Accidentally deleted my private subnet route tables in the process though, which broke S3 access for ~20 minutes. Could've been much worse #fail #outage

Shaved another $35 (40%) off my #AWS bill by disabling the NAT on my app subnets. Yay immutable infrastructure and VPC endpoints #win

I made a thing! https://www.burnfastburnbright.com/ Bootstrap 4, route53 domains, and terraform made this really easy. went from 0 to 100 in about 1.5 hours. #win

New in v0.117.0: nuked time-elements webcomponents due to Firefox breakage (cut js payload by a factor of 4), infra improvements to resume handling #win

The v0.116.0 deploy was done using a spot instance with packer. A bigger instance for half the price #aws

New features in v0.116.0: bootstrap4, removed RSS and Atom feeds, 100% webpack frontend build, css purification improvements, and healthz middleware

LOL that was only six years ago ... don't let your dreams stay dreams: https://hyperbo.la/lifestream/51/ #aws

welp that didn't last long. CloudFlare only queries a subset of NS records to check for liveness and has determined that I no longer use CloudFlare. Working on purging them from #terraform and registrar now #fail

It is a good thing that I've automated things well enough that I don't need the bastion #win

Even more cost savings: dynamically provisioned bastion cloudformation stack #terraform #aws

More cost savings. RAM footprint of a hyperbola backend is 143MB. Switch from t2.micro to t2.nano #aws #win

I accidentally created a CNAME (instead of an A record) for an IP today. Lots of confusing errors from nslookup, ssh, and host. Meanwhile dig appeared to resolve the record. #fail

hyperbola: now with multi-homed DNS. AWS Route 53 and CloudFlare, made possible by terraform. (In the process upgraded hyperbo.la mail to a 2048-bit DKIM key) #win #redundancy #devops

I accomplished this migration with ~no downtime #win. I spun up the new infrastructure and then deployed new AMIs with updated service records. I did have ~2 minutes of 500s when I accidentally overwrote old mysql DNS record due to a bad copypasta #fail

Switch from 3 to 2 backend machines. 1 is enough to handle the load I get, so use the bare minimum for redundancy #aws

Removed dependency on redis by switching to a django-provided database-as-cache adapter. My redis cluster was used only for admin sessions and caching a sidebar on the lifestream page. Unnecessary overhead #aws

Switched DB instance type from db.t2.small to db.t2.micro. From running my linode I know that MySQL never used more than ~400MB of RAM so I knew this was safe. My database is tiny #aws

Switched from Aurora to a multi-az RDS instance. I don't need the complex topologies that aurora allows and it forced me to use an overprovisioned instance type #aws

Now that I've shown I can go all out with the most expensive #AWS components, today I exercised my cost efficiency and right sizing muscles. I cut my AWS bill in half with the following steps:

3 AZs I feel so alive #aws

Just bumped backend ASG from 1 -> 3 t2.micros. With this change now all parts of hyperbola (redis, mysql, backend, lb) are multi-AZ #win

mysql_tzinfo_to_sql /usr/share/zoneinfo | mysql -u root mysql was the magic incantation required to get lifestream archive views working locally

The magic command to make homebrew work after uninstalling Xcode: sudo xcode-select -switch /Library/Developer/CommandLineTools #win
