Cloud & Infrastructure Architecture
Reading time: 2 minutes.
Infrastructure Sized for Your Actual Load
Over-provisioned infrastructure burns budget every month for capacity nobody uses. Under-provisioned infrastructure falls over the first time traffic spikes. CimpleO designs cloud architecture around your real usage patterns and growth trajectory — not a generic reference architecture pulled from a vendor’s solutions page.
Cloud Architecture Design
We design infrastructure on AWS, GCP, or Azure around your actual traffic patterns, data volumes, and growth trajectory. VPC network design, compute strategy (EC2, ECS, Lambda, or Kubernetes — chosen on workload fit, not trend), storage tiering, and a scaling plan that holds under real load, not just the load test we ran once.
Infrastructure as Code
Every resource defined in Terraform or Pulumi and tracked in version control. Environments that are reproducible from a clean account, disaster recovery that’s been tested rather than assumed, and infrastructure changes that go through the same review process as application code.
Cost & Performance Optimisation
We audit existing cloud spend and performance against actual usage — right-sizing over-provisioned instances, implementing auto-scaling in place of static fleets, reserved capacity where usage is predictable, and CDN/caching layers where they’re missing. Most audits find 20-40% in cuts before any architecture change.
Migration & Modernisation
Moving off legacy hosting, consolidating multi-cloud sprawl, or migrating from monolith to containerised services — planned and executed with a rollback path at every stage. We migrate incrementally against a live system, not in a single high-risk cutover window.
What We Cover
- Compute — EC2/GCE/VMs, ECS/GKE/AKS, Lambda/Cloud Functions, chosen per workload
- Networking — VPC design, load balancing, CDN, DNS, zero-trust network access
- Storage & Data — S3/GCS/Blob Storage, database hosting strategy, backup and retention policy
- Security — IAM least-privilege, secrets management, encryption at rest and in transit, audit logging
- Observability — centralised logging, metrics, distributed tracing, alerting tied to actual on-call response

Frequently Asked Questions
Which cloud provider should we use?
Depends on your workload and team. AWS has the deepest service catalogue and the largest hiring pool. GCP is strong for data and ML workloads and often cheaper for egress-heavy products. Azure makes sense if you're already committed to the Microsoft stack (AD, .NET, Office 365 integration). We give a direct recommendation based on your actual constraints, not a vendor-neutral shrug.
We're on one cloud provider already — can you just fix what's there?
Yes, and that's the more common engagement. We audit the existing setup — cost, security posture, single points of failure, scaling ceilings — and fix the highest-value problems first. A full re-architecture is rarely the right first move.
Can you help us cut our cloud bill?
Usually. Reserved instances and savings plans, right-sizing over-provisioned resources, auto-scaling instead of static fleets, and killing idle resources typically cut 20-40% without touching architecture. Bigger savings need workload-level changes — we'll tell you which apply before you commit budget.
Do you design for multi-region or multi-cloud from day one?
Only if the requirement is real — data residency law, an SLA that demands it, or a client contract that specifies it. Multi-region and multi-cloud both add real operational cost. We build for the redundancy you actually need, not the redundancy that looks impressive in an architecture diagram.
How do you handle infrastructure security?
VPC network segmentation, least-privilege IAM policies, secrets management (AWS Secrets Manager, HashiCorp Vault), encrypted storage and transit by default, and audit logging on everything that touches production. We build to the compliance framework your industry requires — SOC 2, HIPAA, PCI DSS — from the architecture stage, not bolted on after a failed audit.
