Modernisation in South African business should be anchored by cloud-native practices that deliver value across productivity, market relevance, and resilience.

Innovation remains a prominent priority on the corporate agenda, yet many modernisation initiatives fail to deliver their expected return on investment.

Licences are paid for, and platforms go live, but the environment often remains stagnant even as the business evolves around it. Costs increase, security configurations become outdated, and, by the time AI is introduced, the underlying architecture is often ill-equipped to support it.

According to Chris Badenhorst, Head of Azure Core, Data and AI Services at Braintree, this pattern has become familiar across South African businesses.

"Companies recognise the value modernisation offers, but they treat migration as the destination," he says. "The moment you stop actively managing your environment, you start losing ground."

The findings reinforce this assessment. The Auditor General of South Africa has flagged repeated ICT project failures in the public sector, with cost- and time-saving targets frequently unmet. Deloitte points to organisations that remain in pilot or migration phases, failing to progress from proof-of-concept initiatives to production-grade capability.

The PwC Africa Cloud Business Survey 2025 found that 89% of companies across Africa are refining their cloud approach in response to regulatory changes and geopolitical instability, while 88% are increasing their cloud budgets in the coming years. While cloud investment has accelerated across Africa, the modernisation of data architecture has not met the required metrics to support key business functions such as AI and cloud analytics. 

Investment does not guarantee modernisation

Long-term value depends on whether organisations have built environments capable of supporting a strategic outlook. 

Modernisation is recognised as a continuous process that demands active management of the environment well beyond the migration of workloads. As organisations evolve, their technology requirements change. Environments configured at go-live and left unmanaged can therefore accumulate both cost and risk over time. 

Structured frameworks help organisations move from migration to operational maturity and provide a basis for maintaining performance, governance and resilience.

The Azure Well-Architected Framework comprises five pillars: reliability, security, cost optimisation, operational excellence, and performance efficiency. It provides organisations with a structured approach to assessing the performance of their environments.

These pillars surface the decisions that erode value. Are workloads correctly sized for demand, or are clients paying for capacity they don't use? Are security configurations still relevant, or have they not been reassessed since go-live? Can the architecture withstand a power outage, or has resilience not been designed into the environment?

"The challenge is applying these assessments honestly," Badenhorst says. "You need to look at the mess behind the technology and address what your current environment isn't delivering."

Cost is often the catalyst for evaluating existing digital real estate.

Infrastructure decisions that were appropriate a few years ago may no longer align with current business requirements or operating conditions. The global chip shortage has made refreshing or replicating owned hardware more difficult to justify. On-premises setups that once seemed cost-effective no longer offer the same economic advantages as a well-architected cloud environment with elastic capacity.

Reviews of infrastructure costs often reveal broader shortcomings in how environments are configured and managed. Security is often one of the areas these assessments bring into focus. POPIA compliance requires a cloud posture that advances as regulations tighten and threat vectors shift, which is why the framework approaches security as a continuous discipline.

The South African operating environment places particular emphasis on operational excellence and performance efficiency. Power instability must therefore be considered in architectural design, as environments that fail to account for it are more vulnerable to disruption. Embedding resilience into architecture from the outset requires decisions that reflect both the technology and the business context.

AI exposes weaknesses that already exist

The organisations extracting value from AI are those with well-managed technology estates and sound architecture. IBM notes that AI models "not only inherit those weaknesses but can also amplify data issues at scale", reinforcing the importance of disciplined governance and ongoing stewardship of technology platforms.

An effectively governed Azure environment provides a foundation for AI capabilities without compounding existing problems. The ability to realise value from AI ultimately depends on the discipline applied to managing technology over time and preventing technical debt from accumulating.

Migration marks the beginning of modernisation. The return on technology investment is determined by the discipline applied after implementation.
