AWS CodeStar:

An integrated service that provides a unified user interface to manage software development activities. It simplifies the process of setting up a CI/CD pipeline with its project templates and tight integration with AWS services.

4. AWS Monitoring and Logging Services

Monitoring and logging are essential to maintain the reliability, availability, and performance of applications in production.

Amazon CloudWatch:

A monitoring service for AWS resources and applications. It provides metrics, logs, and alarms, helping you monitor application performance and identify issues in real-time.

AWS CloudTrail:

A service that enables governance, compliance, and operational and risk auditing of your AWS account. It provides event history of AWS API calls, helping you track changes and maintain security.

AWS X-Ray:

A service that helps with debugging and analyzing applications, especially those built using microservices architecture. X-Ray provides a visual representation of the application’s performance, making it easier to identify bottlenecks and optimize performance.

5. AWS Security and Identity Services

Security is a top priority in cloud environments, and AWS offers various services to manage access and maintain security best practices.

AWS Identity and Access Management (IAM):

A service that enables fine-grained access control and management of AWS resources. With IAM, you can define roles, policies, and permissions for users, groups, and applications.

AWS Secrets Manager:

A service to securely store and manage sensitive information, such as database credentials, API keys, and other secrets.

AWS Shield & WAF (Web Application Firewall):

AWS Shield provides protection against DDoS attacks, while WAF allows you to monitor and control HTTP requests to prevent malicious activity. Both services are essential for maintaining the security of applications.

6. AWS Infrastructure as Code (IaC) Tools

Infrastructure as Code (IaC) is a fundamental practice in DevOps, enabling teams to manage and provision infrastructure using code. AWS provides several tools that facilitate IaC.

AWS CloudFormation:

A service that allows you to model and set up AWS resources using JSON or YAML templates. It provides a declarative approach to managing infrastructure, making it easy to create, update, and manage resources consistently.

AWS CDK (Cloud Development Kit):
