Abstract

Systems and methods are provided for exposing disparate storage systems and technologies to compute instances through a unified file system interface that is agnostic to the underlying storage systems and technologies. A file system namespace service may provide the ability to compose a file system from different storage technologies and systems (e.g., block storage, object storage, etc.). The file system namespace service may also provide the ability to layer different storage services (e.g., by treating local block storage volume as a write back cache, by treating a file system as a read-through cache in front of an object storage service, etc.), and/or the ability to bind virtual files to other compute instances and/or storage systems.

Claims20

Dependent claims

A system comprising:

a host computing device comprising one or more processors and computer-readable memory, wherein the host computing device is configured to execute a compute instance and a namespace service client, and wherein the namespace service client receives file system commands generated by the compute instance using a file system application programming interface (API);
and
a namespace service comprising one or more computing devices, wherein the namespace service is configured to:
receive, from the namespace service client, a namespace service request comprising data representing a file and directory in a namespace associated with the compute instance, wherein the namespace service request is based on a first file system command generated by the compute instance using the file system API;
determine, based at least partly on mapping data associated with the namespace, a network-based storage system mapped to the file, wherein the network-based storage system is to be accessed using a storage system API that is different from the file system API;
and
send, to the namespace service client, a namespace service response comprising data representing the network-based storage system mapped to the file;
and
wherein the host computing device is further configured to:
access data stored on the network-based storage system based at least partly on execution of a storage system operation on the network-based storage system mapped to the file, wherein the storage system operation is different from the first file system command;
and
provide, to the compute instance, access to the data stored on the network-based storage system.

9 more elements

A computer-implemented method comprising:

under control of a computing system comprising memory and one or more computer processors configured to execute specific instructions:
receiving a first request representing a first file system access operation associated with a directory of a file system namespace;
determining, based at least partly on mapping data associated with the file system namespace, a network-based storage system mapped to the directory;
generating a first response to the first request based at least partly on execution of a storage system operation on the network-based storage system mapped to the directory, wherein the storage system operation is different from the first file system access operation;
receiving a second request representing a second file system access operation associated with a file of the file system namespace;
determining, based at least partly on the mapping data, executable code mapped to the file;
and
generating a second response to the second request based at least partly on execution of the executable code mapped to the file, wherein execution of the executable code is different from execution of the second file system access operation.

5 more elements

A system comprising:

computer-readable memory storing executable instructions;
and
one or more computer processors in communication with the computer-readable memory and programmed by the executable instructions to at least:
receive a first request representing a first file system access operation associated with a file of a file system namespace;
determine, based at least partly on mapping data associated with the file system namespace, a network-based storage system mapped to the file;
generate a first response to the first request based at least partly on execution of a storage system operation on the network-based storage system mapped to the file, wherein the storage system operation is different from the first file system access operation;
receive a second request representing a second file system access operation associated with a directory of the file system namespace;
determine, based at least partly on the mapping data, executable code mapped to the directory;
and
generate a second response to the second request based at least partly on execution of the executable code mapped to the directory, wherein execution of the executable code is different from execution of the second file system access operation.
