  8. What are Docker Containers? Docker vs VM www.edureka.co/devops DevOps Certification Training

  9. Types of Containers Copyright © 2018, edureka and/or its affiliates. All rights reserved.

  10. Types of Containers Linux Containers (LXC) Docker • To build single-application LXC containers. More portable and flexible to use. Later morphed into its own container runtime environment. At a high level, Docker is a Linux utility that can efficiently create, ship, and run containers. • • Commonly known as LXC. • It is a Linux operating system level virtualization method for running multiple isolated Linux systems on a single host. • • Docker vs VM www.edureka.co/devops DevOps Certification Training

  11. Benefits of Containers Quicker Spinning Less Code Security Updates Reduced Size Of Snapshots Reduced IT Management Resources Docker vs VM www.edureka.co/devops DevOps Certification Training

  13. Major Differences Copyright © 2018, edureka and/or its affiliates. All rights reserved.

  14. Major Differences ✓ Containers: ✓ Hosted on a single physical server ✓ Suitable for running multiple applications over a single OS kernel ✓ Virtual machines: ✓ Have a host OS and individual guest OS inside each VM ✓ Required for applications or services OS Support Docker vs VM www.edureka.co/devops DevOps Certification Training

  15. Major Differences ✓ Containers: ✓ Hosted on a single physical server ✓ Suitable for running multiple applications over a single OS kernel ✓ Virtual machines: ✓ Have a host OS and individual guest OS inside each VM ✓ Required for applications or services OS Support ✓ Docker: Has access to the kernel subsystems ✓ VM: Provides root access to applications ✓ Own kernel and security features Security Docker vs VM www.edureka.co/devops DevOps Certification Training

  16. Major Differences ✓ Docker: ✓ Containers are self-contained packages that can run the required application ✓ Light-weight architecture ✓ For development purposes Docker containers are the ideal choice ✓ VM: ✓ Are isolated server instances with their own OS Portability Docker vs VM www.edureka.co/devops DevOps Certification Training

  17. Major Differences ✓ Docker: ✓ Containers are self-contained packages that can run the required application ✓ Light-weight architecture ✓ For development purposes Docker containers are the ideal choice ✓ VM: ✓ Are isolated server instances with their own OS Portability ✓ Docker: ✓ Light-weight architecture and start up very fast compared to VM, ✓ Resource usage also varies among the two ✓ CPU, memory, I/O, etc. usage varies with the load ✓ VM: ✓ No need to allocate resources permanently to containers Performance ✓ Has to load an entire OS to start Docker vs VM www.edureka.co/devops DevOps Certification Training

  19. How PayPal Bank Uses Docker and VM CHALLENGES Provides Online Payment Solutions ✓ Account Balances ✓ Bank Accounts ✓ Credit Cards Improving Security Cost Efficient Modernize Data Centre TECHNOLOGY USED ADVANTAGES Reduce No. of VM Cost Efficient Productivity Enterprise Grade Security Reference : https://www.docker.com/customers/paypal-uses-docker-containerize-existing-apps-save-money-and-boost-security Docker vs VM www.edureka.co/devops DevOps Certification Training

  20. Session In A Minute Virtual Machines Docker Containers Hardware level process isolation OS level process isolation VM offers complete isolation of applications from host OS Docker containers can share some resources with host OS Each VM has separate OS Each docker container can share OS resources Boosts in minutes Boosts in seconds More resource usage Less resource usage Pre-configured VMs are hard to find and manage Pre-built docker containers for home server apps already available Customizing pre-configured VMs require work Building a custom setup with containers is easy VMs are typically bigger in size as they contain whole OS underneath Docker containers are small in size with only docker engine over the host OS VMs can be easily moved to a new host OS Containers are destroyed and recreated rather than moving Creating VMs take relatively long time Docker containers can be created in seconds Virtualized Apps are harder to find and it takes more time to install and run them Containerized apps such as Sonarr, CouchPotatoa etc. can be found and installed easily within minutes.
