[HARD] U1-1: Introducing the SAP S/4HANA Cloud Deployment Options Flashcards
What is cloud computing?
Cloud computing refers to the delivery of applications, platforms, data storage, operating systems, and other computing resources over the Internet. It allows users to access and utilize these resources from remote servers rather than relying solely on their local devices.
How is cloud computing different from traditional on-premise models?
In a traditional on-premise model, the customer is responsible for providing and maintaining the server, software, and all necessary resources and personnel. However, with cloud computing, customers can subscribe to the specific computing resources they need, access them instantly, and only pay for direct usage. The responsibility for maintaining the infrastructure and managing the resources shifts to the cloud service provider.
What is the payment model in cloud computing?
In the cloud computing model, customers pay a regular subscription fee to consume certain services from a third-party provider. This subscription-based payment model allows organizations to optimize their expenses by paying for the resources they use, similar to how one pays for utility services such as water and electricity.
What is the advantage of accessing cloud resources over the Internet?
Accessing cloud resources over the Internet enables users to tap into near-infinite resources located in other locations. This means that despite the limitations of local devices, such as finite storage capacity, users can leverage the vast computing resources available through the Internet to meet their needs.
How does cloud computing contribute to resource optimization and cost savings?
Cloud computing allows organizations to scale resources up or down quickly to meet fluctuating workload requirements. This elasticity enables efficient resource allocation, ensuring that users only pay for the resources they use. By minimizing hardware and IT costs and adopting a pay-as-you-go pricing model, cloud computing offers affordability and cost-effectiveness, making it an attractive option for businesses.
What does elasticity refer to in the context of cloud computing?
Elasticity in cloud computing refers to the ability to scale up or down computing resources quickly to meet fluctuating workload requirements. It allows organizations to adjust their resource allocation based on demand, ensuring optimal performance and cost efficiency.
How does agility relate to cloud computing?
In the context of cloud computing, agility refers to the ability to set up and react quickly to changing market conditions and business needs. Cloud solutions provide businesses with the flexibility to rapidly deploy and adapt their applications and infrastructure to stay ahead in dynamic environments.
What is the significance of security in cloud computing?
Security is a crucial aspect of cloud computing. It involves implementing measures to improve compliance, protect data, and mitigate risks associated with unauthorized access, data breaches, and cyber threats. Continuous security updates and robust security protocols are essential to ensure the integrity and confidentiality of cloud-based systems.
How does cloud computing contribute to innovation?
Cloud computing enables organizations to rapidly adopt new technologies and innovate faster while simplifying IT’s role.

What does availability mean in the context of cloud systems?
Availability refers to the ability to access cloud systems and resources 24/7 from anywhere and on any device with an internet connection. Cloud providers ensure high availability by maintaining robust infrastructure, redundant systems, and reliable network connectivity, allowing users to access their applications and data whenever needed.
How does cloud computing contribute to affordability?
Cloud computing offers affordability by adopting a pay-as-you-go model where organizations only pay for the resources they use. This helps minimize hardware and IT costs as businesses can leverage the cloud provider’s infrastructure instead of investing in and maintaining their own. It provides cost optimization by eliminating upfront investments, scaling resources based on demand, and avoiding the expenses associated with managing on-premise infrastructure.
What is the main characteristic of a public cloud?
A public cloud is characterized by a multi-tenant server where customers share the resources of the server. However, each customer’s data and applications are hidden from the other customers, ensuring data privacy and security.
Why is the public cloud often considered an affordable and efficient solution?
The public cloud is often considered affordable and efficient due to the shared resources model. By sharing infrastructure and costs among multiple customers, the expenses are distributed, making it a cost-effective option. Additionally, the public cloud offers scalability and flexibility, allowing customers to pay for the resources they use, further optimizing costs.
What is a private cloud?
A private cloud is a cloud deployment model where a third-party provider owns the server and is responsible for its maintenance. Customers pay a subscription fee to access the server over the internet and install software. In the case of SAP, they are responsible for maintaining the business software, while customers can choose to have their software on a server in an SAP data center or a server in a data center from one of their hyperscaler partners.
What is the key characteristic of a hybrid cloud?
A hybrid cloud includes both cloud and on-premise solutions and is often sourced from multiple providers. It allows organizations to leverage a combination of cloud and on-premise resources, providing flexibility, scalability, and the ability to integrate existing systems with cloud-based solutions.
How can customers leverage the SAP Business Technology Platform in a hybrid cloud environment?
Customers can leverage the SAP Business Technology Platform to develop and host cloud-native integrations and applications that connect their solutions in a hybrid cloud environment. The platform enables organizations to build, deploy, and manage applications that seamlessly integrate both cloud and on-premise components, facilitating hybrid cloud deployments and enhancing overall system connectivity.
What are the benefits of leveraging a hybrid cloud architecture?
A hybrid cloud architecture offers several benefits, including the ability to choose the most suitable deployment model for each workload, increased flexibility and scalability, seamless integration of on-premise and cloud solutions, and the ability to leverage existing investments while taking advantage of cloud capabilities. It provides organizations with the flexibility to optimize their IT infrastructure based on specific requirements and business needs.
What is Software as a Service (SaaS)?
Software as a Service (SaaS) is a computing service where a third-party cloud provider hosts applications and makes them available to customers over the internet. With SaaS, customers can access applications directly from a web browser without the need to purchase, install, or maintain hardware or software. The SaaS provider takes care of everything, including updates, ensuring customers always have the latest version of the application.
