Free CCNA | Containers | Day 54 (part 2) | CCNA 200-301 Complete Course

welcome to Jeremy's it lab this is a complete course for the CCNA in this video we will cover a topic related to virtualization that is containers containers are similar to VMS virtual machines however there are some key differences that you must understand if you are interested in the field of devops you will have to learn containers

in depth for the CCNA however you only need to understand the very Basics here's what we'll cover in this video first we will review virtual machines containers are a similar technology to Virtual machines so it's important to understand both so we can compare them then we will look at containers you may have heard of Docker

before the most famous container engine available finally we will spend some time comparing virtual machines and containers to begin here's an example of apps running on a server without virtualization there is a single operating system for example Windows server or Red Hat Linux and on top of that OS all of the apps are running the

apps are not isolated a problem in one app could affect all of the other apps now you could isolate them by buying a separate physical server for each individual app but that is extremely cost inefficient virtual machines are a solution to this problem virtual machines VMS allow multiple operating systems to run on a

single physical server and then apps are installed on those operating systems a hypervisor is used to manage and allocate Hardware resources to each VM remember the VMS are all running on top of the same physical Hardware so they need a hypervisor to allocate those resources appro rately there are two main types of
