| + | ==== ESB - Enterprise service bus ==== | ||
| + | {{tanszek:oktatas:informatikai_rendszerek_epitese:esb.png|ESB}} | ||
| + | |||
| + | Service BUS: Service Oriented Architecture (SOA). It is based on loosely coupled components (services). Analogy of the BUS concept known in networks. | ||
| + | |||
| + | **Main functions**: | ||
| + | |||
| + | * Message forwarding - Message Routing between services | ||
| + | * Service discovery | ||
| + | * Support conversion of different protocols | ||
| + | * Validation - schema validation | ||
| + | * Version management of services | ||
| + | * Monitoring services | ||
| + | * Business process management | ||
| + | |||
| + | **Advantages:** | ||
| + | |||
| + | * easily scalable use - from local service to full enterprise access | ||
| + | * instead of implementing (coding) the integration, creating configurations | ||
| + | * services can be easily started and stopped due to loose connection | ||
| + | |||
| + | **Disadvantages:** | ||
| + | |||
| + | * slow communication | ||
| + | * due to centralization, a complete shutdown may occur in the event of an error | ||
| + | * high complexity in configuration | ||
| + | |||
| + | Known implementations: | ||
| + | |||
| + | Azure Service Bus, Microsoft Biztalk Server, Mule ESB, Oracle ESB, IBM Websphere ESB, JBOSS ESB | ||
