cloud computing is a term that refers to the ability to access everything remotely on the internet instead of locally on your devices everything you use like mail music and video streaming apps all have data that needs to be stored somewhere that somewhere is really just a Global Network of computer clusters and servers but the network of computer clusters doesn't quite have a ring to it so we'll just call it the cloud here's a relatable example to help you understand all of you are watching YouTube on some type of device with most of you on your
phones and computers but even someone tablets and TVs how many videos have you watched today and more importantly how many of my videos have you watched if you've watched them all first of all thank you but secondly this means you've watched about four gigabytes worth of content without cloud computing you would have to store these four gigabytes on your local device just to be able to watch them combine that with everything else you watch on YouTube and your device would be full in no time thankfully YouTube has cloud-based storage which means that my four gigabytes
of videos are stored somewhere far away in a large and expensive cluster of computers and put on display to the internet YouTube stores these videos so you don't have to cloud computing isn't a single piece of technology instead it's a system which is made up of three main types of services software platform and infrastructure software as a service represents online software applications that manage every service for you Dropbox is a great example of this all you have to do is purchase the software and you can start uploading to the cloud Dropbox handles everything platform as
a service providers manage pretty much everything but allow you to handle the applications and data this makes it primarily used as a platform for software development Heroku is the perfect example here developers are able to host their applications on the cloud without need to worry about anything except the development of the application lastly infrastructure as a service is used when you want more flexibility than platform as a service and want to handle the middleware and operating system components as well Some Cloud providers only offer one of these three services but larger Cloud Computing Services like
Google Cloud Amazon web services and Microsoft Azure offer options for all three types of services this has been cloud computing in two minutes if you want more than two minutes please like subscribe and leave a comment for what you'd like to see next see you in the next video
