AWS Hands On

hey folks, as you know we have been doing blogs on AWS for a couple of days and we have gained some intermediate-level knowledge, now it's time to do some practice, so here is today's task we are going to do but this blog is going to be concise as this task are almost repetitive. If you found yourself stuck somewhere please let me know or you can follow previous blogs

Today'z Task

Task 01 :

Launch an EC2 instance using the AWS Management Console and connect to it using SSH.

Install a web server on the EC2 instance and deploy a simple web application.

Monitor the EC2 instance using Amazon CloudWatch and troubleshoot any issues that arise.

Let do this in a sequence

Launch an EC2 instance using the AWS Management Console and connect to it using SSH.

SSH successfully

Install a web server on the EC2 instance and deploy a simple web application.

we are going to install apache server , but first need to update the system

Let us install an Apache web server, using:

sudo apt-get update
sudo apt-get install apache2 -y
## verify the install by
service apache2 status

copy the instance IP address and run it on the browser , make sure you have allowed Http protocol in security group.

installed the apache2 server successfully

Monitor the EC2 instance using Amazon CloudWatch and troubleshoot any issues that arise

In your EC2 Console > Select the Instance you want to monitor > Go to the Monitoring Tab > Click on Manage Detailed Monitoring

.Enable the Detailed Monitoring in the pop-up and click on Confirm

Once done, Navigate to CloudaWatch > Metrics > All Metrics > Select EC2

Click on Per-Instance Metrics > And select the Metrics you want to monitor > I am selecting CPU Utilization

Now let us create the Alarm.

Go to Alarms > All Alarms > Create Alarm > Select Metric > Select EC2 > Select Per Instance Metrics > Select the CPU Utilization > Click on Select Metric

Under conditions, select the Threshold value to be greater than 50 > Click on Next.

Set up the SNS topic and create an alarm. I am naming

Task-02

• Create an Auto Scaling group using the AWS Management Console and configure it to launch EC2 instances in response to changes in demand.

• Use Amazon CloudWatch to monitor the performance of the Auto Scaling group and the EC2 instances and troubleshoot any issues that arise.

• Use the AWS CLI to view the state of the Auto Scaling group and the EC2 instances and verify that the correct number of instances are running.

let's perform these task one by one

Create an Auto Scaling group using the AWS Management Console and configure it to launch EC2 instances in response to changes in demand.

make an ec2 instance with minimum specification

Go to EC2 Console > Select the EC2 Instance > Actions > Image and templates > Create a template from the instance

you can verify the created template in Launch Template

Go to your EC2 console > Under Auto Scaling > Select Auto Scaling Groups > Create Auto Scaling Groups >

Auto Scaling group name: test-ASG

Launch template: Select the launch template you created

now click on next

In the next section > Select a couple of availability zones > Click on Next > Enable Monitoring > Click on Next

Set the Group size as per your requirement

you can also add a notification that triggers at the time of scaling and a tag

Review and Create your ASG

In the EC2 Instances dashboard, you can see that the number of instances has increased to three (as per your requirement).

Use Amazon CloudWatch to monitor the performance of the Auto Scaling group and the EC2 instances and troubleshoot any issues that arise.

You can see that the Target tracking policy has created two more alarms:

Go to the ASG we created > Enable ASG Metric.

Let us create an Alarm for the same ASG.

create alarm > select matrix > auto scaling > select group > confirm matrix

now from here we can monitor the performance of the Auto Scaling group and the EC2 instances and troubleshoot any issues that arise.

Use the AWS CLI to view the state of the Auto Scaling group and the EC2 instances and verify that the correct number of instances are running.

create a User with access to ec2 instance > then down load AWS CLI from the given command

for the creation of IAM User and AWS CLI you can follow previous blogs

update the terminal and download AWS CLI

sudo apt update
sudo apt-get install awscli
aws --version

now to view the state of the Auto Scaling group and the EC2 instances and verify that the correct number of instances are running

Configure AWS CLI with access key and secret key

Let us see the ASGs by using the:

aws autoscaling describe-auto-scaling-groups

Let us verify the ec2 instances:

aws ec2 describe-instances

woohoo, that's all for the day
