Question

A developer is about to launch an EC2 instance in the AWS Management Console. Which configuration option must they choose first before they start the Amazon EC2 launch wizard?

A. The Amazon Machine Image (AMI)
B. The key pair
C. The virtual private cloud (VPC)
D. The Region

Answer

D. The Region

Explanation

Before a user goes to launch an EC2 instance in the AWS Management Console, they should consider the Region that it will go in. The Region that they are viewing their Amazon EC2 dashboard from is the Region that their instance will be launched into. The Region cannot be configured from the Amazon EC2 launch wizard. The VPC, key pair, and AMI will all be congured in the Amazon EC2 launch wizard.

Before launching an Amazon EC2 instance through the AWS Management Console, the first configuration option a developer must choose is the Region. The AWS Region determines the geographical location where the EC2 instance will be hosted and run.

Here’s why selecting the Region is crucial:

  1. Availability: Different AWS services and resources are available in specific Regions. By choosing the appropriate Region, developers ensure that the required services and features are accessible for their EC2 instance.
  2. Latency: The proximity of the Region to the users or target audience affects the latency and response time of the application running on the EC2 instance. Selecting a Region closer to the users helps minimize latency and improve performance.
  3. Compliance: Some industries and applications may have specific data residency or compliance requirements that dictate where the data should be stored and processed. Choosing the right Region ensures compliance with such regulations.
  4. Pricing: The cost of running EC2 instances and other AWS resources can vary across different Regions. Developers should consider the pricing differences and select a Region that aligns with their budget and cost optimization strategies.

Only after selecting the desired Region can developers proceed with other configuration options in the EC2 launch wizard, such as choosing the Amazon Machine Image (AMI), specifying the instance type, configuring security groups, and selecting the key pair for secure access to the instance.

In summary, the Region is the first and most important configuration option developers must choose before launching an EC2 instance in the AWS Management Console. It determines the geographical location, availability of services, latency, compliance, and pricing aspects of the EC2 instance.
