Getting Started with AWS EC2

Creating an AWS account

The first step in getting started with AWS EC2 is to create an AWS account. You can do this by visiting the AWS website and clicking on the “Create an AWS Account” button. Follow the instructions to create your account, including providing payment information and verifying your identity.

Launching an EC2 instance

Once you have an AWS account, you can launch an EC2 instance. To do this, you will need to navigate to the EC2 console and click on the “Launch Instance” button. From there, you can select the operating system and instance type that you want, configure your security settings, and launch your instance.

Connecting to an EC2 instance

After you have launched your EC2 instance, you will need to connect to it to begin using it. The method for connecting to your instance will depend on the operating system you have selected. For Linux instances, you can use SSH to connect to your instance. For Windows instances, you can use Remote Desktop to connect. You will need to have your instance’s public IP address and the appropriate login credentials to connect.

EC2 (Elastic Compute Cloud) Instance Types are optimized for different workloads and applications. Here are the four main types of EC2 instances:

  1. General Purpose Instances: These instances are designed to handle a wide range of workloads, from small to large applications, and offer a balance of CPU, memory, and network resources. They are a good choice for applications that don’t have specific resource requirements.
  2. Compute Optimized Instances: These instances are designed for compute-intensive workloads that require high CPU performance. They are ideal for applications that require a lot of processing power, such as high-performance computing, batch processing, and scientific modeling.
  3. Memory Optimized Instances: These instances are designed for memory-intensive workloads that require high memory performance, such as in-memory databases, real-time big data processing, and high-performance computing. They offer a large amount of RAM and high memory bandwidth.
  4. Storage Optimized Instances: These instances are designed for storage-intensive workloads that require high storage performance, such as data warehousing, NoSQL databases, and log processing. They offer a high amount of local storage and high disk throughput.

Security Groups:
AWS Security Groups act as virtual firewalls for your instances in the cloud. They control inbound and outbound traffic, allowing you to specify which traffic should be allowed and which should be blocked. Security Groups are associated with an instance or a network interface and can be modified at any time based on your needs. They are essential for securing your AWS infrastructure.

Virtual Private Cloud (VPC):
VPC is a logically isolated virtual network within the AWS cloud. It allows you to customize your network configuration, including IP address range, subnets, routing tables, and network gateways. With VPC, you can create a private network that is completely isolated from the public internet or connect your VPC to your on-premises network using a VPN connection. VPC provides a secure and scalable environment for running your applications and services.

Elastic IP Addresses:
Elastic IP addresses are static, public IP addresses that can be associated with your AWS resources, such as EC2 instances, NAT gateways, and network interfaces. They are designed for dynamic cloud computing environments where instances can be started and stopped frequently. Elastic IP addresses allow you to maintain a consistent IP address for your resources, even if they are stopped and restarted. This makes it easier to maintain your network configuration and avoid any disruption to your applications or services.

AWS offers a range of storage options that can meet the diverse needs of businesses with varying levels of data storage requirements. Here are some of the most commonly used storage options:

  1. Amazon Elastic Block Store (EBS)
    Amazon Elastic Block Store (EBS) provides persistent block-level storage volumes for use with Amazon EC2 instances. EBS volumes are highly available, reliable, and scalable. They can be used for a variety of use cases such as database storage, boot volumes, and data warehousing.
  2. Amazon Elastic File System (EFS)
    Amazon Elastic File System (EFS) is a fully-managed, scalable, and highly available file storage system that can be accessed from multiple EC2 instances at the same time. It is ideal for workloads that require shared access to files, such as web serving, content management, and big data analytics.
  3. Amazon Simple Storage Service (S3)
    Amazon Simple Storage Service (S3) is a fully-managed object storage service that offers industry-leading scalability, data availability, security, and performance. It can be used to store and retrieve any amount of data from anywhere on the web. S3 is commonly used for backup and archival, static website hosting, and big data analytics.

Scaling and Load Balancing

Auto Scaling

Auto Scaling is a feature provided by AWS that allows you to automatically adjust the number of instances in your application based on the demand. With Auto Scaling, you can ensure that your application can handle sudden spikes in traffic and also minimize the cost by reducing the number of instances during periods of low demand. Auto Scaling uses different metrics such as CPU utilization, network traffic, and application load to determine when to add or remove instances.

Elastic Load Balancing

Elastic Load Balancing is a service provided by AWS that allows you to distribute incoming traffic across multiple instances in different availability zones. By using Elastic Load Balancing, you can improve the availability and scalability of your application. Elastic Load Balancing can automatically detect unhealthy instances and route the traffic to healthy instances. There are three types of Elastic Load Balancers – Application Load Balancer, Network Load Balancer, and Classic Load Balancer – each with its own set of features and use cases.

Monitoring, Logging and Troubleshooting

Amazon CloudWatch

Amazon CloudWatch is a monitoring and observability service that helps you collect and track metrics, collect and monitor log files, and set alarms. It provides you with actionable insights to monitor your applications, respond to system-wide performance changes, optimize resource utilization, and get a unified view of operational health.

With Amazon CloudWatch, you can monitor AWS resources such as EC2 instances, RDS instances, and Elastic Load Balancers, as well as custom metrics generated by your applications and services. You can also monitor system-wide metrics, such as CPU utilization, network traffic, and disk usage.

AWS CloudTrail

AWS CloudTrail is a service that enables governance, compliance, operational auditing, and risk auditing of your AWS account. It provides you with a record of actions taken by a user, role, or an AWS service in your account. This includes actions taken through the AWS Management Console, AWS CLI, and AWS SDKs and APIs.

AWS CloudTrail logs information such as the identity of the API caller, the time of the API call, the source IP address of the API caller, the request parameters, and the response elements returned by the AWS service. This information can be used to troubleshoot operational issues, investigate security incidents, and ensure compliance with regulatory requirements.

AWS Config

AWS Config is a service that enables you to assess, audit, and evaluate the configurations of your AWS resources. It provides you with a detailed inventory of your AWS resources, as well as the relationships between them. This includes information such as resource types, resource IDs, tags, and configuration details.

AWS Config also enables you to monitor and record changes to the configurations of your AWS resources over time. This includes changes made through the AWS Management Console, AWS CLI, and AWS SDKs and APIs. You can use this information to troubleshoot operational issues, identify security vulnerabilities, and ensure compliance with regulatory requirements.


On-Demand Instances

On-Demand Instances refer to the pay-as-you-go pricing model in which you pay for the compute capacity by the hour or per second, depending on the instance type. This pricing model is suitable for workloads that are short-term, unpredictable, or have a high rate of change. You can launch, stop, and terminate instances as per your needs, and you are only charged for the time you use the instances.

Reserved Instances

Reserved Instances (RIs) provide a significant discount on the hourly charge for the instance type. In this pricing model, you commit to use an instance for a one- or three-year term, and in return, you receive a discounted price for the instance. The discount varies based on the instance type, region, and the payment option you choose (upfront, partial upfront, or no upfront). RIs are suitable for workloads that have predictable usage patterns, have a long-term commitment, and require a specific instance type.

Spot Instances

Spot Instances allow you to bid on unused EC2 capacity in the AWS cloud marketplace. The hourly price of the instance fluctuates based on the supply and demand of the capacity. You can launch Spot Instances at a significantly lower price than On-Demand Instances, but AWS may terminate your instance if the capacity is needed by a higher bidder. Spot Instances are suitable for workloads that are flexible in terms of start and end time and can tolerate interruptions. They are ideal for batch processing, data analysis, and other non-critical workloads.
