<h2>
2. Key Concepts, Techniques, and Tools
</h2>
<h3>
2.1 Amazon Elastic Compute Cloud (EC2)
</h3>
<p>
EC2 is a core service within the AWS ecosystem that provides on-demand, scalable computing capacity. It allows users to launch virtual servers (instances) in the cloud, offering a wide range of operating systems, instance types, and customizable configurations. EC2 forms the foundation for hosting your website, application, or service.

<h3>
2.2 Amazon Route 53
</h3>
<p>
Route 53 is a highly scalable and reliable Domain Name System (DNS) service provided by AWS. It enables you to manage your domain names, route traffic across different endpoints, and ensure high availability for your web presence. Route 53 plays a critical role in connecting your domain to your EC2 instance, enabling seamless redirection.

<h3>
2.3 Domain Name System (DNS)
</h3>
<p>
DNS is a hierarchical and distributed naming system that translates human-readable domain names (like example.com) into machine-readable IP addresses (like 192.168.1.1). When you enter a domain name into your browser, your computer queries the DNS server to resolve the corresponding IP address, allowing you to access the website or service associated with that domain.
</p>

<h3>
2.4 Record Types
</h3>
<p>
Route 53 supports various record types, each serving a specific purpose. Some of the key record types for domain redirection include:
</p>
<ul>
<li>
<strong>
A Record:
</strong>
Maps a domain name to an IPv4 address.
</li>
<li>
<strong>
AAAA Record:
</strong>
Maps a domain name to an IPv6 address.
</li>
<li>
<strong>
CNAME Record:
</strong>
Creates an alias for another domain name, pointing to the same IP address.
</li>
<li>
<strong>
URL Redirect Record:
</strong>
Redirects a domain name to another URL.
</li>
</ul>
