+## Introduction to EC2:
+
+What is EC2, and why is it important?
+
+```
+- Amazon Elastic Compute Cloud (Amazon EC2) is a web service that provides secure, resizable compute capacity in the cloud.
+- Access reliable, scalable infrastructure on demand. Scale capacity within minutes with SLA commitment of 99.99% availability.
+- Provide secure compute for your applications. Security is built into the foundation of Amazon EC2 with the AWS Nitro System.
+- Optimize performance and cost with flexible options like AWS Graviton-based instances, Amazon EC2 Spot instances, and AWS Savings Plans.
+```
+
+EC2 usecases
+
+```
+Deliver secure, reliable, high-performance, and cost-effective compute infrastructure to meet demanding business needs.
+Access the on-demand infrastructure and capacity you need to run HPC applications faster and cost-effectively.
+Access environments in minutes, dynamically scale capacity as needed, and benefit from AWS’s pay-as-you-go pricing.
+Deliver the broadest choice of compute, networking (up to 400 Gbps), and storage services purpose-built to optimize price performance for ML projects
+```
+
+EC2 Instance Types
+
+Recommended to follow [this](https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/instance-types.html) page for very detailed and updated information.
+
+General purpose
+
+```
+General Purpose instances are designed to deliver a balance of compute, memory, and network resources. They are suitable for a wide range of applications, including web servers,
+small databases, development and test environments, and more.
+```
+
+Compute optimized
+
+```
+Compute Optimized instances provide a higher ratio of compute power to memory. They excel in workloads that require high-performance processing such as batch processing, 
+scientific modeling, gaming servers, and high-performance web servers.
+```
+
+Memory optimized
+
+```
+Memory Optimized instances are designed to handle memory-intensive workloads. They are suitable for applications that require large amounts of memory, such as in-memory databases,
+real-time big data analytics, and high-performance computing.
+```
+
+Storage optimized
+
+```
+Storage Optimized instances are optimized for applications that require high, sequential read and write access to large datasets. 
+They are ideal for tasks like data warehousing, log processing, and distributed file systems.
+```
+
+Accelerated computing
+
+```
+Accelerated Computing Instances typically come with one or more types of accelerators, such as Graphics Processing Units (GPUs),
+Field Programmable Gate Arrays (FPGAs), or custom Application Specific Integrated Circuits (ASICs). 
+These accelerators offload computationally intensive tasks from the main CPU, enabling faster and more efficient processing for specific workloads.
