Private Cloud vs. Public Cloud: What is the difference?
To understand these in a very simple manner, there are many analogies of private and public clouds such as
- Private cloud is your own house but public cloud as an apartment
- Private cloud watching videos on your local system while public cloud streaming videos online
Is a private cloud cheaper than a public cloud?
Organizations must keep in mind that cost is not the primary driver for adopting or retaining the private clouds. There are often regulatory demands or financial governance that demands data needs to be protected in a certain geography. Some other organizations may demand the lowest possible latency, whilst keeping all the IT resources on a single on-premise data centre also helps in reducing the round-trip network times to an absolute minimum.
The respondents found that the biggest savings and cost efficiencies for private clouds were realised by utilizing automation, capacity planning tools, very flexible licensing arrangements and cost and budgetary management tools.
The needs of every organization are different based on their business models, their traffic and user bases. So based on the needs one should go and opt for either of these services. If someone expects the highest traffic needing higher resources then a private cloud would be a go-to option incurring higher costs as the dedicated resources are being utilised.
What are the advantages and disadvantages of Private Cloud?
Private clouds come with many disadvantages due to their ability to allow autonomy of being ‘owned’ by a single entity. Another important thing is the level of security one can expect in the case of private clouds. On-premise clouds can offer the highest and most superlative degrees of securities and privacy since that enterprise authentication ensure access is granted to only those who send the requests and needs it. There is also a high chance of the lowest latencies in the case of private clouds as all the recourses are co-located in the private data centres.
One of the top drawbacks of private clouds is the incurring higher costs required to maintain, procure, configure and most importantly frequently upgrade the hardware and software for keeping up to date with trends. Also, training expenses can be considered as another major bottom-line that impacts private cloud deployments costs.
