Module 1: Intro to AWS Flashcards
What is a client in computing?
A client refers to a web browser or desktop application that a person interacts with to make requests to computer servers.
What is a server in computing?
A server represents services such as Amazon Elastic Compute Cloud (Amazon EC2) or a type of virtual server. It evaluates client requests and fulfills them by returning the requested information.
What are the three cloud computing deployment models?
The three cloud computing deployment models are cloud-based, on-premises, and hybrid.
What is the cloud-based deployment model?
In the cloud-based deployment model, all parts of the application run in the cloud. It allows for migrating existing applications to the cloud and designing/building new applications in the cloud.
What is the on-premises deployment model?
In the on-premises deployment model, resources are deployed on premises using virtualization and resource management tools. It is also known as a private cloud deployment.
What is the hybrid deployment model?
In the hybrid deployment model, cloud-based resources are connected to on-premises infrastructure. It allows for integrating cloud-based resources with legacy IT applications and is useful in scenarios where certain applications need to remain on premises.
What is the benefit of trading upfront expense for variable
By trading upfront expense for variable expense, companies only pay for the computing resources they consume instead of investing heavily in data centers and servers beforehand.
What is one advantage of cloud computing in terms of data center management?
Cloud computing allows companies to focus less on managing infrastructure and servers in data centers, freeing up resources to focus on applications and customers.
How does cloud computing eliminate the need to guess capacity?
With cloud computing, companies can launch instances or resources as needed and pay only for the compute time they use. This eliminates the need to predict infrastructure capacity and allows for scaling in or out based on demand.
What is the benefit of benefiting from massive economies of scale in cloud computing?
By using cloud computing, companies can achieve lower variable costs due to the higher economies of scale of cloud providers. This translates into lower pay-as-you-go prices for customers.
How does cloud computing increase speed and agility in application development and deployment?
The flexibility of cloud computing enables faster development and deployment of applications, providing more time for experimentation and innovation. Resources can be accessed within minutes compared to the weeks it may take in traditional data centers.
What advantage does the global footprint of the AWS Cloud provide?
The global footprint of the AWS Cloud allows for quick deployment of applications to customers around the world with low latency, enabling global accessibility and minimal delays.
