View source for How to create Amazon EC2 instance and perform login using SSH

* Login to the EC2 management console:
: https://console.aws.amazon.com/ec2/
* From the upper pane, it is strongly recommended to select a region close to your location
: Note: There might be pricing differences between AWS regions. For more information, see:
: https://aws.amazon.com/ec2/pricing/
* From the left pane -> Instances -> Instances -> click on “Launch Instance” -> select the relevant Amazon Machine Image. 
* From the “Choose an Instance Type”, select machine type according to your needs. 
: For more information, see:
: https://aws.amazon.com/ec2/instance-types/
* Click on “Next: Configure Instance Details”
* Configure Instance Details page:
:* Number of instances – unless you need redundancy, leave the default value
:* Purchasing option - In case you do not need permanent EC2 machine for development / test environments, and would like to save money, consider using EC2 spot instance. For more information, see:
: https://aws.amazon.com/ec2/spot/
* Network – Select the relevant VPC (Virtual Private Cloud). For more information on creating a VPC, see:
: https://docs.aws.amazon.com/AmazonVPC/latest/GettingStartedGuide/getting-started-ipv4.html
* Subnet – Select the relevant subnet and availability zone. For more information on creating subnets, see:
: https://docs.aws.amazon.com/AmazonECS/latest/developerguide/create-public-private-vpc.html
* Auto-assign Public IP – Leave the default settings
* IAM role - Choose the relevant Amazon IAM role. For more information on creating IAM roles, see:
: https://docs.aws.amazon.com/IAM/latest/UserGuide/id_roles_create.html
•	Shutdown behavior – Choose either Stop (the instance will be shut down, but it’s content will remain) or Terminate (the instance content will be permanently removed)
•	Enable termination protection – This option protect the instance content from been permanently removed when selecting “Terminate instance” from the management console. This option is not relevant for Spot instances
•	Monitoring – Allows you to monitor the performance of the instance; however, there is additional cost for using this service. For more information, see:
https://aws.amazon.com/cloudwatch/pricing/
•	Tenancy – Leave the default settings (unless you have specific requirement, at additional cost, to choose a dedicated hardware without sharing it with other customers)
•	Network interfaces – Leave the default settings
•	Advanced Details – under “User data”, you can specify post-login script (for example, update security patches, install additional components, etc.)
7.	Click on “Next: Add Storage”
8.	From the “Add Storage” page, feel in the following details:
•	Specify the root device volume size
•	Select the Volume type according to your needs. For more information, see:
https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/EBSVolumeTypes.html
•	In case you need additional storage (for example, split between OS drive and data drives), click on “Add New Volume”
•	When adding additional volumes, it is recommended to encrypt all the additional volumes (there is no performance impact)
9.	Click on “Next: Add Tags”
10.	Click on “Add Tag”:
•	Key – Specify here ”Name”
•	Value – Specify here the instance host name
11.	It is recommended to add additional tags (such as project name, environment, etc.). For more information, see:
https://aws.amazon.com/answers/account-management/aws-tagging-strategies/
12.	Click on “Next: Configure Security Group”
 
13.	From the “Configure Security Group” page, select either to create a new security group or to select an existing security group.
•	When creating a new security group, specify an informative “Security group name” and description.
•	When configuring security groups for publicly accessible EC2 instances, it is highly recommended to avoid opening SSH / RDP access from the internet to the EC2 instances – restrict access to the EC2 instances from a static public IP address or your organization public address/subnet
14.	Click “Review and Launch” -> click on Launch
15.	On the “Select an existing key pair or create a new key pair” page:
•	“Create a new key pair” and specify key pair name – if this is your first EC2 instance in this specific region -> click on “Download Key Pair” to download the private key file -> save this key in a secure location, since it allows access to your EC2 instances
•	“Choose an existing key pair” – if you already created and download the private key file, select an existing key pair -> click on “I acknowledge”
16.	Click on “Launch Instances” -> click on “View Instances”
17.	Wait for the EC2 instance to switch its state to “running”


Login to EC2 instance (from Windows machine)
1.	Download puttygen.exe from:
http://www.chiark.greenend.org.uk/~sgtatham/putty/download.html
2.	Run the puttygen.exe
3.	Click on “Load” -> change the file extension from “Putty Private key files” to “All Files” -> locate the private key pair and click on Open -> click on OK -> click on “Save private key” -> click on “Yes” -> save the private key file with PPK extension -> close puttygen.exe
4.	Download Putty from:
https://www.chiark.greenend.org.uk/~sgtatham/putty/latest.html
5.	Run putty.exe
6.	From the left pane, under “Connection” -> expand SSH -> click on “Auth” -> from the main pane, under “Authentication parameters”, click on “Browse” -> locate the SSH private key generated by puttygen.exe
7.	From the left pane, click on “Session” -> from the main pane, under “Host Name (or IP address)” specify the following:
ec2-user@IP_Address
Note: Replace IP_Address with the EC2 instance “IPv4 Public IP” or “Public DNS (IPv4)”
8.	Under “Saved Sessions”, specify a name for this newly created connection.
9.	Click on Save
10.	Click on Open
Login to EC2 instance (from Linux machine)
1.	Login to the Linux machine console.
2.	Copy the private key file into ~/.ssh of the currently running user
3.	Run the following command:
ssh ec2-user@IP_Address -i ~/.ssh/[KEY_FILENAME]
Note 1: Replace IP_Address with the EC2 instance “IPv4 Public IP” or “Public DNS (IPv4)”
Note 2: Replace KEY_FILENAME with the actual private key file name
