• What are we trying to solve?• How our customers are looking at the problem• Enable yourselves with smart tools• DevOps is not Dev+Ops• Business results

AGENDA


Treat your Infrastructure as Code


• Inefficient workflows• Admin errors• Misspeled infromation adn configruations

WHAT ARE WE TRYING TO FIX?


BANE OF MY EXISTENCE


How long would it take your organization to deploy a

change that involves just a single line of code?

- Mary Poppendieck


• It’s lazy and time consuming• Non-repeatable• Breaks automation patterns

STOP CLICKING!


If you do one thing10 times in a month,

automate it


• Modern tools and workflows• Testable and repeatable patterns• Better planning when rolling out new app versions• Happier colleagues

WHAT IS THERE TO GAIN?


What are our customers doing?


Infrastructure As Code


Everything As Code


Storage Network Compute


Storage – Network - Compute

OS DNSDHCP DB


Storage – Network - Compute

OS – DNS – DHCP - DB

Apps Services Toolsets


RackHD


• Containers (Docker, Rkt, LXC)– Puts application and its requirements in a container, then

runs it for you• PaaS systems (Cloud Foundry, Deis, Heroku)

– Takes your code and automatically adds the needed requirements, then runs it for you

• Configuration management systems– Puppet, Chef, Ansible, Salt– Manages your app and its requirements based on your

explicit configurations

TOOLS - APPLICATIONS


APPLICATIONS RUN IN CONTAINERS

EXAMPLE – APPLICATIONS


• Deployment (RackHD, Terraform, Vagrant)– Deploying an OS is now seen as standard fare, not

something just done once• Configuration management systems

– Make sure services and OS settings are correctly applied

TOOLS – BASIC SUPPORT INFRASTRUCTURE


resource "vsphere_virtual_machine" ”mysql" { name = “database-01“ domain = “corp.local“ datacenter = “DC-02" cluster = “Cluster-03" vcpu = 2 memory = 8192 disk { datastore = “XTREMIO-04" template = "templates/centos-7.0-x86_64” iops = 10000 } gateway = “192.168.1.1" network_interface { label = “CORP-LAN" ip_address = “192.168.1.150" subnet_mask = “255.255.255.0" }}

EXAMPLE – BASIC SUPPORT INFRASTRUCTURE


node 'database-01.corp.local' { class { '::mysql::server': root_password => 'strongpassword', override_options => { 'mysqld' => { 'max_connections' => '1024' } } } mysql::db { 'mydb': user => 'admin', password => 'secret', host => 'database-01.corp.local', } }

EXAMPLE – BASIC SUPPORT INFRASTRUCTURE


• Deployment– RackHD, Puppet, Chef, Ansible– VMware Auto Deploy, Arista Zero Touch Provisioning

• Monitoring– Sensu, Prometheus, Zabbix, Nagios

• Logging– Logstash, Splunk, Fluentd

TOOLS – SOFTWARE-DEFINED INFRA


• Developer or outsourcer creates a new app• The application’s functionality is verified by

automated testing• The app is bundled into a Docker container• The container image is marked for release

AN EXAMPLE WORKFLOW – STEP 1


• Power on server• RackHD deploys your tested and verified OS• Puppet then deploys the needed software and

configures logging and monitoring



• The server is now part of a larger resource cluster• The application gets rolled out by pushing the

container to the platform• Then we start again

Planning and coordination between the responsible teams is vital



DevOps is an operations model where software

development principles are applied to operations


• No manual packaging• No manual configurations• No manual deployments• Configurable, testable and reliable• Executable documentation

END RESULT


• Roles and responsibilities mostly stay the same• Application developers will not roll out infrastructure

changes• Operations teams will not create new business

generating apps

The thing that’ll change is HOW you do you job

HOW WILL MY JOB CHANGE?

• Stop clicking, automate!• Invest time and money in your operations –

No one wants to fight fires every day• Focused groups that collaborate can accomplish

more• Executable documentation leads to less failures
