10 Reasons for Event Streaming with Apache Kafka
Real Time
Scalable
Cost Reduction
24/7 – Zero downtime, zero data loss
Decoupling – Storage, Domain-driven Design
Data (re-)processing and stateful client applications
Integration – Connectivity to IoT, legacy, big data, everything
Hybrid Architecture – On Premises, multi cloud, edge computing
Fully managed cloud
No vendor locking

Challenges:
● Proprietary forwarders that can only
send data to single source
● Data locked from being shared
● Difficult to scale with growing data

● Prohibitively high indexing costs
● Unable to filter out noisy data
● Slow batch processing

Kafka
Apps
Store Forever
Older data is offloaded to inexpensive object
storage, permitting it to be consumed at any time.
Save $$$
Storage limitations, like capacity and duration,
are effectively uncapped.
Instantaneously scale up and down
Your Kafka clusters will be able to automatically
self-balance load and hence elastically scale
