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

Google Cloud Platform

  • The $300 Free Trial credit expires 90 days from signup, whichever comes first with spending it
  • Free Tier Compute Engine is limited to one non-preemptible e2-micro instance per month and only in the us-west1, us-central1 or us-east1 regions
  • Free Tier Compute Engine includes only 30 GB-months of standard persistent disk and 1 GB of outbound North America data transfer per month
  • Free Tier Cloud Storage covers 5 GB-months of regional storage in US regions only, 5,000 Class A and 50,000 Class B operations per month
  • Free Tier outbound data transfer allowances exclude destinations in China and Australia
  • Compute Engine resources are governed by allocation quotas that require a quota increase request to exceed
