Infrastructure As a Service (IaaS)

An instant computing infrastructure, provisioned and managed over the Internet. Quickly scale up and down with demand, and pay only for what you use.

Public Cloud (6)

Computing services offered by third-party providers over the public Internet, making them available to anyone who wants to use or purchase them.

Amazon AWS Public Cloud
A subsidiary of Amazon.com that provides on-demand cloud computing platforms to individuals, companies and governments, on a paid subscription basis.
Amazon Web Services (AWS) is a subsidiary of Amazon.com that provides on-demand cloud computing platforms to individuals, companies and governments, on a paid subscription basis with a free-tier option available for 12 months. The technology allows subscribers to have at their disposal a full-fledged virtual cluster of computers, available all the time, through the internet. AWS's version of virtual computers have most of the attributes of a real computer including hardware (CPU(s) & GPU(s) for processing, local/RAM memory, hard-disk/SSD storage); a choice of operating systems; networking; and pre-loaded application software such as web servers, databases, CRM, etc. Each AWS system also virtualizes its console I/O (keyboard, display, and mouse), allowing AWS subscribers to connect to their AWS system using a modern browser. The browser acts as a window into the virtual computer, letting subscribers log-in, configure and use their virtual systems just as they would a real physical computer. They can choose to deploy their AWS systems to provide internet-based services for their own and their customers' benefit.

GCE users need to get authenticated based on OAuth 2.0 before launching the VMs. Google Compute Engine can be accessed via the Developer Console, RESTful API or Command Line Interface.

HP Cloud
A set of cloud computing services available from Hewlett-Packard (HP) that offered public cloud, private cloud, hybrid cloud, managed private cloud.
HP Cloud was a set of cloud computing services available from Hewlett-Packard (HP) that offered public cloud, private cloud, hybrid cloud, managed private cloud, and other cloud services. It was the combination of the previous HP Converged Cloud business unit and HP Cloud Services, which is the OpenStack technology-based public cloud. It is used by enterprise organizations so they can combine public cloud services with their own internal IT resources to create hybrid clouds, or a mix of different cloud computing environments made up of private and public clouds.

Private Cloud (5)

Computing services offered either over the Internet or a private internal network and only to select users instead of the general public.

OpenStack
A free and open-source software platform for cloud computing, mostly deployed as an IaaS.
OpenStack is a free and open-source software platform for cloud computing, mostly deployed as an infrastructure-as-a-service (IaaS). The software platform consists of interrelated components that control diverse, multi-vendor hardware pools of processing, storage, and networking resources throughout a data center. Users either manage it through a web-based dashboard, through command-line tools, or through a RESTful API. OpenStack.org released it under the terms of the Apache License.

Apache CloudStack
Open-source cloud computing software for creating, managing, and deploying infrastructure cloud services.
CloudStack is open-source cloud computing software for creating, managing, and deploying infrastructure cloud services. It uses existing hypervisors such as KVM, VMware ESXi|VMware vcenter and XenServer/XCP for virtualization. In addition to its own API, CloudStack also supports the Amazon Web Services (AWS) API and the Open Cloud Computing Interface from the Open Grid Forum.

VMware
Extension of its customer's existing vSphere installations, full compatibility with existing virtual machines virtualized with VMware software, tightly integrated networking.
VMware, Inc. is a subsidiary of Dell Technologies that provides cloud computing and platform virtualization software and services. It was the first commercially successful company to virtualize the x86 architecture.

VMware's desktop software runs on Microsoft Windows, Linux, and macOS, while its enterprise software hypervisor for servers, VMware ESXi, is a bare-metal hypervisor that runs directly on server hardware without requiring an additional underlying operating system.

In May 2013, VMware launched its own IaaS service, vCloud Hybrid Service, at its new Palo Alto headquarters (vCloud Hybrid Service now known as vCloud Air), announcing an early access program in a Las Vegas data center. The service is designed to function as an extension of its customer's existing vSphere installations, with full compatibility with existing virtual machines virtualized with VMware software and tightly integrated networking. The service is based on vCloud Director 5.1/vSphere 5.1.

Eucalyptus
Eucalyptus software’s main advantage is its AWS compatibility, based on a partnership with Amazon.
Eucalyptus released its first product in 2008. Nowadays the company provides its software as open source products and services. (Recently, Eucalyptus was bought by HP, a supporter of OpenStack.) From the company’s download area, you can install a private cloud on your computer. From its product area, you can contract servers for your private cloud.

Eucalyptus software’s main advantage is its AWS compatibility, based on a partnership with Amazon. So, some features that AWS makes available for the public cloud are applicable to Eucalyptus services.

Eucalyptus software’s weak points are the limited GUI and the risk of uncertainty generated by AWS’s private-cloud strategy: AWS offers Amazon Virtual Private Cloud and a connection to a hardware VPN (virtual private network).

Azure Stack
An on-premises version of Microsoft Azure public cloud.
Azure Stack is an on-premises version of its public cloud, could be important for networking and data center pros for one simple reason: It gives customers a way to use a popular and familiar cloud platform without shipping their sensitive data into a multi-tenant environment.

Google App Engine
A web framework and cloud computing platform for developing and hosting web applications in Google-managed data centers.
Google App Engine (often referred to as GAE or simply App Engine) is a web framework and cloud computing platform for developing and hosting web applications in Google-managed data centers. Applications are sandboxed and run across multiple servers. App Engine offers automatic scaling for web applications—as the number of requests increases for an application, App Engine automatically allocates more resources for the web application to handle the additional demand.

Google App Engine is free up to a certain level of consumed resources. Fees are charged for additional storage, bandwidth, or instance hours required by the application. It was first released as a preview version in April 2008 and came out of preview in September 2011.
