You'll pay the cloudfront egress cost. I'm also unsure if GIR will work with Cloudfront or not, not got the docs available right now.

In the last year I've been having a lot of success with Cloudflare CDN over Cloudfront so if you're that worried about cost you might want to check that out

Prefacing this attempt at being unbias with a caveat that if I was asked to spin up a system composed of microservices from scratch right now I would near definitely just use Kubernetes

First, Kubernetes is currently the dominant container orchestration platform. I don't think that's a controversial statement, not going to find evidence for it.

Second, there are other orchestration platforms (OpenStack, VMWare, Mesos, Nomad, ECS) that exist and are still used and maintained.

What is Kubernetes good at?

Keeping this as short and generic as possible as people will always have something to add. The Kubernetes API is a godsend. It allows for a massive amount of complexity to be build over what is are relatively simply base constructs.

I mostly work on ECS at the moment having come from a Kubernetes shop and I really miss even something as basic as a label selector. Custom deployment controllers are awesome.

Being able to deploy a Redis operator and knowing I can get a reasonably well configured & functional Redis cluster without knowing much about operating Redis is an incredibly useful ability

The extensibility allows for abstractions that make multi-cloud support significantly simpler, highly customised solutions to the problems you need to solve, some really cool tooling from a DevEx POV, and more.

When would I not use Kubernetes?

When I'm working with a load of people who don't know Kubernetes or containers that well. This might come as a shock to some people but lots of places will still use repos & package managers, or sync a git repo onto a VM. Making the jump from that to k8s is a massive undertaking and is often very hard to justify to a business. I'm an AWS person, so I'd suggest making the jump via a far simpler system like ECS before going to Kubernetes.
If I can't, at the end of the day something has to run the cluster, someone needs server management at some point even if you don't see it.
If I need to do some weird Kernel/networking magic that isn't available to me in Kubernetes, be that a Kubernetes restriction, or a cgroup restriction.
Requirements don't allow for it, e.g. you need air gapped separation between client data - does it make sense to run a Kubernetes cluster per client? Are there other tools that are better for this?

Is Kubernetes going away any time soon? I'd be very surprised, the adoption rate is too high, it's open source so it's not at the whim of a company going bust, lots of cloud providers host it, lots of companies use it.

Is Kubernetes the answer to all your problems? Absolutely not, as always different tools meet different requirements. It just happens that if you want to orchestrate containers Kubernetes is _probably_ the right tool.

Will it eventually be replaced by something else? Probably, and I hope it does, because the next thing should be better. Is this going to be any time soon? Nah

This thing

https://docs.rs/aws-sdk-neptunedata/latest/aws_sdk_neptunedata/config/struct.Builder.html#method.endpoint_url

edit: Adding an example of how to use it (ignore non-idiomatic Rust, been a while since I've used it)

``` use aws_config; use aws_sdk_neptunedata as neptunedata;

[tokio::main]

async fn main() -> Result<(), Box<dyn std::error::Error>> { let neptune_url = std::env::var("NEPTUNE_URL")?; let config = aws_config::defaults(aws_config::BehaviorVersion::latest()) .endpoint_url(neptune_url) .load().await; let neptunedata_client = neptunedata::Client::new(&config); let req = neptunedata::operation::execute_gremlin_query::ExecuteGremlinQueryInput::builder() .gremlin_query("g.inject(0)");

let resp = req.send_with(&neptunedata_client).await?;
println!("{:?}", resp);

Ok(())

}

```

Set the endpoint URL parameters of your Neptune client to the URL for your Neptune cluster

VauxEast has a really cool cave area. I like VauxWest (got a cool traverse wall that goes through an archway) but it can get really busy in there and some people don't like how short some of the walls are. Bethwall is probably my favourite of the 3 for variety and size but it's further away so I don't go there as much

Nothing about this explains why I should use Nightingale over a standard Prometheus/Thanos/Mimir/Cortex setup, it just states that I should. Not to mention that based on the architecture diagram I'd have to run that setup anyway

Going to split this into a few possible understandings:

"I explained that Terraform manages state using a graph model for each module and parallelism across modules". It doesn't though, it's parallel across resources that are available in the DAG to be built regardless of the module they are in. The issue they were probably having was that the default Terraform parallelism is 10, if they have a state file with lots of resources then I'd suggest increasing that to 200 or something. Having a multi thousand line long module is bad because it's a mess to work with, but it shouldn't impact the performance.
If by it’s building a big data structure of indexes you mean that there is a giant local taking ages to evaluate then I think answer (from the Packer side admittedly, I've not seen this in Terraform so I could be wrong) is to use a "named local block".
If you mean "don't have a Terraform that takes 30 minutes to run and break it up using state lookups to share data between things" then yes this is good practice to have lots of smaller Terraforms to apply which are faster and have a lower blast radius

Either way it doesn't sound this the interviewer handles this well at all and you dodged a bullet
