What is the lowest recommended tier of Azure Cache for Redis for production use?

Basic
Standard
Premium
Enterprise

The correct answer is: Standard

The Standard tier of Azure Cache for Redis is the lowest recommended tier for production use due to several advantages it offers over the Basic tier. One of the significant benefits of using the Standard tier is that it supports replication, which provides increased availability by allowing the creation of a primary and a secondary cache instance. This redundancy is essential in production environments where uptime and reliability are critical. Additionally, the Standard tier provides better performance and scalability options compared to the Basic tier. While the Basic tier is suitable for development or testing scenarios, it lacks features like persistence and is limited to a single cache instance with no replication. The Standard tier also supports features such as integrated Redis clustering, which further enhances scalability and distribution of data. In summary, the Standard tier strikes a balance between cost and functionality, making it the most viable option for production scenarios where stability and data redundancy are paramount. This tier meets the needs of enterprise applications, which often require more robust caching solutions, while remaining cost-effective compared to higher tiers like Premium or Enterprise.
