Multi-Tenant vs. Single Tenant – Differentiating Types of Cloud Architecture
In cloud computing, tenancy defines how many customers share physical infrastructure resources like servers. Multi-tenant architecture is like an apartment building—multiple tenants share the same structure but have secure, separate units. Each tenant can customize their own space but cannot alter shared infrastructure. The cloud provider manages system maintenance and updates, offering standardization, lower total cost of ownership (TCO), and a higher return on investment.
In contrast, single-tenant architecture serves only one customer on a dedicated infrastructure, similar to owning a private home. This setup provides full control, visibility, and extensive customization options, including backend access. While it typically costs more, it suits organizations needing strict security, compliance, or specialized configurations. Overall, multi-tenancy emphasizes efficiency and cost savings, whereas single-tenancy prioritizes control and customization Ref- sap blog
What is Cloud Data Centers ?
Ref SAP blog Even though cloud software runs remotely, it still relies on physical servers. Like any other computer, these servers need power to operate.
Imagine a building with rooms and rooms full of computer servers – this is called a data center. Cloud software providers either own and maintain their own data centers, rent space from third-party data center providers, or use a combination of both to ensure their services run smoothly.
