2. Automated AWS Internal Workflow (Sharded Cluster)

WAP automatically completes the following sharded cluster deployment workflow within AWS:

  1. Config Server Replica Set Creation

    Automatically create a 3-node Config Server.

    Initialize the Config Server replica set.

    Store cluster metadata.

  2. Shard Replica Set Creation

    Create multiple replica sets based on the Shard Number.

    Each Shard independently completes EC2 provisioning, disk attachment, and MongoDB initialization.

    Automatically execute rs.initiate().

  3. Mongos Deployment

    Create the specified number of Mongos instances.

    Configure and connect Mongos to the Config Server.

  4. Shard Registration

    Automatically execute sh.addShard().

    Register all Shards with the sharded cluster.

  5. Authentication and Authorization Initialization

    Create a unified administrative user.

    Synchronize authentication configuration across Config Servers, Shards, and Mongos.

  6. Cluster Health Validation

    Validate the status of Shards, Config Servers, and Mongos.

    Verify replica set health and routing status.

  7. Platform Onboarding

    Onboard the cluster into the WAP unified monitoring and operations system.

    Enable alerting, backup, and scaling capabilities.

    Update the cluster status to Running.
