Cloud Governance Accelerator

Governance is the foundation everything else depends on.

Many AWS environments grow faster than their governance. One account becomes ten, ten become thirty - without consistent policies, without central visibility, without audit evidence. The Cloud Governance Accelerator builds that foundation.

We build an operational, auditable landing zone based on AWS Control Tower and the Tallence Baseline - a collection of Infrastructure-as-Code modules that technically enforce regulatory requirements instead of merely documenting them.

Cloud Governance Accelerator

Compliance-as-Code: regulatory requirements translated into code that enforces them automatically.

The Cloud Governance Accelerator works for teams starting fresh who want the right structure from day one, and for teams with existing AWS accounts that need to be brought into order without disrupting ongoing operations.

The outcome is a working governance engine that prevents regulatory drift and gives your team the space to focus on products.

Service scope

Three phases. One result: a working landing zone.

In this phase, the fundamental design decisions are made that serve as the blueprint for the entire AWS environment. Together with your team, we develop the OU structure, network design, and identity concept.

Deliverables in Phase 1

  • OU structure design based on your business logic (Security, Shared Services, Workloads, Sandbox)
  • Network design with IPAM, Transit Gateway architecture, and hybrid connectivity
  • Identity design: integration of your identity provider (Azure AD, Okta) with AWS IAM Identity Center
  • Definition of role model, permission sets, and governance processes
  • Compliance mapping: assignment of your regulatory requirements to technical controls

Outcome of this phase

Complete architecture documentation (HLD + LLD) as blueprint for implementation

Brownfield vs. Greenfield

Existing environments get structure, not a rebuild.

Many teams have AWS accounts that grew organically over years. The Cloud Governance Accelerator brings structure to those environments without discarding what works. Your existing workloads stay running while governance is built around them.

Typical starting situation
IAM user with administrator rights used for daily tasks, MFA missing
Sprawl in a single account with no cost transparency
No log aggregation, no centralized security monitoring
Inconsistent IAM policies, outdated access rights without review
No compliance evidence for GDPR, ISO 27001, or BSI C5
After the engagement
Management account isolated, root user locked, MFA enforced via SCP
Multi-account structure with OU hierarchy and centralized cost management
Centralized CloudTrail, GuardDuty, and Security Hub across all accounts
Permission sets via IAM Identity Center, automated access review
Automated compliance evidence via AWS Config Conformance Packs

What comes next?

The foundation is built. Now it needs to be operated.

A landing zone is not a one-time project - it requires continuous attention. AWS releases Control Tower updates, GuardDuty fires alerts, IAM roles accumulate, costs drift. Tallence Cloud Foundation takes that operational responsibility off your plate so your team can focus on shipping.
