Cloudflare to Azion Migration Guide
A comprehensive technical reference for engineering teams. Includes detailed product mapping tables, code comparison snippets, configuration examples, and step-by-step migration procedures.
Zero cold starts
Consistent first-request performance with no cold start latency. Functions execute immediately on Azion's distributed infrastructure.
Extended execution time
Up to 5 minutes of CPU time per execution versus 30-second limits. Run complex workloads without splitting logic.
Native SQL Database
Built-in distributed SQL with vector search, ACID compliance, and global read replicas—no external database required.
Migrate without rewriting your code
Azion provides compatible APIs for Cloudflare services. Workers code runs on Functions with minimal changes, KV data migrates to KV Store, and R2 buckets sync to Object Storage using S3-compatible APIs.Complete Guide Migration
Global performance
Sub-30ms latency across 120+ locations worldwide. Distributed architecture ensures fast response times for users everywhere.
Transparent pricing
Pay only for what you use with no hidden fees, no egress charges between services, and no mandatory long-term contracts.
Unified platform
Build, store, and secure applications on one platform. Functions, Storage, SQL Database, WAF, and DDoS protection work together seamlessly.
Frequently Asked Questions
Is KV Store compatible with Cloudflare Workers KV?
Yes. KV Store provides a compatible API with Cloudflare Workers KV, making it easier to migrate existing applications or use familiar patterns.
How do I migrate Workers code to Azion Functions?
Azion Functions supports TypeScript and JavaScript with web-standard APIs and Node.js polyfills. You can deploy using the Azion CLI, Git integration with continuous deployment, or frameworks like Next.js, Vue, React, Angular, Gatsby, and Astro. Most Workers code requires minimal changes.
What execution time limits does Azion Functions support?
Functions support up to 5 minutes of CPU time per execution and bundle sizes up to 20 MB—compared to Cloudflare's 30-second CPU time limit. This allows you to run complex workloads without splitting logic across multiple functions.
Are there cold starts on Azion Functions?
No. Azion Functions execute immediately on distributed infrastructure with zero cold start latency. You get consistent first-request performance without the unpredictable delays common in serverless platforms.
What latency can I expect globally?
Sub-30ms latency across 120+ locations worldwide. Azion's distributed architecture ensures fast response times for users everywhere, with automatic routing to the nearest edge location.
How does pricing compare to Cloudflare?
Azion offers transparent pay-as-you-go pricing with no hidden fees, no egress charges between services, and no mandatory long-term contracts. You pay only for what you use, and you get $300 in free credits valid for 365 days to start testing.
Is there vendor lock-in with Azion?
No. Azion uses S3-compatible APIs for Object Storage, standard web APIs for Functions, and portable code patterns. You can migrate away at any time without proprietary dependencies or mandatory contracts locking you in.
What support is available during migration?
Comprehensive documentation, step-by-step migration guides, and technical references are available. Plus, you get $300 in free credits valid for 365 days to test and validate your migration with no credit card required.
Can I run both platforms in parallel during migration?
Yes. You can run Cloudflare and Azion simultaneously and gradually shift traffic using DNS configuration. This allows for testing, validation, and a smooth transition without service interruption
