AWS Services - Elastic Compute Cloud (EC2)
Introduction to AWS EC2: Scalable Compute Power in the Cloud -
First Going into EC2 let’s understand about what is AWS - Amazon Web Services (AWS) is a cloud computing platform that offers services like storage, computing, and content delivery. It's owned by Amazon and is used by millions of customers, including startups, large enterprises, and government agencies.
What is Amazon EC2 (Elastic Compute Cloud)?
Amazon Web service offers EC2 which is a short form of Elastic Compute Cloud (ECC) it is a cloud computing service provided by the Cloud Service Provider AWS. You can deploy your applications in EC2 servers without any worrying about the underlying infrastructure. You configure the EC2-Instance in a very secure manner by using the VPC, Subnets, and Security groups. You can scale the configuration of the EC2 instance you have configured based on the demand of the application by attaching the autoscaling group to the EC2 instance. You can scale up and scale down the instance based on the incoming traffic of the application.
Define EC2 (Elastic Compute Cloud) and its purpose.
Explain that EC2 allows users to run virtual machines (instances) on-demand in the cloud, avoiding the need to maintain physical hardware.
Mention the different instance types available based on use cases (e.g., compute-optimized, memory-optimized, etc.).
Use Cases of Amazon EC2 (Elastic Compute Cloud) -
Web Hosting: How EC2 can be used for hosting websites and applications.
Big Data and Analytics: Discuss EC2’s role in data processing, machine learning, and analytics workloads.
Development and Testing: Explain how developers use EC2 for testing and staging environments.
Disaster Recovery: Discuss EC2's role in providing backup and disaster recovery solutions.
AWS EC2 Instance Types -
Different Amazon EC2 instance types are designed for certain activities. Consider the unique requirements of your workloads and applications when choosing an instance type. This might include needs for computing, memory, or storage.
General Purpose Instances
Compute Optimized Instances
Memory-Optimized Instances
Storage Optimized Instances
Accelerated Computing Instances
As the given name it’s itself defines what kind of works performed.
AWS EC2 Operating Systems -
Amazon EC2 includes a wide range of operating systems to choose from while selecting your AMI. Not only are these selected options, but users are also even given the privilege to upload their own operating systems and opt for that while selecting AMI during launching an EC2 instance. Currently, AWS has the following most preferred set of operating systems available on the EC2 console.
Windows Server
Ubuntu Server
SUSE Linux
Red Hat Linux
Pricing of AWS EC2 (Elastic Compute Cloud) Instance -
The pricing for AWS EC2 instances varies based on the type of instance you choose. Here's a breakdown of the most common pricing models:
1. On-Demand Instances
This model follows a pay-as-you-go approach, where you only pay for the time the instance is running.
When the instance is stopped, billing stops as well. You're charged based on the running time of the EC2 instance.
2. Reserved Instances
Reserved Instances allow you to commit to using an EC2 instance for a fixed term (typically 1 or 3 years).
In exchange for your commitment, AWS offers a discounted price, making it a cost-effective option for long-term usage.
3. Spot Instances
Spot Instances let you bid for unused EC2 capacity. The highest bid wins, and you get the instance at a lower price.
However, data stored on Spot Instances can be lost if AWS needs the capacity back, so they are not ideal for persistent data storage.
Each pricing model offers flexibility depending on your usage patterns, allowing you to choose the best option based on your needs and budget.
