System Design

Sybase Unwired Platform supports a variety of system design options to suit deployments ranging from a personal system on a single workstation to full-scale, clustered production systems.

Major factors that affect system design choices are:

Deployment scenario (personal system or enterprise system)
Balancing system cost and complexity, with scalability and performance
Desired Unwired Platform functionality and capabilities, some of which are limited to either clustered or non-clustered system designs

Note: Sybase Unwired Platform supports Online Data Proxy functionality only in a non-clustered system.

High-level design options fall into two categories:

Non-clustered systems
Clustered systems

Non-clustered Systems
In a non-clustered system, all Unwired Platform server components (the Unwired Server and data tier servers) are installed by a single installation procedure, on a single host.
Clustered Systems
In a clustered system, the Unwired Server components and data tier components are installed by separate installation procedures (possibly on the same host, but typically on separate hosts).
Single-node Designs
A non-clustered Unwired Platform system is a single-node system design.
Multi-node Designs
A clustered Unwired Platform system is a multi-node system design.
Multi-node with Shared Hosts
This multi-node design supports Unwired Servers colocated with data tier servers, on hosts configured with a failover cluster service.
Load Balancing
Load balancing can be applied to both client connections and EIS connections, to improve performance and enable efficient utilization of resources in the Unwired Server cluster.
