Cloud and DevOps engineering for telecom-scale products

Why is telecom scale different?

Because the user count arrives all at once. A product sold through an operator does not grow a thousand users a week; it is switched on for a subscriber base and promoted in a campaign, and the first day’s traffic can exceed what a start-up sees in its first year. The users did not choose the product, so they do not forgive it: an upload that fails or a login that times out becomes a support call to the operator, and the operator calls the vendor. Capacity has to be right before launch, and the systems that absorb the surge (sign-up, authentication, sync, media) have to be designed for it rather than scaled into it.

What did scaling consumer services for T-Mobile, Verizon and TMcell teach us?

Three things that now run through every engagement. Plan capacity from the operator’s numbers and load test to the breaking point before launch, because the breaking point is the only number that matters on the day. Design for the surge, not the average: the queueing, backpressure and graceful degradation that keep a service answering when a campaign lands. And treat the operator’s security and integration review as part of the schedule, because it is the gate a launch date actually depends on. The outcome of that work, serving millions of users across three carriers, is described in the telecom case study.

What do operators ask vendors for before launch?

A security review that covers identity, data handling, encryption and incident response, with evidence rather than assurances. An integration that fits the operator’s billing, provisioning and support systems. A capacity statement with the load test behind it. A runbook for the launch: who is on call, what is monitored, how a rollback happens. And a commitment on availability that the vendor can actually measure. We have prepared vendors for those reviews and operators to run them; the work is the same from either side.

Which services apply?

Kubernetes consulting for the clusters that absorb the surge. Real-time infrastructure for the products built on WebSockets and WebRTC. SRE consulting for the SLOs, the on-call and the capacity plan. Cloud migration for the systems still on-prem that the launch depends on. Most telecom engagements combine two of these under one plan.

How does an engagement run?

A discovery call to understand the product, the operator relationship and the launch date. An assessment of the system against the launch’s numbers, with the gaps ranked by what fails first. The implementation with your team, including the load tests and the operator review preparation. A handover with the launch runbook and the on-call setup. Pricing follows the discovery call, once we know the scope.
