Amazon CloudFront

Pros

• The network is very large, with more than 750 PoPs plus over 1,140 PoPs embedded inside ISP networks.
• Data transfer from AWS origins such as S3 and EC2 to CloudFront costs nothing, which lowers costs for workloads hosted on AWS.
• Flat-rate plans start at $15 a month with no overage charges, which makes bills predictable.
• It has strong compliance coverage, including PCI-DSS Level 1, HIPAA, SOC, ISO and FedRAMP Moderate.
• Two tiers of edge compute are available: CloudFront Functions at $0.10 per million invocations and Lambda@Edge for heavier code.

Cons

• G2 and Capterra reviewers report complex configuration and a steep learning curve for people new to AWS.
• Capterra-network reviewers rate customer support poorly, around 3.4 out of 5.
• Flat-rate plans lack some features, such as real-time logs, dedicated IP SSL and continuous deployment, and going over the allowance reduces performance.
• Dedicated IP SSL at $600 a month and Anycast Static IPs at $3,000 a month are expensive extras.
• Users on AWS re:Post and GitHub report cache invalidations that occasionally hang for hours or time out during deploys.

AWS Lambda

Pros

• The permanent free tier of 1 million requests and 400,000 GB-seconds a month makes low-traffic workloads nearly free.
• It scales automatically, and G2 reviewers often praise this.
• It triggers natively from other AWS services and sends logs, metrics, and traces to CloudWatch and X-Ray automatically.
• Functions run on dedicated Nitro-based compute, and the service holds SOC, HIPAA, PCI, and ISO certifications.
• SnapStart and Provisioned Concurrency give options for reducing cold-start latency.

Cons

• Each invocation is capped at 15 minutes and 10 GB of memory, so it does not suit long or heavy jobs.
• Function code plus layers is limited to 250 MB unzipped.
• Since August 2025 the initialization phase is billed, which raises costs for functions with slow startup such as Java or .NET.
• Reviewers say debugging is hard because they depend on logs in an abstracted environment.
• Costs can be hard to predict once third-party tools and architectural complexity are added.
