DESCRIPTION
In today’s fast paced marketplace, the demand for product quality and incremental updates is continually increasing. Competing industry goals such as rapid feature development and continual deployment create an environment where release management and risk mitigation can become tenuous. DevOps – a contraction of “Development and Operations" – allows companies to unify the two facets of an organization’s technology department. This presentation covers how DevOps allows companies developing complex systems to integrate their development, testing and deployment processes. We believe in product innovation through rapid software development, and we lived DevOps through our experience as IBM Rational Developers. Presented by: Matthew Clement, Senior Consultant, PacGenesis Matt joined PacGenesis in 2014 as a senior software consultant. Previously he was employed with IBM for twelve years as a software engineer working on enterprise development products across several organizations. Most recently he was a member of the development team for Rational Team Concert with a focus on enterprise extensions and build. Matt graduated with his M.S and B.S from Virginia Tech in 2002 where he majored in Computer Science. Scott Pecnik, Senior Consultant, PacGenesis Scott has been working with IBM Software for more than eight years. He is a former IBM employee where he held various positions throughout the organization, stemming from development to product innovation to pre-sales. Most recently, he was a developer on the Rational Team Concert Enterprise Edition product. Since leaving IBM in 2010, Scott has been consulting for many of the IBM Rational products for customers of all sizes across all industries, focusing specifically on Rational Team Concert. Scott holds two B. S. degrees from North Carolina State University where he majored in Computer Science and Business Management – Finance. Jim Sullivan, Principal and Tech Lead, Arcisphere Technologies Jim Sullivan is the Principal partner of Arcisphere Technologies. Jim was with IBM for 9 years during which Jim supported global clients with ALM, Agile and DevOps solutions. Since forming Arcisphere Technologies Arcisphere is a firm that serves client with products and services for software development, including tools, services, training, and Agile transformations. Jim has achieved certifications in the IBM CLM and DevOps product line. Jim has also achieved Certified Scrum Professional (CSP), and Scaled Agile Program Consultant (SPC) certification for the Scaled Agile Framework (SAFe). Arcisphere was recently accepted into IBM Rational’s SAFe partner ecosystem, and will have a booth at Innovate. Jim has a B.S. in Engineering from NJIT, a Ma

DevOps: An Introduction
Development and Operations
• Contraction of Development and Operations
• Industry History• “DevOps Days” in 2009 in Belgium
• Response to growing interdependence between IT operations and software development
• Associated with lean startup methodologies (JIT Manufacturing)
• What it’s not• A position—you can’t *be* a DevOp
• It’s not a straight forward mix of developer and operations roles—it’s less like granola and more
like soufflé
• Everyone enjoys a good meme…

DevOps: An Introduction
Development and Operations
• What is DevOps?• “... Stresses communication & collaboration … aims to help an organization rapidly produce
software products and services…” –Wikipedia
• “The DevOps movement was born of the need to improve IT Service delivery agility…” –Gartner
• “DevOps is an approach to bridge the gap between agile software development and operations”
–agileweboperations.com
• No standard definition• “SOA is not a technology, but only a style of architecture, or an approach to building software
products” –Mike Liu, 2009
• DevOps is to operations what Agile is to software development.

DevOps vs. Agile
• Development is Agile• Create change
• Add or modify features
• Operations are Static• Value stability
• Enhance services
• DevOps grown out of Agile• Agile accelerates development and operations
• DevOps coordinates them

1. Customer satisfaction
2. Welcome changing requirements
3. Working software delivered frequently
4. Close, daily cooperation
5. Projects built around individuals
6. Face-to-face conversation
7. Working software as metric
8. Sustainable development
9. Continuous attention to design
10. Simplicity is essential
11. Self-organizing teams
12. Regular adaptation to change
• Individuals and interactions over Processes and tools
•Working software over Comprehensive documentation
•Customer collaboration over Contract negotiation
•Responding to change over Following a plan
Values Principles
MethodsPractices
DevOps vs. Agile
•DevOps methods are currently being defined in the industry
•DevOps practices are, like Agile practices, specific techniques of implementing DevOps ideals.
•DevOps principles wide the agile definition to encompass system and operations
•Some call this “infrastructure as code”
•DevOps values are service driven whereas Agile values are software development centric

Why DevOps?
• Addressing the “Execution Gap”
Why DevOps?
Why DevOps?
• Addressing the “Execution Gap”
• Adversarial development interests• Systems of Record (Back End Systems, Databases, etc.) value
stability and usually develop using Waterfall.
• Systems of Engagement (Mobile Apps, Web UI, Distributed systems,
etc.) value time to market and typically develop using Agile Methods
• Coordinate efforts between teams• Closer connection between technology and processes
• Seize market opportunity
• Shorten time to customer feedback

Why DevOps?
Why DevOps?
• Manual processes can be a bottleneck to product
quality
• Fundamentally error prone
• Break down
• Create Waste
• Slow feedback loop
• Add individual resource—this is the brute force
approach.
• Technology on its own is only part of the solution
Why DevOps?
• Complex deployment topology
• Problems get introduced during the deploy of
an application
• Incorrect deployment
• Deploy in a different way
• Undeployed code is loss of revenue
