Case Study: T-Mobile achieves flexible cloud performance validation with Emblasoft

How T-Mobile carried out flexible performance testing for its unique cloud environment

T-Mobile faced the challenge of validating vendor performance claims for its VoLTE and EPC network functions within its unique cloud environment. As operators shift to the cloud, vendors can no longer guarantee performance, requiring T-Mobile to conduct its own testing. Their challenge was to determine accurate performance metrics and system dimensioning, as initial vendor claims of 1 million concurrent users did not hold up under realistic conditions.

Emblasoft implemented a program of performance testing tailored to T-Mobile’s specific needs. By conducting tests on load, throughput, and intensity with realistic, asymmetric traffic patterns, Emblasoft provided clear, demonstrable results. This enabled T-Mobile to accurately dimension its system, provision the right amount of cloud capacity, and work with the vendor to iteratively optimize performance, ensuring the network was properly equipped to meet subscriber demands without overspending.
