TheG7 Cluster in Detail

Our Promise ...



TheG7 Linux Cluster is built not only to prevent service outages, but also to provide the full capacity of all cluster servers during standard operation. This leads to a reduction of the response times even in the face of increasing load due to an increasing amount of web site visitors or complex applications.

Protection against hardware failure

Even the best technology will fail at some point, but at Jolis, we've got you covered. Our unique clustered approach ensures that should hardware fail, healthy servers simply close ranks and share the load.

Extra capacity when you need it

Load Balanced clustered approach results in compute capacity that stretches across our whole network. So instead of being limited by the power of one single server, your limits stretch as high as our entire infrastructure. If you websites see a huge spike in demand in an instant, we’ll be ready for it.

Compute resource groups

Compute resource groups are assigned and configured specifically to deliver maximum performance for specific tasks. Each resource group dynamically grows as demand increases.

As much storage as you’ll ever need

Just like our computer resources, storage is clustered which means you’ve got access to all the storage you’ll ever need. If we need more, we simply add more resources to the cluster.

All packages on the Cloud cluster include the below hardware resources and software modules.

Minimum baseline capacity
CPU Capacity Minimum 80 CPU Cores
RAM Capacity Minimum 320 GB RAM
HDD Capacity Over 30 Terabytes of storage
All packages include
PHP 5.3.x, 5.4.x   IonCube Loader   Auto-scaling capacity  
MySQL 5.1   OpenSSL   Load balanced  
Zend Optimiser   APC/Memcache   Daily backups  

Reliability - high availability of your site

In the event of a software or hardware related failure on one server, any tasks of the machine are automatically taken over by another server in the cluster. Your web presence therefore will remain available with no interruption of service and the defective server can be looked after without time pressure. All vital services required for this important feature are already preconfigured in a G7 Linux Cluster. If a machine fails, the rest of the cluster will take over its tasks automatically, independently and instantly.

Load balancing - cost effective utilization of resources

In almost all usage scenarios, the capacities of all existing servers can be utilized simultaneously during regular operation. That way, the performance of the servers does not need to lay idle or in hot stand-by until a failure occurs, but instead can be actively used to reduce response times or to increase the number of potential users accessing at the same time. This objective is achieved by a preconfigured load balancing mechanism. The mechanism works on the IP layer and therefore can be used for many applications in a comfortable and easy way. The load balancing is provided by multiple machines so that the load balancing itself does not represent a single point of failure.

Data security - don't take a risk

Data loss is a horrible and dreaded scenario for every large web application. Data which might have been gathered over years could be extinguished in the blink of an eye. Even by using highest quality hard disks, one is always vulnerable to mechanical failures. A corrupted file system is another circumstance which might lead to data loss. The G7 Linux Cluster was developed with a focus on data safety in mind. Your data is not only mirrored on one single server, but rather replicated on multiple systems. Even the complete breakdown of one server would not have any influence on your data.
