Deployment Modes

You can deploy in the following ways:
  • Client-server deployment, also known as the leeches-seeders deployment.
  • Shared-all persistence
  • Shared-nothing persistence
  • Host-aware replication
  • Remote client
  • Cross-site replication
  • Clients (Leeches) and Servers (Seeders)
    When a member joins a space, it can join as a server (seeder) or as a client (leech).
  • Shared-All Persistence
    In ActiveSpaces, you can persist data to disk storage and recover it if data loss occurs or if there is a problem with the cluster startup.
  • Shared-Nothing Persistence
    With shared-nothing persistence, each node that joins a space as a seeder maintains a copy of the space data on disk. Each node that joins as a seeder writes its data to disk and reads the data when needed for recovery and for cache misses.
  • Host-Aware Replication
    Use host-aware replication to ensure that the data for seeders running on the same machine is always replicated by seeders running on a different machine.
  • Remote Client Architecture
    In some situations, where nodes are unable to become full peers in the data grid, for example, when there is a firewall protecting a LAN, you can deploy ActiveSpaces nodes as remote clients. Remote clients can perform puts and gets, but cannot act as seeders or assume a management role in the core cluster.
  • Cross-site Replication
    Cross-site replication is used to dynamically backup changes to the data in your metaspace to another metaspace in a different geographical location.
