The document discusses the concept of Platform as a Service (PaaS) provided by Cisco, emphasizing its benefits for developers, operators, and businesses through faster development, automated deployment, and scalability. It contrasts PaaS with container solutions like Docker, highlighting that while containers are crucial, they do not encompass the full scope of PaaS. The presentation also covers various PaaS solutions, deployment strategies, and future innovations in the PaaS landscape within Cisco's Intercloud services.

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.

Containers are a building block of every PaaS, but not the whole story.

11. © 2015 Cisco and/or its affiliates. All rights reserved. Cisco PublicPresentation ID
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.

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

• Cattle Not Pets.
• One size, sadly does not fit all.
• There will be outliers.
• Doesn’t use an an excuse.
