Serverless Computing Explained
What Is Serverless Computing?
Serverless computing is a modern cloud computing model where developers can build and run applications without worrying about the underlying infrastructure. Sounds magical, right? But here’s the catch—it’s not actually server-less. Instead, servers are still involved, but all the server management and capacity planning decisions are completely handled by the cloud provider.
Here’s why developers are falling in love with serverless:
No Server Management: Developers can focus solely on writing code. No need to provision or maintain servers.
Scalability: Serverless applications automatically scale up and down depending on the traffic.
Cost Efficiency: You only pay for the actual compute time your code consumes. No charges when the code isn’t running.
Faster Deployments: Serverless enables faster go-to-market since you can deploy functions or microservices independently.
Popular serverless platforms:
Serverless isn’t ideal for every application, but it’s perfect for event-driven tasks like APIs, background jobs, and real-time file or data processing.
Real-World Examples of Serverless Applications
Let’s talk about how businesses are actually using serverless in the real world:
E-commerce Applications: Online retailers use serverless for order processing, inventory updates, and customer notifications. For instance, when a customer places an order, a serverless function updates the inventory and sends an email—all without managing a server.
Media Processing: Platforms like Netflix use serverless to handle video encoding and metadata generation automatically when new content is uploaded.
IoT Data Handling: Serverless platforms can process massive data streams from IoT devices. Smart homes, factories, and wearables often rely on serverless backends to manage real-time data.
Chatbots and Voice Assistants: Serverless functions handle individual user queries, allowing for fast, scalable responses without ever launching a full server.
File Upload Handlers: Whenever a user uploads a file (like images or documents), serverless functions can compress, analyze, or move those files without delay.
As more companies go digital, serverless computing allows them to move faster, scale better, and save money—three things every business loves.
Deploying Serverless Applications
How to Deploy Serverless Applications on AWS
Deploying your first serverless application on AWS is easier than you might think. AWS provides all the tools you need through AWS Lambda and supporting services.
Steps to Deploy:
Write the Code: Start with your function in Python, Node.js, or Java.
Package It: Zip the code and dependencies.

You require complete language or runtime flexibility.
Choosing between the two depends on your application’s architecture, programming language needs, and pricing sensitivity.
Securing Serverless Applications
Common Security Risks
Serverless applications may seem invulnerable because you don’t manage the servers—but don’t be fooled. Security remains your responsibility, especially at the application and configuration level.
Here are some common security risks:
Function Permissions Mismanagement: Granting overly broad permissions can expose data and infrastructure to unauthorized access.
Insecure Third-party Dependencies: Many serverless apps use open-source libraries, which can contain vulnerabilities.
Injection Attacks: Like traditional apps, serverless apps are still susceptible to SQL injections or XSS if not properly sanitized.
Event Data Tampering: Events triggering serverless functions (like HTTP requests or message queues) can be manipulated if not validated.
Denial of Wallet (DoW) Attacks: Unlike traditional DoS, these attacks aim to exploit autoscaling features to rack up a massive bill by triggering functions repeatedly.
Best Practices for Securing Serverless Applications
Securing serverless applications isn’t just about locking down endpoints—it’s about thoughtful design, monitoring, and continual testing.
1. Principle of Least Privilege: Ensure that every function only has the permissions it absolutely needs. Don’t give your Lambda access to everything when it only needs to write to a single S3 bucket.
2. Use API Gateways and Authentication Layers: Control access using API Gateway, OAuth, or token-based authentication (e.g., JWT). Always verify user identities and enforce strong access policies.
3. Monitor and Audit: Use tools like AWS CloudTrail, Azure Monitor, and Google Cloud Audit Logs to track every access and action in your environment.
4. Sanitize Inputs: Always validate and sanitize user inputs. This prevents common exploits like injection attacks or malformed data breaking your logic.
5. Scan Dependencies: Use tools like Snyk or GitHub Dependabot to scan for known vulnerabilities in your dependencies.
6. Apply Rate Limiting: Control how many times a function can be called within a time frame to prevent DoW attacks and abuse.
7. Encrypt Sensitive Data: Use encryption at rest and in transit. Services like AWS KMS, Azure Key Vault, and Google Secret Manager can help manage your secrets.
8. Keep Your Functions Small and Isolated: Smaller, single-purpose functions are easier to test, debug, and secure. They reduce the blast radius in case something goes wrong.
By embedding security into your development pipeline and following these practices, you ensure your serverless applications are both efficient and safe.
Cost Comparison of Serverless Computing
AWS vs. Azure vs. Google Cloud Pricing
When you go serverless, one of the biggest selling points is cost. But each cloud platform handles pricing a bit differently. Let’s compare:

| Compute Pricing | Based on GB-seconds & invocations | Similar model to AWS | Per GB-s & CPU-s |
| Duration Granularity | 1 ms | 1 ms | 100 ms |
| Max Execution Time | 15 minutes | 60 minutes | 9 minutes |
| Idle Time Charges | No | No | No |
What Makes Serverless Cost-Efficient?
No Idle Charges: You’re billed only when your function runs. No need to pay for “uptime.”
Auto-scaling: Scale without increasing infrastructure costs.
Granular Billing: Only pay for the exact compute resources used.
Factors Affecting Serverless Costs
Despite the attractive pricing model, costs can sneak up on you if you’re not careful.
1. Cold Starts: Longer cold start times can slow down performance, possibly leading to higher execution time and costs.
2. Function Duration: The longer your function runs, the more you’ll pay—so optimizing code is crucial.
3. Data Transfer: Functions that process large datasets or stream video/audio can incur bandwidth charges.
4. Third-Party APIs and Services: Integrating with paid APIs or external services may add hidden costs.
5. Logging and Monitoring: Logging via CloudWatch, Stackdriver, or Azure Monitor can rack up additional charges if not managed properly.
Pro Tip:
Use pricing calculators offered by AWS, Azure, and GCP to estimate your costs ahead of deployment.
In short, serverless can be extremely cost-effective, but keeping an eye on the variables ensures you stay within budget.
