The Cloud-native computing for telcos: definitions, challenges and opportunities

The Cloud-native computing for telcos: definitions, challenges and opportunities

Communications service providers (CSPs) are weighed down by the legacy software architecture that proliferates across their organisations, including in their foundational asset, the network. This software has not been designed for digital service provider (DSP) infrastructure – the cloud – and CSPs software capabilities are uncompetitive with those of web-scale companies. Those CSPs aiming to become treu DSPs must adopt cloud–native computing across their businesses.


EXECUTIVE SUMMARY

Mastery of cloud-native computing is critical for DSPs, but adoption is fraught with challenges

Telco industry players should prioritise cloud-native computing if they are committed to becoming DSPs

Key recommendations

IS BECOMING A DSP THE RIGHT STRATEGY?

Not all CSPs are willing or able to transform themselves into DSPs

DSPs expect to gain significant business benefits over other types of telco, but need a strong appetite for risk

UNDERSTANDING CLOUD-NATIVE COMPUTING

The principles of cloud-native computing have developed over the past 5 years and its definition is still evolving

Microservices oriented: Applications need to be developed as, or refactored into, microservices

Containerised: Applications must be packaged in containers

Dynamically orchestrated: Application containers must be centrally and dynamically orchestrated

ACCELERATING CLOUD-NATIVE ADOPTION

True believers must do more to accelerate their own rate of adoption, while hybrids have a vested interest in accelerating that of their vendors

Key telco barriers to cloud-native computing must be understood and addressed before mainstream adoption can take place

Selecting the right base technologies is tricky in a fragmented ecosystem, but the current winners are emerging
