Amazon Elastic Compute Cloud (EC2)

Elastic Compute Cloud (EC2) 

        EC2 is a virtual server in the AWS Cloud. AWS EC2 is short for AWS Elastic Cloud Compute,  For this no upfront investment is needed. You only pay for what you use. EC2 is secure and it is scalable.

   

Features of Amazon EC2 

Instances

    Virtual servers

Amazon Machine Images (AMIs)

     Preconfigured templates for your instances that package the components you need for your server (including the operating system and additional software).

Instance types

     Various configurations of CPU, memory, storage, networking capacity, and graphics hardware for your instances.

Key pairs

      Secure login information for your instances. AWS stores the public key and you store the private key in a secure place.

Instance store volumes

      Storage volumes for temporary data that is deleted when you stop, hibernate, or terminate your instance.

Amazon EBS volumes

       Persistent storage volumes for your data using Amazon Elastic Block Store (Amazon EBS).

Regions, Availability Zones, Local Zones, AWS Outposts, and Wavelength Zones

        Multiple physical locations for your resources, such as instances and Amazon EBS volumes.

Security groups

         A virtual firewall that allows you to specify the protocols, ports, and source IP ranges that can reach your instances, and the destination IP ranges to which your instances can connect.

Elastic IP addresses

         Static IPv4 addresses for dynamic cloud computing.

Tags

         Metadata that you can create and assign to your Amazon EC2 resources.

Virtual private clouds (VPCs)

         Virtual networks you can create that are logically isolated from the rest of the AWS Cloud. You can optionally connect these virtual networks to your own network.

 Guys , rather than theory parts i feel practicing makes everyone PRO , so we are directly skipping to the practice session.

Get Started With AWS EC2 - Hands-on

1) LAUNCH

2) CONNECT

2) USE

We are going to follow these three steps to launch an EC2 machine and now we are going to launch a server with Linux operating system.

Pre-requisites

1) AWS ACCOUNT - Free tier Eligible is enough 

2) putty.exe , puttygen  - both can be downloaded from putty.org

STEP 1 : LAUNCH 

  Open AWS console and search for EC2 on the search bar and click on launch instance

in next steps mention the instance name that you want to create and select the OS

after that need to choose instance type from the list 

Once done need to create a key pair usually this would be using RSA encryption method and private key file will be downloaded. There are two types of keys in AWS EC2 launching 

1.PEM- Privacy Enhanced Mail  

2.PPK-Putty Private Key

the next tab is for network settings where you can select or create your VPC (Virtual Private Connections) also customize your security groups.

Then you can configure your storage settings as per your needs and there is an advanced settings tab where you can select or create an IAM role , you can feed your user data and much more once everything was done click on launch instance.

Launching instance

Now you can see your server under the instances tab and it is ready to use 

STEP 2: CONNECT

Just select the instance to get public IP address or the instance ID to connect to the server 

open putty and manually input the Public IP address or the instance ID  under host name 

Then go to connection -> SSH -> Auth -> credentials and browse for your .ppk file (key pair you have downloaded while launching EC2 instance) , incase if you have downloaded the ,pem file use puttygen for .ppk generator.

    

Click open , and then click accept on this new window , now you have landed on your own server . 

to login key-in your default user name for Amazon linux machine which is ec2-user

Now you are created your own server and your are successfully logged in !!!!!!!! hoooooooooohooooo cooollll right ? 

Guess what ?  our next topic would be creating and connecting an EC2 windows server , be ready folks 😃
