Exploring the transformative power of cloud networking in today’s IT landscape
As businesses seek scalable and efficient IT solutions, cloud networking offers flexibility and cost savings while enabling cutting-edge technologies

The world of technology is constantly evolving, and one of the most significant developments in recent years is an uptick in cloud networking. In an age where businesses are increasingly looking for scalable, flexible and efficient solutions to meet their growing IT needs, cloud networking has become a pivotal enabler of digital transformation. From enabling seamless connectivity across distributed networks to improving data accessibility, cloud networking is reshaping how organisations think about their IT infrastructure.

What is cloud networking?

At its core, cloud networking refers to the use of cloud-based resources to manage, control and facilitate network infrastructure and services. Traditional networking relied heavily on physical hardware like routers, switches and firewalls to manage traffic and security. In contrast, cloud networking moves these functionalities into the cloud, allowing organisations to leverage virtual resources managed through software.

The key components of cloud networking include:

- Virtual Private Networks (VPNs): Secure connections over the public internet to provide privacy and data security.

- Software-Defined Networks (SDNs): Networks managed by software rather than hardware, offering more flexibility and scalability.

- Network-as-a-Service (NaaS): A model in which businesses can subscribe to networking services hosted in the cloud rather than investing in physical infrastructure.

- Cloud-based firewalls and security protocols: Providing robust protection for cloud networks against emerging cyber threats.

Cloud networking is integral to a range of modern technologies and services, including the Internet of Things (IoT), remote work platforms and edge computing. It allows organisations to scale their networking needs according to demand, without the constraints of physical infrastructure – leading to more cost-efficient and flexible solutions.

Thriving in a cloud-based environment, where collaboration knows no bounds

Opportunities in cloud networking

The shift to cloud networking brings several opportunities for organisations, particularly in terms of scalability, flexibility and cost savings.

In traditional networking environments, scaling infrastructure to accommodate growth could be a time-consuming and costly process. Cloud networking, however, enables businesses to scale up or down their network capacity with ease. This level of agility is crucial for organisations that experience fluctuating traffic or seasonal spikes in demand.

According to a report by Gartner, by 2025, over 85% of enterprises will adopt a cloud-first strategy for networking, up from just 30% in 2020 –  highlighting the pressing need for businesses to maintain flexibility in their networking infrastructure.

Another compelling benefit of cloud networking is the cost savings it offers. Traditional networking requires significant investment in hardware, maintenance and energy consumption. Cloud, on the other hand, operates on a pay-as-you-go model, where organisations only pay for the resources they use.

A 2023 study by Forrester revealed that businesses migrating to cloud-based networking solutions can reduce their total network management costs by up to 45%. This makes cloud networking especially attractive for small and medium-sized enterprises (SMEs) that may not have the capital to invest in extensive physical infrastructure.

Security is a critical concern in today's digital landscape, and cloud networking offers enhanced protections against cyber threats. With the rise of cybercrime, cloud providers have invested heavily in robust security measures, including encryption, multi-factor authentication, and advanced firewalls.

Cloud networking is a key enabler of several emerging technologies, including IoT, AI, and edge computing. These technologies require low-latency, high-bandwidth connections that can scale dynamically based on real-time demands. Cloud networking's ability to distribute network functions across multiple locations and resources ensures that these new technologies can operate efficiently and securely.

A report by Cisco predicts that by 2025, there will be over 75 billion IoT devices connected globally. Without the capabilities offered by cloud networking, it would be impossible to manage the vast amount of data and connectivity requirements for these devices.

Challenges in cloud networking

While cloud networking brings substantial benefits, it is not without its challenges. While cloud providers offer advanced security features, the shared responsibility model of cloud services means that businesses are still accountable for securing their data and applications. Misconfigurations or insufficient security protocols can lead to vulnerabilities.

According to a report by Palo Alto Networks, 68% of businesses suffered a security breach related to a cloud-based service in 2022.

Vendor lock-in, meanwhile, remains a significant concern for businesses adopting cloud networking solutions. Once a company commits to a particular cloud provider, migrating to another platform can be both costly and complex. This lack of interoperability between different cloud vendors can limit an organisation's flexibility and make them reliant on the chosen provider’s pricing structure and service capabilities.

“Not all cloud solutions are created equal,”

Rahul Pradhan, VP Product and Strategy – AI, ML and Data at Couchbase.

“Inflexible pricing plans and issues with vendor lock-in are creating real budgetary challenges, impacting the overall effectiveness of the cloud. IT teams need to ensure they retain control and visibility, to limit a sprawl on resources and unexpected costs.

“The answer is services that give businesses more flexible options. Enterprises should also regularly monitor cloud usage and set up alerts, thresholds and clear policies that govern spending. These policies should be flexible enough to accommodate innovation at a rapid pace while maintaining cost control. In addition, there should be a culture of accountability. Every team using the cloud should be aware of the financial implications and optimise their usage. This shared ownership will help businesses minimise wastage and make cost control a collective effort.”

The future of cloud networking

The future of cloud networking is bright, with emerging trends and technologies set to further revolutionise the space. As 5G networks expand, the demand for cloud-based solutions is expected to increase exponentially. 5G will enable faster speeds, lower latency, and more reliable connections, allowing cloud networking to support an even wider range of applications and industries.

Additionally, edge computing is likely to play a more significant role in cloud networking. Edge computing involves processing data closer to the source, reducing the need for data to travel long distances to centralised cloud servers. This can significantly reduce latency and improve the performance of real-time applications.

AI and automation in cloud networking

AI and automation are set to drive the next wave of innovation in cloud networking. Automated network management solutions powered by AI can help businesses optimise their networks, predict and prevent outages, and detect security threats in real time. A report by McKinsey predicts that AI-powered network automation could reduce operational costs by up to 25% by 2025.

As cloud networking continues to evolve, the integration of AI, automation, and 5G technologies will further enhance its capabilities, offering businesses even more opportunities to innovate and grow. The key for organisations moving forward will be to embrace these advancements while navigating the complexities associated with the cloud networking landscape.

As Neil Lewis, Cloud & As-a-Service Sales Leader (EMEA) at Hitachi Vantara, says: “According to IDC, cloud costs have blown up in recent years to such an extent that they now make up approximately 30% of overall IT budgets worldwide. Effectively managing these costs is vital for businesses to prevent budget overruns and resource wastage.

“As cloud spending is set to continue to rise, integrating cost considerations into coding practices – an approach which encourages developers to optimise code for financial efficiency – is increasingly essential. Technologies like AI are improving this strategy by speeding up coding and enhancing efficiency, allowing developers to better align financial objectives with cloud resource utilisation.

“Enterprises should also implement robust governance, utilise automated tools for real-time monitoring and leverage cloud cost management platforms. Automated tools provide insights into resource usage, helping businesses identify underutilised resources to scale down or terminate, ergo optimising cloud spend. Regular reviews and optimisations of cloud deployments, choosing appropriate resource sizes and taking advantage of savings plans are also important strategies to keep costs under control.”
