“…A comparative evaluation of two redundancy and proactive fault tolerance techniques was proposed in [50], based on the cloud providers' and consumers' requirements. This evaluation was proposed in terms of cloud environment's availability based on the consumers' viewpoint and cost of energy from the providers' viewpoint.…”

Reliability and high availability have always been a major concern in distributed systems. Providing highly available and reliable services in cloud computing is essential for maintaining customer confidence and satisfaction and preventing revenue losses. Although various solutions have been proposed for cloud availability and reliability, but there are no comprehensive studies that completely cover all different aspects in the problem. This paper presented a ‘Reference Roadmap’ of reliability and high availability in cloud computing environments. A big picture was proposed which was divided into four steps specifying through four pivotal questions starting with ‘Where?’, ‘Which?’, ‘When?’ and ‘How?’ keywords. The desirable result of having a highly available and reliable cloud system could be gained by answering these questions. Each step of this reference roadmap proposed a specific concern of a special portion of the issue. Two main research gaps were proposed by this reference roadmap.

“…Replication of tasks is a fault tolerance technique that applies redundancy. Sampaio and Barbosa [13] recently showed that the technique leads to increase of monetary costs since it implies the use of additional resources. Also Long et al [14] addressed the problem of SIs unreliability caused by the fluctuations of the bidding prices (i.e., SI may be terminated at any time when the bidding price is lower than the spot price).…”

Amazon Elastic Compute Cloud (EC2) gives access to resources in the form of instances. EC2 Spot Instances (SIs) offer spare compute capacity at steep discounts compared to reliable and fixed price on-demand instances. However, SIs are unreliable since they can be reclaimed by EC2 at any given time, with a two-minute interruption notice. In this paper, we propose a container migration-based solution to build reliable compute environments on top of unreliable EC2 instances. Our solution leverages recent findings on performance and behavior characteristics of EC2 SIs. We compare the performance of our algorithm to that of state-of-the-art algorithms, by running a real-life workflow application constrained by user-defined deadline and budget parameters. The results show that our solution is able to build reliable virtual compute environments on top of EC2 on-demand-, spot block, and SI purchasing models, and successfully conclude submitted workflow applications with budget and deadline constraints, for a worse-case scenario.

Trustworthy cloud computing has been a central tenet of the European Union cloud strategy for nearly a decade. This chapter discusses the origins of trustworthy computing and specifically how the goals of trustworthy computing—security and privacy, reliability, and business integrity—are represented in computer science research. We call for further inter- and multi-disciplinary research on trustworthy cloud computing that reflect a more holistic view of trust.
