The Guardian tells a story of their migration into AWS Aurora Serverless.

This article doesn’t go too deep into technical aspects, but provides a nice overview of the issues one may encounter when trying to move to Aurora.

A couple of things that I found interesting:

- Whatever cloud migration tools are there, pg_dump and pg_restore are your trusted friends.

- This paragraph:


We’re spending roughly $220/month for storage and compute for the database. For the same price we could have rented a db.m7g.xlarge (16GB RAM, 4 vCPUs) Postgres instance along with 100GB of EBS storage or a db.r7g.large (16GB RAM, 2 vCPUs) Aurora instance. I suspect both of these options would have done the job for us, and maybe not have suffered from the same cold start problems as our serverless database, but after 3 migrations, it’s probably time to get back to doing some feature work!

​​With your help we managed to deliver 18 medical kits to the 27th Separate Bataillon!

We had a new request from them for the winter boots and a thermal vision. We had some money left from the previous fundraiser, so the winter boots are on their way to the frontlines already. Now, we are raising funds for the thermal vision!

The goal is 85k UAH (~2200 EUR). This is the price for the thermal vision, but we still have money left. So, we will “break” the Monobank jar as soon as we have the required amount from all the sources.

Also, we work together with the UA Responders foundation to be clear on all the legal stuff. So, you can also donate to their PayPal or SWIFT, since Monobank sometimes has issues accepting money from the EU cards. Please, put “27” in the message if you donate via PayPal or SWIFT, so we know that these money are meant for the 27th Battalion.

Let’s continue with Serverless. I Reviewed 1,000s of Opinions on Serverless is a collection of takes on Serverless. The author has collected and analyzed opinions on Serverless from Twitter (RIP), Reddit, Hackernews, ans other websites and broke them down into 3 categories: negative, positive, and neutral.

Tl;dr: as always, it depends. Serverless is no silver bullet. You have to architect your applications from ground up and choose tools fit for purpose - not jump on hype trains.

In any case though, there are some good comments about Lambdas and stuff in this article.

I haven’t read it yet, tho.

For a bit longer than a week you can buy the Python Crash Course book from Humble Bundle with 45% discount.

I personally don’t use Python, but I know that it’s pretty popular in platform engineering. So, this offer may be interesting to you.

A comparison between EKS and AKS.

Tors article provides some insights into what to expect from each managed service. It’s a pity, GKE is not included into this comparison, I’ve heard a lot of good things about GKE. I believe, this is because this article originated from a specific use-case.

Programming Book Bundle by Packt.

I don’t know if you do programming day-to-day. Also, this channel is more OPS oriented, I would say.

However, you may find some interesting stuff there.

An interesting insight into Facebook's internal architecture. Basically, because of their size they could create a vast serverless platform for internal use that handles trillions of requests.

This article is a summary of a whitepaper published earlier. You can find this whitepaper in PDF format here. I haven't read it yet, though.

There’s a new test functionality in Terraform v1.6.0.

You can read more about writing tests for your Terraform projects in this article, which also has examples of the tests.

For someone who values tests for IaC, I’m very glad that such functionality is a part of the core. Although, I haven’t been working much with Terraform lately, implementing tests for Helm charts yielded some great results. I hope to write an article in that one day.

P.S. This article was kindly sent right into my inbox by Terraform Weekly. Do not hesitate to subscribe, you’d like to get the latest news on the most popular IaC tool.

DOU, KOLO та «Шалені Кабани» збирають 5 млн грн на 4 Mini Sharks для «Альфи» СБУ 🦈🔥

БО «Шалені кабани» — ініціатива, яку добре знайома DevOps-спільноті. На літній офлайн-події для девопсів в Києві ми зібрали гроші на мотор для човнів морської піхоти, а пізніше — ще.

До речі, новини про висадку українських морпіхів на лівому березі Херсонщини мають безпосередній стосунок до човників, над якими працюють «Кабани».

Тож, коли ми готували спільний збір, не мали жодного сумніву, що девопси активно підтримають колег та задонатять на 4 Mini Shark для ЦСО «А» СБУ («Альфа»). Адже потрібно зібрати 5 000 000 грн!

AWS Karpenter is in beta now.

Karpenter is AWS’ tool to manage and autoscale node pools in Kubernetes, which has more features compared to the Cluster Autoscaler and has deeper integration with AWS features. Yet, support for other major clouds is somewhere in the roadmap, IIRC.

This article in particular, describes what are the changes in Karpenter Beta compared to the previous versions and also guides you through depreciations and upgrade notes.

If you want to learn SQL, or you know somebody who wants (or should, lol), or you want to refresh your SQL skills, you can use interactive lessons on SQL Bolt.

They're simple, but good enough to get up to speed with the basics.
