Cloud architecture done right: landing zones, security and high availability
We design your architecture on Azure or AWS following the Well-Architected Framework — landing zone, networking and security, high availability and multi-region, scalability and governance — and deliver it as infrastructure as code (Terraform or Bicep) in your own account, not ours.
A well-designed cloud architecture defines how your accounts, networks, identities and workloads are organized on Azure or AWS before anything goes to production.
The starting point is a landing zone: the base structure of accounts/subscriptions, networking (VPC/VNet, segmentation, hybrid connectivity), identity and access (IAM), governance and security guardrails, on top of which your applications then run. We design against the five pillars of the Well-Architected Framework (operational excellence, security, reliability, performance efficiency and cost optimization), build in high availability and, when needed, multi-region for disaster recovery, and deliver everything as infrastructure as code with Terraform or Bicep. That makes your cloud reproducible, auditable and versioned — and it stays 100% in your own tenant or account, with no lock-in to us.

When you need it
What's included
Landing zone & account structure
We design the base: account/subscription hierarchy, environment separation (dev/test/prod), governance, tagging, policies and guardrails. The landing zone is the foundation your cloud grows on without becoming a mess six months later.
Network & security design
Network topology (VPC/VNet, subnets, segmentation), hybrid connectivity if you need it, and cloud security: least-privilege IAM, secrets management (Key Vault / Secrets Manager), encryption, resource hardening and tightly scoped security groups. We define what's exposed and what isn't.
High availability & multi-region (DR)
Multi-zone high-availability design and, when the case justifies it, multi-region for disaster recovery, with RTO/RPO targets agreed with you. We test the failure modes instead of assuming it'll "just be there".
Infrastructure as code (Terraform / Bicep)
The whole architecture is defined as code with Terraform or Bicep: reusable modules, remote state, parameterized environments and a reviewable plan/apply. Your cloud becomes reproducible, versioned in Git and auditable — no manual portal clicks.
Well-Architected Review
We review the design against the five pillars of the Well-Architected Framework (Azure or AWS): operational excellence, security, reliability, performance efficiency and cost. We deliver prioritized findings and a remediation plan, not just a diagram.
Data architecture & managed services
We choose the right data services (relational, NoSQL, queues, cache, storage), favoring managed services over hand-administered VMs, with backup, encryption and a retention strategy defined from the design.
Observability & operating model
We design how the cloud will be operated: centralized metrics, logs and traces, actionable alerts and runbooks. An architecture doesn't end at the diagram — we define how your team operates and diagnoses it the day something fails.
Scalability & cost governance
Sizing, autoscaling and service choices based on real load, with tagging and budgets so spend is visible and attributable. The goal is to scale when you need it and not overpay when you don't.
How we work
Discovery & requirements
We capture your workloads, security and compliance requirements, availability targets (RTO/RPO) and constraints. If you already have cloud, we assess the current state before proposing anything.
Architecture & landing zone design
We design the landing zone, network, identity and access model and the high-availability/DR strategy, documented with diagrams and architecture decision records (ADRs). We validate the design with you before coding.
Infrastructure as code
We implement the architecture as code with Terraform or Bicep in your own account: modules, remote state, environments and a plan/apply pipeline. It all lives in your Git repository from the first commit.
Well-Architected review & hardening
We review against the Well-Architected Framework, apply security hardening (IAM, secrets, encryption, exposure) and test the failure and recovery scenarios we agreed on.
Delivery & handover
We hand over the documented architecture, the IaC code, an operations runbook and a handover session. Everything lives in your tenant/account and your repository — 100% yours, with no vendor lock-in to us.
Tech stack
The tools and platforms we build it with — chosen for your problem, not for hype.
Frequently asked questions
Azure or AWS? Which one is right for me?
It depends on your context, not our preference. Weigh your current ecosystem (if you already live in Microsoft 365 and Active Directory, Azure usually fits better; if your team already operates on AWS, that learning curve is solved), the services you actually need, your budget and your in-house talent. We work both clouds and apply the corresponding Well-Architected Framework. We decide this during discovery with data, rather than assuming the answer up front.
Can you design a multi-cloud architecture?
Yes, but only when there's a real reason for it — for example, data sovereignty requirements, avoiding a single-vendor point, or leveraging a specific service from another cloud. Multi-cloud adds considerable operational, security and cost complexity, so we don't recommend it as a trend. In most cases a single, well-architected cloud (with multi-region DR within it) covers availability needs without that extra burden. We assess it honestly during discovery.
How do you handle security and compliance?
Security is one of the five pillars of the Well-Architected Framework and we design it from the start, not as a patch at the end: least-privilege IAM, secrets management (Key Vault / Secrets Manager), encryption in transit and at rest, network segmentation, resource hardening and governance guardrails. We document what's exposed and why. For specific compliance requirements we build them into the design as verifiable controls; we work with a CMMI Level 2 certified process and validate quality with our internal ARIA platform.
Why infrastructure as code and not manual configuration?
Because portal clicks aren't documented, can't be replicated across environments, and nobody knows what changed or who changed it. With infrastructure as code (Terraform or Bicep) your cloud is versioned in Git, reproducible (the same code stands up identical dev, test and prod), auditable (every change goes through a reviewable plan/apply) and recoverable in a disaster. It's the difference between an architecture you can operate and one you pray you never have to touch.
Do I own the infrastructure and the code?
Yes, 100%. Everything is deployed in your own Azure tenant or AWS account, not ours. The IaC code (Terraform or Bicep), architecture diagrams, ADRs, access and runbooks live in your Git repository from the first commit. There's no vendor lock-in to us: if tomorrow you want another team to operate it, you have absolutely everything you need.
