Talk Context: What is a PaaS? •  Platform as a Service.

•  Is Docker a PaaS?

•  Industry Definitions.

6

Platform as a Service (PaaS). The capability provided to the consumer is to deploy onto the cloud infrastructure consumer-created or acquired applications created using programming languages, libraries, services, and tools supported by the provider. The consumer does not manage or control the underlying cloud infrastructure including network, servers, operating systems, or storage, but has control over the deployed applications and possibly configuration settings for the application-hosting environment. http://csrc.nist.gov/publications/nistpubs/800-145/SP800-145.pdf

Advantages of PaaS? Developer

•  Features for ‘free’, reduces per-product load.

●  Automated deployments and scaling.

●  Middleware as a service.

●  Logging and monitoring as a service.

●  Load balancing & HA.

●  Zero downtime upgrades.

●  Portability.

•  Focus on developing software.

•  Enforces scalable coding practices.

•  Guarantees cross-environment consistency.

•  Reduce cloud-burst complexity.

•  Faster time to production.

Advantages of PaaS? Operator

•  Designed to be horizontally scaled

•  Repeatable, easy to use orchestration.

•  Environment consistency

•  Excellent demarcation (platform/code)

•  Auditable, zero downtime upgrades (of the PaaS itself)

•  Gives power to development teams without reducing visibility…

●  Access production logs

●  Control their own production gates

●  Zero cost, consistent dev environments

•  Reduction of operator bottleneck. …. Faster time to Production

Advantages of PaaS? Business

•  Faster innovation, Fast IT

•  Growing tooling expectations from developers.

•  Industry wants more than IaaS from SP’s.

•  Shape an emerging technology stack.

•  Support DevOPS / Agile for your customers and/or staff.

•  Give customers what they want. Spend less on doing it.

PaaS Solutions / Products

14

© 2015 Cisco and/or its affiliates. All rights reserved. Cisco Public Presentation ID

CloudFoundry OpenShift Mesos •  Pivotal spun out from

VMWare. GE, EMC

•  Open Source and Commercial Versions.

•  Data Services Brokers. •  Commercial version

can deploy data services alongside w/partner products.

•  Large Community.

•  Scheduler is ‘diego’, part of the project.

•  Building on the solid reputation of RedHat

•  OpenSource (origin) and Commercial Versions

•  OpenShift V3 is a complete redesign.

•  Data Services in containers.

•  User experience layer on top of Kubernetes (Google-developed Docker scheduler)

•  Not a PaaS

•  Mesos is a Scheduler across multiple hosts.

•  Could be used (technically) instead of Diego / K8’s to underpin the higher level user experience provided by OpenShift or CloudFoundry.

•  Mentioned because it’s gaining traction.

The Community… •  ActiveState Stackato.

•  Based on OpenSource CloudFoundry.

•  API Compatible.

•  Deployment Differences.

•  Kubernetes (OpenSource)

•  Doesn’t provide the OpenShift user experience.

•  Scheduler vs ‘PaaS’

… There are none

•  Words of Warning •  Data Services •  Scale out + Codebase •  Testing •  Following the ‘PaaS Rules’

•  Can I SSH into my container to install XYZ

30

•  Cattle Not Pets. •  One size, sadly does not fit all.

•  There will be outliers. •  Doesn’t use an an excuse.
