The document discusses scaling limitations of containerized applications and proposes using a data grid approach with eventual consistency to address these limitations. It describes how current replication approaches do not scale well due to high memory and network usage from fully replicating data across all nodes. A data grid partitions data across nodes and allows asynchronous, eventually consistent replication to improve scalability and performance at the cost of strict consistency. The data grid model is better suited for high availability applications with uncontrolled loads that require high availability over consistency.
