WHY ARE CLOUD DEVELOPMENT ENVIRONMENTS SPIKING IN POPULARITY, NOW?
More and more tech companies are using cloud development environments (CDEs). CDEs are remote development environments, where code is run on more powerful machines in the cloud. Generally, these allow code to be built faster, reduce local machine-specific errors, and allow collaboration to shine. There are a few reasons behind why CDEs are rising in popularity, such as codebases getting larger, monorepos becoming more popular, and plateaus in laptop computing power.
