What is DevOps

Definition

DevOps Mobile Deployment4 9/29/2016

«DevOps is not a technique or a process, but an approach to enabling seamless

application delivery from inception to production.»

«Devops can be defined as the enterprise capability for continuous software

delivery that enables the enterprise to seize market opportunities and reduce time

to market and improve customer experience.»

«DevOps (a clipped compound of development and operations) is a culture,

movement or practice that emphasizes the collaboration and communication of

both software developers and other information-technology (IT) professionals.»

Culture

DevOps is about breaking down barriers between teams. A key factor for success

is to foster a safe environment for innovation and productivity.

Automation

Automation is not only used to save time and improve productivity, but also to

improve quality by preventing defects and create consistency.

Measurement

DevOps also based on continous improvement which requires data to be

measured and compared. Data should be transparent and accessible to all.

Sharing

Key of success is sharing tools, discoveries and lessons. Try to eliminate duplicate

work and finding people with similar needs.

Mobile vs Desktop

Application Development

Mobile vs Desktop Development

DevOps: Mobile Deployment11 9/29/2016

Definition Mobile Development:

Development of Software (ie. Apps ) targeting mobile devices like mobile phones,

tablets etc.

New Challenges

– Explosion of Run Environments

– More Application as Business Card

– Data Security on Mobile Devices

– Extended Dependencies to third party

– Mobile App Deployment

Explosion of Run Environments

DevOps: Mobile Deployment12 9/29/2016

Cause:

– Platform Fragmentation

Explosion of Run and Development Environments

DevOps: Mobile Deployment13 9/29/2016

Cause: Higher release pace of OS Versions

Explosion of Run and Development Environments

DevOps: Mobile Deployment15 9/29/2016

Explosion of Run and Development Environments

– Application Version: The backend needs to support several versions of the app

Application as Business Card

DevOps: Mobile Deployment16 9/29/2016

Third party app stores

App Portal rating

Failure is not an Option in a B2C scenario

Business to

– Business (B2B)

– Employee (B2E)

– Customer (B2C)

Extended Dependencies to third parties

DevOps: Mobile Deployment17 9/29/2016

Apps need to be build for native platforms

Deployment via Dedicated app stores

External Resource (e.g. External storage or data portals)

Data security in Mobile Apps

DevOps: Mobile Deployment18 9/29/2016

In B2B or B2E environment

BYOD : Confidential data in private Devices

Device Locking versus App Locking

Mobile App Deployment

DevOps: Mobile Deployment19 9/29/2016

Deployment and access to the back ends require different certificates

Many manual steps to create a testable or shippable build

DevOps: Mobile Deployment20 9/29/2016

Mobile DevOps:

Best Practises

Team Profile

DevOps: Mobile Deployment21 9/29/2016

Include both Operating and Development Skills in your team

Promote the DevOps CAMS values by facilitating and example

Continous Integration

DevOps: Mobile Deployment22 9/29/2016

Treat the deployment process as code

– Use automated build and deploy scripts

Separate build and integration areas for each OS

Testing and Monitoring

DevOps: Mobile Deployment23 9/29/2016

Test each Build on simulated and physical devices

Virtualize backend services

Monitor performance

Share the monitoring information to identify bottlenecks

User Feedback to new Features

DevOps: Mobile Deployment24 9/29/2016

Convert user feedback into enhancement requests and user stories

Convert Monitoring Information in Improvement and maintenance Items

Link User Feedback, Monitoring Data and Product Backlog.

Centralized governance of Certificates

DevOps: Mobile Deployment25 9/29/2016

Employ centralized governance for mobile provisioning profiles, certificates, and API keys etc.
