# The demise of the filesystem and multi level service architecture

## TL;DR

This paper discusses the shift from traditional filesystems to object stores in astronomy data centers, highlighting benefits for scalability and challenges for legacy systems.

## Contribution

It analyzes the implications of adopting object stores over POSIX filesystems in astronomy data centers, emphasizing architectural and software reuse opportunities.

## Key findings

- Object stores enable better scalability for Big Data in astronomy.
- Legacy systems face integration challenges with object store architectures.
- Transitioning to object stores offers increased portability and software reuse.

## Abstract

Many astronomy data centres still work on filesystems. Industry has moved on; current practice in computing infrastructure is to achieve Big Data scalability using object stores rather than POSIX file systems. This presents us with opportunities for portability and reuse of software underlying processing and archive systems but it also causes problems for legacy implementations in current data centers.
