Less Overhead
Virtual Machine Stack ContainersThe multiple advantages of containers
▪ Provides a consistent application platform for
hybrid cloud deployments
▪ Developers deliver a larger number of
application services from the same
hardware, reducing Capex and Opex costs.
▪ Reusable components enable developers to
deliver more timely, robust, and functional
applications and features
▪ Containerized applications require less staff
time for ongoing management of applications

Why Kubernetes?
▪ External Storage management
▪ Distributing secrets
▪ Application health checks
▪ Replicating application instances
▪ Horizontal Pod auto-scaling
▪ Load Balancing
▪ Rolling Updates
▪ Monitoring resources
▪ etc.
What can Kubernetes do?

Kubernetes Is The Clear Winner In Container Orchestration
Kubernetes has become the de facto
orchestration platform for running
cloud native workload.

Storage
▪ Containers are ephemeral—data is not
▪ There are no real stateless applications
▪ Data persistence requirements in the
enterprise have not changed
▪ Consumption of storage by containers
should be easy
TOP CHALLENGES SIGHTED BY FIRMS USING CLOUD CONTAINERS

▪ Released as an open source project in Dec 2016
▪ Natively integrates NetApp storage and services with
container platforms
▪ Supports a broad range of cross portfolio platforms and
services as well as all major container orchestrators

WORKLOADS
▪ Trident is an open-source storage provisioner and
orchestrator for the NetApp portfolio which takes
advantage of the StorageClass API object in
Kubernetes
▪ Trident enables applications which are provisioned and
managed using Kubernetes to consume storage
resources on demand, without having to worry about
the details.
▪ Admins can now:
▪ Create meta-classes of storage, such as Gold, Silver, and Bronze,
▪ Span multiple storage providers to seamlessly and transparently
provide homogenized storage features and capabilities
▪ All this regardless of the layout of the backing storage systems.

Kubernetes as a Service
© 2017 NetApp, Inc. All rights reserved.18

The stackpoint.io Kubernetes-as-a-service platform combined with
NetApp’s Cloud Data Services creates a complete DevOps solution,
so customers can focus on innovation, not administration
Creating the Industry’s First Complete Multi-Cloud Kubernetes Platform
NetApp acquires StackPointCloud

NetApp Kubernetes Service
▪ What is StackPointCloud?
▪ StackPointCloud is a multi-cloud Kubernetes Control Plane that delivers true Kubernetes
across all of the major public clouds and bare metal.
▪ What does this mean?
▪ Developers and IT teams can spend time writing more code and less time on provisioning,
managing and upgrading Kubernetes clusters across clouds.
▪ With just a few clicks, you can go in and deploy a Kubernetes Cluster in AWS. You can
then do the same in Azure, GCP, or DigitalOcean without taking the lengthy steps to get
the cluster up and running, and instead focus on innovation instead of operations.

A Brief Overview
What are Containers?
© 2018 NetApp, Inc. All rights reserved. --- NETAPP CONFIDENTIAL ---36

Containers Are Not Virtual Machines
• Virtual Machines
• VMs are heavy, being composed of virtual
hardware, a full OS, and the application,
including dependencies
• Containers
• A container is just the application and its
dependencies
• It runs as an isolated process in user space on
the host OS
Images: Docker, https://www.docker.com

Docker Made Containers Accessible
• Docker abstracts the creation and
management of containers
• Containers for mortals!
• Define application components:
containers, storage, and networking
• The Docker portfolio enables management
for containerized microservice applications
• Docker Engine
• Docker Registry
• Docker Swarm
• Docker Data Center
# start a container
$ docker run mysql:latest
# map a port
$ docker run –p 3306:3306 mysql:latest
# map a host directory
$ docker run
–v /mysql/data:/var/lib/mysql
mysql:latest

• Volumes decouple the data from the
container
• Exist beyond the lifespan of the container
• Local volumes are managed by the
container engine (e.g. Docker)
• External volumes
• Can be a host file/directory
• Or, storage mounted from another device
• Docker Volume Plugin paradigm enables
users to consume non-local storage
devices
Persisting Containerized Applications

Container Orchestrators
• Containerized application deployment
• Service discovery
• Health checking / high availability
• Scale up/down
• Load balancing
• Authentication / authorization
• Secrets management
• Logging
• Monitoring
Kubernetes
Marathon
Swarm

• Monolithic applications
• Hard to update - single massive code base
• Single dimension of scalability
• Waterfall development practices
• Static, linear phases
• Requirements
• Analysis
• Design
• Code
• Test
• Deploy
Applications Are Hard
Image: https://martinfowler.com/articles/microservices.html

• Service-Oriented Architecture
• New term = microservices
• Each component is independently developed and
scaled
• Everything is a platform
• DevOps
• Continuous Integration – Finding and fixing bugs
faster
• Continuous Deployment – Releasing faster
Simplify the Problem
Image: https://martinfowler.com/articles/microservices.html

Virtualization as a First Step
Standardized, automated, efficient
• Virtual machines are easier than physical
• Lighter weight, deploy quickly
• Decouple the OS from hardware
• Declarative configuration management
• Ansible, Puppet, Chef, Salt, PowerShell DSC
• Remove manual process from deployment and
configuration operations
• AWS and OpenStack made self-service
mainstream

Containers Make Everything Better
• Lightweight, fast, portable
• A lot like Object Oriented Programming
• Inheritance, Encapsulation, Abstraction
• Now consumable by mortals!
• DevOps + Microservices + Containers =
Maintainability and Scalability
• Containers decouple the app from the OS

The Containers Ecosystem

NetApp for Containers

Docker
• Docker Engine
• Docker Swarm Mode
• Docker Enterprise Edition
The one everyone knows

Kubernetes
• Kubernetes
• Open source project managed by the CNCF
• Products built on Kubernetes – open source core, proprietary value-add
• Docker
• Red Hat OpenShift
• IBM Cloud Private
• CoreOS Tectonic (now owned by Red Hat, going away)
• Rancher
• Pivotal Container Service
• Amazon EKS, Azure AKS, Google GKE
The other one everyone knows

Engines vs Orchestrators
• Engines instantiate individual containers
• Start the process and create the namespace around it
• Attach network, storage, and other resources
• Manage cgroups
• Examples:
• Docker, rkt, lxc, lxd
• Orchestrators orchestrate container deployments across many hosts
• Multiple related containers which usually need to communicate with each other
• Decides how to allocate physical/virtual resources to container instances
• Rely on container engines to instantiate the container instance
• Examples:
• Kubernetes, Swarm, Marathon
