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
