Introducing Myself
![Page 6: Deploying lync evaluating costs and complexities](https://reader034.vdocuments.us/reader034/viewer/2022051212/559af85f1a28ab96458b4704/html5/thumbnails/6.jpg)
Focus of this Speech
This is a session dedicated to business, so we will not deep dive the technical aspects of the various scenario.
1. A short introduction of Skype for Business
2. An outline of some of the options to deploy Lync Server 2013
3. Related complexities ( “notes”)
4. A short overview of the costs related to Lync
5. A list of features and design decisions that usually add a lot of complexity

Introducing Skype for Business
• Some Skype Metrics
• Over 300 million connected users per month
• Skype users made 2 billion minutes of calls in one day
• 140 million active Skype users on iOS and Android
• Skype continues to be an essential app, ranked in the top 10 most downloaded apps of all time on Windows Phone, iOS and Android

Introducing Skype for Business
• Skype for Business Release
• In the first half of 2015, Microsoft will deliver a new server, a new client and new services in
• Office 365
• Skype for Business is the new name for Lync
• The Skype interface (well known and loved by the users) will be paired with the security and control we have with Lync
• Skype for consumers and the business version will not merge.

Introducing Skype for Business
• Skype Clients Ecosystem
• The applications deployed to end users will be two separated software
• The client has been simplified
• There will be two interfaces inside the next client, "Lync" and "Skype for Business"
• A policy will be available to have the preferred user interface activated
![Page 10: Deploying lync evaluating costs and complexities](https://reader034.vdocuments.us/reader034/viewer/2022051212/559af85f1a28ab96458b4704/html5/thumbnails/10.jpg)
Introducing Skype for Business
• Skype for Web Client
• Right now, a beta of the aforementioned client is available for a limited number of users
• Skype for Business client will be available also as a web interface
• WebRTC

Timing: An Essential Element
• Ongoing Deployment Projects
• Deployment Projects starting in a Few Months
• Deployment Projects starting in the late 2015
![Page 12: Deploying lync evaluating costs and complexities](https://reader034.vdocuments.us/reader034/viewer/2022051212/559af85f1a28ab96458b4704/html5/thumbnails/12.jpg)
How Complex it is to Deploy Lync?
The list of Lync features includes
• Instant Messaging (Chat)• Presence Information• Video Conferencing• Data Sharing• Telephony (VOIP) And Call Control
The more features we deploy, the more complex our infrastructure (and requirements) will be
![Page 13: Deploying lync evaluating costs and complexities](https://reader034.vdocuments.us/reader034/viewer/2022051212/559af85f1a28ab96458b4704/html5/thumbnails/13.jpg)
First Scenario: a Limited, Internal Use Only Lync Server 2013 Deployment
A minimal Lync infrastructure requires and existing Active Directory deployment and is madeup by two servers.
![Page 14: Deploying lync evaluating costs and complexities](https://reader034.vdocuments.us/reader034/viewer/2022051212/559af85f1a28ab96458b4704/html5/thumbnails/14.jpg)
First Note: Deploy Lync Enterprise Voice
The complexity is related to four basic configuration areas you have to setup if we want to use Enterprise Voice:
• Dial Plans• Voice policies• Public Switched Telephone
Network (PSTN) usage records• Voice routes
![Page 15: Deploying lync evaluating costs and complexities](https://reader034.vdocuments.us/reader034/viewer/2022051212/559af85f1a28ab96458b4704/html5/thumbnails/15.jpg)
Second Note: Emergency Services (112)
![Page 16: Deploying lync evaluating costs and complexities](https://reader034.vdocuments.us/reader034/viewer/2022051212/559af85f1a28ab96458b4704/html5/thumbnails/16.jpg)
Second Scenario: Making Services Available to External Users
The infrastructure we have seen in the previous scenario will require two additional elements:
• Lync Edge Server• Reverse proxy
![Page 17: Deploying lync evaluating costs and complexities](https://reader034.vdocuments.us/reader034/viewer/2022051212/559af85f1a28ab96458b4704/html5/thumbnails/17.jpg)

Fourth Note: Public IPs
Fifth Note: DNS
![Page 19: Deploying lync evaluating costs and complexities](https://reader034.vdocuments.us/reader034/viewer/2022051212/559af85f1a28ab96458b4704/html5/thumbnails/19.jpg)
Third Scenario:Multiple SIP Domains
In the previous scenario we have seen a simple Lync deployment dedicated to a single company
Now, what changes if the same company uses multiple names on the Internet?

Fourth Scenario: Adding High Availability
• Additional Edge Server, remove single reverse proxy, Resiliency or Front Ends Pools and voice gateway
![Page 21: Deploying lync evaluating costs and complexities](https://reader034.vdocuments.us/reader034/viewer/2022051212/559af85f1a28ab96458b4704/html5/thumbnails/21.jpg)
Fifth Scenario: Lync Hybrid
• User accounts and related information homed in the on-premises Directory Services and replicated to Office 365
• A part of our Lync users consuming on-premises resources and a part of them using online (Office 365 / Lync Online) resources
• The same (public) domain name used both online and on-premises (Lync split DNS)
• Other Office 365 services and integration with other applications available to all our users

Sixth Scenario: Central Forests and Resource Forests
We have Lync Server installed in a single resource forest
![Page 24: Deploying lync evaluating costs and complexities](https://reader034.vdocuments.us/reader034/viewer/2022051212/559af85f1a28ab96458b4704/html5/thumbnails/24.jpg)
Seventh Scenario: Expanding Resource Forests to the Cloud
Companies that have moved Lync (and Exchange) to the Cloud could still deploy a resource forest configuration.

Sixth Note: Quality of Service (QOS)
• Provide an optimal end-user experience for audio and video communications
• QoS ensure that every call sounds good
![Page 26: Deploying lync evaluating costs and complexities](https://reader034.vdocuments.us/reader034/viewer/2022051212/559af85f1a28ab96458b4704/html5/thumbnails/26.jpg)
Let’s Talk About Money:
• Server Licensing• Licensing the Clients• Office 365
![Page 27: Deploying lync evaluating costs and complexities](https://reader034.vdocuments.us/reader034/viewer/2022051212/559af85f1a28ab96458b4704/html5/thumbnails/27.jpg)
Better Not Together Lync and Virtual Desktops (VDIs) and Remote Desktop Services (RDS)
• Citrix: HDX RealTime Optimization Pack • Microsoft Lync 2013 VDI Plugin
![Page 28: Deploying lync evaluating costs and complexities](https://reader034.vdocuments.us/reader034/viewer/2022051212/559af85f1a28ab96458b4704/html5/thumbnails/28.jpg)
Better Not Together Lync and IP Deskphones
• Lync deskphones require a series of parameters from the:• DHCP server• DNS • For the updates

Better Not Together Lync and Fax
I have used a post from James Cussenas a starting pointhttp://bit.ly/1FnHCTx
• Fax directly connected to the network• Fax hairpinning (official method)• Connect Fax Over G.711 To Sip Carrier (unsupported)• Fax over G.711 To PSTN VOIP Gateway (unsupported)• Fax via SBC With T.38 To SIP Trunk (unsupported)
