Cloud computing paradigm has ushered in the need to provide resources to users in a scalable, flexible, and transparent fashion much like any other utility. This has led to a need for developing evaluation techniques that can provide quantitative measures of reliability of a cloud computing system (CCS) for efficient planning and expansion. This paper presents a new, scalable algorithm based on non-sequential Monte Carlo Simulation (MCS) to evaluate large scale cloud computing system (CCS) reliability, and it develops appropriate performance measures. Also, a new iterative algorithm is proposed and developed that leverages the MCS method for the design of highly reliable and highly utilized CCSs. The combination of these two algorithms allows CCSs to be evaluated by providers and users alike, providing a new method for estimating the parameters of service level agreements (SLAs) and designing CCSs to match those contractual requirements posed in SLAs. Results demonstrate that the proposed methods are effective and applicable to systems at a large scale. Multiple insights are also provided into the nature of CCS reliability and CCS design.

“…This model can be used only for systems with periodic testing and continuous operation. The impact of various scenarios for restoring the processor after the occurrence of intermittent faults on its performance was assessed in [25]. To achieve this goal, the operation of a fault-tolerant multi-core processor is simulated in the presence of intermittent faults, subject to exponential and Weibull distribution.…”

Abstract:The cost of avionics maintenance is extremely high for modern aircraft. It can be as high as 30% of the aircraft maintenance cost. A great impact on the cost of avionics maintenance is provided by a high level of No Fault Found events (NFF). Intermittent faults are the leading cause of the NFF appearance in avionics. The NFF rate for avionics systems is between 20% and 50%. The practice of avionics operation and maintenance confirms the relevance of assessing the impact of intermittent faults on the maintenance cost and the choice of such option of the maintenance management, in which the negative impact of the intermittent faults is minimized. In this paper, a new mathematical model of digital avionics maintenance is developed. Key maintenance effectiveness indicators are selected. General mathematical expressions are obtained for the average availability, mean time between unscheduled removals (MTBUR), and expected maintenance cost of single unit and redundant avionics systems, which are subject to permanent failures and intermittent faults. The dependence of the maintenance effectiveness indicators on the rate of permanent failures and intermittent faults is investigated for the case of exponential distribution of time to failures and faults. The dependence of average availability on the number of spare units in the airline's warehouse is also analyzed. On the base of the proposed maintenance model, different options of avionics maintenance management are considered. Numerical examples illustrate how to reduce the expected maintenance cost of avionics systems.

“…Its drawbacks are it requires 90 B.3 Solutions for detection and diagnosis a long latency to discriminate, and infrastructure to detect and accumulate the respective faults. Other recent studies which also employ SAN with thresholds [136] applied to real systems only consider intermittent errors captured in state variables, which last more than one clock cycle.…”

"The problem with the world is that the intelligent people are full of doubts, while the stupid ones are full of confidence." Charles Bukowski AgraïmentsVolguera començar agraïnt totes aquelles persones que han fet possible que esta tesi esdevinguera realitat. A totes aquelles persones i que m'han acompanyat durant tot este temps, amb el seu suport tècnic, lingüístic, físic, econòmic o psicològic. Primerament, agrair els meus directors els doctors David de Andrés i Juan CarlosRuiz per la seua dedicació, suport i ànim durant estos anys. Heu sigut de gran ajuda. També al professor Pedro Gil per confiar en mi i donar-me el recolzament econòmic i científic per portar a terme el projecte.Així mateix, també volguera tenir unes paraules per als meus companys del grup de Sistemes Tolerants a Fallades (STF) i en especial als del laboratori: el ja doctor Jesus Friginal, Miquel Martinez, Héctor Marco, Javier Cancio i Antonio Bustos. Haveu sigut els millors, i junts hem passat molt bons moments. També agrair els companys de l'estada a Edinburgh Félix Casado i Ali Ebrahim, i molt especialment als del Barcelona Supercomputing Center Carles, Jaume, Mikel, Javi, Maria, David, Roberto, Milos, Mladen, Suzanna, Quixiao, Leonidas i la resta del grup CAOS per fer-me sentir com a casa.Per descomptat que no només he rebut suport dels companys de recerca. Per això he d'esmentar la meua estimada Sara, per donar-me tot el suport i l'estima possibles i impossibles, i els meus pares i germans, perquè sempre han estat fentme costat i m'han animat a seguir estudiant per comprendre millor el món que ens envolta.Finalment a les persones de la Universitat en general, i del món científic en particular, a la vocació dels quals devem que el sistema continue funcionant.Jaume.v SumariLa rellevància que l'electrònica adquireix en la seguretat dels productes ha crescut inexorablement, puix cada volta més aquesta abasta una major influència en la funcionalitat dels mateixos. Però, per descomptat, aquest fet ve acompanyat d'un constant necessitat de majors prestacions per acomplir els requeriments funcionals, mentre es mantenen els costos i consums en uns nivells reduïts. Donat aquest escenari, la indústria està fent esforços per proveir una tecnologia que complisca amb totes les especificacions de potència, consum i preu, tot a costa d'un increment en la vulnerabilitat a diversos tipus de fallades conegudes, i a la introducció de nous tipus.Per oferir una solució a les noves i creixents fallades als sistemes, els dissenyadors han recorregut a tècniques tradicionalment associades a sistemes crítics per a la seguretat, que en general oferixen resultats sub-òptims. De fet, les arquitectures empotrades modernes oferixen la possibilitat d'optimitzar les propietats de confiabilitat en habilitar la interacció dels nivells de hardware, firmware i software en el procés. Tot i això eixe punt no està resolt encara. Es necessiten avanços a tots els nivells en l'esmentada direcció per poder assolir els objectius d'una tolerància a fallades flexible, robusta, resili...
