What is FaaS? If you and your team ask this question, you’re probably looking into cloud computing services. More specifically, you are most likely researching the different cloud delivery models

Function as a Service (FaaS) is one of the various cloud models. Other models are IaaS, PaaS, and SaaS. FaaS is almost exclusively focused on the development of microservices. If your app is highly dependent on cloud computing, it can benefit from using this microservices model.

Thanks to its simplification of the processes associated with the maintenance and building of infrastructure, the FaaS model can significantly impact your app and your business. Ultimately, it will allow you to build what is commonly referred to as serverless architecture or serverless computing.

In this post, we discuss the HiTech FaaS model and how it can benefit your application development project. By implementing it, you will improve how your app manages resource allocation. Depending on your project’s business logic, this can have substantial benefits for your company.

What Is FaaS?

Depending on the level of service of an app you are working on, you can use the different alternatives that a cloud provider has to offer to address your application’s specific needs. Function as a Service, also known as FaaS, is a cloud computing service offered by a Cloud Service Provider (CSP). 

The Function as a Service model is often referred to as an advanced cloud computing model that can be used specifically to build a serverless architecture and manage microservices.

Managing an app through a FaaS model can be beneficial, especially if your app is service-oriented and relies heavily on microservices. This can be a significant change from the previous workflows of many companies. 

The FaaS model allows companies to execute their code in the cloud while the service provider manages the entire back-end operation. This helps server processes become more efficient, helping them scale when needed. Ultimately, this will save you a lot of resources and, most importantly, headaches.

Use Cases

Depending on your project’s business logic and technical requirements, the FaaS model may be more or less beneficial. In short, it is great at allocating your app’s resources through dynamic scaling when managing servers and scheduled tasks.

In particular, the Function as a Service model can be used in app development projects that involve intermittent processing requests. Because of this, it is great for intermittent interactions, such as those of IoT apps and devices. By using it, IoT apps and devices can optimize their server resource consumption.

Lastly, it is important to remember that apps that use this service perform very well for data processing, validation, and sorting. So, if you have to manage a high number of requests, this might be a good fit for you.

Common Pricing Characteristics

Normally, this model requires customers to pay only for the cloud computing services they use. In practical terms, this means that you only have to pay for the actual runtime used to execute a specific function. When using Function as a Service, you won’t be charged for idle time between executing one function and the next one.

Take into consideration your app’s intended use cases and these pricing characteristics. The FaaS model might be ideal for your app, depending on its business logic and how you are managing servers and other technical aspects. 

If you are unclear on whether this is what you need, you might want to consider a product discovery workshop.

Serverless Architecture for Your Application

This, also known as serverless computing, is one of the most important characteristics to consider when using Function as a Service. Like other delivery models, it will allow you to run your cloud services without having to manage the supporting infrastructure and other critical components.

This sounds like something minor, but depending on the size of your team, the number of users of your app, and the growth of your business, managing servers can quickly become a pain point. If not taken care of adequately, it can even break your app.

Whether you are working on web development or mobile development, guaranteeing dynamic scaling for your app is crucial. That is why many companies see serverless computing as a convenient solution.

Automating the server process is key for any project that involves cloud computing, independently of whether you are using AWS, Google Cloud, or Azure functions. To make the most of cloud computing automation, make sure to understand cloud app development.

Final Thoughts on Function as a Service (FaaS)

In the end, the benefits of cloud services sum up to optimized resources, reducing costs, and a seamless operation of your app. As a cloud technology, the Function as a Service model is no exception. It contributes to your app in many different ways.

If you are looking to integrate this service into your app project, make sure to work with someone who understands this technology. Using it correctly is not only about the technical expertise needed to implement it. It also requires understanding your business logic to ensure that every minor detail is taken care of.

An app development company with experience in cloud technologies can be your best partner in this endeavor. That way, you won’t have to waste your time understanding what is FaaS and instead just implement it.
