Netflix is a SaaS company, not a PaaS company — though the full answer needs a bit more nuance than that. From where you're sitting, watching a show on your laptop or TV, Netflix behaves exactly like SaaS: you pay a monthly fee, open an app, and use the software without ever installing, managing, or maintaining anything yourself. PaaS is a completely different category built for developers, not viewers, so Netflix's actual product doesn't belong there at all.
Here's where people get tripped up, though: Netflix runs on Amazon Web Services, and AWS is famous for its PaaS and IaaS offerings. So does that make Netflix a PaaS company too? Not quite. It just means Netflix is a massive customer of PaaS and IaaS, not a provider of it.
SaaS, PaaS, and IaaS — A Quick Refresher
Cloud services are usually split into three layers:
- IaaS (Infrastructure as a Service): raw computing power — servers, storage, networking — rented instead of owned. AWS EC2 and Azure Virtual Machines live here.
- PaaS (Platform as a Service): a ready-made environment for building and deploying applications, without managing the servers underneath. Heroku and Google App Engine are classic examples.
- SaaS (Software as a Service): a finished application you use directly, with zero involvement in the infrastructure or platform underneath. Gmail, Slack, and Netflix all sit here.
These layers stack on top of each other. SaaS is typically built using PaaS, and PaaS runs on IaaS.
Why Netflix Is SaaS From the User's Side
Netflix checks every box of the SaaS definition:
- It's accessed entirely through a browser or app, with nothing meaningful installed locally.
- It runs on a subscription model — you pay monthly, or as part of a bundle, for continued access.
- Netflix, not you, handles every bit of maintenance: servers, updates, security, scaling during a big finale drop.
- You can't customize the underlying code or deploy anything on it. You just consume the product.
That last point is really the dividing line. PaaS exists so other people can build things on top of it. Netflix doesn't let you build anything — it hands you a finished, polished product and nothing more.
Netflix Isn't a "Typical" B2B SaaS, Either
Most SaaS examples people reach for — Salesforce, HubSpot, Slack — are B2B tools built to make a business more productive. Netflix is B2C entertainment. It's still SaaS by definition (cloud-delivered, subscription-based, fully managed), just in a subcategory sometimes called consumer SaaS, alongside Spotify and Disney+.
The Real Twist: Netflix Runs on PaaS and IaaS Internally
This is where the question gets genuinely interesting. While Netflix sells you a SaaS product, its engineering team is one of the most sophisticated users of AWS's infrastructure on the planet. Netflix runs its backend almost entirely on AWS — compute, storage, databases, content delivery — and famously built tools like Chaos Monkey to stress-test that setup. Internally, Netflix behaves like a company built on top of a PaaS/IaaS stack, even though what it sells you is pure SaaS.
That's a pattern worth remembering: a company's category isn't fixed. It depends on which side of the transaction you're looking at. Netflix-the-product is SaaS. Netflix-the-engineering-org is one of the biggest PaaS/IaaS customers around.
Where Netflix Fits, Layer by Layer
| Layer | Does Netflix provide it? | Does Netflix use it? |
|---|---|---|
| SaaS | Yes — the streaming app itself | — |
| PaaS | No | Yes, indirectly through AWS |
| IaaS | No | Yes, heavily (AWS compute & storage) |
Why This Distinction Actually Matters
This isn't just trivia for a quiz night. If you're building a startup, understanding the SaaS/PaaS/IaaS split tells you what you're actually selling and who you're actually competing against. A media platform like Netflix competes with other SaaS-style entertainment services, not with AWS. Meanwhile, a company like Heroku or Vercel competes at the PaaS layer, selling to developers rather than viewers.
Mixing these up in a pitch deck or a competitive analysis is a fast way to confuse investors and customers alike — know which layer your product actually lives in before you describe it to anyone.
