Site Reliability Engineering (SRE) is a subset of web development that uses elements of software engineering, IT infrastructure, and operations [1] to assist with reliability. SRE is similar to DevOps as both aim to improve the reliability and availability of systems.
[1] [2] To improve observability, software engineers use a wide range of logging and tracing techniques to gather telemetry information, and tools to analyze and use it. Observability is foundational to site reliability engineering, as it is the first step in triaging a service outage. One of the goals of observability is to minimize the amount ...
RAMP Simulation Software for Modelling Reliability, Availability and Maintainability (RAM) is a computer software application developed by WS Atkins specifically for the assessment of the reliability, availability, maintainability and productivity characteristics of complex systems that would otherwise prove too difficult, cost too much or take too long to study analytically.
2.0 Overview of Software Reliability Growth (Estimation) Models Software reliability growth (or estimation) models use failure data from testing to forecast the failure rate or MTBF into the future. The models depend on the assumptions about the fault rate during testing which can either be increasing, peaking, decreasing or some combination of ...
Reliability engineering is a sub-discipline of systems engineering that emphasizes the ability of equipment to function without failure. Reliability is defined as the probability that a product, system, or service will perform its intended function adequately for a specified period of time, OR will operate in a defined environment without failure.

Measuring a website's availability and reliability under various amounts of traffic is often referred to as load testing. Website monitoring also helps benchmark the website against the performance of a competitor to help determine how well a site is performing. Website speed is also used as a metric for search engine rankings. [2]
A variation, of this tool, is currently employed for the qualification of the modern day version known as OPENABAL. 2003 – Amazon. While working to improve website reliability at Amazon, Jesse Robbins created "Game day", [5] an initiative that increases reliability by purposefully creating major failures on a regular basis. Robbins has said ...
SAPHIRE is a probabilistic risk and reliability assessment software tool. SAPHIRE stands for Systems Analysis Programs for Hands-on Integrated Reliability Evaluations.The system was developed for the U.S. Nuclear Regulatory Commission (NRC) by the Idaho National Laboratory.
