For when you have outgrown even the most powerful single Dedicated Servers

You have probably realised by now that fast hardware alone is not enough to continuously guarantee fast page load times, even under tsunami sized traffic spikes. If you need to be able to successfully withstand thousands of concurrent transactions per second, you could be a candidate for a Clustered hosting solution.


Add additional webservers, load balancers, and database servers, on the fly as your traffic grows.


All clusters feature fully fault tolerant configurations, which means that no single failure can take you down.


Clustered hosting allows you to achieve sub one-second page load times, even during extreme traffic spikes.

  • Virtual or Bare Metal Options
  • All server roles are 100% fault-tolerant
  • Completely Managed Solution
  • Capable of servicing millions of users
  • Premier Support Tier
  • Built Using Opensource Software

Sample Cluster Configurations

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

Features and Benefits

Just like a tailor fit suit, many measurements must be taken before a cluster is built. There is not a single size for a managed cluster that can fit all customers. We take the time to find out exactly what your usage case requires to save you time and money.

nginx webserver icon
Redundant Webservers

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.

redundant database server icon
Redundant Database Servers

Every dynamic website has a database or two which is critical to it’s proper operation. Whether your application requires MySQL or Microsoft SQL Server, we can build the proper solution to exactly match your requirements.

staging area icon
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.

nfs fault tolerant files icon
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.

Block Storage 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.

haproxy load balancer icon small
Load Balancers

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.

log management icon small
Nagios Log Analyzer

Get centralized log aggregation and search engine installation exclusively for your organization’s needs. All logs across your entire hosting arrangement are aggregated into one user simple to use user interface, and this is available to you via an SSL secured web portal.

varnish caching icon small
Caching and Acceleration Engine

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

Clusters are fully managed, from the physical hardware layer, all the way to the software layer.

Step 1


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. Performance metrics from any existing configuration are very helpful to properly size IOPS and Database server capacity, as well as NFS server scaling
Step 2


The migration of your web property from any existing hosting to your Private Cluster, is managed by us. We manage everything in-house, without any interference needed on your part. We migrate it all, emails, blog comments, all of it.
Step 3


Once migration is completed, a validation session is organised with your team. We work side by side with your developers to confirm proper operation of the website, databases, cron jobs, emails, forms, caching, and backup systems. We debug any problems or hiccups encountered along the way. For example, web server change to NGINX, databases change to InnoDB, or Varnish caching things it shouldn't etc.
Step 4


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 Joomla, WordPress, or Drupal websites.
Step 5


After the implementation is complete, monitoring is established on your server, and on your application. We use a combination of Paessler PRTG, Nagios, and MRTG monitoring systems to observe the real-time status of your infrastructure. We also regularly use New Relic to monitor your application webstack on a PHP and Database level.

What our managed hosting customers are saying

Trusted by thousands of small, medium and large businesses since 2004

My average page load used to be 12 seconds before migrating to EuroVPS. Now it has dropped to 2 seconds without cache. EuroVPS assisted me with everything. From migrating to my new VPS, to optimizing it for high performance. Giuseppe Barbiero Founder
At my previous host ticket response times were over 24 hours which was not acceptable for a news site like ours. At EuroVPS, most problems are solved in less than 30 minutes. Tunc Satiroglu Founder
Before moving to a load balanced clustered solution, I had problems every day. My server just couldn't cope with the growing traffic. Big thanks to the EuroVPS team for setting up the solution in under 48 hours! Sevan Bomar Founder
As a big rock band from south-east Europe with 400k fan base on Facebook and over 40 years of existence our production standards are really high so as our online communication standards. Which is why we chose EuroVPS. Ivan Kozlik Webmaster
EuroVPS has proven to be a provider that delivers good support, assistance and quality. I hope our partnership will be there for many more years, but we will have to see how it it all evolves the upcoming years. Eelco Alosery Founder
EuroVPS seem to have "doing things properly" encoded in their DNA. I've been a customer of EuroVPS since 2010 and they set the standard for what every hosting provider should do; quietly and constantly provide hosting. I hope to be with them for at another 5 years.
