Imagine you are deploying your app without setting up a single server.
No backend infrastructure to manage. No worries about scaling under heavy traffic. Just focus on writing code and let the cloud do the rest.
It is possible because of serverless computing.
So, what is serverless computing exactly?
It is a cloud-based model where you build and run applications without managing the basic infrastructure.
Instead of maintaining servers, you just write functions that execute like processing an image upload or handling a user login.
The cloud provider automatically handles everything from scaling to server management.
Tech giants like AWS (with Lambda ), Google Cloud (with Cloud Functions), and Microsoft Azure (with Azure Functions) are investing in serverless platforms.
They are making it easier than ever for businesses to adopt this modern approach.
Whether you are building a startup app or scaling enterprise software, serverless provides better speed, flexibility, and cost-efficiency.
The market size of Serverless computing is expected to reach $54.03 billion by 2030.
That’s why serverless computing is quickly becoming the future of app development.
If you are trying to learn about the best serverless platforms for startups and what is serverless computing then you will get all the answers here.

What is Serverless Computing? (Explained Simply)
Serverless computing doesn’t mean there are no servers. It means you don’t have to manage them.
In traditional development, you need to set up, maintain, and scale servers manually to run your app.
With serverless computing, cloud providers like AWS, Google Cloud, and Azure do all of that for you.
You just write your code, and they take care of everything behind the scenes.
This is where Function as a Service (FaaS) comes in.
Instead of launching an entire application, you launch small, self-contained functions that run only when triggered like when a user clicks a button or submits a form.
These functions scale automatically based on demand, and you only pay for the time your code is running.
So, how serverless computing works is simple:
- You write and deploy your function.
- A user triggers it (like visiting your app).
- The cloud provider runs the function instantly, handles the scaling, and then shuts it down when it’s done.
Serverless computing is perfect for developers who want to move faster, reduce costs, and build modern applications without the usual infrastructure headaches.
Serverless vs Traditional Architecture: What’s the Difference?
When building an application, one of the biggest decisions is choosing the right backend setup.
Should you go with a traditional architecture or use the modern serverless architecture?
The comparison between serverless vs traditional architecture in maintenance, cost, scalability, and speed allows us to see why developers are switching to serverless.
Serverless vs Traditional Architecture
| Feature | Traditional Architecture | Serverless Architecture |
|---|---|---|
| Server Management | You manage and maintain servers manually. | No server management is required as it is handled by the cloud provider. |
| Scalability | Manual scaling based on traffic predictions. | Automatically scales with demand. |
| Cost | Pay for server uptime even when idle. | Pay only for actual usage (when functions run). |
| Deployment Speed | Slower because of infrastructure setup. | Faster & deploy functions directly without full app redeployment. |
| Maintenance | Regular server updates, patches, & monitoring. | Minimal maintenance and focus only on code. |
| Resource Usage | Often overprovisioned (paying for unused resources). | Highly efficient & runs only when triggered. |
| Flexibility | Fixed setup that is harder to change quickly. | More flexible & ideal for agile and event-driven development. |
Serverless architecture allows developers to build and launch applications faster, with lower costs and zero infrastructure headaches.
It is a perfect choice for startups, agile teams, and businesses that want to focus on innovation, not server management.
If you’re still confused about serverless vs traditional architecture, ask yourself: Do I want to maintain servers, or just build a great app?

Is Serverless Right for You? What You Need To Consider?
Serverless computing means no servers to manage, auto-scaling, and pay-as-you-go pricing.
But is it the right fit for your app? Let’s see some of the most important factors to consider before going for serverless computing.
1. App Complexity
- If your app is small with components like APIs, background tasks, & event triggers then serverless computing for microservices architecture is a perfect match.
- For large monolithic applications, migrating to serverless may require breaking down your codebase first.
2. Budget & Cost Efficiency
- Serverless works on a pay-per-use model so you only pay when your code runs.
- This means big savings compared to traditional servers that run 24/7.
- For apps with very high & constant usage costs can increase.
- A detailed serverless computing cost comparison can help you decide if it’s more economical than managing your servers.
3. Performance Requirements
- Serverless platforms are fast but not always instant.
- Some functions can experience a “cold start” delay if they haven’t been used in a while.
- For apps needing ultra-low latency like gaming & trading platforms, this might be a concern.
- For most use cases performance is more than sufficient.
