A computing system comprising: one or more processors; and memory storing instructions that, when executed by the one or more processors, cause the computing system to perform: receiving, by a central controller engine, a user request to perform one or more operations associated with user data, wherein the user data includes first data and second data; selecting, by the central controller engine based on the user request, a first service provider interface SPI, integrated into a first service, the first SPI being configured to operate on the first data in a first datastore associated with the first service, the first SPI including a common interface component configured to facilitate communication between the central controller engine and the first SPI, and the first SPI including a first service interface component configured based on a uniform access specification; obtaining, by the first service using the first SPI, at least a portion of the first data from the first datastore associated with the first service, the at least a portion of the first data being formatted according to a first service data specification; transforming, by the first SPI based on the uniform access specification, the at least a portion of the first data, thereby generating transformed first data formatted according to the uniform access specification; and providing, by the first service using the first SPI, the transformed first data to a target service; storing, by the central controller engine, a first state of the first service; determining, by the central controller engine, a failure of the first service; and relaunching, by the central controller engine, in response to the determining the failure of the first service, the first service based on the stored first state of the first service. one or more processors;
