As a DevOps engineer, here are the top 10 AWS services that you should be familiar with:
Amazon EC2 (Elastic Compute Cloud):
It provides scalable virtual servers in the cloud. DevOps engineers use EC2 to deploy applications and run workloads.
For example, you can create EC2 instances to host web servers for your application.
Please take a quick look at the official documentation to read more: https://aws.amazon.com/ec2/
AWS Lambda:
It is a serverless compute service that allows you to run your code without managing servers. DevOps engineers use Lambda for building event-driven architectures.
For example, you can use Lambda to process and analyze data from an AWS S3 bucket whenever a new file is uploaded.
Please take a quick look at the official documentation to read more: https://aws.amazon.com/lambda/
Amazon S3 (Simple Storage Service):
It is a scalable object storage service for storing and retrieving data. DevOps engineers commonly use S3 for storing backups, static assets, and data archives.
For example, you can store static website files in S3 and serve them via Amazon CloudFront.

AWS CodePipeline:
It is a continuous integration and delivery service. DevOps engineers use CodePipeline to build, test, and deploy applications.
For example, you can set up a pipeline that automatically builds and deploys your application code to AWS Elastic Beanstalk whenever changes are committed to a Git repository.
Please take a quick look at the official documentation to read more: https://aws.amazon.com/codepipeline/
AWS CloudFormation:
It is an infrastructure-as-code service for provisioning and managing AWS resources. DevOps engineers use CloudFormation to define and automate infrastructure using templates.
For example, you can create a CloudFormation template to provision an entire application stack, including EC2 instances, RDS databases, and load balancers.
Please take a quick look at the official documentation to read more: https://aws.amazon.com/cloudformation/
AWS CloudWatch:
It is a monitoring and observability service. DevOps engineers use CloudWatch for collecting and analyzing metrics, logs, and events from AWS resources and applications.
For example, you can set up CloudWatch alarms to notify you when your EC2 instances' CPU utilization exceeds a certain threshold.
Please take a quick look at the official documentation to read more: https://aws.amazon.com/cloudwatch/
AWS Elastic Beanstalk:
It is a fully managed service for deploying and scaling applications. DevOps engineers use Elastic Beanstalk to simplify application deployment and management.
For example, you can deploy a web application by simply uploading your code package, and Elastic Beanstalk takes care of provisioning and scaling the necessary resources.
Please take a quick look at the official documentation to read more: https://aws.amazon.com/elasticbeanstalk/
AWS CodeDeploy:
It is a deployment service that automates application deployments to various compute services. DevOps engineers use CodeDeploy to manage application deployments across EC2 instances, on-premises servers, and Lambda functions.
For example, you can use CodeDeploy to deploy a new version of your application to a fleet of EC2 instances in an auto-scaling group.
Please take a quick look at the official documentation to read more:
AWS Systems Manager:
It provides a unified interface for managing AWS resources and running operational tasks. DevOps engineers use Systems Manager for configuration management, patching, and automation.
For example, you can use Systems Manager to automate the patching of EC2 instances and manage inventory across your infrastructure.
Please take a quick look at the official documentation to read more: https://aws.amazon.com/systems-manager/
AWS CloudTrail:
It provides detailed auditing and monitoring of API activity in your AWS account. DevOps engineers use CloudTrail to track changes to resources, troubleshoot issues, and ensure compliance.
For example, you can use CloudTrail to track API calls made to create or modify security groups, allowing you to review and audit any changes made.
Please take a quick look at the official documentation to read more: https://aws.amazon.com/cloudtrail/
These services provide a solid foundation for DevOps engineers to implement continuous integration, continuous delivery, infrastructure automation, monitoring, and scalability in their projects on the AWS platform.
