Description

Application developers and architects today are interested in making their applications as real-time as possible. To make an application respond to events as they happen, developers need a reliable way to move data as it is generated across different systems, one event at a time. In other words, these applications need messaging.

Messaging solutions have existed for a long time now, but in the age of Hadoop, newer solutions like Kafka are being introduced that have higher performance, more scalability, and better integration with the Hadoop ecosystem. Kafka and similar systems are based on drastically different assumptions than the legacy systems and have vastly different architectures. In light of this, can distributed messaging systems like Kafka be considered replacements for legacy technologies?

Jim Scott answers that question by delving into the architectural details and trade-offs of both legacy and new messaging solutions.

Topics include:

  • Queues versus logs
  • Security issues such as authentication, authorization, and encryption
  • Scalability and performance
  • Handling applications that span multiple data centers
  • Multitenancy considerations
  • APIs, integration points, and more
