Public internet can't meet enterprise performance or security demands. MPLS-based private connectivity and a Network-as-a-Service model change that equation for cloud-bound workloads.

Why enterprises need more than a VPN tunnel

  • MPLS delivers Layer 2 speeds over Layer 3 networks with guaranteed SLAs and full network isolation, unlike public internet connections.
  • Co-located data centers in cities worldwide create direct private links between Telco networks and cloud service providers such as AWS, Azure, and GCP.
  • A multi-cloud network mesh lets enterprises centrally manage secured connectivity across CSPs without navigating each provider’s networking specifics.
  • Two NaaS pricing models, bandwidth-based and consumption-based, give enterprises the flexibility to match spend to actual cloud traffic patterns.

How it works

Think of MPLS as a private highway built for enterprise traffic. The public internet gets you there eventually, yes, but with unpredictable delays and no guarantee your data won’t share lanes with everyone else. For industries where network isolation and committed SLAs aren’t optional, that tradeoff is simply unacceptable.

Private cloud connectivity works through co-located data centers, physical exchange points where a direct link is established between the Telco’s MPLS network and a cloud service provider like AWS, Azure, or GCP. These co-lo facilities exist across cities and regions worldwide, enabling consistent private access to cloud environments without touching the public internet. Route exchange between the customer’s on-premises infrastructure and the cloud network happens at this junction, handled between the Telco router and the CSP router.

When a direct co-location link isn’t available, Telcos route through certified partners that maintain their own private CSP access. Either path preserves the network isolation enterprises need.

Two distinct use cases drive demand here. First, accessing publicly available cloud services like AWS S3 or Google Workspace through a private channel rather than a public URL. Second, extending on-premises networks into the cloud using private IP addressing, where enterprise applications in the cloud behave as though they sit inside the corporate network.

For enterprises pursuing digital transformation consulting or building out enterprise AI solutions across multi-cloud environments, this architecture is the foundation. Reliable, low-latency, isolated connectivity isn’t a feature request. It’s the prerequisite for everything that runs on top of it.

Services accessed through Secured Enterprise Network Connectivity

Not all cloud traffic is created equal. That’s the core tension enterprises face when they shift mission-critical workloads to platforms like AWS, Azure, and GCP: some data must move privately, some can tolerate a managed risk, and the network layer has to make that distinction intelligently.

Two categories of service drive most of this decision-making. Public services, think AWS S3, Google Workspace, or similar CSP-hosted offerings accessible via public URLs, don’t inherently require private routing, but enterprises that handle sensitive transactions or operate under strict compliance mandates can’t afford the exposure of public internet transit. Private connectivity to these services means data never leaves the secured MPLS fabric. That matters enormously for banking and financial institutions where real-time data integrity and regulatory accountability aren’t optional.

The second category is more architectural in nature. When the cloud functions as an extension of on-premises infrastructure, private IP addresses bridge both environments and Telcos handle the routing between them. These services are invisible to external networks by design. Think of it as a secure corridor rather than a public road.

Where this gets genuinely interesting is the multi-cloud dimension. Enterprises today rarely commit to a single CSP. They spread workloads across providers to build resilience, enable disaster recovery, and use each platform’s distinct strengths. Managing that connectivity centrally, without getting tangled in each CSP’s proprietary networking model, is where third-party distributed cloud systems and enterprise AI solutions for network automation are changing what’s operationally possible. The enterprise AI accelerator model Brillio brings to Telco partners makes that orchestration tractable at scale.

Secured multi-cloud network connectivity: need of the future

Enterprises don’t land on a single cloud and stay there. The architecture has evolved, workloads on AWS, backup on Azure, microservices talking across GCP, disaster recovery switching regions mid-incident. Multi-cloud isn’t a preference anymore; for most enterprises, it’s the operational reality.

But that complexity creates a genuine problem. Each cloud service provider runs its own networking model, its own routing logic, its own access controls. Managing security across all of them individually isn’t just inefficient, it’s a risk posture that’s hard to defend. What enterprise digital transformation actually demands here is centralized control, not three separate policies patched together.

The answer sits in third-party distributed cloud systems that extend private MPLS connectivity across all major cloud environments, AWS, Azure, GCP, through a unified multi-cloud network mesh. Traffic stays off the public internet. Security policy applies from one plane. And the network can be designed to support real operational needs: load balancing service requests across providers, keeping microservices communicating via APIs at scale, backing data from one CSP to another, or switching across regions when availability demands it.

For enterprises running enterprise AI solutions, the stakes are especially high. AI workloads produce and consume sensitive data continuously, and the infrastructure carrying that data needs SLA-backed performance, not best-effort routing. A secured multi-cloud network architecture is the foundation that makes serious enterprise AI development services viable, not just conceptually, but in production, at the latency standards mission-critical systems actually require.

Network-as-a-Service Business Model

Pricing is where the rubber meets the road for any NaaS offering. Two models define how Telcos structure network connectivity to cloud for enterprise customers, and the choice between them matters more than most buyers initially realize.

The bandwidth-based model is built for predictability. Customers receive a dedicated network port with committed capacity, which makes it the right fit when large, consistent data volumes flow to cloud environments like AWS, Azure, or GCP. Think financial institutions running real-time transaction processing or enterprises supporting digital transformation with AI workloads that simply can’t tolerate variable throughput.

The consumption-based model, on the other hand, trades guarantees for flexibility. Data plans range from pay-per-GB at the entry tier to multi-terabyte committed tiers, with per-GB pricing dropping as commitment levels rise. Customers can shift between plans as needs change. But here’s the tradeoff worth noting: because network bandwidth to the cloud is shared across subscribers under this model, guaranteed speeds aren’t part of the contract. Enterprises using ai automation services or running enterprise ai applications with latency-sensitive requirements should weigh that distinction carefully.

A third layer of cost also applies across both models. MPLS network services carry separate charges from the Telco, and cloud service providers may bill independently for their own network resource consumption. Understanding the full cost picture, not just the NaaS plan itself, is what separates a well-structured commercial agreement from a billing surprise six months in.

Brillio expertise

Two things set Brillio apart in the Network-as-a-Service space: the rare combination of deep engineering capability and hands-on commercial fluency that tier-1 carriers actually need to bring NaaS offerings to market.

On the engineering side, Brillio builds the full software stack that makes enterprise cloud connectivity real. Ordering and provisioning systems, subscription billing, UX interfaces for monitoring and managing cloud network links, and debugging tools that resolve routing conflicts between carrier and cloud provider networks. These aren’t advisory artifacts. They’re production systems running inside global telco environments.

But software alone doesn’t move a market. Brillio also owns the business layer. That means go-to-market strategy for NaaS offerings, pricing models calibrated to usage-based consumption, regional market intelligence for specific geographies, and direct product ownership of NaaS platforms including roadmap definition and enterprise customer engagement.

This dual capability reflects something broader about how Brillio operates across digital transformation consulting and enterprise AI solutions. Engineering rigor paired with commercial accountability. For hi-tech services and telecom clients navigating the shift to cloud-connected, software-defined networks, that pairing is what closes the gap between a compelling NaaS concept and a carrier-grade product that enterprises will actually pay for.

What enterprises and Telcos should take from this

  • Regulated industries like banking and financial services cannot treat public internet connectivity as acceptable for cloud-bound sensitive data.
  • Private cloud access splits into two types: public CSP services accessed via private routes, and on-prem network extensions using private IP addressing.
  • Multi-cloud strategies demand centralized network management; third-party distributed cloud systems make that viable across AWS, Azure, and GCP simultaneously.
  • Brillio’s engineering and go-to-market expertise spans ordering, provisioning, billing, and pricing strategy for NaaS offerings built on tier-1 carrier partnerships.
