SDCI vs cloud hub architectures: What’s best for multi-cloud connectivity?

What are cloud hubs in the context of network connectivity?

In the era of digital transformation, enterprises are embracing multi-cloud environments to achieve greater agility, flexibility, and resilience. Yet, as organisations connect to multiple cloud service providers, maintaining consistent performance, visibility, and control becomes a growing challenge. This is where cloud hubs come into play.

Cloud hubs are strategic interconnection points that enable enterprises to connect multiple cloud environments through a centralised, high-performance network node. Think of them as digital airports that route traffic between different cloud providers and enterprise networks efficiently. They are typically hosted within major data centres and allow enterprises to establish direct and private connections to multiple cloud platforms such as AWS, Azure, Google Cloud, and Oracle Cloud.

For businesses seeking simplicity, cloud hubs offer a straightforward way to establish secure and scalable connections without the unpredictability of the public internet. They enhance reliability, reduce latency, and provide better security compared to traditional VPN-based setups.

However, while cloud hubs provide a strong foundation for cloud connectivity, they can sometimes lack the agility and programmability that modern enterprises need for dynamic workloads, especially when dealing with real-time application scaling or global expansion. That’s where SDCI comes into the picture.

What is SDCI, and how does Tata Communications enable it?

To understand how enterprises can go beyond basic interconnection, it’s essential to ask: What is SDCI?

Software-Defined Cloud Interconnect (SDCI) is an intelligent, software-driven network architecture that enables automated, secure, and on-demand connectivity between enterprise networks and multiple cloud providers. Unlike static cloud hub models, SDCI is designed to be flexible and adaptive, allowing enterprises to instantly create or scale cloud connections as business needs evolve.

Tata Communications has been at the forefront of this evolution through its IZO™+ Multi Cloud Connect platform. This SDCI solution provides a unified and seamless way to connect to multiple clouds via a single platform, eliminating the complexities of traditional cloud networking.

IZO™+ Multi Cloud Connect, businesses can:

• Set up cloud connections in less than ten minutes.
• Configure bandwidth on a simple platform interface.
• Scale network capacity or virtual network functions in minutes.
• Optimise performance and reduce data egress costs by up to 40%.
  
  

The platform is powered by Tata Communications, which brings automation, flexibility, and deep visibility into network performance. This approach replaces the need for manual provisioning and offers enterprises true agility.

By delivering cloud connectivity as a service, Tata Communications allows organisations to focus on innovation rather than infrastructure management. Businesses benefit from a reliable, scalable, and secure foundation that supports today’s multi-cloud strategies effortlessly.

Cloud hubs vs SDCI: Which suits multi-cloud network strategies?

When evaluating cloud hubs vs SDCI, it is essential to understand how each aligns with an enterprise’s connectivity strategy.

Cloud hubs are ideal for enterprises looking for a stable and centralised model to connect to multiple cloud providers. They provide consistency and simplicity, especially for organisations that need predictable, long-term connectivity. Cloud hubs reduce dependence on the public internet, improving latency and security while offering a solid base for multi-cloud operations.

SDCI, on the other hand, is purpose-built for dynamic and distributed workloads. It provides the agility and automation that modern digital enterprises demand. SDCI uses a software-defined framework to allow instant provisioning of connectivity, giving businesses the ability to respond rapidly to changes in demand, application performance, or global reach.

Tata Communications bridges the gap between these two models through its IZO™+ Multi Cloud Connect platform, which combines the reliability of traditional cloud hubs with the agility of SDCI. This enables enterprises to experience fast, easy cloud connections in less than ten minutes, manage bandwidth on demand, and enjoy transparent visibility across multiple cloud environments.
