Alternatives to Google Cloud Storage
Amazon S3 is the default alternative for multi-cloud or AWS-native teams. S3's ecosystem—presigned URLs, event triggers, Lambda integrations, third-party tooling—is larger than GCS and often the practical choice when the team isn't committed to Google Cloud.
Azure Blob Storage is the Microsoft-ecosystem alternative for organizations standardized on Azure where GCS's Google Cloud integration provides no benefit. The right choice when Azure Active Directory, Compliance Manager, and Azure networking are the primary governance framework.
Backblaze B2 is the cost-first alternative for backups, archives, and cold storage that doesn't need GCS's analytics integrations. At ~$0.006/GB (vs GCS at $0.02/GB) for storage plus free egress to Cloudflare, it's the cheapest durable option for infrequently accessed data.
