Google’s bright minds never disappoint you with the innovative and forward-thinking. Everybody saw that serverless is going to play an integral part in the upcoming years. To be prepared and serve the products to meet the demands of the customers, Google released Cloud Functions in 2016 and made it generally available at Google Cloud Next’ 18 in San Francisco.
So, what is Google Cloud Function?
Google Cloud Function in the simplest words is a Function-as-a-Service (FaaS). FaaS is actually a family of the serverless computing category. Does this mean that your code runs without servers? Well, that can’t be possible, serverless computing still requires servers. What it actually means is that a developer can write and deploy code eliminating the need for managing the infrastructure.
“Serverless” means that the user can focus on its application logic without dealing with infrastructure at all. Painless development, deployment, and maintenance of a web API is still not a turn-key solution, although modern web application frameworks have improved dramatically in the last few years. Serverless is without any doubt a game-changer. The event-driven approach combined with a scalable and robust cloud ecosystem offered by the main top cloud vendors opens endless opportunities.
Cloud Functions is Google Cloud’s event-driven serverless compute platform. FaaS is a real NoOps technology, it completely abstracts away servers. Cloud Functions are developed with the sole purpose to build event-driven architectures. These can react to events like file changes in storage, messages in the queue, or any HTTP request.
Benefits of Cloud Functions
No server management
One thing that you might have comprehended about Google Cloud Functions is that there no hassle of server management. Users can simply create a code and Google will run it for you and scale it when needed. Google Cloud helps to isolate the infrastructure enabling you to focus just on code and building applications quicker.
Google Cloud Functions are short-term and are spun up on demand in response to events. So, you basically have to pay only for the time that the function is running. You don’t need to think about the infrastructure provisioning as Cloud functions automatically scale up or down depending on the workload size.
Any change in data leads to a change in how to code will be executed. Hence, the cloud functions respond to a variety of events from cloud services such as cloud storage and many more. The execution of code with respect to data changes is helpful in the data processing. Such as generating a thumbnail after an image is uploaded to a storage bucket or processing of incoming logs.
The integration of various cloud applications is another key advantage that benefits the cloud function users. Cloud Functions allows user to leverage different platforms such as GCP, Firebase, etc. as the building blocks and integrate these using codes. The integrations help developers to rapidly move from ideation to production stage.

Cloud Functions’ Competitors
Google launched Cloud Functions in 2016 but Amazon launched its similar (or users might say matured service) service in 2014, i.e., AWS Lambda Functions. This is not the only competitor for Cloud Functions, in fact, Azure Functions is competing in a similar domain of FaaS (Function-as-a-Service). But out of three, AWS Lambda functions is already a mature product when it comes to capabilities.
