Businesses have always been in two minds about which one’s better for them, moving their data to the cloud or keeping it on premise. While both have their own advantages.
here are some of the major parameters that they should consider while choosing to move or stay out:
● Budget available:
Budget is a major factor while choosing a data management service. For instance, for a big Hadoop cluster, you will need people to manage it and handle costs. Operating a large data center will cost millions of dollars each year. A public cloud works well with a pay-as-you-go system that guarantees payment only for the equipment used. Those are charged on an hourly basis. Thanks to its cost-effectiveness, and hence ideal for small companies.
● Scalability:
A public cloud can be scaled within minutes and it needs only a few steps to scale up thanks to the easy availability of hosts. It can be carried out automatically and scaled up and down as needed. This flexibility in storage is beneficial, especially if you are dealing with unpredictable data streams that must be stored and processed. With an on-premise private cloud, scaling up often requires extra hardware that can be expensive and time-consuming.
● Compliance and security:
In a conventional data center, security must be managed by the company. There are multiple aspects such as access control and video surveillance that one must take care of. If you are dealing with private and sensitive data, it might not be safe to store them in the public cloud from a compliance perspective. When strict control over data is needed, a public cloud with servers in different locations is not the ideal solution. With a private cloud solution, organizations can actively restrict access internally and externally.
● Performance requirements:
A private cloud within a company’s firewall will lead to a faster access to data. On the other hand, public clouds are reliant on the transfer rate of the ISP. With large volumes of data, this could be an issue as fiber optic internet is not widely available yet. Additionally, a private cloud can be customized in terms of storage performance, hardware performance, and network performance.
● Organization type: The type of your organization and the vertical that you operate in will determine what is permissible and beneficial for storing data. If you must deal with government data, it will be imperative for you to store the data on-premise and not in a public cloud. If technology is your core competency, it is worthwhile to use the on-premise cloud, otherwise it is wiser to outsource that part of your company to a host.
● Commitment to third parties:
There are no long-term contracts with a public cloud, especially with the pay-as-you-go model. After the subscription expires, there is no compulsion to stay with them. With a private cloud you would need hardware which is often expensive. In contrast, with a public cloud you have limited control over how your data is handled and how the hardware is monitored. This is carried out by a third party.
● Big data maturity:
The level of big data maturity in your company also impacts the choice between a private or public cloud. If you are starting off with a Proof of Concept, installing a complete Hadoop cluster will be of no use. Using a public cloud will be a lot less expensive and more effective. However, if you are already mature, you may conclude that Big Data operated in-house is a lot easier and offers greater advantage than public cloud.
Based on your condition, requirements, the size of your company, the budget allocated, and the kind of data stored and analyzed you must choose the best solution. However, the best option might change over time, so it is imperative to use the feedback from your customers, employees, IT systems, and organization to determine what’s best.
