One File System. Many VMs. Zero Chaos.
How Google Cloud Makes Shared Storage Easy with Filestore
Imagine you’re running multiple virtual machines, and all of them need to read from and write to the same set of files at the same time. Logs, media files, configs, shared assets — everyone needs access.
Block storage won’t cut it here. That’s where Google Cloud Filestore steps in.
What Is Google Cloud Filestore?
Filestore is Google Cloud’s fully managed Network Attached Storage (NAS) service. It provides a shared file system that multiple VMs or containers can access simultaneously.
Think of it like a shared drive in an office:
- One team updates a document
- Everyone else instantly sees the change
No syncing. No copying. No chaos.
Filestore vs Persistent Disk — What’s the Real Difference?
It all comes down to how many things can write at once.
🔹 Persistent Disk (Block Storage)
- Designed for single-writer access
- Best for:
- OS disks
- Databases
- VM-specific storage
🔹 Filestore (File Storage / NAS)
- Designed for multi-writer access
- Best for:
- Shared data across multiple VMs or containers
- Workloads where many apps touch the same files
👉 If multiple machines need the same files at the same time → Filestore wins.
How VMs and Systems Connect to Filestore
Filestore plugs right into Google Cloud networking:
✔ VMs in the same VPC connect directly
✔ Works with Shared VPC setups
✔ On-prem systems can connect using:
- Cloud VPN
- Cloud Interconnect
That makes Filestore a great fit for hybrid cloud environments too.
When Should You Use Filestore?
Filestore shines in scenarios like:
📁 Shared application configuration
🖥️ Content management systems (CMS)
🎥 Media rendering and processing pipelines
🏢 Enterprise apps that need shared state
🚚 Lift-and-shift workloads expecting NFS storage
If your app expects a traditional file system that many servers can use together — Filestore feels right at home.
The Takeaway
Filestore is Google Cloud’s answer to shared, high-performance file storage.
When multiple VMs or applications need concurrent read/write access to the same data, Filestore is the right tool.
Use:
- Persistent Disk → for VM-specific, block-level storage
- Filestore → for shared, multi-writer file systems
Right tool. Right job. No bottlenecks.
