A brief definition: On premise means that a company keeps all its IT infrastructure in house and manages it itself (or possibly has it managed by a third party). On cloud means, on the other hand, that the entire IT infrastructure is hosted off-site and someone else is responsible for monitoring and maintaining it.
From this simple distinction, however, come several aspects that must be considered in an on cloud vs. on premise comparison. Indeed, both on premise and on cloud can provide the company with all the IT infrastructure it needs. The choice of one or the other option generally depends on the desired level of security and the preferred cost structure. Indeed, on-premise applications are reliable, secure and allow companies to maintain a level of control that the cloud often cannot provide. However, many CIOs agree that, in addition to their on-premise and legacy systems, they will still need to make use of new cloud and Software as a Service (Saas) applications, via hybrid infrastructures, to achieve their business goals.
On premise pros:
I) Local Hosting: Complete management of the software and applications II) Full control: over software, hardware and data, allowing customisation, security configurations and compliance adherence
AI: On-premise VS Cloud
III) Lack of Internet dependance: On-premises solutions can operate independently of Internet connectivity IV) Capital Expenditure: Organisations typically incur initial costs for the purchase and maintenance of the necessary hardware and software licences V) Privacy: The data remain in the company's devices and are controlled directly by the user
On cloud pros:
I) Accessibility: access from anywhere with an internet connection and any time II) Cost efficiency: Reduces the capital expenditure on hardware and software. Operates on a pay-as-you-go model, where you pay only for the resources you use. III) Data loss: Cloud services often include robust backup and disaster recovery solutions, ensuring data safety and business continuity. IV) Performance: Cloud service providers offer high-performance computing power and infrastructure, often superior to what individual businesses can afford.
