-The easy of use-the good documentation.-Easy to deploy in AWS using EC2 auto scaling feature.-Good support from their customer success manager Mr Hadi Salami who is very responsive.-Excellent project management team which can understand my needs at an early stage and help me by providing valuable feedback regarding any change that will be coming next or even prior before its released as well! I have been working since 2013 on deploying serverless applications into production environment to make them more robust and scalable without having worry about managing infrastructure related stuffs like servers provisioning etc., it's great experience so far but what i didn't liked was deployment process where once application gets deployed it requires manual intervention to turn "online" otherwise we are always running behind schedule (at least during development). We're solving this problem now through S3 events notifications which makes deployment much easier than doing things manually all the times while waiting until our apps get fully tested/reviewed by QA engineers / PMT members etc... We use agile staes to create reproducible environments that are easy deploy across our cloud providers (AWS/GCP). The ability of having multiple versions in one environment is very powerful as well! It's not perfect yet but we're working hard at it :) Currently using kubernete infra-structure so far I like best how you can easily add your own components without any changes required from agilestack team!
