Cloud computing, often referred to as simply “the cloud,” is the delivery of on-demand computing resources—everything from applications to data centers—over the Internet on a pay-as-you-go i.e. rental basis.
- Flexible resources—Scale up or down quickly and easily to meet fluctuating demand
- only pay for what you use on a monthly basis
- Managed or sometimes Self service IT resources you need, when you need them
Cloud services are hosted on remote servers in a datacentre - generally owned and managed by others - the Service Provider. 3Rs has some facilities of its own but also partners with selected service providers to offer a solution to suit all levels of customer.
Cloud services now include voice i.e. telephony. Hosted voice solutions work on the same principal - pay an affordable, flexible monthly rental per user and get enterprise level capabilities that you could never have with an on-premise pbx hardware solution. From one man band to large call centre, hosted voice provides a Unified Comminications solution for the 21st Century business.
Software as a service (SaaS)
Cloud-based applications—or software as a service—run on remote computers “in the cloud” that are owned and operated by others and that connect to users’ computers via the Internet.
The benefits of SaaS
- You can sign up quickly and start using standard business applications
- Apps and data are accessible from any connected computer
- No data is lost if your computer breaks, as data is in the cloud
- The service is able to dynamically scale to your needs
With SaaS, you no longer need to buy, install, maintain or update software or licences - you will always have access to the latest versions with your monthly rental.
Public clouds are owned and operated by companies that offer rapid access over a public network to affordable computing resources. With public cloud services, users don’t need to purchase hardware, software, or supporting infrastructure, which is owned and managed by providers.
A private cloud is infrastructure operated solely for a single organization, whether managed internally or by a third party, and hosted either internally or externally. Private clouds can take advantage of cloud’s efficiencies, while providing more control of resources and steering clear of shared public resources.
A hybrid cloud uses a private cloud foundation combined with integration and use of public cloud services. A private cloud can’t exist in isolation from the rest of a company’s IT resources and the public cloud. Most companies with private clouds will manage workloads across data centers, private clouds, and public clouds creating hybrid clouds.
