OpsManager
OpsManager
Relieving the pain associated with manually
managing your large-scale MongoDB estate.
2. Goals
• Ops Manager, Cloud Manager, Atlas
– What are they?
– How do they differ?
– Why do I need them?
• Ansible
– What is it and how can I use these tools to relieve some
pain in my life?
3. Show of
Hands
• Who’s Here?
– DevOps/Ops?
– Site Reliability?
– Engineer?
– DBA?
– Developer?
4. Admin
Evolution
3. Puppet, Salt,
Ansible
Leveraging automated solution for
config mgt, some cloud deployment.
1. Manual
Download by hand, build server from
CD, Manually Start and Config Services.
2. Scripting
Write scripts to maintain
configurations, copy those to
servers and run them.
4. Cloud/Hybrid
Automation
Full Cloud-based pro-
visioning and
management
5. Managing databases manually can be...
• Painful
• Risky
• Complex
• Susceptible to
human error*
• Unnecessary...
* 80% of all downtime due to people/process error (Gartner)

WHAT IS ANSIBLE?
Confidential
It’s a simple automation language that
can perfectly describe an IT application
infrastructure in Ansible Playbooks.
It’s an automation engine that runs
Ansible Playbooks.
Ansible Tower is an enterprise
framework for controlling, securing
and managing your Ansible
automation with a UI and RESTful API.

29. Getting Started with Ansible - Lexicon
• Commands
– ansible, ansible-playbook
• Configuration
– ansible.cfg
• Modules
– Hundreds of stand-alone scripts to solve common requirements
• Plays, Playbooks
– The execution tools to carry out your management tasks
• Tasks
– The components that connect ansible to the servers
30. Why Ansible?
• Simple
• Human Readable
• Agentless (uses SSH)
• Popular - Lots of Modules
• Used by Twitter, NASA, Spotify
32. Follow Along
• Git (or download)
– git clone http://github.com/mrlynn/ansible-demo
– Thank you Torsten Spindler
• Ansible
– brew install ansible
• Pipe Viewer (optional)
– Simulates typing
• AWS->EC2
– Keys Set Up
33. Post-Demo Check-in
• Atlas
– DBaaS
– Deploys new MongoDB Clusters from zero to cluster in minutes.
• Ops Manager
– Automation for all the things you do with MongoDB - except deploying the agent.
• Ansible
– Automation for configs, deployment and more - especially deploying O/M Agents
I hope you learned some ways you can relieve the pain associated with manually
configuring, deploying and maintaining your database environment.

44. Demonstration Setup
Command Description
ansible -m ping -i ansible-hosts all Using the ping module and the hosts file
ansible-hosts in the current directory,
ping all hosts
export ANSIBLE_HOSTS=./ansible_hosts Save some time - ansible uses
environment variables extensivel
ansible -m ping all Same as before - but now ansible
leverages the env var to find the ansible
hosts file.
45. Demonstration
Command Description
ansible -m script test.sh all Here, we take a local script and execute
it across all of our hosts. Ansible takes
that script and delivers it via scp to the
hosts, executes it and captures the
output.
export ANSIBLE_HOSTS=./ansible_hosts Save some time - ansible uses
environment variables extensivel
ansible -m ping all Same as before - but now ansible
leverages the env var to find the ansible
hosts file.
