Describe cloud service requirements.
CLOUD SERVICE REQUIREMENTS
Cloud computing consists of hardware and software resources made available on the Internet as managed by third-party services. Cloud services requirements typically provide access to advanced software applications and high-end networks of server computers. Service providers create cloud computing systems to serve common business or research needs.
Examples of cloud computing services include:
1. Virtual IT. It configures and utilizes remote third-party servers as extensions to a company's local IT network.
2. Software. They utilize commercial software applications or develop and remotely host custom-built applications.
3. Network storage. The backup or archive data across the Internet to a provider without needing to know the physical location of storage.
Cloud computing systems in general are designed for scalability to support large numbers of customers and surges in demand. Service providers are responsible for installing and maintaining core technology within the cloud. Some customers prefer this model because it limits their manageability burden. However, customers cannot directly control system stability in this model and are highly dependent on the provider instead.
Cloud computing systems are normally designed to closely track all system resources, which enables providers to charge customers according to the resources each consumes. Some customers will prefer this so-called metered billing approach to save money, while others will prefer a flat-rate subscription to ensure predictable monthly or yearly costs. Using a cloud computing environment generally requires you to send data over the Internet and store it on a third-party system. The privacy and security risks associated with this model must be weighed against alternatives.
