Every time I read about “the cloud” I want to drag out a red pencil and edit the sentence.Why? Because we should really be talking about “the clouds,” plural.
There are dozens of cloud hosting options for SharePoint, beyond Office 365. Amazon, Rackspace and Fpweb offer compelling alternatives to Microsoft’s public cloud for SharePoint online with a mix of capabilities.
These capabilities fall on the spectrum between two options:
- IaaS (Infrastructure as a service) -- cloud hosted VMs on which YOU install Windows, SQL, SharePoint.For better or worse, you have complete control over administration and customization.
- SaaS (Software as a service) -- fully managed solution delivering SharePoint services with full subscribed provider managed availability, backup, performance, installation, etc.For better or worse, you have limited control of administration and customization.
Now, it’s debatable that Office 365 itself is a pure SaaS solution -- you carry a lot of responsibility for managing your own security and content.Let’s suppose that Azure hosted virtual machines represent IaaS and Office 365 represents SaaS.
How best to decide?Try the following survey. Give yourself points for each answer, and use the key at the end to see how your situation compares:
You are comparatively free of the history and capabilities of many on-premises environments.As a result, you’re a strong candidate for Office 365.You will get immediate benefits from the platform services without needing to disrupt existing content patterns or internal processes.
You have the classic posture of an on-premises environment.If you are trying to gain some of the advantages of the cloud, an IaaS solution like Azure VMs may be a stronger fit for your organization.Based on your use cases, a hybrid between O365 and Azure may also introduce some of the service simplicity of Office 365 with the complete admin control from Azure.
On premises forever!You can work on other projects for the year while your needs progress and the solutions improve.
Obviously, your use cases may vary significantly form those mentioned here.This is intended to help you assess your success criteria relative to the business cases and economics.Best of luck with your cloud(s) evolution.
