Have to agree with the others. For example, while setting up ELB it's possible to select at least one option (un-checking the Public IP box) that causes the setup to just fail with a nonsensical error message. Turns out ELB requires a public IP to communicate with the nodes. That's just the most glaring one off the top of my head.
I also remember trying to set up SFTP whenever it was first released. It was literally impossible to do what they were advertising (S3-backed SFTP with jailed homes for each user) without writing a manual json config (I never got it to work). I had built my own solution for this exact thing on EC2, using a bash script more or less, and thought the hosted option would be less of a maintenance burden. Needless to say I quickly gave up.
The more annoying part is that the service only supports public/private key logins. If you want user/pass you have to write a lambda. The lambda is pretty simple though, it checks the credentials (so it can hit any backend you like), and if they pass it returns a 200 with a json doc of role (which is just sftp assume role), policy (the scope down from above), and home dir.
This touches on a larger issue with AWS though. It's that they are trending to leave out functionality and point to lambda as the solution. On one hand, I get it. The lambda solution is infinitely more flexible, but what if I just wanted an sftp for a couple users that uses user/pass?
To your final point, it is so much less maintenance. There is no server to manage, and since I want all the data in s3 anyway, it's already there. This solution replaced a server with chroots, EBS, scripts to move data to s3, etc...
terraform 'destroy' isn't infallible. There are certain resources that trigger the creation of other resources (for example, lambda functions will create cloudwatch log groups, and dynamodb tables create cloudwatch alarms) and when terraform destroys the resource, it doesn't necessarily clean up all the associated resources.
Terraform has it's shortcomings for sure, but I don't think it's reasonable to expect Terraform to go out and clean up second-order effects of it's resources.
I'm not doubting that the situations you describe are true, but abandoning resources like that is an AWS-lifecycle problem, not really a Terraform one.
Sure. My point is just that `terraform destroy` doesn't necessarily solve the problem at hand. And you could still end up continue paying for those second-order effects after running a terraform destroy.
I am pretty senior and can thus sometimes afford to do a new thing and try doing it the right way, at the same time. Not even always. Many people just take one learning curve at a time...
Typically Terraform takes longer to get something working than mindlessly clicking through the console. In my experience those mindless clickthrough things end up sticking around for years even when they weren't intended to.
This is why you have separate development and production accounts: a development account where you mindlessly click through so that you can learn through the UI what's available and how it works; cleaned up on a regular basis by something like aws-nuke, and a production account where you have the discipline to only create resources through Terraform / CloudFormation etc.
Even CDK sucks though because if you’re still kinda new to it all, you want to login and make sure that it’s all hooked together correctly. And you’re back using their shitty UI.
Why you can’t look at the load balancer, look at the listener and then show what’s in the target groups is beyond me.
I have a different take on it. I started out doing everything through the console, then learned the cli and boto3, and very recently CDK.
CDK is another tool that build on the cli and boto3 concepts, and also manages the orchestration and dependencies.
Having to go back to the console isn't a fault of CDK. Learning the right tool to use for a situation is part of the learning curve. I go back to the console all the time to look something up quick or to understand what config options are available. Or I repeat the same steps in the console enough times that I get bored with it and automate
Edit: also I tried and have given up on CloudFormation more than once. CDK is like a wrapper layer around it, and has been pleasant to use.
