WHAT IS DEVOPS? People. Process. Products. Build & Test “Dev. Ops is the union of people, process, and products to enable continuous delivery of value to your end users. Continuous Delivery Develop ” Donovan Brown (Microsoft) Deploy Plan & Track Operate Monitor & Learn #Dev. Sum 19

Version everything Automate everything Tokenize configurations Use one-click deployments Deploy the same way to every environment Have always a rollback mechanism in place Build only once Lock down the environments … #Dev. Sum 19

Infrastructure

A regular deployment pipeline

To produce a release, we need to build it from source The resulting application deliverable app is… #Dev. Sum 19

Of couse, it requires a stack of software to execute… #Dev. Sum 19

There are several machines the app needs to run The application is gradually promoted from env to env The same app is pulled from the artifact repository #Dev. Sum 19

The job of the system administrator to ensure that these machines are as identical as possible All changes, patches and upgrades need to be performed on all machines #Dev. Sum 19

Some additional software is missing A resource (directory, . . . ) has been created under the wrong name The wrong version of some software is installed Permissions have been set incorrectly a critical resource (port, . . . ) is occupied Application code is deployed outside of the normal straight-fromsource-control process The operating system has been patched again and again …. #Dev. Sum 19

At the end of the day … #Dev. Sum 19

The whole machine is now packaged as a single immutable unit It contains the entire software stack and it is regenerated by the continuous integration server after every change #Dev. Sum 19

Immutable Infrastructure

Immutable infrastructure is comprised of immutable components that are replaced for every deployment, rather than being updated in-place. Those components are started from a common image that is built once per deployment and can be tested and validated #Dev. Sum 19

Reduce inconsistency in your infrastructure Improve the trust into your deployment process Rollback to an old version is easy Every change is in a script Setting up staging systems is easy and can be automated Testing the new infrastructure in isolation is possible #Dev. Sum 19

We also need tools!
