Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Lambda (AWS Serverless)

  • Billed on two axes at once, $0.20 per million requests plus $0.0000166667 per GB-second of duration, so memory settings change the bill as much as traffic does
  • Provisioned concurrency, used to avoid cold starts, is charged separately at $0.0000041667 per GB-second whether or not the function runs
  • Ephemeral storage beyond the included 512 MB is metered
  • Lambda@Edge costs $0.60 per million requests, three times the standard request rate
  • VPC use and cross-region data transfer carry EC2 charges on top

JetBrains IntelliJ IDEA

  • High memory consumption and slower startup time compared to lightweight editors like Visual Studio Code
  • Refactoring can sometimes increase code line count and doesn't effectively support all modern programming languages
  • Occasionally misses dependencies between files requiring full rebuilds for consistency
  • Expensive subscription costs for Ultimate edition compared to open-source alternatives like Eclipse
  • Not all class name references are updated reliably when using search and replace functionality
