How Geographic Redundancy Can increase provider Availability and Reliability of Computer-Based Systems
Enterprises make major investments in geographically redundant platforms to mitigate the most unlikely probability of a normal or man-made catastrophe rendering their fundamental website inaccessible or destroying it thoroughly. whereas geographic redundancy has seen advantages for catastrophe restoration, it's some distance much less noticeable what profit georedundancy deals for extra universal undefined, software program, and human disasters. Beyond Redundancy presents either a theoretical and sensible remedy of the possible and sure advantages from geographic redundancy for either provider availability and repair reliability.
The ebook is equipped into 3 sections:
Basics presents the required historical past on georedundancy and repair availability
Modeling and research of Redundancy supplies the technical and mathematical info of carrier availability modeling of georedundant configurations
Recommendations bargains particular tips on structure, necessities, layout, trying out, and research of georedundant configurations
A whole georedundant case research is integrated to demonstrate the options. The booklet considers either georedundant platforms and georedundant options. The textual content additionally presents a normal dialogue concerning the capital expense/operating price tradeoff that frames process redundancy and georedundancy. those additional gains make Beyond Redundancy a useful source for network/system planners, IS/IT body of workers, method architects, procedure engineers, builders, testers, and catastrophe recovery/business continuity specialists and planners.

2 THE EIGHT-INGREDIENT MODEL Information services are typically implemented via integrated suites of computer systems and networking infrastructure. In addition to networking infrastructure, the computer software and hardware require other supporting infrastructure to operate. The eight-ingredient model—described in Rauscher et al. â•‡ The eight-ingredient model. 1—gives a generic framework of the ingredients required for an information system to operate. The system itself consists of software that executes on hardware.
17 users affected) into a percentage of capacity that can prorate the outage duration. Normalization units for enterprise systems are either based on the number of systems in service, number of provisioned users, or number of active users. Normalizing outages based on systems can be somewhat misleading if systems have different configurations and/or user loads that can overstate outages on small, lightly loaded systems and understate outages on large, heavily loaded systems. Normalizing on the number of provisioned users can understate the apparent user impact, because although only a fraction of provisioned users may be online at any point an outage is significant to them.
