Application of C++ and Python in cloud computing

C and Python have their own advantages in cloud computing: C is known for its high performance and low-level control, and is widely used in high-performance computing, server-side applications and game development; Python is known for its ease of use, rich libraries and extensive Known for community support, it is often used in data science, machine learning, web development, and script automation.

Application of C and Python in Cloud Computing

Cloud computing is popular for its scalability, low cost and agility. Become an essential tool for modern businesses. C and Python, two popular programming languages, play a vital role in the field of cloud computing. This article will explore the application of both languages ​​in cloud computing and provide practical cases to illustrate their advantages.

C’s Applications

C is known for its high performance and low-level control. It is widely used in cloud computing, especially in the following areas:

• High Performance Computing (HPC): C can be used to build highly parallel and efficient HPC applications, such as Scientific models and financial simulations.
• Server-Side Applications: C is used to create server-side applications with high throughput and low latency, such as web servers and database systems.
• Game Development: C is a popular choice for game development because it provides low-level access to the hardware and underlying systems.

Practical case: Running C HPC application on Azure virtual machine

Use Visual Studio to create a C HPC application and deploy it to Azure virtual machine on board. The application uses the OpenMPI library for parallelization.

#include <mpi.h>
int main(int argc, char **argv) {
  // 初始化 MPI 库
  MPI_Init(&argc, &argv);
  // 获取 MPI 进程数和进程 ID
  int num_procs, rank;
  MPI_Comm_size(MPI_COMM_WORLD, &num_procs);
  MPI_Comm_rank(MPI_COMM_WORLD, &rank);
  // 执行并行计算
  // ...
  // 结束 MPI 库
  MPI_Finalize();
  return 0;
}

Applications of Python

Python is known for its ease of use, rich libraries, and extensive community support. It is widely used in cloud computing in the following areas:

• Data Science and Machine Learning: Python provides a wide range of data science and machine learning libraries such as NumPy, Pandas, and scikit- learn.
• Web Development: Python can be used to develop web applications and APIs using frameworks like Django and Flask.
• Script Automation: Python is often used to automate cloud management tasks, such as deploying applications and monitoring infrastructure.

Practical case: Use Python to deploy a machine learning model on AWS Lambda

Use scikit-learn to create a machine learning model, and use the Lambda function to convert the model to Deploy to AWS Lambda.

import numpy as np
from sklearn.linear_model import LinearRegression
# ... 训练模型 ...
lambda_handler = lambda event, context: {
    "body": str(model.predict(np.array(event["body"]))[0])
}
