I hate Clouds - a personal perspective on why I think Clouds suck
I hate Clouds - a personal perspective on why I think Clouds suck
I hope this won't be counted as some form of self-promotion, even though I am sharing a post from my own blog.
As a tech worker who works in a Cloud shop, I wanted to elaborate the many reasons why I find working with Clouds terrible, from multiple points of view.
I tried to organize my thoughts in a (relatively long) post, in which both technical aspects and political aspects (which are very related) are covered.
I am sure many people will have different perspectives, and this could be potentially also a nice prompt for a discussion.
You're viewing a single thread.
Very good read. I totally agree with your sentiment that more and more, "engineering" is becoming just gluing together and managing cloud services and features.
My job as a sys admin has become the same. It's not about actually understanding the technology at a deep level and troubleshooting problems, it's about learning specific applets and features to click on and running down daily and weekly checklists.
And that's a good thing, IMHO. As an architect I don't want to rely on some single genius knowing secret incantations or anything like that.
Boring, tried and true services, repeatedly put together and if the organization allows the time for it, with excessive documentation.
Is that what you get with Cloud? Because there are still a million ways to shoot yourself in the foot. The main difference is that the single genius doesn't need to implement things him/herself, but decisions still need to be taken and fragile setups can still be built.
Imagine an ec2 instance in a satellite account performing some business critical function with an instance role, whose custom IAM policy allows to do it in another account. Clouds are not giving you good engineering, they are giving you premade building blocks, you can absolutely still make a mess with those. Even more, the complexity and the immense portfolio of features can allow very creative ways to build very low-quality systems.
I think you can have good, boring, simple systems built by engineers. With or without Cloud services.
You can still make a mess, but you can't fuck up the building blocks, so it's a big improvement.
Using an ec2 instance is already a yellow flag, you have higher level services for most tasks.
Yeah in general you can't mess the building blocks from the PoV of availability or internal design. That is true, since you are outsourcing it. You can still mess them up from other points of view (think about how many companies got breached due to misconfigured S3 buckets).
No one's talking about secret incantations.
They're talking about knowing how your applications actually work, so you're not tied to the whims of a third party.
Hence or anything like that.
If people don't know what your systems actually do, you're going to have huge problems at some point.
Where did I request for "not knowing what systems do"?
That's literally the entire chain you clicked down.
The fact that cloud provider calls aren't based in any kind of core principles and force you to spend all your resources understanding their nonsensical structure instead of what your code actually does.
Wrong. You don't know how it's implemented, but you very much know what they do. Even heard about abstraction?
Abstraction is great. When it's meaningful.
Cloud abstraction adds massive complexity that has no correlation to what your code does.
An di shouldn't. Separation of concerns.
