Telecom Operators and the Hybrid Cloud Strategy That Fits Them

Telcos in Bangladesh face a different cloud equation than banks: ten-year asset cycles, BTS edge sites, and CAPEX-heavy P&Ls. The hybrid model has to fit those numbers.

Telcos and banks both face strict residency posture, but the similarity ends there. Five-to-ten-year asset cycles, thousands of edge sites, and lawful- interception obligations reshape every cloud decision.

A four-tier hybrid that telcos converge on

The shape works whether the telco planned for it or not
1
Customer-facing edge Tier 1

CDN caches · uMEC · 5G UPF · DPDK/SR-IOV bare metal at BTS shelters

2
Regional sovereign cloud Tier 2

OSS/BSS · CRM · billing feeds · churn data lake · BDIX-peered, BDT-billed

3
National private cloud Tier 3

HSS/HLR · MSC · IN/charging · still bare-metal NFV in most cases

4
Selective public cloud Tier 4

Burst analytics · frontier ML · global SaaS · out-of-country DR
