Yet another observability post: Datadog Alternative: When to Move Out? . This article describes a fairly simple experiment: what would it cost to run Datadog compared to Prometheus & Thanos on different scales. Although, the scope of the experiment was somewhat limited (no logs, no APM), it provides some numbers that you can use while evaluating different observability solutions. The bottom line is: with the growth of your technological footprint, Datadog price grows faster compared to the Prometheus stack. Which is true for any SaaS solution compared to self-hosted, I believe. However, another important considerations is that free software is not "free". You cannot just replace a vendor with an open-source tool and call it a day. You require engineering time to support and maintain those platforms. Therefore, on a smaller scale it might much more effective to use SaaS (especially, if you don't have experts in a given domain in your company yet). #observability -

Some good practices for Argo Workflows. I'm not super familiar with this tool, so I'd just list the points here: - Use common templates - Limit parallelism to control cluster resources - Avoid nested loops - Collect metrics from your workflows - Use lifecycle hooks - Control long-running workflows or break down long workflows into separate smaller ones - Integrate with Argo Events #argocd #cicd #kubernetes -

It may happen that you have a catch-all repository to store some work that may or may not be important. Notice, it's not quite a monorepo pattern, rather a single junkrepo. Like, I saw devops,utils,tools, and similar repositories in quite a few companies. But what if some things from those repos are actually important, and you want to have a dedicated home for those things? Here's a guide by GitHub that explains how to separate things from a repository while saving the Git history. This guide is created by GitHub, but it should work with any Git repository. Although, I only tested it with GitHub. Enjoy! #git #github -

I personally don’t know this publisher. Yet, the titles of some books look interesting. For example, there is a book about FinOps as well as “Kubernetes for Jobseekers” (lol). This is a Cloud OPS and Development bundle by BPB. If you know this publisher or have any feedback on these books, feel free to share your impressions in our chat (chat is in Ukrainian). As usual, you can pay different amount to unlock different number of books. This bundle is active for 20 more days. #books -

Today's Donations Monday request comes from our friends' channel - Ukrainian DevOps Digest. They are raising funds for a retransmitter for the 28th brigade. Here's the link to the Monobak jar: https://send.monobank.ua/jar/2cEiqdkjQ3 Pro-tip: if you copy the Monobank jar link into your mobile browser, you should be able to select Apple / Android Pay as a payment method and thus pay from a different card. It doesn't work all the time, but this is a nice workaround in case you don't have a Monobank or another Ukrainian card. #donations #Ukraine Українська девопсарня Привіт любі кошенята 😺😺😺! Мої друзі з 28 бригади ✝ ✝ ✝, які зараз під Бахмутом потребують одну дуже цікаву вундервафлю. Доречі, ви цих героїв також знаєте і вже їм допомагали, ось тут вони разом з тераканом на фото (теракан досі виконує бойові завдання)😃 Ретранслятор хоч і дорогий, але вкрай необхідний для успішного виконання штурмових дій . Бо зв’язок це координація, це вчасні рішення, це збереження життів наших воїнів і трошки навпаки для ворога 😏😏😏😼😼😼 Для цього збору ми вирішили об’єднатися з іншими волонтерами які перевірені і які зберуть половину. Тож з нас — друга половина. 💵 🏦 Посилання на банку: https://send.monobank.ua/jar/2cEiqdkjQ3 Наближаємо перемогу, любі! 🇺🇦🇺🇦🇺🇦 А щоб трішечки додати мотивації — після того як зберемо я обіцяю вам статтю про те як інтервьювити девелоперів так щоб зрозуміти що в них насправді болить

Wanna share a video with you about WTF is Platform Engineering. https://youtu.be/ghzsBm8vOms I would say it's good enough. Mostly because the reality is usually more complex than the theory. However, if you were wondering WTF is Platform Engineering, this is a good start! (and no, platform engineer is a specialization, not profession!) #platform_eng -

Another article from our subscribers. My experience migrating my infrastructure from Terraform to Pulumi is a story of the IaC migration to… well, Pulumi. A nice thing about this article is that it has some concrete examples of code as well as recommendations out of experience. Yet, the final thoughts are somewhat questionable. For example, the claim that Pulumi is faster without any measurements. BTW, I also wrote an article about Pulumi 3 years ago. It’s obviously outdated today but it’s interesting to observe how the project evolves. P.S. If you want to share an article or just have a casual conversation, do not hesitate to join our chat (chat is in Ukrainian). #pulumi #terraform #iac -

Handling concurrency is hard, even if it was made simple. The Go 1.19 Atomic Wrappers and why to use them explores the sync/atomic package which was introduced in Go 1.19 and use cases for it. I haven't used this one personally, but we have sync.Mapin one of the projects to get the results from goroutines in one place. #go #programming -
