Stratospheric 1.10 Release 🚀

This week, we published another update to Stratospheric - From Zero to Production with Spring Boot and AWS.

The release of Spring Boot 3.0 marks a new era of developing applications with the Spring Framework. 4.5 years after the release of Spring Boot 2.0, we’re now looking into a bright future and can make the most of Spring Framework 6, ...

Stratospheric 1.9 Release 🥳

This week, we released version 1.9 of Stratospheric - From Zero to Production with Spring Boot and AWS. With our current Stratospheric online course recording efforts, we added a ready-to-use blueprint for an operational Amazon CloudWatch dashboard for our Spring Boot application. Furthermore, we fixed some inconsistencies in our manuscript. Finally, as our complementary online course is making good progress, we now refer to it as part of the introduction and outro. You can read more about the new release in this blog post on ...

New Stratospheric Blog Post on Faster Amazon ECS Container Deployments

This week, we published a new Stratospheric blog post on how we achieved faster Amazon ECS Container deployments. So, if you're running containerized applications on AWS you might want to check this out. While that specific example uses the AWS CDK in its Java incarnation the general ideas and settings are generally applicable and therefore should easily translate to other languages and environments, too.

Stratospheric Online Course: Early-Bird Offer

Earlier his week, we finally released the first iteration of the Stratospheric Online Course - a companion course to our ebook "Stratospheric - From Zero to Production with Spring Boot and AWS"! Having just returned from Spring I/O 2022 in Barcelona - where, incidentally, the authors of Stratospheric met in person for the first time - I can say there are quite a few exciting things in store for Spring Boot and Spring in the near future, particularly when it comes to ...

Stratospheric – 1.6 Released: AWS CDK Bootstrapping 🏗

This week, we released version 1.6 of Stratospheric - From Zero to Production with Spring Boot and AWS. The main reason behind this release is that we somehow entirely missed talking about an important topic: Bootstrapping an AWS environment for the AWS CDK. You may have already run into this issue when trying to deploy one of our AWS CDK stacks: Has the environment been bootstrapped? Please run 'cdk bootstrap' We've now added a dedicated section on the AWS environment bootstrapping and explained the why ...

Optimising Docker Image Sizes: “Self-extracting” Node.js Applications

As a follow-up on last week's article on tools for inspecting Docker images, and Docker image sizes in particular, today I'd like to introduce another - more custom - approach for reducing the size of Docker images for production deployments. As a means of shaving off an additional 50 MB from the packaged application in question I came up with an idea somewhat reminiscent of the self-extracting archives of yore (of the WinRAR and 7-Zip flavours, for instance) for reducing the size ...

Tools for Inspecting Docker Images

Recently, I needed to inspect a Docker image in order to optimize its size for distribution and deployment on an ARM-based industrial microcontroller with rather tight bandwidth constraints. Once deployed at customer sites, these controllers typically don't have an Internet connection but still need to be updated occasionally, via the local network in that case. Since there's no guaranteed minimum network speed in this type of environment, yet software updates still have to complete within a relatively short period of time, optimizing ...
