How to migrate AWS MSK to Express Brokers with Lenses K2K Replicator

Aug 24, 2025 By Ivan Majnarić In Lenses
AWS MSK has become popular because it deploys Kafka easily and bills alongside other AWS services. Over the past few years, AWS announced Express Brokers, a new cluster type that offers unlimited storage and separates brokers from storage resources. This simplifies scaling and reduces the time needed to rebalance topics when adding or removing brokers.

Jun 23, 2025 By Andrew Stevenson In Lenses

The conference had an unusual dose of pragmatism, skepticism, and – dare we say it – common sense.

During a London meetup, we explored why this happens, what existing solutions offer, and why we decided to build our own Kafka replicator. Here's what we learned.
