Introduction to types of IT Deployments
With increasing adoption of cloud solutions, many organizations want to understand the difference between on premises IT and cloud and what is the best option to choose for their businesses. As cloud services are seen more attractive as they enable businesses to combine with management IT service and transfer the cost and responsibility of running on premises hardware and software onto a specialized service provider who can manage all hassles and costs which otherwise burden organizations on rising IT management costs such as software upgrades, hardware upgrades, patching, maintenance etc.
Today we look more in detail about two important terminologies: On Premise IT deployments and cloud deployments which are a crucial choice for any organization planning to run its operations with high availability, low costs and no overheads of maintenance. This article will give insight into the major differences between the two, its purpose for which they are deployed and use cases.
What is On-Premise deployment?
In an on-premise deployment all services are running , managed and maintained within the organization on their own hardware and servers. Some businesses may choose to do this due to security and compliance reasons as well.
On premises environments have costs associated with managing and maintaining all the solutions in house. An on-premises setup requires in-house server hardware, software licenses, integration capabilities, and IT employees on hand to support and manage potential issues as they arise. This may not include the cost the company is incurred when something breaks or is non-functional.
Benefits of On-Premise deployments
- Data, hardware, software everything is yours so you have better control
- Lower total cost of ownership as compared to cloud system
- No external dependencies like internet connectivity etc.
What is Cloud deployment?
Cloud computing offers organizations the facility to host everything with a third party provider. This allows companies to pay-as-you-go and effectively scale up or scale down infrastructure requirements depending on overall usage , user requirements and company growth.
A cloud-based server hosts a virtual server to host company applications, data offsite. There are no capital expenses , data is backed up regularly, and companies pay only for resources they utilize. Cloud allows us to connect with customers, business partners and other businesses beyond geographical/ boundaries and also facilitates instant provisioning as everything is already configured using a VM image. Any new software integrated in the environment is ready to use immediately once subscription is in place.
Benefits of Cloud deployment
- Anywhere , anytime access
- Affordable as there are no up-front costs, and your pay operating expenses
- Not to worry about maintenance of hardware, software etc
- Cloud data centres have world class security measures which are otherwise may not be affordable for a business
- Greater flexibility and scalability
- Lowers energy costs as you don’t pay to power on premises servers or maintain environment
Comparison Table: On-Premise vs Cloud
Below table summarizes the difference between the two types of deployments:
|Deployment||Resources are deployed in house and within an organization IT infrastructure and they are responsible for maintaining it and it also requires dedicated IT staff which looks after infrastructure||Resources are hosted on cloud computing environment; resources are hosted on the premises of service provider.|
Cloud environment gives instant provisioning, as the software is pre-configured by cloud service provider
|Costs||Ongoing costs to be borne by organizations of server hardware, software, maintenance costs etc and it is costlier than cloud environments||Pay for use of resources which they actually use with none of maintenance or upkeep costs . Cloud provider is responsible for cost of purchasing the hardware and maintenance of infrastructure|
|Control||All data , hardware, software is in full control of internal IT teams.||Depending on cloud deployment model choose – hardware, software and applications may be in control of service provider|
|Security||Companies dealing with sensitive data such as banking , financials, government departments maintain certain level of security and privacy which on premises environment provides||Though best of security controls are implemented however your data is hosted on a third-party provider so there are rising concerns on data security on cloud|
|Compliance||Companies falling under certain regulations such as HIPPA, PCI DSS etc would prefer to have on premises deployments need to know where their data is at all times||Cloud providers required to be compliant with all regulatory norms within their industry and sensitive data must be secured and privacy should be ensured|
|Accessibility||Accessibility is restricted to device on which software is originally installed||Accessibility is for broad range of devices via mobile and web applications|

Majority of businesses, small or large in size are adopting cloud-based deployments because of cost, agility, and ease of use. On-premise solutions are a worthwhile option for companies with serious security concerns, but even many of these companies choose to move to cloud.
