Тимлид и subnet-полукровка: как одна строчка в YAML стоила $50 000 и двенадцати часов прода
Однажды, морозным ноябрьским утром 2024 года, я, как новоиспечённый тимлид не такой уж и маленькой команды, поверил в себя и в то, что спустя полгода изучения проекта и передачи дел от предшественника я полностью понимаю, как там всё устроено. Судьба обычно наказывает за самоуверенность. Не стал исключением и мой случай. Для понимания контекста добавлю, что я НЕ девопс - мне пришлось этим заниматься, и всё пишу через призму своего понимания проблемы. Возможно, сейчас придёт корифей AWS/CDK и скажет, что всё можно было сделать проще. Другими словами, не является индивидуальной инвестиционной рекомендацией. Смотреть страху в лицо

Today's Challenge: try to pull apart a #Cloudformation template (because #CFT sucks as an #IaC solution) and build #Terraform from it. Ive been working on this one all day. I mean, I even built #terragrunt hcls around it to deploy it DRY.
But does anyone deal with Cloudformation in AWS accounts and actually have a good opinion about it?
Because I can find NOTHING good about it.

Cloudy Mornings and Clear Evenings
In the past few decades, our knowledge of exoplanets has exploded, but we’re still relatively limited in what we can learn about these worlds. That’s due, in large part, to the indirect way we observe them. Most exoplanets are found when we see them transit, passing between Earth and their star. During a transit, the planet blocks a portion of the light we would otherwise detect from the star, letting us know that something’s there. We’re often able to measure the spectra of light passing through the exoplanet’s atmosphere, giving us a glimpse of chemical signatures.
Today’s study looks at exoplanet WASP-94A b, a gas giant tidally-locked so that only one side ever faces its star. In its transit, researchers could clearly measure different spectra from the morning and evening sides of the planet. The asymmetry seems to indicate that the exoplanet develops thick clouds on the nightside, which then dissipate during the daytime. (Image credit: H. Robbins/JHU; research credit: S. Mukherjee et al.; via Nature)

“Weitwinklig verzerrt” / Wide-angle distortion
A surreal scene at the Brooklyn waterfront a few weeks ago. Some weather phenomenon caused a straight-edged mass of clouds to vault over Manhattan and frame it in a perfect arc of clear blue sky, stretching horizon to horizon. The only way I could capture it was with a slightly distorted panorama shot (tap image for full view).

Hot take: No RDS instance should ever be part of a #cloudformation stack.
The technology is so immature that it is just a matter of time before the stack gets in an unrecoverable state.
Everyone knows this, this is why they suggest splitting stacks into persistent and ephemeral, but really listen to yourself. If it is too dangerous to put RDS into a stack that could need to be dropped, it shouldn't be in *any* stack.

[Перевод] Развёртывание .NET Aspire в AWS
Aspire отлично закрывает локальный цикл разработки, но как только дело доходит до AWS, начинается вечная развилка: «или пишем отдельный IaC и живём с двойной правдой», или «деплоим руками и платим временем и деньгами». В этой статье показан рабочий компромисс: один Aspire Host, который в локальном режиме поднимает LocalStack и контейнеры, а в publish-режиме передаёт управление AWS CDK и разворачивает полноценный serverless-стек (VPC, Aurora, DynamoDB, Lambda, API Gateway) — оставаясь в C# и без зоопарка YAML-файлов.

I've been working on a ton of #AWS #CloudFormation #YAML templates, a #GitLab CI/CD pipeline, and turning up quite a few things at work. My team was surprised at how fast I was able to create and deploy an application where its spec existed in #Microsoft Word and LucidChart documents, with the help of #Claude #Code #AI via #AWS #Bedrock. The elasticity and everything being on-demand (at my employers expense) is a very hard thing to turn down, where I can effectively do anything in the cloud environments, and not suffer with the on-prem environments that I cannot control due to work politics.
As I've been putting on the SRE hat lately, I've read plenty of documentation, implementation examples, run cost analysis, and more, for running apps on AWS. I've also learned that many developers do not understand the mechanics of a system, and how their application truly works, to get the best performance out of it. Sure deploying lambda's are a nice way to get something out there and not worry about it, but that ends up costing more depending on the usage than running a container on ECS / Fargate, which can handle plenty of concurrency.
It is much faster to deploy and make something with AWS CloudFormation, than doing anything with #Kubernetes, and even standing up virtual machines, #SSL cert, #DNS, all on-prem.

Over the past couple of months, my equipment at Hurricane Electric FMT2 has barely been touched. The closest idea I have for it now is putting a highly specced #Mac Mini there, run Parsec on it, and move to thin client type systems for both #mobile and #desktop, to have a centralized #workstation. -

[Перевод] Настройка .NET Aspire с AWS и LocalStack
Разработка сервисов с интеграцией в AWS быстро упирается в компромиссы: либо работать с реальным облаком и платить за каждый эксперимент, либо замокать инфраструктуру и надеяться, что в продакшене всё «взлетит». В статье показано, как с помощью .NET Aspire и LocalStack выстроить полноценное локальное AWS-окружение — с S3, CDK и реальной оркестрацией — так, чтобы один и тот же код без условностей работал и локально, и в проде.

Dusty Clouds Make More Ice
Even when colder than its freezing point, water droplets have trouble freezing–unless there’s an impurity like dust that they can cling to. It’s been long understood in the lab that adding dust allows water to freeze at warmer temperatures, but proving that at atmospheric scales has been harder. But a new analysis of decades’ worth of satellite imagery has done just that. The team showed that a tenfold increase in dust doubled the likelihood of cloud tops freezing.
Since ice-topped clouds reflect sunlight and trap heat differently than water-topped ones, this connection between dust and icy clouds has important climate implications. (Image and research credit: D. Villanueva et al.; via Eos)

“Vorticity 6”
It’s time for another storm-chasing timelapse from photographer Mike Olbinski! “Vorticity 6” focuses on supercell thunderstorms and their tornadoes. There’s billowing turbulent convection, undulating asperitas, bulging mammatus, microbursts, and more. There’s nothing like timelapse to highlight the growth, rotation, and shear involved in these storms. (Video and image credit: M. Olbinski)

Seeding Clouds With Wildfire
Raging wildfires send plumes of smoke up into the atmosphere; that smoke is made up of tiny particles that can serve as seeds — nucleation sites — where water vapor can freeze and form clouds. To understand wildfire’s effect on cloud growth, researchers sampled air from the troposphere (the atmosphere’s lowest layer) both in and around wildfire smoke.
The team found that smoke increased the number of nucleating particles up to 100 times higher than the background air, but the exact make-up of the smoke varied significantly by fire. Smoke particles were mostly organic, though inorganic ones appeared as well. The temperature of a fire, as well as what materials it was burning, made a big difference; the fire where they measured the highest particle concentrations included lots of unburned plant material, thought to be carried aloft by turbulence around the fire.

I built my website using @enhance_dev a couple years ago but I feel like I should use a more popular #IaC framework for deploying to #AWS like #CDK, #SAM, #Terraform or just raw #CloudFormation.
The problem is, I'm spoiled; Enhance makes #serverless so easy. I find myself just reimplementing all it's features; file based routing, html templates, session management, etc.

Penguin Poo Seeds Antarctic Clouds
Forming clouds requires more than just water vapor; every droplet in a cloud forms around a tiny aerosol particle that serves as a seed that vapor can condense onto. Without these aerosols, there are no clouds. In most regions of the world, aerosols are plentiful — produced by vegetation, dust, sea salt, and other sources. But in the Antarctic, aerosol sources are few. But a new study shows that penguins help create aerosols with their feces.
Penguin feces is ammonia-rich, and that ammonia, when combined with sulfur compounds from marine phytoplankton, triggers chemistry that releases new aerosol particles. The researchers measured ammonia carried on the wind from nearby penguin colonies and found that the birds are a large ammonia source, producing 100 to 1000 times the region’s baseline ammonia levels. In combination with another ingredient in penguin guano, the researchers found the penguins boosted aerosol production 10,000-fold. That means penguins can actually influence their environment, helping to create clouds that keep Antarctica cooler. (Image credit: H. Neufeld; research credit: M. Boyer et al.; via Eos)

“Monsoon 7”
Storm-chasing photographer Mike Olbinski (previously) returns with another stunning timelapse of summer thunderstorms in the western U.S. I never tire of watching the turbulent convection, microbursts, billowing haboobs, and undulating clouds Olbinski captures. His work is always a reminder of the incredible power and energy contained in our atmosphere and unleashed in cycles of warming and cooling, evaporation and condensation. (Video and image credit: M.
