SNA-shared nothing Architecture

Introduction:

Shared nothing Architecture

(No shared architecture) is a distributed architecture with each node independent. Typical SNA

The system centrally stores status information, such as the memory cache in the database.

Is not saved on the node.

 

For

Cluster.

The session Status of each node is stored on each node.

Replication will greatly affect performance. If SNA is used

To keep each node stateless and stop using sessions.

To maintain the global state, but to set the session

Directly in the database, add a distributed cache before the database

(Memcached is recommended.

). This will greatly improve the performance when the session is changed.

To the cache.

And database.
