It's simple to use because it has an intuitive UI that allows you not only manage your clusters but also interact with them in real time using web sockets or RPC calls from other languages like Java/Python etc..
I've used this software so far as part of my work at our startup where we were building out some microservices which required us managing multiple Docker containers across different cloud providers (AWS EKS). The product works well when there are very few nodes within each container service provider since then they can easily be identified by their node ID instead having many services running under one account - however if too much traffic comes into these pods i have seen issues arise due lack resources available causing downtime during peak times such as weekends! We had problems identifying all instances belonging together hence creating several accounts just cause someone forgot about deleting old ones was quite costly especially considering how long ago those deleted projects could still exist somewhere deep inside AWS S3 storage system.
