  • Both are free.

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

Visual Studio

  • Community edition is free only for individual developers, classroom use, academic research and open-source contribution, not general commercial use
  • Monthly subscriptions are $45 per user per month for Professional and $250 per user per month for Enterprise, and do not include perpetual use rights the way annual Standard subscriptions do
  • A standalone perpetually licensed Visual Studio Professional 2022 costs $499 as a one-time purchase, separate from the subscription tiers

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.

Visual Studio: What are the pricing differences between subscription types?

Standard subscriptions include access to more benefits, such as Azure dev/test pricing, monthly Azure individual credit, software and download access, services, training, and support. Monthly subscriptions offer flexibility but fewer benefits.

Source
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.

Visual Studio: Are discounts available for startups?

There aren't any discounts available to start-ups, however an unlimited number of users within an organization can use Visual Studio Community for specific scenarios like open source work.

Source
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.

Visual Studio: Who can use Visual Studio Community for free?

In non-enterprise organizations, up to five users can use it. Enterprise organizations (greater than 250 PCs or greater than $1M annual revenue) cannot use it beyond academic/open-source scenarios.

Visual Studio: What's the renewal pricing structure?

Enterprise standard renews at $214.09/month (after initial $499.92); Professional at $66.59/month (after $99.99).
