Question

why do we need cloud computing

Answer 1

Simply put, cloud computing iscomputing based on the internet. Where in the past, people would run applications or programs from software downloaded on a physical computer or server in their building,cloud computing allows people access to the same kinds of applications through the internet.

Answer 2

Only five items but how significantly important they are!

1. Costs reduction as compared to purchasing and maintaining bare metal servers in conventional data centers. With the cloud, you pay only for the computational resources consumed, with no upfront expenses.

2. Easier data backup and recovery. All of the leading CSP’s, be it AWS or GCP, Azure or IBM Cloud provide convenient backup/restore functionality, and the user has only to tick a checkbox to make it work.

3. Infrastructure scalability. Cloud service providers are able to scale the resources up and down at your request, so you do not pay for the unused resources and you can always have as much RAM, traffic or CPU power as needed.

4. Convenient of monitoring. There are multiple built-in and third-party monitoring tools available to the cloud users. This enables them to always be aware of the current state of events with their software and services.

5. The basis for Big Data. Of course, the business can leverage on-prem dedicated servers and computational resources for Big Data analytics. However, these resources will remain idle between the analysis rounds, or some complex configuration will be required to administer them appropriately.
