NetApp, Inc. is an American data infrastructure company that provides unified data storage, integrated data services, and cloud operations (CloudOps) solutions to enterprise customers. The company is based in Cork City, Ireland. It has ranked in the Fortune 500 from 2012 to 2021. Founded in 1992 with an initial public offering in 1995, NetApp offers cloud data services for management of applications and data both online and physically.
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. A user can create, launch, and terminate server-instances as needed, paying by the second for active servers – hence the term "elastic". EC2 provides users with control over the geographical location of instances that allows for latency optimization and high levels of redundancy. In November 2010, Amazon switched its own retail website platform to EC2 and AWS.
Platform as a service (PaaS) or application platform as a service (aPaaS) or platform-based service is a cloud computing service model where users provision, instantiate, run and manage a modular bundle of a computing platform and applications, without the complexity of building and maintaining the infrastructure associated with developing and launching application(s), and to allow developers to create, develop, and package such software bundles.
vCloud Air was a public cloud computing service built on vSphere from VMware. vCloud Air has three "infrastructure as a service" (IaaS) subscription service types: dedicated cloud, virtual private cloud, and disaster recovery. vCloud Air also offers a pay-as-you-go service named Virtual Private Cloud OnDemand.
"Cloud computing is 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," according to ISO.
The Open Cloud Computing Interface (OCCI) is a set of specifications delivered through the Open Grid Forum, for cloud computing service providers. OCCI has a set of implementations that act as proofs of concept. It builds upon World Wide Web fundamentals by using the Representational State Transfer (REST) approach for interacting with services.
A virtual private cloud (VPC) is an on-demand configurable pool of shared resources allocated within a public cloud environment, providing a certain level of isolation between the different organizations using the resources. The isolation between one VPC user and all other users of the same cloud is achieved normally through allocation of a private IP subnet and a virtual communication construct per user. In a VPC, the previously described mechanism, providing isolation within the cloud, is accompanied with a virtual private network (VPN) function that secures, by means of authentication and encryption, the remote access of the organization to its VPC resources. With the introduction of the described isolation levels, an organization using this service is in effect working on a 'virtually private' cloud, and hence the name VPC.
AppScale is a software company that offers cloud infrastructure software and services to enterprises, government agencies, contractors, and third-party service providers. The company commercially supports one software product, AppScale ATS, a managed hybrid cloud infrastructure software platform that emulates the core AWS APIs. In 2019, the company ended commercial support for its open-source serverless computing platform AppScale GTS, but AppScale GTS source code remains freely available to the open-source community.
OVH, legally OVH Groupe SA, is a French cloud computing company which offers VPS, dedicated servers, and other web services. As of 2016 OVH owned the world's largest data center in surface area. As of 2019, it was the largest hosting provider in Europe, and the third largest in the world based on physical servers. According to W3Techs, OVH has 3.4% of website data center market share in 2024. The company was founded in 1999 by the Klaba family and is headquartered in Roubaix, France. In 2019 OVH adopted OVHcloud as its public brand name.
Cloud Foundry is an open source, multi-cloud application platform as a service (PaaS) governed by the Cloud Foundry Foundation, a 501(c)(6) organization.
A cloud database is a database that typically runs on a cloud computing platform and access to the database is provided as-a-service. There are two common deployment models: users can run databases on the cloud independently, using a virtual machine image, or they can purchase access to a database service, maintained by a cloud database provider. Of the databases available on the cloud, some are SQL-based and some use a NoSQL data model.
FUJITSU Cloud IaaS Trusted Public S5 is a Fujitsu cloud computing platform that aims to deliver standardized enterprise-class public cloud services globally. It offers Infrastructure-as-a-Service (IaaS) from Fujitsu's data centres to provide computing resources that can be employed on-demand and suited to customers needs.
OpenShift is a family of containerization software products developed by Red Hat. Its flagship product is the OpenShift Container Platform — a hybrid cloud platform as a service built around Linux containers orchestrated and managed by Kubernetes on a foundation of Red Hat Enterprise Linux. The family's other products provide this platform through different environments: OKD serves as the community-driven upstream, Several deployment methods are available including self-managed, cloud native under ROSA, ARO and RHOIC on AWS, Azure, and IBM Cloud respectively, OpenShift Online as software as a service, and OpenShift Dedicated as a managed service.
Abiquo Hybrid Cloud Management Platform is a web-based cloud computing software platform developed by Abiquo. Written entirely in Java, it is used to build, integrate and manage public and private clouds in homogeneous environments. Users can deploy and manage servers, storage system and network and virtual devices. It also supports LDAP integration.
Backend as a service (BaaS), sometimes also referred to as mobile backend as a service (MBaaS), is a service for providing web app and mobile app developers with a way to easily build a backend to their frontend applications. Features available include user management, push notifications, and integration with social networking services. These services are provided via the use of custom software development kits (SDKs) and application programming interfaces (APIs). BaaS is a relatively recent development in cloud computing, with most BaaS startups dating from 2011 or later. Some of the most popular service providers are AWS Amplify and Firebase.
HPE Helion was Hewlett-Packard's portfolio of open-source software and integrated systems for enterprise cloud computing. It was announced by HPE Cloud in May 2014. HPE Helion grew from under US$300 million to over US$3 billion by 2016. HP closed the public cloud business on 31 January 2016. HP has hybrid cloud and other offerings but the Helion public cloud offering was shut down.
BOSH is an open-source software project that offers a toolchain for release engineering, software deployment and application lifecycle management of large-scale distributed services. The toolchain is made up of a server and a command line tool. BOSH is typically used to package, deploy and manage cloud software. While BOSH was initially developed by VMware in 2010 to deploy Cloud Foundry PaaS, it can be used to deploy other software. BOSH is designed to manage the whole lifecycle of large distributed systems.
"Serverless computing is a cloud service category in which the customer can use different cloud capabilities types without the customer having to provision, deploy and manage either hardware or software resources, other than providing customer application code or providing customer data. Serverless computing represents a form of virtualized computing." according to ISO/IEC 22123-2 Function as a service and serverless database are two forms of serverless computing.
The concept of the cloud computing as a platform for distributed computing traces its roots back to 1993. At that time, Apple spin-off General Magic and AT&T utilized the term in the context of their Telescript and Personal Link technologies.
IBM Cloud is a set of cloud computing services for business offered by the information technology company IBM.
