Serverless computing doesn’t mean you don’t need servers. You just have fewer servers to manage. Let’s look at some of the best runtime platforms to host your serverless applications.

In a traditional application, you manage the entire application logic execution on a VM, physical, or cloud server. However, the trend is changing.

<img alt="serverless computing search term" data- data-src="https://kirelos.com/wp-content/uploads/2023/09/echo/serverless-computing-search-term-1200×581.jpg" data- decoding="async" height="581" src="data:image/svg xml,” width=”1200″>

By going to serverless architecture, you offload the application code execution task to a serverless computing platform. It has many benefits.

  • You don’t need to worry about hosting runtime (Node.js, Python, Go, etc.)
  • Pay what your application consumes (cost-effective)
  • Don’t worry about application grown demand (scalable)
  • Let the provider manage the security, software updates
  • Easy integration with other services offering by the provider
  • Fast time to application deployment and changes

It’s a great deal for a developer and business owner where you focus on your code and expert handle the execution. If you are new to Serverless, then you may refer to this introductory course.

Let’s explore the following FaaS (Functions as a Service) platform.

AWS Lambda

AWS Lambda is one of the first to offer a platform where you run your code and administration is managed (behind the scene) by AWS.

Initially, it supported only Node.js, but today, you can run Python, Go, Java, C#.

<img alt="aws-lambda" data- data-src="https://kirelos.com/wp-content/uploads/2023/09/echo/aws-lambda.png" data- decoding="async" height="233" src="data:image/svg xml,” width=”800″>

As you can see in the illustration, you need to upload your application code, and Lambda will handle the execution. You can either do it manually or automate it by triggering through AWS services or web applications.

AWS Lambda can be helpful in many real-time scenarios like file processing, streaming, data validation, data transformations, handling API requests, etc.

Some of the features:

  • Seamless integration with other AWS products
  • Stateless Lambda functions
  • High-available and fault-tolerant infrastructure
  • Extensive logging and monitoring
  • Automatic scaling
  • and many more.

Good news if you want to play around, AWS offer 1 million requests and 400,000 GB-seconds compute time at no cost under the free tier.

A free tier would be sufficient for a hobby or small project. If you are interested in learning, then you can check this hands-on online course by Stephane Maarek.

And if you are worried about the regulation, AWS Lambda is HIPPA, PCI, ISO, and SOC compliant.

Cloudflare Workers

You heard it right.

Cloudflare is not just a CDN and security company; they offer a lot more than that.

Lately, they have introduced Cloudflare workers, which allow you to run JavaScript at their more than 150 data centers worldwide.

Cloudflare uses the V8 JS engine, so if you need to execute your JavaScript at a faster speed, give it a try.

<img alt="cloudflare-workers-e1552762535324" data- data-src="https://kirelos.com/wp-content/uploads/2023/09/echo/cloudflare-workers-e1552762535324.png" data- decoding="async" height="458" src="data:image/svg xml,” width=”738″>

You can integrate workers with the Serverless framework for faster deployment. You can get it started from as low as $5 per month.

They got a few scripts (recipes) for you to take a look at and play around with to get familiar.

AWS Fargate

AWS Fargate is Amazon’s serverless compute solution to run containers. It offers a pay-as-you-go solution that lets you build serverless platforms. Fargate spares you the burden of managing infrastructure and takes care of scaling, patching, and securing servers.

AWS Fargate is compatible with Amazon ECS (Elastic Container Service) and Amazon (EKS) Elastic Kubernetes Container Service.

The benefits offered by AWS Fargate are:

  • Focused solution to run containers
  • Payment based on CPU resources, memory, and storage used
  • Support for AI and ML development environment
  • Dedicated runtime environment for ECS and EKS tasks to improve security

Azure Functions

Event-Driven computing supports a large number of programming languages.

  • JavaScript
  • C#
  • F#
  • Java
  • Python
  • PHP
  • TypeScript
  • Bash
  • PowerShell

Azure Functions take care of infrastructure demand by your application and scale up or down as and when required. You don’t have to worry about capacity planning.

You can trigger a function from a web application, HTTP API from a mobile application, blob storage, streaming, webhooks, and a lot more.

<img alt="azure-function-web-app" data- data-src="https://kirelos.com/wp-content/uploads/2023/09/echo/azure-function-web-app.png" data- decoding="async" height="284" src="data:image/svg xml,” width=”806″>

Pricing is based on the total time it takes to run your code. There is no upfront cost, and Azure offers 1 million executions for FREE every month.

Go ahead and leverage Azure Functions to build your serverless application for SaaS products, API, etc.

Google Cloud

Google Cloud offers a bunch of serverless computing solutions.

<img alt="google-cloud-serverless" data- data-src="https://kirelos.com/wp-content/uploads/2023/09/echo/google-cloud-serverless.png" data- decoding="async" height="650" src="data:image/svg xml,” width=”722″>

App Engine – a fully managed platform for web and mobile applications. You can deploy your application built in PHP, Python, C#, Node.js, Ruby, Go, etc. You pay for what resources your application consumes and scale based on the demand.

Cloud Functions – an event-driven platform to run Node.js and Python applications in the cloud. You can use Functions to build IoT backends, API processing, chatbots, sentiment analysis, stream processing, and more.

There are more – Storage, Firestore, BigQuery, Dataflow, Pub/Sub, ML engine. Probably, everything you need to build an enterprise-ready serverless application architecture.

IBM Cloud Functions

IBM Cloud Functions is based on Apache OpenWhisk to develop application action that quickly executes on an event trigger.

<img alt="ibm-cloud-functions" data- data-src="https://kirelos.com/wp-content/uploads/2023/09/echo/ibm-cloud-functions.png" data- decoding="async" height="239" src="data:image/svg xml,” width=”769″>

There are some great tutorials on building a serverless platform, API, mobile backend, searchable video, etc., to give you an idea of how it works.

Alibaba Function Compute

An excellent option for China and the International market. Lately, Alibaba announced a serverless computing offering that lets you upload and run code without managing the servers and core infrastructure.

An illustration of real-time IoT message processing serverless flow.

<img alt="alibaba-iot-processing" data- data-src="https://kirelos.com/wp-content/uploads/2023/09/echo/alibaba-iot-processing.png" data- decoding="async" height="597" src="data:image/svg xml,” width=”800″>

Alibaba offers 1 million requests FREE per month. Good for trying out.

The serverless concept is not just FaaS (functions as a service) but a lot more. I hope the above platform helps you build a robust application without worrying about server administration and maintenance. And most importantly, at a lower cost.

StackPath

Conclusion

Going serverless is a great way to save the hosting and infrastructure management cost. Moving legacy applications can be challenging; I get that. But, if you are building a modern new app, you should consider serverless in your architect. Here are some of the valuable resources to learn Serverless.

Good luck!
