Published on

In modern IT «containers» is not simply a buzzword, this is a proven way of improving developers’ productivity and minimizing deployment costs. It allows to quickly create ready-to-run packaged applications; automate testing, integration and packaging. Containers are also widely using to support next generation cloud native applications based on microservices architectural pattern. The cloud application development and deployment paradigm is changing. Oracle gives you the cloud native container service and management platform for today’s evolving enterprise business.

  6. 6. Copyright © 2015, Oracle and/or its affiliates. All rights reserved. | What are Containers? Why use them? • A container is packaged as an entire runtime environment: the service/app plus all dependencies, libraries, & configuration files needed to run it • Portable across environments & lightweight (share the OS) An Open Technology to Build, Ship, and Run Distributed Applications Developers care because: • Quickly create ready-to-run packaged applications, low cost deployment and replay • Automate testing, integration, packaging • Reduce/eliminate platform compatibility issues (“It works in dev!”) • Support next gen applications (microservices) IT cares because: • Improve speed and frequency of releases, reliability of deployments • Makes app lifecycle efficient, consistent and repeatable – configure once, run many times • Eliminate environment inconsistencies between development, test, production • Improve production application resiliency and scale out/in on demand 7

  8. 8. Copyright © 2015, Oracle and/or its affiliates. All rights reserved. | Virtual Machines vs. Containers Virtual Machines ● Each virtual machine (VM) includes the app, the necessary binaries and libraries and an entire guest operating system Containers ● Containers include the app & all of its dependencies, but share the kernel with other containers. ● Run as an isolated process in userspace on the host OS ● Not tied to any specific infrastructure – containers run on any computer, infrastructure and cloud. VMs Containers 9

All rights reserved. | Key Container Use Cases 10 SOURCE: THE EVOLUTION OF THE MODERN SOFTWARE SUPPLY CHAIN, DOCKER SURVEY 2016 • Developer productivity a top use case today • Building out CI/CD pipelines – Consistent container image moves through pipeline – Preventing “it worked in dev” syndrome • Application modernization and portability are also key adoption drivers (Prem <-> cloud)

  11. 11. Copyright © 2015, Oracle and/or its affiliates. All rights reserved. | What is Docker? • It’s an improved, user-friendly Linux Container technology • Easy, human readable mechanism to build containers images based on recepies, aka Dockerfiles • Networking, memory, CPU, and file system boundaries for processes • Images for containers can be easily shared and extended – Container file system is layered; deltas used with copy-on-write • Extremely fast adoption by developers • Considered as a “lightweighter” virtualization technology • Runs on Linux, Windows, and Mac OS X – Soon on Solaris too, work being done by Oracle engineers An Open Platform to Build, Ship, and Run Distributed Applications 12
  12. 12. Copyright © 2015, Oracle and/or its affiliates. All rights reserved. | Isn’t a Container Just Like a VM? NO! Key differences Harder to over-subscribe physical hardware resources like CPU and memory Utilization Very easy to get to 100% consume physical hardware resources. Can easily move containers off of hosts when the hosts become too utilized Performance Heavy weight – must often go through abstraction layers to access physical hardware resources Lightweight – a container is just an operating system process. 100% native access to all physical hardware resources Must use configuration management tool to apply updates. Or must update every single gold image and then re-deploy Updates Can apply diffs to container images, or most often, the image is quickly rebuilt and container re-deployed Can be automated with 3rd-party tools (Chef/Puppet/etc), but takes a lot of time. Snapshots are bigger compared to Container images. Image Creation Same options as VMs + can also declaratively construct one using native, 1st class Dockerfile format. VMs Containers 13
  13. 13. Copyright © 2015, Oracle and/or its affiliates. All rights reserved. | Docker Architecture 101 • Docker Client talks to Docker Daemon • Client can run on a same machine or connect remotely • Docker Registries or Hubs hold images 14
  14. 14. Copyright © 2015, Oracle and/or its affiliates. All rights reserved. | Docker Images 15 • Containers have writeable file system • Recipes, the Dockerfiles, can be easily shared • Container as code • Images have layered file systems • Images can be extended • Images can be shared as binary files 15

  16. 16. Copyright © 2015, Oracle and/or its affiliates. All rights reserved. | • Developers care because: – Quickly create ready-to-run packaged applications – A clean, safe, hygienic, portable runtime environment – No missing/conflicting dependencies or packages – Each app runs in an isolated container – Automate testing, integration, packaging – Reduce/eliminate platform compatibility issues – Cheap/zero cost deployment, with instant replay and reset • Administrators care because: – Configure once, run many times – Makes app lifecycle efficient, consistent and repeatable – Eliminate environment inconsistencies between development, test, production – Supports segregation of duties – Improve speed and reliability of continuous integration and deployment – Lightweight containers address performance, costs, deployment and portability issues 17 Why IT Cares About Docker Containers?
  17. 17. Copyright © 2015, Oracle and/or its affiliates. All rights reserved. | What are the Benefits and Use Cases with Docker Containers? • Benefits – Using containers allows developers and sysadmins to isolate each application, providing specific dependencies for each application – Docker containers are tiny; they are designed to run a single application – Docker combines filesystem layers to improve re-use between containers – Cost savings on conventional virtualization due to greater density using containers • Spin off isolated infrastructures/processes within same VM. Better consumption of resources. • Use Cases – Application Deployment without “dependency hell” of multiple applications – Continuous Integration – Platform-as-a-Service (PaaS) – Development and Test Environment 18

Service A service is a template for how to run a container from a single image and associated Docker runtime information (e.g. mapped ports, storage volumes etc…) Stack A Stack is a template for how to run a multi-service (container) based application (e.g. an “ELK” stack). It is very similar (and compatible with) Docker Compose format. Deployment One or more running containers that have been created from deploying a Service or a Stack
  35. 35. Copyright © 2015, Oracle and/or its affiliates. All rights reserved. | • Hosts are Oracle Compute VMs managed by OCCS • Used for deploying services and stacks to run Docker containers • OCCS has one manager node, and a number of worker nodes (hosts) • Manager node orchestrates the deployment of Docker containers to the worker nodes • Worker node runs an OCCS agent to communicate Docker status to and from the manager node 36 Oracle Container Cloud: Hosts
