You would like to develop a web-based application for patient appointments. The application will allow a patient to make doctor appointments online. For making an appointment, a patient must provide information, such as name, citizen ID, Hospital number (if available), clinical signs and symptoms (to send the patient to the appropriate clinic).
This web-based application requires a computer network and server to operate. However, there is only one IT officer in your hospital, mostly working on fixing computers. Your hospital does not have its own server yet. You propose to the executive board that a cloud server should be used for this project. So, you must provide information to the executive board.– Why would you choose cloud server, rather than physical server?
– What kind of cloud computing service model would be most appropriate (SaaS, PaaS, IaaS)? Why? -
Why would you choose cloud server, rather than physical server?
I will choose cloud server because there is no big initial investment to buy a physical server, and it operates on pay per use model which allows a lower entry barrier. Moreover, we do not need to buy a huge physical server to handle maximum workload because cloud server can scale up and down easily with fluctuating workload. As the cloud service provider manages all hardware, security and maintenance of servers, our IT officer can focus on his/her essential tasks, rather than server upkeep. In summary, using a cloud server reduces upfront costs, maintenance, and IT workload while providing scalability and reliability.What kind of cloud computing service model would be most appropriate (SaaS, PaaS, IaaS)? Why?
For our hospital, a SaaS solution is the most appropriate solution. Because it has no big upfront cost, rapid deployment to the end users (patients) and minimum maintenance similar to cloud servers. We will choose PaaS and develop a custom web-based application, only if we already had the blueprint of hospital’s enterprise architecture and there is no SaaS that can fit into that architecture design. Otherwise, it will contradict the points we provide for the executive board. -

I want to propose choosing the cloud server rather than the physical server because of the following reasons:
1. Access to resource: Easy and fast access to computing power and storage, without purchasing expensive hardware
2. Mobility: The doctors and the patients can be accessed from anywhere in the world
3. Scalability: The cloud services use a monthly subscription and pay-as-you-go model. So, we can scale up or down based on the case load, patient demands, without over-investment
4. Data security: The providers offer strong security, such as encryption, backups
5. Cost effectiveness: No need the large investments in servers, equipment, or additional IT staff. This is cost-effective rather than a physical server
6. Maintenance and support: The providers handle the system updates and technical support, which reduces the burden on IT staffMoreover, I think Platform as a Service (PaaS) is the most appropriate cloud computing service model in the given setting. If we choose the Software as a Service (SaaS), the software may not fit the requirements of the hospitals. If we choose the Infrastructure as a Service (IaaS), the hospital may need more IT staff, or the existing IT staff can have an increased workload. So, I would like to propose choosing the PaaS to customize the patient appointment needs with interoperability measures without worrying about the server setup and technical issues.

Q1: Why would you choose cloud server, rather than physical server?
I would choose a cloud server rather than a physical server because it offers several advantages that are particularly important in the hospital setting.
1. Mobility: Patients can conveniently use a web-based application to make doctor appointments from any location where the cloud service is supported. This helps reduce waiting time, improves accessibility, and makes health services more efficient. On the other side, healthcare providers can check, and monitor patients’ data through the app from anywhere, which ensures better continuity of care.
2. Scalability: As the number of patients or services increases, cloud servers allow the system to be expanded quickly without the need to invest in additional physical infrastructure.
3. Data security: Protecting patient information is a top priority in any hospital. Cloud servers offer reliable data protection through encrypted storage, routine backups, and disaster recovery systems. This minimizes the risk of losing sensitive health records and ensures compliance with data protection standards.
4. Cost savings: Compared to physical servers, cloud services reduce the need for heavy investment in IT infrastructure, equipment, and server space. The hospital can save on hardware purchases, and electricity.
5. Maintenance and support: With cloud servers, maintenance responsibilities are handled by the service provider. This reduces the burden on the hospital’s IT staff and ensures timely updates, technical support, and troubleshooting.Q2: What kind of cloud computing service model would be most appropriate (SaaS, PaaS, IaaS)? Why?
In my opinion, the SaaS model would be the most suitable choice for the given scenario. Since the hospital has only one IT officer, it would be difficult to handle all the responsibilities that come with maintaining applications, servers, and infrastructure. By using SaaS, the cloud service provider will take full responsibility for managing the application, data, runtime, middleware, servers, storage, and networking. This reduces the technical burden on the hospital and allows the IT officer to focus on supporting daily operations rather than struggling with complex maintenance tasks.

1) I would rather recommend cloud server because physical server is more costly and require IT officer to maintain and fixing issue all the time. Could server is interactive and easily accessible with minimal effort. We can buy a cloud server with effective cost and can assure easily accessibility, mobility, data security and scalability. Moreover, maintenance and support that are taking responsible by service providers. We can spare our IT resource in fixing issues.
2) What kind of cloud computing service model would be most appropriate (SaaS, PaaS, IaaS)? Why?
SaaS is the most appropriate because it is software based and we can easily rely on provided services. It is more user friendly and effective ways. Cloud infrastructure are upgrading all the time based on consumers’ demands and experiences. We can make choice based on hospital requirements and can request to be user friendly model. -

– Why would you choose cloud server, rather than physical server?
Cloud computing is a model for enabling ubiquitous to share among users at anytime, anywhere. If my hospital uses hybrid cloud and web-based application for patient appointments, the first will be cost saving, having mobility, easy to give support and maintenance. The most important reason is using cloud server will ensure the data security as we have to collect the biometric and personal information from the patients. Moreover, we can make EMR for each patient and store at cloud server.– What kind of cloud computing service model would be most appropriate (SaaS, PaaS, IaaS)? Why?
As my hospital is initiating to transform from stand alone computer to cloud computing having insufficient infrastructure (server) and IT staff, I would like to choose SaaS server model. SaaS not need variety of costs or efforts to start. It can provide the users with remote access through a web browser which our hospital intended to deploy for patients’ appointment. The different sites of hospital can communicate with each other directly through a link in SaaS model because it uses Bus Topology. And hospital only has to pay for use of the application: gigabyte model. The developer provides SaaS and the users do not need to download., is reliable and simple to use. -
Since I would like to develop a web-based application for patient appointments but there is only one IT officer working in the hospital, I would propose to the executive board the use of a cloud server for the project, particularly the PaaS service model for the following reasons:
1. In the PaaS cloud service model, the user has control over the deployment and configuration settings for the application. I can build, deploy, and manage a web-based application for patient appointments based on the hospital’s needs, without worrying about the management and control of the underlying cloud infrastructure (network, servers, operating system, and storage).
2. Compared to managing an application that runs on a physical server, using the cloud server for the application will lessen the burden for the IT officer (who is already in charge of fixing computers), since the cloud service provider will be one responsible for managing and controlling the underlying cloud infrastructure.
3. Resources on the cloud can be used anytime, anywhere, as long as there is an internet connection. The IT officer can monitor the status of the application even when he/she is away from work.
4. Using a cloud service can provide a better processing power and larger storage capacity for the application, without the high upfront cost of operating a physical server in the hospital.
5. A cloud server is easily scalable and services can be expanded. In the future, if the hospital wants to include more features to the web-based application, it can be easily done.

1. Why Choose a Cloud Server instead of a Physical Server?
Using a cloud server is more practical and cost-effective than investing in a physical server, especially considering our current limitations. Our hospital lacks a dedicated server and has only one IT officer who is mainly responsible for basic computer maintenance. Setting up a physical server would require significant investment, ongoing maintenance and specialized IT expertise that we currently do not have. In contrast, a cloud server can be deployed quickly with minimal initial cost, offers high reliability and availability, and includes built-in data backups and security managed by the provider. Cloud solutions are also highly scalable, allowing us to easily expand system resources as the hospital grows or as patient demand increases. This approach minimizes downtime, ensures secure access and reduces the technical burden on our small IT team.2. Recommended Cloud Computing Service Model:
For this project, the most appropriate cloud computing model is Software as a Service (SaaS). SaaS allows us to use ready-to-deploy web-based software hosted and maintained by a third-party provider, eliminating the need for us to build, host or manage the application infrastructure ourselves. This model is suitable for our limited IT resources and the urgent need to get the appointment system running smoothly and quickly. A SaaS solution would include patient scheduling, data entry forms and even reporting tools that all accessible via a web browser with no need for installation or complex setup. It also ensures automatic updates, security compliance and technical support, helping our team stay focused on healthcare delivery rather than software maintenance. Overall, SaaS offers a fast, efficient, and reliable way to introduce digital appointment booking to our hospital with minimal operational complexity. -

I propose choosing the cloud server over the physical server based on the following reasons:
– Mobility: Users can work anywhere, as their tasks are mobile within the hospital.
– Scalability: It is easier to scale up and down. For example, during the outbreak with more patients, the cloud server can handle increased patients demand, and it can be scaled down when the demand declines, providing flexibility.
– Data security: Cloud providers professionally take care the security following established protocols and regulations, which our single IT officer cannot easily handle. They also provide backup and recovery.
– Cost saving: No need to buy servers or pay for the maintenance cost.
– Maintenance and support: With only one IT officer, the cloud server reduces their workload as the cloud provider already do these tasks.And I propose that the PaaS would be appropriate for our web-based patient appointment app for the following reasons:
– PaaS provides platform for app development including the servers, databases, and tools. Therefore, with our hospital setting, it offers fast development and less burden on our IT officer. We can build a customized system for our hospital without worrying about handing the infrastructure, security, or backup.
– IaaS may not be the most suitable type, because although it provides server, storage, and network, but we still require more IT work to manage and maintain them..
– SaaS also may not suitable for our hospital setting. While it offers the infrastructure and platform, but it also provides a ready-to-use software that limits our flexibility to customize the app to fit our hospital.

I would choose cloud server rather than physical server due to the following reasons:
1. Scalability and flexibility: The cloud server can easily scale up to handle more appointments or clinics if the patient demand increase, without needing new hardware.
2. Mobility: Patients and healthcare professionals can use the system from mobile devices or computers so it will be easier to schedule and check appointments without physically going to the hospital.
3. Data security: Cloud providers usually make regular updates to secure the sensitive patient data such as data encryption, secure authentication so that makes protecting patient information.
4. Maintenance and support: With limited IT staff, maintaining a physical server would be challenging. Cloud servers are managed and updated by the provider, reducing the burden on the hospital’s single IT officer.
5. Access to resources: As it is a cloud server, it allows authorized staffs and patients to access the appointment anytime and anywhere with internet connection.
6. Cost savings: Using a cloud server will be cost effective without needing to maintain as physical servers.
I suppose PaaS would be appropriate because it provides everything needed to build and run on the appointment system, while removing the burden of infrastructure management. It would be practical, secure, and cost-efficient for a hospital with limited IT resources. -
To develop an application for hospitals, the following facts are worth considering:
• There are data privacy concerns as patients must provide information
• The hospital has only one IT officer
• The hospital does not currently have its own serverWhy would we choose cloud server, rather than physical server?
Data protection: Physical server can be more likely to encounter physical threats/fire/natural disasters and disruptions, that might cause data loss all at once.
Cloud servers are more reliable with many redundancies across multiple data centers.
Data privacy: Data breaches are less likely with cloud servers, as cloud providers can offer advanced security measures
Costing: Physical servers need more initial setup and maintenance costs.
Maintenance and data backups: As we have only one IT officer, cloud server is more appropriate as there is no need to manually backup the data and maintain the server.
Scalability: As hospital data storage is only to be growing and expanding, cloud servers are more scalable and flexible in changing demands and needs.
Rapid development and deployment: With cloud server, we can only focus on application development and deployment, not the server infrastructure. Therefore, the process will be faster.What kind of cloud computing service model would be most appropriate (SaaS, PaaS, IaaS)? Why?
The most appropriate cloud computing service model – PaaS
Fast development: As we need to focus only on coding and application development, rather than infrastructure
Customization: Application designs and modules are customized as needed, contrary to SaaS.
Reduce IT burden: PaaS will reduce IT burden for updates, backups and basic security compared to IaaS.
Cost efficiency: PaaS is less complex and costly than IaaS.
Data privacy: With a hybrid setup, sensitive data can be stored on hospital’s private cloud and non-sensitive data on PaaS. This way, we can still get the benefits of PaaS on scalability and managed infrastructure, while ensuring data privacy.-
Thanks for sharing, Ahma. PaaS would be the best fit for the hospital setting.
Just for sharing, you may already know about the platforms below.Nowadays, we can easily transform our ideas into real-world apps without requiring the coding knowledge with the help of AI-driven coding.
Among the free platforms, I like vercel (https://vercel.com/) for building apps with more advanced features and beatiful UI design. I am also using Streamlit (https://streamlit.io/) in my work to create data apps. for example, automation to check our databases based on the rule-based criteria and data transformation.

Why would you choose cloud server, rather than physical server?
I would choose a cloud server instead of a physical server for the patient appointment system because it is cheaper, easier to manage, and more reliable. A physical server would require a large upfront investment in hardware, maintenance, security and backup systems. On the other hand, cloud servers can run a pay-as-you-go model which means we only pay for the resources we use. Since our hospital has only a IT officer, the cloud servers would be easier to manage because the provider takes care of updates, backups, and security. Moreover, they can easily scale up if the app performance and storage are needed to increase in the future. In addition, cloud providers such as Google Cloud and AWS follow international standards for data security in handing sensitive patient information.What kind of cloud computing service model would be most appropriate (SaaS, PaaS, IaaS)? Why?
In the short term, I would choose SaaS such as Google Appsheet or Microsoft Power Apps based on the eco system of our hospital’s emails. These no-code platforms can be considered as SaaS, but it has also the characteristics of PaaS. They can be used to create, customize and deploy apps without worrying about the backend like other PaaS tools. It would allow us to quicky build a patient appoint system without needing knowledge of coding because we have only one IT officer in our hospital.
In long-term, most appropriate option would be PaaS such as Google App Engine and AWS. It would be better for us to develop a custom web application that fits our hospital’s specific needs and integrates with other platforms and advanced features in the future.
In conclusion, I prefer starting with a SaaS like Google Appsheet for a quick, low-cost deployment. Then, move to a PaaS like Google App Engine for a scalable, secure and customized long-term system. -

1. Why choose a cloud server instead of a physical server?
Lower cost – No need to buy expensive hardware and maintain a server room. We only pay for what we use.
Less IT workload – Our one IT officer cannot handle server setup, maintenance, and security. The cloud provider will manage those.
Scalability – If more patients use the system in the future, we can easily expand storage and computing power without buying new equipment but the fees might rise a little according to usage eventually.
High availability – Cloud servers usually have backups for data recovery in cases of disasters.
Security – Major cloud providers include advanced security feature which is better than on-site security.
Accessibility – Staff and patients can access the system from anywhere with an internet connection.2. Most appropriate cloud computing service model
Software as a Service (SaaS) would be the most appropriate model if we use an existing appointment system provided by a cloud company because the application is already developed by the company and ready to use and we only manage patient data and usage, not the software or servers which is convenient for a small hospital with limited (only one) IT staff. -
