You have no idea what you're talking about. It is clear you have not had to perform any incident response or forensics.

Accept the fact that remote logging is necessary (and cheap) for both security and stability reasons.

This was a nice ad hominem attack but I'll respond anyway. I actually have multiple certifications in computer forensics, and have done forensics and incident response for eBay, PayPal, reddit and Netflix.

I'm an open minded person and I'm willing to change my opinion in the face of new facts, but you haven't actually presented any new facts. Do you have any use cases that support your statement?

I have a few facts that counter them. Central logging is definitely not cheap. It costs a lot of money to store those logs at rest, and more money to store them in a way that is searchable, as those data structures expand pretty quickly. It also isn't necessary to stability, given that we made stability go up after we ditched central logging at Netflix (I will be the first to admin this is correlative and not causative, but still, it isn't necessary for stability).

When security at Netflix needs to investigate for incidents, or to analyze data for anomalies, how do they go about doing it? If I recall correctly, Netflix is an Elasticsearch / Kibana shop right? Are there multiple clusters that they gather info from? How is visibility done for the overall org?

I'm genuinely curious how the security team goes procedures of analysis there.

I'm not sure how much detail I can get into, but yes, there is a large Elasticsearch cluster with a lot of application data as well as web application firewalls and IDS data.

In all my years of lurking on HN, telling jedberg that he has no idea about large scale networking and security procedures is probably the funniest thing I've ever read...

Hint: google his username.
