• EBS allows for better data management by enabling users to detach volumes, take snapshots, back up data, and reattach as needed—similar practices are common in physical infrastructure.

• Knowledge of storage-related services like EFS (Elastic File System) is also important; these services help manage large amounts of data generated by applications effectively.

• S3 buckets are highlighted as a widely used storage solution due to their cost-effectiveness and scalability. AWS has made encryption mandatory for S3 storage, enhancing security.

Importance of IAM in AWS

• Identity and Access Management (IAM) is introduced as a crucial component for managing permissions across various tools and applications within AWS.

• IAM enables organizations to configure user permissions carefully—for instance, developers may have write access while QA engineers might only have read access to repositories.

• The necessity of restricting admin access is emphasized; this prevents unauthorized changes or deletions that could disrupt project integrity.

Understanding AWS Monitoring and Serverless Computing

This section delves into the importance of monitoring in AWS, specifically through CloudWatch, and introduces the concept of serverless computing with AWS Lambda.

The Importance of Monitoring in AWS

• Key Services: Management is crucial for effective cloud operations; understanding services like CloudWatch is essential.

• Monitoring and Observability: These are fundamental concepts in DevOps and Site Reliability Engineering (SRE), critical for building reliable, sustainable, and highly available applications.

• CloudWatch's Role: It monitors all actions within AWS. For instance, it can track when a developer creates an S3 bucket or EBS volume.

• Triggering Actions: CloudWatch can trigger notifications if certain conditions are met, such as alerting when an unencrypted EBS volume is created against compliance rules.

• Guardrails for Compliance: As a DevOps engineer, you ensure that AWS usage aligns with organizational policies by monitoring activities and enforcing security measures.

Integrating CloudWatch with Lambda

• Combining Services: Using CloudWatch alongside Lambda allows for automated responses to specific events, such as sending email notifications about compliance violations.

• Lambda Overview: Lambda functions enable serverless computing where actions can be executed without managing servers directly.

• Serverless vs. EC2 Instances: Unlike EC2 instances that require manual setup and management, Lambda automatically handles execution environments based on your code requirements.

• Automated Execution: With Lambda, you don't need to specify underlying infrastructure; it automatically provisions resources needed to run your code temporarily.

• Introduction to Cloud Build Services as a continuation of the previous topics; highlights their role in CI/CD processes.

• Emphasis on the need for awareness of AWS's build services that facilitate continuous integration and delivery (CI/CD).

Understanding CI/CD with AWS Tools

• Key AWS CI/CD tools include AWS CodePipeline, AWS CodeBuild, and AWS CodeDeploy.

• Continuous Integration and Continuous Delivery are crucial responsibilities for DevOps engineers; familiarity with these concepts is essential.

• CodePipeline functions similarly to Jenkins pipelines by defining actions and event targets within a deployment process.

Detailed Functionality of CI/CD Tools

• CodeBuild is described as a fully managed service that compiles code, runs tests, and produces software packages.

• CodeDeploy automates application deployment onto EC2 instances or on-premises servers after artifacts are built through CI processes.

Considerations for Using AWS CI/CD Services

• Organizations using Jenkins should evaluate whether to transition to AWS's native build services based on their cloud strategy (single vs. multi-cloud).

• If planning future migrations between cloud platforms (e.g., from AWS to Azure), it may be prudent not to rely solely on platform-specific build services.

Monitoring Cloud Configuration

• Importance of monitoring cloud configurations is highlighted; this is facilitated by the AWS Config Service, which acts as a guardrail service.

• The service allows users to track configurations like unencrypted EBS volumes or improperly configured S3 buckets while enabling remedial actions.
