Beyond Infrastructure Automation

We focus on our app code as the origin of business value. Anyone that's ever run apps in prod knows that no value is possible without the entire stack. DevOps has taught us to think about our app stacks holistically. It's time we shift our thinking to an app-centric view of the world. This talk will be an introduction to Habitat (https://www.habitat.sh/), the open source projects that let's use build, deploy, and manage applications. The automation is part of and moves with the application.

This talk was given at Configuration Management Camp Berlin - http://cfgmgmtcamp.eu/berlin-2016/

10. Starts with a plan
11. Simple, native, and declaritive pkg_name=redis pkg_origin=core pkg_version=3.0.7 pkg_license=('BSD') pkg_maintainer="The Habitat Maintainers <humans@habitat.sh>" pkg_source=http://download.redis.io/releases/${pkg_name}-${pkg_version}.tar.gz pkg_shasum=b2a791c4ea3bb7268795c45c6321ea5abcc24457178373e6a6e3be6372737f23 pkg_bin_dirs=(bin) pkg_build_deps=(core/make core/gcc) pkg_deps=(core/glibc) pkg_svc_run="bin/redis-server $pkg_svc_config_path/redis.config" pkg_expose=(6379) do_build() { make } plan.sh Low abstraction Complete dependencies Declare services Simple functions
12. Clean room environment Safe by default Installs dependences Built in a studio
13. Central location Publicly hosted Lightweight views Stored in a depot
14. Easy pattern Shortcuts Increasing specificity Installed by hab
15. Binaries and Config Metadata Side-by-side Packages on disk
16. Docker ACI Mesosphere Post-process packages
17. Run on any 64-bit Linux Easily support proprietary software
18. Installs automatically Keeps things running Manages configuration Supervisor runs services
19. Print config options 12-Factor style Externally enforced Environment configuration
20. More flexible than environment Universal location Externally enforced File configuration
21. Supervisors form a ring Peers Service Groups Gossip Availability increases with scale
22. Supervisors support topologies Dynamic configuration Service group level Uses the ring
23. Supervisors provide update strategies Topology aware Tracks views in the depot Ideal for Continuous Delivery
24. Supervisors provide a REST API External Actors Health and Status Supervisor Debugging
25. Operable Applications • Isolated • Immutable • Configurable • Common interface for monitoring health • Rebuild from source • Common packaging • Runtime Independence
26. Automation travels with the application Existing & Cloud Native Software Application Automation
