Both AWS Lambda and Zoho Catalyst let you run code without managing servers. They are built for different kinds of teams, so the right choice depends less on features and more on what you already use.

What each one is

AWS Lambda is a general-purpose function service inside Amazon Web Services. It runs your code in response to events and connects to the rest of AWS: storage, databases, queues, API gateways and more.

Zoho Catalyst is a full-stack serverless platform from Zoho. Functions are one part of it. It also offers a data store, file storage, authentication, and hosting for web apps, all in one console. It is designed to extend and connect Zoho products such as CRM, Books and Desk, but it can be used on its own.

Side by side

| | AWS Lambda | Zoho Catalyst | |---|---|---| | Positioning | Building block inside a very large cloud | Integrated platform with its own services | | Best known for | Event-driven backends, wide AWS integration | Extending Zoho apps, quick full-stack builds | | Learning curve | Steeper: many services to combine | Gentler: one console, fewer pieces | | Ecosystem | Very large, with many partners and tools | Smaller, focused on the Zoho world | | Billing | Pay per request and compute time | Usage-based, with a free tier |

Check the official pricing pages of AWS and Zoho Catalyst before you decide. Prices, free tiers and limits change, so we do not quote them here.

When AWS Lambda is the better fit

  • Your systems already run on AWS, or you plan to move there.
  • You need fine control over networking, security and scaling.
  • You will connect many other cloud services around the function.
  • You have, or can hire, engineers who know AWS well.

When Zoho Catalyst is the better fit

  • Your business runs on Zoho (CRM, Books, Desk, Creator) and you want custom logic that plugs straight into it.
  • You want a smaller platform that a small team can learn quickly.
  • You prefer one vendor and one bill for functions, data and hosting.
  • Your use case is business automation more than large-scale infrastructure.

Questions to ask before you choose

  1. Which systems must the function talk to? Choose the platform closest to them.
  2. Who will maintain it in two years? Pick a stack your team or partner knows.
  3. Where must your data live? Check regions and your compliance needs, including India's data protection rules.
  4. How will costs grow? Estimate your monthly volume and test it on each pricing calculator.
  5. How hard is it to leave? Keep business logic portable and avoid unnecessary lock-in.

The practical answer

If you are a Zoho customer automating Zoho workflows, Catalyst is usually the shorter path. If you are building a broader product or already live in AWS, Lambda is usually the safer long-term base. Many companies use both: Catalyst close to Zoho, Lambda for everything else.

FAQ

Is Zoho Catalyst cheaper than AWS Lambda? It depends on volume and what else you use. Compare both calculators with your own numbers.

Can Catalyst replace AWS? For small and mid-sized business apps, often yes. For large, complex infrastructure, AWS offers far more services.

Which is easier for beginners? Catalyst is generally simpler to start with because everything sits in one console.

Can I use both? Yes. They can call each other over standard HTTP APIs.
