The frameworks for serverless architecture provide us with an abstraction layer on AWS services in general and on AWS lambda in particular.
The adoption of Software Architecture based on microservices has many advantages, it allows us to change from a monolithic software construction to our own more distributed and agile one. AWS provides us with different services which help us to host our lambda functions and connect them with the other parts that make up our systems.
You can create the lambda functions from the graphical interface provided by the AWS console. This method is simple, however we lose the possibility of using the development environment of our computer which has our specific configurations, IDEs and also our version control systems.
To address this, AWS allows us to build our infrastructure through code. This service is known as CloudFormation.
CloudFormation
With CloudFormation we can create the infrastructure and configurations of a large number of AWS services, including lambda functions. It also allows us to share configurations with other members of the development team. Creating a function and accessing it through an API requires writing a considerable amount of configuration.
As the number of functions in our project grows, these configurations can reach hundreds of lines.
It is for this reason that it is recommended to use a framework that helps us to generate the necessary infrastructure, permissions and configurations so that our functions can operate. The frameworks that work with lambda functions also allow us to simulate the environment in which they operate to be able to execute them locally for debugging and testing tasks. The time has come to use frameworks for serverless architecture in your company!
Frameworks for serverless architecture
Among the frameworks for serverless architecture, we can find that it has the Amazon service called AWS SAM (Serverless Application Model). This Open Source tool is installed in the terminal. AWS SAM operates through a "template" of configurations as can be done with CloudFormation but in a simplified version.
There are various commands that you can consult in its official documentation with which you can verify that the template is written correctly and also test the functions that make up our architecture based on microservices. It also simplifies the process of uploading our code to AWS with commands to deploy without leaving the terminal.
Another tool for handling lambda functions from our terminal is Serverless Framework. This tool is installed as a global NodeJS package, although it is compatible with functions written in Python and other programming languages that support lambda functions.
Like AWS SAM, it is necessary to add a configuration template in which we define the function names, entry points, amount of RAM and other specifications. Serverless Framework also has compatibility with other cloud services besides AWS.
Frameworks for serverless architecture streamline development work and allow developers to focus more on the code rather than spending time deploying code and dealing with configurations.
In Codster We have extensive experience in its use, which allows us to develop new projects based on microservices and migrate traditional monolithic systems to serverless architecture in record time.
