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 ...

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.

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 ...
