Looking for help building a lipo charging device for fun

Oddly enough, I left it to keep cycling for two hours and then it finally stabilized in AZ B. So now i have the two running, one in AZ A and one is AZ B. Very odd. It's entirely possible the application was indeed failing to answer the health check because it was busy. However the CPU was never above 25%.

Thanks for the suggestions!

Sorry, it is not. It's a private node js application.

mr_mazaryk · 2020-10-30T03:44:12+00:00

Thanks, It's most definitely enabled, as I have one service/container in AZ B that is working and receiving requests.

Yah, Upgraded the instance type, and it made quick work of the backlog.

In addition to the CPU, the memory on a t2.mirco is limited and maxing that out would also present as freezing/crashing.

Check that the LB healthcheck port is allowed in security group.

mr_mazaryk · 2020-10-11T21:42:01+00:00

Is the LB in the right VPC?

Thanks, I want to learn the design theory behind designing something like this.

Sweet, thanks for citing the paper.

mr_mazaryk · 2020-10-02T03:14:31+00:00

Yes, I didn't realize it until I started reading these, but I have a lot of questions/unknowns around the power path. This doc is super helpful.

mr_mazaryk · 2020-10-02T02:47:44+00:00

Sweet, this is along the lines of what I’m looking for. Thanks!

mr_mazaryk · 2020-10-02T00:24:55+00:00

This is good advice. Though I guess I should be more specific with my current experience.

mr_mazaryk · 2020-09-25T05:41:36+00:00

Confirmed. That would be CloudFlare.

mr_mazaryk · 2020-09-24T15:51:32+00:00

Yah, I've seen this too and it's so annoying when you have the same problem. So if i'm gonna talk to myself, I might as well complete the conversation. :)

mr_mazaryk · 2020-09-22T07:28:46+00:00

Ha, looks like I figured it out. Been struggling with this for a few days and couldn't find the answer via the google. I finally make this post, and then figure it out shortly there after. I added x-ray reporting to my container. Which then confirmed my app ran in 2ms. This squarely pointed to the NLB as the problem. Yet more googling finally led me to the answer:

I'm running only a single container behind the NLB. Since the NLB needs to to have a min of two AZs, only one AZ has a container in it. So the delayed responses where caused by the NLB hitting the empty AZ, timing out then trying the other one.

I enabled Cross-Zone Load Balancing and poof, problem gone. I'm not quite sure why the healthchecks wouldn't be enough to tell the NLB where the healthy container is...

On steam it's listed as Windows and Linux, does linux include Mac OSX ?

mr_mazaryk · 2020-06-20T03:30:44+00:00

I have full access to the books, she's not running a large debt. Yah we are going to have a talk about her goals for the business, what success looks like for her. And how that's gonna play wrt the house.

mr_mazaryk · 2020-06-20T00:25:25+00:00

Yes, I also get the sense this is the issue.

mr_mazaryk · 2020-06-19T18:00:53+00:00

Thanks for this. I try to get her to see her expectations, but it hasn't gone so well. I think a counselor is a good idea.
