The challenge

Why businesses migrate to the cloud

On-premise infrastructures and unoptimized cloud setups become a brake on growth. The warning signs are clear:

  1. 01 Aging on-premise infrastructure: end-of-life servers, critical updates postponed
  2. 02 Uncontrolled cloud costs: bills rising 30% per year with no visibility or governance
  3. 03 Zero observability: no metrics, no centralized logs, blind debugging
  4. 04 Manual deployments: risky production releases, impossible rollbacks, no CI/CD
  5. 05 Security vulnerabilities: no WAF, no systematic encryption, overly permissive IAM
  6. 06 No autoscaling: permanent overprovisioning or crashes during traffic spikes
  7. 07 Single point of failure: mono-zone architecture, no failover, no disaster recovery
  8. 08 Degraded time-to-market: 2 weeks to provision a test environment

Our methodology

How we deliver

Architects with twenty years behind them, and a delivery process instrumented by AI: scoping, code review, quality and security tooled at every phase. Each step produces concrete deliverables, and we stay through the run.

01
2 to 3 weeks

Infrastructure Audit & Diagnosis

Map the existing infrastructure, identify workloads, assess cloud maturity, and define objectives. We don't migrate blindly - we start from your infrastructure reality.
Deliverables
  • Complete workload inventory (servers, databases, services, dependencies)
  • Network mapping and inter-system data flows
  • Current cost analysis (infra, licenses, operations, on-call)
  • Organization cloud maturity assessment
  • Quick wins and major risks identification
  • Existing security and compliance assessment
  • Dev, Ops, and business team interviews
  • Diagnostic report with prioritized recommendations
02
3 to 4 weeks

Target Cloud Architecture

Design the target cloud architecture based on your business, technical, and regulatory constraints. Choose managed services, define networking, security, and observability.
Deliverables
  • Documented target cloud architecture (compute, storage, network, security)
  • Cloud provider choice and justification (or multi-cloud strategy)
  • Network design: VPC, subnets, peering, VPN/Direct Connect

Frequently asked questions

Your questions, our answers

01 How much does a cloud migration cost and what is the expected ROI?
The cost depends on scope: number of workloads, dependency complexity, compliance requirements. Generally, ROI is achieved in 12 to 18 months through infrastructure cost reduction (25-40%), datacenter cost elimination, and team productivity gains. Our diagnostic phase includes a comparative TCO estimate over 3 years.
02 What is the average duration of a cloud migration?
From 3 to 9 months depending on complexity. A lift & shift of around ten servers can be done in 2-3 months. A migration with replatforming and modernization of complex legacy infrastructure takes 6 to 9 months. We favor a wave-based approach to deliver value quickly and reduce risks.
03 How do you guarantee zero downtime during migration?
We use proven migration strategies: continuous data replication (DMS, Change Data Capture), progressive DNS switchover, blue-green deployment. Each wave includes a full dry-run, go/no-go criteria, and a tested rollback plan. The site remains operational throughout the transition.
04 Should you choose a single cloud provider or a multi-cloud strategy?
It depends on your context. For most businesses, a primary cloud provider with a lock-in avoidance strategy (containers, IaC, open standards) is the best cost/complexity trade-off. Multi-cloud is justified for multi-jurisdiction regulatory constraints or pricing negotiation strategies.
05 How do you control cloud costs after migration is complete?
We implement FinOps discipline from the start: systematic resource tagging, per-project/team budgets and alerts, automated right-sizing, reserved instances, spot instances for tolerant workloads, automatic shutdown of non-prod environments. Monthly reporting and quarterly review.
06 Our teams lack cloud skills. How do you handle upskilling?
Knowledge transfer is integrated into every phase. Your teams participate in architecture decisions, Terraform code reviews, and production deployments. We provide complete operational documentation (runbooks, playbooks). Optionally, we offer AWS/GCP/Azure certification training.
