Cost surprises at scale
S3 egress, NAT Gateway and RDS Multi-AZ costs accumulate invisibly. We implement tag-based cost allocation, Savings Plans and S3 Intelligent-Tiering from the first infrastructure sprint.
EKS Terraform EU data residency SOC 2-ready
AWS Cloud Engineering Services for Production US and EU Workloads
AWS is the primary cloud for nine-plus production workloads we operate — ANT's PropTech marketplace on EKS, JoyJet's consumer social platform handling US and EU traffic, REHAU's B2B portal with multi-region data residency. Terraform-managed, GitOps-deployed, FinOps-monitored from day one.
We deliver AWS cloud engineering for product teams migrating from bare-metal or other clouds, SaaS operators scaling EKS workloads, regulated industries requiring EU data residency and SOC 2-aligned infrastructure controls, and AI teams integrating AWS Bedrock for GDPR-compliant LLM workloads. Terraform manages everything — no manual console configuration enters production. GitOps pipelines via Argo CD handle deployment; Prometheus and Grafana handle observability.
Challenges
Industry challenges we solve
IAM sprawl and privilege creep
Monolithic IAM roles with wildcard permissions fail SOC 2 audits. We baseline every role to least-privilege and enforce via SCP guardrails.
RDS upgrade lock-in
Major PostgreSQL or MySQL version upgrades on RDS require planned maintenance windows and sometimes trigger application compatibility work. We manage blue-green deployments to minimise downtime.
Multi-region data residency complexity
EU personal data must not land in US regions. We enforce this via SCP policies, Terraform variable sets, and DLP tagging — and test it in CI before any production change.
EKS node scaling latency
Cluster Autoscaler's scale-out latency spikes under bursty traffic. We replace it with Karpenter for sub-minute node provisioning with spot instance consolidation.
Observability gaps in serverless
Lambda cold-start spikes, SQS consumer lag and EventBridge failures are invisible without explicit instrumentation. We wire OpenTelemetry collector for all serverless entry points.

Why YuSMP
Why AWS teams choose YuSMP
Dual-region EU/US by default
EU data residency in Frankfurt, Dublin or Stockholm; US in us-east-1 or us-west-2. SCP guardrails prevent cross-region data leakage — enforced in code, not convention.
FinOps from day one
Cost allocation tags, Savings Plans recommendations and anomaly alerts are part of the initial infrastructure setup — not a retrospective fix after the first surprise bill.
SOC 2 evidence pipeline
CloudTrail, Security Hub findings, IAM Access Analyzer and Config rules feed directly into your SOC 2 evidence repository — reducing audit prep from weeks to hours.
FAQ
AWS FAQ
Which AWS regions do you use for EU data residency?
eu-central-1 (Frankfurt), eu-west-1 (Dublin) and eu-north-1 (Stockholm) for EU personal data. US data in us-east-1 and us-west-2. We provision multi-region stacks with data residency guardrails in SCP policies and Terraform variable sets — EU personal data never crosses to US regions without explicit DPA authorization.
EKS or ECS — which do you recommend?
EKS for teams already running Kubernetes tooling (Helm, Argo CD, Karpenter) or planning cross-cloud portability. ECS Fargate for teams that want container orchestration without Kubernetes operational overhead — simpler IAM, shorter time-to-production, lower cognitive load. We document the decision as an ADR.
How do you manage AWS costs?
FinOps from day one: AWS Cost Explorer with per-tag cost allocation, Savings Plans and Reserved Instances for stable workloads, Karpenter spot instance consolidation for EKS, S3 Intelligent-Tiering and Lifecycle policies for object storage, and CloudWatch anomaly alarms before bills surprise anyone.
How do you handle AWS IAM for SOC 2?
Least-privilege IAM roles per workload with no wildcard permissions, IAM Identity Center (SSO) for human access, Service Control Policies preventing root key use and region-unauthorised resource creation, CloudTrail in all regions with integrity validation, and automated IAM Access Analyzer findings in CI.
Can you migrate our on-premises infrastructure to AWS?
Yes. We run the Migration Readiness Assessment, use Application Discovery Service for inventory, AWS Database Migration Service for databases and Application Migration Service for server lift-and-shift. Typical milestones: discovery 2 weeks, proof-of-concept 4 weeks, production migration 8–16 weeks depending on complexity.
How do you implement AWS disaster recovery?
We design to the appropriate AWS DR strategy per workload RTO/RPO: Backup & Restore (cheapest), Pilot Light (DB replica + minimal compute), Warm Standby (scaled-down second region) or Multi-Site Active/Active (highest cost, near-zero RTO). All strategies tested with GameDay exercises.
Do you use AWS Bedrock for AI workloads?
Yes. Bedrock provides Claude, Llama and Titan models with no data leaving AWS — useful for EU AI Act compliance where data residency and ZDR are requirements. We integrate Bedrock through LangChain with the same eval harness we use for OpenAI integrations.
