- 4. #ibmedge Client Overview • Large Financial Services Organization • Currently running their .COM infrastructure of hundreds of Web Applications on Websphere on Power/AIX • Modernization of Applications a Strategic Priority: • Faster more Agile Development using modern tools and languages – SQL and No SQL DB’s – Containers – Java and Node.js Applications – Shift to a DevOps Methodology • Shift to a Microservices style Architecture to gain flexible and dynamic scalability to rapidly respond to changes in Website Patterns • Move to a Scale-Out Hardware Infrastructure • Chose Docker Containers on Linux on Power8 as the new Foundation • Partnered with IBM to design a Docker Cloud Environment 3
- 5. #ibmedge Client Container Cloud Requirements: • Hundreds of Web Applications • Support Thousands of Containers in a Production Environment • Utilize Open Source Components where possible • RHEL 7 LE (host) • Docker • Logging • Network Architecture • Storage Architecture • Security, Integration with LDAP/AD • HA • Backup • Dashboard/UI • Autoscaling 4
- 6. #ibmedge Cloud Native Docker Container Cloud • Supporting a new Cloud Native DevOps Docker model with a Scale Out Infrastructure • Modernizing Hundreds of Websphere Apps on Power providing services both to internal employees and external clients • Embracing Open Source Technologies like Docker, Mongo, Redis etc. • Cooperatively Integrating Open Source Components to deliver a complete Container Cloud Service • Production by 4Q16 Power Compute Node Cloud Approx 100’s of Systems Kubernetes Container Management Service Web Apps Web Apps Web Apps Web Apps Web Apps Web Apps Web Apps Open Source Tooling and SW Mongo Redis etc SQL DB’s Data Services User Applications (Internal and External) Self Service Developer Portal to Get Containers and Data Services … Docker Containers RedHat 7.1 LE Linux O/S & KVM SDNRegistry Operations Dashboard RegistryUI 5 Client Use Case
- 7. #ibmedge Open Source Options for Container Cloud Orchestration on Power Docker Swarm/Datacenter KubernetesMesos Docker Inc GoogleMesosphere • Strengths • Built-in to Docker 1.12 Engine • Easy to use for Small Clouds • Weaknesses • Full Docker DC not on Power Yet • Strengths • Good for Batch and Analytics • Lots of Apps in Catalog • Weaknesses • Less usage in Web Applications • Requires Marathon Framework for Web Apps • Strengths • Lots of Industry usage and experience for Web Apps • Synergy with Other parts of Client Business for X86 Container Mgmt • Weaknesses • Significant Integration of many components for Production Cloud 6

- 14. #ibmedge Integration with Client’s Enterprise LDAP Server 13 KeystoneExisting LDAP • Kubernetes uses namespaces to partition the cluster among multiple users • Three steps to Access: • Authentication • Authorization • Admission Control • Authorization defines what a Authenticated user can and can’t do: – AlwaysDeny: Used only for testing - AlwaysAllow: Used only for testing – ABAC: Attribute-based access control - Webhook: Calls out to an external authorization service via a REST call • ABAC based Authorization • Auth policies need to be created for every user and can be changed only by API server restart • Every user get's their own namespace • Read/write access to their own namespace • Read access to default (global) namespace • Kubernetes supports Openstack Keystone Component for Authentication • Keystone Provides LDAP/AD Integration
- 15. #ibmedge Overview of Monitoring Functionality Kubernetes monitoring is via CAdvisor 14 Kubernetes Cluster/CAdvisor Heapster InfluxDB SinkSource Grafana System View Pod View
- 16. #ibmedge Logging 15 • All kubernetes logs are in journald • Docker logging uses JSON • Splunk integration is being explored for integration into Client Logging tools • K8s metadata is part of docker container labels. • Log rotation is external and is handled separately
- 17. #ibmedge Container Cloud Lessons Learned • Identified Gaps in current state of Kubernetes • Lots of disparate parts to integrate, challenging to install/deploy • User interface is basic and not integrated across all components of the solution • Security is complicated and not complete, missing a UI • Resource Management incomplete • Integration with existing networking environment is challenging • Must fit into clients production networking environment and policies • Some client policies need to evolve – e.g. Live Internet Connection for building and maintaining Open Source • Now the hard part comes: Operations 24x7, High Availability, live rolling Upgrades, secure validation of Containers etc. 16
- 18. #ibmedge Client Use Case Container Cloud Summary • Kubernetes Container Cloud Environment based on Open Source Technologies Operational • System Test and Validation in process at Client • First Container Based Applications being piloted on the Cloud • Production Target on track for October Go Live 17
