🎤 After several months of procrastinating, I finally started working on "𝗧𝗵𝗲 𝗘𝗹𝗲𝗺𝗲𝗻𝘁𝘀 𝗼𝗳 𝗖𝗜/𝗖𝗗" course. 🎉 1. Visit elementsofcicd.com to learn more. 2. Register for the waitlist to receive early sneak peeks as I add content. All feedback is welcome 🙏

Maybe I could hack this around with the "promotions" feature that specifies a `pipeline_file` to continue execution. During the main pipeline execution, I could overwrite the specified `pipeline_file` content with the right one, which will be evaluated at promotion time?

Does support pipelines generated during the main pipeline execution? i.e. The workflow starts with "semaphore.yml", but then the next steps are generated in one of executed steps. In the docs, I can only see pipelines statically created and versioned in the repo...

I still hope... Maybe the new trend of Infra from Code will make a dent in the right direction. Or maybe it won't. Maybe I will just build the platform I want. Or maybe I won't. But, I am confident, that in the next decade I will find a platform I like 😅 6/6

Current "new" platforms, fall into two categories. 1. Insanely expensive (some even exceed Heroku) 2. Very restricted I want the AWS infra blocks, offered in nicely packaged solutions. We just need to pick the pieces and put the puzzle together. Stop reinventing shit. 5/...

Serverless offerings, with newer Infra as Code/Infra from Code tools, gets us closer to the dream. However, having always on servers running, with zero downtime deploys (even single instance), persistent storage, and nice DevX, is required for many apps. 4/...

How did we mess up running applications on hosts so badly. Tens of tools promoting Heroku-like experience, on Kubernetes. Why the hell do I care about K8s. The implementation detail. I should only specify CPU x RAM, or a max budget $$$, and the platform handles the rest. 3/...

K8s came, solved some issues, and in the process got abused by every single engineering team. We created more issues than we solved. Then, created hundreds of products to tame K8s itself. From DevX, to cost-optimization, to platforms that manage Managed K8s services 🤯 2/...

I have been going through tens of cloud platforms and still didn't find one I like. looks very close, but I don't like Python 😭 Do you have plans to support other languages? Ideally, Go, Kotlin? 🙃

More people are leaving Twitter due to the latest policy changes. You can follow me on other social media platforms: LinkedIn, Mastodon. I also have a newsletter, and RSS, for my website, which I will be updating more often now :) Links for everything on my website 👇

Nice thread on concerns I have as well. ChatGPT is a great improvement, but it's still nowhere ready for production use anywhere other than replacing TikTok time when we are bored...

I've been reading lots of these generated texts, and they are amusing, but is also scary how easily our human brains fall for the surface illusion and don't look deeper. twitter.com/biblioracle/st…

Really amazing article on how to think about your finances. Especially if you work in an industry like tech.

4 years on, this remains one of my favourite, most important blog posts (it’s also in my “Pwned” book with a lot more context). Should I do a follow up? Especially given how these lessons saw me through a difficult period of life, there’s more to share. troyhunt.com/10-personal-fi

AWS/Amazon Verified Permissions is really one of my favourite releases of re:Invent 2022. I have high hopes for this product, just from what I saw and read so far. Lots of custom authorization code to be thrown in the bin. Great overview: youtube.com/watch?v=k6pPcn #AWS #Security

I love how the AWS re:Invent 2022 videos were up just a few hours after being delivered in-person. Also like how they provide playlists scoped to domains, along with the bigger playlists to watch everything :) There are some super interesting talks to watch for days to come!

Without a shared file-system and a warm pool of EC2 instances, there is a big delay on the failover until the SQLite is fetched locally (S3 case), or until a new EC2 instance is started to mount the same EBS volume of the failed instance (EBS case).
Show this thread
The scenario I have is one SQLite file per customer/tenant. Then, a pool of EC2 instances that "handle" each tenant with affinity (sticky). Even if an instance fails, another one from a warm pool can pick that tenant up in a few seconds, and continue responding to requests.

Maybe with this performance boost, we can finally use SQLite databases directly from EFS with acceptable performance :) Needs some experimentation over the weekend, maybe!

The CodeCatalyst website seems to not be in-sync with the AWS Console... Then, I try to create a Project in CodeCatalyst with the "Scratch" blueprint, and I get an error that I am over the limit, while not having any project at all yet...

This is a very big game changer, if it works as advertised! Application level authorization using IAM style policies!

I had the same thoughts with this post, so many times! Providers, *cough* AWS, just put the #serverless label everywhere now. I wouldn't be surprised if there was an EC2 feature labelled as serverless at this point. "The Litmus test for Serverless" is what I always want too 👇🏻

Will the real #serverless please stand up? Serverless unlocks developers! #fakeserverless is diluting it into a marketing term. @NoSQLKnowHow and I present the @momentohq litmus test for serverless 👇 gomomento.co/3Oh4ZtN
