Cloudcraft – Cloud Architecture Diagrams and Visualisations

After recently having written about AWS cloud visualisation and management tools such as CloudMapper and Vantage I was made aware of yet another such tool by Sebastian Reuße: Cloudcraft allows you to not only visualise your AWS cloud architecture with beautiful as well as somewhat playful isometric infrastructure diagrams reminiscent of turn-based strategy games but also provides live connectivity with your actual AWS infrastructure and so-called "smart" components. Using these features you don't have to manually draw and recreate your existing infrastructure in ... Read more

Vantage – A Unified AWS Console

In last week's blog post I casually mentioned that out-of-the-box with AWS there's no single unified console providing you with an overview of your deployed infrastructure. Thankfully, there's Vantage - a centralized dashboard that provides you with such an overview and cost transparency across AWS regions and accounts through views, global search, and actionable insights. Up to $500 in monthly AWS spend Vantage is free. Beyond that there are Pro and Business plans at a monthly price of $50 and $250, respectively. Read more

CloudMapper: An AWS Visualisation Tool

CloudMapper is an AWS visualisation tool that's highly useful for getting an overview of your AWS infrastructure and network setup. Depending on the number of services, instances, VPCs, and subnets used, getting lost is quite easy, especially when considering that out-of-the-box with AWS there's no single unified console from which to get an overview of your deployed resources but rather a multitude of consoles, one for each AWS service. Therefore, keeping track of your infrastructure and keeping your costs in check can be ... Read more

Stratospheric – Three New Chapters!

Last week, we released the 3rd iteration of our eBook Stratospheric - From Zero to Production with Spring Boot and AWS. Roughly two months have passed since the last release in December 2020. We hope that we've made good use of this time by adding a few more chapters, as well as by improving and "refactoring" some of the already existing content. ​ The latest release contains these new chapters: Designing a Deployment Project with CDK: Building upon our First Steps with CDK we'll go ...

(Deutsch) Lösung für die COVID-19 Pandemie: Schnelltests als Zugangsberechtigung

Sorry, this entry is only available in German.Contrary to my usual writing habits the remainder of this post will be in German. The reason for this is that although the subject most certainly is of interest to everyone the specifics of the solution outlined in the following mostly apply to the current COVID-19 situation in Germany and my personal experience with that situation. The article therefore is mostly relevant to a German audience. If you're interested in discussing the potential for ... Read more

Five Articles on Software Quality and Design Patterns

This week I'd like to point you to five articles I previously posted on this blog and from which I think that they're as relevant as they were at the time. The first three are about general software design principles, software architecture and software quality while the final two refer to specific best practices and common design patterns for Angular: Writing Disposable Code, Not Reusable Code (November 06, 2016) What Causes Over-engineering and How Can You Prevent It? (April 16, 2017) Less Is More ... Read more

Image Compression Utility: Squoosh

When working with images on web applications and websites optimising images and reducing their download size is a quick win in terms of optimising page and app load times. There are plenty of image compression utilities out there - both web apps and tools for local installation. Recently, I've tried out several of those again because I wanted to reduce the overall load time of this website and according to website audit tools such as Lighthouse image sizes definitely was an area ...

Second Version of Stratospheric – From Zero to Production with Spring Boot and AWS

This release contains these new chapters on IAM, local development, and automated deployments: ​ Managing Permissions with IAM - this chapter gives an overview of the concepts we can use with AWS in order to secure our resources and to authorize both individuals and applications to access them. Local Development Setup - this chapter explains how we can develop our cloud-based Todo application ... Read more

Tools for Working With CSS Grid Layouts and Flexbox

CSS Grid Layout and CSS Flexible Box Layout, commonly known as Flexbox, are powerful techniques for implementing flexible grid and column- or row-based layouts with CSS. These two techniques enable designers and web developers to accurately and fluidly position elements and content on web pages and web applications. While Flexbox (see A Complete Guide to Flexbox by CSS-Tricks) predominantly works along a single principal dimension, called the main axis or flex direction (either row or column), and therefore essentially is a one-dimensional ...
