This is a Google PHP SDK that provides access to the Google Cloud Spanner API. The API is a scalable, enterprise-grade, globally-distributed, relational database service that is built for the cloud. It allows you to combine the benefits of relational database structure with non-relational horizontal scale. Google Cloud helps developers build with cloud tools and infrastructure, applications, maps and devices.
As the amount of processing power that can be affordably invoked via the cloud continues to increase, applications that were once thought too impractical to build are suddenly quite feasible. A good example of that is AppStream, a new service that Amazon is beta testing that allows graphically and resource-intensive applications to be extended out to any number of devices that previously would not have had the processing capabilities to run them.
It used to be that integrating data across different applications required an unnatural act involving complicated pieces of middleware. In recent times, accomplishing that act has become easier thanks to lighter-weight middleware based on standard Web services and RESTful APIs. But even still, accomplishing that task still requires the skills of a developer. In contrast, the next revolution in data integration is going to be characterized by business users integrating data across applications on their own at will.
