Recently, Dr. Qingsong Zhang spoke at a Meetup about how Walmart is using DevOps. Within this slide deck, you'll learn about our DataOps, DevOps and OneOps, an application lifecycle management (ALM), and open source DevOps platform for cloud which was developed by Walmart Labs.

petabytes
The Internet ofThings (IoT) is a system of
interrelated computing devices, mechanical
and digital machines, objects, animals or
people that are provided with unique
identifiersand the ability to transfer data over
a network without requiring human-to-
human or human-to-computer interaction.

Information
Intelligent/
Connected Systems
Data service component in smart
products driving increased value
and differentiation
Big Data
Insights on new products by more
efficiently interpreting massive
quantities of data
Cloud
Demand for apps requires fast, scalable
environments for dev and test, as well as
production
Instrumented Products
Industry requirements demand faster
response to regulations and
standards, with traceability and
quality
Social Business
Broader set of stakeholders
collaborates to deliver continuous
innovation and value

7. What is DevOps
•Culture
•Respect &Trust
•Embrace Change
•Transparent
•Automation
•Continuous integration (CI) and delivery (CD)
•Infrastructure as code
•Lean
•Focus on producing value for end user
•Small batch size
•Measurement (Metrics)
•Measure everything
•Show the improvement
•Sharing
•Open information sharing
•Collaboration & communication

8. Why do we need DevOps
• Technical benefits:
• Continuous software delivery
• Less complex problems to fix
• Faster resolution of problems
• Business benefits:
• Faster delivery of features
• More stable operating environments
• More time available to add value (rather than
fix/maintain)

9. How to DevOps
• Collaborative Development
• Foster productive collaboration
• lifecycle integrations
• Development on the cloud for continuous delivery
• ContinuousTesting
• Enhanced integrations and capabilities to synchronize
software testing with deployment and operations
• Continuous Release and Deployment
• Greater delivery speed and frequency for complex
applications
• Continuous Monitoring
• Capabilities to improve service quality by monitoring
application performance
Agile development approach
• It spans the entire lifecycle, includes
business planning and creation to delivery
and feedback.
• Enable continuous delivery of
software‐driven processes and innovation

15. • Mission:
To enable system developers and
managers to handle modern, web-
based application development and
deployment.
Infrastructure requirements:
Need to support the quantity,
performance demands and diversity
of systems available to a modern
enterprise --- from on-premise
servers to hybrid clouds and
container environments.
• Mission:
To enable data professionals to
optimize for modern, web-based
data storage and analytics.
Infrastructure requirements:
Needs to support highly scalable,
highly available and diverse types of
data and data storage
environments.
