Migrating to the cloud is no longer an option but a strategic decision that directly impacts your business’s efficiency, security, and competitiveness.
However, a poorly planned migration can result in unexpected costs, performance loss, or availability issues.
In this CloudAPPi whitepaper, we show you how to design a solid migration strategy, whether from an on-premise environment or between clouds, and how to leverage DevOps, IaC, and FinOps practices to ensure an agile, secure, and scalable process.
You will learn how to evaluate which migration model best fits your needs (lift and shift, replatforming, refactoring, or multicloud) and how to structure your technical roadmap to achieve a successful cloud adoption.
Before migrating, it is essential to define a target architecture that includes networks, storage, compute, and service dependencies. DevOps teams should create pre- and post-migration architecture diagrams, identify critical components, and determine whether each application will be migrated through lift and shift, replatforming, or refactoring.
In addition, it is recommended to use IaC (Infrastructure as Code) with Terraform or AWS CloudFormation to version and validate the infrastructure before deploying it in the production environment.
Security must be integrated from the pipeline (DevSecOps). This includes vulnerability analysis in the code (SAST/DAST), dependency review (Trivy, Snyk, Dependabot), and configuration validation through Policy as Code (OPA, Conftest).
At the network level, make sure to apply the principle of least privilege with IAM, segment environments with VPCs and private subnets, and enable continuous audits with tools such as AWS Config, Azure Policy, or GCP Security Command Center.
The key is to migrate in phases and use safe deployment strategies such as blue/green or canary releases. This allows traffic to be progressively redirected to the new infrastructure and enables immediate rollbacks if something fails.
It is also recommended to implement temporary database replicas through synchronization or real-time replication (for example, AWS DMS or Azure Database Migration Service) to minimize downtime.
Modern migrations rely on a combination of tools:
IaC: Terraform, Ansible, or Pulumi to define declarative infrastructures.
CI/CD: Jenkins, GitLab CI, GitHub Actions, or ArgoCD to automate deployments.
Observability: Prometheus, Grafana, Loki, and OpenTelemetry to monitor performance and traceability.
Multicloud management: tools like Crossplane or Spacelift allow unified operations in hybrid or multi-cloud environments.
The choice will depend on the provider and the desired level of automation.
