ESDS – Private Cloud Setup Architecture

The Private Cloud offers a more secure and expandable alternative to public solutions for businesses looking to migrate their existing server infrastructure over to an environment that is more practical and manageable. Although shared cloud solutions can offer up to 100% up time and instant expandability, for large enterprises that already have substantial infrastructures that have been developed around servers that are hosted on-site and with web hosting companies, the shared cloud can be rather limiting because mass migration isn’t supported in most cases; the solution to this is the private cloud because the instead of sharing the cloud cluster with multiple users, a business will have its own cluster that it can add to as it wishes.


Every server in the cloud will be used to contribute resources to the overall pool from which your virtual machines will be created. Depending on what your specific requirements are of the private cloud, the number of servers that you will be using is going to differentiate from that of other users; if you ever reach a point where the volume of virtual machines in your cloud is beginning to impact on resource availability then you can create additional capacity by adding extra servers. Your virtual machines will be formed of the same resources that you will find related to an ordinary dedicated server, including RAM, CPU and disk space; each virtual machine will have resources allocated to it from across the cloud to guarantee stability and system stability. When calculating your requirements for the Private Cloud, you should identify the precise resources that are going to be needed based on your existing server configurations.


Similarly to the shared cloud, you will still only be paying for what you require when using the private cloud because you will have the option to choose the resources that you will need to get started with your new private cloud configuration. As your use of the private cloud increases you can always add additional storage through SANs (Storage Area Networks) and other resources with the use of extra servers, but only when you require it.


More often than not you will want to migrate existing dedicated servers into your new private cloud because one of the main reasons for considering a private cloud is so that savings can be made. There are several different methods that can be used to migrate a physical server into a virtual environment, such as:

You can create the virtual machine from scratch and install the OS layer, from which you can install the applications and configure them to pull the necessary data from the remote server

Alternatively, you can create an image of the hard disk of the server that you wish to migrate and then setup a new virtual machine in the private cloud using this disk image – the VM should be configured with resources similar to those of the existing physical server so that the applications and services that are part of the image can run as efficiently as they do currently.


The infrastructure of the private cloud solutions needs to be managed from one central location so that every server in the cluster can communicate with one another so that all requests are processed properly and that data is kept in constant synchronization. The private cloud services offered by ESDS will be based around our own eNlight cloud platform, a product that we have developed in-house to meet the high standards of service and reliability purveyed by ESDS. The eNlight platform will run across every server that forms the private cloud so that the state of each server can be monitored from one web-based control panel; from here you can also add additional servers to your cluster and create the all-important virtual machines in our private cloud.


The cost of a private cloud will depend on what your individual demands are because the amount of hardware that forms your cloud will be the deciding factor as to how much you’ll have to pay. A private cloud solution from ESDS will be one of the more affordable and cost effective options when compared to what our competitors have to offer because we operate out of our own data center in Nashik, India and offer our own cloud hosting platform – eNlight.
