Cloud
We design and deliver resilient, cost-optimised cloud platforms across Azure, AWS, and GCP. New landing zones or large-scale migrations, Cloudsa builds the foundation your enterprise runs on.
Overview
The era of "move to the cloud" is over. The companies winning today run cloud as an operating model: architecture, automation, security, and cost governance held to one discipline. They don't treat it as a one-off migration. Lift a rack of VMs into Azure or AWS and declare victory, and you've built a more expensive data centre that someone else owns.
Modern enterprise cloud comes down to a few non-negotiables. Everything is codified. Infrastructure lives in Terraform and Bicep, deployed through GitOps pipelines with ArgoCD or Flux, peer-reviewed like application code. Identity is the perimeter now. Entra ID, conditional access, and zero-trust networking replace the old castle-and-moat model. Workloads run on managed, containerised platforms (AKS, EKS, Azure Red Hat OpenShift, Karpenter), so your engineers work on product instead of patching. Cost is engineered in from the first architecture diagram, not discovered in a painful invoice three months after go-live.
This is the practice Cloudsa has built over a decade. We've migrated national transport data systems, hardened healthcare platforms holding sensitive patient records, and stood up multi-region fintech landing zones with automated disaster recovery. We apply the Azure Cloud Adoption Framework and the AWS Well-Architected Framework as defaults, not afterthoughts. First migration, stalled migration, or an estate that has drifted: we design for the long horizon. Platforms that scale predictably, stay secure under audit, and cost less to run next year than they do today.
Capabilities
Eight core capabilities, delivered end-to-end or as focused engagements. Greenfield landing zones, or rescuing a migration that has stalled.
Azure CAF and AWS Control Tower-aligned landing zones with hub-spoke networking, management groups, policy guardrails, and a secure baseline that every subsequent workload inherits.
Structured rehost, replatform, and refactor waves with discovery-driven dependency mapping, zero-downtime cutovers, and tested rollback plans. Business value lands incrementally, not at the end.
Workload-appropriate placement across Azure, AWS, and GCP with unified identity, networking, and governance, plus the abstraction layers that keep you free of vendor lock-in.
Lift-and-modernise legacy estates into containerised, event-driven, and serverless architectures. ARO, AKS, EKS, Karpenter, and managed services that cut operational toil.
Everything codified in Terraform and Bicep, delivered through GitOps with ArgoCD and Flux. Reproducible environments, peer-reviewed change, and a full audit trail of every deployment.
Tagging taxonomies, budget alerts, reserved-instance and savings-plan strategy, and continuous optimisation dashboards. Most clients see 30–50% cost reduction within six months.
RTO/RPO-driven DR designs, geo-redundant failover, Application Gateway and CloudFront edge resilience, and recurring recovery-testing programmes that prove your platform survives a bad day.
SLA-backed day-two operations: patching, observability, capacity planning, incident response, and proactive optimisation. We keep running the platforms we design when you want us to.
Platforms
We're certified and experienced across the three major clouds. We recommend the right platform for your context, objectively, not by commission.
Our strongest practice. We design and operate enterprise Azure tenants end-to-end: Azure CAF governance, Entra ID identity, AKS and Azure Red Hat OpenShift, API Management, Application Gateway, and the Microsoft Cloud Security Benchmark. The safer institutional choice for most financial and government clients in our region.
The deepest service catalogue and our platform of choice for native SaaS builds. We architect to the AWS Well-Architected Framework: Control Tower landing zones, EKS with Karpenter autoscaling, CloudFront, and the full IaC toolchain. Often the right fit for startups and fintech moving fast.
Where data and ML are the centre of gravity, GCP excels. We deploy GKE, BigQuery-centred data platforms, and Vertex AI workloads, integrated with the same governance and identity discipline we apply everywhere else. Strong for analytics-heavy and AI-first organisations.
Industries
We do our best cloud work in regulated, infrastructure-critical sectors. Heavy compliance and long timelines are where most teams come unstuck.
Zero-trust platforms and fleet-scale identity for transport operators handling thousands of vehicles and millions of daily transactions. Reliability isn't optional here.
Fleet-scale identity & SSO
Cloud migrations and security architecture for banks, fintechs, and payment processors. Audit-ready by design. Strong identity governance and segregated environments.
PCI-DSS & ISO 27001 ready
HIPAA-aware platforms and patient data protection for hospitals and digital health providers. Secure infrastructure across multiple sites. Compliance is where we start.
Patient data sovereignty
Citizen-facing platforms and internal systems for government and parastatals. We design for transparency and resilience. These systems need to run for years, so we build for that.
Sovereign deployment models
OT/IT convergence and edge platforms for energy providers and industrial operators. Secure remote operations across plant and grid. We connect the engineering side to IT.
OT/IT secure convergence
Platform engineering, multi-tenant security, and FinOps for software companies. We help you ship faster and keep production solid.

Methodology
We map your current estate: workloads, dependencies, data flows, identity, and cost. You get a written cloud assessment with a migration wave plan, a target landing-zone design, and a costed business case everyone signs off on.
We stand up the foundation: management groups, networking, policy guardrails, identity integration, security baseline. All in Terraform or Bicep. You see the architecture diagrams and per-environment cost projections before we build anything.
Delivery in phased two-week waves. Each wave is rehosted, replatformed, or refactored as appropriate, with automated cutovers and tested rollback. You get demo access and burn-rate transparency at every milestone.
Runbooks, observability, and team enablement at handover. Then optional SLA-backed managed operations: patching, DR testing, quarterly cost reviews, and continuous right-sizing so the platform gets cheaper and more resilient over time.
Outcomes
Year-long cloud engagements
Typical cost reduction in 6 months
Production incidents in last 24 months on managed platforms
FAQ
Depends on your team capacity, regulatory requirements, and existing investments. Multi-cloud sounds resilient but doubles your operational surface area. For most organisations under 200 engineers, a single primary cloud with a DR-only secondary beats active-active multi-cloud. We help you evaluate honestly. We won't push you to whichever vendor pays us most.
Discovery alone is usually 2–4 weeks. A focused 'lift and shift' of 20 VMs to Azure or AWS is 8–12 weeks. A complex migration including refactoring, network redesign, identity integration, and managed services adoption is 6–18 months. We deliver in phased waves so business value lands along the way, not at the end.
Azure has the strongest enterprise tooling and is well-supported by Microsoft in West Africa. AWS has the deepest service catalogue and is better suited for native SaaS builds. GCP excels at data and ML. For most Nigerian financial and government clients, Azure is the safer institutional choice. For startups and fintech, AWS often wins. We can help you decide objectively.
We design for sovereignty as a baseline. Azure South Africa North or AWS Cape Town for data residency. Customer-managed encryption keys (CMK) for everything sensitive. Private endpoints for storage and databases. Network egress controls. We can also deploy entirely within your existing on-premises or sovereign-cloud footprint where required.
FinOps from day one. Every architecture we design includes cost projections per environment. We use reserved instances, savings plans, and spot capacity where appropriate. We enforce tagging discipline, set up budget alerts, and run quarterly cost reviews on managed engagements. Most clients see 30–50% cost reduction within the first 6 months.
Let's talk about your migration, your architecture, and the operating model that keeps it secure and affordable.
