Understanding a typica l AEM deployment

1. Oak Architectures2. Typical AEM Environment3. Dispatcher Module Deployment 4. AEM Communities

3#evolverocks

Oak Architectures: Single TarMK instance

A single TarMK instance runs on a single server. Default setup for Author instances Advantages:

Simplicity Easy maintenance Good performance 

Disadvantages: Not scalable beyond the limits of the server capacity No failover capacity

4#evolverocks

Oak Architectures: TarMK Cold Standby

One TarMK instance acts as the primary instance. The repository from the primary is replicated to a standby failover system. The failover server is running in cold-standby mode, which means that the

HttpReceiver of the instance is running. Advantages:

Simplicity Easy maintenance Good performance Failover is provided 

Disadvantages: Not scalable beyond limits of the server capacity One server is idle

5#evolverocks

Oak Architectures: TarMK Farm Multiple Oak instances run with one TarMK instance each. The TarMK repositories are independent and need to be kept in sync. This is the default deployment for AEM Publish instances. Advantages:

Good performance Scalability for read access is provided Failover is provided 

Disadvantages: Write access kept in sync between instances
