AWS landing zone for multiple teams and workloads | Anexia

For AWS governance, we determine which workloads should be separated from one another and which tasks remain central. Accounts can support security, operational and cost boundaries, but they need a clear model for permissions and shared services. The structure should allow growth without turning every additional application into a manual special case.

For AWS provisioning, identity, logging, network and deployment are aligned with one another. Central controls must not depend on random individual permissions in project accounts. For the AWS landing zone, we also review the path for new accounts and environments: who requests them, which rules apply and who bears the ongoing costs? Protective measures receive understandable evidence and a controlled exception path. A representative service shows whether the foundations are usable in practice. Acceptance covers permitted and denied access as well as the visibility of important operational events. The AWS foundation architecture thus provides a documented framework within which application teams can work independently inside clear boundaries.

Scope of services for the AWS landing zone

The agreed scope of AWS governance can include the following results: account model, identity integration, policies, central logging, network foundations and deployment templates. For each key 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 are replaced with concrete work packages in the offer.

AWS provisioning also includes coordinating the necessary interfaces with your team. We clarify access, contact persons 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 for the AWS landing zone

Account boundaries are chosen according to responsibility and protection requirements. Shared services receive explicitly defined access relationships. For the AWS foundation architecture, we document the relevant assumptions and explain the chosen approach. Key alternatives are considered against the same functional requirements. This makes later adjustments easier when load, data or organisational responsibility change.

A sound decision also takes maintainability and handover into account. In AWS governance, we check 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 recur regularly after the project and which decisions remain with them.

Overly broad organisation-wide permissions can turn a single misconfiguration into a risk for several accounts. We treat this point as a concrete review question in AWS provisioning. A risk is linked to the affected workflow, its possible impact and a suitable measure. Where prerequisites are still missing, the statement explicitly remains open until the necessary investigation has taken place.

We test account creation, permission changes, log access, network isolation and the repetition of a standardised workload deployment. For the AWS landing zone, we record the starting point, the tested configuration and the result. Acceptance refers to the agreed scope. Open restrictions are documented visibly and assigned to a next step with clear ownership. This allows your team to distinguish between proven functionality, a deliberate decision and an assumption that is not yet confirmed.

Project example as an illustrative scenario

The following scenario is an application example and not a customer reference. A company runs development and production applications in AWS accounts that have grown over time. For the AWS landing zone, the first step would be to examine which responsibilities and protection boundaries the new structure should reflect. An account separation would have to match real responsibilities and must not interrupt existing data flows unnoticed.

For the AWS foundation architecture, a new workload would go through the planned onboarding process. Identity access, logging, network connections and cost tagging would be checked as one connected workflow. The pilot would also include a denied impermissible action and the revocation of access. Shared services would need to remain reachable without every application team taking over their entire administration. For existing workloads, dependencies and transition steps would be described separately. Otherwise a new target architecture might be neatly documented but impossible to operate with the actual application.

Acceptance of the AWS governance work would cover a traceably set up workload and working operational paths. The planned results would be an account and role model, deployment templates and clear rules for exceptions. The organisation could then judge which tasks are provided centrally and which remain with the product team. Further accounts would be onboarded according to this allocation. Binding security and cost decisions would stay linked to responsible people instead of being hidden solely in technical templates.

Our experience and our engineering approach

We combine custom software development with the technical tasks of introduction and further development. For the AWS foundation architecture, we bring the perspectives of application, integration and operations together in a shared workflow. The functional requirements remain connected to the technical decisions. You work with a defined scope of services and traceable results.

Our experience should be concretely verifiable for your project. That is why, in a technical exchange, we explain how we investigate the relevant risks, which work results are planned and how your team can assess them. For AWS governance, we align the roles involved with actual needs. Available references are placed in the context of the respective project and company; confidential customer details are not used as general marketing claims.

Effort for AWS governance

The number of existing accounts, the network topology, identity integration and required exceptions determine the effort. We therefore calculate the AWS landing zone on the basis of a clearly defined scope and explicitly stated prerequisites. An initial analysis step can make sense if key technical information is still missing. After that, work packages and acceptance criteria can be agreed more reliably.

The AWS foundation architecture 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 covered by separate agreements. This makes it clear which services are provided once and which tasks recur regularly after introduction.

Scope limits of the AWS landing zone

The offer covers the foundation of the cloud organisation; optimising the costs of individual applications is addressed separately in more depth. For AWS provisioning, we record this limit in the offer itself. Any additional services required are included with their functional justification and are not silently assumed. Your team can therefore plan suitable internal skills and divide the overall work sensibly between the parties involved.
