Architecture: Kafka Active-Active with Confluent Bidirectional Cluster Linking

Your Confluent Cluster Linking DR setup is solid. Two clusters, one link, replication lag under five seconds. Then your platform team asks a reasonable question: the DR cluster is sitting idle, your producers in the secondary region are paying cross-regional latency on every write, and a failover still involves a manual promotion step. Can both clusters carry live traffic simultaneously? Can a regional outage become a non-event rather than an in… Read More

Architecture: Kafka

Every time you place an order, stream a video, or tap a payment terminal, dozens of systems need to know about it — simultaneously, reliably, in order. Getting data from where it's produced to where it needs to be processed, at scale, without losing anything, is one of the hardest problems in distributed systems. Apache Kafka was built specifically to solve it. Kafka is now the backbone of real-time data infrastructure at most large technolog… Read More

Or a website you could access at the office is suddenly blocked. Or your IT team says "it goes through Zscaler" when you ask why something is slow.
