This includes the ability to develop APIs for ad hoc data access, specialized services for developing reports, and integration with artificial intelligence and machine learning algorithms for more sophisticated advanced analytics. Some organizations are comfortable with effectively lifting and shifting their existing vendor-based data warehouse platform from on premises to a similarly configured cloud-based platform. Other organizations use data warehouse migration as an opportunity to revisit the underlying architecture and consider the potential benefits of abandoning their existing vendor selections for cloud-based reporting and analytics services. These forward- thinking organizations can leverage the types of resources and services CSPs provide to radically improve their analytics environments. For example, many organizations have a variety of reporting and business intelligence (BI) tools for building and producing reports. Although these tools can be implemented using a cloud data warehouse as their back end, the cloud offers alternatives. CSPs provide cloud-based services specifically engineered to replicate the same reporting and analysis techniques employed by users with traditional tools. Because cloud hosts want to encourage their customers to increase their use of cloud resources, they have developed services supporting all aspects of the analytics/BI environment. For example, cloud hosts provide tools for data profiling, metadata management, and data management across a variety of levels of storage, including in-memory data provision, block storage using solid-state disk (SSD) storage, more traditional disk storage, and even archival storage. These different layers of a storage hierarchy can be leveraged to reduce costs by balancing accessibility and access latency against higher or lower costs of the different storage paradigms.
