Imagine you work for a small to medium-sized company with a public facing web application deployed on-premises. Your servers are aging and running at near-capacity. Rather than invest further in hardware, you're going to migrate to Azure. You want the benefits of hosting in the cloud but minimize downtime and leverage the existing skills of your team. Further, the application layered and deployed on an N-tier architecture. You want to ensure that you're able to scale, manage, and secure your application now and in the future.
In this module, you'll learn what N-tier (or multitier) architecture is, when to use it, and what are both the benefits and drawbacks of this architectural style.
By understanding what makes up an N-tier architecture and how to optimize it, you can make the right decisions when selecting an architecture for new applications, or improve deployments of existing applications.
In this module you will:
- Identify the features, limitations, and considerations of the N-tier architecture style
- Identify use cases for when an N-tier architecture is appropriate
- Deploy a sample N-tier architecture
- Identify methods and resources to improve your N-tier architecture
