Your VMs will persist until the end of the course. = AWS cost monitoring = * You are responsible for your AWS usage. Normally using resources from AWS costs money. In an AWS Educate Learner Lab you get a 100$ credit which will be more than enough to cover all your resources until the end of the course.** Take this opportunity during the course to learn what costs how much money, and make sure you don't use up your 100$ until you are done all your work in the course. The skills of managing cloud costs are very valuable.** Both in the Learner Lab and the real AWS figuring out what the money was spent on is surprisingly difficult after it's already spent. So pay attention whenever you see a note about the cost of anythingwiki.** You cannot use AWS Budgets in your AWS Learning Lablittlesvr.** You could try to figure out how to use the Amazon CloudWatch billing alarms* Always keep cost in the back of your mind when doing ca/anythingwiki/ on AWS = Basic security on a public-facing server = * A good AWS password, not used anywhere else* Remove default usernames* Whenever possible: don't use passwords at all, use SSH keys for logging in* root is never allowed to log in remotely* How to use sudo and how to configure it* ssh keys, same as OPS245* How to organise your SSH keys and not lose them = AWS networking = * Default dynamic public IP* Default static private network/IP* Reserving a static public IP under "Elastic IPs", cost of doing that = First AWS VM = * Deploy a pre-built Debian 10 VM ("Instance")** Instance type t2OPS345_Lab_1 This page has moved.micro - sort of kind of almost free** Existing security group "default"** Create a new RSA key pair named ops345-default-key, save it as ops345-default-key.pem on your workstation under a new directory ~/keys/ssh/* Differences between Debian and CentOS* Explore the VM:** connect with user ec2-user, ssh key** no yum, use zypper** systemctl** passwd, shadow, group files** netstat -atnup** Create senecaid-admin user, no password, add to wheel group, modify /etc/sudoers** Confirm can log in as senecaid-user and successfully sudo su** Delete ec2-user]
