The Kafka community faces a critical decision regarding the future of the project as it considers three competing KIPs aimed at reducing high replication costs across cloud availability zones while integrating object storage. The article explores two main approaches: a revolutionary path that embraces a direct-to-S3 architecture for greater elasticity and an evolutionary path that adapts existing components to reduce immediate refactoring needs. Ultimately, the choice made will shape the direction of Kafka for the next decade.

Choosing between single-tenant and multi-tenant architectures in Grafana Cloud involves weighing the benefits of simplicity and centralized management against the need for data isolation and customization. A single-stack approach is generally recommended for operational efficiency, while multiple stacks may be better for organizations requiring strict data segregation and compliance. Understanding the trade-offs can help organizations select the best architectural model for their needs.
