Where each one falls short

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

Apache Solr

  • XML-heavy configuration and a developer experience that feels dated beside newer engines
  • SolrCloud depends on ZooKeeper, adding a component Elasticsearch removed years ago
  • Smaller mindshare now, so newer tutorials, hiring and integrations favour Elasticsearch
  • Considerably heavier than a purpose-built application search engine

IBM Cloud

  • The USD 200 starter cloud credit is valid for 30 days only
  • The larger promotional credits are time boxed: USD 1,000 for Bare Metal Servers for VPC over 120 days, USD 2,500 for Power Virtual Server over 90 days, and USD 5,000 for Backup and Recovery over 90 days
  • The USD 5,000 Backup and Recovery promotion is valid for new clients only and requires a checkout promo code
  • The listed promotions carry an expiry date of 31 December 2026
  • Beyond the free tier the account is pay as you go, so cost tracks usage with no published cap
