Real-time data streaming is a hot topic in the Telecommunications Industry / Telecom Sector. As telecommunications companies strive to offer high speed, integrated networks with reduced connection times, connect countless devices at reduced latency, and transform the digital experience worldwide, more and more companies are turning to Apache Kafka’s data stream processing solutions to deliver a scalable, real-time infrastructure for OSS and BSS scenarios. Enabling a combination of on-premise data centers, edge processing, and multi-cloud architectures is becoming the new normal in the Telco Industry. This combination is enabling accelerated growth from value-added services delivered over mobile networks. Join Kai Waehner, Technology Evangelist at Confluent, for this session which explores various telecommunications use cases, including data integration, infrastructure monitoring, data distribution, data processing and business applications. Different architectures and components from the Kafka ecosystem are also discussed. This talk explores: - Overcome challenges for building a modern hybrid telco infrastructure - Build a real time infrastructure to correlate relevant events - Connect thousands of devices, networks, infrastructures, and people - Work together with different companies, organisations and business models - Leverage open source and fully managed solutions from the Apache Kafka ecosystem, Confluent Platform and Confluent Cloud

Telcos’ current IT architectures are not able to satisfy
business needs because of their high complexity, lack of
flexibility and low level of automation.

Telco need to transform everything
“The biggest hurdle to
overcome with digital
transformation is to
understand that it isn’t just a
simple technology challenge
– it covers every part of the
telco business.”

The market development of the SMS
https://disruptive.asia/p2p-sms-2022-ovum/
https://dis-blog.thalesgroup.com/mobile/2014/10/06/three-issues-mobile-network-operators-must-face-to-reverse-the-slide-of-sms-revenue/
SMS has become a large commercial industry, earning $114.6 billion globally in 2010.
Costs between 10 cents to 20 cents per message were the normal in many countries.

7. Apache Kafka in the Telco Industry – @KaiWaehner - www.kai-waehner.de
OTT (Over The Top) - aka Telco-OTT
OTT Applications use the existing Telecommunication Infrastructure
and provide better cost / features / convenience.
Example: Messaging applications
• SMS (short message service) by telco providers: Text format message.
• WhatsApp (by Facebook): Above + group chat, gif/stickers, photos,
videos, audio, location, contact information and ‘walkie-talkie’ services.
• WeChat (by Tencent): Above + payment + various other partner
integrations
Options for the Telco provider:
• Partnership: No control + potentially damage their reputation and
customer relationships
• Development of own services: No skills + too late
• Blocking OTT services: Losing revenue for traffic and customers
The answer from the telco providers: RCS (rich communication services)…
What do you use today?

● ‘Payment’ transactions enter
from us-east and us-west with
fully synchronous replication
● ‘Log’ and ‘Location’ information
in the same cluster use async -
optimized for latency
● Automated disaster recovery
(zero downtime, zero data loss)
Result: Clearing time from ‘deposit’ to
‘available’ goes from 5 days to 5
seconds (including security checks)

32. Apache Kafka in the Telco Industry – @KaiWaehner - www.kai-waehner.de
Challenges
• Vendor-specific management
information base (MIB) result in
multiple, incompatible data semantics
and naming
• Vendor-specific EMS often required
resulting in inefficient “swivel-chair”
troubleshooting of issues.
• Realtime analytics across a
heterogenous environment becomes
impossible.
• Migration to modern streaming
technologies means even more
segmentation of visibility.

Supports real time stream processing
But also Fire-and-Forget, Publish / Subscribe, Request-Response / RPC, Batch, …
Single infrastructure
Messaging, storage, processing
Small and high throughputs (up to Gigabytes per second)
Elastic Scalability (up and down)
Reliability and zero downtime
High availability
Exactly-once semantics
Rolling upgrades and dynamic configuration changes
Backwards compatibility
Decoupling of clients
Agile microservices
Dumb pipes, smart endpoints
Handling backpressure
No vendor lock-in
