The "environment" absolutely should _not_ be part of the name of the resource.
Coupling the notion of "environment" with your workload (be it in their name or their configuration files) is an anti-pattern that I wish people stopped following.
If you have 3 environments, dev staging and prod, you want resources in these environments to be named _exactly the same_ in each environment.
Whatever your workloads are, wherever they run, they themselves should never _be aware of the environment they run in_. From a workload's point of view the "environment" and its label (dev, staging or prod) do not matter. What makes a workload a "dev" or a "production" workload are their respective configuration and the way they differ, _not_ the name of the "environment" they run in.
What makes a workload a "dev" workload is dictated by its configuration (which database host it talks to for example).
When the environment is being coupled in the configuration of your workloads, inevitably a developer will end up writing code like:
if env == 'dev' then use_database("dev.example.com")
This won't work at all at scale as people start adding new environments (imagine, "qa","test", "dev_1", "alphonso's_test", "etc") as developer will start adding more and more conditions:
if env == 'dev' then use_database("dev.example.com")
if env == 'qa' then use_database("qa.example.com")
if env == 'dev_1' or env == 'alphonso' then use_database("dev_00.example.com")
// ... add more and more and more conditions
Instead, if your "dev" environment must talk to a "dev.example.com" database, create a variable called "DATABASE_HOST".
And for each environment, set the "DATABASE_HOST" to the value of the database this specific environment needs to talk to.
For example, for your "dev" environment DATABASE_HOST = "dev.example.com", and in your prod environment DATABASE_HOST = "prod.example.com". Here we clearly have a "dev" and a "prod", yet "dev" and "prod" are merely a "labels" for us humans to differentiate them, but the _configuration_ of these environments is really what defines them.
The code above then simply becomes:
use_database(DATABASE_HOST)
and _this_ ^ will scale with an infinite amount of environments.
_Configuration_ defines the "environment" _not_ the name of the environment.
edit: I realize the article is talking about your cloud provider resources and people might be running multiple "environment" resources in a single account. The above applies to "workloads" talking to these "cloud provider resources", not to the resources themselves, since, of course, you can't have 2 DBs named the same under one single account (obviously the names would collide).
- wutwutwutwut 5y ago> If you have 3 environments, dev staging and prod, you want resources in these environments to be named _exactly the same_ in each environment. So your production database server has the same resource name as your dev database server? Good luck running that on Azure. Re your edit: When people have strong views ("absolutely not") and rants about it and yet does not seem to grasp what the article about, I think the opinion of those people should be ignored. Consider that.
- gouggoug 5y agoEh. Sure, I slightly mis-read the article, it happens. Just preface my block of text with a "tangentially, when it comes to 'workloads' ... [the rest of the block of text]", and now you have a generic comment, not about the article, but about something related.
- wutwutwutwut 5y agoWhen people skim through something in a sloppy way and then focus on writing a rant about it I just don't take their view seriously. If people can't be bothered to carefully digest information, I just assume that they don't know what they are talking about. You may be right or wrong, but I would just choose to listen to people who did their homework instead.
- alexanderdmitri 5y agoSeeing as these are the only two comments you've made on this thread, it seems like you're not ignoring what you claim should be ignored and taking all this a bit too seriously. Whether it makes sense to add the stage name to a resource name is a decision that is informed by a wider context that includes hosting environment, deployment pattern and configuration approach. It can make sense in some situations and can be a bad idea in other situations.
- plasma 5y agoI think it is helpful to include environment name - they show up in UIs, consoles, DNS names, etc, and provide the operator a sanity check what environment a resource is in at a glance.
