 The main goal of this tool is to provide simple HTTP interface for **Ceph's** bare **RADOS** layer.
-**Go-WebRados** is not a replacement for **RadosGW** as is does not have all reach APIs and features of RadosGW(S3, Swift, etc ...), instead it stands for simplicity and performance.

 The ide is to have web accessible storage for millions of relatively small files, which can be accessed from browser directly.

-Running Ceph services on computer which hosts GO-WebRados is not required, it's even better to have a dedicated server or server for running GO-WebRados

 ### **Download and install**

-You can build GO-WebRados from source or download precompiled binaries. If you already have installed Cephs packages and want to make things easy ,

 ### **Large files**

-GO-WebRados will automatically set maximum chunk size to  **OSDMaxObjectSize** of Ceph and split files in accordance to that.
