Software as a serviceSoftware as a service (SaaS) is a cloud computing service model in which a provider delivers application software to clients while managing the required physical and software resources. SaaS applications are accessed via either a web application or locally-installed software. Unlike other software delivery models, SaaS separates "the possession and ownership of software from its use".
Amazon (company)American multinational technology conglomerateAmazon.com, Inc. (doing business asAmazon) is an American multinational technology conglomerate engaged in e-commerce, cloud computing, online advertising, digital streaming, entertainment, and artificial intelligence.
Amazon Elastic Compute CloudCloud computing platform Amazon Elastic Compute Cloud (EC2) is a part of Amazon's cloud-computing platform, Amazon Web Services (AWS), that allows users to rent virtual computers on which to run their own computer applications. EC2 encourages scalable deployment of applications by providing a web service through which a user can boot an Amazon Machine Image (AMI) to configure a virtual machine, which Amazon calls an "instance", containing any software desired.
Cloud computingCloud computing is defined by the International Organization for Standardization (ISO) as "a paradigm for enabling network access to a scalable and elastic pool of shareable physical or virtual resources with self-service provisioning and administration on demand". It is commonly referred to as "the cloud". CharacteristicsIn 2011, the National Institute of Standards and Technology (NIST) identified five "essential characteristics" for cloud systems.
Programming toolA programming tool or software development tool is a computer program that is used to develop another computer program, usually by helping the developer manage computer files. For example, a programmer may use a tool called a to edit source code files, and then a compiler to convert the source code into machine code files. They may also use build automation tools that automatically package executable program and data files into shareable packages or install kits.
Web serviceA web service (WS) is either: a service offered by an electronic device to another electronic device, communicating with each other via the Internet, ora server running on a computer device, listening for requests at a particular port over a network, serving web documents (HTML, JSON, XML, images).In a web service, a web technology such as HTTP is used for transferring machine-readable file formats such as XML and JSON.
Computing platformA computing platform, digital platform, or software platform is the infrastructure on which software is executed. While the individual components of a computing platform may be obfuscated under layers of abstraction, the summation of the required components comprise the computing platform.
Server farmA server farm or server cluster is a collection of computer servers, usually maintained by an organization to supply server functionality far beyond the capability of a single machine. They often consist of thousands of computers which require a large amount of power to run and to keep cool. At the optimum performance level, a server farm has enormous financial and environmental costs.
MiddlewareMiddleware is a type of computer software program that provides services to software applications beyond those available from the operating system. It can be described as "software glue". Middleware makes it easier for software developers to implement communication and input/output, so they can focus on the specific purpose of their application.
Internet of thingsInternet of things (IoT) describes physical objects that are embedded with sensors, processing ability, software, and other technologies that connect and exchange data with other devices and systems over the Internet or other communication networks. The field of IoT encompasses electronics, communication, and computer science engineering.
APIAn application programming interface (API) is a connection between computers or between computer programs. It is a type of software interface, offering a service to other pieces of software. A document or standard that describes how to build such a connection or interface is called an API specification. A computer system that meets this standard is said to implement or expose an API. The term API may refer either to the specification or to the implementation.Elasticity (computing)In computing, elasticity is defined as "the degree to which a system is able to adapt to workload changes by provisioning and de-provisioning resources in an autonomic manner, such that at each point in time the available resources match the current demand as closely as possible". Elasticity is a defining characteristic that differentiates cloud computing from previously proposed distributed computing paradigms, such as grid computing.*As an Amazon Associate I earn from qualifying purchases.
