In recent years, mentoring at various coding bootcamps, I've had the unique opportunity to guide and support numerous junior developers passionate about making their mark in cloud engineering & DevOps. A recurring theme I've noticed among these aspiring engineers is their eagerness to dive into the complexities of cloud computing but often feeling overwhelmed by the vast array of programming languages and tools available. This realization sparked a thought in me to create a comprehensive yet approachable guide that shines a light on the essential programming languages for anyone starting their journey in cloud engineering.

On the similar lines, here are seven programming languages every cloud engineer should know in 2024, each selected for its relevance, capabilities, and role in enabling modern cloud solutions.

## 1. Wing

![wing lang](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/6syu6oqhs93z0sq77cvf.png)

[Wing](https://github.com/winglang/wing)'s design philosophy emphasizes productivity, security, and efficiency, enabling developers to stay within a single, intuitive workflow throughout the development process. 

By treating infrastructure resources as first-class citizens, Wing allows developers to define, interact with, and manage these resources directly within their application code. This integration significantly reduces the complexity and potential for errors associated with managing cloud infrastructure, making it easier to build and deploy secure, scalable applications.

One of the key features of Wing is its ability to compile into both Infrastructure as Code (IaC) formats, such as Terraform, and JavaScript. 

Wing's support for local simulation of cloud applications is a game-changer for developer productivity. Being able to run, visualize, interact with, and debug cloud applications in a local environment before deployment can significantly speed up the development cycle and improve application quality. This capability, combined with the language's design for easy integration with DevOps practices, ensures that developers can apply continuous integration and continuous deployment (CI/CD) methodologies more effectively, aligning with modern software development practices.

Take a look at [Wing’s interactive playground](https://www.winglang.io/play/) to understand how the Wing language works. 
Working with Wing is easy and super simple. 

You can install Wing in seconds and start automating your cloud workflows.

```
npm install -g winglang
```

You can verify your installation using the command below.

```
wing -V
```
Use the CLI to bootstrap a new project: Use the new command and then modify main.w to have the following:

```
wing new empty
```

```
bring cloud;

// define a queue, a bucket and a counter
let bucket = new cloud.Bucket();
let counter = new cloud.Counter(initial: 1);
let queue = new cloud.Queue();

// When a message is received in the queue it should be consumed
// by the following closure
queue.setConsumer(inflight (message: str) => {
  // Increment the distributed counter, the index variable will 
  // store the value prior to the increment
  let index = counter.inc();
  // Once two messages are pushed to the queue, e.g. "Wing" and "Queue".
  // Two files will be created:
  // - wing-1.txt with "Hello Wing"
  // - wing-2.txt with "Hello Queue"
  bucket.put("wing-{index}.txt", "Hello, welcome to winglang world!");
  log("file wing-{index}.txt created");
});
```
Use the wing it command to start the console with our newly created application:

```
wing it main.w
```

The Wing Console, gives you a view of your cloud application, enabling developers with faster iterations and hot reloading:

## 2. Python

![python lang](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/r7gdgxhcb4mjywdih30u.png)

[Python](https://github.com/python) remains an indispensable language for cloud engineers due to its simplicity, versatility, and robust ecosystem. Its extensive collection of libraries and frameworks, such as Flask for web applications and TensorFlow for machine learning, makes Python a go-to language for developing a wide range of cloud-based services. Furthermore, Python's role in automation, scripting, and data analysis ensures that it continues to be a critical tool for cloud infrastructure management, automation tasks, and the rapid prototyping of cloud applications.

## 3. Go (Golang)

![golang](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/p5ggz0p6ix46uqifhmd7.png)
[Go](https://github.com/golang/go), or Golang, designed by Google, has become increasingly popular among cloud engineers for building high-performance and scalable cloud services. Its efficiency, simplicity, and built-in support for concurrency make it an excellent choice for developing microservices, distributed systems, and containerized applications. Go's compatibility with cloud platforms and its ability to handle heavy network traffic and complex processing tasks efficiently contribute to its growing adoption in cloud infrastructure projects.

## 4. JavaScript (with Node.js)

![nodejs lang](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/s5q16t3w3zf8xctgrlvg.png)
[JavaScript](https://en.wikipedia.org/wiki/JavaScript), particularly when used with Node.js, is essential for cloud engineers focused on building and deploying scalable and efficient web applications. Node.js allows JavaScript to be used on the server side, enabling the development of fast, non-blocking, event-driven applications suitable for the cloud. JavaScript's ubiquity across client-side and server-side development also facilitates full-stack development capabilities, making it invaluable for engineers working on cloud-based web services and applications.

## 5. Rust

![Rust lang](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/c3f1w421ksertrrldyod.png)
[Rust](https://www.rust-lang.org/) is gaining momentum in the cloud computing domain due to its emphasis on safety, speed, and concurrency without a garbage collector. These features make Rust an appealing choice for cloud engineers looking to develop high-performance, secure, and reliable cloud services and infrastructure. Rust's memory safety guarantees and efficient compilation to machine code position it as an ideal language for system-level and embedded applications in cloud environments, where performance and security are paramount.

## 6. Kubernetes YAML

![kubernetes yaml](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/mga2ylbbc9g98w4hjkmg.png)
While not a programming language in the traditional sense, [Kubernetes YAML](https://kubernetes.io/docs/concepts/overview/working-with-objects/) (YAML Ain't Markup Language) is essential for cloud engineers working with Kubernetes, the de facto standard for container orchestration. Mastery of Kubernetes YAML is crucial for defining, deploying, and managing containerized applications across cloud environments. Understanding the intricacies of Kubernetes resource files and configurations allows engineers to leverage the full capabilities of container orchestration, ensuring scalable, resilient, and efficient cloud-native applications.

## 7. Terraform HCL (HashiCorp Configuration Language)

![Terraform hcl](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/ke9hjhkw6k2i9zald105.png)
[Terraform HCL](https://github.com/hashicorp/hcl) (HashiCorp Configuration Language) is an essential language for cloud engineers in 2024, particularly for those involved in infrastructure as code (IaC) practices. HCL is the configuration language used by Terraform, a widely adopted tool that enables engineers to define, provision, and manage cloud infrastructure using a declarative configuration approach. Learning Terraform HCL allows cloud engineers to automate the deployment and lifecycle management of cloud resources across various service providers, ensuring consistency, repeatability, and scalability of cloud environments.

### Wrapping Up
In 2024, all languages have their strengths, and I’ve enjoyed putting my thoughts together regarding Cloud Engineering and DevOps. 

If I could offer my students' advice, amidst the rapid expansion of this growing field, mastering Wing emerges as a compelling choice. 

[Wing](https://www.winglang.io/) provides cloud engineers and developers with a distinctive advantage, offering local testing with the console, hot reloading (a challenge for most Cloud Engineers), and enhanced scalability, not to mention security for cloud applications.
