Availability lies in the thought of multiple systems that are enhancing each others capabilities and data being location unaware...and zero dependencies. (Cloud enabled) On-line service providers are nowadays fully required to offer 24x7 services (users come from around the globe). More and more services are to be consolidated on the same infrastructures to enable cost saving.
As an IT Security Architect I am working on a daily basis to deal with the consequences of the above requirements
- Creation of services that are 24x7 available
- Managing the on-line risk profile for services and infrastructures to minimize opportunity for the launch of successful and feasible attacks
- Design services and infrastructures with consolidation in mind from the first draft
