Durability ; Dependability ; Quality over time ; Availability to perform a function ; Components of Reliability. In your everyday life, that means the lights come on when you get home, the refrigerator is working and businesses continue to hum around the clock. In other words, availability is the probability that a system is not failed or undergoing a repair action when it needs to be used. Reliability. With the growing importance of these issues to IT and telecom managers, a little more rigour should be expected. Leonardo ENERGY presents a series of Application Notes on Availability, Resilience, Reliability and Redundancy, intended for design and maintenance engineers. What is the difference between work conserving I/O scheduler and non-work conserving I/O scheduler? Some use it to mean ability to reach consensus despite faults[2] (basically C in CAP). What are the trade-offs between costs, failures, reduced services and reduced performance? Answer from http://www.quora.com/Whats-the-difference-between-Reliability-Durability-and-Availability-for-data-storage-system. As said, loose coupling needs more effort on the application development side. In some cases, they do not provide correct definitions. June 30, 2008 By DatacenterDynamics Comment. Reliability becomes important when you have some long running process, let's say it's a cron job, it just takes two hours to complete. First consider definitions of each. What is Resiliency? Realistically, almost all modern systems and their clients are physically distributed, and the components are connected together by some form of network. In other words, Reliability can be considered a subset of Availability. Reliability is about designing, running and maintaining electricity supply to provide an adequate, safe and stable flow of electricity. Reliability vs. Reliability. The absolute values of availability required or It is most often expressed as a percentage, using the following calculation: Availability = 100 x (Available Time (hours) / Total Time (hours)) For equipment and/or systems that are expected to be able to be operated 24 hours per day, 7 days per week, Total Time is usually defined as being 24 hours/day, 7 days/week (in other words 8,760 hours per year). Durable vs Resilient - What's the difference? Resilience vs. Resiliency. Right? So what is all the fuss about those other terms? Reliability – What’s the Difference? Views: 652.

Reliability vs. resilience – What is the difference between reliability and resilience and why does it ... availability – and perhaps most significantly –resilience. This is not the simple issue of whether or not IP-based systems can be made as reliable as their predecessors. Availability comes in multiple forms. One type aims at maintaining full service and performance, and another type aims at failing gracefully by reducing services or performance. durable | resilient | As adjectives the difference between durable and resilient is that durable is able to resist wear, decay; lasting; enduring while resilient is able to endure tribulation without cracking. http://www.quora.com/Whats-the-difference-between-Reliability-Durability-and-Availability-for-data-storage-system, http://webdam.inria.fr/Jorge/html/wdmch15.html, http://www.cse.scu.edu/~jholliday/REL-EAR.htm, Data Consistency Models of Public Cloud Storage Services: Amazon S3, Google Cloud Storage and Windows Azure Storage, Large-scale Data Storage and Processing System in Datacenters. Reliability vs. For example, a network could block certain nodes or reduce the bandwidth available to all nodes. Availability is the percentage of time that something is operational and functional. Some people use “reliable” as a synonym for “available”. Some people use “reliable” as a synonym for “available”. Reliability vs validity: what’s the difference?

Reliability vs. Resiliency. As you can see, resilience is much more common and has been for at least 100 years. Resilience is very different. Availability refers to system uptime, i.e. Reliability is how well something endures a variety of real world conditions. If the chart included data from social science journals and other periodicals, perhaps resiliency would be more common yet.
