Scalability

Scalability is the ability to respond to increasing numbers of users who access resources in the domain. ISAM uses several techniques to provide scalability. ISAM provides the following scalability methods:

• Replication of services
  • Authentication services
  • Authorization services
  • Security policies
  • Data encryption services
  • Audit services

• Front-end replicated servers
  • Mirrored resources for high availability
  • Load balancing client requests

• Back-end replicated servers
  • Back-end servers can be Security Verify Access WebSEAL or other application servers
  • Mirrored resources (unified object space) for high availability

  • Additional content and resources
  • Load balancing of incoming requests

• Optimized performance by allowing for the offloading of authentication services and authorization services to separate servers
• Scaled deployment of services without increasing management processor usage
