Amazon Web Services (AWS) provides a variety of tools to develop, deploy, and troubleshoot applications. These tools are essential for individuals planning to take the AWS Certified Cloud Practitioner (CLF-C02) exam. This exam provides a comprehensive evaluation of the exam-taker’s ability to demonstrate knowledge of how to architect and deploy secure and robust applications on AWS technologies.
The Development Tools
AWS Cloud9
AWS Cloud9 is an integrated development environment (IDE) that allows you to write, run, and debug code with just a web browser. With Cloud9, you can share your coding environment with your team, making collaborative coding and troubleshooting easy and efficient. The example below illustrates how to use AWS Cloud9 to create a simple Python script:
print(“Welcome to AWS Cloud9!!”)
To run this script, you can simply use Cloud9’s built-in command line and execute:
python script.py
AWS CodeStar
AWS CodeStar is a cloud-based service for creating, managing, and working with software development projects on AWS. CodeStar comes with an automated CI/CD pipeline, making the deployment of applications swift and effective.
For instance, to develop a sample web service, you will use CodeStar to prescribe a development project. On creating the project, CodeStar automatically sets up a continuous delivery toolchain and creates a Git repository for source control.
The Deployment Tools
AWS CodeDeploy
AWS CodeDeploy automates code deployments to any instance, including Amazon EC2 instances and servers running on-premise. CodeDeploy automates the deployment process making it more reliable, faster and safer.
AWS Elastic Beanstalk
AWS Elastic Beanstalk provides an easy-to-use service for deploying and scaling web applications developed with Java, .NET, PHP, Node.js, Python, Ruby, Go, and Docker. With Elastic Beanstalk, you can quickly deploy and manage applications without worrying about the infrastructure that runs those applications.
The Troubleshooting Tools
AWS CloudTrail
AWS CloudTrail is a service that provides governance, compliance, operational auditing, and risk auditing of your AWS account. With CloudTrail, you can troubleshoot by identifying which users and accounts called AWS, the source IP address from which the calls were made, and when the calls occurred.
AWS CloudWatch
AWS CloudWatch is a monitoring service for AWS resources and the applications you run on AWS. You can use Amazon CloudWatch to collect and track metrics, collect and monitor log files, and set alarms.
In summary, understanding these development, deployment, and troubleshooting tools is essential for any AWS Certified Cloud Practitioner. A good understanding of these tools not only builds proficiency in managing applications but also aids in passing the AWS Certified Cloud Practitioner (CLF-C02) exam.
