I noticed that you’re using container services from AWS and GCP. Do this mean that you use less configuration management tools (such as Puppet/Chef/Ansible/Salt)? Though I note you use Cloud Formation on AWS.
Many moving to the cloud perceive this as requiring the rearchitecting of their applications into microservices. Are you finding any downside to having a monolithic web app?
Could I ask what build pipeline (CI/CD) tool you’re using?
