The need for continuous delivery

Significant pressure on business to:

Innovate to create new business value by employing cloud, mobile and social channels and leveraging big data- Systems of Engagement

Integrate with transactional systems- Systems of Record

Balance speed with risk, compliance and quality

Different application components

evolving at different speeds

Primary Workload Type Systems of Record (Transactional)

Systems of Engagement (+ Record)Big Data, Analytics, Mobile/Social Channels

Delivery Model Planned Incremental (DevOps)

Development and Operations Team Sizes

100s and Costly 10s with built-in DevOps automation

Release Frequency Months to Years Days to Weeks, based on business opportunity

Integration Frequency Weeks Continuous

Infrastructure Deployment Days Minutes

Today IT leaders must balance the optimization of existing systems and innovation through new engagement models

Optimization

• Focus on consolidation, virtualization, cost cutting

• Align IT with needs of the CFO

Innovation

• Focus on mobile, intelligent infrastructure,

rapid development

• Align IT with needs of the CMO

So what is DevOps?

Dev + Ops(Thank you…tip your waitress)

A way of re-integrating IT to deliver business value faster and better

Test and Ops teams have increased pressures to keep up with increased loads but continue to use waterfall approaches and traditional tools.

DevOps is…A set of principles and values that facilitate collaboration across disciplines to…

1. Enable rapid evolution of deployed business services

2. Reduce risk, decrease cost, and improve quality

DevOps Principles and Values

• Collaborate across disciplines

• 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

So what is Cloud Computing?

A user experience and a business modelCloud computing is an emerging style of IT delivery in which applications, data, and IT resources are rapidly provisioned and provided as standardized offerings to users over the web in a flexible pricing model

An infrastructure management and services delivery methodologyCloud computing is a way of managing large numbers of highly virtualized resources such that, from a management perspective, they resemble a single large resource. This can then be used to deliver services with elastic scaling

30+ deploys a day…• How do you build features so quickly?

o Software Deploy ≠ Product Launcho Deploys frequently gated by config flags (canary releases)o Validate in production, hidden from public.

• What’s in a deploy?o Small incremental changes to the applicationo New classes, methods, controllerso Graphics, stylesheets, templateso Copy/content changeso Turning flags on/off, or ramping up

• Quickly responding to issueso Security, bugs, traffic, load shedding,o adding/removing infrastructure.o Tweaking config flags or releasing patches.

• No Release Manager
