Learning AWS need not be overwhelming. Start with the basics – just focus on these core services first, and once you get a hang of those, then move on to other services:
Networking
- VPC: Customize and secure your network with a virtual private cloud, ensuring scalable and secure connectivity for your AWS resources.
Compute
- EC2: Power your applications with scalable compute resources — essential for everything from hosting websites to processing large datasets.
Storage
- EBS, EFS, FSx, and S3: Practice using these storage options, from block storage with EBS, to scalable network storage with EFS and FSx, and durable object storage with S3.
Operations
- CloudWatch: Monitor your AWS resources and applications in real-time, enabling you to track performance and optimize your operations.
- CloudFormation: Automate your AWS infrastructure deployment with Infrastructure as Code (IaC) templates, ensuring consistent and repeatable configurations across your environments.
Master the basics, build a strong foundation, and then you’ll find it super easy to tackle the rest of AWS cloud.
You Should Know:
1. VPC Setup Command
Create a VPC using AWS CLI:
aws ec2 create-vpc --cidr-block 10.0.0.0/16
2. Launch an EC2 Instance
Start an EC2 instance with the following command:
aws ec2 run-instances --image-id ami-0abcdef1234567890 --instance-type t2.micro --key-name MyKeyPair
3. Create an S3 Bucket
Create a bucket using AWS CLI:
aws s3api create-bucket --bucket my-unique-bucket-name --region us-west-2
4. CloudWatch Alarm
Set up a CloudWatch alarm to monitor CPU usage:
aws cloudwatch put-metric-alarm --alarm-name CPUAlarm --metric-name CPUUtilization --namespace AWS/EC2 --statistic Average --period 300 --threshold 80 --comparison-operator GreaterThanOrEqualToThreshold --dimensions Name=InstanceId,Value=i-1234567890abcdef0 --evaluation-periods 2 --alarm-actions arn:aws:sns:us-west-2:123456789012:MyTopic
5. CloudFormation Template
Deploy a stack using a CloudFormation template:
aws cloudformation create-stack --stack-name MyStack --template-body file://mytemplate.yaml --parameters ParameterKey=KeyPairName,ParameterValue=MyKeyPair
What Undercode Say:
AWS is a powerful platform, and mastering its core services is the first step toward cloud expertise. Start with VPC for networking, EC2 for compute, and S3 for storage. Use CloudWatch for monitoring and CloudFormation for automation. These tools form the backbone of AWS, and once you’re comfortable with them, you can explore advanced services like Lambda, RDS, and DynamoDB. Remember, practice is key—use the commands and templates provided to build and manage your own AWS environment. For further learning, check out the AWS Documentation.
Additional Commands to Practice:
- List EC2 Instances:
aws ec2 describe-instances
- Delete S3 Bucket:
aws s3 rb s3://my-unique-bucket-name --force
- Create an EBS Volume:
aws ec2 create-volume --availability-zone us-west-2a --size 100 --volume-type gp2
- Attach EBS Volume to EC2:
aws ec2 attach-volume --volume-id vol-1234567890abcdef0 --instance-id i-1234567890abcdef0 --device /dev/sdf
- Create an EFS File System:
aws efs create-file-system --creation-token MyEFS
By mastering these commands and services, you’ll be well on your way to becoming an AWS cloud expert.
