Building serverless apps or setting up a serverless architecture has been a pretty hot topic in recent years.
But seeing if this is the right fit for your application is not that clear.
So in this post, we compressed every information you need to know about serverless applications, collecting the pros and cons to make your architectural decision much easier.
We kinda live and breathe serverless architecture, so if you have any questions, we’re happy to help.
Honestly, the word “serverless” is quite misleading.
Even though the technology is called serverless, your application isn’t running on thin air.
In case of serverless architecture, you don’t have to worry about setting up and managing the server infrastructure. You don’t have to have your own physical server since your architecture runs in the cloud.
You don’t have to worry about maintenance, scaling and the processes of the server since everything is taken care of by a service provider such as AWS.
When you have a serverless architecture, you only pay for the resources your application/function consumes, and you have infinite scaling on your functions or app.
To achieve the insane scaling, each function of your app runs in a different container. They might be on different machines too!
Their lifecycle is super short. Once a triggering event happens, a container with your function is initialized, your code is executed, and after some time, the container is gone. We cannot use the underlying server to store the application state, file or anything else.
With serverless architecture, you don’t need the traditional always-on server infrastructure. Serverless architectures are event-triggered, working only when there is activity in your app.
There are also powerful frameworks you can use to develop and deploy serverless applications. More on this below.
Why should you consider a serverless architecture? Here are some advantages you can expect.
· Easy integration with other cloud services
Besides the upsides, serverless architecture bears some disadvantages too.
There are two main serverless frameworks we use to easily deploy serverless apps.
Madbro is a serverless advertising platform where users can pay for gated content by watching targeted video ads.
It also provides an alternative and more efficient business model for online publishers, increasing revenue without distracting the audience with unsolicited advertisements. Since the application has to deal with a volatile load, using serverless backend was a hands-on solution to handle load spikes.
Madbro is a web application that can be integrated with any website, and it’s also compatible with every platform (such as iOS, Android, and Windows).
It applies an online micropayment technology letting users pay by watching videos.
The application has a full serverless backend except for MongoDB built with AWS CloudFront, AWS API Gateway, AWS Cognito, Amazon Simple Storage Service (S3), AWS Lambda, AWS Elastic Transcoder. Backend has built-in error tracking using Sentry and Cloud Watch.
What are these services doing?
Serverless architecture definitely helps solve some burning architectural issues such as scaling and making your infrastructure cost-effective. Apart from the many great features it offers, there are some disadvantages that need to be carefully considered. You can use our serverless grader to give a rough estimate if your app’s characteristic matches with the serverless requirements. If you’re considering building an app on serverless architecture, you need to know that a bunch of serverless experts are ready to take your project to the next level.
