Nginx and Apache Multi-Tenant can be used to minimize cost, effort, and more for enterprises, helping apps work in a shared environment.
In cloud computing, multi-tenancy — in this case, Apache Multi-Tenant and Nginx Multi-Tenant — is a mode of operation of software where multiple independent instances of one or various applications operate in a shared environment.
The software instances are logically isolated but physically integrated. Even if the software instances use the same underlying resources, cloud customers are unaware of each other, and their data is kept separate and secure.
Multi-tenancy is a vital component of cloud computing. Cloud services would be far less practical without this concept. A multi-tenant application can help reduce development and deployment costs to companies that develop applications. This is similar to multiple owners/tenants living in the same building. Even though they live in the same building, they have their own bedroom, kitchen, hall, electricity meter, water taps, etc.
Similarly, customers on the cloud vendors use the same infrastructure and still have their software instance and data separate and secure. Adding a new customer can be simplified using a self sign-up process, and a multi-tenant application has an automated sign-up process along with the required subdomain.
The following explores how enterprises can use Apache Multi-Tenant and Nginx Multi-Tenant to support SaaS applications. This article also highlights how Nginx Multi-Tenant and Apache Multi-Tenant can be achieved along with their respective DNS wildcard records.Why Use Multi-Tenancy in Your Nginx and Apache Configuration?
Nginx Multi-Tenant or Apache can respond to wildcard subdomains (via *), which is excellent for multi-tenant URL-based SaaS applications. A multi-tenant application is one that has a single codebase but supports many clients/tenants. To divide up users/clients/tenants with an application is to use subdomains.
For example, mysaasapplication.com uses subdomains in such a way that each client can have its subdomain where they could log into its application. So customer1 can have something like customer1.mysaasapplication.com and customer2 can have customer2.mysaasapplication.com.
For a better understanding, I suggest you review the differences between single-tenant and multi-tenant SaaS architectures to comprehend how each architecture works.Prerequisite: Set Up Your DNS Subdomains With a Wildcard Record and Dynamically Provision Subdomains for Multi-Tenancy
To access the application, you’ll need to tell the browser the address of the application, and this is taken care of by DNS (Domain Name System). The DNS is the phonebook of the Internet. It is a hierarchical and decentralized naming system for services, computers, or other resources connected to the Internet or a private network.
For a subdomain based SaaS application, we would need a DNS wildcard record.
