Space-Based Architecture

is a distributed computing model that allows applications to be built and deployed across multiple nodes in a network. The nodes communicate using a shared memory space.

• Distributed computing model
• Applications deployed across multiple nodes
• The nodes communicate using a shared space
• It is composed of five components:
• Processing unit – the application logic and in-memory data grid
• Virtualized middleware – to coordinate the processing units
• Virtualized middleware – message, data, and processing grids. Deployment manager.
• Data pumps – send the data to a database (asynchronously) using Data Readers and Writers
• Pros: high scalability, high concurrency, elasticity
• Cons: – cost, testability, simplicity, deployability, modularity, fault tolerance
• Products: Hazelcast, Apache Ignite, Oracle Coherence, HAProxy, Nginx
