Topology and Communication General Concepts

Before you configure your Apache Geode members, make sure you understand the options for topology and communication.

  • Topology Types

    The Apache Geode topology options allow you to scale horizontally and vertically.

  • Planning Topology and Communication

    Create a topology plan and a detailed list of machines and communication ports that your members will use. Configure your Apache Geode systems and the communication between systems.

  • How Member Discovery Works

    Apache Geode provides various options for member discovery within a distributed system and between clients and servers.

  • How Communication Works

    Geode uses a combination of TCP and UDP unicast and multicast for communication between members. You can change the default behavior to optimize communication for your system.

  • Using Bind Addresses

    You use a bind address configuration to send network traffic through non-default network cards and to distribute the load of network traffic for Geode across multiple cards. If no bind address setting is found, Geode uses the host machine’s default address.

  • Choosing Between IPv4 and IPv6

    By default, Apache Geode uses Internet Protocol version 4 for Geode address specifications. You can switch to Internet Protocol version 6 if all your machines support it. You may lose performance, so you need to understand the costs of making the switch.
