Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

C3 AI Suite

  • The commercial model bundles software with heavy professional services, so the licence line in the quote understates the first-year cost by a wide margin and budgets set from the licence alone overrun.
  • Applications are written against C3 proprietary types, so nothing built on the platform ports to a generic Spark or Databricks stack without a rewrite, which makes exit expensive after two or three years.
  • Contracts have historically been large multi-year commitments with a small number of very large customers, which means pricing is negotiated case by case and small buyers get little leverage.
  • Skills are scarce outside C3 itself, so hiring an engineer who already knows the platform is hard and the customer stays dependent on the vendor for extensions.
  • Pre-built applications need substantial configuration against the customer data model before they produce anything, so the marketing claim of a packaged app understates the integration work by months.

Fastly

  • Bandwidth is priced per region, and delivery to India, Africa and South Korea is $0.28 per GB against $0.12 in North America and Europe
  • The same traffic therefore costs more than twice as much depending on where the audience is, which is invisible until the bill arrives
  • The free allowance is 100 GB of bandwidth and 1M requests a month
  • Requests are billed separately from bandwidth, at $0.01 per 10,000 above the first million
  • High volume rates past 50 TB are not published and require contacting sales

Answered from the vendors’ own pages

C3 AI Suite: Does C3 publish pricing?

No. Everything is quoted, and the shape of the deal, pilot then subscription, means the first number you see is for a proof of value rather than the platform.

Fastly: Does Fastly charge based on usage or a flat monthly fee?

Fastly operates on a usage-based model with volume discounts. They offer a free tier with 100 GB bandwidth and 1M requests for experimentation, then customers pay per unit consumed with tiered discounts as consumption increases.

C3 AI Suite: Can it run in a classified environment?

Yes. C3 supports air-gapped and government cloud deployments, including FedRAMP-authorised environments, which is a large part of why defence buyers choose it.

Fastly: What are Fastly's main service packages and their costs?

Fastly offers Network Services Packages ($1,500-$6,000/month baseline), Security Packages (custom pricing), Compute Packages ($500/month entry level), and Observability Packages ($1,500/month entry level). Enterprise solutions include custom quotes for high-volume deployments.

Source
C3 AI Suite: Do we own the models we build?

You own the models and the data. The application logic is written in C3 types, so the artefacts are portable in principle and impractical to move in practice.

Fastly: Can I start using Fastly for free?

Yes, Fastly offers a free tier with generous allowances for experimentation including 100 GB bandwidth and 1M requests. You can start building free and only pay when you use additional resources.

Source
Fastly: Are there surprise overage charges with Fastly?

Fastly advertises predictable pricing with no surprise overages. The pricing structure is designed to be transparent as consumption grows.
