What is AWS-: AWS ( amazon web services ) is the cloud company owned by amazon inc. . They provide users cloud based services like launching instances on there pre-configured hardware .By this client doesn't need and physical system client just need to tell what type of service the need. AWS not only provide us service to create instances there are many other services that are provides by AWS some of them are-:
- AWS Elastic Cloud Compute (EC2)
- AWS s3 (Simple Storage Services)
- Amazon Virtual Private Cloud (VPC)
- Amazon Cloud Front
- Amazon Relation Database Services (RDS) Creating own key pair , Security Group ,EBS Volume and Launching EC2 instance on AWS using these-:
Steps to download aws cli : click on this link and download .msi file (for windows) and install this in your system.
To create own security groups ,Key Pair ,ebs volume we firstly need AWS account. Follow these steps to create AWS account.
- Go to https://aws.amazon.com/console/ and click my account and then click on AWS management console
- After that click on create new account and fill all details that are asking and at last provide your credit card details and create account.
- Now Login your account. Your console look like this.
Now we need access key and secret access key to login in cli using your account but be sure do not share your these details with anyone.
To login open cli and type
you see this type of output-:
Put all details there like access key ID and secret access key
after that you are successfully login in your cli using your aws account.
What is security group?
Security group acts as a virtual firewall for your EC2 instances to control incoming and outgoing traffic. If we don't specify a security group, Amazon EC2 uses the default security group. We can add rules to each security group that allow traffic to or from its associated instances Creating own security group-:
syntax-:
aws ec2 create-security-group --description --group-name [--vpc-id ] [--dry-run | --no-dry-run] [--cli-input-json | --cli-input-yaml] [--generate-cli-skeleton ] [--cli-auto-prompt ]
if we login in aws account we can see our newly created security key-:
Creating Key pair -:
Creates a 2048-bit RSA key pair with the specified name. Amazon EC2 stores the public key and displays the private key for you to save to a file. The private key is returned as an unencrypted PEM encoded PKCS#1 private key. If a key with the specified name already exists, Amazon EC2 returns an error.
syntax-:
--key-name <value>
[--dry-run | --no-dry-run]
[--tag-specifications <value>]
[--cli-input-json | --cli-input-yaml]
[--generate-cli-skeleton <value>]
[--cli-auto-prompt <value>]
Creating Elastic Block Storage volume-: what is ebs?
An Amazon EBS volume is a durable, block-level storage device that you can attach to your instances. After you attach a volume to an instance, you can use it as you would use a physical hard drive. EBS volumes are flexible.
syntax-:
— availability-zone <value>
[ — encrypted | — no-encrypted]
[ — iops <value>]
[ — kms-key-id <value>]
[ — outpost-arn <value>]
[ — size <value>]
[ — snapshot-id <value>]
[ — volume-type <value>]
[ — dry-run | — no-dry-run]
[ — tag-specifications <value>]
[ — multi-attach-enabled | — no-multi-attach-enabled]
[ — cli-input-json | — cli-input-yaml]
[ — generate-cli-skeleton <value>]
[ — cli-auto-prompt <value>]
