Lync Server 2013 Deployment options.

Lync Server 2013 Deployment options.

There are many article found on Lync 2013 and they are explained the deployment process however did found the article where all Lync 2013 deployment combination available. That’s why I thought I will write article where you see the deployment option.
Broadly the Option available for Lync 2013 deployment.
1.     Lync On-Premises deployment.
2.     Lync Hybrid Deployment.
3.     Cloud (Office 365) Deployment.
These deployment option available as per requirement and you can combine these deployment options.
Lync Server 2013 On-premise Deployment:-

Lync 2013 On-premise deployment is my go to option because it will provide complete Lync feature set and provides ultimate flexibility in configuring, customizing, and operating your deployment. All servers are installed onsite and maintained by your organization. An on-premises deployment provides the full range of Lync Server features.
a.     Full Enterprise Voice Capabilities -On-premises supports direct connectivity with PBX systems and trunks, and advanced phone features such as response groups and Call Park. Lync Online does not currently support these features.

b.     Media Quality Controls - If you want the full range of media quality assurance features, such as Call Admission Control (CAC) and Quality of Service (QoS) features, you will want an on-premises deployment.

c.      Persistent Chat - If you need to deploy Persistent chat for your organization, you must choose an on-premises deployment.

d.     3rd-Party Server Applications.   [Only on-premises deployments can work with trusted 3rd-party applications that use the Microsoft Unified Communications Managed API (UCMA)].

e.     Multi-National/Multi-Regional Companies Needing Regional Support.   If you have datacenters in multiple countries or regions and need servers to be deployed and managed on a regional basis, an on-premises deployment is best, as it provides this type of regional management capabilities.
f.       Complete control over policies, reports, and upgrades etc.

Lync Hybrid Deployment:-
This type of deployment will support of mixed Lync environment means some user homed On-premises and some are homed on Lync online but share the same domain ( You can configure your on-premises deployment for hybrid with Lync Online and use Active Directory Synchronization to keep your on-premises and online users synchronized. You can also configure hybrid deployments for integration with other Microsoft Office 365 applications, including Exchange Online and SharePoint Online.
Need to keep in mind following points:
a.     User contacts - The limit for contacts for Lync Online users is 250. Any contacts beyond that number will be removed from the user’s contact list.
b.     Instant Messaging and Presence - User contact lists, groups, and access control lists (ACLs) are migrated with the user account.
c.      Conferencing data, meeting content, and scheduled meetings - This content is not migrated with the user account. Users must reschedule meetings after their accounts are migrated to Lync Online.  
Cloud (O365) Lync online:-
You have purchase Lync Online as a standalone service from Microsoft Office 365 or as part of an Office 365 for enterprises suite that includes Lync Online, Microsoft Exchange Online, Microsoft SharePoint Online, Microsoft Office Professional Plus, and Microsoft Office Web Apps.
Organizations that subscribe to Lync Online retain control over the collaboration services they offer to users, but they do not have the operational burden of on-premises server software. With the Lync Online multi-tenant hosted plans, Lync is hosted on multi-tenant servers that support multiple customers simultaneously.
a.     Real-time presence information—including photos, availability status, and location.
b.     Make voice calls through your computer to other Lync or Skype users in your organization or in other organizations that use Lync or Skype.
c.      Create, moderate, and join pre-planned and on-the-fly audio, video, and web meetings with people inside and outside your organization.
d.     Enhance online presentations with screen-sharing and virtual whiteboards.
e.     Let customers participate in your Lync conference calls even if they are not Office 365 or Lync Online customers.
Thank you.
