Difference between on-premise and cloud

What is the difference between on-premise and cloud?

What is the difference between on-premise and cloud? The primary difference between cloud and on-premise computing is the location in which your applications and data are stored.
  • On-premise: In the case of the on-premise computer, all data is stored locally. Your company is the owner and maintainer of its servers, hardware and software. You are in complete control of your security and data, but this also means you are responsible for maintaining the equipment, maintaining it, and making sure that everything runs smoothly.

  • Cloud: Cloud computing is where your information and applications reside on servers that are owned and controlled by a third party. They are accessible via the internet. This relieves you of the hassle of maintaining physical infrastructure, and allows for more flexibility and greater scalability when your requirements evolve.

Here are the main differences:

On-Premise and Cloud Use Cases and Industry Applications

What Is On-premise?

On-premises means what you call the IT technology and the software that is located in an office or physical location of the organization and hosted on site. On-premise means that the software runs on hardware owned by the organization and situated in their physical facilities of the business generally in the organization’s personal data center. On-premise can also be referred to as”on-premises” or “on-prem”.

On-premise computing means that the IT personnel has greater control over the hardware of the server and data configuration as well as security and management since they have access to all the information in physical form. Your internal staff are able to access data and important information, but no third parties have access to it remotely.

On-premise Key Characteristics

  • Control: Businesses have total control over their equipment and software.
  • Security: Information is saved locally, which is considered to be more secure by certain companies.
  • Customization: Systems are completely customized to meet particular requirements.
  • Cost: A high initial capital investment for buying software and hardware in addition to regular maintenance expenses.

On-Premise Advantages and Disadvantages


  • Security: You are in total control over your data along with physical measures to protect it. This is essential for extremely sensitive data.
  • Customization: You are able to tailor your software and hardware to meet your requirements.
  • No reliance on internet: The on-premise systems work without internet access.


  • High upfront cost: The cost of buying and maintaining all hardware and software by yourself.
  • Limited scalability: Scaling up resources can be complicated and costly.
  • IT burden: Your  IT staff is accountable for updates, maintenance, and troubleshooting.

What is Cloud Computing?

Cloud computing differs from traditional software in a crucial way. An organization hosts everything internally within an on-premise system however, in a cloud-based environment the third-party hosting provider manages everything for you. This lets companies pay as needed and to effectively expand or reduce their capacity based on usage patterns as well as the needs of the users and the expansion of the company.

Cloud-based servers use technologies that are virtual to house applications offsite for a company. There is no cost for capital and data backups can be set frequently, and companies are only responsible to use the services they utilize. For companies that are planning an aggressive expansion plan globally cloud computing offers more appeal as it enables users to connect with their customers and partners as well as other companies anywhere, with little effort.

Cloud Key Characteristics

  • Scalability: Resource capacity can be scaled down in response to the need, which allows for flexibility.
  • Cost: It operates with a pay-as you-go model, eliminating the need for massive upfront investment.
  • Accessibility: Data and services can be accessed from any place via an internet connection.
  • Maintenance: The cloud provider is accountable for the maintenance of the infrastructure, which includes updates along with security updates.
  • Innovation: Many providers provide the latest technologies and services that can be quickly taken up.

Cloud Key Characteristics


  • Cost-effective: Usually, you pay less upfront costs, and you only pay for the services you actually use.
  • Scalability: You can easily adapt resources upwards or downwards depending on your requirements.
  • Accessibility: Access information and applications from any location that has an internet connection.
  • Reduced IT burden: Cloud providers handle updates and maintenance.


  • Security: You depend on the security measures of your cloud provider but they may not be appropriate for every data.
  • Internet dependence: A reliable internet connection is essential for accessing cloud resources.
  • Vendor lock-in:  Switching clouds providers is a challenge and costly.

Key Considerations When Choosing Between On-Premise And Cloud

Choosing between cloud and on-premise computing is a matter of careful consideration of a variety of aspects that impact your company’s operations security, budget, and. Here’s a list of the most important factors to consider:

Security and Compliance:

  • Data Sensitivity: What hygienic is the information that you’ll store? If it’s extremely confidential (e.g. health records, financial information) it might be better to store it on premises. This could give you more security over physical security as well as access.
  • Regulatory Requirements: Are there regulations in the industry which regulate the storage of data and access? Make sure your solution conforms to the relevant standards of compliance.

Cost and Scalability:

  • Upfront Costs: On-premise solutions require a substantial upfront investment in the hardware, software and IT personnel. Cloud-based services generally come with lower upfront costs due to a pay-as you-go model.
