Everybody loves containers

A standard way to package an application and all its dependencies so that it can be moved

between environments and run without changes.

Containers work by isolating the differences

between applications inside the container so that everything outside the container can be

standardized.

Container History Lesson

Introduction to Docker

• Open Software – Launched March 2013 – 2.0+ billion downloads of Docker images

• Open Contribution – 2000+ contributors – #2 most popular project – 185 community meet-up groups in 58 countries

• Open Design – Contributors include IBM, Red Hat, Google,

Microsoft, VMware, AWS, Rackspace, and others

• Open Governance – 12 member governance advisory board selected by

the community

Enabling application development efficiency, making deployment more efficient, eliminating vendor ‘lock-in’ with true portability

Docker Mission Docker is an open platform for building distributed applications for developers and system administrators.

Docker Basics – A Shipping Container for Code Image • A read-only snapshot of a container stored in Docker Hub to be used as a template for building

containers

Container • The standard unit in which the application service resides or transported Docker Hub/Registry • Available in SaaS or Enterprise to deploy anywhere you choose • Stores, distributes and shares container images Docker Engine • A program that creates, ships and runs application containers • Runs on any physical and virtual machine or server locally, in private or public cloud • Client communicates with Engine to execute commands

SaaS Enterprise

Docker Containers A technical view into the shared and layered file systems technology

• Docker uses a copy-on-write (union) filesystem

• New files(& edits) are only visible to current/above layers

• Layers allow for reuse • More containers per host

• Faster start-up/download time – base layers are "cached"

• Images • Tarball of layers (each layer is a tarball)

Why Customers are Interested in Containers

Ship More Software

App Portability

Resource Efficiency

Accelerate development, CI and CD pipelines by eliminating headaches of setting up environments and dealing with differences between environments. On average, Docker users ship software 7X more frequently1.

Lightweight containers run on a single machine and share the same OS kernel while images are layered file systems sharing common files to make efficient use of RAM and disk and start instantly.

Isolated containers package the application, dependencies and configurations together. These containers can then seamlessly move across environments and infrastructures.

Containers are a critical foundation for distributed apps in Hybrid Clouds

Microservices

The Hype

Feb 26, 2… Sep 1, 2013 Mar 8, 2016 Sep 11, 2016

Interest over time

68% of organizations are using or investigating microservices.

NGINX survey, 3/29/16

Businesses using microservices report a 75% drop in development lead times. Techcrunch, 1/23/16

75% 68%

The Motivation

Being competitive requires:

– Rapid delivery – Leveraging public cloud – Simple, rapid scaling

Traditional monoliths fail: – Changes are coupled

– Not designed for public cloud – Scaling is complex

The Definition

An engineering approach focused on decomposing an application into single-function modules with well- defined interfaces which are independently deployed and operated by a small team who owns the entire lifecycle of the service.

Microservices is about people

Microservices accelerate delivery by minimizing communication and coordination between people while reducing the scope and risk of change.
