MOBILE & THE CLOUD
phone home
most non-trivial mobile apps require a back-end
MOBILE & THE CLOUD
what do you need from back-end?
• support all phone types– plus tablet and browser
– don’t forget feature phones
• rapid development
• performance and scalability
• reliability
• security– identity management
– connect with existing / internal systems
• cheap
ENTER THE CLOUDbut what is it?
MOBILE & THE CLOUD
Cloud = The Internet
• websites
• Software as a Service (SaaS)
– Salesforce.com, Dynamics CRM Online, BPOS/Office365, …
– countless other enterprise and consumer SaaSISVs
– often – but not always – browser-based
• store your data “in the cloud”
– Skydrive, Dropbox, Mozy, Nasuni, …
MOBILE & THE CLOUD
Cloud = Utility Computing
• implies back-end
• easy to add computing power
• easy to subtract computing power
MOBILE & THE CLOUD
history: ancient times
• physical boxes
• new workload? new server
MOBILE & THE CLOUD
history: recent times
• virtual machines
– 1 physical box can house multiple (2, 10, 100,
…) “virtual” computers (VMs)
• new workload? new VM
• standardized physical hardware
– VMs look just like physical computers to
application software
Virtualized Environment
MOBILE & THE CLOUD
benefits of server virtualization
• cost
– server consolidation/improved utilization
• manageability
– more flexible HA/DR scenarios
• hosters have used VMs for many years
• sidebar: multiple types of virtualization
MOBILE & THE CLOUD
along comes Amazon
• one of the biggest, best ecommerce sites
• demand peaks at holidays
• “Can we sell our excess capacity?”
• the (public) cloud is born
– August 2006 beta, October 2008 “release”

MOBILE & THE CLOUD
what’s different?• no long-term contract
• pay in 1-hour increments
• launch new compute capacity (VM’s) in minutes– even by “remote control” (API)
• implications– experiment cheaply
– handle peaks
– level playing field
– CapEx to OpEx
– develop for HUGE scale• assuming you already know how to write stateless web apps
MOBILE & THE CLOUD
the market grows
• Microsoft
• Rackspace and other “traditional” hosters
• VMWare
• Salesforce.com
• Heroku.com
• “Me too!”
MOBILE & THE CLOUD
economies of scale
• Microsoft and Google are investing billions each year in
data center capacity
• whitepaper: massive TCO savings in public vs private
– 100 servers: cost prohibitive
– 1000 servers: 10 times the cost of a public cloud

increasing complexity
different types of clouds
SaaS
Software as a Service (Office365, salesforce.com, …)
• Customer-ready
• Often self-service
• “Just use it”
• Don’t care about guest
OS
• Assumed to be scalable
IaaS
Infrastructure as a Service (Amazon, rackspace, VMWare, partners)
• Operations-ready
• Can be self-service
• “VMs on demand”
• Customer must manage guest
OS
• Great if you already know how
to write scalable apps or if you
want to run legacy apps
PaaS
Platform as a Service (Microsoft, Google, Salesforce)
• Developer-ready
• Mostly self-service
• “Write a chunk of code”
• Don’t have to manage
guest OS
• Easy to scale (stateless
web apps by default)
• Easy to operate / HA
DR built in

MOBILE & THE CLOUD
so does cloud work for mobile?
• support all phone types: YES, via RESTful APIs and pages– plus tablet and browser: YES
– don’t forget feature phones: YES
• rapid development: YES, in various ways (e.g., deployment)
• performance and scalability: YES, easy to add resources
• reliability: YES, built-in or easy-to-add HA
• security: YES, data centers follow consistent best practices– identity management: more and more
– connect with existing / internal systems: more and more
• cheap: YES, a lot cheaper than self-hosting
MOBILE & THE CLOUD
scenarios• mobile app as isolated business
– productivity
– game
– collaboration/social
• expanding existing solution with mobile– consumer/soho
– enterprise/smb
• custom corporate mobile solution
• marketing-based solution
• quick-n-dirty – don’t overlook html and jQuerymobile
MOBILE & THE CLOUD
cloud architecture questions
• how will you be managing identity?
• how will you partition data for customers?
• do you need relational storage or is “no SQL” a better fit?
• how will you monitor usage? determine scalability factors?
• do you need to connect through corporate firewall?
• do you need to expose/sync with internal data?
• are you migrating from on-prem/self-hosted
