Designing scalable and resilient systems


One of the main features of the Microsoft Azure technology is scalability. By carefully designing our system, we can build it to manually or automatically scale (elastic scaling) to meet our business requirements as the business grows, or to cope with peaks in system load. Databases and storages can also be designed to be distributed across databases and storage partitions, allowing large volumes of data to scale while maintaining performance.

Note

Scale out means increasing computing capacity by increasing the number of compute instances in a system (for websites and cloud services, this would mean increasing the number of virtual machines). Scale up means increasing the computational resources of a compute instance (for websites and cloud services, this would mean more CPU/memory/disk allocation for a virtual machine instance).

By breaking down large systems into smaller, decoupled subsystems, which interact with each other in an asynchronous fault...
