You will find quite a few articles talking and comparing SharePoint online and on premise. I found an interesting post and just copy and paste below:
In April 2011, Microsoft launched Office 365 – a comprehensive set of Software as a Service (SaaS) solutions that allow any organization to obtain hosted, cloud-based access to Exchange, Lync, Office Web Applications – and SharePoint Online.
All offer guaranteed uptime, fault tolerance, contractual service levels, and clear, predictable pricing.
Few organizations have highly customized Exchange email environments. For many, it’s a no-brainer to migrate existing mailboxes to a hosted version of Exchange, because it simplifies the level of infrastructure support for fault tolerance, recovery, web access, border security, and archiving.
And, the services and configuration used for Exchange service on premises are usually the same among different firms. It’s email.
SharePoint is different. Imagine a world where on-premises SharePoint never existed. (Imagine!) Now, suppose that in a world of Google Docs, Yahoo Mail, and Box.Net, Microsoft had announced a new service that allowed the following:
But that’s not the perception of Office 365-based SharePoint. Instead, there’s a lot of needless focus on “what’s left out.” (SharePoint Online does lack a few features relative to on-premises SharePoint.)
Add up your scores, and see how you match up:
32: You are probably already on SharePoint Online or Office 365. Enjoy the view from your cloud!
24-31: You are a strong candidate for SharePoint Online. Study carefully and understand some of the functional tradeoffs of the platform. SharePoint Online doesn’t support the following:
0-9: If SharePoint is already living in your data center, it’s probably in the right place.
It’s also important to remember that a cloud vision is almost always a future-looking strategy. Since the cloud is uniformly available, it’s easier to deliver content to users with less respect for their immediate location or device (PCs, tablets, smartphones).
Similarly, although Office 365 and SharePoint Online lack features relative to on-premises SharePoint, this isn't expected to be a permanent situation. If we project forward through the next release of SharePoint, we can forecast a time when the on-premises and cloud versions of SharePoint provide nearly identical functions.
What will make it really interesting comes after that – when new features start showing up in the cloud before they are bundled into the next major SharePoint on-premises release. A cloud-hosted SharePoint offering with better functions and simplified ease of operation will be a hard combination to deny for many current on-premises users.

How Do You Choose Between Cloud and On-Premises?
Many organizations start by moving email to the cloud.Few organizations have highly customized Exchange email environments. For many, it’s a no-brainer to migrate existing mailboxes to a hosted version of Exchange, because it simplifies the level of infrastructure support for fault tolerance, recovery, web access, border security, and archiving.
And, the services and configuration used for Exchange service on premises are usually the same among different firms. It’s email.
SharePoint is different. Imagine a world where on-premises SharePoint never existed. (Imagine!) Now, suppose that in a world of Google Docs, Yahoo Mail, and Box.Net, Microsoft had announced a new service that allowed the following:
- Usage on demand
- 100GB of content databases
- Collaboration team sites, extranets, public websites
- My Sites
- Rich browser forms (InfoPath), custom code, and workflows
- Cross-site, self-tuning secure search
- Managed taxonomy and folksonomy
But that’s not the perception of Office 365-based SharePoint. Instead, there’s a lot of needless focus on “what’s left out.” (SharePoint Online does lack a few features relative to on-premises SharePoint.)
Questions Help Determine Answers
Determining whether to use SharePoint Online instead of on-premises SharePoint can be complicated. Here’s a simple set of questions to help determine if SharePoint Online makes sense (see below). For each question, give yourself points as noted in the box.| Question | Yes | No |
| Are you already using custom-coded SharePoint solutions, such as third-party tools or in-house Visual Web Parts? | 0 | 3 |
| Are you free from strict geographic control and accountability for your SharePoint content (e.g., not subject to HIPAA, SAS70, US FDA, Sarbanes Oxley or other regulations)? | 4 | 0 |
| Do you already have SharePoint engineers on staff? | 0 | 3 |
| Do you have a limited IT capital budget, but significant IT operating budgets? | 1 | 0 |
| Do you have a mature, on-premises installation of SharePoint 2010? | 0 | 3 |
| Do you have access to dedicated SharePoint developers? | 0 | 2 |
| Do you have as many or more users outside your corporate network as you do inside the firewall? | 3 | 0 |
| Do you need to downsize or eliminate physical servers and data centers used with SharePoint? | 3 | 0 |
| Do you need to migrate off a legacy installation of SharePoint 2007 or Windows SharePoint Services 3.0? | 3 | 0 |
| Do you need to rapidly set up a pilot or proof-of-concept SharePoint site, independent of any current usage? | 3 | 0 |
| Do you project growth to a very large content pool over the next year (500GB or more)? | 0 | 2 |
| Do you use or need to use SharePoint-hosted business intelligence solutions such as Performance Point? | 0 | 2 |
32: You are probably already on SharePoint Online or Office 365. Enjoy the view from your cloud!
24-31: You are a strong candidate for SharePoint Online. Study carefully and understand some of the functional tradeoffs of the platform. SharePoint Online doesn’t support the following:
- Deployment of custom solutions that require direct access to the server, such as Visual Web Parts. It does support sandboxed solutions, however.
- PowerPivot
- SQL Server Reporting Service Integration
- Business Connectivity Services (originally this was a blanket restriction, but a slipstream release in 2011 added support for access to web services-based remote data in O365 BCS).
- FAST Search Server Integration
- Web Analytics
- Site collections greater than 100GB
0-9: If SharePoint is already living in your data center, it’s probably in the right place.
It’s also important to remember that a cloud vision is almost always a future-looking strategy. Since the cloud is uniformly available, it’s easier to deliver content to users with less respect for their immediate location or device (PCs, tablets, smartphones).
