How to Launch an AWS-EC2 Instance

Amazon Elastic Compute Cloud (Amazon EC2) is a web service provided by Amazon Web Services (AWS) that allows you to run virtual machines, known as instances, in the cloud. EC2 instances serve a wide range of purposes and can be used for various computing tasks.

Here are some common use cases for EC2 instances:

  • Web Hosting: You can deploy web servers on EC2 instances to host websites, web applications, and web services. This is one of the most common use cases.
  • Application Hosting: Run your applications in the cloud on EC2 instances. This includes custom software, APIs, and server-based applications.
  • Development and Testing: EC2 instances are often used as development and testing environments. You can spin up instances with specific configurations to develop, test, and debug software.
  • Data Storage: Store data on EC2 instances using attached EBS (Elastic Block Store) volumes. This data can be databases, files, or other forms of storage.
  • Big Data Processing: EC2 instances are used for big data processing tasks, such as running Hadoop clusters or Spark jobs.
  • Machine Learning and AI: Train machine learning models and run AI workloads on EC2 instances. AWS also offers specialized instance types for machine learning.
  • Content Delivery: Use EC2 instances as origin servers for content delivery networks (CDNs) to deliver content, such as images and videos, to users around the world.
  • Desktop Virtualization: EC2 instances can be used to provide remote desktops and virtual desktop infrastructure (VDI) for users.
  • High-Performance Computing (HPC): Run scientific simulations, financial modeling, and other compute-intensive tasks on EC2 instances, particularly with GPU-equipped instances.
  • Container Orchestration: Deploy containerized applications using services like Amazon Elastic Kubernetes Service (EKS) or Amazon Elastic Container Service (ECS) on EC2 instances.
  • Security and Compliance: EC2 instances can be configured to meet specific security and compliance requirements, making them suitable for hosting sensitive data or workloads.
  • Backup and Disaster Recovery: EC2 instances can be used as part of a backup and disaster recovery strategy. You can create AMIs (Amazon Machine Images) of your instances for quick recovery in case of failures.
  • IoT and Edge Computing: EC2 instances can be deployed at the edge of the network to process data from IoT devices and perform local computation.
  • Application Load Balancing: Use EC2 instances behind a load balancer to distribute traffic and ensure high availability and fault tolerance for your applications.
  • Hybrid Cloud: EC2 instances can be integrated into a hybrid cloud setup, connecting on-premises infrastructure to the cloud.
  • Game Server Hosting: EC2 instances can host game servers for online multiplayer games.

It's essential to choose the right EC2 instance type, configuration, and pricing model (on-demand, reserved, or spot instances) to match your specific workload and budget. AWS provides a wide range of instance types optimized for various use cases, including compute-optimized, memory-optimized, storage-optimized, GPU-based, and more.

Prerequisites:
  • AWS Account
Step 1: Create an AWS Account (or/and) Login to your Management Console.

Then Navigate to the EC2 dashboard.

Step 2: Launch a new EC2 Instance.

Assign it a name.

Step 3: Operative System selection

Here you can select any operative system of your choice, just keep in mind that this article was created to support How to deploy Nextjs application on AWS-EC2 (Nginx, Ubuntu, SSL certificates)?, meaning that it only cover the setup on Ubuntu 22.04 and a different choice would require different commands and packages.

Step 4: Select your micro requirements

By default it provides a Free tier “t2.micro”. In case your application needs a faster processing you can select from a variety of options.

Step 5: Key Pair

Create a new key pair or use a previously created key that you have access to.

Step 6: Create a new security group to avoid disruption while following the next tutorial.

You may select an existing security group, but since you are following this article I would like to suggest you to create a new one.

Note: Make sure you marked the checkbox for SSH, HTTPS and HTTP.

Step 7:

There is no need to modify your instance storage unless your needs are different. Congrats! Now you can Launch your Instance.
