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.
Jim Scott is the director of enterprise strategy and architecture at MapR Technologies. He is passionate about building combined big data and blockchain solutions. Over his career, Jim has held positions running operations, engineering, architecture, and QA teams in the financial services, regulatory, digital advertising, IoT, manufacturing, healthcare, chemicals, and geographical management systems industries. Jim has built systems that handle more than 50 billion transactions per day, and his work with high-throughput computing at Dow Chemical was a precursor to more standardized big data concepts like Hadoop. Jim is also the cofounder of the Chicago Hadoop Users Group (CHUG).
