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.

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.

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.

Cloudinary: What is the difference between Cloudinary Plus and Advanced plans?

Plus plan costs $99/month (or $89/month annually) and includes S3 backup, auto-tagging, and expedited support for up to 3 users across 2 accounts with 225 credits. Advanced is $249/month ($224/month annually), adds custom domain (CNAME) and SSL options for 5 users across 3 accounts with 600 credits.

Source
Cloudinary: Does Cloudinary offer annual billing discounts?

Yes. Cloudinary's annual billing provides discounts: Plus plan is $89/month when billed yearly (versus $99/month monthly), and Advanced plan is $224/month when billed yearly (versus $249/month monthly).
