Amazon EC2
Amazon EC2-a computer in the cloud |
Refers - the amount of computational power required to fullfill your workload |
If workload small-website that receive few visitors, - then your compute needs of workload is very small |
EC2-Elastic Computional Cloud |
Elastic-You can decrease the amount of servers required by an application automatically based on the current demand |
Compute-refers to the compute or server, resources that are being presented |
Cloud-refers to the fact that these are cloud-hosted compute resources |
OS-Supported Windows and Linux such as Redhat, SUSE, Ubuntu |
Amazon Machine Images-(AMI)-create images of your server at any time and can be reused to launch instances in the future |
offers native support for the IPV6 Protocol |
Can be enabled through AWS Management Console, Software Development Kit, and Command Line interface(CLI) |
Benefits of AWS EC2
Scalable: Add more instances when you need them; terminate them when you do not. |
Optimizable: Choose from instance types optimized for compute, memory, storage, accelerated computing and general purpose. Each instance type has a variety of sizes. To learn more about instance types see |
Amazon Machine Image(AMI)
An AMI is a template that contains a software configuration. For example, an operating system, an application server, and applications. |
From an AMI, you launch an instance, which is a copy of the AMI running as a virtual server in the cloud. |
You must specify a source AMI when you launch an Amazon EC2 instance. |
You can launch multiple instances from a single AMI when you need multiple instances with the same configuration. |
You can use different AMIs to launch instances when you need instances with different configurations. |
Amazon EC2 Pricing
There are four ways to pay for Amazon EC2 instances: On-Demand, Reserved Instances, Spot Instances, and Dedicated Hosts. |
Amazon EC2 usage of Linux- and Ubuntu-based instances that are launched in On-Demand, Spot, and Reserved are billed on one-second increments, with a minimum of 60 seconds. |
All other types of OS are billed by the hour. |
The minimum unite of time that will be charged is a minute, but after your first minute of time, we can account for seconds. |
However, if you start then stop an instance in 10 seconds, you will be charged the 60 seconds not 10. |
Dedicated Hosts provide you with Amazon EC2 instance capacity on physical servers dedicated for your use. |
Broad set of Compute Instance Types
Instance types comprise varying combinations of CPU, memory, storage, and networking capacity |
give you the flexibility to choose the appropriate mix of resources for your applications. |
Each instance type includes one or more instance sizes, which allows you to scale your resources to the requirements of your target workload. |

Choosing the Right Amazon EC2 Instance
The Considerations of choosing instance -Core count, Memory Size, storage size & type, network performance, CPU Technologies |
Dimensions of new instances that are controlled by the instance type and Amazon Machine Image (AMI) for images launched on AWS: 1. Amount of virtual hardware dedicated to the instance 2. Software loaded on the instance |
there are multiple sizes of Instances:- Large, XLarge, 2XLarge, etc. |
Amazon EC2 provides different instance types to enable you to choose the CPU, memory, storage, and networking capacity that you need to run your applications. |
Per second Billing
With per-second billing, you pay for only what you use. |
It takes cost of unused minutes and seconds in an hour off of the bill, so you can focus on improving your applications instead of maximizing usage to the hour. |
Amazon EC2 usage are billed on one second increments, with a minimum of 60 seconds. |
Similarly, provisioned storage for EBS volumes will be billed per-second increments, with a 60-second minimum. |
Per-second billing is available for instances launched in: |
• On-Demand, Reserved and Spot forms • All AWS Regions and Availability Zones • Amazon Linux and Ubuntu |
AWS Lambda - Introduction
an event-driven serverless compute service. |
Lambda lets you run code without provisioning or managing servers. |
You pay only for the compute time you consume - there is no charge when your code is not running. |
How does AWS Lambda Works ?
Lambda executes your code only when needed and scales automatically to thousands of requests per second |
With Lambda, you can run code for virtually any type of application or backend service - all with zero administration |
Just upload your code and Lambda takes care of everything required to run and scale your code with high availability |
You can set up your code to automatically trigger from other AWS services or call it directly from any web or mobile app. |
It should be noted that function execution on Lambda is limited to a maximum of 5 minutes. |
Lambda Key Benefits
You only pay for the compute you use. You don’t pay for compute time when your code is not running.This makes AWS Lambda ideal for variable in intermittent work loads. |
You can run code for virtually any application or backend service, all with zero administration, including server and operating system maintenance. Just upload your code and Lambda takes care of everything required to run and scale your code with high availability. |
You can set up your code to automatically trigger from other AWS services, or call it directly from any web or mobile app. |
Lambda supports a variety of different programming languages including Go, NodeJS, Java, C#, and Python. |
