13. DevOps for Mobile - Challenges
 Mobile Apps are the front-end to a
complex(enterprise) back-end
system
–Mobile Apps are rapidly becoming a
critical user interface to enterprise
systems
–But they are just one part of a multi-tier,
multi-component application “eco-
system”
–Developing and delivering mobile apps
requires coordination across that whole
eco-system

15. DevOps for Mobile - Challenges
 Fragmented Platforms
– Multiple mobile operating
systems
– Multiple devices & form factors
– Multiple implementation
technology choices
 Frequently a mix of technology is
involved for mobile app
implementation
 App stores add additional
asynchronous deployment step

16. Mobile Application Architecture: LinkedIn
http://engineering.linkedin.com/testing/continuous-integration-mobile

17. DevOps Principles and Values
 Develop and test against a production-like system
 Iterative and frequent deployments using
repeatable and reliable processes
 Continuously monitor and validate operational
quality characteristics
 Amplify feedback loops

37. Roadmap for UrbanCode
Enabling clients to more rapidly deliver mobile, cloud, big data analytics and traditional
applications with complementary DevOps capabilities
 Drive down costs
 Reduce the amount of manual labor,
resource wait-time, and rework
 Speed time to market
 Increase frequency of software delivery
 Reduce risk
 Deliver higher quality application
releases with increased compliance
“Mobile development moves more quickly than most enterprises are accustomed to. The coordination
required, and the pace being driven by mobile, is a big factor driving DevOps in the enterprise.”
- Eric Minick, UrbanCode.

38. Multi-tier mobile apps present specific challenges to DevOps
Middle Tier ServerClient Tier Devices Back-end Data & Services
Mobile-specific
challenges:
Lots of device targets
Provisioning rules and
artifacts
Curated App Stores
Dependent upon
backend service
versions
The Mobile-specific challenge in DevOps is mainly:
1.Dealing with the specific issues in the Mobile Client tier
2.And subsequently coordinating separate pipelines for each
tier:
 Mobile Client
 Middleware
 Back-end data and services

39. Examples of mobile continuous delivery
