Cloud architecture & landing zones with OTOKO®

Cloud growth needs clear boundaries.

New cloud projects should not have to solve fundamental questions about accounts, access and networks from scratch every time. A landing zone provides a shared technical foundation for this. OTOKO® translates your organizational structure and requirements into a usable cloud architecture and sets up the provisioning path for further teams and applications.

Your brief for OTOKO®

Shared rules for your next cloud expansion.

Different account structures and manual approvals make a growing cloud footprint hard to oversee. At the same time, not every project needs the same freedoms. Together, we distinguish binding foundations from justified exceptions and examine how existing applications can be incorporated into the target state.

What you engage us for

Architecture concept and technical implementation belong together here. In addition to the configured foundation, your team receives versioned configurations, documented roles and a tested change path. This makes it possible to trace how new environments are created and who approves extensions.

The services in detail

Scope

Create the foundation for further cloud projects.

Organization, permissions and network form the foundation. Technical rules and versioned provisioning make sure your team can actually apply and extend this architecture for new projects.

Structure teams and environments

Development, test and production need a separation that fits your organization. Together, we organize environments, responsibilities and cost centers, and put this structure in place. The onboarding path for new projects is described, so the rules remain applicable after the initial setup too.

What your team keeps working with

An organizational structure with responsibilities and a documented onboarding process.

Technical implementation

Accounts, projects & responsibilities

Subscriptions, accounts or projects are structured according to organization and security boundaries. Every environment needs technical owners and cost accountability. We also plan the life cycle from the request for an environment to its later decommissioning.

Set up access and network connections

Administrative permissions and application connections are derived from specific tasks. The configuration reflects these roles and data paths, including the connection of on-premises services. Access tests show whether the intended participants can actually carry out their work.

What your team keeps working with

A role and network model, including administrative procedures.

Technical implementation

IAM, RBAC & network foundation

Identities, roles and administrative access are coordinated with segmentation and name resolution. Hybrid connections receive defined data paths. Permissions are scoped to tasks; exceptions and emergency access must remain traceable.

Build shared rules into the platform

Requirements become effective when they are reflected in controls, logs and tagging. We set up the agreed rules technically and document their scope. For necessary exceptions, a deliberate decision path is defined.

What your team keeps working with

A coordinated rule catalog with implemented controls and documented exceptions.

Technical implementation

Policies, logging & cost tagging

Technical guardrails implement agreed rules for resources and configuration. Azure Policy is one platform-specific example; other providers require suitable mechanisms. Central logs, tags and budgets support traceability and allocation.

Make provisioning of new environments repeatable

Versioned infrastructure configuration makes changes traceable and provisioning repeatable. Using a planned extension, we test the process from proposal through review to implementation. Your team takes over the configuration together with the documentation of this procedure.

What your team keeps working with

A usable repository with a provisioning path and handover documentation.

Technical implementation

Terraform, Bicep & controlled changes

Infrastructure as code describes the platform in versioned form. Reviews, provisioning and state management are planned as an operational process. We hand over configuration and documentation so that your team can build new environments in a controlled way and track changes.

Planning & implementation in detail

A landing zone must prove itself on the next project.

The shared cloud foundation should not just describe rules, it should make them usable in practice. What matters is whether a team can use it to onboard a new application, review a change and take on responsibility. We align the architecture and handover with precisely this.

Translate the organization into technical boundaries

Accounts, environments and administrative rights must match the actual organization. A separation by business unit is not always the same as a separation by application or operational responsibility. Together, we therefore examine who requests resources, who supports them and to whom costs should be allocated. Existing environments are taken into account as well. The target state then describes the intended boundaries and the reasons for them, so that later changes are not made solely on the basis of names that emerged by chance or of historical responsibilities.

Development, test and production each receive the separation they require. It is also defined how shared services are used and which exceptions can be permitted. The implementation is not meant to prevent every special case, but to allow a clear way of handling it. A defined exception process names the decision and the responsibility for it. This keeps the architecture explainable even when individual applications have special requirements or an existing workload can initially only be incorporated into the shared structure step by step.

Connect rules with provisioning and change procedures

A documented policy does not change a single resource on its own. For the agreed requirements, we therefore check which ones can be technically implemented and which still require an organizational decision. This includes roles, network access, logging and cost tagging. The configuration should make it clear which rules are binding and where approvals are required. At the same time, the path for changes is described, so that a later adjustment does not have to happen outside the shared foundation.

Versioned configuration makes it possible to review changes and record the intended state in a traceable way. Within the agreed scope, this is used to build a repeatable provisioning path. It is tested with a specific environment, including the required checks and access. Your team receives the configuration together with the procedures for using it. This turns a platform that was set up once into a foundation that further projects can build on, and whose maintenance does not rest solely with the original project participants.

Use the first application as acceptance of the foundation

Whether the landing zone works in practice becomes clear with a real application. Your team must receive the intended resources, reach the required systems and be able to carry out its work with the rights assigned to it. This first run makes missing information and unnecessary hurdles visible. Together, we then distinguish between a necessary requirement and a process that should be simplified. These observations feed into the configuration and documentation before further teams are onboarded.

The handover includes responsibility for platform maintenance, onboarding new projects and approving changes. Open points are also documented together with their consequences. A landing zone is not a final security or compliance confirmation for every application later operated on it. The configuration and use of each application must still be considered separately. The foundation that has been created supports these tasks by providing shared procedures and making the responsibility for extensions and deviations visible.

How we work together

You know your business.
We handle the agreed cloud work.

You do not have to organize every technical step yourself. We record tasks and decisions and involve your team wherever its knowledge or approval is needed.

Translate the organization into architecture

Team structure, environments and requirements are mapped to a shared target state. Existing resources and necessary exceptions are taken into account.

Your contribution: Name responsibilities, binding requirements and the first projects to onboard.

Test the foundation with one project

Accounts, permissions and network are set up. A specific project tests whether the planned provisioning path is practical.

Your contribution: Have the pilot team review access and workflows, and give feedback on obstacles.

Make extensions governable

Versioned configuration and the change procedure are handed over. The documentation also describes how new projects and exceptions are handled.

Your contribution: Define who maintains the platform rules and approves later changes.

Example project scenario

Several teams start at the same time

This is what a joint project could look like. The specific scope results from your current situation.

The current situation
Each department builds its own cloud resources. Names, permissions and network rules differ.
Our approach
We develop a common standard and test onboarding one team before further environments follow.
The target state
New projects start with defined access, cost centers and operating rules, while exceptions are decided deliberately.

What you get

For the first consultation, these documents do not yet need to be complete. Together we clarify what is available and which information the assessment should add.

Helpful for getting started

Team structure, platform accounts and identity management
Network plan and security requirements
Existing provisioning and approval processes

How this becomes a specific quote

The scope of services, the involvement of your team, required access, acceptance criteria and the handover are recorded in the quote. Provider fees, project services and ongoing operations are clearly separated.

Discuss your assessment

Before you start

Your questions.
Clear answers.

What do we get with Cloud architecture & landing zones?

Landing zone as Terraform code with pipeline. Architecture and policy documentation. Permission and network concept with evidence. We agree on scope and acceptance criteria at the outset.

Can we start with an existing environment?

Yes. We review your existing applications, interfaces and operational processes and scope the required changes together. A complete rebuild is not automatically necessary.

How are effort and responsibility defined?

After the current-state review, we align work packages, responsibilities, acceptance criteria and the handover. This results in a quote for the specific project scope.

Is a landing zone a single product?

No. It refers to a coordinated platform foundation made up of architecture, configuration and operating rules. The implementation differs between Microsoft Azure, Telekom Cloud and AWS.

Can we integrate existing resources?

Yes. We review dependencies and deviations from the target state. The adjustment is carried out in a controlled way; not every resource has to be rebuilt from scratch.

Cloud architecture & landing zones with OTOKO®

What holds your teams back when they start in the cloud?

Using examples from your day-to-day project work, we identify which foundations are missing: access, network, account structure or provisioning. This defines the scope for your landing zone and for onboarding the first application.
