Consul is a totally different thing to Cassandra. Consul could be built on top of Cassandra, but it would not provide any advantages. Why would you want to maintain a separate datastore?

Consul is a single static binary that uses around 11MB of RAM. Cassandra is a complex distributed datastore that requires the JVM and uses many gigabytes of RAM.

Why would you want to maintain a separate service discovery cluster?

Cassandra is not a service discovery cluster...

I think you're missing the point here. I don't know what else can be explained better.

You're missing the obvious here: they have no idea what they're doing. Which is pretty evident from every aggrandizing post on their blog.

How do you know the business team didn't ask the tech team:

"Should we rotate all the keys?"

And someone said: "Nope, we wrote this awesome custom allocator in 2001, all good!".

FWIW, we're still waiting for our cert to be reissued by Akamai. It's only been 6 days since everyone else reissued their certs. Great job team!

Our rep said the same thing even when we insisted they rotate our certs on day 1.

Of course we're still waiting. I don't know who's decision it was to not reissue all certs on day 1, but this is an epically bad decision bordering on gross negligence.

Heads should roll.
