National Cloud Database Day is celebrated annually on June 1 to raise awareness and appreciation for cloud databases and the professionals who maintain them, underscoring their critical role in powering modern applications across various industries such as transportation, retail, and banking. With cloud databases now comprising over 49% of the market, the day highlights the importance of these technologies in enabling digital business growth, mobile device integration, and agile development, effectively rendering legacy databases obsolete. Couchbase's database-as-a-service, Capella, exemplifies the benefits of cloud databases by offering flexibility, scalability, and performance for enterprise applications, as demonstrated by companies like Quantic and Lotum, which have successfully utilized Capella to streamline operations and enhance user experiences. The day's observance encourages participation through social media engagement and industry events, promoting the continued celebration and recognition of cloud databases' impact on technology and business.
