Cloud Self Healing + Auto Failover Server
CLOUD POWERED! ( Redundancy + Data Storage Failover + SAN + Hypervisor)

Cloud Technology provide single points of failure are eliminated with CloudServer.pk from not only the software, but hardware levels as well.

We can deploy, scale, or migrate entire servers in just a few moments, which is much faster than a traditional Web Hosting environment.

No longer are Web Hosting "servers" tied to a physical machine.

When you have an account with CloudServer.pk, your account is instantly, and constantly replicated across multiple machines and multiple storage locations. If your website is running on a physical server that crashes, it is instantly restarted on one that available.

You may have read about massive cloud failures with other companies, however many of those were due to a single point of failure on the underlying engine. Each one of our private clouds run off of an underlying engine, or distribution server which manages the applications running on each cloud and physical server. In CloudServer.pk, we replicate this engine in real time across multiple physical machines so in the event of a failure, the backup engine is automatically and instantly restarted on another server.

Our custom implementation provides the benefits a cloud provides, but environments are also separated into smaller, scalable applications similar to that of a traditional Shared Web Hosting provider.

We like to keep it simple and provide you with the same Web Hosting terms that you are already used to, and use the same billing methods as before, but provide the benefits that cloud has to offer.

What is the Cloud Server Redundancy?

HP operates by having redundant servers which are then used to provide service when system components fail. Normally, if a server with a particular application crashes, the application will be unavailable until someone fixes the crashed server. HP clustering remedies this situation by detecting hardware/software faults, and immediately restarting the application on another server without requiring administrative intervention, a process known as failover.

What is the Cloud Data Storage Failover?

A storage area network (SAN) is a dedicated storage network that provides access to consolidated, block level storage with multiple failover disk drives. Our SANs are used to make disk storage arrays, accessible to our HP servers so that the devices appear as locally attached to the operating system and has many redundancy data arrays so if one or multiple drives fails another data drive picks up in a few seconds while the bad drive(s) are replaced.

Enterprise Class Cloud Architecture
We have multiple hypervisors providing the virtualization and powering VMs with CPU and Memory, a centralized Storage Area Network, VM backup servers, and an R1Soft Backup Cluster all powered by a central OnApp control appliance.
We have broken the Cloud down in easy to understand terms on our Cloud Architecture.

The Hypervisors
You can search Google for a definition of a hypervisor and be overwhelmed with a lot of technical jargon. Basically a hypervisor provides the virtualization in a cloud but no data is actually stored in a hypervisor. The hypervisor provides the CPU power and memory to power a cloud server and if a hypervisor fails, cloud servers bound to it will be automatically rebooted onto other hypervisors thus providing the auto-failover.

OnApp Control Server
OnApp is the program that powers the whole cloud setup. It works from a centralized server that monitors the hypervisors and provides the auto-failover in case a hypervisor fails. The cloud will also operate as normal even if the control panel fails or taken down for maintenance. Cloud server snapshots are also stored on this multi-terabyte RAID protected central server.

Redundant. Scalable. Self Healing.
Redundant:: The CloudServer.pk VPS Cloud was engineered with multiple layers of redundancy to prevent any single point of failure (SPOF) as well as for disaster recovery purposes.

At the disk level, our SAN clusters consist of an array of Enterprise-class disk drives in a RAID10 configuration which would prevent a faulty drive from failing the entire SAN cluster.

At the SAN level, our Primary SAN cluster is backed up to a Backup SAN cluster. In the unlikely scenario where our Primary SAN fails, we also have a Failover SAN cluster that can take over while the Primary SAN is being fixed.


Scalable:: One of the key benefits of the Cloud is the ability to add resources on the fly. We can add more CPU and RAM to the cloud by adding additional hypervisors. Likewise, if more disk space is required, we can add more disks to our SAN cluster. Since each individual hypervisors are stateless and utilize the same SAN cluster, we can scale the cloud up very easily.

Likewise, virtual machines (VMs) can also be resized up or down on the fly. This can be done by allocating or deallocating virtualized CPU, RAM, and SAN disk resources.

Self Healing:: This is the ability for virtual machines in the Cloud to failover to another hypervisor automatically.


The health of all hypervisors are constantly monitored. If a failed hypervisor is detected, all virtual machines of the failed hypervisor will be migrated to another suitable hypervisor in the cloud so that those VMs can continue to run while the failed hypervisor is taken offline for repairs.
