AWS Service - Elastic Compute Cloud(EC2)

EC2:

Create EC2 instance( Windows & Linux):


create EC2:

search ec2 service -> launch instance -> choose amazon linux (freetier) -> choose t2 micro -> leave the configure instance default -> leave the default storage option -> tags give name like (Name Linux-server) -> create new security group and add the ports (ssh/http/all-icmp) -> create a new key pair for the login password




Linux Machine: 

To connect the EC2 - we need either putty or MobaXterm

open MobaXterm - > session -> ssh -> public ip -> username = ec2-user -> advanced settings (use private key and choose the key we downloaded) 




Windows machine: 

login using username = Administrator (use get password feature in instance connect to upload your .pem key and generate the password)

search rdp and give public ip and user name "Administrator" and give the generated password



Linux website: 

– Create a website in Linux server :

  1. yum install httpd ( host a website)

  2. cd /var/www/html

  3. vi index.html  

(ESC i - type your content

ESC:wq! - to save the content  and force-quit )

  1. systemctl restart httpd

  2. systemctl enable httpd (permanent service enable) 

            to delete a line 

  1. ESC dd



Windows Website: 

after login - search for "server manager" add roles and features select webserver(IIS) Internet Information Service

go to website default path = c:inetpub/wwwroot
edit the default website 

User ADD:

useradd pravin
passwd pravin

vi /etc/ssh/sshd_config
  PasswordAuthentication yes

systemctl restart sshd
visudo
esc /root - search the word root
esc yy - to copy the line
esc p - to paste it in next line and edit it to change the root to pravin (example below)
 root ALL=(ALL)   ALL
 pravin ALL=(ALL) ALL

Types of Instance:

  • On-demand instance -

                        Depending on our need, whenever if we build an EC2 instance is called on              

                        demand  (1000 rs - rough calculation)             

                   

  • reserved instance  

                       we can purchase an instance for a specific period of time  (30 % discount - 700 rs) 


  • Spot instance

                       70 % - 300rs - 12 hours auto terminate  


  • Scheduled instance 

scheduling an instance build for a certain time 


  • Dedicated host

Dedicated HW for end-user 

Types of EC2 instance (resource)  refer :

https://aws.amazon.com/ec2/instance-types/

Changing RAM & Storage in Linux Server:

instance right click -> instance-settings -> change instance type

– Before Changing: 



– After Changing:

AWS Service: Auto Scaling & SNS

Image
  Auto Scaling: – When the load is increasing in Load Balancers autoscaling will automatically increase the instances in Load balancers – Practical steps: create an AMI  use the AMI for the Autoscaling configurations  Add the AMI in Launch configuration  Now create the rule using Auto scaling groups  create an ALB and attach it to the auto-scaling group.  – Launch autoscale: – Create Autoscaling: – Instance created automatically: – Tested with Load Balancer: Target tracking - it will increase or decrease with a single value  step scaling - step by step  simple scaling - overall increase – To check autoscale adding load to CPU: – Sample script to increase CPU load: Inside machine: vi load.sh #!/bin/bash dd if=/dev/zero of=/dev/null bs=50000 count=1000000 vi for.sh #!/bin/bash for i in {1..10} do         sh load.sh done chmod a+x load.sh chmod a+x for.sh – Instance launched automatically: – Automatically attac...

AWS Service: ALB(Application Load Balancer):

  ALB(Application Load Balancer): – Practical steps: Create 6 instances  - 2 instance (main website)  - 2 instance (image)  - 2 instance (video)    Create ALB  Create target groups Add the target group to Listeners  – Comment to run the script(built the website): #!/bin/bash sudo yum -y install httpd sudo echo "This is E-commerce-main server" > /var/www/html/index.html sudo systemctl restart httpd sudo systemctl enable httpd –Script to create sub folder for website: #!/bin/bash sudo yum -y install httpd sudo mkdir /var/www/html/videos sudo echo "This is Video server" > /var/www/html/videos/index.html sudo systemctl restart httpd sudo systemctl enable httpd – Example: – Ec2 creating: – EC2 web Launch: – Main web: – Subfolder: – Adding all instances in Load Balancer (Single website): – Creating LB: – Creating TG: – Adding Subfolder in Target Group: – TG group added in Listener: – LB check: – Creating Hyperlink in Load Balancer for Website
