- 6. #PaychexIsIT • Paychex IT is: • Linux • Windows • Docker • Kubernetes • OpenShift • Azure • MongoDB • Kafka • RabbitMQ • Ansible • Cassandra • Redis • Puppet • OpenStack • MySQL • Microsoft SQL Server • Oracle
- 8. Containers • Lightweight • Portable • Fast Startup Times • Easy to Share • Immutable • Version Controlled • Secure
- 9. Kubernetes • Container Management and Orchestration • Open Source Project • 52k+ Github Stars • 18k+ Github Forks • Started by Google in 2014 • Backed by Multiple Vendors
- 10. OpenShift - Enterprise Kubernetes • Developer focused user experience • More Secure by design • Polished End User Experience Two Versions: • OpenShift – Backed by Red Hat Support • OKD – Upstream OpenSource Distribution
- 11. OpenShift @Paychex • In Production since 2015 • 20 Clusters accross two regions • 7 in-place upgrades • OpenShift hosted applications are responsible for moving well over $500 billion per year at Paychex
- 12. Deploying an Application • Deploying an Application leverages simple YAML files • Easy to Read • Declarative --- kind: "DeploymentConfig" apiVersion: "v1" metadata: name: "ose-eventforwarder" spec: template: metadata: labels: name: "ose-eventforwarder" spec: containers: name: "ose-eventforwarder" image: >- hub.docker.io/mdeneve/myapp:latest nodeSelector: type: "infra" replicas: 1 triggers: - type: "ConfigChange" strategy: type: "Rolling"
- 13. The Problem with Self Service
- 14. Developers are Clever! • Shadow IT • Tight Timelines • Need to innovate Now • “Just using it for testing” • Always becomes PROD Attribution: wocintechchat.com
- 15. Shadow IT
- 16. Tight Timelines
- 17. Need to Innovate Now
- 18. “Just using it for testing”
- 19. Shadow IT in Kubernetes is not Ideal The GOOD • Self Service • Quick to Spin Up • Quick to scale • Works for simple use cases The BAD • No easy way to Get DBAs involved • Black Box is NOT always a good thing • No control over data and where it is going • Database Sprawl
- 20. Databases in a Non-Persistent World
- 21. Persistent Storage in Kubernetes • Persistent Storage in Kubernetes is Hard • Complexity introduced when a container can run anywhere • Multiple Vendors, Multiple Solutions • No good ways to back up data • Lack of Enterprise Solutions • Long Term Archival / Retrieval is a challenge
- 22. Operators to the Rescue
- 23. Kubernetes Operators • A method of packaging, deploying and managing a Kubernetes application. • A Kubernetes application is • deployed on Kubernetes • managed using the Kubernetes native tooling • Think of Operators as the runtime that manages this type of application on Kubernetes.
- 24. MongoDB Operator to the Rescue
- 25. MongoDB Operator + MongoDB Ops Manager • Features added by Mongo • Deploy containers with MongoDB installed in standard patterns • Standalone • Replica Set • Sharded Cluster • All the best of MongoDB Enterprise / Ops Manager • Security • Backups/Restores • Easy Upgrades
- 26. MongoDB Ops Manager / Cloud Manager • Ops Manager/ Cloud Manager • MongoDB Provided Monitoring / Backup / Automation Solution • Accepts API calls from Operator to build MongoDB
- 27. Self Service, with Guide Rails • How does MongoDB Operator Help guide Devs? • All the benefits of containerization, plus • Security • Standardization • Same Deployment tools that are used in production • Easy remote management through Cloud Manager • "Push Button" • Easy for Database Engineers / DevOps / SRE teams to manage using current process
- 28. Deploying a MongoDB Server in OpenShift • Leverages YAML (just like everything else) • Declarative in Nature • Repeatable • Shareable --- apiVersion: mongodb.com/v1 kind: MongoDB metadata: name: myCluster namespace: myNameSpace spec: shardCount: 2 mongodsPerShardCount: 3 mongosCount: 2 configServerCount: 3 version: 4.0.6 project: myProject credentials: mySecret type: ShardedCluster persistent: true ...
- 29. Demo Time!
- 30. Demo Tasks? • Create Database in OpenShift – prerecorded • On the fly upgrade - live (but have recording) • Scale Mongo Cluster up - live (but have recording)
- 31. What Does the Future Hold?
- 32. MongoDB Operator @ Paychex • Sandbox Environment First • Used in Non-Prod/Development Envs • Automate data restores for test • Prod will remain Separate Infrastructure
- 33. Upcoming Features of the MongoDB Operator • Check out the 3 PM session in Nassau presented by Jason Mimick and Andrey Belik for the full Roadmap!
- 34. Summary • Save Devs from Themselves! • Simplify infrastructure • Keep ops teams involved (they exist for a reason!)
