Now that you know what cloud computing is and some of the pros and cons of cloud computing, we are going to explore the types of cloud solutions out there. While there is this general idea behind the cloud – that applications or other business functions exist somewhere away from the business itself – there are many versions that companies look to in order to actually use the technology. Remember, cloud computing offers a variety of ways for businesses to increase their IT capacity or functionality without having to add infrastructure, personnel, and software.
Pure Cloud: With this type of solution, all of your applications and data are put outside your firewall, in the cloud, and are accessible from devices including; laptops, desktops, iPads, iPhones, Android devices, and other devices via the Internet.
Hybrid Cloud: While technically viable, “pure” cloud computing really freaks some people out. In some cases, it’s simply not the best solution due to compliance issues, security or performance concerns.
With a hybrid cloud solution, parts of your existing IT infrastructure, like email or file storage, can be moved to the cloud, and the rest of your IT infrastructure stays on site. You can then enjoy the cost savings and benefits of cloud computing—where it makes sense—without risking your entire environment.
Point Solutions: Moving certain applications to the cloud, like SharePoint or Microsoft Exchange Server, is another option. Email is typically considered a critical application that everyone needs access to from any device in any place. Moving Microsoft Exchange to the cloud is a great way to get all of the advance features and benefits of Exchange without the cost of installing and maintaining your own in-house server.
Public Cloud vs Private Cloud: Public cloud services are that which anyone with a network connection and typically a credit card can tap into. There is a shared infrastructure that is usually a managed via a self-service website that allow you to “pay-as-you-go”. Private clouds are basically infrastructures that mimic public cloud services, but are at your site or data center. They are often the choice of businesses that want the benefits of cloud computing, but don’t want their data in a public environment.
