Cloud Services
Cloud services means services made available to users on demand via the Internet from a cloud computing provider’s servers as opposed to being provided from a company’s own on-premises servers. Cloud services are designed to provide easy, scalable access to applications, resources and services, and are fully managed by a cloud services provider. A cloud service can dynamically scale to meet the needs of its users, and because the service provider supplies the hardware and software necessary for the service, there’s no need for a company to provision or deploy its own resources or allocate IT staff to manage the service.

So where does Office 365 fit into the cloud? Office 365 is Microsoft’s cloud-based package of apps and services that enables people to work flexibly from anywhere with technology that is easy to use. With Office 365, they get anywhere access to familiar Office tools, plus enterprise-grade email, conferencing, collaboration, and enterprise social capabilities.

And since all of these business-class services are hosted in Microsoft data centers, customers don’t need to worry about maintaining servers and applying updates; instead, businesses can focus on their core competency and leave the maintenance to Infratech.

Installed Versus Web-Based
Web based software is accessed through a connection to the cloud and can only be accessed using the computer it is installed on. All the plans are available both online and offline.

Microsoft Office Applications
Microsoft Office applications are a system of Microsoft productivity software that supports common business tasks, including word processing, email, presentations, and data management and analysis. This includes Word, Excel, PowerPoint, and Outlook.

Cloud Storage
Cloud Storage is a model of networked storage where data is stored in pools of storage that are virtualized from large data centers according to the requirements of the customer. Microsoft OneDrive is an online service that lets users access and share documents, photos, and other files from anywhere.
