System Center Opalis Integration Server 6.3 Unleashed: Architectural Design
When determining the best approach to deploy Opalis Integration Server (OIS), there are several factors to consider as you design an OIS instance. Before designing your instance, you should answer a number of questions about your environment, including network, domain structure, and location of your automation targets.
This chapter expands on the basic OIS architecture from Chapter 2, "Inside Opalis Integration Server 6.3," and explains how the components interact with one another during policy execution. It also discusses the major deployment models and identifies where each model would be most beneficial. In addition to architecture, this chapter reviews how the various security models affect an OIS deployment. You can use OIS in a wide range of environments and security models, from small networks to managed service providers. Each presents different challenges and requires different solutions.
Chapter 2 discussed the OIS components and explained their purpose. This chapter examines those same components as they work together to create, check-in, and execute policies. Because the policy is the core element of all automation, orchestration, and integration, this chapter looks into the lifecycle of a policy and examines how the OIS components support the phases of that lifecycle. Figure 3.1 shows the main components of OIS.
