Computing is now a service. Something that you buy when you need it. In fact, everything is becoming a service, or service-orientated. For a long time, businesses have stated that they get frustrated by the complexity of IT, and just want it to work. Take a greengrocer, or a supermarket. We don't care about the logistics that go on behind the scenes to get the produce to the store. We just want the banana. The main services currently offered by the cloud providers include services such as communication as a service, compute as a service, infrastructure as a service, and network as a service.

Communications as a Service includes Voice over IP, such a Skype for Business, and secure VPNs that connect remote users. These services are possible without the customer needing to buy dedicated expensive hardware. With Computing as a Service customers can rent virtual servers to host their own workloads with an unlimited number of cores and RAM that is available on demand. Infrastructure as a Service allows you to rent virtualized infrastructure located within the datacenter to run your own cloud applications and servers.

You rent the servers, routers, switches, storage, and firewalls. With Networking as a Service you can use the backbone networking and firewalls and configure the subnets, private and public IP addresses, and all the routing and remote connectivity that you need. The last three cloud services include platform as a service, software as a service, and monitoring as a service. Platform as a Service includes all the middleware tools that you need. You rent the preconfigured platform, which provides you with the tools to build your own applications on.

Examples of PAS include Azure and SQL Services. Software as a Service is where you consume the finished product or software, and have no access to the underlying hardware or customization. Office 365 and SharePoint are examples of Software as a Service, or SAS. Monitoring as a Service allows you to geolocate monitoring tools around the globe that are used to monitor your cloud services and applications from different continents and keep you aware of the activity and any problems.

If we wanted to categorize cloud services in a different way we could look at the type of services that organizations may receive from the cloud. Some of these would then be compute services, such as Azure or Amazon Web Services. Storage services, such as Azure Storage, or OneDrive for Business. Productivity services, such as Office 365, which allows users to collaborate, create, and share documents. Finally, search services, which can embed in-depth search functionality into data stores, such as databases and internet sites using Azure Search.

Finally, for businesses, Windows 10 is now being offered to enterprises as a monthly subscription. In the next movie we will cover the cloud payment models that are available.
