and operations together in a shared workflow. Business requirements remain connected to the technical decisions. You work with a defined scope of services and traceable results.
Our experience should become concretely verifiable for your project. That is why, in the technical exchange, we explain how we examine the relevant risks, which work results are planned and how your team can assess them. For AWS FinOps, we align the roles involved with the actual need. Available references are presented with their respective project and company context; confidential customer details are not used as general promotional claims.
Effort for AWS FinOps
The variety of services, volatility of usage, existing commitments and the quality of allocation determine the effort. We therefore calculate AWS cost optimisation on the basis of a defined scope and explicitly stated prerequisites. An initial analysis step can make sense if essential technical information is still missing. Work packages and acceptance criteria can then be agreed on a more reliable basis.
The AWS cost analysis can be organised as a limited project, as a joint implementation with your team or with subsequent support. Rights of use, access, documentation and responsibilities are clarified in the contract. Ongoing operating hours, response times and external consumption costs are subject to separate agreements. This keeps it clear which services are provided once and which tasks arise regularly after the rollout.
Boundaries of AWS cost optimisation
Current rates and contract terms are reviewed case by case; general savings percentages are not a basis for a proposal. For AWS cost management, we already set out this boundary in the proposal. Required additional services are included together with their business rationale and are not silently assumed. Your team can therefore plan suitable internal skills and divide the overall work sensibly between those involved.
