The high availability infrastructure of a private cloud is comprised of hosting in a world-class datacenter, a managed hosting solution with high-availability firewalls, load balancing, enterprise grade hardware, disk-to-disk-to-tape continuous data protection, advanced monitoring and patching. This combination of redundancy and managed services provides your Private Cloud with the backbone necessary to guarantee your applications are always available.
As the director of a software division for a small consulting firm, I am absolutely dependent upon a secure and reliable host for our websites. Not only does PayPerCloud.com provide just that environment, but my proactive account manager delivers regular check-ins that allow us to ward off potential issues before they develop. If our websites and related infrastructure go down, our sales process grinds to a halt; with PayPerCloud.com they simply do not. Working with PayPerCloud.com allows me to focus on the internal personnel and production aspects of our business because I know that our marketing machine is in good hands with PayPerCloud.com.
Biddle Consulting Group, Inc.
Pay Per Cloud builds the best custom Private Clouds for businesses. A Private Cloud is a dedicated cluster of highly available, scalable, secure and redundant web servers deployed in a Hyper-V Cloud Architecture. Compared to the traditional approach of purchasing, provisioning and managing the architecture, Pay Per Cloud's Private Cloud solution is an all inclusive solution which includes provision, setup, perpetual licensing, monitoring and complete management of the cluster thereby guaranteeing enhanced security, improved back-up options, experienced technical support for maintenance, brand-new name-brand equipment, and zero downtime.
3 x Host Servers (Windows R2 Datacenter Edition)
5TB SAN Storage Server (Centralized Shared Storage)
Unlimited Virtual Servers (running any combination of OS)
Pay Per Cloud can also build a VMware based private cloud architecture with multiple ESX host servers dedicated and configured to your needs along with centralized SAN storage. Pay Per Cloud is able to offer the full spectrum of enterprise features such as High Availability (HA), Fault Tolerance (FT), Distributed Resource Scheduling (DRS) and VMotion.
Our Private Cloud Architecture offers 100% uptime SLAs with 'High Availability (HA)' and 'Fault Tolerance' features. Both these features have the ability to offer continuous availability for hosted virtual machines in case of a host failure.
High Availability provides a base level of protection for hosted VMs by restarting them in the event of a host failure. Fault Tolerance provides a higher level of availability, allowing users to protect any VM from a host failure with no loss of data, transactions, or connections. This is done by ensuring that the state of the Primary and Secondary VM is identical at any point in the instruction execution of the virtual machine. With failover, there is no data loss and network connections are maintained. After a failover occurs, a new Secondary VM is automatically re-spawned and redundancy is re-established. The entire process is transparent and fully automated.
As illustrated in the diagram, we use SAN storage for a Private Cloud Architecture which is shared among all your virtual servers. It is essential to have SAN storage if you wish to implement High Availability as that requires the VMs to be stored on shared storage available to all the hosts. Even though there are a few other storage options available, we recommend SAN Storage as it is capable of meeting the IO requirements of all of the Virtual Machines.
