Virtual Private Cloud
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 (denoted as ''users'' hereafter) using the resources. The isolation between one VPC user and all other users of the same cloud (other VPC users as well as other public cloud users) is achieved normally through allocation of a private IP subnet and a virtual communication construct (such as a VLAN or a set of encrypted communication channels) per user. In a VPC, the previously described mechanism, providing isolation within the cloud, is accompanied with a virtual private network (VPN) function (again, allocated per VPC user) 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' ...

Amazon Virtual Private Cloud
Amazon Virtual Private Cloud (VPC) is a commercial cloud computing service that provides a virtual private cloud, by provisioning a logically isolated section of Amazon Web Services (AWS) Cloud. Enterprise customers can access the Amazon Elastic Compute Cloud (EC2) over an IPsec based virtual private network. Unlike traditional EC2 instances which are allocated internal and external IP numbers by Amazon, the customer can assign IP numbers of their choosing from one or more subnets. Comparison to private clouds Amazon Virtual Private Cloud aims to provide a service similar to private clouds using technology such as OpenStack or HPE Helion Eucalyptus. However, private clouds typically use technology such as OpenShift application hosting and various database systems. Cloud security experts warn that there can be compliance risks, such as a loss of control or service cancellation in using public resources that do not exist with in-house systems. If transaction records are req ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Identity Management
Identity and access management (IAM or IdAM) or Identity management (IdM), is a framework of policies and technologies to ensure that the right users (that are part of the ecosystem connected to or within an enterprise) have the appropriate access to technology resources. IAM systems fall under the overarching umbrellas of IT security and data management. Identity and access management systems not only identify, authenticate, and control access for individuals who will be utilizing IT resources but also the hardware and applications employees need to access. The terms "identity management" (IdM) and "identity and access management" are used interchangeably in the area of identity access management. Identity-management systems, products, applications and platforms manage identifying and ancillary data about entities that include individuals, computer-related hardware, and software applications. IdM covers issues such as how users gain an identity, the roles, and sometimes the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
VCloud
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. In Q2 2017, VMware sold vCloud Air to French cloud service provider OVH. History VMware announced the vCloud initiative at the 2008 VMworld conference in Las Vegas and garnered significant press attention. At the 2009 VMworld conference in San Francisco vCloud was featured in the vCloud Pavilion. vCloud was also a subject at the 2010 VMworld conference. On May 21, 2013, the early access program for vCloud Hybrid Service was launched. On August 26, 2013, general availability was announced for vCloud Hybrid Service including features such as DRaaS and Direct Connect. vCloud Hybrid Service was rebranded to vCloud Air on August 21, 2014. vCloud Air provides a hybrid cloud� ...

Cloud Computing
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 International Organization for Standardization, ISO. Essential characteristics In 2011, the National Institute of Standards and Technology (NIST) identified five "essential characteristics" for cloud systems. Below are the exact definitions according to NIST: * On-demand self-service: "A consumer can unilaterally provision computing capabilities, such as server time and network storage, as needed automatically without requiring human interaction with each service provider." * Broad network access: "Capabilities are available over the network and accessed through standard mechanisms that promote use by heterogeneous thin or thick client platforms (e.g., mobile phones, tablets, laptops, and workstations)." * Pooling (resource management), Resource pooling: " The provider' ...

Microsoft Azure
Microsoft Azure, or just Azure ( /ˈæʒər, ˈeɪʒər/ ''AZH-ər, AY-zhər'', UK also /ˈæzjʊər, ˈeɪzjʊər/ ''AZ-ure, AY-zure''), is the cloud computing platform developed by Microsoft. It has management, access and development of applications and services to individuals, companies, and governments through its global infrastructure.

Data Center
A data center is a building, a dedicated space within a building, or a group of buildings used to house computer systems and associated components, such as telecommunications and storage systems. Since IT operations are crucial for business continuity, it generally includes redundant or backup components and infrastructure for power supply, data communication connections, environmental controls (e.g., air conditioning, fire suppression), and various security devices. A large data center is an industrial-scale operation using as much electricity as a medium town. Estimated global data center electricity consumption in 2022 was 240–340 TWh, or roughly 1–1.3% of global electricity demand. This excludes energy used for cryptocurrency mining, which was estimated to be around 110 TWh in 2022, or another 0.4% of global electricity demand. The IEA projects that data center electric use could double between 2022 and 2026. High demand for electricity from data centers, incl ...

Managed Services
Managed services is the practice of outsourcing the responsibility for maintaining, and anticipating need for, a range of processes and functions, ostensibly for the purpose of improved operations and reduced budgetary expenditures through the reduction of directly-employed staff. It is an alternative to the break/fix or on-demand outsourcing model where the service provider performs on-demand services and bills the customer only for the work done. The external organization is referred to as a managed service(s) provider (MSP). Definitions A managed IT services provider is a third-party service provider that proactively monitors & manages a customer's server/network/system infrastructure, cybersecurity and end-user systems against a clearly defined Service Level Agreement (SLA). Small and medium-sized businesses (SMBs), nonprofits and government agencies hire MSPs to perform a defined set of day-to-day management services so they can focus on improving their services witho ...
