In recent years, the landscape of data centre technologies has significantly transformed, shifting from the traditional hardware-based infrastructure to more flexible and efficient software-defined solutions. This change, driven by the increasing demand for scalable, agile, and cost-efficient computing resources in a rapidly digitised world, has brought numerous benefits. In this op-ed, Kayvan Karim delves into the journey of hardware-centric data centres. He explains how virtualisation, containerisation, and cloud computing have revolutionised data centre design, scalability, and efficacy.

Traditional Data Centres: The Era of Hardware Infrastructure

In the not-so-distant past, data centres were synonymous with massive physical servers, storage, and networking equipment housed in dedicated facilities. Once the gold standard, these environments were burdened with high capital costs, limited scalability, and resource inefficiencies. The exponential growth in data volume and the increasing complexity of business applications have made these traditional architectures obsolete. This stark reality underscores the need to embrace more modern, software-defined solutions.

The Rise of Software-Defined Data Centres (SDDCs)

To address the issues of hardware-centric data centres, the concept of software-defined infrastructure emerged as a game-changer. Software-defined data centres (SDDCs) are a paradigm shift. They decouple the management and control of data centre resources from the underlying hardware, enabling administrators to programmatically provision, manage, and orchestrate assets. This shift toward software-defined solutions has revolutionised how data centres are designed, deployed, and operated, offering unprecedented agility, scalability, and cost-effectiveness. These transformative benefits of SDDCs paint a promising picture for the future of data centre technologies. According to Precedence Research, the global software-defined data centre market size is expected to hit around USD 350.53 billion by 2032, poised to grow at a compound annual growth rate (CAGR) of 22.9% from 2023 to 2032.

Virtualisation: Empowering Data Centre Efficiency

Virtualisation, a key component of contemporary data centre technologies, has proven worth it. Allowing several virtual instances to run on one physical server significantly improves resource utilisation. This abstraction from underlying hardware systems regarding computer storage and networking capabilities provides greater flexibility and makes workload management easier. As per VMware estimates, virtualisation can reduce hardware and operational costs by up to 70%. This is a testament to its effectiveness and the reassurance it brings about the future of data centre technologies. Additionally, a survey conducted by Citrix revealed that 74% of companies experienced reduced IT expenditure due to virtualisation. This underscores the importance of virtualisation in enhancing data centre efficiency.

Containerisation: Driving Portability and Scalability

Containers have become popular for packaging applications in lightweight, portable environments. Unlike virtual machines, containers are based on the host operating system kernel; thus, they are resource-efficient and faster to deploy. Docker and Kubernetes containerisation technologies, among others, have been widely adopted, allowing organisations to build, deploy and scale applications with unprecedented speed and flexibility. According to Mordor Intelligence, the containerised data centre market size is expected to grow at a CAGR of 18.49% to reach USD 33.77 billion by 2029. This depicts a fast-growing trend of containers being used by many companies, where enterprises use software-defined solutions that could efficiently be utilised to streamline the management or deployment of such containers.

Cloud Computing: The Future of Data Centre Infrastructure

Cloud computing has fundamentally changed how organisations consume and deliver IT services by offering on-demand access to different computing resources over the internet, which can be used anytime needed. Public-private hybrid cloud deployments have also become increasingly common, enabling businesses to leverage upon scalability, flexibility, and cost advantages cloud technologies provide. According to Mordor Intelligence, the cloud computing market is expected to reach USD 1.44 trillion by 2029, growing at a CAGR of 16.40% during the forecast period (2024-2029). This shows that most firms are accelerating their adoption of clouds to enjoy benefits like agility scaling capabilities and cost savings from moving workloads into these platforms.

Embracing the Future of Data Centre Technologies

The transition from traditional hardware infrastructures to software-defined solutions in data centres signifies a complete change in how computing resources are allocated, administered, and optimised. Technologies such as virtualisation, containerisation, and cloud computing have made this shift possible, enabling organisations to construct adaptable and efficient data centre infrastructure. The future is likely characterised by software-defined data centres that bring with them new prospects for innovation, growth, and competitiveness in the digital age.

The evolution of data centre technologies holds an incredible prospect for businesses that want higher levels of efficiency, flexibility, and scalability within an increasingly analytic society. By taking advantage of recent developments in virtualisation, containerisation or cloud computing technology, corporations can prepare their data centre infrastructure for success in the digital age while making it more resilient at a relatively lower cost.

FIVE WAYS UAE WORKFORCE PLANNING IS CHANGING IN 2026

Published

on

The UAE is entering a more complex phase of workforce growth. Hiring momentum remains strong, with the country recording a Net Employment Outlook of 60% for Q2 2026, placing it among the strongest employment markets globally. Yet the main challenge for companies is whether their employment structures, immigration planning, compliance systems, and HR leadership can support growth at scale.

Aethra Advisory, a UAE-based global hiring strategy and mobility architecture firm, outlines five shifts companies should prepare for as compliance, immigration, and HR become more connected.

HR is becoming workforce architecture

HR can no longer be treated as an administrative function focused only on recruitment, onboarding, contracts, and employee relations. In 2026, HR leaders are expected to help design the workforce model itself. That includes where a company hires, which employment structures it uses, how talent moves across borders, and where compliance risk may appear. A hiring decision is now linked to visa eligibility, payroll structure, sponsorship, worker classification, relocation timelines, and long-term operating needs.

Many companies still hire first and address structure later. The consequences often emerge months afterwards, when employment models become costly, difficult to manage, or unable to support growth.

AI is entering recruitment and workforce planning

Companies are using AI to screen CVs, match candidates to roles, automate outreach, schedule interviews, assess skills, and generate workforce insights. Used well, it can make hiring faster and more consistent, especially in high-volume recruitment environments.

A 2025 field experiment involving around 37,000 applicants found that 54% of candidates assessed through an AI-assisted recruitment pipeline passed the final human interview, compared with 34% of candidates assessed through a traditional pipeline. However, AI does not replace human judgement. Companies still need clear hiring criteria, documented decision-making, oversight and an understanding of how recommendations are generated and reviewed.

Companies are moving into global talent systems

Many companies make the UAE a base for regional and international expansion due to its business-friendly policies and strategic location. Local companies are hiring across borders, global firms are entering the UAE, and leadership teams are being built across multiple jurisdictions. In fact, the cross-border workforce and migration solutions market is projected to reach $11.37 billion by 2033, growing at an annual rate of 11.8%.

For employers, hiring can no longer be treated as a local HR process. Companies must make deliberate decisions about how they enter new markets and engage talent. Some may use an Employer of Record to hire quickly, while others may establish a local entity to gain greater control. In some cases, relocating and sponsoring employees will be the right approach or engaging contractors or building a longer-term market entry structure may be more suitable. Each route carries different implications for cost, compliance, operational control, and future scalability.

Employment models are becoming more hybrid

As companies scale, informal arrangements become harder to manage. A single UAE business may now have locally sponsored employees, remote workers, consultants, contractors, relocating workers, etc. This gives companies more flexibility, but also creates operational risk when obligations are not understood from the start. Worker classification, payroll treatment, benefits, visa eligibility, contract terms, management control, and termination rules can vary depending on how a person is engaged. Employers need clear structures defining employment status, work location, applicable law, and how each relationship is governed.

Regulation is influencing hiring decisions

In the UAE, hiring depends on more than finding the right candidate. Companies need the right regulatory setup before they can move quickly. Licensing gaps, unclear sponsorship routes, incomplete documentation, or a mismatch between the role and the employment structure can still delay a strong hire.

This makes compliance and immigration planning an early hiring priority. Companies should understand the requirements before entering a market, confirming a hire, or committing to a relocation timeline.

He outlined how Nokia’s end-to-end portfolio spans everything from AI-ready connectivity and energy-efficient 800G data centre networking to intelligent, self-optimising home Wi-Fi experiences powered by AI.

A key focus of the discussion was Nokia’s shift from strategic advisory to real-world execution through its dedicated Automation Excellence Practice, helping operators translate ambitious transformation roadmaps into measurable outcomes. The conversation also highlighted the growing importance of integrated, intelligent and secure networks that can support rising AI workloads, eliminate infrastructure bottlenecks and unlock tangible business value, while maintaining the highest standards of security, privacy and resilience

Could you begin by telling us about your role at Nokia and the journey that brought you here?

I lead Nokia’s Advanced Consulting Services business across Europe, the Middle East and Africa. My journey with Nokia spans nearly seventeen years, beginning at a time when consulting was largely focused on network transformation initiatives. Over the years, I have worked closely with operators around the world on transformation programmes, analytics adoption, customer experience management and digital modernization.

As the industry evolved, so did our consulting focus. Following the Nokia and Alcatel Lucent merger, we established what is today known as Advanced Consulting Services. The organization now spans several domains, including security, business monetization, cloud and technology transformation, autonomous operations, and data and AI.

More recently, we launched an Automation Excellence Practice. The idea was simple. Customers often appreciated our strategic blueprints but needed practical expertise to implement them. Today, we have specialized engineers who combine telecom expertise, AI capabilities and software development skills to turn strategic visions into real automation pipelines, AI-driven workflows and production-ready use cases. Our role is to help customers move from concept to measurable business outcomes.

Nokia is often associated with connectivity, but the company is increasingly talking about AI readiness. How does Nokia’s infrastructure portfolio support this transition?

AI is creating what we describe as an AI supercycle. It is transforming everything from data centres and cloud infrastructure to network architectures and edge computing. Supporting this shift requires a complete ecosystem rather than isolated technologies.

Nokia’s portfolio addresses this across multiple layers. On the network side, we continue to innovate in radio technologies, including AI-RAN capabilities developed alongside strategic partners such as Nvidia. We also have a strong optical networking and IP portfolio that enables the high-capacity connectivity required between data centres, edge locations and cloud environments.

One area that excites me is our innovation in data centre networking. We are introducing highly efficient coherent optical technologies and advanced switching platforms that significantly reduce infrastructure footprints while improving performance and energy efficiency. These innovations are becoming increasingly important as organizations invest in AI factories, AI grids and large-scale inference environments.

Beyond connectivity, we also provide intelligent automation layers through our autonomous networking platforms, enabling operators to manage complex, multi-vendor environments more efficiently and intelligently.

What are some of the biggest infrastructure bottlenecks you see operators and enterprises facing as AI adoption accelerates?

One of the biggest challenges is understanding that AI infrastructure is not just about compute power. Organizations often focus heavily on GPUs and processing capabilities, but connectivity can quickly become the limiting factor.

You can deploy the most powerful AI infrastructure available, but if the network cannot support the required data movement between racks, data centres and edge locations, performance suffers. This is where intelligent networking becomes critical.

At Nokia, we are helping customers design what we call AI-ready connectivity. This includes high-capacity optical networking, intelligent routing and the seamless interconnection of compute environments. As AI workloads become increasingly distributed, the ability to move data efficiently becomes just as important as the ability to process it.

On the consumer side, Nokia has been showcasing AI-driven Wi-Fi management capabilities. How does this improve the end-user experience?

The home network has become far more complex than it was a few years ago. Consumers expect flawless connectivity across multiple devices, applications and services.

Our AI-enabled Wi-Fi solutions continuously monitor network performance and user experience. They can identify coverage gaps, detect congestion, analyze interference patterns and even recommend or automatically implement corrective actions.

The goal is to create a self-optimizing network environment where many issues can be resolved autonomously before they impact the user. This reduces support requirements for service providers while delivering a more consistent and reliable experience for customers.

The Middle East is witnessing an unprecedented surge in data centre investments. How do you see this shaping Nokia’s opportunities in the region?

The Middle East has emerged as one of the most dynamic markets globally for AI infrastructure investments. Governments and enterprises are actively investing in sovereign AI capabilities, advanced data centres and digital ecosystems.

This creates significant opportunities, not only for Nokia but for the broader technology industry. The success of these initiatives depends on having secure, scalable and efficient connectivity between compute resources, cloud environments and end users.

Our role is to help customers build these foundations. Whether it is data centre interconnectivity, optical networking, intelligent routing or autonomous operations, Nokia’s technologies are designed to support the scale and performance requirements of AI-driven economies.

As data volumes continue to grow, security and data sovereignty are becoming increasingly important. How is Nokia addressing these concerns?

Security is deeply embedded into Nokia’s strategy and innovation roadmap. As a European technology company, trust, resilience and security have always been fundamental principles in how we design and operate our solutions.

While we continue to invest heavily in AI innovation, we are equally focused on strengthening security capabilities across our portfolio. This includes advanced network security architectures, AI-driven threat detection and preparations for future technologies such as quantum-safe networking.

We are actively engaged with industry bodies, standards organizations and ecosystem partners to help define the next generation of secure digital infrastructure. As AI becomes increasingly pervasive, security must evolve alongside it, and that is an area where Nokia continues to invest significantly.

Looking ahead, what excites you most about the future of AI-driven networks?

What excites me most is the convergence of AI, automation and connectivity. Networks are evolving from passive transport layers into intelligent platforms that can learn, adapt and optimize themselves.

The future will be defined by autonomous operations, AI-native networks and real-time decision-making at scale. Organizations that successfully combine these capabilities will unlock entirely new business models and levels of operational efficiency.

For us, the opportunity is not just about deploying technology. It is about helping customers transform the way they operate, innovate and create value in an increasingly AI-driven world.

WHY AUDIO CLARITY MATTERS FOR THE CONTINUITY OF EDUCATION, WORSHIP, AND COLLABORATION IN THE MIDDLE EAST

Published

on

Spokesperson – Yassine Mannai, Associate Sales Director at Shure MEA

Across the Middle East, continuity is being shaped by the quality of connection people experience every day. In classrooms, places of worship, and collaborative workspaces, that connection often begins with one essential factor: audio clarity. At Shure, we recognised this gap early and understood its growing importance across these environments.

When sound is clear, people stay present. Students follow lessons more easily, engage with greater confidence, and absorb information with less strain. This becomes especially important in hybrid learning environments, where every participant needs to feel equally included, whether they are in the room or joining remotely. Research cited by Shure shows that poor audio affects one-third of all virtual meetings, while four out of five common video conferencing frustrations are linked to audio issues such as background noise, echo, dropouts, and difficulty hearing others.

The same reality carries into places of worship. The ability to hear with clarity shapes how messages are received, how people remain attentive, and how connected they feel to the moment itself. In these spaces, sound supports focus, presence, and the overall quality of the experience.

In workplaces and institutional settings, audio has become central to how teams communicate and make decisions. Strong collaboration depends on being able to hear and respond without friction. As hybrid work continues to reshape professional life, the need for dependable communication systems has become more visible. [1] Shure’s regional insight, referencing IDC research, notes that 67% of professional workers are now at least partially remote, underlining how important it is for institutions to support communication across distributed teams. That understanding has been reflected in the solutions across our portfolio, including the MXA920 Ceiling Array Microphone for hybrid learning, the MXA320 Table Array Microphone for collaboration environments, and the DCA901 Broadcast Microphone Array for places of worship, where audience capture can bring greater depth to livestream experiences.

Across the region, institutions are moving toward smarter, more adaptable spaces where audio performance, system simplicity, and digital integration work together more effectively. Reliable audio has become part of how organisations sustain engagement, support participation, and deliver a better experience for the people who rely on them every day.
