The Technical Vetting Gauntlet: Your Pre-Flight Checklist
Before you sign any contract, put potential providers through a technical gauntlet. Go beyond their marketing materials and demand concrete evidence of their capabilities. This checklist will help you separate the true technical partners from the sales-driven vendors.
-
Demand a Toolchain Deep Dive:
- Assessment & Discovery: Which tools do they use to map application dependencies and server estates? Do they rely on agent-based tools like CloudEndure or agentless options like Azure Migrate? A mature partner will justify their choice based on your specific environment's complexity and security constraints.
- Migration Execution: What is their primary engine for data and VM replication? Are they using native services (e.g., AWS DMS, Azure Database Migration Service) or third-party solutions? Ask for success metrics and potential "gotchas" with their preferred tools.
-
Scrutinize Their Infrastructure as Code (IaC) Maturity:
- Code Quality and Modularity: Don't just accept a "yes" when you ask if they use Terraform or CloudFormation. Request to see sanitized examples of their modules. Look for clean, modular, and well-documented code that follows best practices. This is a direct reflection of their engineering discipline.
- State Management and CI/CD Integration: How do they manage Terraform state files securely and collaboratively? Do they integrate IaC deployments into a proper CI/CD pipeline (e.g., using GitHub Actions, GitLab CI, or Jenkins)? A manual
terraform applyprocess is a significant red flag.
-
Pressure-Test Their Security and Governance Framework:
- Landing Zone Architecture: Ask for a detailed walkthrough of their standard landing zone architecture. How do they structure organizational units or accounts, VPC/VNet networking, and IAM policies? It should be built on a foundation of least-privilege access from day one.
- Compliance Automation: For regulated industries, how do they translate compliance requirements (like HIPAA or PCI-DSS) into automated guardrails and policies? Ask about their experience using tools like AWS Config, Azure Policy, or third-party Cloud Security Posture Management (CSPM) platforms.
-
Define "Done": The Day 2 Handoff and Beyond:
- Observability Stack: A migration is not complete until you have full visibility into the new environment. What is their standard approach to logging, monitoring, and alerting? Do they deploy and configure tools like Prometheus/Grafana, Datadog, or native cloud services like CloudWatch and Azure Monitor as part of the project?
- Knowledge Transfer and Empowerment: The ultimate goal is to enable your team. The handoff should include comprehensive architectural diagrams, runbooks for common operational tasks, and hands-on training sessions. A great partner makes themselves redundant by empowering your engineers.
Ultimately, the best cloud migration service providers act as a temporary extension of your own engineering team. They bring specialized expertise to accelerate your journey and, most importantly, leave you with a secure, automated, and maintainable cloud foundation. Whether you require the immense scale of an enterprise partner or the specialized, code-first approach of on-demand experts, this technical vetting process will ensure your migration is a launchpad for future success, not a source of future technical debt.
