What is the Lync 2013 High Availability Model?

Problem:• New Lync 2013 workloads &

clients (multi-view video, XMPP, mobility, LWA) require more server resources per user.

• This impacts the number of users per Front-end server.

• SQL backend is the bottleneck preventing Scale-out - adding more servers per Pool (> 10)

• Every transaction needs to be committed to the Database.

• Managing HA for DB is expensive

Solution: Lync 15 Bricks• Front End servers manage user state• Front-end servers keep synchronous

backup copies of their data on 3 other Front-ends.

• Front End servers and Back End databases are “loosely” coupled

• “Lazy writes” to the database for rehydration and disaster recovery

“Bricks” are Front-end

servers used to scaled-out

High Availability - Architecture

• Lync Users are automatically mapped to “Groups”• Each “Group” is dynamically assigned to 3 Front-end servers within a

Pool (a Primary, a Secondary and a Tertiary).• When a user logs in, the Primary server will start servicing all of the

user’s requests. • Changes to the user’s data (such as Contact list changes) will be

synchronously replicated to secondary/tertiary as well (3 replicas).• If a primary server dies, then this group would fail over to the

secondary. (No data loss)• Writes to the back-end database occur periodically (not synchronous).• When a server dies, all the “Groups” assigned to that server as will

failover to different servers (load balancing).

High Availability – How does it work?

• Bob is homed on FE1 (primary) • There are 3 copies of this user’s

data: 1 primary (FE1), 2 backups (replicas in FE2, FE3)

• User is signed in to primary• User’s activities, data are

replicated

Pool Back-end

FE1FE2 FE3

• Primary goes down• User re-signs to one of the backups• Replicated data is available on FE2.
