Trusted Digital Transformation Partner
ROSTAN delivers end-to-end Microsoft Azure services — from landing zone design and hybrid connectivity via Azure Arc & ExpressRoute to full AKS Kubernetes orchestration, Azure DevOps CI/CD pipelines, and 24×7 managed operations backed by Microsoft CSP partnership. Whether you are modernising a legacy estate or building cloud-native from the ground up, our certified architects ensure every workload is secure, compliant, and cost-optimised from day one.
Azure Hub-and-Spoke VNet Topology
ROSTAN is a Microsoft Azure CSP Partner delivering six distinct Azure service lines from one team: Cost Optimization (reducing an existing Azure bill, no migration required), Managed Services (24×7 NOC operations on infrastructure that already runs), DevOps (Azure DevOps CI/CD and infrastructure-as-code), Infra Sizing (Well-Architected reviews and landing zone capacity planning), Development (building on Azure App Service, Functions and AKS), and Management (multi-subscription governance, Azure Policy and RBAC). Each is a separate engagement with its own scope.
Each is a distinct capability with its own scope. Engage one, or several — they are not bundled.
A standalone engagement — we do not need to have built your infrastructure to reduce what you pay for it. We audit your subscription against Azure Advisor recommendations, Reserved Instance and Azure Hybrid Benefit coverage, right-sizing, and orphaned resources. CSP licensing plus right-sizing typically delivers around a 20% saving on Azure spend that was never revisited after go-live.
Day-to-day operations on infrastructure that already runs — you do not need to migrate anything to bring us in. Our NOC team handles monitoring, patching, backup and disaster recovery, and incident response against an agreed SLA, so your own engineers stay off 2am alerts.
Where Managed Services keeps existing infrastructure running, DevOps changes how new releases get to it. Azure DevOps Pipelines, Repos and Boards integrated with AKS and App Service, so a release is a pipeline run with a rollback plan, not a maintenance window.
Distinct from Cost Optimization: this is about whether your infrastructure fits your workload, not just what it costs. We run Azure Well-Architected Framework reviews, size landing zones and AKS node pools against expected peak load, and set autoscaling thresholds before a launch, not after an outage teaches you where the ceiling was.
We also build on Azure, not only operate it. Cloud-native and serverless application development on Azure Functions, App Service and Logic Apps; API design and integration; and modernising a monolith into services that use Azure primitives instead of running an on-premises architecture on rented compute.
The governance layer above day-to-day operations: how your Azure subscriptions, access and policy are structured, not how any one workload runs. Multi-subscription landing zones, RBAC and Conditional Access, and Azure Policy guardrails that stop a misconfiguration from becoming an incident — set up once, then audited on a schedule.
The six service lines above are delivered using deep, hands-on capability across the full Microsoft Azure portfolio.
Structured cloud adoption from discovery to production cut-over using Azure Migrate, aligned to the Azure Well-Architected Framework and Cloud Adoption Framework (CAF).
Production-grade Kubernetes clusters on AKS with enterprise networking, GitOps-driven deployments, and automated scaling — from small teams to large multi-tenant platforms.
End-to-end software delivery using Azure DevOps Pipelines, Repos, Artifacts, and Boards — integrated with AKS and Azure App Service for fully automated, zero-downtime deployments.
Modern data platforms on Azure — combining managed databases, real-time ingestion, cloud-scale analytics, and global distribution for data-intensive enterprise workloads.
Comprehensive security posture management aligned to ISO 27001, SOC 2, and CIS benchmarks — using native Microsoft security tooling and RBAC-enforced least-privilege access.
ROSTAN's NOC team provides round-the-clock Azure infrastructure management, proactive monitoring, cost governance, and SLA-backed incident resolution — so your team stays focused on the product.
