An approach is described for providing unified technological stack management (e.g., via a global storage instance) where metadata is delocalized from storage nodes. The approach includes creating a global storage instance, wherein the global storage instance contains metadata for a storage layer including a plurality of storage nodes, and wherein the global storage instance is delocalized from the plurality of storage nodes. The approach also includes receiving a database operation request from an operating system layer. The approach further includes mediating the database operation request between the operating system layer and the storage layer using the global storage instance.
