  • Where Apache Pulsar falls short: more components than Kafka: brokers, BookKeeper and ZooKeeper each need operating.
  • Where Azure DevOps falls short: first 5 users free applies to Basic plan only; Test Plans users are not included in free tier.

Where each one falls short

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

Apache Pulsar

  • More components than Kafka: brokers, BookKeeper and ZooKeeper each need operating
  • Correspondingly harder to run well, and the expertise is rarer than Kafka expertise
  • A much smaller ecosystem of connectors, tooling and hiring pool than Kafka
  • The architectural advantages only pay off at a scale most deployments never reach

Azure DevOps

  • First 5 users free applies to Basic plan only; Test Plans users are not included in free tier
  • Storage pricing increases per-GiB cost as volumes grow, with no volume discount threshold below $0.25

Answered from the vendors’ own pages

Apache Pulsar: Is Apache Pulsar free?

Yes, open source under the Apache Software Foundation.

Azure DevOps: How much does Azure DevOps cost?

Azure DevOps Basic plan is $6 per user per month after the first 5 users are free. Basic + Test Plans tier costs $52 per user per month. Azure Pipelines add-on for extra parallel jobs costs $40 per job for Microsoft-hosted runners and $15 per job for self-hosted runners.

Apache Pulsar: Pulsar or Kafka?

Pulsar separates storage from compute and covers queuing and streaming in one system. Kafka has a far larger ecosystem and hiring pool. Most teams should have a specific reason before choosing Pulsar.

Azure DevOps: Is there a free tier for Azure DevOps?

Yes, Azure DevOps includes 5 free users on the Basic plan. Additional free allocations include 1,800 free minutes per month on Azure Pipelines with a free parallel job, 2 GiB free storage on Azure Artifacts, and free access for Visual Studio subscribers and Stakeholders with limited functionality.

Source
Apache Pulsar: Why does separated storage matter?

Brokers hold no data, so adding or replacing one requires no rebalancing, and storage can grow without adding serving capacity.

Azure DevOps: What does the Basic + Test Plans tier add to Azure DevOps?

The Basic + Test Plans tier adds test planning and execution capabilities, browser-based testing, and centralized reporting features. This tier costs $52 per user per month compared to $6 per user for the Basic plan.

Source
Azure DevOps: How is Azure Artifacts priced?

Azure Artifacts provides 2 GiB of free storage, then charges $2 per GiB for 2-10 GiB, $1 per GiB for 10-100 GiB, $0.50 per GiB for 100-1,000 GiB, and $0.25 per GiB for over 1,000 GiB.
