Businesses have several options for managing their IT resources, some of which include on-premise, cloud, and hybrid computing. You need to weigh the pros and cons of each to find out which one is the optimal choice for your business.
Most people are familiar with on-premise computing. This is the traditional method of computing where software is installed on computers at the site where the company is located.
Advantages of On-Premise Computing
- Full control and ownership over IT resources
Disadvantages of On-Premise Computing
- Steep upfront expenses may be incurred for configuration and installation of on-premise hardware and software
- On-premise IT systems can be managed only by visiting the site
- High level of technical expertise is necessary
- Dedicated full-time IT staff is necessary to manage the on-premises computing resources
- Scalability problems can arise with a sudden increase in operations
- Greater risk of downtime
Cloud computing allows users to enjoy IT services without the need to actively manage them. Therefore, you can enjoy the benefits of networking, hardware resources, software, and databases without having to spend time and energy on their management. The cloud service provider is responsible for managing IT resources at your disposal.
Advantages of Cloud Computing
- Users can access their data and applications from any location and at any time they like
- Expenditure is subscription-based (payment is according to resources consumed)
- Scale-up and down at a time of your choosing
- Software management, modifications, and updates are managed remotely
- A guarantee provided for very high service uptime
- Maintenance and integration issues handled remotely
- High-security thanks to service provider expertise
- No need for users to hire dedicated full-time IT staff
- Users can save a lot of costs since they do not have to purchase IT resources or hire a full-time IT staff
Disadvantages of Cloud Computing
- Users may have to cede some control over IT resources
- Data is not stored on-site
Hybrid Cloud Computing
Hybrid cloud computing is the amalgamation of on-premise and cloud computing. Hybrid computing aims to provide the best of both worlds while mitigating potential disadvantages that arise when these paradigms are deployed exclusively.
Hybrid Cloud Computing Advantages
- High scalability and flexibility means that users can expand operations since IT resources are available
- You can put dev/test workloads on the cloud to scale capacity according to demand
- Since you can scale down easily you only pay for what is needed
- Thanks to the service provider’s investment and expertise in the network, users can enjoy accessibility, availability, and reliability
- Allows users to gain the best from public and private clouds
Hybrid Cloud Computing Disadvantages
- Can be expensive due to the high expenditure of private clouds
- Certain regulatory requirements may exist that prohibit offsite storage of data
Some of the leading service providers of hybrid cloud computing are Microsoft, Amazon, Google, Hewlett Packard, IBM, Verizon, Fujitsu, Cisco, and Hitachi among many others.
