Win·dows·Az·ure [win-dohz-azh-er]
Noun: A comprehensive set of services that
enable you to quickly build, deploy and
manage applications across a global network
of Microsoft-managed datacenters.
99.95% Monthly SLA
Pay only for what you use

MongoDB on Windows Azure provides all the
benefits customers have come to expect from cloud
computing: elasticity, on-demand capacity, faster
time to market, and pay-for-what-you-use pricing.
• MongoDB offers built-in support for horizontal
scaling and sharding
• Windows Azure offers built-in support for
responsive auto-scaling

14. Replica Sets: High Availability

19. Deploying to Virtual Machines
– Compared to worker role (PaaS), VM-based
replica sets offer more control, as
well as more responsibility
– MongoDB Installer for Windows Azure is a great learning tool.
Not typically used for production deployment.
• Puts MongoDB on OS disk instead of attached disk
• Limited to 30gb, not performant for writes, Windows-only
• http://www.mongodb.org/display/DOCS/MongoDB+on+Azure+VM+-
+Windows+Installer
• .deploy-mongo.ps1 <node-count> <dns-prefix> <image-name>
<password> <location> <pub-settings-file-path> [replica-set-
name]

azure vm create mongoc9 "OpenLogic__OpenLogic-CentOS-62-20120531-
en-us-30GB.vhd" username password -l "West US" -e
azure vm create mongoc9 "OpenLogic__OpenLogic-CentOS-62-20120531-
en-us-30GB.vhd" username password -l "West US" -e 23 -c
azure vm create mongoc9 "OpenLogic__OpenLogic-CentOS-62-20120531-
en-us-30GB.vhd" username password -l "West US" -e 24 -c
azure vm endpoint create mongoc9 27017 27017
azure vm endpoint create mongoc9-2 27018 27018
azure vm endpoint create mongoc9-3 27019 27019
To set up MongoDB, SSH into each instance and:
get mongodb binaries and install
create db dir
start mongod, initialize replica set

24. PaaS
Deploying MongoDB replica sets on
Windows Azure worker roles
(cloud services)

25. Deploying MongoDB as a Cloud Service
– Windows Azure cloud services
run on a fully automated, highly
scalable cloud platform
– Ongoing management of the OS and infrastructure is
handled by Windows Azure
– Infinitely scalable, on demand
– App and MongoDB in same cloud service provides security
– PaaS approach is the easiest way to deploy MongoDB on
Windows Azure
– For quick and simple deployment, use the MongoDB on
Azure Worker Role:
http://www.mongodb.org/display/DOCS/MongoDB+on+Azure+Worker+Roles
