Chapter 8: Distributed Deployment at Runtime Multiple Instances of a Service or Process in a Domain After you establish a service or process in the production environment, you can deploy multiple instances of the service. This scales your service oriented architecture, as shown: Directory Service Management Node ctHostA1 ctHostB1 Advanced ESB Service BPEL Server + BPEL DataStore esbHostA1 ESB Container Sonic ESB esbHostB1 ctHostA1 HostA Management Container SonicMQ Enterprise Service Bus Advanced ESB Service BPEL Server + BPEL DataStore ESB Container Sonic ESB Management Container SonicMQ In this illustration, the service that was imported into the domain is duplicated by installing similar deployment software on a different host, and—when the components register in the Directory Service—adding an instance of the service to the new container. Both instances of the service provide identical operation. As you deploy more instances of the service, and the service is modified, one update to the domain perpetuates the change to every service instance automatically. 148 Progress Sonic ESB Deployment Guide 8.5 ctHostB1 HostB
Distributed Installation of a Product’s Runtime Features Distributed Installation of a Product’s Runtime Features my.xar Import ESB Artifacts You can locate the runtime features of some products on different systems. That means that you could deploy several instances of one runtime feature and a few of another. It also means that features that intensively use the resources of a host system can be isolated from other runtime features of its product deployment, as shown: Directory Service Management Node ctHostA1 ctHostB1 Advanced ESB Service Service One esbHostA1 ESB Container Sonic ESB esbHostB1 ctHostA1 HostA Management Container SonicMQ Enterprise Service Bus ctHostB1 HostB Advanced ESB Service Service Two ESB Container Sonic ESB Management Container SonicMQ In this illustration, a deployment archive imported into the Directory Service defines two fully-encapsulated services. The services could be distributed as follows: ● Service One— On system HostA, the SonicMQ management container, and ESB Container installations are registered in the Directory Service. Then, Service One is deployed into the ESB Container. ● Service 2— On system HostB, the SonicMQ management container, and ESB Container are registered in the Directory Service. Then, Service Two is deployed into that ESB Container. Progress Sonic ESB Deployment Guide 8.5 149
