Standard Edition Server
• Standard Edition server is designed for small
organizations, and for pilot projects of large
organizations.
• It enables many of the features of Lync Server,
including the necessary databases, to run on a
single server. This enables you to have Lync Server
functionality at a lower cost, but does not provide
a true high-availability solution.
• The Standard Edition server enables you to use
instant messaging (IM), presence, conferencing,
and Enterprise Voice, all running on one server.
For a high-availability solution, use Lync Server
Enterprise Edition.
Front-End and Back-End Server
• Lync Server Enterprise Edition, the front-end
server is the core server role, and runs many basic
Lync Server functions.
• The front-end servers, along with the back-end
servers, are the only server roles required in any
Lync Server Enterprise Edition deployment.
• Front-End pool is a set of front-end servers,
configured identically, that work together to
provide services for a common group of users.
•A pool of multiple servers running the same role
provides scalability and failover capability.
Front-End Server Features
•User authentication and registration.
• Presence information and contact card exchange.
•Address book services and distribution list
expansion.
• IM functionality, including multiparty IM
conferences.
•Web conferencing, PSTN dial-in conferencing and
A/V conferencing (if deployed).
•Application hosting, for both applications included
with Lync Server (for example, Conferencing
Attendant and Response Group application), and
third-party applications.
Front-End Server Features
• Optionally, Monitoring, to collect usage information in the form of call
detail records (CDRs) and call error records (CERs). This information
provides metrics about the quality of the media (audio and video)
traversing your network for both Enterprise Voice calls and A/V
conferences.
• Web components to supported web-based tasks such as web
scheduler and join launcher.
• Optionally, Archiving, to archive IM communications and meeting
content for compliance reasons.
• In Lync Server 2010 and prior versions, Monitoring and Archiving were
separate server roles, not collocated on the front-end server.
• Optionally, if Persistent chat is enabled, Persistent Chat Web Services
for Chat Room Management and Persistent Chat Web Services for File
Upload/Download.
• Front-end pools are also the primary store for user and conference
data.
Front-End Server Features
• one front-end pool in the deployment also runs
the Central Management Server, which manages
and deploys basic configuration data to all servers
running Lync Server.
• The Central Management Server also provides
Lync Server Management Shell and file transfer
capabilities.
Back-End Server Features
• Back-end servers are database servers running
Microsoft SQL Server that provide the database
services for the front-end pool. The back-end
servers serve as backup stores for the pool users,
and for conference data, and they are the primary
stores for other databases such as the Response
Group database.
• You can have a single back-end server, but a
solution that uses SQL Server mirroring is
recommended for failover. Back-end servers do
not run any Lync Server software.
Edge Server Features
• Edge Server enables your users to communicate
and collaborate with users outside the
organization’s firewalls. These external users can
include the organization’s own users who are
currently working offsite users from federated
partner organizations, and outside users who have
been invited to join conferences hosted on your
Lync Server deployment.
• Edge Server also enables connectivity to public IM
connectivity services, including Windows Live,
AOL, Yahoo!, and Google Talk.
Edge Server Features
• Edge Server also enables mobility services, which supports
Lync functionality on mobile devices. Users can use
supported Apple iOS, Android, Windows Phone, or Nokia
mobile devices to perform activities such as sending and
receiving instant messages, viewing contacts, and viewing
presence.
• Edge Servers also include a fully-integrated Extensible
Messaging and Presence Protocol (XMPP) proxy, with an
XMPP gateway included on front-end servers. You can
configure these XMPP components to enable your Lync
Server 2013 users to add contacts from XMPP-based
partners (such as Google Talk) for instant messaging and
presence.
Mediation Server Features
• Mediation Server is a necessary component for
implementing Enterprise Voice and dial-in conferencing.
• Mediation Server translates signalling, and in some
configurations, media between your internal Lync Server
infrastructure and a public switched telephone network
(PSTN) gateway, IP-PBX, or a Session Initiation Protocol
(SIP) trunk.
• You can run Mediation Server collocated on the same
server as front-end server, or separated into a stand-alone
Mediation Server pool.
Director Server Features
• Directors can authenticate Lync Server user requests, but
they do not host user accounts or provide presence or
conferencing services.
• Directors are most useful to enhance security in
deployments that enable external user access.
• The Director can authenticate requests before sending
them to internal servers.
• In the case of a denial-of-service attack, the attack ends
with the Director and does not reach the front-end servers.
Persistent Chat Server Features
• Persistent chat enables users to participate in multiparty,
topic-based conversations that persist over time.
• The Persistent Chat front-end server runs the persistent
chat service.
• The Persistent Chat back-end server stores the chat
history data, and information about categories and chat
rooms.
• The optional Persistent Chat Compliance back-end server
can store the chat content and compliance events for the
purpose of compliance.
• Servers running Lync Server Standard Edition can also run
Persistent chat collocated on the same server. You cannot
collocate the Persistent Chat front-end server with
Enterprise Edition front-end server.

Lync Server 2013 Administrative Tools
Administrative tools and enhancements in Lync
Server 2013 include:
• Lync Server Deployment Wizard
• Lync Server Control Panel
• Lync Server Management Shell
• Lync Server Topology Builder
• Central management database
• Role-based access control
• DNS load balancing
• Lync Centralized Logging Service
Central Management Database
The Central Management Database:
• Provides a robust, schematized storage of the data
needed to define, set up, maintain, administer,
describe, and operate a Lync Server 2013
deployment
•Validates data to ensure configuration consistency
•Replicates read-only copies of data to all servers in
the topology, including Edge Servers
•Central Management Database replicates
configuration changes to all the servers in your
deployment. Therefore, configuration changes
that you make in location are updated to all
servers of your Lync Server 2013 solution.
Session Initiation Protocol–Based Foundation
• SIP is an application-layer control or signaling
protocol for creating, modifying, and terminating
sessions among one or more participants
• Sessions include Internet-based telephone calls,
multimedia distribution, and multimedia
conferences
• SIP-related RFCs and over 200 IETF Internet drafts
and proposed standards form the basis of the
Microsoft Unified Communications design

Sequence of Lync Server 2013 Deployment Phases
Order of Lync Server 2013 Deployment Phases:
1. Internal Deployment
2. PSTN Dial-in Conferencing
3. External Deployment
4. Enterprise Voice or PBX integration
Assessing Exchange Server Integration and Updating the Design
To support Lync 2013 integration, both Lync 2013
and Microsoft Outlook 2013 read and write
information directly to Exchange Server.
You need to plan for Exchange Server interfaces
used by Lync 2013 and Microsoft Outlook 2013.
You need to plan for:• Exchange Server communication interfaces based on their function.
• Publishing Free/Busy information.
• Controlling integration.
• Lync 2013 and Exchange Server compatibility.
Assessing Client Integration and Updating the Design
You need to assess and determine the requirements
for client integration that may include the
following:
• Client features
• Client deployment
• Hardware and software
• Policies and in-band settings
• Compatibility of client versions
Assessing Voice Requirements and Updating the Design
You need to assess and determine voice
requirements, and the options for voice
deployment may include:
• Using SIP-to-PSTN gateways, which include Survivable
Branch Appliances (SBA)
• Direct SIP by using PBX
• SIP-to-PSTN Gateway to PBX
• SIP Trunking
• Current dialing habits and dial plans
• Devices
