/solutions/cloud-infrastructure
South African enterprises need cloud infrastructure that meets local data sovereignty requirements. OAS delivers Microsoft Azure from Johannesburg and Cape Town data centres, Nutanix hyper-converged infrastructure for on-premises and hybrid workloads, and properly configured Microsoft 365 security and productivity. We bridge the gap between platform capability and the expertise needed to secure and optimise it for your business.
# Cloud and Infrastructure Solutions
Microsoft Azure. Nutanix HCI. Microsoft 365. The platforms your organisation depends on — configured, secured, and managed by a trusted partner with over 40 years of enterprise IT experience.
The Configuration Gap
Most South African businesses already pay for Microsoft Azure and Microsoft 365. Many have Nutanix or similar infrastructure on-premises. Yet the majority use a fraction of the capabilities available to them.
M365 security policies sit at defaults. Conditional access is not enforced. Azure resources are provisioned without cost controls. On-premises infrastructure runs on ageing hypervisors with escalating licence costs.
You are paying for enterprise capability. You are getting basic functionality.
OAS closes the configuration gap. We deploy, secure, and manage your cloud and on-premises infrastructure so you get full value from every rand spent.
Microsoft Azure
Azure is the only global hyperscaler with South African data centres. Your data stays in-country. Your workloads run on enterprise-grade infrastructure. POPIA compliance is built into the foundation.
South African Data Centres
- South Africa North (Johannesburg) — primary region with Availability Zones for high availability and fault tolerance
- South Africa West (Cape Town) — secondary region for disaster recovery and geographic redundancy
Local data centres mean your data never crosses South African borders. Data sovereignty is guaranteed by infrastructure, not by contract.
Azure Migration and Management
OAS manages the full lifecycle — assessment, planning, execution, and ongoing optimisation:
- Workload assessment — evaluate on-premises applications for cloud readiness
- Migration execution — lift-and-shift, re-platform, or modernise workloads on Azure SA infrastructure
- Cost optimisation — right-size resources, implement reserved instances, and enforce spending controls
- Ongoing management — monitoring, patching, security, and performance tuning
Hybrid Identity With Microsoft Entra
Most SA enterprises run hybrid environments — on-premises Active Directory synchronised with Microsoft Entra (formerly Azure AD). OAS configures conditional access, multi-factor authentication, privileged identity management, and device compliance policies. One identity. Secure access across on-premises and cloud.

OAS does not simply enable Microsoft 365. We configure it correctly from day one and manage it ongoing.
Most organisations use less than 30 percent of M365 capabilities. Email works. Teams works. SharePoint is half-configured. Security policies remain at defaults. Compliance features sit untouched.
OAS activates the full M365 security and productivity stack:
- Conditional access policies — enforce device compliance, location restrictions, and risk-based access controls
- Data loss prevention (DLP) — prevent sensitive data leaving your organisation via email, Teams, or SharePoint
- Microsoft Defender suite — Defender for Endpoint, Office 365, Identity, and Cloud Apps — deployed and tuned, not left at factory settings
- Compliance and retention — eDiscovery, audit logging, and retention policies configured for POPIA, FSCA, and PCI-DSS requirements
The M365 Audit
Already running Microsoft 365? OAS audits your current deployment and activates the security, compliance, and productivity features you are already paying for. Most organisations discover significant untapped value within their existing licences.
Nutanix Hyper-Converged Infrastructure
Traditional data centre architecture requires separate servers, storage arrays, and hypervisors — each from different vendors, each with its own management console and licensing model. Nutanix converges compute, storage, and virtualisation into a single software-defined platform.
AHV Hypervisor — No Licence Fees
Nutanix AHV is a licence-free enterprise hypervisor included with every Nutanix deployment. For organisations evaluating their VMware position following Broadcom's acquisition and aggressive licensing changes, AHV provides a proven, cost-effective alternative.
Citrix-on-Nutanix
The Citrix and Nutanix integration is a validated reference architecture. Native Prism Central host connection enables Citrix DaaS and CVAD to manage virtual desktop infrastructure on Nutanix AHV with multi-cluster support. This is the preferred infrastructure for enterprise Citrix deployments moving away from VMware.
Prism Central Management
One console for all your infrastructure. Multi-cluster management, capacity planning, predictive analytics, and one-click non-disruptive upgrades. Your infrastructure team manages everything from one place.
Explore Nutanix HCIData Sovereignty and Hybrid Architecture
South African enterprises face a dual requirement: harness cloud scale while keeping sensitive data within national borders.
OAS designs hybrid architectures that address both needs:
- Azure SA regions for cloud workloads with guaranteed data residency
- Nutanix on-premises for workloads requiring physical control and air-gapped environments
- Nutanix Cloud Clusters (NC2) to extend on-premises infrastructure to Azure for disaster recovery and burst capacity
- Citrix DaaS spanning on-premises and cloud from a single management plane
Every architecture decision considers POPIA, industry-specific regulations, and your organisation's risk posture.
