8 Serverless Computing Platform to Run Your Application Code

Some of the simplest runtime platforms to host your serverless applications.

Serverless architecture doesn’t mean you don’t need servers. Instead, you would like fewer servers to manage. during a traditional application, you manage the whole application logic execution on a VM, physical, or cloud server. However, the trend is changing. By going serverless architecture, you offload the appliance code execution task to a serverless computing platform. It got many benefits.

You don’t get 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 safety, software updates

Easy integration with other services offering by the provider

Fast time to application deployment and changes

It's an excellent deal for a developer and business owner where you specialize in your code and expertly handle the execution. If you're new to Serverless, then you'll ask for this introductory course.

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

AWS Lambda

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

Initially, it had been supporting only Node.js, but today, you'll run Python, Go, Java, C#. As you'll see in the illustration, you would like to upload your application code, and Lambda will look out for the execution. you'll either roll in the hay manually or automate it by triggering through AWS services or web applications.

AWS Lambda is often 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 would like to fiddle, AWS offer 1 million requests and 400,000 GB-seconds compute time at no cost under the free tier.

Free tier would be sufficient for hobby or small project. If you're curious about learning, then you'll check this hands-on online course by Stephane Maarek.

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

Cloudflare Workers

You heard it right.

Cloudflare isn't just a CDN and security company; they provide tons quite that.

Lately, they need to introduce Cloudflare workers which permit you to run JavaScript at their quite 150 data centers around the world.

Cloudflare uses the V8 JS engine, so if you would like to execute your JavaScript at a faster speed then provides an attempt to workers.

You can integrate workers with the Serverless framework for faster deployment. you'll catch on started from as low as $5 per month.

They got a couple of scripts (recipes) for you to require a glance and fiddle to urge conversant in.

Now

I like the name – Now.

Now by Zeit is ideal for developers. You build and push the code and the rest is managed by Now. Don’t worry about hosting optimization or managing the configuration. It supports Node.js, PHP, Go, React, and lots more. the good time-saving advantage is it re-builds only the changes rather than the entire application repository. Once you push the code changes, deployment is visible in seconds. you'll catch on started in FREE and scale as your application grows.

Azure Functions

Event-Driven computing supports an outsized number of programming languages.

JavaScript

C#

F#

Java

Python

PHP

TypeScript

Bash

PowerShell

Azure Functions lookout for infrastructure demand by your application and proportion or down as and when required. You don’t need to worry about capacity planning.

You can trigger a function from an internet application, HTTP API from a mobile application, blob storage, streaming, webhooks, and tons more. Pricing is predicated on the entire time it takes to run your code. there's no upfront cost, and Azure offer 1 million executions FREE monthly.

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

Google Cloud

Google Cloud offers a bunch of serverless computing solutions app Engine – a totally managed platform for web and mobile applications. you'll deploy your application inbuilt PHP, Python, C#, Node.js, Ruby, Go, etc. You buy what resources your application consumes and scale supported the demand.

Cloud Functions – an event-driven platform to run Node.js and Python applications within the cloud. you'll use Functions to create 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 would like to create an enterprise-ready serverless application architecture.

IBM Cloud Functions

IBM Cloud Functions is predicated on Apache OpenWhisk to develop application action which executes on an occasion trigger quickly there are some great tutorials on building a serverless application, API, mobile backend, searchable video, etc. to offer you a thought of how it works.

Alibaba Function Compute

An excellent option for China and therefore the International market. Lately, Alibaba announced a serverless compute offering which allows you to upload and run code without managing the servers and core infrastructure.

An illustration of real-time IoT message processing serverless flow. Alibaba offers 1 million requests FREE per month. Good for trying out.

The serverless concept isn't just FaaS (functions as a service) buttons more. I hope the above platform helps you to create a strong application without fear about server administration and maintenance. And most significantly, at a lower cost.

EdgeEngine

EdgeEngine by StackPath deploy serverless functions written in JS, Perl, Rust, Go, C++, PHP, etc. almost your audience’s network edge for faster reaction time. The latency of EdgeEngine is as low as 50ms. Pricing starts from $10 per month which incorporates 15 million requests and unlimited scripts. And, doubtless, you'll proportion.

Executing functions at the sting network got many advantages like user’s personalization content, application performance improvement, quicker deployment, etc.

Conclusion

Going serverless may be a good way to save lots of the hosting and infrastructure management costs. Moving legacy application are often challenging; I buy that. But, if you're building a contemporary new app, you ought to consider serverless in your architect. Here are a number of useful resources to find out about Serverless.
