Mobile VPC: Democratising mobile network routing with Stacuity VSlice
In cloud computing, developers expect full control over their network environments. Modern cloud platforms provide tools such as Virtual Private Cloud (VPC) functionality, allowing users to define routing, segmentation, and security policies with precision — without needing to rely on underlying infrastructure providers
Mobile networking, however, has traditionally lagged behind.
For decades, if you wanted to control how your devices routed data, you were reliant on monolithic Mobile Network Operators (MNOs) and static APNs (Access Point Names).
Stacuity is ending that era, bringing the same level of programmable control that cloud networking gave developers — to the mobile world.
Why Static APNs Are No Longer Enough
In traditional mobile networking, routing decisions are tied to Access Point Names (APNs), which are provisioned and controlled by MNOs, meaning:
- Enterprises have limited flexibility
- Changes require operator involvement impacting agility
- Routing logic is coarse-grained; you can’t easily segment one group of devices from another
This model creates a bottleneck, especially for IoT deployments and globally distributed applications that need dynamic, fine-grained control.
What is a VSlice? The Mobile VPC for Cellular Networks
Stacuity is shifting the ownership with our VSlice functionality.
What is a VSlice: A VSlice is a software-defined “slice” of the mobile core. It abstracts the underlying telecom complexity and hands the “steering wheel” to the developer.
This effectively virtualises mobile core routing in a way that mirrors what cloud-native VPC technology did for data centre networking. Instead of being locked into static APN configurations, users can define routing behaviour directly within the Stacuity platform.
This brings several cloud-native principles into mobile networking:
- Self-service control: Define routing logic without operator intervention
- Granular segmentation: Create virtual slices tailored to applications or devices
- Dynamic routing policies: Adapt traffic flows in real time
- Global consistency: Apply the same logic across regions and networks
This is comparable to how cloud VPC tools enable developers to design subnets, route tables, and gateways, all on demand.
The Benefits of Programmable Connectivity enabled by a VSlice
The shift from operator-controlled APNs to user-defined VSlice’s represents a fundamental change.
| Traditional Mobile Core | Stacuity VSlice |
|---|---|
| Operator-controlled | User-controlled |
| Static configuration | Dynamic, programmable |
| Limited flexibility | Fine-grained control |
| Slow to adapt | Agile and scalable |
For enterprises, especially those deploying IoT at scale, this unlocks new possibilities:
- Faster time to deployment
- Reduced dependency on MNOs
- Greater control over security and performance
- Seamless integration with cloud architectures
- Consistency over global deployments
The Future of Connectivity is Programmable.
Stacuity’s VSlice feature is part of a broader industry trend, the convergence of telecom and cloud networking models. By democratising control of the mobile core, it enables developers and enterprises to treat connectivity as programmable infrastructure.
VSlice brings the power of cloud-native virtual networking into the cellular world.
FAQs: Mobile VPC & Programmable Networking
A standard APN is a static, carrier-managed gateway that acts as a “dumb pipe.” Changes require manual operator intervention and weeks of lead time. Stacuity VSlice is a software-defined “slice” of the mobile core that you control. It replaces rigid carrier configurations with an API-driven interface, allowing you to manage routing, DNS, and security in real-time without touching the device settings.
Legacy MNO routing is a “bottleneck of permission” where every change depends on the carrier. Programmable connectivity shifts that control. By treating the mobile network as infrastructure-as-code, you can automate traffic steering, segment device groups, and integrate cellular traffic directly into your cloud architecture. It’s the transition from manual telecom tickets to instant, self-service network management.
