Introduction

Welcome to another installment of my "Understanding Cloud Series," where we explore various concepts related to cloud computing. Amazon Web Services (AWS) is a leading cloud computing platform that provides a wide range of services for businesses and developers to build and manage scalable and reliable applications. In this blog, we will explore some fundamental aspects of AWS architecture and key services, including Virtual Private Cloud (VPC), Wavelength, CloudFront, AWS Amplify, AWS Backup, Disaster Recovery Solution (DRS), and Databases. We will provide step-by-step guides and examples to help you understand and leverage these services effectively.

Virtual Private Cloud (VPC)

VPC is a crucial component of AWS architecture that allows you to create a private, isolated network within the AWS cloud. This enables you to launch AWS resources, such as Amazon EC2 instances and RDS databases, in a secure and controlled environment.

Note: Please refer my previous blog on VPC for more theory! 🔗 A Deep Dive into AWS VPC

Let's go through a step-by-step guide on setting up a basic VPC:

Step 1: Log in to your AWS Management Console.

Step 2: Navigate to the VPC dashboard and click on "Create VPC."

Step 3: Configure the VPC settings, including the IPv4 CIDR block and DNS settings.

Step 4: Create subnets within the VPC for different availability zones.

Step 5: Set up an Internet Gateway to allow internet access for instances in public subnets.

Step 6: Create a route table for the public subnet and associate it with the Internet Gateway.

Step 7: Launch an EC2 instance in the public subnet and test internet connectivity.

AWS Wavelength

AWS Wavelength is a service that brings AWS services to the edge of the 5G networks of telecommunication providers. It aims to reduce latency and improve application performance for mobile and IoT applications that require real-time processing and low-latency communication.

Wavelength integrates AWS infrastructure with 5G networks, placing AWS compute and storage resources in the proximity of 5G base stations. This enables developers to deploy applications and services closer to end-users and devices, reducing the time it takes for data to travel back and forth between the cloud and devices.

By leveraging Wavelength, developers can provide better user experiences for latency-sensitive applications, such as online gaming, augmented reality, virtual reality, video streaming, and real-time analytics.

Let's explore a simple example of using AWS Wavelength:

Example: Deploying an application with AWS Wavelength

Step 1: Identify the supported AWS Wavelength zones available in your region.

Step 2: Create a new VPC and subnet in an AWS Wavelength zone.

Step 3: Deploy your application on AWS resources (e.g., EC2 instances) within the Wavelength subnet.

Step 4: Test the application's reduced latency by accessing it from a 5G-enabled device in the same Wavelength zone.

Amazon CloudFront

Amazon CloudFront is a Content Delivery Network (CDN) service offered by AWS. It accelerates the delivery of content, such as web pages, images, videos, and other static assets, to end-users by caching the content at edge locations worldwide.

Key features of CloudFront include:

Edge Locations: CloudFront has a network of edge locations globally, strategically placed in different geographic locations to serve cached content with low latency.
Distribution: A CloudFront distribution is a configuration that defines the origin server (e.g., an S3 bucket, an EC2 instance, or a custom origin) and cache behaviors for content.
Cache-Control: CloudFront allows users to set Time-to-Live (TTL) values, determining how long content should be cached at edge locations.
HTTPS Support: CloudFront supports secure HTTPS connections, allowing users to deliver content securely over SSL/TLS.
Signed URLs and Cookies: CloudFront supports signed URLs and signed cookies for content protection and access control.

AWS architecture is designed to provide high availability, scalability, and fault tolerance to ensure the best possible performance and reliability for applications and services hosted on the platform.

AWS Architecture is built on a foundation of Regions and Availability Zones. Regions are geographical locations where AWS has multiple data centers (Availability Zones) to ensure redundancy and fault tolerance. Each Availability Zone is an isolated data center with its own power, cooling, and networking infrastructure. By deploying resources across multiple Availability Zones within a Region, users can achieve high availability and fault tolerance.

AWS provides a wide range of services, including computing, storage, databases, networking, analytics, machine learning, security, and more.
