To run a business you will need to make use of different computing workloads. But to maximize resources uses for such workloads you would need to invest in a wide range of hard drives, memory chips and computer components. While such a range may seem fit to cater to the existing needs it will not be enough to cope when the business shrinks or expands. Moreover, the whole effort is going to be very costly to maintain.
So, many on-site enterprises face this issue of being overburdened with a huge range of equipment which may eventually not even meet their business needs. When these businesses switched to the cloud, the private cloud was expected to resolve their needs. This is because the private cloud has been designed for addressing needs of businesses facing such a predicament. It is the most cost-efficient model for demarcating the workload space within fixed costs. The private cloud has not been founded inside the public cloud hosting model. Rather, according to many industry analysts, it is perhaps the antithesis of a public cloud model. It restricts the expansion of public clouds by placing the virtual machines in a smaller and fixed environment.
Workload is a generic term which implies an independent set of services or processes. The independent nature is the defining factor when one considers the modern infrastructural technologies. So, it is necessary to analyze whether it is possible to pick this service up from one server and then run it on some other server. Some examples of such computing workloads are database, batch, backups, website, mobile application etc. The batch workload covers huge volumes of data and this may be run at scheduled intervals. Batches may include audits, data reconciliation and system syncing. Such workloads will depend on data access, predetermined scripts and memory pool. So long as the original system gets access to the data involved, the scripts may be picked up and then moved onto a new server.
The primary reason why enterprises find more success while using the private cloud hosting is because it is more of an evolution of the dedicated server and not the public cloud. The need for dedicated servers grew as the demands for dedicated IP addresses, root access and dedicated resource pool also increased. Earlier, when companies signed up for shared hosting plans, they could not get root access or static IP addresses. So, businesses which had smaller workloads yet needed root access or dedicated IP were forced to upgrade to a dedicated hosting plan. These were situations which led to the emergence of the VPS environment and eventually, the cloud.
On the other side, users of dedicated hosting had many workloads they had to deploy and these were placed on one server. This might have been cost-effective and reduced complexities, but at the same time it triggered performance issues. There were computing and storage bottlenecks leading to poor performance, along with business continuity problems and security issues. So, the solution for this problem was to buy more servers. This would automatically escalate costs but would successfully eliminate performance problems. The cloud was expected to be the perfect answer to all these issues but it was definitely not the most cost-friendly solution even when you compared it to buying multiple dedicated servers.
Cloud prices rely on overselling hardware. for instance if you were to take ten virtual machines from cloud hosts and compare their costs to costs of an equal amount of hardware which you can buy from a dedicated host, you will find the indian cloud hosting prices to be very steep. By applying the philosophy of the cloud to dedicated hosting one would get the power to streamline the existing server configurations and ensure that each workload gets the quantity of resources it needs. This will mean server consolidation and higher flexibility for resource provisioning that is just right for the workloads. So, it will give the DevOps and system administrators the power to automate resource provisioning across multiple servers according to predefined criteria. This is indeed a game changer.
With a private cloud, the user can therefore take up a dedicated hosting environment and then split it into as many virtual machines as he deems fit to handle existing workloads. So, he will not have to pay licensing costs for every VM or overheads. The public cloud in comparison cannot be defined well. The private cloud offers an organizer for your resources. There are businesses which need the flexibility to scale up and shrink in a matter of seconds. On the whole, almost every business needs a cost-effective way for organizing their workloads. Such a solution should be able to offer an optimal balance of resources so as to ensure that the engine runs at the highest efficiency.
