Part III

Logical Design

A logical architecture identifies the components of a Directory Server Enterprise Edition deployment, and shows interrelationships between the components. Typically, use cases developed during the technical requirements phase indicate which components the deployment requires. However, the required components can often be derived directly from the business requirements.

This part provides sample logical architectures that are based on typical Directory Server Enterprise Edition deployment scenarios. The information in this part flows from a basic, single-server deployment to more complex deployments that span multiple data centers. The architectures discussed in the later chapters of this part build on the simpler architectures discussed in the earlier chapters.

This part includes the following chapters:

• Chapter 9, "Designing a Basic Deployment" describes a basic Directory Server Enterprise Edition deployment.

• Chapter 10, "Designing a Scaled Deployment" describes a deployment scaled to meet additional service requirements.

• Chapter 11, "Designing a Global Deployment" covers deployment considerations for deployments across multiple data centers.

• Chapter 12, "Designing a Highly Available Deployment" describes deployments designed to meet availability requirements.
