There are three main service models of cloud computing – Infrastructure as a Service (IaaS), Platform as a Service (PaaS) and Software as a Service (SaaS). There are clear differences between the three and what they can offer a business in terms of storage and resource pooling, but they can also interact with each other to form one comprehensive model of cloud computing.
aaS (Infrastructure as Service)
This is the most common service model of cloud computing as it offers the fundamental infrastructure of virtual servers, network, operating systems and data storage drives. It allows for the flexibility, reliability and scalability that many businesses seek with the cloud, and removes the need for hardware in the office. This makes it ideal for small and medium sized organisations looking for a cost-effective IT solution to support business growth. IaaS is a fully outsourced pay-for-use service and is available as a public, private or hybrid infrastructure.
PaaS (Platform-as-a-Service)
This is where cloud computing providers deploy the infrastructure and software framework, but businesses can develop and run their own applications. Web applications can be created quickly and easily via PaaS, and the service is flexible and robust enough to support them. PaaS solutions are scalable and ideal for business environments where multiple developers are working on a single project. It is also handy for situations where an existing data source (such as CRM tool) needs to be leveraged.
SaaS (Software as a Service)
This cloud computing solution involves the deployment of software over the internet to variousbusinesses who pay via subscription or a pay-per-use model. It is a valuable tool for CRM and for applications that need a lot of web or mobile access – such as mobile sales management software. SaaS is managed from a central location so businesses don’t have to worry about maintaining it themselves, and is ideal for short-term projects.
It kind of depends on the intended language, but I can see the following mistakes:
- lines not terminated with a semicolon (but not all languages require this)
- while statement missing parenthesis, ie., while (num1 <= num2), also not required in all languages
- statements below the while statement must be grouped by curly braces
- num1+5 should be num1=num1+5 or num1 += 5
Output will be:
10
15
20
25
30
Answer:
void print_popcorn_time(int bag_ounces){
if(bag_ounces < 3){
cout<<"Too small"<<endl;
}else if(bag_ounces > 10){
cout<<"Too large"<<endl;
}else{
cout<<(6 * bag_ounces)<<"seconds"<<endl;
}
}
Explanation:
The function is the block of the statement which performs the special task.
For checking the condition in the program, the if-else statement is used.
It can check the condition one or two but if we want to check the more than two different conditions then the continuous if-else statement is used.
syntax of continuous if else:
if(condition){
statement;
}else if(condition)
statement;
}else{
statement;
}
In the question, there are three conditions;
1. bag_ounces is less than 3
2. bag_ounces greater than 10
3. else part.
we put the condition in the above if-else statement and print the corresponding message.
