Hello and welcome to my latest weekly progress report.

I’m a bit late to this week’s update, I normally do these on Fridays as a way for me to reflect on the previous week, but on Friday I was busy helping a new potentially large AutoSpotting customer get started.

Hello, and welcome to this week’s update.

Without further ado, let’s dive right in.

Little recap from last week

In my last week’s update I mentioned how I’ve been working most of the week helping a new customer onboard.

They were reluctant to run the latest AutoSpotting version because of their blue-green deployment strategy, but they wanted to try an older version that still works in the legacy cron mode. They were initially very happy about the way I supported them to use an older version, and even said it was the best support they ever got from a vendor.

LeanerCloud GUI work

I spent most of the week continuing the work I did last week, and here’s a little demo video that shows the progress I made and how the UI looks like so far:

I’d love to hear your feedback about it, and what kind of things you’d like to see in this tool besides what I mentioned in the demo.

Hello,

Welcome to this week’s progress update.

This was a shorter week than usual, as Monday had some family emergency and largely took the day off, but it was otherwise a pretty productive week, with many things moving forward and a lot of things to write about, so this is probably my longest update so far, but more technical than usual.

Hello and welcome to this week’s progress report.

This is also a bit of a special one, since it marks more than 6 months since I left AWS to double down on AutoSpotting development.

Without further ado, let’s dive right in!

Terraform updates

I started the week by working on bringing the AutoSpotting Terraform module in sync with the CloudFormation template, after previously it was rolling out an ancient release of AutoSpotting from October 2021, with lots of known issues.

AutoSpotting Architecture changes as result of my current customer onboarding

This week was another one largely focused on AutoSpotting development, most of the work resulting from the conversation I had with the relatively large enterprise customer I started to onboard last week to AutoSpotting.

Hi, Happy New Year, and welcome to the first weekly update from 2023 and the first one on Beehiiv!

For more context, this is a continuation of my older AutoSpotting, Cloudutil newsletters, and going forward will mirror my current LinkedIn newsletter which I’ve been using for weekly updates for the last few months after I left Amazon AWS. You can check out my previous posts on LinkedIn.

Hello, and welcome to this week’s update.

Without further ado, let’s dive right in!

LeanerCloud GUI work

Like I mentioned last week, I started the week by working for a couple of days on the new LeanerCloud GUI tool, that would hopefully remove some of the friction of adopting my tools for new users.

Current OpenTofu contributors vs. pledged FTEs

OpenTofu Github stats half a year after the fork.

After the recent layoffs at Google that impacted open source maintainers of some prominent projects, I was curious to see what’s the state of other projects where the community had to step up involvement after the initial authors ceased their Open Source contributions.

I saw a few people made similar comparisons for other forked projects in the past. As an infra guy myself, I immediately thought about OpenTofu, now that we’re more than half a year after the fork from Terraform, they recently had a massive release, and also had some interesting shenanigans with Hashicorp’s lawyers accusing them of stealing their precious IP.

Why I just declined a job offer from a billionaire friend

Fri, 03 May 2024 21:31:08 +0000

This is an expanded version of a LinkedIn post I wrote the other day.

The first email I read this week was this one I received from a billionaire friend, who wanted to talk to me on very short notice:

He’s the founder and CEO of a pretty large and well known company he still largely owns, and I respect him a lot so I won’t reveal his identity.

LinkedIn Outreach

I’ve recently started experimenting with cold outreach to drive some more sales, and I’ve been iterating on my messages.

Over the last weekend I asked for some feedback in one of the online communities I’m in, where I started a thread in which I asked how to make my messages less spammy and intrusive.

New AutoSpotting release - 1.2.0-2

Cristian Măgherușan-Stanciu

New AutoSpotting release

After less than 7 weeks from our previous AutoSpotting release, we’re happy to announce a new one, our biggest release so far in the entire 7 years history of AutoSpotting.

It brings over a dozen improvements in performance, reliability, correctness and ease of use, including the following major enhancements:

Proactive Spot instance launch on Spot terminations*, reducing the instance replacement time by avoiding the use of temporary On-Demand instances.*
Diversified failover to On-Demand instances during periods of high-demand of EC2 capacity provides even more resilience to Insufficient Capacity Errors(ICE) than the typical AutoScaling groups configured with a single instance type.
Automatically determine the Spot product for each AutoScaling group*, resulting in a simpler setup, correct instance type selection, accurate billing and higher diversification for Windows, RHEL and Suse Linux Spot instances.*
Supporting installation of AutoSpotting in any AWS region as its main region, reducing the complexity and networking costs of the previous cross-region setup.
Fixed a number of issues related to Security group configuration*, which sometimes caused Spot instances to fail to launch or start with incorrect Security Groups.*

This updated version of AutoSpotting is available on the AWS Marketplace and can be installed as usual using CloudFormation or Terraform.
