The Hidden Cost of Running Your Own Edge
As more companies look for ways to improve performance, reduce latency, and build differentiated digital experiences, the idea of “running your own edge” has become increasingly attractive. At first glance, it sounds empowering: full control over routing, policy, hardware, and performance tuning. No dependency on a third-party platform. Your own network, your own rules.
But the reality is far more complex. What looks like independence on paper quickly becomes a sprawling ecosystem of responsibilities that few organizations are truly prepared for. Whether you’re building global POPs, managing a hybrid presence, or just trying to move workloads closer to users, the hidden costs add up fast.
Here’s what teams often underestimate.
1. The Operational Overhead Is Enormous
Running your own edge means you’re now on the hook for everything:
Hardware lifecycle management
Regional provisioning and deprovisioning
Peering relationships
Transit negotiation
Vendor management across dozens of markets
Deployment pipelines for networking changes
24/7 on-call rotations for global traffic
Even small issues — like a route leak in one region or a BGP flap coming from a peer — can force your entire team into an emergency response mode. The complexity increases exponentially with each additional POP.
2. BGP Is Expensive… and Unforgiving
Operating your own anycast network isn’t just about announcing routes. It’s about maintaining routing hygiene, monitoring for hijacks, keeping IRR/RPKI up to date, and tuning local preference and MEDs across upstream providers.
None of that is “set and forget.”
Even seasoned teams experience surprises: asymmetric routing in unexpected markets, route dampening after an incident, or traffic patterns shifting due to upstream policy changes you didn’t control. Each one can create user-perceived latency spikes or outright outages.
3. The Human Capital Cost Is the Real Killer
Running edge infrastructure requires highly specialized engineers:
Network architects
Routing experts
SREs who know how global anycast behaves
Traffic engineering specialists
Hardware and colocation operations staff
Security engineers with deep packet and transport-layer experience
These people are rare, and they’re expensive. And when something breaks at global scale, you suddenly need multiple of them — at the same time.
Keeping a team like this staffed, trained, and retained becomes one of the most substantial ongoing costs.
4. Outages Don’t Just Happen at the Core
When most companies run infrastructure in cloud regions, they deal with a more centralized failure domain. At the edge, the entire world becomes your failure domain.
Anything can take you down:
A fiber cut in a remote region
Capacity constraints at an upstream peer
A misconfigured BGP community during a rollout
A silent hardware failure in a POP that suddenly becomes a traffic hotspot
An exhaustion event — TLS handshakes, connections, CPU, memory — because a traffic spike was routed your way
Multi-region failure complexity is one thing. Multi-continent failure complexity is another level entirely.
5. Capacity Planning Is Never Perfect
The edge doesn’t behave like the cloud. Traffic is messy, unpredictable, and deeply influenced by:
ISP routing decisions
Regional events
Abuse traffic
Cache hit ratios
Protocol behaviors (like QUIC retries)
Peering policy changes
You’re responsible for having enough compute, bandwidth, and redundancy in every location — even for usage spikes your analytics never predicted.
Under-provision and you cause user latency. Over-provision and you bleed money.
There’s no perfect middle ground.
6. You Inherit Global Security Responsibility
Once you operate at the edge, you’re the front door for the world.
That means taking on:
Global DDoS mitigation
TCP/UDP flood resistance
Web application security controls
Bot management
Network-level anomaly detection
Abuse reporting and takedown processes
Managing threat intelligence pipelines
These systems aren’t optional. They’re the difference between a stable platform and a global outage.
The cost of building and maintaining them is often multiple times higher than teams expect.
7. Control Planes Become a Silent Risk
Traffic serving is only half the battle. Your control plane — the system that propagates configurations, deploys policies, updates edge logic, and distributes certificates — becomes mission-critical.
And it must be:
Fast
Consistent
Secure
Safe to roll out globally
Able to handle eventual consistency across hundreds of nodes
A control-plane bug at the edge doesn’t just break one cluster. It breaks everything, everywhere.
This is why the most experienced edge providers invest heavily in automated validation, staged rollouts, config linting, and global safety rails. These systems take years to mature.
8. The Economics Are Counterintuitive
Companies assume owning the edge is cheaper than buying one. In reality, the economics flip when you consider:
Global transit costs
Colocation fees
Power, space, and hardware refresh cycles
Burst capacity
On-call staffing
Observability tooling
Security systems
Compliance requirements
The cost of mitigating a single global failure
The money you save on vendor fees is quickly absorbed by operational complexity, capital expenses, and the human cost of maintaining a worldwide footprint.
9. Most Teams Eventually Reconsider
Organizations that build their own edge almost always reach the same conclusion: they want to keep certain performance-critical workloads close to the user, but they don’t want to run the full global footprint themselves.
This is why hybrid models are becoming the norm. Companies keep control over the parts that differentiate them — like routing logic, proprietary compute, or custom traffic flows — while leveraging managed edge networks for global reach and resilience.
It’s not about giving up control. It’s about putting your resources where they matter most.
Running your own edge sounds empowering — and in some ways, it is. But the hidden costs are real, persistent, and often underestimated. The edge is a living system, influenced by global network behavior, unpredictable routing decisions, and constant operational pressure.
Before committing to the build-your-own path, companies should have a clear understanding of what it takes to operate a global network safely, efficiently, and resiliently. For most, the smartest strategy isn’t full ownership or full outsourcing — it’s a thoughtful combination of both.
