TLDR
In today’s 24×7 environments that are running mission critical applications, businesses rely heavily on the availability of their data and often rely on redundant hardware to provide fault tolerance.Abstract:
In today’s 24×7 environments that are running mission-critical applications, businesses rely heavily on the availability of their data. Although servers and their software are generally reliable, there is always the risk of a hardware failure or a software bug, each of which could bring a server down. To mitigate these risks, business-critical applications often rely on redundant hardware to provide fault tolerance. If the primary system fails, then the application can automatically fail over to the redundant system. This is the underlying principle of high availability (HA).read more

Optimal design of resilient virtual networks [Invited]
TL;DR: This invited paper proposes novel resilient virtual network design models for flexible and cost-efficient virtual networks having resilience either at the virtual or the physical layer, or using a combination of both, and analyses the performance of the proposed resilience alternatives both via analysis and extensive simulations.
Evaluation and Analysis of Hardware Sizing for a Mission Critical Enterprise Application
TL;DR: The purpose of this document is to perform a complete sizing exercise based on the requirements for a mission critical business application and then translate them into an appropriate hardware configuration to give an as vendor neutral view as possible.
Disaster Recovery Framework for Commercial Banks in
TL;DR: In this article, the authors focused on disaster recovery practices in commercial banks in Sri Lanka and concluded that commercial banks only have ad-hoc disaster recovery standards and practices, as there is no standard framework available.

High-Availability Clusters A Taxonomy, Review, and Future Directions
TL;DR: In this paper, the authors present the architecture of high availability clusters (HACs) and propose a taxonomy that covers all key aspects of HACs, including deployment patterns, application areas, types of cluster, topology, cluster management, failure detection and recovery, consistency and integrity, and data synchronisation.
