Introduction

In today's fast-paced tech industry, small teams often need to quickly build and Scale backend applications with complex requirements. However, building a robust back-end system in the cloud is not a simple task. It requires a deep understanding of infrastructure engineering and the ability to handle issues like latency, throughput, reliability, and scalability. These challenges often lead to underestimating the complexity that microservices introduce, resulting in significant slowdowns for development teams.

To address this problem, Clodo, a new open-source tool, has been developed. Clodo allows developers to transform plain applications into cloud-native ones using a few declarative and contextual annotations. These annotations empower your code with cloud capabilities and automatically generate Pulumi code for the necessary components and resources needed to power your application in a cloud setting. Clodo makes it easy to build scalable and reliable back-end systems without requiring deep expertise in infrastructure engineering.

Understanding the Complexity of Building Back-end Systems

Building a back-end system for a modern application involves much more than writing code. A real-life application often requires databases, caches, multiple application services, and non-trivial topologies. Additionally, performance, security, and auditing are important considerations. Research and surveys have shown that underestimating the complexity of microservices introduces a significant challenge for developers and cloud engineers.

The Need for Cloud Services in Building Products

Small teams that focus on building products need to leverage the public cloud for their back-end infrastructure. Cloud service providers like AWS, Google Cloud Platform (GCP), and Azure offer a wide range of services that simplify the deployment and management of cloud resources. However, utilizing cloud services effectively requires expertise in infrastructure as code (IaC) tools.

Introducing Clodo: A Tool for Transforming Plain Applications into Cloud-Native Ones

Clodo is an open-source tool designed to simplify the process of transforming plain applications into cloud-native ones. It enables developers to leverage the power of cloud services without the need for deep expertise in infrastructure engineering. By adding a few declarative and contextual annotations to your code, Clodo can automatically generate Pulumi code for the necessary cloud resources.

What is Infrastructure as Code?

Infrastructure as code (IaC) tools allow developers and cloud engineers to describe infrastructure using code or templates. With IaC, You can define resources like Lambdas, Kubernetes clusters, IM policies, and gateways, along with their interconnections. However, traditional IaC tools require external configuration of application code, which can lead to challenges in maintaining alignment with the infrastructure.

How Pulumi and Clodo Help Developers

Pulumi is an infrastructure as code platform that simplifies the deployment and management of cloud resources. It provides features like stack management, deployment processes, and configuration storage. Clodo enhances the capabilities of Pulumi by leveraging its understanding of architectures to automatically generate and maintain infrastructure code. It allows developers to focus on building features and capabilities, while Clodo handles the complexity of translating application constructs into cloud constructs.

Demo: Transforming a Local App into a Cloud-Native Architecture

To better understand how Clodo works, let's walk through a demo. We will start with a plain TypeScript application that extracts text from images using OCR (optical character recognition). The application runs locally and returns the extracted text as a JSON payload.

Using Clodo's annotation system, we can annotate parts of the code to transform it into a cloud-native version. By adding annotations to the app.listen function, we can expose it as a public API endpoint using API Gateway and AWS Lambda. Clodo automatically generates Pulumi code to deploy this architecture on AWS.

Enhancing Functionality: Making Data Persistent and Handling Asynchronous Operations

To make our application more robust, we can use Clodo's annotations to persist data and handle asynchronous operations. By adding the persist annotation to an ES6 map, Clodo transforms it into a DynamoDB table. This ensures that data remains intact even in the event of process failures or cold starts.

We can also use Clodo to decouple specific functionality and make our app more scalable. By utilizing the exec annotation, we can transform certain routers into separate Lambdas or remote procedure calls (RPCs). This allows independent execution and better management of resources.

Expanding the App: Adding Event-driven Architecture and Long-Running Processes

Clodo goes beyond simplifying the deployment and management of cloud resources. It empowers developers to build event-driven architectures by annotating code with emitters and event handlers. Clodo's Pub/Sub capability makes it easy to connect Lambda functions and handle asynchronous communication between them.

In the final example, we illustrate how Clodo makes it easy to modify the architecture by switching from Lambdas to Kubernetes pods running on Amazon EKS. By modifying the Clodo configuration file, we can change the execution units and deploy our app as long-running processes. This ensures faster execution and eliminates cold starts.

Conclusion

Clodo is a powerful tool that enables developers to transform plain applications into cloud-native ones. It simplifies the complex process of building robust back-end systems and empowers teams to focus on building features and capabilities. By leveraging Clodo's annotations and Pulumi's infrastructure-as-code capabilities, developers can easily integrate cloud services and scale their applications.

With Clodo, you can bridge the gap between application code and infrastructure code, making your application truly scalable, reliable, and flexible. Try Clodo today and experience a generational leap in productivity for your backend development projects.
