Then came Platform as a Service (PaaS), which enabled developers to focus on coding without worrying about the underlying infrastructure. Serverless is considered the next step in this evolution. Serverless architecture, particularly Function as a Service (FaaS), emerged around 2014 with the launch of AWS Lambda. Since then, serverless has been on the rise, and according to DataDog, the adoption of AWS Lambda grew by 375% between 2018 and 2020. The rise of serverless can be attributed to its ease of use, cost-effectiveness, and scalability.
Overview of the benefits and challenges Serverless architecture comes with several benefits. First and foremost, it’s cost-effective as you only pay for the computation time you consume. According to a report by Deloitte, this can reduce operational costs by up to 60%. It also offers automatic scaling, which means your application can handle any amount of traffic. Additionally, serverless enables faster development and deployment cycles.
However, there are also challenges associated with serverless. Vendor lock-in is a common concern because your application’s architecture might be tied to the capabilities of a specific cloud provider. Debugging and monitoring are also more complex in a serverless environment. According to IOpipe, 37% of AWS Lambda users spend more than one day per week resolving issues in production. Additionally, cold starts can cause latency issues, which might not be suitable for real-time applications.
In the subsequent chapters, we will delve deeper into serverless architecture, discussing its components, real-world examples, and how to integrate it into your company. Whether you are a developer, manager, or business owner, this guide will equip you with the knowledge and insights you need to make informed decisions about serverless technology.
What is serverless computing? Serverless computing is a cloud-based execution model that automatically manages the server resources needed to run applications. Instead of provisioning, scaling, and maintaining servers, developers can focus on writing code, and the cloud provider takes care of the rest. In serverless computing, applications are broken down into functions, and these functions execute in response to events such as HTTP requests or database modifications. According to a CNCF Survey, serverless adoption grew from 40% in 2019 to 45% in 2020, signaling a growing shift towards this computing model.
Difference between traditional servers and serverless In traditional server-based architectures, you have either physical servers or virtual machines that need to be managed and maintained. This includes taking care of server patching, scaling, and capacity planning. On the contrary, serverless abstracts all these aspects. It allows developers to run code without managing the servers. Serverless scales automatically, and you are billed based on the actual amount of resources consumed by your application. According to a report by LogicMonitor, 41% of enterprise workloads will be run on public cloud platforms like AWS, Azure, and Google Cloud by 2021, as part of this shift from traditional servers to serverless and other cloud-native architectures.
Components of serverless architecture Serverless architecture typically consists of two main components: Function-as-a-Service (FaaS) and Backend-as-a-Service (BaaS).
Function-as-a-Service (FaaS) FaaS is a category of cloud computing services that provides a platform allowing customers to develop, run, and manage application functionalities without the complexity of building and maintaining the infrastructure. In FaaS, the unit of deployment is a single function. These functions are stateless, and they can scale horizontally - meaning if there are more requests, more function instances can be run parallelly.
Backend-as-a-Service (BaaS) BaaS allows developers to outsource all the behind-the-scenes aspects of a web or mobile application so that they only have to write and maintain the frontend. This means that the backend is completely managed by a third party. BaaS is particularly useful for applications with predictable patterns and can significantly reduce the amount of boilerplate code that developers have to write.
Key providers in the serverless market (AWS Lambda, Azure Functions, Google Cloud Functions) There are several key providers in the serverless market, with AWS Lambda, Azure Functions, and Google Cloud Functions being the most prominent.
