- employing various software tools
- Training new users
- Working closely with the other developers
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.
Answer:
A loop in a computer program is an instruction that repeats until a specified condition is reached. In a loop structure, the loop asks a question. If the answer requires action, it is executed. ... A computer programmer who needs to use the same lines of code many times in a program can use a loop to save time
Explanation:
Solution :
- Loopback plug --- confirm interface functionality
It is a connector that is used to diagnose the transmission problems.
- Protocol Analyzer --- Analyze network traffic
It is used to capture and analyze the signals as well as data traffic.
- Throughput tester - Measure link speed
- Time Domain Reflectometer (TDR) - Determining the location of cable fault
It is used in determining the characteristics of the electrical lines by observing the reflected waveforms
- Locating a specific cable - Toner probe
