Where each one falls short

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

Apache Flink

  • Genuinely difficult: event time, watermarks and state backends are a real conceptual load before anything works
  • Operationally heavy — job managers, task managers, checkpoint storage and state size are all yours to run and tune
  • State grows with the workload, and large state changes recovery time and cost significantly
  • Overkill where a scheduled batch job would answer the same question

Cloudinary

  • Free plan includes only 25 monthly credits and is limited to 3 users and 1 account
  • Enterprise plan pricing is custom; rates not published
  • Monthly billing is more expensive than annual; yearly plan is $89/month for Plus ($224/month for Advanced)

Answered from the vendors’ own pages

Apache Flink: Is Apache Flink free?

Yes, open source under the Apache Software Foundation. Managed services such as Amazon Managed Service for Apache Flink are billed separately.

Apache Flink: Flink or Kafka?

They are complementary rather than alternatives. Kafka moves and stores events; Flink computes over them with windowing, joins and durable state.

Cloudinary: How does Cloudinary's credit system work?

Cloudinary credits measure usage: one credit equals 1,000 transformations, or 1 GB managed storage, or 1 GB image bandwidth, or 2 GB video bandwidth. The free plan grants 25 credits per month, Plus plan 225 monthly credits, and Advanced plan 600 monthly credits.

Apache Flink: What is event-time processing?

Computing based on when an event actually occurred rather than when it arrived. It is what makes results correct when data is late or out of order, and it is the main reason Flink is harder than it looks.
