Coming from an environment that uses lots of AWS resources to handle scaling requirements across different kinds of workloads on different linked accounts, one of the challenges we faced was to communicate and collaborate efforts and its impacts on cost efficiency. Typically our best environment isn’t the product of a singular design effort at the individual level, but many times emergent based on differing opinions and trials to assert assumptions in practice. We built a tool, https://liquidsky.singtel-labs.com, to help with this.
