Velocity 2011: Production Begins in Development

The document discusses the rise of DevOps as a new IT operations support model enabled by large cloud providers. It argues that DevOps will emerge because it is not solely driven by top-down implementations, and enables IT organizations to look for new models enabled by tools like Chef, Puppet, and Docker. DevOps adoption will be stimulated by the growing interest in tools that help align development and operations teams.

Clouds DevOps Continuous Delivery/Deployment Lean Startup Alignment Quality Cycle Time
It all starts in Development
It all starts in Development But what do we tell them to do and how do we get them to do it?
Share ownership of availability • Developers must wear pagers • Incident command training so everyone knows their roles • Notification mechanism? Access provisioning?
Non-functional requirements are first class citizens • All of the “-ility” requirements • As much a part of your service as the businessʼs functional requirements • Manage through same process • Make sure they are on the schedule • Donʼt over commit
Strive for parity between dev & prod • Develop test data fixtures for all environments • Implement Mock Services for major infrastructure pieces for Developer user. • Continuous integration means integrate early • Use the deployment, config, and packaging tools in dev
Push config management discipline back to Dev • Dev is about creating variation, Ops is about eliminating variation • Augment deployment toolchain to support the variation • Do developers use the tools? • Do developers like them? • Devʼs need config too • Accept config contributions and patches from dev
Packaging... itʼs not just for the OS • If you want to be a high performing web operations organization, you need to take change management seriously. • Strict versioning is needed, and package managers do that. • Itʼs about being idempotent. • Transfer packaging responsibility to dev • Define the packaging constructs you will support http://webscalebook.com
Config is code • if itʼs code it needs to be managed like code... • Should be transparent and identical SDLC in both dev and ops • Avoid or eliminate asymetric release processes
Tailor release artifacts to roles • “Small teams make better software” • Make sure one team getting stuck doesnʼt prevent another team to release (org coupling) • Large codebases suffer software entropy effects • Build an infrastructure that can reliably manage lots of smaller artifacts • Org conflict is a good time to suggest breaking up a codebase into separate concerns
Standard management vocabulary • Consistent and expected management behavior • Across components and releases • “start, stop, status, update, install...”
Rollback • Rollback that works • No, really works • Seriously, really really works • You say it will work? Test it right now
Standard metrics abstractions • Dev surface metrics to Ops • Avoid the back and forth conversations • Use a standard framework • Use standard types (gague, counter, timer...) • Ops knows what to expect and how to visualize https://github.com/codahale/metrics
Push test ownership to the edges • QA is “Quality Assurance” • QA writing tests = bottleneck • QA writing tests = avoiding responsibility • QA is architecture / tooling / assurance • Test Driven Development • Test Driven Operations (yes, you too) • Bottom line: Everyone owns quality.

    It all startsin Development But what do we tell them to do and how do we get them to do it?
  • 31.
    Share ownership ofavailability • Developers must wear pagers • Incident command training so everyone knows their roles • Notification mechanism? Access provisioning?
  • 32.
    Non-functional requirements are first class citizens • All of the “-ility” requirements • As much a part of your service as the businessʼs functional requirements • Manage through same process • Make sure they are on the schedule • Donʼt over commit
  • 33.
    Strive for paritybetween dev & prod • Develop test data fixtures for all environments • Implement Mock Services for major infrastructure pieces for Developer user. • Continuous integration means integrate early • Use the deployment, config, and packaging tools in dev
  • 34.
    Push config management discipline back to Dev • Dev is about creating variation, Ops is about eliminating variation • Augment deployment toolchain to support the variation • Do developers use the tools? • Do developers like them? • Devʼs need config too • Accept config contributions and patches from dev
  • 35.
    Packaging... itʼs notjust for the OS • If you want to be a high performing web operations organization, you need to take change management seriously. • Strict versioning is needed, and package managers do that. • Itʼs about being idempotent. • Transfer packaging responsibility to dev • Define the packaging constructs you will support http://webscalebook.com
  • 36.
    Config is code •if itʼs code it needs to be managed like code... • Should be transparent and identical SDLC in both dev and ops • Avoid or eliminate asymetric release processes
  • 37.
    Tailor release artifactsto roles • “Small teams make better software” • Make sure one team getting stuck doesnʼt prevent another team to release (org coupling) • Large codebases suffer software entropy effects • Build an infrastructure that can reliably manage lots of smaller artifacts • Org conflict is a good time to suggest breaking up a codebase into separate concerns
  • 38.
    Standard management vocabulary •Consistent and expected management behavior • Across components and releases • “start, stop, status, update, install...”
  • 39.
    Rollback • Rollback thatworks • No, really works • Seriously, really really works • You say it will work? Test it right now
  • 40.
    Standard metrics abstractions •Dev surface metrics to Ops • Avoid the back and forth conversations • Use a standard framework • Use standard types (gague, counter, timer...) • Ops knows what to expect and how to visualize https://github.com/codahale/metrics
  • 41.
    Push test ownershipto the edges • QA is “Quality Assurance” • QA writing tests = bottleneck • QA writing tests = avoiding responsibility • QA is architecture / tooling / assurance • Test Driven Development • Test Driven Operations (yes, you too) • Bottom line: Everyone owns quality.
  • 42.
