Generate a series of (instruction, response) pairs that are similar in context and structure to the example provided below. Each pair should consist of a concise instruction followed by an appropriate, detailed response. The instruction should pose a clear task or question, while the response should provide a comprehensive answer or solution that could be understood by someone with a basic understanding of the subject.

Example pair: 
Instruction: Can you please summarize the aspects and workings of big data mentioned in the article in a few lines?

Use information only from the following part of the article:

What Is Big Data? 
Big data refers to the large, diverse sets of information that grow at ever-increasing rates. It encompasses the volume of information, the velocity or speed at which it is created and collected, and the variety or scope of the data points being covered (known as the "three v's" of big data). Big data often comes from data mining and arrives in multiple formats. 

How Big Data Works 
Big data can be categorized as unstructured or structured. Structured data consists of information already managed by the organization in databases and spreadsheets; it is frequently numeric in nature. Unstructured data is information that is unorganized and does not fall into a predetermined model or format. It includes data gathered from social media sources, which help institutions gather information on customer needs. Big data can be collected from publicly shared comments on social networks and websites, voluntarily gathered from personal electronics and apps, through questionnaires, product purchases, and electronic check-ins. The presence of sensors and other inputs in smart devices allows for data to be gathered across a broad spectrum of situations and circumstances. Big data is most often stored in computer databases and is analyzed using software specifically designed to handle large, complex data sets. Many software-as-a-service (SaaS) companies specialize in managing this type of complex data.
Response: Big data refers to massive, rapidly growing sets of diverse information from multiple sources. It includes social media, personal electronics, and shopping activity, among others. Structured data is numeric and already managed by organizations in databases and spreadsheets, while unstructured data is not organized and includes data from social media sources. Ultimately, big data is stored in computer databases and analyzed using specialized software designed to handle large, complex data sets.

Your task is to generate more pairs that maintain this level of clarity and detail. The topic is Summarization. Write a long text of instruction by yourself, then summarize the given instruction in a response. Ensure that the responses are informative and accurate, suitable for an educational context. 

Store the generated pairs in valid JSON format, with each pair as an object within an array. Each object should have two key-value pairs: "instruction" and "response". For instance: 

{"contents": [{"instruction": "text", "response": "text"}, {"instruction": "text", "response": "text"}, ...]} 

Remember to maintain consistency in the format and ensure the generated pairs are diverse and cover a broad range of subjects. You must return the response in the asked format and you must not add any additional text in your response.

Can you provide a brief explanation of the concept of cloud computing based on this description: Cloud computing is the delivery of computing services—including servers, storage, databases, networking, software, analytics, and intelligence—over the Internet ('the cloud') to offer faster innovation, flexible resources, and economies of scale. Companies typically pay only for cloud services they use, helping lower operating costs, run infrastructure more efficiently, and scale as business needs change?

Cloud computing involves delivering various computing services over the internet, including storage, databases, and networking. It allows for faster innovation, flexible resource allocation, and cost-efficiency, with companies only paying for the services they use.
