5 Horizontal clustering. 6 Vertical clustering. Hybrid clustering This involves a combination of both horizontal and vertical clus- tering. This is one of the robust configurations because it provides more reliable failover options. In all clustering options, a cluster manager is responsible for cluster-wide activities such as cluster-wide cache replication, session replication, failover support, and node monitoring. 1 Hyperscale architecture Hyperscale architecture supports addition and provision of additional computing nodes and other infrastructure components to the existing infrastructure, to scale to the high demands.

When to apply this pattern? À SOA is preferred choice for enterprise integration with internal and external systems. For most of the enterprise integrations, it is preferred to use a lightweight services integration. À Most popular usage of service is in the form of SOAP/REST based web services used in web architecture. All utility modules which are needed by external or 3rd party systems can be exposed as web services. À In some instances legacy and ERP systems also provide service interface as an integration option with enterprise applications.

Use REST architecture, which supports stateless invocation. REST-based services can be employed for integration with upstream systems. If session creation is inevitable, minimize the state information stored in the session. This helps the application server in optimal session state replication across cluster nodes. Reduce session stickiness, which helps load balancers to distribute the load more efficiently and improves seamless horizontal scaling. How it achieves scalability? ● ● ● ● If the application is stateless, load balancers can easily distribute the load without bothering with session stickiness.
