I like how easy it makes deployment of applications - you can spin up servers with just one command! It also has great support in terms of API management which helps to integrate easily into existing infrastructure (AWS). We are using armory as part our CI/CD pipeline at work where we use Jenkins+SpinachCI + Gitlab CE+. The main benefit here was ease of integration & configurability across multiple cloud providers such AWS ECS instances or GCP Container Engine VMs etc.. There were some minor issues faced while working around this but nothing majorly negative so far!! Have used Spinachtci recently too when deploying Docker containers from GitHub repo onto Cloud Foundry micro services built by us within IBM Bluemix environment.- Deployment speed between different environments e g Dev -> QA / Prod via Bluepill container image deployed directly through docker compose file without any manual steps required after build stage done successfully-.
