Answer:
In 2000, a basic internet application cost businesses approximately $150,000 per month. In mid-2016, operating the same application in Amazon's cloud cost approximately $1,000 per month.
Explanation:
The role of cloud services cannot be overemphasized. Providing Infrastructure as a service (IaaS), Platform as a service (PaaS) and Software as a service (SaaS) cost a lot as there were very few cloud service providers and most services were yet to be integrated to the cloud.
But as at 2016, the cost on applications dropped as we have experienced an exponential growth in cloud services and applications, we now have Internet of Things (IoT) and other cloud infrastructure.

Explanation:
Agile testing is software testing that follows the best practices of Agile development. For example, Agile development takes an incremental approach to design. Similarly, Agile testing includes an incremental approach to testing. In this type of software testing, features are tested as they are developed.
Answer:
The solution code is as follows:
- #include <iostream>
- #include <fstream>
- #include <string>
- using namespace std;
- int main()
- {
- ifstream data;
- float number;
- float sum = 0;
-
- data.open("numbers.txt");
-
- while (data >> number) {
- sum = sum + number;
- }
- cout<<sum;
- return 0;
- }
Explanation:
Firstly, we create a ifstream object, <em>data</em> (Line 9). Then we can use the ifstream object to open the "numbers.txt" (Line 13) and use while loop to traverse through the number in the text file line by line (Line 15). White the loop is ongoing the number in each line is read by >> operator in a similar way to cin and then add each read number to sum variable (Line 16).
At last, display the output (Line 18).
