The secret here is to not learn everything but rather learn a technology from each category. This will give you experience in the end-to-end while also giving you something to compare every other technology against.
Worth mentioning webAssembly
AWS CloudFormation
GCP Deployment Manager
Azure Resource Manager
Next.js
Load balancing
AWS Elastic Load Balancing
Google Cloud Load Balancing
Azure Load Balancer
Didn't want to branch further but can split NoSQL in to four categories:
key-value, graph, column, document.
DNS
ECS
