Load balanced clusters for high-traffic sites.

Surf tsunami-sized traffic spikes and service thousands of concurrent transactions per second, without breaking a sweat...

Sample Cluster Configuration A

An entry level cluster is ideal for a single high traffic website with traffic up to five million visitors per month. Features a single load balancer, three NGiNX web servers and a dedicated Varnish Cache server HTTP accelerator.

  • 1 x Load Balancer
  • 3 x Webservers
  • 1 x Database Server
  • 1 x File Server
  • 1 x Varnish Server
  • 1 x Private Switch
  • 1 x Backup Server

Sample Cluster Configuration B

A midrange cluster would feature additional webservers, added database and load balancer redundancy, along with redundant file servers, a private switch, and a dedicated backup server. Perfect for if you want additional network and file isolation courtesy of dedicated hardware.

  • 2 x Load Balancers
  • 6 x Web Servers
  • 2 x Database Servers
  • 2 x File Servers
  • 2 x Varnish Servers
  • 1 x Private Switch
  • 1 x Backup Server

Sample Cluster Configuration C

The most advanced cluster configurations feature their own private network uplink (BGP) and a complete 42U managed rack colocation complete with compute, storage, and networking gear in a self-contained pod. If you have tight security requirements and are looking for the characteristics of Private Cloud Hosting, then this is for you.

  • 2 x Load Balancers
  • 8 x Web Servers
  • 3 x Database Servers
  • 2 x File Servers
  • 2 x Varnish Servers
  • 1 x Private Switch
  • 1 x Backup Server
  • 1 x Splunk Server

a few things included in all clusters...

icon folder cloud

NFS Fault Tolerant Files

Every cluster requires shared storage of some type. Your website & application’s files need a safe home. We like using ZFS because it provides us unlimited file system ‘point in time’ snapshot capabilities.

icon server connection

NGiNX web farm

Redundant webservers read the application’s data files, send queries to the backend Database server(s), and render dynamic pages. Managed Clusters always include at least two or more redundant webservers.

icon server replication

Staging area

Replicate the same configuration of your production environment and test your work before commits. Staging area services are configured identical to Production area services with exception that no provisions will be made for high availability architecture.

icon server heart

Load Balancing

We implement HAproxy clustered load balancing, using hardware heartbeat, to receive and send web traffic to and from your website’s visitors & webservers. Content switching supports dynamic server pool selection, based on any criteria.

icon database replication

Realtime Replication

We are one of the few providers in Europe to offer complete block storage redundancy. If a primary storage system failure, the data stores will immediately “Failover” to the standby SAN without dropping links or timing out.

Varnish Caching

All clusters are setup with Varnish to serve content properly and following your organizations requirements. EuroVPS Priority Support engineers have extensive experience building, maintaining, and configuring Varnish to do exactly what you want.

Support Life Cycle

Fully managed from the physical layer to the software layer.


There isn't a single size for a private cluster that can fit all customers. We take the time to find out exactly what your usage case requires to save you money, and time.


The migration of your web property from any existing hosting to your cluster is managed by us without any interference needed on your part. Emails, blog comments, databases - we migrate it all...


Once migration is completed, a validation session is organised with your team to confirm proper operation of the website. Any hiccups or problems are debuged along the way by us.


We're ready for launch! The final step of this procedure, will be to synchronise files and database tables so that when your migration is completed, you have not lost a single post or comment on your websites.
