Cloud Architecture Consulting: AWS, GCP and Azure

AWS · Azure · GCP · Infrastructure as Code

All infrastructure defined as code and versioned in Git. Terraform/Pulumi for reproducibility. Multi-AZ for resilience. FinOps to keep costs under control.

Definition

Why is Infrastructure as Code non-negotiable?

Click ops = configuration drift. Manual changes nobody documents. "Snowflake" servers nobody knows how to replicate. When the server dies, knowledge dies with it.

The pattern: Terraform/Pulumi for provisioning, Ansible/Cloud-init for configuration, ArgoCD for workloads. Everything in Git, everything reviewable, everything versioned. A junior can rebuild production with "terraform apply". That's real resilience.

Infrastructure SLOs

Objectives we guarantee contractually.

  • 99.99% Availability
  • 100% IaC
  • EU Data residency

Why

IaC, Multi-AZ, FinOps

Enterprise cloud that doesn't break the bank

If it's not in Git, it doesn't exist. Terraform/Pulumi for total reproducibility. Multi-AZ for real resilience. FinOps so your cloud bill is predictable, not a surprise.

infrastructure/main.tf
# Multi-AZ EKS Cluster
module "eks" {
source = "terraform-aws-modules/eks/aws"
cluster_name = var.cluster_name
cluster_version = var.k8s_version
# Multi-AZ for high availability
subnet_ids = module.vpc.private_subnets
}
  • 99.99% Uptime
  • <15min RTO
  • -40% Savings

Summary

For the CEO

The business value of cloud architecture.

Well-designed cloud infrastructure isn't a cost, it's business insurance. When a server fails, how long to recover? How much does each hour of downtime cost? With Multi-AZ and RTO <15min, the answer is "we don't notice".

FinOps means your AWS/Azure/GCP bill is predictable, not a surprise. Full cost visibility by project, team, and service. 40% of typical cloud spend is avoidable waste.

GDPR compliance by design: servers in Frankfurt and Netherlands, encryption, audit logs, documented retention policies. Ready for audit without stress.

  • 99.99% Uptime
  • -40% Waste avoided
  • <15min Recovery

For the CTO

For the CTO

Cloud architecture in technical detail.

100% Infrastructure as Code: Terraform for AWS/Azure/GCP, Pulumi for complex cases. Remote state in S3/Azure Blob/GCS with locking. Reusable modules for VPC, EKS/AKS/GKE, RDS/Azure SQL/CloudSQL. Atlantis or GitHub Actions for automated plan/apply.

Production Kubernetes: EKS/AKS/GKE with managed control plane. Cluster autoscaler + HPA + PDB for resilience. ArgoCD for GitOps. Istio/Linkerd optional for service mesh. Sealed Secrets or External Secrets for secrets management.

Observability: Prometheus + Grafana or Datadog. Structured logging with Loki/CloudWatch Logs Insights. Distributed tracing with Jaeger/X-Ray. PagerDuty/OpsGenie for on-call rotation.

Who it is for

Is It for You?

Enterprise cloud architecture requires technical team and budget. If a VPS suffices, don't overcomplicate.

Who it's for

  • Companies needing to scale infrastructure predictably.
  • Organizations with compliance and auditability requirements (ISO, SOC2).
  • Technical teams ready to adopt Infrastructure as Code.
  • Businesses with mission-critical apps requiring high availability.
  • CTOs wanting to eliminate manual operations and "click ops".

Who it's not for

  • Small projects where a simple VPS covers needs.
  • Companies without budget for enterprise cloud services.
  • Teams without technical capacity to maintain IaC.
  • Businesses where a managed platform (Vercel, Railway) suffices.
  • Very early-stage startups where speed trumps scalability.

Risks and how we cover them

Risk Mitigation

How we protect your infrastructure.

  1. 01

    Mandatory Multi-AZ. Health checks with auto-recovery. RTO <15min documented and tested.

  3. 03

    Data loss

    Mitigation

    Automated backups with defined retention. Cross-region replication for critical data. Documented RPO.

FAQ

Technical Questions

What CTOs ask.

AWS, Azure or Google Cloud?

AWS: more mature ecosystem, more services, more compliance certifications. Azure: native integration with Microsoft 365 and Active Directory, ideal for enterprise environments. GCP: better pricing, native Kubernetes, unbeatable BigQuery. All three are excellent. We recommend based on case and existing stack.

Serverless or Kubernetes?

Serverless for: stateless functions, variable workloads, zero ops. Kubernetes for: stateful microservices, granular control, teams with expertise. Many architectures combine both. For Node.js APIs and microservices, we pair it with our Node.js development.

How do you guarantee 99.99% uptime?

Multi-AZ deployment, health checks with auto-recovery, load balancers with failover, DB replicas with automatic failover. 99.99% = 52 minutes of downtime per year. We achieve it through redundancy.

How do you comply with GDPR?

Servers in Europe: Frankfurt (AWS eu-central-1) and Netherlands (GCP europe-west4). Encryption at rest and in transit. Least-privilege IAM policies. Audit logging. Documentation ready for audits. It goes hand in hand with our cybersecurity services.

Do you offer multi-region architecture?

Yes. For critical applications we deploy across multiple European regions with data replication and automatic failover. RTO <15min for regional disaster scenarios.

What is FinOps?

FinOps is the practice of continuously optimizing cloud costs. We implement: 100% tagging, budget alerts, monthly reports, automated rightsizing, Spot/Reserved instance usage.

What if our team has no cloud experience?

We include knowledge transfer: documentation, runbooks, training sessions. Option for retainer where we operate together while your team learns.

How long does a typical migration take?

Landing Zone: 4 weeks. Monolithic app migration: 8-12 weeks. Refactor to microservices + K8s: 16-24 weeks. Includes testing and handover. If data platforms are part of the migration, we coordinate it with data engineering.
