Cloud Foundry Platform Operations - CF Summit 2015cornelia davis
In this session Cornelia will share lessons learned from a month spent on a team that operates a production instance of Cloud Foundry. From her first morning addressing a prod incident, through building ops dashboards, documenting how a crashed micro-bosh is recovered, and prod deploys, she will share lessons on the value of declarative, immutable infrastructure, cloud-native application design and proper abstractions. Tried and true practices such as checklists and jumpboxes remain, while new ones such as primetime deploys and even live experimentation in prod emerge. The punchline? Even as an ops novice, she was immediately productive. In this session Cornelia will present specific techniques for using BOSH, system metrics and logging, dashboards, alerting systems and more to manage your CF deployment.
Unlock your VMWare Investment with Pivotal Cloud Foundry (VMworld 2014)VMware Tanzu
Presented by Cornelia Davis - Platform Engineer, Cloud Foundry, Pivotal
You might have heard that software is eating the world; in every industry enterprises are being challenged to bring software to their consumers faster, more frequently and with insanely great user experiences. Pivotal Cloud Foundry, the leading enterprise Platform as a Service (PaaS) that is powered by Cloud Foundry, is designed to remove friction from the traditional application lifecycle, from dev all the way through production. At the core it exposes application and services “dial tone”, rather than infrastructure “dial tone”, scoping a broad set of capabilities such as autoscaling, dynamic routing, logging, monitoring, health management, and more, around the application. Pivotal Cloud Foundry itself depends on the infrastructure “dial tone” that is brilliantly provided by vSphere or vCHS.
In this session we’ll start with the industry drivers for PaaS, explain how it leverages your existing vSphere or vCHS investment, and then dive into the details of what Pivotal Cloud Foundry brings to the enterprise developer and operator. Light on slides and heavy on demo, you’ll come away with a solid understanding of how Pivotal CF can revolutionize they way your enterprise develops, delivers and manages software.
Cloudfoundry is the open platform as a service providing a faster and easier way to build, test, deploy and scale applications.Deploy & Scale in seconds on your choice of clouds.

Colorado Cloud Foundry Meetup
May 19, 2015
Lattice and Docker with Cornelia Davis
Starting with a comparison of the current core runtime of the Cloud Foundry Elastic Runtime, to the new Diego rewrite, we take a tour through how linux containers can run a variety of image formats, including Docker. We talk about one way that you can get the Diego functionality in Lattice, a container scheduler that runs on a laptop or as a cluster in the cloud. We talk about ways of creating container images including Cloud Rocker and we draw it all together with a bunch of demos.
Abstract from the meetup:
What is Lattice (www.lattice.cf)?
Lattice is an open source project for running containerized workloads on a cluster. A Lattice cluster is comprised of a number of Lattice Cells (VMs that run containers) and a Lattice Coordinator that monitors the Cells.
Lattice includes built-in http load-balancing, a cluster scheduler, log aggregation with log streaming and health management.
Lattice containers are described as long-running processes or temporary tasks. Lattice includes support for Linux Containers expressed either as Docker Images or by composing applications as binary code on top of a root file system. Lattice's container pluggability will enable other backends such as Windows or Rocket in the future.
At this joint NYC Cloud Foundry and NY PHP meetup, we'll discuss the shift to Platform-as-a-Service and what it means for PHP development on the cloud.
First, we'll take a look at the "traditional" cloud Infrastructure-as-a-Service (virtual servers and disks) model and describe how Platform-as-a-Service builds upon it to provide the runtimes and data services for hosting PHP applications.
We'll then demonstrate how a PHP developer can use buildpacks and services within a Cloud Foundry PaaS to deploy scalable and resilient apps to his or her cloud of choice.
Along the way we'll compare the variety of buildpacks available to PHP developers, show techniques for binding to services, and highlight best practices for creating born-on-the-cloud apps based on a microservices architecture.
Special thanks to Dan Mikusa for helping with the buildpack comparison.
PHP developers: Please give all three build packs a try. Provide your feedback and submit pull requests on GitHub.
Cloud Foundry Introduction (w Demo) at Silicon Valley Code Campcornelia davis
Silicon Valley Code Camp, The Self-healing Elastic Runtime that is Cloud Foundry.
While we did mostly demo in this session, these slides set a bit of context first. Also includes the four levels of HA in Cloud Foundry.
Cloud Foundry and Microservices: A Mutualistic Symbiotic RelationshipMatt Stine
As delivered to the Cloud Foundry Summit 2014 in San Francisco, CA:
With businesses built around software now disrupting multiple industries that appeared to have stable leaders, the need has emerged for enterprises to create "software factories" built around the following principles:
* Streaming customer feedback directly into rapid, iterative cycles of application development
* Horizontally scaling applications to meet user demand
* Compatibility with an enormous diversity of clients, with mobility (smartphones, tablets, etc.) taking the lead
* Continuous delivery of value, shrinking the cycle time from concept to cash
Infrastructure has taken the lead in adapting to meet these needs with the move to the cloud, and Platform as a Service (PaaS) has raised the level of abstraction to a focus on an ecosystem of applications and services. However, most applications are still developed as if we're living in the previous generation of both business and infrastructure: the monolithic application. Microservices - small, loosely coupled applications that follow the Unix philosophy of "doing one thing well" - represent the application development side of enabling rapid, iterative development, horizontal scale, polyglot clients, and continuous delivery. They also enable us to scale application development and eliminate long term commitments to a single technology stack.
While microservices are simple, they are certainly not easy. It's recently been said that "microservices are not a free lunch". Interestingly enough, if you look at the concerns expressed here about microservices, you'll find that they are exactly the challenges that a PaaS is intended to address. So while microservices do not necessarily imply cloud (and vice versa), there is in fact a symbiotic relationship between the two, with each approach somehow compensating for the limitations of the other, much like the practices of eXtreme Programming.

KFServing - Serverless Model InferencingAnimesh Singh
Deep dive into KFServing: Serverless Model Inferencing Platform built on top of KNative and Istio. Part of the Kubeflow project, and deployed in production across organizations.
End to end Machine Learning using Kubeflow - Build, Train, Deploy and ManageAnimesh Singh
With the breadth of sheer functionalities which need to be addressed in the Machine Learning world around building, training, serving and managing models, getting it done in a consistent, composable, portable, and scalable manner is hard. The Kubernetes framework is well suited to address these issues, which is why it's a great foundation for deploying ML workloads. Kubeflow is designed to take advantage of these benefits. In this talk, we are going to address how to make it easy for everyone to develop, deploy, and manage portable, scalable ML everywhere and support the full lifecycle Machine Learning using open source technologies like Kubeflow, Tensorflow, PyTorch,Tekton, Knative, Istio and others. We are going to discuss how to enable distributed training of models, model serving, canary rollouts, drift detection, model explainability, metadata management, pipelines and others. Additionally we will discuss Watson productization in progress based on Kubeflow Pipelines and Tekton, and point to Kubeflow Dojo materials and follow-on workshops.
Defend against adversarial AI using Adversarial Robustness Toolbox Animesh Singh
With great power comes great responsibility. Adversarial examples in AI pose an asymmetrical challenge with respect to attackers and defenders. AI developers must be empowered to defend deep neural networks against adversarial attacks and allow rapid crafting and analysis of attack and defense methods for machine learning models.
Animesh Singh and Tommy Li explain how to implement state-of-the-art methods for attacking and defending classifiers using the open source Adversarial Robustness Toolbox. The library provides AI developers with interfaces that support the composition of comprehensive defense systems using individual methods as building blocks. Animesh and Tommy then demonstrate how to use a Jupyter notebook to leverage attack methods from the Adversarial Robustness Toolbox (ART) into a model training pipeline. This notebook trains a CNN model on the Fashion MNIST dataset, and the generated adversarial samples are used to evaluate the robustness of the trained model.
Advanced Model Inferencing leveraging Kubeflow Serving, KNative and IstioAnimesh Singh
Model Inferencing use cases are becoming a requirement for models moving into the next phase of production deployments. More and more users are now encountering use cases around canary deployments, scale-to-zero or serverless characteristics. And then there are also advanced use cases coming around model explainability, including A/B tests, ensemble models, multi-armed bandits, etc.
In this talk, the speakers are going to detail how to handle these use cases using Kubeflow Serving and the native Kubernetes stack which is Istio and Knative. Knative and Istio help with autoscaling, scale-to-zero, canary deployments to be implemented, and scenarios where traffic is optimized to the best performing models. This can be combined with KNative eventing, Istio observability stack, KFServing Transformer to handle pre/post-processing and payload logging which consequentially can enable drift and outlier detection to be deployed. We will demonstrate where currently KFServing is, and where it's heading towards.
Hybrid Cloud, Kubeflow and Tensorflow Extended [TFX]Animesh Singh
Kubeflow Pipelines and TensorFlow Extended (TFX) together is end-to-end platform for deploying production ML pipelines. It provides a configuration framework and shared libraries to integrate common components needed to define, launch, and monitor your machine learning system. In this talk we describe how how to run TFX in hybrid cloud environments.
Trusted, Transparent and Fair AI using Open SourceAnimesh Singh
Fairness, robustness, and explainability in AI are some of the key cornerstones of trustworthy AI. Through its open source projects, IBM and IBM Research bring together the developer, data science and research community to accelerate the pace of innovation and instrument trust into AI.
Microservices, Kubernetes and Istio - A Great Fit!Animesh Singh
Microservices and containers are now influencing application design and deployment patterns. Sixty percent of all new applications will use cloud-enabled continuous delivery microservice architectures and containers. Service discovery, registration, and routing are fundamental tenets of microservices. Kubernetes provides a platform for running microservices. Kubernetes can be used to automate the deployment of Microservices and leverage features such as Kube-DNS, Config Maps, and Ingress service for managing those microservices. This configuration works fine for deployments up to a certain size. However, with complex deployments consisting of a large fleet of microservices, additional features are required to augment Kubernetes.
How to build a Distributed Serverless Polyglot Microservices IoT Platform us...Animesh Singh
When people aren't talking about VMs and containers, they're talking about serverless architecture. Serverless is about no maintenance. It means you are not worried about low-level infrastructural and operational details. An event-driven serverless platform is a great use case for IoT.
In this session at @ThingsExpo, Animesh Singh, an STSM and Lead for IBM Cloud Platform and Infrastructure, detailed how to build a distributed serverless, polyglot, microservices framework using open source technologies like:
OpenWhisk: Open source distributed compute service to execute application logic in response to events
Docker: To run event driven actions 6. Ansible and BOSH: to deploy the serverless platform
MQTT: Messaging protocol for IoT
Node-RED: Tool to wire IoT together
Consul: Tool for service discovery and configuration. Consul is distributed, highly available, and extremely scalable.
Kafka: A high-throughput distributed messaging system.
StatsD/ELK/Graphite: For statistics, monitoring and logging
How to build an event-driven, polyglot serverless microservices framework on ...Animesh Singh
Serverless cloud platforms are a major trend in 2016. Following on from Amazon’s Lambda service, released last year, this year has seen Google, IBM and Microsoft all launch their own solutions. Serverless microservices are executed on-demand, in milliseconds, rather than having to sit idle waiting. Users pay only for the raw computation time used.
In this talk detail how to build a distributed serverless, event-driven, microservices framework on OpenStack
As a Service: Cloud Foundry on OpenStack - Lessons LearntAnimesh Singh
According to OpenStack users survey, Cloud Foundry is the 2nd most popular workload on OpenStack. You want to deploy Cloud Foundry on OpenStack or already have. What's next?
Cloud Foundry continues to evolve with revolutionary changes, e.g move from bosh-micro to bosh-init, using the new eCPI, move to Diego etc.
Same with OpenStack, e.g changes from Keystone v2 to v3, from Liberty to Mitaka, network plugins changes etc. Both IaaS and PaaS layers are changing frequently. How do you do in-place updates/upgrades/operational tasks without impacting user experience at both the layers?
In this talk will discuss our lessons learnt operating hybrid Cloud Foundry deployments on top of OpenStack over the last two years and how we used underlying technologies to seamlessly operate them

"Impact of front-end architecture on development cost", Viktor TurskyiFwdays
I have heard many times that architecture is not important for the front-end. Also, many times I have seen how developers implement features on the front-end just following the standard rules for a framework and think that this is enough to successfully launch the project, and then the project fails. How to prevent this and what approach to choose? I have launched dozens of complex projects and during the talk we will analyze which approaches have worked for me and which have not.

11. Creating Custom Frameworks / Buildpacks
•Buildpacks are a convenient way of packaging framework and/or runtime support for your application.
Standard buildpacks available Ruby (Rails, Rack and Sinatra),Java (Java_web, Spring, Grails and Play),Node
• Custom Buildpacks: The buildpack structure is pretty straight forward. A buildpack repository contains
three main scripts, situated in a folder named 'bin'
bin/detect
This script is used to determine whether to apply this buildpack to an application or not. The script is
called with one argument, the build directory for the application.
bin/compile
The compile script is responsible for actually building the droplet that will be run by the DEA.
The script is run with two arguments, the build directory for the application and the cache
directory, which is a location the buildpack can use to store assets during the build process.bin/release
The release script provides feedback metadata back to Cloud Foundry, it's
run with one argument, the build location of the application.
The expected format for the return data is YAML
12. DEAs and Warden Containers
•DEAs: The Droplet Execution Agent (DEA) is written in Ruby and managing an application instance's life cycle.
It can be instructed by the Cloud Controller to start and stop application instances. It keeps track of all started
instances, and periodically broadcasts messages about their state over NATS (meant to be picked up by the
Health Manager). The DEA depends on Warden to run application instances.
•Warden: Warden is a framework that allows you to spawn containers in seconds and programmatically control
resource isolation (memory, bandwidth, disk), mounts, processes and other things using APIs.
Isolation is achieved by namespacing kernel resources that would otherwise be shared. The intended level of
isolation is set such that multiple containers present on the same host should not be aware of each others
presence Resource control is done by using Linux Control Groups. Every container is placed in its own control
group At its core warden is a Ruby daemon. Currently tested and verified for Ubuntu and CentOS, though
experimental version exists for Windows.

13. Organization and spaces are
two new concept in NG
Organizations: An organization is the top-most
meta object within the Cloud Foundry
infrastructure. Spaces: An organization can
contain multiple spaces. The defaults for a
standard Cloud Foundry install
are development, test, and production.
Domains: A domain is a domain-name like
acme.com or foo.net. Routes: A route, based on
a domain with an optional host as a prefix, may
be associated with one or more applications.
Organization/Spaces/Users
