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.

Bitbucket: Can I self-host Bitbucket?

Yes. Bitbucket Data Center is available for self-hosted deployments starting at $2,300 per year. It provides teams with complete control of their environments and disaster recovery capabilities.

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.

Bitbucket: How many build minutes do I get with Bitbucket Pipelines?

Free plan includes 50 build minutes per month. Standard plan ($3.65/user/month) includes 2,500 pooled build minutes. Premium plan ($7.25/user/month) includes 3,500 build minutes. Additional minutes can be purchased in $10 packs for 1,000 minutes.

Source
Bitbucket: Does Bitbucket integrate with Jira?

Yes. Bitbucket integrates natively with Jira, allowing you to track associated builds and deployments to Jira work items. It also integrates with Slack, Compass, and VS Code.
