Use Cases of CA Systems

Below are the Use Cases of CA Systems

• Financial Transactions: Systems processing financial transactions require strong consistency to ensure accuracy and integrity. High availability is also crucial to maintain operations during peak times.
• E-commerce Platforms: E-commerce sites need consistent product information, pricing, and inventory levels. They also require high availability to handle traffic spikes and ensure seamless shopping experiences.
• Healthcare Systems: Healthcare systems storing patient records and medical data need strong consistency for accuracy and availability to ensure patient care is not interrupted.
• Government Systems: Government systems managing citizen data and public services require strong consistency for data accuracy and high availability for uninterrupted access to critical services.

“CA” stands for Consistency and Availability, in the context of the CAP (Consistency, Availability, Partition tolerance) theorem. A CA System delivers consistency and availability across all the nodes. It can’t do this if there is a partition between any two nodes in the system and therefore does’t support partition tolerance.
