Service Availability Forum
The Service Availability Forum (SAF or SA Forum) is a consortium that develops, publishes, educates on and promotes open specifications for carrier-grade and mission-critical systems. Formed in 2001, it promotes development and deployment of commercial off-the-shelf (COTS) technology. Description Service availability is an extension of high availability, referring to services that are available regardless of hardware, software or user fault and importance. Key principles of service availability: * Redundancy – "backup" capability in case of need to failover due to a fault * Stateful and seamless recovery from failures * Minimization of mean time to repair (MTTR) – time to restore service after an outage * Fault prediction & avoidance – take action before something fails The traditional definitions of high availability have their roots in hardware systems where redundancy of equipment was the primary mechanism for achieving uptime over a specific period. As software has co ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Private Company
A privately held company (or simply a private company) is a company whose Stock, shares and related rights or obligations are not offered for public subscription or publicly negotiated in their respective listed markets. Instead, the Private equity, company's stock is offered, owned, traded or exchanged privately, also known as "over-the-counter (finance), over-the-counter". Related terms are unlisted organisation, unquoted company and private equity. Private companies are often less well-known than their public company, publicly traded counterparts but still have major importance in the world's economy. For example, in 2008, the 441 list of largest private non-governmental companies by revenue, largest private companies in the United States accounted for $1.8 trillion in revenues and employed 6.2 million people, according to ''Forbes''. In general, all companies that are not owned by the government are classified as private enterprises. This definition encompasses both publ ...

The Linux Foundation
''The'' is a grammatical article in English, denoting nouns that are already or about to be mentioned, under discussion, implied or otherwise presumed familiar to listeners, readers, or speakers. It is the definite article in English. ''The'' is the most frequently used word in the English language; studies and analyses of texts have found it to account for seven percent of all printed English-language words. It is derived from gendered articles in Old English which combined in Middle English and now has a single form used with nouns of any gender. The word can be used with both singular and plural nouns, and with a noun that starts with any letter. This is different from many other languages, which have different forms of the definite article for different genders or numbers. Pronunciation In most dialects, "the" is pronounced as (with the voiced dental fricative followed by a schwa) when followed by a consonant sound, and as (homophone of the archaic pronoun ''thee' ...

Commercial Off-the-shelf
Commercial-off-the-shelf or commercially available off-the-shelf (COTS) products are packaged or canned (ready-made) hardware or software, which are adapted aftermarket to the needs of the purchasing organization, rather than the commissioning of custom-made, or bespoke, solutions. A related term, Mil-COTS, refers to COTS products for use by the U.S. and Canadian militaries. In the context of the Federal government of the United States, U.S. government, the Federal Acquisition Regulation (FAR) has defined "COTS" as a formal term for commercial items, including services, available in the commercial marketplace that can be bought and used under government contract. For example, Microsoft is a COTS software provider. Goods and construction materials may qualify as COTS but bulk cargo does not. Services associated with the commercial items may also qualify as COTS, including installation services, training services, and cloud services. COTS purchases are alternatives to custom softwa ...

High Availability
High availability (HA) is a characteristic of a system that aims to ensure an agreed level of operational performance, usually uptime, for a higher than normal period. There is now more dependence on these systems as a result of modernization. For example, to carry out their regular daily tasks, hospitals and data centers need their systems to be highly available. Availability refers to the ability of the user to access a service or system, whether to submit new work, update or modify existing work, or retrieve the results of previous work. If a user cannot access the system, it is considered ''unavailable from the user's perspective''. The term '' downtime'' is generally used to refer to describe periods when a system is unavailable. Resilience High availability is a property of network resilience, the ability to "provide and maintain an acceptable level of service in the face of faults and challenges to normal operation." Threats and challenges for services can range from ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hardware Platform Interface
The Hardware Platform Interface (HPI) is an open specification that defines an application programming interface (API) for platform management of computer systems.
