‫You're getting to one of the trickier bits
‫of running in the Cloud, which is how do you connect
‫inside of your servers
‫to perform some maintenance or action.
‫So for this, for Linux servers,
‫we can use SSH to do a secure shell into our servers.
‫So based on the operating system you have on your computer,
‫you have different ways of achieving it.
‫So I have separated Mac, Linux,
‫Windows before version 10 and Windows after version 10.
‫So the SSH is a command line interface utility
‫that can be used on Mac or Linux
‫as well as Windows over version 10.
‫Then if you have Windows less than version 10,
‫you can use something called putty.
‫Putty will exceed the exact same thing as SSH.
‫So when I say you should SSH, if you're on Windows,
‫you can use putty.
‫And putty is valid for any version of Windows.
‫They do the exact same thing, they allow you to
‫use the SSH protocol to connect into your EC2 instances.
‫And then finally, there's something new
‫called the EC2 Instance Connect,
‫which is going to use your web browser.
‫So not a terminal nut putty your web browser
‫to connect to your EC2 instance.
‫And I like it a lot because it is valid
‫for Mac, Linux, Windows, all versions.
‫The cool thing about EC2 Instance Connect is that it works,
‫but it only works for now with Amazon NX2
‫And this is why I've been using
‫Amazon NX2 in this tutorial.
‫So now what should you do?
‫If you are on Mac or Linux,
‫then please watch the SSH lecture on Mac/Linux.
‫If you're on Windows,
‫then you can either watch the Putty Lecture
‫or if you have Windows 10, then I have created an SSH
‫on Windows 10 lecture as well.
‫Regardless, I am going to personally use
‫in the future lectures, EC2 Instance Connect.
‫So if you wanna have a look and play with it,
‫I find it really simple.
‫You don't need to install anything
‫or use the command line interface
‫if you're not familiar with it.
‫So this could be very handy for all of you.
‫Nonetheless, SSH is in my experience
‫and I've taught hundreds of thousands of students
‫what caused the most troubles in this course.
‫So if you get a problem with SSH
‫we can re-watch the lecture, you may have missed something,
‫maybe a security group rule, maybe you command,
‫maybe a typo, I don't know you.
‫There's also a troubleshooting guide
‫that I've put together after these lectures so have a look.
‫I would recommend your try, EC2 Instance Connect
‫as well as sometimes fixes all problems.
‫And if none of these method works, sorry
‫if one method works, then you're good to go.
‫You don't need to have them all working.
‫If one works, you're good to go.
‫And if no method works, that's completely okay.
‫This course is just introductory
‫and he won't use SSH much and you'll be fine.
‫So that's it that just for the introduction.
‫Now find your right lecture and it will see you
‫in the next lecture.
