Where things are today

Grid computing – resources allocated to nodes

So, what’s the problem? Hint…

Evolution of software delivery

Runs cost money!

Fail early, fail cheaply

Extensive alpha and beta testing

Release times (wks) –Windows vs. app

The DevOps paradigm

Development

Operations

“A large segment of DevOps tools delivers automation and configuration to relax stress on developers and operators during continuous delivery… but to support smooth operation data analytics will need to step up to the plate.” http://siliconangle.com/blog/2014/12/23/predictions-for-devops-in-2015-the-year-of-smart-devops/

How can the Cloud better support DevOps-style development AND adopt DevOps concepts itself?

Coordinated Adaptation

Directions for Coordinated Adaptation

• Machine learning to react to enactment point triggers

• Adaptation of both infrastructure and application

• Determination of new enactment points

Some challenges• Multiple layers for adaptation

Coordinated adaptation challenges

• Ultimate effect of adaptation actions at different levels not always clear

• Sample set for machine learning

• Standardizing application adaptations

• …

Example of potential coordinated adaptation

• Computations on a mobile phone vs. in Cloud

• IoT devices – autonomy vs. centralized control

Feedback Drive Design

• Better monitoring information and analysis to help developers

• Analysis of Adaptation Engine efficiency

• Feedback driven testing– Evolution of testing

• Problem recreation

FDD Challenges

• Effective feedback visualization

• Intelligent hints to developers (analysis)

• What-if analysis
