DynamicInfrastructure

Dynamic infrastructureMigrate applications to the cloud and support hybrid and multi-cloud environments. Automate the management of heterogeneous networks, including legacy systems.

• Provisioning and setting up environments • Dynamic scaling of compute resources• Migrating legacy workloads to the cloud• Multi cloud and hybrid cloud deployment• Support for heterogeneous environments

Infrastructure as Code

Automate the Stack

+

Infrastructure as Code• Programmatically provision and

configure components• Treat like any other code base• Reconstruct business from code

repository, data backup, and compute resources

AutomationTurn infrastructure into code—infrastructure as code is versionable, testable and repeatable. Manual processes become a thing of the past.

• Automated, full-stack application policies• Package and service installation• Versionable, testable, repeatable workflow• Scalable application policies• Management of interdependencies across nodes

Chef Server

Revision control system

Chef serverPolicy

State

State queries

Servers, VMs, cloud instances, etc.

running the Chef client

• The Chef server stores policy and configuration data• The Chef client periodically runs on each node in the network• Chef clients poll the server for the latest policies • Chef clients notify the server of their states and can query for the states of other nodes

Describe Infrastructure as Codehttpd_service 'customers' do mpm 'prefork' action [:create, :start]end

httpd_config 'customers' do instance 'customers' source 'customers.conf.erb' notifies :restart, 'httpd_service[customers]'end

directory '/var/www/customers/public_html' do recursive trueend

Test the Codedescribe 'apache::default' do context 'When all attributes are default, on an unspecified platform' do

let(:chef_run) do runner = ChefSpec::ServerRunner.new runner.converge(described_recipe) end

it 'converges successfully' do expect { chef_run }.to_not raise_error end

it 'installs apache' do expect(chef_run).to install_package 'apache2' end endend

UBIQUITOUS WORKFLOW AUTOMATION

DevOps workflow & cultureEliminate silos and lower the overhead of IT operations and service management by supporting DevOps culture. Build communities.

• Unified workflow for application and infrastructure

• Integration with version control for dev and ops

• Support for automated testing of infrastructure and applications

• Integration of security and compliance into product development

• Advanced, high-velocity workflow

The rewards?*

*source: Dr. Nicole Forsgren research on DevOps

More deployments

Ship faster

Faster MTTR after issues More profits, market share, and productivity

Market cap goes up

Fast Flexible Infrastructure•Run the same configurations regardless of environment: Repeatable and Reliable

•Chef integrates with numerous cloud providers•Run your Chef Server in the cloud, in your datacenter, or use Hosted Chef

Where Does Chef Integrate with IaaS•Provisioning – creating new resources•Management – alter resources over their lifecycle•Destroy – sunset resources that are no longer needed•Supported features and resources vary by provider•Testing environments – the Test Kitchen project can use numerous providers for testing chef code / infrastructure provisioning

Chef and AWS•Manage hosts, EBS volumes, EIPs, ELBs, Cloudwatch, CloudFormation, IAM users, etc• Flexibility of custom resources and Ruby allows us to expand and update support regularly

•Provision, manage, and destroy resources as needed•Launch Chef Automate directly in the cloud via the MarketPlace

Chef and AWS Customers•Scholastic

• World’s largest publisher of material for children• Datacenter update / modernize – didn’t want to be in the datacenter management business

• Targeted public cloud• Worked through a rearchitecture of projects for cloud readiness

Chef and MSN•MSN runs on Azure now with Chef

Other Cloud Platforms and Providers•Google Cloud Platform•OpenStack•Linode•Rackspace•Terremark•VMware / vSphere

Cloud Lead to Our Journey to CI/CD•Helped many customers build reliable, repeatable infrastructure•Brought testing into Infrastructure teams with Test Kitchen•Overall application delivery pushed into build pipelines and integrated with infrastructure

Continuous delivery of infrastructure & appsImplement a high-velocity software delivery pipeline that integrates application and infrastructure. Eliminate the risks incurred with large, infrequent releases.

• Rapid provisioning of dev and test environments

• Ensure consistency and repeatability of environments

• Unified pipeline for infrastructure, runtime environments and applications

• Support for large teams with multiple projects

• Advanced, high-velocity workflow

ONE PATH FOR CHANGE

• The way change moves through your organization is fixed

• Designed to re-enforce your principles and aid flow

• Flexible at the level of execution

CODE GOES THROUGH THE SAME WORKFLOW

Applications are codeInfrastructure is code

Security and compliance at velocityRegulatory compliance and security concerns are facts of life for every enterprise. At the same time, competitive pressures are increasing. Embed requirements into the software delivery pipeline. Code makes compliance at velocity possible.

• Embed compliance into the software delivery pipeline

• Automated checking of compliance criteria with analytics

• Structured review process during development

• Discovery and analysis• Patch management and remediation

SSH Control

SSH supports two different protocol versions. The original version, SSHv1, was subject to a number of security issues. Please use SSHv2 instead to

avoid these.

Where did that lead us?

Habitat Project• Launched in June 2016 – still a baby!• “What is Chef thinking about containers/microservices/orchestration”

What is Habitat• Automation that focuses on the application rather than infrastructure

• Infra is there because the Apps need it to be useful• Builds repeatable, documented stacks for apps and dependencies• Explicit versioning of apps and deps• A supervisor for coordination and run-time configuration

Why?• Portability• Accountability

• Know exactly what is going into your environment• Build the same every time, no substitutions of new layers without recording

• Built in organization and monitoring by the supervisor

Pieces of Habitat• A bit more complex than working in Chef• Build in a “clean room” environment called the habitat studio

• Limit the effects of external influences, undocumented accidental dependencies• Produce packages for standalone run-time or export to container

platforms

Plan Filespkg_origin=<youroriginname> pkg_name=mytutorialapp pkg_version=0.2.0 pkg_maintainer="The Habitat Maintainers <humans@habitat.sh>”pkg_license=() pkg_source=https://github.com/habitat-sh/habitat-example-plans pkg_deps=(core/node) pkg_expose=(8080) do_download() { return 0 }

do_verify() { return 0 } do_unpack() { return 0 } do_build() { … }do_install(){ … }

Run the thing you built. Everywhere.

Extra cool stuff via the supervisor• --bind• --peer• Manipulate config at runtime and push updates

Hard Stuff• Apps may need altering

• Bits aren’t going to always be in the same places as expected, due to clean room idea and dependency isolation

• Not everything has been habitatified yet• Still work going on for integrations with container platforms and other

components• You will need access to the Internet

• Scary!• Windows is on the way
