Public Cloud or Private Cloud – Which Model is Better When?
Comparison of Private and Public Clouds can be made from a different perspective and may vary according to the type of application and security requirements. The following are the two main parameters of the model spread to considered.
Governance – In the private deployment model, there is better control over the data (and data security), whereas in the case of public models, Cloud Service Providers are responsible for many activities related to securing infrastructure and data. Speed and agility: models of public and private Cloud deployment both have the ability to balance resources and provide minimal turnaround time.
Risk Management : Private Cloud deployments are usually behind the organization’s firewall, and so better with risk control vs. Clouds. General Compliance: Private Cloud reduces the security and privacy issues associated with workload set goes beyond the firewall by providing an efficient and full control over resources.
Culture : Private Cloud deployment is better aligned with the culture of command-and-control and prospective corporate organization IT. Familiar environment can easily manage.
Cloud Economics : Private Cloud improving existing infrastructure investments and it is much more effective for long-running workloads. It turns out “money an hour” compound too quickly because of the price you pay includes all their costs, and in addition, some healthy margins even for compute-intensive applications very Hadoop style, dissemination Public Cloud can offer cost advantage.
CapEx : Public Cloud have better rates of resource utilization: a Private Cloud, organizations still develop and maintain resources such as computing, storage, and network to meet the increasing demand in various business units. There are costs associated with the maintenance of resources, planning for redundancy to prevent data loss and disasters, which involve additional experts to oversee all operations in the Resources premise.
Adequate : public cloud infrastructure costs to support new projects and for private Clouds, organization need to get the resources to meet the requirements of planned projects that could pop up.
Elasticity : public clouds offer greater elasticity and gives a bit limited resources are available for use during this Private Cloud deployments are not case.
Economies Scale: has the economy of scale of public clouds over Cloud counterparts. Public larger than they have dramatically changed performance expectations for IT, but there are industries where securities transaction latency Public Cloud will lead to acceptable levels of service, loss of revenue, etc. This concern has caught the attention of IT is a strategic decision leadership.
It to build your own Cloud stakeholders need to think comprehensively and simply. It is the need of the hour IT organizations need to enable self-service, and the provider of on-demand infrastructure, platforms, and applications for their internal business units. Speed and agility, not cost reduction, private cloud implementation journey.
