The correct answer is: C. all cloud computing applications combine their resources into pools that can be assigned on demand to users
Cloud computing is the on-demand delivery of IT resources over the Internet with pay-as-you-go pricing. Instead of buying, owning, and maintaining physical data centers and servers, you can access technology services, such as computing power, storage, and databases, on an as-needed basis from a cloud provider like Amazon Web Services (AWS).
Cloud computing offers a number of benefits over traditional IT infrastructure, including:
- Cost savings: Cloud computing can help you save money on IT costs by eliminating the need to purchase and maintain your own hardware and software. You only pay for the resources you use, and you can scale your usage up or down as needed.
- Agility: Cloud computing can help you be more agile by giving you the ability to quickly deploy new applications and services. You can also easily scale your resources up or down to meet changing demand.
- Reliability: Cloud computing providers offer a high level of reliability and uptime. Your data is stored in multiple locations, so it is protected from hardware failures and natural disasters.
- Security: Cloud computing providers offer a high level of security. Your data is encrypted and protected by firewalls and other security measures.
There are three main types of cloud computing:
- Infrastructure as a Service (IaaS): IaaS provides you with access to computing resources, such as servers, storage, and networking. You are responsible for managing your own operating system, applications, and data.
- Platform as a Service (PaaS): PaaS provides you with a platform for developing, testing, and deploying applications. The cloud provider manages the underlying infrastructure, so you can focus on developing your applications.
- Software as a Service (SaaS): SaaS provides you with access to software applications that are hosted on the cloud provider’s infrastructure. You do not need to install or maintain the software, and you can access it from anywhere with an internet connection.
Cloud computing is a powerful tool that can help you save money, be more agile, and improve your security. If you are considering moving to the cloud, it is important to carefully evaluate your needs and choose the right cloud provider for your business.
In the question, option C is the wrong statement. Cloud computing applications do not combine their resources into pools that can be assigned on demand to users. Instead, cloud computing applications are typically deployed on top of a cloud infrastructure that provides a pool of resources that can be assigned on demand to users.
