AWS Architecture & Migrations

We design the AWS architecture and run the migration of applications into the new environment. Accounts, identity, network, security, governance and cost are settled before the migration starts.

A well-defined architecture cuts rework, makes the platform easier to run, and stops every new application from needing its own bespoke solution.

Outcome

An AWS architecture that is organized, documented and ready to take on new applications without adding unnecessary complexity.

What we do

  • Multi-account structure and governance

    We organize accounts and organizational units, centralize identity and access, and define the controls the environment needs, using AWS Organizations, Control Tower, SCPs, RCPs, IAM Identity Center and AWS Config.

  • Application migration and modernization

    We assess each application and choose the migration strategy that fits it: rehost, relocate, replatform, refactor, repurchase, retain or retire. Where it applies, we modernize onto Amazon ECS, Amazon EKS, AWS Lambda or Amazon RDS.

  • Infrastructure as code

    We implement the architecture in modular Terraform, with policy as code, environment promotion and drift detection.

  • Security and compliance by design

    We account for PCI-DSS, ISO 27001 and LGPD in the architecture, with account segregation, access controls, audit trails and the evidence an audit will ask for.

  • Hybrid and multi-cloud scenarios

    We integrate AWS with Azure and GCP when a company already runs environments on more than one provider, covering connectivity, identity, security and operations.

How we work

  1. We start from what is already there

    We map accounts, identities, network, cost and dependencies before defining the target architecture.

  2. We define the target architecture

    Account structure, policies, identity, network, security and deployment standards are settled before the migration.

  3. We implement in code

    The architecture is implemented in Terraform, with environment promotion and drift detection.

  4. We migrate in waves

    Applications are grouped into migration waves, each with acceptance criteria, named owners and a rollback plan.

  5. We leave the team ready to operate

    The in-house team can open a new account inside the standard, change an access policy and promote an environment through its own pipeline, backed by documentation and joint work through the transition.

AWS services and tools involved

  • AWS Organizations
  • AWS Control Tower
  • IAM Identity Center
  • AWS Config
  • Amazon ECS
  • Amazon EKS
  • AWS Lambda
  • Amazon RDS

Where we usually come in

  • AWS environments that need structure

    Companies that grew on AWS without a consistent architecture for accounts, identity, network and governance, and need to organize the platform before growing further.

  • Migration or modernization projects

    Companies that need to migrate applications to AWS, modernize existing workloads or define a migration strategy without interrupting current operations.

  • Regulated or complex environments

    Organizations in sectors such as financial services, energy and healthcare that need to combine AWS architecture, security, governance and compliance requirements.
