Cloud Quiz - 8kmiles

In cloud computing, the responsibility for physical maintenance of hardware components such as servers, hard disks, network routers, and cables lies with the cloud provider. This means that the cloud provider is responsible for ensuring the proper functioning, repair, and replacement of these components as needed. Users of cloud services do not have to worry about the physical maintenance of the infrastructure, as it is taken care of by the provider. This is one of the advantages of cloud computing, as it allows users to focus on their applications and data without having to manage the underlying hardware.

The correct answer is "All of the above" because all the mentioned advantages - on demand scaling, reliability through data redundancy, and utility computing - pay per use - are indeed advantages of cloud computing. On demand scaling allows users to easily and quickly increase or decrease their computing resources as needed. Reliability through data redundancy ensures that data is backed up and protected from loss. Utility computing - pay per use allows users to only pay for the resources they actually use, making it cost-effective. Therefore, all these advantages make cloud computing a highly beneficial option.

The statement is true because Facebook, Twitter, and Gmail are all web-based applications that are accessed and operated through the internet. These applications store and process data on remote servers, which are part of a cloud computing infrastructure. Users can access these applications from any device with an internet connection, and the data is stored and managed centrally on the cloud servers. Therefore, Facebook, Twitter, and Gmail are examples of applications that are built and run on the cloud.

Amazon Web Services (AWS) is indeed one of the leading cloud platform providers. AWS offers a wide range of cloud-based services and solutions, including computing power, storage, databases, analytics, and more. It is widely recognized and utilized by businesses and individuals around the world for its reliability, scalability, and extensive feature set. With its global infrastructure and comprehensive suite of services, AWS has established itself as a dominant player in the cloud computing industry.

The typical way to pay for Cloud services is to pay as you go. This means that users only pay for the resources and services they actually use, rather than signing a long-term leasing agreement or pre-paying a fixed rent. This payment model offers flexibility and cost-effectiveness, as users can scale their usage up or down based on their needs and only pay for what they consume.

An application in the Cloud can only be launched through a platform, typically a web browser. This means that users need to access the application through a web browser in order to use it. Other methods of launching the application, such as through a desktop application or a mobile app, are not possible in this scenario. Therefore, the statement that the only way an application in the Cloud can be launched is through a platform, in most cases a web browser, is true.

Cloud computing refers to the practice of accessing and utilizing computing resources, such as servers, storage, and applications, over the internet on an as-needed basis. It allows users to scale their computing power up or down based on their requirements, without the need for physical infrastructure or hardware. This model provides flexibility, cost-effectiveness, and convenience to businesses and individuals, as they can easily access and utilize computing resources whenever they need them, without the hassle of managing and maintaining their own infrastructure.

The given statement is false. In cloud computing, the processing of the core application does not happen in the local system. Instead, it occurs in remote servers or data centers that are accessed via the internet. Cloud computing allows users to access and use applications and services over the internet, without the need for local infrastructure or hardware. This enables scalability, flexibility, and cost-effectiveness for businesses and individuals.

The main services provided by Amazon Web Services (AWS) are EC2 - Elastic Compute Cloud, S3 - Simple Storage Service, and SimpleDB. EC2 allows users to rent virtual computers on which they can run their own applications, while S3 provides scalable storage for data backup and archiving. SimpleDB is a NoSQL database service offered by AWS. Therefore, the correct answer is "All the above," as all three services are provided by AWS.

The correct answer is "On demand computing resource available through the web." This means that a public cloud refers to a type of cloud computing where resources such as virtual machines, storage, and applications are provided to users over the internet. It is accessible to anyone who needs to utilize these resources and can be easily scaled up or down based on demand.
