Why look beyond Fastly

Fastly provides a highly programmable content delivery network (CDN) and edge computing platform, offering real-time content delivery, API acceleration, and security for web applications. Its Compute@Edge environment enables developers to execute custom logic at the edge, supporting languages like Rust and JavaScript via WebAssembly. The platform is known for its granular control through Varnish Configuration Language (VCL) and comprehensive observability tools. Developers often choose Fastly for its performance and flexibility in building custom edge applications and optimizing content delivery pipelines.

However, organizations may seek alternatives for several reasons. Some may find Fastly's VCL configuration to have a learning curve compared to more abstracted solutions. Others might require a broader suite of integrated services beyond CDN and edge compute, such as extensive cloud infrastructure, managed security services, or specific regional coverage that better aligns with their global user base or compliance requirements. Cost considerations, particularly for smaller organizations or those with unpredictable traffic patterns, can also lead to evaluating other providers with different pricing models or bundled offerings. Additionally, some enterprises might prefer a provider with deeper integration into their existing cloud ecosystem or a more extensive range of developer tools and managed services.

  4. 4. Microsoft Azure CDN — Integrated with Azure ecosystem for global content delivery

    Microsoft Azure CDN is a global content delivery network provided by Microsoft, integrating with other Azure services. It delivers content to users by caching static and dynamic resources at strategically placed points of presence (PoPs) worldwide. Azure CDN offers features like dynamic site acceleration, intelligent caching, and integration with Azure Front Door for advanced routing and WAF capabilities. It supports various content types, including web objects, streaming media, and downloadable files. For organizations already using Microsoft Azure for their cloud infrastructure, Azure CDN offers a streamlined experience and unified billing. Developers can manage CDN configurations through the Azure portal, PowerShell, or Azure CLI, integrating with their existing Azure workflows.

    Best for: Organizations deeply integrated into the Microsoft Azure ecosystem, seeking a CDN solution that offers seamless integration with other Azure services for content delivery and web application acceleration.

  5. 5. Google Cloud CDN — High-performance content delivery leveraging Google's global network

    Google Cloud CDN leverages Google's global network infrastructure, which connects over 200 network edge locations, to deliver content with low latency. It is designed to work seamlessly with Google Cloud's HTTP(S) Load Balancing, enabling caching for both traditional web applications and microservices. Google Cloud CDN supports various caching strategies, invalidation, and custom origins. It is optimized for content delivered via Google Cloud Storage and Compute Engine. For edge computing, Google Cloud offers Cloud Functions and Cloud Run, allowing developers to deploy serverless applications that can respond to events or HTTP requests, extending functionality closer to users. Organizations using Google Cloud Platform can benefit from the integrated observability and management tools.

    Best for: Businesses operating within the Google Cloud Platform ecosystem that require high-performance content delivery, seamless integration with Google Cloud Load Balancing, and access to a global network.

How to pick

Selecting an alternative to Fastly involves evaluating your specific needs for content delivery, edge computing, security, and integration with existing infrastructure. Consider the following factors:

Cloud ecosystem integration

  • If your organization is heavily invested in a specific cloud provider: Opting for a CDN from that provider, such as Amazon CloudFront for AWS users, Microsoft Azure CDN for Azure users, or Google Cloud CDN for Google Cloud users, can simplify management, billing, and integration. These options often provide seamless interoperability with other services within their respective ecosystems.
  • If you require a vendor-agnostic solution: Cloudflare or Akamai offer robust services that operate independently of a specific cloud provider, allowing for multi-cloud or hybrid cloud strategies.

Programmability and control

  • For granular control and custom logic at the edge: Fastly's VCL and Compute@Edge are strong. Alternatives like Cloudflare Workers, AWS Lambda@Edge, or Akamai EdgeWorkers provide similar serverless edge computing capabilities, allowing you to run custom code closer to end-users. Evaluate the developer experience, supported languages, and integration with your existing CI/CD pipelines.
  • For simpler content caching without extensive custom logic: Standard CDN offerings from major cloud providers like Amazon CloudFront, Microsoft Azure CDN, or Google Cloud CDN might suffice, offering configuration through their respective consoles and APIs.

Security requirements

  • If advanced web application and API protection (WAAP) is a priority: Providers like Cloudflare and Akamai offer comprehensive security suites, including robust Web Application Firewalls (WAF), DDoS protection, and bot management, often integrated directly into their edge networks.
  • For integrated security within a cloud environment: AWS CloudFront with AWS WAF and Shield, Azure Front Door with its WAF capabilities, or Google Cloud CDN with Cloud Armor can provide layered security that aligns with your cloud architecture.

Performance and global reach

  • For global content delivery with high performance: All listed alternatives offer extensive global networks. Evaluate the number and location of Points of Presence (PoPs) relevant to your target audience. Providers like Akamai and Cloudflare are known for their broad global footprint and advanced routing optimizations.
  • For specific regional compliance or performance needs: Check if the alternative has PoPs in regions crucial for your business, ensuring data residency requirements can be met and latency minimized for local users.

Pricing and cost model

  • For predictable costs or bundled services: Some providers offer tiered plans or bundles that can simplify budgeting, especially for small to medium businesses. Cloudflare offers a free tier and various paid plans.
  • For usage-based pricing aligned with traffic: Most CDN providers, including AWS CloudFront, Azure CDN, and Google Cloud CDN, operate on a usage-based model (data transfer, requests), which can be cost-effective for fluctuating traffic but requires careful monitoring.
  • For enterprise-level engagements: Providers like Akamai often work on custom enterprise contracts, which can offer tailored services and support but require direct engagement with their sales teams.
