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

Introduction

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 Spot, On-Demand, Reserved 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.

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.

How To Optimize AWS EC2 Costs

Incepted with the aim of reducing costs of acquiring hardware upfront, the Amazon Elastic Compute Cloud (EC2) of the Amazon Web Services (AWS) has made development and deployment relatively faster and less costly. However, the retaining costs from some unused storage, Instances, and features of the Amazon EC2 remain a glitch in EC2 cost-effectiveness.

In this article, I’ll be highlighting some ideal ways to optimize your AWS EC2 costs using;

• Amazon provided cost management tools and some

• Best practices for reducing your Amazon Web Service EC2 bills

AWS Costs Management Tools

Amazon has provided us with a good number of analytics and automation tools to help streamline AWS data analysis and otherwise, heavy tasks. I’ve listed a number of these tools, with a brief explanation of how they work and how you can use them to optimize and reduce your AWS EC2 costs.

How to Create EC2 Instance in AWS — Tutorial for Beginners

EC2 stands for, Elastic Compute Cloud. It is a part of Amazon’s cloud-computing platform, Which allows users to rent virtual computers on which they can run their own computer applications. Creating and using the EC2 instance is very simple. Following are the steps:

Step 1: Create an Account in EC2

1.1) Go to and the following screen will get a display.

1.2) Click on “Create an AWS Account”

1.3) Start filling the account creation form.

You will require your email Id, Phone Number, and Credit/Debit card details. AWS is free for 12 months, however, it is mandatory to fill in payment details to create an account.

1.4) After filling in all the required information, your account will get created. Within 24 hours all the services (like EC2) will get activated on your account. (but mostly it take 5-10 minutes)
