What are containers?

@DavidGiard

ContainersA new approach to build, ship, deploy, and instantiate applications

Physical

Applications traditionally built and deployed onto physical systems with 1:1 relationshipNew applications often required new physical systems for isolation of resources

Higher consolidation ratios and better utilizationFaster app deployment than in a traditional, physical environmentApps deployed into VMs with high compatibility successApps benefited from key VM features i.e., live migration, HA

Physical/VirtualKey benefitsFurther accelerate of app deploymentReduce effort to deploy appsStreamline development and testingLower costs associated with app deploymentIncrease server consolidation

Package and run apps withincontainers

Virtual

@DavidGiard

Why containers?Applications are fueling innovation in today’s cloud-mobile world

Developers• Containers unlock ultimate productivity and freedom• Enable ‘write-once, run-anywhere’ apps• Can be deployed as multi-tier distributed apps in

IaaS/PaaS models • Containers offers powerful abstraction for

microservices

Operations• Enhances familiar IT deployment models• Provide standardized environments for

development, QA, and production teams

• Abstract differences in OS distributions and underlying infrastructure

• Higher utilization and compute density• Rapid scale-up and scale-down in response to

changing business needs

DevOps• Integrate people, process, and tools

for an optimized app development process

• Operations focus on standardized infrastructure

• Developers focus on building, deploying, and testing apps

ContainersIsolated runtime environment for hosted applicationsDependenciesEvery application has its own dependencies which includes both software (services, libraries) and hardware (CPU, memory, storage)

VirtualizationContainer engine is a light weight virtualization mechanism which isolates these dependencies per each application by packaging them into virtual containers

Shared host OSContainer runs as an isolated process in user space on the host OS, sharing the kernel with other containers

FlexibleDifferences in underlying OS and infrastructure are abstracted away, streamlining ‘deploy anywhere’ approach

FastContainers can be created almost instantly, enabling rapid scale-up and scale-down in response to changes in demand

@DavidGiard

FlexibleVMs can be migrated to other hosts to balance resource usage and for host maintenance, without downtime

SecureHigh levels of resource and security isolation for key virtualized workloads

ContainersHow do they differ from virtual machines?

DependenciesEach virtualized app includes the app itself, required binaries and libraries and a guest OS, which may consist of multiple GB of data

Independent OSEach VM can have a different OS from other VMs, along with a different OS to the host itself

Integrating with Docker

@DavidGiard

Run anywhere

Docker integrationJoint strategic investments to drive containers forwardDockerAn open source engine that automates the deployment of any application as a portable, self-sufficient container that can run almost anywhere

PartnershipEnable the Docker client to manage multi-container applications using both Linux and Windows containers, regardless of the hosting environment or cloud provider

Development with Containers

@DavidGiardLocal Repository

Development process using containers

Central Repository





Central Repository


Developers can choose desired application frameworks and pull them locally from central repositories




Central Repository


Developers can choose desired application frameworks and pull them locally from central repositories

Required dependencies are automatically identified and pulled locally




Developers use the same programming languages and environments they are accustomed to

Central Repository


using System;class Program{ static void Main() {

}}




Applications are compiled and assembled in the same way developers are accustomed to
