Welcome back to our #100DaysOfAWS series! On Day 11, we're diving deep into the heart of Amazon Web Services—EC2 (Elastic Compute Cloud). Understanding EC2 is fundamental to leveraging the full potential of AWS, and today's journey will take us through the basics, history, and a hands-on exploration of different EC2 instance types. By the end of this blog, you'll launch your first EC2 instance, marking a pivotal milestone in your AWS learning journey.
Understanding EC2 Basics:
Amazon EC2, the backbone of AWS, provides scalable compute capacity in the cloud. It allows you to run virtual servers, known as instances, tailored to your specific needs. Before we delve into the intricacies, let's take a quick look at the history that led to the creation of EC2.
A Glimpse into EC2's History:
Launched in 2006, EC2 marked a revolutionary shift in cloud computing. It freed organizations from the constraints of physical servers, enabling them to scale their compute resources dynamically. This shift was monumental; businesses no longer needed to plan and procure physical servers in advance, thanks to EC2's on-demand and elastic nature.
Diving Deeper into EC2 Instances:
EC2 instances are the virtual servers running on the AWS cloud. Each instance is designed for specific use cases, providing varying combinations of CPU, memory, storage, and networking capacity. Understanding the different instance types is crucial for optimizing performance and cost-effectiveness.
Instance Types: AWS offers a broad spectrum of instance types categorized into families like General Purpose, Compute Optimized, Memory Optimized, Storage Optimized, and GPU instances. Each family is fine-tuned to meet specific application requirements. More information on instance types can be found here.
Choosing the Right Instance: Depending on your application's needs—whether it requires high computational power, ample memory, or extensive storage—you can select the most suitable instance type. We'll explore the characteristics of each family to guide you in making informed decisions.
Launching Your First EC2 Instance:
Now, let's put theory into practice. Follow these steps to launch your first EC2 instance:
1. Access the EC2 Dashboard: Navigate to the AWS Management Console and select the EC2 service.
2. Launch Instance: Click the "Launch Instance" button.
3. Name and tags : Enter the name of the instance. Add tags to categorize and organize your instances.
4. Choose an Amazon Machine Image (AMI): Select an AMI based on your operating system and application requirements.
5. Choose an Instance Type: Pick the instance type that aligns with your application's needs.
6. Key Pair: Create a new key pair if you do not have one.
7. Network Settings: Configure Network. Configure Security Group and define rules for inbound and outbound traffic.
8. Add Storage: Specify the storage requirements for your instance.
9. Review and Launch: Double-check your configurations.
10. Launch Instances: Click "Launch Instances," and voilà! You've just launched your first EC2 instance.
If you go to Instances, you can now see one instance running.
Congratulations on reaching this milestone in your AWS journey! You've not only learned about EC2 basics and its history but also launched your very own EC2 instance.
In the upcoming days, we'll explore more AWS services and build on the foundation we've established today. Stay tuned for more insights and hands-on experiences as we continue our #100DaysOfAWS series.
