7. CLOSING THE GAP ON TWILIO
FROM A TELECOMS PERSPECTIVE?

8. MY TELECOM’S PERSPECTIVE.
§ The ”Twilio gap” from an operator perspective is more than just numbers
§ Operators do more than just communications, and there are no really any numbers for a heads-on comparison
§ The biggest difference in the assets from a Telco and Twilio: You can touch them.
§ The potential of intercarrier wholesale - see the 2018 Annual Report:
8 https://bericht.telekom.com/geschaeftsbericht-2018/serviceseiten/downloads/files/financial_statements_dtag_gb18.pdf
It may not be fully comparable, but helps
to set the context J

9. WHAT IS RELEVANT IN THIS DISCUSSION
FROM A TELCO VIEW?
§ Legacy Telco communication service production
§ Is (still) a classic NT business supported by IT systems (OSS/BSS)
§ Is mostly a local business supported by intercarrier production & relations
§ Is closed community, long-term regulated, needs IC agreements
§ Is a highly dependent multi-player ecosystem mainly driven by standards
§ Is physical, with some core network components being virtualized
§ Modern alternative CSP communication service production
§ Developed as an app economy play by modern software companies
§ Is global for only a handful of relevant market players
§ Is walled garden, operating in grey zones
§ Low external dependencies due to End-to-End service, sometimes leveraging commercial breakout
§ Is entirely virtual, enabled by software, connectivity & the cloud
9

10. WHERE DOES CPAAS FIT?
§ CPaaS is an API enabler on top of Telco assets augmented with various features to enable programmable telecoms
§ Most providers aggregate these assets from various Telco’s
§ Some already integrate alternative communications provider’s assets
§ CPaaS technology follows paradigms driven by software companies
§ Virtualized/Cloud based global production with focus on local markets
§ Fast, automated provisioning and billing
§ Modern consumers with usually a variety of different choices
§ Standards are not relevant to get started; we see reverse standardization (i.e. best practice will win)
§ Telco’s as well as CPaaS players both need to comply with local regulations (at least reg. Telco assets)
§ CPaaS’ value creation is in the API abstraction and value of use cases, less volume alone

12. CPAAS – A CURSE OR A BLESSING FOR TELCO’S?
§ Forecast for worldwide voice & messaging CPaaS market to grow from 2bn USD in 2017 to 10.9 bn USD in 20221
§ Big demands in ongoing “digital transformation projects” from previously plain access to communication assets to more
business and process supporting functions based on communications features
§ Carriers are slowly getting started with CPaaS (see next slides), while established providers already move to offering vertical
specific functions and advanced service features beyond API access
§ Market capitalization increases by major CPaaS providers (e.g. mid 2017 to mid 2019 Twilio 3bn à 18.6bn USD)
§ Twilio and other CPaaS providers are a new kind of competition that captures values on top of Telco’s
§ Double-sided sword: The providers bring traffic, but also abstract and capture both value and the customer
§ CPaaS is evolving as the “Telecommunications Support System (TSS)” of many applications & services, while making the
role of Telco’s themselves less relevant
§ Wait, what?

13. CPAAS – THE TELECOMMUNICATIONS SUPPORT SYSTEM
§ Formerly produced end-to-end NT services Telephony and SMS supported by an operations stack and
business applications that are consumed only in devices or applications dedicated for this purpose are still
there and relevant
§ Connect people and have a basic communications system as part of it
§ This stack will remain and will be minimized/optimized
§ The future value lies in the gateway function
§ Create improved service experiences for the end customers
§ Easily expose enablers to have providers focus on their core business
§ Business-process supporting communications enablers that are produced with a modern IT infrastructure
and paradigms that can be integrated almost anywhere (apps, flows & processes, devices) will evolve
§ Exposing classic NT services (telephony, SMS) & endpoints, but also providing Internet communications enablers (e.g. messaging, WebRTC
voice & video, E-mail) and capabilities (e.g. transcoding)
§ Fully API driven – enablers as well as provisioning, lifecycle, billing, integration

14. HOW CAN THE CXTECH PARADIGM HELP?
§ “CXTech
§ where C stands for Connectivity, Communications, Collaboration, Conversation, Customer
§ for Experience because that’s what matters
§ and Tech because we’re Enablers”
§ For any type of services Telecoms can act as enabler (eq. “support system”)
§ Shift focus away from network-centric service production model and customer view towards IT-toolchain-driven
service exposure differentiating on the experience level

15. PROGRAMMABLE TELECOMS – WHAT IS IN IT FOR TELCO’S?
§ A lot of relative margin on top of voice & SMS
§ The potential to assume a new role as communications infrastructure enabler
§ A chance to re-think NT/IT split and discover new ways to optimize organization and generate customer value
§ The ability to address new competitors in both global market as well as individual local markets
§ The Telco way towards CPaaS
§ Make or buy? Build or partner? Acquire? Aggregate?
§ The “enabler”/API story applies to many areas of Telecoms
§ Connectivity
§ Asset/inventory management
§ Business process integration and optimization
§ Automation, provisioning…

16. COMING BACK TO OUR AGENDA.
§ App development: I just want to make a call
§ Consuming APIs: It’s all fine as long as you know what you want and have done it before
§ App development vs. Telecom App development
§ What makes this discussion special?
§ The special role of Telecoms and the carrier ecosystem.
§ Once we treat Telecoms like “yet another IT application”, it all depends on how good the abstraction is, how
integrated the experience, and how good the ecosystem
§ And of course there’s scalability, regulation, automation, etc. but that should not be new to Telco’s
16

17. CONCLUSION
§ Find your way in what to focus on when exposing your assets and remaining a relevant service (not just connectivity)
provider – CPaaS should just be one part of your technology enabler strategy
§ Take fixed/mobile merger as blueprint for NT/IT mergers and merge/leverage capabilities similarly
§ Many new market players (e.g. CPaaS providers, aggregators) evolved that modern IT-supported Telco’s can take
head-on
§ And maybe one day…
§ App development: A call is just another API call.
§ You do not need to know details or have experiences, your library/SDK takes care of it all
§ Telecom App development = App development
