Hosted Lync vs Office 365 or Lync Online

It seems that almost every day, somebody asks me which is better - Lync Online / Office 365 or a cloud-based hosted version, such as that offered by telewebica.

Obviously, Lync Online and Office 365 are cloud-based solutions, but they are built for the masses - primarily the SMB/SME market. They are online, low-cost, turnkey solutions, but lack a number of key features that are important to many businesses.

Capability and Feature Differences

Whilst fundamentally the same product, there are a number of significant differences between a hosted implementation of Lync, and that offered by Office 365.

These differences are also valid for On-Premises installations of Lync Server 2013.

There are a number of interesting points that aren't obvious or clearly communicated by Microsoft or their partners.

SharePoint Integration – Microsoft will not integrate with your internal SharePoint environment from Office 365 - even though their collateral implies otherwise.

Enterprise Voice (VOIP/SIP Integration) functionality - Microsoft will not integrate with you PSTN or VoIP based PBX, or even plain old SIP trunks, thus not allowing full telephony functionality. This is only available to hosted or on-premises installations at this time.

Technical Differences

Aside from differences at a product offering level, there are also a number of important technical differences in terms of integration, automation, instrumentation and interoperability.

^* This is an example in the Australian market. Just replace Singapore with Microsoft's Data Centres closest to your region.

Service Level Agreements (SLA)

Both Microsoft and 3^rd party service providers offer Service Level Agreements - or guarantees on uptime and availability.

Whilst calculations vary from provider to provider, the concepts are the same and each option results in a different outcome.

The calculation of an SLA is generally based on the following industry-standard formula.

When a Service Level Agreement is breached, both Microsoft and most 3^rd party providers offer a service credit - effectively a refund on services based on the level of outage.

The SLA levels in green indicate those that have been adopted by the IT industry as a whole, and are regarded as best-practice. Microsoft s Office 365 is somewhat behind in this regard, as their best SLA is significantly lower than the industry standard.

You can see from this, Microsoft will refund your monthly service fees if your services are offline for 3 or more days in a month.

I can't imagine any customer who would be happy with an outage of that long.

Data Sovereignty (or Where is My Data? )

In the technical differences table above, you'll see that Lync Online is hosted by Microsoft in their own Data Centres. This is fantastic, and removes the need for hardware or hosting accounts, and allows Microsoft to offer the product at a heavily discounted rate.

But

Your data is stored there, in their data centres, and accessible by Microsoft. Irrespective of privacy laws in your local region, read the Microsoft EULA carefully. Microsoft has rights to all analytics, and in some cases your data as well. This is generally a good thing, as we're all happy and good citizens.

And unfortunately

You do not have access to this data. Whilst Lync Online includes a small number of basic reports, the vast scale of reporting capabilities built into Lync Server 2013 are not available to you, nor are the raw log files or usage data such as Instant Messaging (IM) conversations, Persistent Chat history or even activity recording.

Support

Microsoft offers email-based support for Office 365 (and Lync), via the online support portal built into Office 365. This is only available for direct Microsoft customers.

Any customers who've purchased from a reseller must go through the reseller for assistance, or ask the reseller to delegate authority to them to contact Microsoft. This rarely happens in the real world.

Any deep technical support or troubleshooting requires a paid-for support agreement as part of an Enterprise Agreement or Premier Support Agreement, and must have Lync included in the agreement schedule.

3^rd Party Providers offering a hosted Lync solution tend to include telephone support as part of the offering as standard - an invaluable point of difference.

So Which is the Right Solution?

It all depends on your requirement and your expectations. Below is a decision matrix that may help identify the best solution.
