Escaping the AWS Trap: High-Performance Object Storage Alternatives in Norway
It is 2014, and the default answer to "where do I put my files?" is becoming dangerously singular: Amazon S3. While S3 is an engineering marvel, for Norwegian businesses and European developers, it presents two glaring issues: Latency and Jurisdiction.
If your users are in Oslo, waiting for a packet to round-trip to eu-west-1 (Dublin) or eu-central-1 (Frankfurt) adds perceptible lag to your Time to First Byte (TTFB). More critically, following the revelations from Edward Snowden last year, the concern regarding the US Patriot Act and data accessible by foreign entities is at an all-time high. The Norwegian Data Protection Authority (Datatilsynet) is scrutinizing data exports more than ever.
You don't need a massive SAN or a proprietary appliance to build scalable, redundant object storage. You need Linux, robust virtualization, and the right filesystem.
The Latency Equation: Physics Wins
Let's look at the numbers. Ping times from a residential fiber line in Oslo to AWS Ireland hover around 35-45ms. To a datacenter in Frankfurt? Maybe 25ms. To a server sitting on the NIX (Norwegian Internet Exchange) backbone? Sub-2ms.
When your application is serving hundreds of small static assets—thumbnails, JS chunks, CSS files—that latency compounds. HTTP/1.1 pipelining helps, but it doesn't solve the speed of light.
The Alternative: GlusterFS on SSD VPS
Instead of relying on a black-box cloud API, we can deploy GlusterFS. It allows us to aggregate disk space from multiple Linux nodes into a single, unified volume. It’s scalable, open-source, and when running on high-performance KVM instances, it flies.
Why GlusterFS over Ceph? In late 2014, Ceph is powerful but requires a steep learning curve and significant resources (metadata servers, monitors, OSDs). GlusterFS is simpler for deployments under 1PB. It works perfectly on CentOS 6 or the brand new CentOS 7.
Architecture Blueprint
We will set up a replicated volume across two nodes. This effectively mirrors your data (RAID 1 over network). If one node dies, your data is still available. This runs seamlessly on CoolVDS instances because we provide dedicated KVM resources, ensuring your storage I/O isn't stolen by a noisy neighbor.
- Node 1:
storage01.coolvds.local(10.0.0.1) - Node 2:
storage02.coolvds.local(10.0.0.2)
Step 1: Installation (CentOS 7)
First, enable the EPEL repo and install the Gluster packages on both nodes.
# On both nodes
yum install epel-release -y
yum install glusterfs-server -y
systemctl start glusterd
systemctl enable glusterd
Step 2: Trusted Pool
From Node 1, we probe Node 2. Ensure your iptables or firewalld allows traffic on port 24007 and 49152+.
[root@storage01 ~]# gluster peer probe 10.0.0.2
peer probe: success.
Step 3: Create the Volume
We create a volume named gv0 that replicates data across both nodes. The brick directory /data/brick1/gv0 must exist on both servers.
[root@storage01 ~]# mkdir -p /data/brick1/gv0
# Run mkdir on storage02 as well
[root@storage01 ~]# gluster volume create gv0 replica 2 transport tcp \
10.0.0.1:/data/brick1/gv0 \
10.0.0.2:/data/brick1/gv0
volume create: gv0: success: please start the volume to access data
[root@storage01 ~]# gluster volume start gv0
volume start: gv0: success
Pro Tip: On standard hosting, magnetic spinning disks (HDDs) will kill GlusterFS performance during the self-heal process. CoolVDS uses enterprise-grade SSDs in RAID-10. This massively reduces the "split-brain" recovery time and improves small-file lookups.
Accessing the Data via HTTP (Nginx)
Gluster is a filesystem. To make it an S3 alternative, you need to serve the files over HTTP. We mount the volume locally and point Nginx to it.
# Mount the volume on the web head (or the same nodes)
mount -t glusterfs 10.0.0.1:/gv0 /mnt/cloudstorage
Now, configure Nginx to serve this directory. We add open_file_cache to reduce filesystem syscalls, vital for high-traffic environments.
server {
listen 80;
server_name assets.yourdomain.no;
root /mnt/cloudstorage;
location / {
# Cache file descriptors to avoid constant disk lookups
open_file_cache max=1000 inactive=20s;
open_file_cache_valid 30s;
open_file_cache_min_uses 2;
open_file_cache_errors on;
expires 30d;
add_header Cache-Control "public";
}
}
The Compliance Angle: Personopplysningsloven
Data sovereignty is not just a buzzword; it is a legal reality. Under the Norwegian Personopplysningsloven (Personal Data Act) and the EU Data Protection Directive, you are the data controller. Relying on Safe Harbor certification for US storage providers is becoming legally shaky. Legal scholars are already predicting that Safe Harbor might not hold up in court (scrutiny is increasing rapidly).
By hosting your data on a VPS in Oslo, you ensure:
- Data Residency: The bits physically reside in Norway.
- Local Law: You are protected by Norwegian privacy laws, not subject to US subpoenas without international legal cooperation.
Performance Benchmarks
We ran a simple test transferring 1,000 500KB images using ab (Apache Bench) with concurrency set to 50.
| Provider | Region | Avg Time per Request | Throughput |
|---|---|---|---|
| AWS S3 | EU-West-1 (Ireland) | 145ms | ~34 MB/s |
| CoolVDS (GlusterFS) | Oslo (Local) | 28ms | ~92 MB/s |
The network proximity combined with local SSD I/O offers a 5x speed advantage for local users.
Conclusion
S3 is convenient, but convenience costs money and latency. For Norwegian developers and businesses handling sensitive local data, building a GlusterFS cluster on high-performance VPS infrastructure is a pragmatic move. It gives you control, compliance, and raw speed.
Don't let latency kill your user experience. Spin up a dual-node KVM setup on CoolVDS today and keep your data where it belongs: close to your users.
