Infrastructure as Code: Terraform & More
Make infrastructure changes traceable and repeatable.
Manually grown cloud environments can often only be changed with a lot of experience. Infrastructure as Code makes the desired state describable and changes verifiable. We work with you to develop reusable building blocks and a regulated process from planned change to deployment, including secure state management and the transfer of existing resources.
Service modules
From a single script to a viable change process.
Tools and ownership boundaries
We evaluate Terraform, OpenTofu, vendor-specific tools, and supplemental configuration procedures based on your environment. Responsibilities for resources, interfaces, and licenses are clarified so that multiple tools don't manage the same resources inconsistently.
A well-founded choice of tools and a clear allocation of the managed infrastructure.
Modules and versioning
We cut reusable modules along sensible responsibility and lifecycle boundaries. Inputs, outputs, standards and version changes are documented; examples help teams to use the building blocks correctly and to develop them further in a targeted manner.
A usable module catalog with defined interfaces, examples, and version rules.
State, access and secrets
We plan for protected storage, access, locking mechanisms, and infrastructure state recovery. State and plan files can contain sensitive values; their handling is regulated as well as the identities of executing pipelines.
A validated approach to state data, permissions, and how to handle secrets.
Change review and approval
Formatting, validation, testing, and policy checks are incorporated into the change process. Planned changes are assessed before application; shares take into account the environment, impact, and access of the executing identity.
A comprehensible process from the change request to the checked apply.
Adopting existing resources and detecting drift
We record existing resources and prepare their controlled takeover. Deviations between configuration and reality are made visible and evaluated before corrections are made. Critical replacements or deletions require special scrutiny.
A coordinated takeover plan and a regulated handling of configuration deviations.
Operations and maintenance
We structure documentation, troubleshooting and maintenance of the automation. Provider and module updates are planned, recovery paths are tested and knowledge is built up in the team so that the solution can be maintained after implementation.
Operating instructions and an agreed maintenance process with clear responsible persons.
Application examples
Infrastructure as Code: Terraform & More Use Cases
These exemplary starting points show possible projects. Together, we narrow down what makes sense for your organization.
Inherit manually created cloud resources
In the future, a productive environment will be managed via reviewed code. We record resources and dependencies, test the adoption on a limited area and check every planned change before application.
Standardize different team modules
Several teams maintain similar network or platform building blocks. We develop common interfaces and standards, introduce versioning and plan a gradual transition without uncontrolled changes to existing environments.
Deploy environments consistently
Development and production deviate from each other unnoticed. We separate joint configuration from deliberate differences and test a repeatable deployment path with protected status data and appropriate releases.
Collaboration
Start small and adopt changes in a controlled manner.
Review existing resources and change processes
We collect resources, existing repositories, permissions, and manual intervention. A demarcated infrastructure area is selected as a pilot.
Design modules and state management
Resource boundaries, module structure, state storage, and pipeline identities are aligned. We define the necessary checks and how to handle high-impact changes.
Automate and test the pilot
Configuration and test procedure are implemented. Existing resources are taken over in a controlled manner or new test resources are made available; plan results are evaluated together.
Prepare handover and expansion
The team carries out typical changes themselves. We document error handling, maintenance and recovery and prioritize the next areas that can be conveniently automated.
Your result
What you can use in concrete terms
- Repository and module structure with documented interfaces and version rules.
- Protected state management and regulated execution permissions.
- Review and release process for planned infrastructure changes.
- Adoption plan for inventory resources, as well as guidance for maintenance and drift handling.
SYNEDAT PLATFORM
Platform experience for your project
We use these selected tools in SYNEDAT PLATFORM or its delivery processes. We adapt suitable practices to your project and align their integration with your existing systems.
From source code to verified artifacts
Azure DevOps · GitLab · Jenkins · Harbor · Nexus
Version control, build processes and artifact repositories make software versions traceable. Our platform approach connects these activities with defined checks and approvals. For your project, we select tools that fit your teams and existing processes.
A clear delivery process and traceable software versions.
Deployment and platform automation
Kubernetes · Azure Kubernetes Service · Helm · Argo CD · Terraform
Versioned configuration and declarative deployment connect infrastructure and applications. GitOps makes proposed changes reviewable and the desired state explicit. Operational transitions and recovery procedures are still planned for the specific application.
Repeatable changes and clearer responsibility boundaries.
Quality and the software supply chain
SonarQube · Trivy · Dependency-Track · DefectDojo · Renovate · Syft · Cosign
Code quality, vulnerabilities, dependencies and artifact provenance require different checks. Findings need to be linked to the product and delivered version, with a defined process for resolving them. Automated checks complement reviews and informed decisions.
Security and quality information that teams can act on.
Frequently Asked Questions
Do existing resources need to be rebuilt?
Not necessarily. Depending on the tool and resource type, it is possible to transfer it to the administration. In particular, we check whether the configuration and the real state match. An import alone does not confirm that later changes can be applied without undesirable effects.
Does Terraform’s sensitive flag fully protect sensitive values?
The sensitive flag can hide values in output, but it does not secure state and plan files. Depending on the configuration and provider, those files can still contain secrets. We address storage, access, encryption and supported ways to avoid persisting sensitive values.
Can every infrastructure change simply be rolled back?
No. A previous code state does not automatically restore deleted data or replaced resources. We distinguish between reversible configuration changes and interventions that impact data or availability, and plan separate backup, release, and restore procedures for them.
How can several teams work reliably on infrastructure?
Shared module conventions, traceable changes and reviewable approvals provide a common foundation. We clarify responsibilities, access rights and the handling of shared state. Automated checks and clear documentation support collaboration within the agreed tool environment.
What happens to changes made outside the code?
We plan how differences between the declared and actual state are detected and assessed. Responsible teams decide whether to adopt, correct or document a change as an exception. Emergency changes receive a defined route back into the traceable configuration.
