Designing a Three-Tier Web Architecture

Design scalable three-tier web architectures on AWS

Three-tier architecture separates an application into distinct presentation, application, and data layers, helping teams improve scalability, resilience, and maintainability.

On this course, you’ll apply core AWS architecture principles to the design of a complete three-tier web application.

You’ll explore how networking, compute, load balancing, storage, and database services can be combined to support each layer of the architecture while considering availability, performance, security, and future growth.

Structure applications across three architectural tiers

Examine the role of the presentation, application, and data layers and how separating responsibilities can support more resilient cloud applications.

You’ll consider how traffic and data move between tiers and where different AWS services fit within the overall design.

Design for availability and changing demand

Explore how services such as Amazon EC2, load balancing, and scaling capabilities can help applications respond to fluctuating traffic and reduce the impact of individual component failures.

You’ll also consider how networking choices influence accessibility and resilience.

Connect applications to reliable data services

Consider how database and storage requirements shape the data tier, including how services such as Amazon RDS can support application workloads.

You’ll evaluate design choices around performance, availability, connectivity, and data protection.

By the end, you’ll understand how the individual layers of a three-tier application come together on AWS and be better equipped to assess and design scalable web architectures for real-world requirements.
