Top 10 Serverless Frameworks for Deploying Serverless Applications

Let’s say you are building a serverless application with AWS (Amazon Web Services) Lambda. Now, if you want to automate function deployment, you will most likely do so via CI/CD (continuous integration and continuous deployment) workflow.

But integrating Lambda into a DevOps pipeline requires additional underlying plumbing. For instance, managing multiple configurations of the functions and related resources (such as API Gateway, IAM policies, CloudWatch log groups, AWS Lambda Debugging).

Plus, there are added challenges such as interfacing with multiple programming languages or dealing with a large number of microservices. Hence, despite its countless benefits, serverless comes with a catch.

It is where serverless deployment frameworks step in. They are tools to enable developers to deploy serverless infrastructure quickly and seamlessly. While AWS offers first-party tools, various third-party frameworks are available in the market for deploying serverless applications.

This blog post talks about some popular serverless frameworks used today for deploying applications with FaaS (Function as a Service) and their use cases.

Simform is a leading serverless app development company helping organizations develop robust applications with an efficient infrastructure. Talk to our experts today to help you pick the right tools for your serverless project!

1.Serverless Framework

serverless frameworkInitially developed to build applications on AWS Lambda, Serverless is now the most popular serverless framework. It helps you quickly develop, deploy, and manage serverless applications with Lambda and other FaaS platforms. It supports Azure Functions, Google Cloud Functions, Apache OpenWhisk, Kubeless, and more.

Serverless Framework automatically creates the infrastructure needed for your configured functions and events. So you can build sophisticated, event-driven apps or microservices that will auto-scale based on demand. It is also provider-agnostic, allowing you to package and deploy applications across multiple clouds, for example, Google Cloud, Azure, AWS, etc.

Moreover, you can extend its use cases by modifying the framework’s behavior via plugins. Serverless has a large ecosystem of plugins for building use cases currently not supported.

Serverless Framework is used by top companies such as Coca-Cola, Reuters, Nordstrom, Expedia, and more. For example, GoDaddy used it to manage serverless deployments– to configure and deploy AWS services, test code locally, and easily package and deploy code changes.

Unique features:

  • Free and open-source, supported by a large community
  • Simple, abstract syntax in YAML
  • Supports multiple languages such as Node.js, Python, Java, Go, C#, Scala, Kotlin, Swift, PHP, and more
  • CLI (command-line interface) for structure, automation, and out-of-the-box practices
  • Dashboard for a centralized view of infrastructure, performance, logs, errors, etc
  • Numerous useful built-in commands and monitoring tools
  • Allows Infrastructure as Code (IaC)
  • Extensible via plugins

Use cases of Serverless Framework

  • Event streaming pipelines
  • Image and video manipulation
  • IoT applications

how sam works SAM’s shorthand syntax allows developers to define resources in just a few lines, which may take a hundred lines in AWS CloudFormation. You can build various applications with AWS SAM, including robust event-driven asynchronous tasks. Moreover, it supports image-based Lambda functions using Docker, further simplifying serverless development.

Unique features:

  • Single deployment configuration, as all related resources are versioned together as a single entity
  • Seamless integration with CI/CD pipelines
  • SAM CLI that provides a Lambda-like execution environment facilitating local building, testing, and debugging of applications defined by SAM templates or AWS CDK
  • SAM Accelerate for cloud based development, that enables developers to test code changes in the cloud and bypass local emulation for serverless applications
  • Integrates with a suite of other AWS serverless tools
  • Has numerous useful in-built SAM CLI commands (such as sam init, sam logs, and sam package, among popular ones)
  • Inherent AWS security best practices
  • Integrates with CDK
  • Access to a list of policy templates to scope permissions for Lambda functions

Use cases of AWS SAM

The framework is widely used to automate the deployment of serverless applications based on AWS Lambda, API Gateway, DynamoDB tables, and S3 services. Below are a few scenarios where AWS SAM would be a good fit:

  • For deploying multiple Lambda as a part of a larger application
  • If you want to use CloudFormation as IaC tools
  • If there is no creation of resources outside of AWS

3.Terraform

terraform serverless frameworkPopularly known as an IaC service, Terraform is an automation scripting tool similar to AWS CloudFormation. It is used to create, deploy, and manage cloud infrastructure across multiple cloud providers and services.

Terraform integrates with major cloud vendors, including AWS, Azure, Google Cloud Platform (GCP), Alibaba Cloud, Oracle Cloud, Kubernetes, etc. So, you can deploy and manage multi-cloud, large-scale infrastructures. It also allows you to scale and monitor multi-tier app architectures seamlessly.

Moreover, Terraform lets you spin up parallel environments rapidly for development, QA, testing, and production. Thus, as the environments grow more complex, creating disposable ones can prove more cost-efficient than maintaining them indefinitely. And you can also deploy and manage Kubernetes clusters with Terraform.

It is a popular tool among companies such as Slack, Robinhood, Udemy, Medium.com, Decathlon, and more. For instance, Uber uses a mix of Terraform and other internal tools to manage its hybrid cloud infrastructure made of multiple cloud providers and active data centers.
