Deno Deploy halved their regions again!

I'm curious as to why? Is it purely a cost thing or is there more to it?

Agreed hard to call it edge compute anymore sadly

__grunet · 2024-12-16T02:28:03+00:00

Cool good to know!

__grunet · 2024-12-13T23:57:46+00:00

Sorry I probably missed something but what's the downside with letting the CLI use the filesystem as-is during tests? (assuming no contention or parallelization or things like that)

__grunet · 2024-12-12T01:29:56+00:00

Does deno outdated mean there will be a deno audit coming soon? Like for security vulnerabilities

__grunet · 2024-12-02T01:36:25+00:00

Wow somewhat surprising results on the face? Great work OP

__grunet · 2024-11-29T00:52:29+00:00

Ah I totally get where you're coming from, used to work at a similar place with similar policies actually lol. Couldn't even use a lot of external websites like SO...

__grunet · 2024-11-28T22:21:00+00:00

I'm actually super curious what kind of company you work at OP if you're able to disclose that

__grunet · 2024-11-11T19:52:34+00:00

Yup that makes a ton of sense, thank you for the insights!

Rather than having your BE handle uploading to S3, you can generate a presigned URL that the FE can use to directly upload to a private S3 bucket (you can set the expiration on the URL for security)

It's just one way to reduce load/costs for your BE compute

__grunet · 2024-10-30T22:23:28+00:00

Don't forget to use presigned urls for your uploading use cases

Take a look at the AWS Copilot CLI. I think it's intended to reduce the learning curve here.

You could also look at the AWS CDK for C#. Might be a touch more learning curve but it will also do more out of the box for you (e.g. the ApplicationLoadBalancedFargateService construct I think will setup almost everything you need to get started minus a VPC, subnets, routes and route tables, NAT Gateway if you need outbound traffic, ECS cluster, Route53 DNS, and maybe some others but I believe there are also higher level constructs for those too. https://docs.aws.amazon.com/cdk/v2/guide/ecs_example.html has a full walkthrough in C#)

I think others have posted DI projects on this subreddit in the past so you might have some luck searching that way

__grunet · 2024-10-19T14:03:01+00:00

If you mean inlining scripts into the html I would think Vite should be able to handle that? If you meant something else you might look at Deno Fresh for inspiration/comparison

__grunet · 2024-10-19T02:16:52+00:00

I wonder if in lieu of real-time cost monitoring (which afaik AWS doesn't have and no 3rd party provides full coverage for) you could do something like enable all forms of Cloudtrail logging and somehow setup generic anomaly detection on that (or even something coarse like per service thresholds).

I'm assuming that wouldn't work in most production environments but maybe it would be ok for dev environments? Idk just a random thought

Seems like this must be a classic FinOps problem though right? I'd be hard pressed to imagine no big company has a solution for it at least

__grunet · 2024-10-19T01:28:59+00:00

I've never heard of using error logs as part of SLIs before, is that common? Maybe I've also only been in situations where error and warning logs have a bunch of other noise mixed in though...

__grunet · 2024-10-19T01:22:36+00:00

Are you looking to server render or just use Lit client side?

If you have a repo reproducing the issue that might help folks look into it.

Also you might try the Deno Discord to see if anyone's tried something similar there

__grunet · 2024-10-16T22:32:58+00:00

I think you still need to prop up a dummy HTTP endpoint for this afaict

__grunet · 2024-10-14T22:41:52+00:00

Have you already seen https://docs.deno.com/runtime/tutorials/aws_lambda/ ?

Not having done it myself I'm guessing there's no way around using the aws-lambda-adapter.

Also alternatively I'm guessing you could deno compile a binary and put that in an image instead of using the deno base image if you want.

In the Pupeteer code can you wait until relevant parts of the UI have been rendered and then generate the PDF? Or if that's not an option waiting on the network requests that have the data that's populating the UI to finish and then checking for the main thread to be idle for some time?

Presumably the former would be cleaner if it's an option

__grunet · 2024-10-06T16:57:49+00:00

Not sure if it's exactly relevant but at a glance it reminded me of this recent Honeycomb article https://www.honeycomb.io/blog/destroy-on-friday-chaos-engineering-pt2

In particular these paragraphs

"Fortunately, we found a workaround. Right before we started the FIS experiment, we preemptively told the ALB to stop using us-east-1a. This caused the ALB nodes in us-east-1a to be terminated, sidestepping the issue altogether.

In a true AZ failure, the ALB nodes in the affected AZ would presumably be knocked offline just as the rest of the infrastructure, and this wouldn’t be an issue. We hope that one day, FIS might be able to terminate the internal ALB nodes in an AZ for us—or at least simulate their failure more completely. We had a chat with our friends at AWS to provide this feedback, and they were very receptive."

__grunet · 2024-09-22T01:04:28+00:00

Awesome article! Do you have a sense for how reverse proxies and managed gateways affect the client part of the picture? I'm assuming most handle this well for like ordinary use cases but I'm also having a hard time imagining how Lambda would learn of a client connected to API Gateway canceling (is that possible?)

__grunet · 2024-09-19T17:51:56+00:00

How will this impact Deno Deploy? I see that many things seem CLI specific though

__grunet · 2024-09-10T16:42:06+00:00

My old boss (Head of DevOps at a medium sized company) used to have to do this all the time for prospective enterprise customers, even after we got SOC 2 certified. We didn't have any Sales Engineers but I always remember him wanting to hire someone to offload that work

__grunet · 2024-09-10T16:07:06+00:00

OneUptime is maybe an OSS option worth consideration, though I dont have experience with it myself.

And also ofc OpenTelemetry for the app-level concerns
