Before delving into the debate of private versus public cloud, let us first skim through the basic definition of a cloud. The online available resources that could be used for data storage and computing purposes are known as cloud services. The word cloud has gained attention in recent years as data storage centers or data servers. Cloud services could be used by people over the internet from anywhere around the globe. Companies could potentially save dollars by moving to cloud solutions, since they are cost-effective and provide ample space and resources for company data servers, networking, and databases. The agility of cloud computing is also a big reason for companies to shift to this data storage solution.
Types of Cloud Computing
The next big concept to understand is the type of cloud. It could either be a private or a public cloud. The difference between the two is knotted around two basic questions,
Private Cloud: As the name itself suggests, a single user or a group of related users own a server, that is said to be a private cloud. Cloud computing services are associated with a particular organization and are not accessed by the general public. The private cloud is limited to a specific business form and is a dedicated server. A secured firewall limits its use to a specific organization or related tenants. It could either be on-site or off-site. The private nature of the cloud allows customized usage, more adaptability, and separate control and security. On the downside, being exclusive to a single organization or business renders private cloud computing high in cost. They are cost-intensive.
Public Cloud: On the other hand, a public cloud as understood by its name, is a freely available space server on the internet. It is accessible to the general public. Google Cloud, Azure, and Amazon are known as public cloud platforms. The servers in the public cloud could be used by several unrelated tenants or users. A huge advantage of public cloud managed services is cost-effectiveness or low cost, that takes away the pressures of huge investments and capital. On the dark side, being available to the public and several users, the customization is limited and so is the control.
Public Vs Private Cloud Computing
Let us go in detail over some of the prominent differences between private and public cloud,
|Public Cloud||Private Cloud|
|Business requirements are met through affordable cloud solutions, but low on customization and security||Business requirements are fulfilled through high cost with a high degree of customization and high security|
|Pay as you go, and subscription base cost system which is affordable by most users, usage-based cost||Large IT cost, overhead is high and implementation of services is cost-intensive|
|Offers less to absolutely no control over the physical servers because of widespread use||Offers greater control over the physical servers because of limited and customized use|
|Offers services which are shared over the network, with low-performance levels||Fully private services with high-performance levels from dedicated servers|
|Infrastructure has shared usage policy with multi-tenant or users||No sharing policy with the fully private network used by related tenants|
Depending on your company, your type of business, users, business needs, and database, you reassess your cloud operations best suites for your company. Some industries like medical, or government require private cloud but the management decides which computing solution to implement based on the capital investment decisions.
