2 Best APIs for Global CDN in Nigeria

Cloudflare R2 is an S3-compatible cloud object storage service from Cloudflare that eliminates egress fees — the charges applied when data is transferred out of storage. This zero-egress-fee model is the defining financial characteristic of R2 and the primary reason developers choose it over AWS S3 for workloads where data is frequently read, downloaded, or served to end users. Storage costs in R2 are $0.015 per GB per month for Standard storage, with no additional charges for data retrieval or outbound bandwidth. The elimination of egress fees is particularly significant for media-heavy applications, public file distribution services, and any application that serves stored content directly to users at scale. On AWS S3, egress is charged at $0.09 per GB beyond the free tier for US regions. For an application serving 100TB of data per month to users, egress alone would cost approximately $9,000 on S3. On R2, the same 100TB of serving costs $0. This difference makes R2 the economically rational choice for high-egress workloads where storage and data serving costs are significant. R2 implements the Amazon S3 API, meaning existing code written for AWS S3 works with R2 by changing the endpoint URL from the standard AWS S3 endpoint to the account-specific R2 endpoint and updating credentials to R2 access keys. AWS SDKs (in all languages), the AWS CLI, and S3-compatible tools like rclone and s3cmd all work with R2 without code changes beyond configuration. For Nigerian developers with existing S3 codebases, migrating to R2 for cost savings requires minimal engineering effort. R2 buckets can be connected to Cloudflare's global CDN through custom domain configuration, enabling R2 objects to be served directly through Cloudflare's network of over 300 edge locations worldwide. When R2 is fronted by Cloudflare CDN, users around the world receive cached content from the nearest Cloudflare edge, while only cache misses reach the R2 origin. For Nigerian users, Cloudflare has edge locations in Lagos (among other African cities), meaning R2-hosted content served through Cloudflare CDN can be retrieved with low latency by Nigerian users. R2 supports Cloudflare Workers integration, allowing serverless JavaScript code to intercept, transform, and respond to requests for R2 objects. A Cloudflare Worker can apply access control logic, perform on-the-fly transformations, generate dynamic responses incorporating R2 object content, or log request metadata — all at the edge without involving origin servers. Nigerian developers building edge-first applications using Cloudflare Workers can use R2 as the persistent storage layer accessible directly from Worker code using the R2 binding. Object versioning in R2 allows multiple versions of an object to be retained, protecting against accidental deletion or overwrite by enabling recovery of previous versions. Combined with R2's lifecycle policies for transitioning objects to Infrequent Access storage class or deleting them after specified durations, R2 provides the standard object management capabilities expected of a production storage system. R2 currently stores data in one of two jurisdictions: automatic (Cloudflare distributes across their global infrastructure) or EU (data stored only in European Union data centers). For Nigerian applications with NDPR data localization concerns, R2's automatic jurisdiction means data may reside in US or EU data centers — a consideration for applications with strict local data residency requirements. Presigned URL equivalent functionality in R2 is provided through R2's temporary credentials and signed URL capabilities, allowing applications to generate time-limited URLs for private object access. This is essential for Nigerian applications serving user-uploaded private content — medical records, financial documents, personal photos — where objects must not be publicly accessible but need to be temporarily shareable with specific authenticated users. For Nigerian startups, media platforms, and file hosting services that need reliable S3-compatible object storage without the unpredictable egress cost that makes scaling storage-heavy applications expensive, R2 offers the combination of S3 API compatibility, Cloudflare network integration, and zero-egress pricing that makes it a strong default choice.
