Create EC2 instance from AWS Console

What is EC2 Instance?

Secure and resizable compute capacity in the cloud.

Amazon Elastic Compute Cloud ( Amazon EC2) is a web service that provides secure, resizable compute capacity in the cloud. It is designed to make web-scale cloud computing easier for developers.

In this article let us see how to create On-demand EC2 instance from Console.

Amazon EC2 evolution— How Nitro changed everything and Instance type deep dive


For those new to EC2, EC2 offers auto-scalable instances with compute, memory, storage and networking, deployable in multiple Availability zones/Regions while targetable by a load balancer along with management / administration tools such as AWS Systems Manager and AWS License Manager. EC2 instances are available under multiple purchase options such as SpotOn-DemandReserved and Savings Plan. It offers a broad choice of processors such as Intel, AMD and Amazon’s very own ARM-based Graviton processors. EC2 also allows the possibility of using Application Specific Integrated-Circuit (ASICs) and Field Programmable Gate-Array (FPGAs).

For those new to terms like ASIC and FPGA, they provide an alternate way to compute than CPU and GPU. Unlike CPU and GPU, which have a predefined instruction set and general purpose or parallel computing optimized , ASICs are dedicated, custom designed and optimized for one specific function (for e.g. bitcoin mining) whereas FPGAs are, as their name suggests, programmable digital logic cells. The hardware can be reprogrammed / repurposed to different workloads. Neither ASICs nor FPGAs have a predefined instruction set.

A very short history

Amazon launched EC2 with one instance type, m1, in the year 2006. This machine offered 1.7 GHz of CPU, 1.75 GB of RAM, 160 GB of disk and 250 Mbps of network bandwidth. This has evolved to 300+ instance types as of July 2020.

EC2 currently offers instance with upto 4.0GHz of CPU(z1d), 24576 GB / 24 TB of RAM(u-24tb1.metal), 48 TB of disk (d2.8xlarge) and 100 Gbps of Network bandwidth (High-Memory instances). Nitro turbo-charged this evolution in 2017 at which time “only” 42 instance types were available. It allowed new CPU architectures (ARM, AMD), bare metal offerings, 100 Gbps networking, EFA etc. So what exactly is Nitro?

Nitro — in english

Nitro refers to a whole fleet of changes, hardware and software, brought about in order to improve two important aspects of the infrastructure: performance and security. The basic idea is about offloading functions that are generally performed in a hypervisor stack to separate dedicated hardware / software component. Before Nitro — Networking, Storage, Security etc. were part of the hypervisor stack and contributed to about 30% of resource consumption that could not be used by customer instances.

With Nitro architecture, these components are moved out of the hypervisor stack, allowing for better resource consumption / performance and more controlled security.

How to Secure phpMyAdmin Access with Apache on Ubuntu 18.04

How to secure PHPMyAdmin login access in ubuntu apache on aws. Here, we will show you a simple 2 solution to secure PHPMyAdmin login in ubuntu apache on aws web server.

The first solution is to change the PHPMyAdmin login URL. And the second solution is add an extra security layer for access PHPMyAdmin login url in ubuntu 18.04 apache 2 on aws. And prevent the attacks.

Because by default, phpmyadmin login url is located on http:///phpmyadmin. So, The main reason of change phpmyadmin login url in ubuntu apache aws server to prevent attackers attack.

How to Secure phpMyAdmin with Apache 2 on Ubuntu 18.04

Now, you can see the following two solutions to secure PHPMyAdmin login access in ubuntu apache 2 on aws server.

Solution 1 – Change PhpMyAdmin Login Page URL in Apache 2 Ubuntu

In ubuntu, default phpmyadmin login url can be located at apache configuration that name apache.conf.

So, you can use sudo nano /etc/phpmyadmin/apache.conf command to open apache.conf file:

sudo nano /etc/phpmyadmin/apache.conf

Then, you can add the following line with your phpmyadmin url:

Alias /my-phpmyadmin /usr/share/phpmyadmin

Note that, you can replace my-phpmyadmin to your own word.

Now you need to restart apache 2 web server. So type the following command on your ssh terminal to restart apache service:

sudo service apache2 restart

Solution 2 – Secure PHPMyAdmin Access in ubuntu aws

Now, you can add extra security layer for access phpmyadmin login in ubuntu apache 2 on aws web server.

So, first of all, you need to create a password file with users using the htpasswd tool that comes with the Apache package. So open your ssh terminal and type the following command:

sudo htpasswd -c /etc/phpmyadmin/.htpasswd

Note that, You can choose any username instance of myAdmin with above command.

After that, one prompt box appear with password and confirm password. So, you can add password and confirm password here.

New password:
Re-type new password:
Adding password for user myAdmin

Now, you need to configure Apache 2 to password protect the phpMyAdmin directory and use the .htpasswd file.

So, open your ssh terminal and type the below command to open the phpmyadmin.conf file.

sudo nano /etc/apache2/conf-available/phpmyadmin.conf

Then add the following lines in phpmyadmin.conf file and save it:

Options  +FollowSymLinks +Multiviews +Indexes  ## edit this line
DirectoryIndex index.php

AllowOverride None
AuthType basic
AuthName "Authentication Required"
AuthUserFile /etc/phpmyadmin/.htpasswd
Require valid-user

Finally, restart apache web server by using the following command:

sudo service apache2 restart

Guide to Set up Ubuntu 16.04 on AWS EC2 Instance

In this tutorial, We will learn how to configure the Ubuntu 16.04 OS on AWS (Amazon Web Service) EC2 (Elastic Cloud Compute) Instance from scratch.

Sign up for AWS

  • Go to AWS signup page, if you don’t have an account already and continue with the process. For this you would need your Credit Card details (because instances will be charged based on the usage, we are just using free tier) and a valid phone number.

  • These are virtual machines which we are going to create can be requested and run from anywhere in the world, typically at some cost per hour (recently Amazon announced per second billing), per machine. Each virtual machine has a configurable number of CPUs and amount of memory and storage. We’re going to be using a free offering, but most organizations will need more resources to store and analyze their data.

Login and access to AWS services

  • After you log in, you should choose a region that is closest to you shown here. You could select the services you need. We will be select EC2 service under Compute.

  • On the EC2 dashboard, Click on ‘Launch Instance’ button in the section of Create Instance (as shown below).
