Virtualization & Cloud

Network, storage, and virtualization skills are essential to working with cloud infrastructures because cloud computing relies heavily on these technologies. Network skills are necessary for setting up and managing the communication between different components of the cloud infrastructure. Storage skills are needed to handle the large amounts of data that are stored and accessed in the cloud. Virtualization skills are crucial for creating and managing virtual machines and resources in the cloud. Without these skills, it would be difficult to effectively work with and manage cloud infrastructures.

Google Docs is a type of cloud computing because it is a web-based application that allows users to create, edit, and store documents online. Cloud computing refers to the delivery of computing services over the internet, where users can access and use applications and store data on remote servers instead of on their local devices. Google Docs operates entirely in the cloud, allowing users to access their documents from any device with an internet connection. Therefore, it can be classified as a type of cloud computing.

Before implementing cloud computing technology, a company should consider employee satisfaction, potential cost reduction, and information sensitivity. Employee satisfaction is important because the technology may require training and adjustment for employees, so their satisfaction and comfort with the change should be considered. Potential cost reduction is a key factor as cloud computing can offer cost savings compared to traditional IT infrastructure. Lastly, information sensitivity is crucial as the company needs to assess the level of security and privacy required for their data and ensure that the chosen cloud provider can meet those requirements.

The correct answer is "A cloud architecture maintained within an enterprise data center." This answer explains that a private cloud refers to a cloud infrastructure that is managed and operated within an organization's own data center. Unlike public clouds, private clouds are not accessible to the general public and are typically used by businesses or organizations that prioritize data privacy and security.

Cloud computing has become increasingly popular in recent years, but it also raises concerns about the security of sensitive data. Storing data on remote servers and relying on third-party providers for infrastructure and services can make organizations vulnerable to cyber attacks and data breaches. Therefore, the number one concern about cloud computing is security concerns, as organizations need to ensure that their data is protected and that proper security measures are in place to mitigate any potential risks.

In the context of cloud computing, the term "cloud" represents the internet. Cloud computing refers to the practice of using a network of remote servers hosted on the internet to store, manage, and process data, rather than using a local server or personal computer. The term "cloud" is used metaphorically to represent the vast and interconnected nature of the internet, where data and services can be accessed from anywhere and at any time. Therefore, the correct answer is "Internet."

JavaScript, XML, and PHP are popular languages being used to develop cloud applications based on the current market. JavaScript is a widely used programming language for both front-end and back-end development, making it suitable for cloud application development. XML is a markup language commonly used for storing and exchanging data, making it useful for cloud applications that require data manipulation and interoperability. PHP is a server-side scripting language that is frequently used for web development, including cloud applications, due to its ease of use and wide range of available frameworks and libraries.

DevOps is the correct answer because it refers to the emerging IT function that combines software development (Dev) and IT operations (Ops). With the ability to write and manage applications and infrastructure in the cloud, DevOps aims to streamline and automate the processes involved in software development and deployment. It emphasizes collaboration, communication, and integration between development teams and operations teams, resulting in faster and more efficient software delivery.

Cloud computing is replacing all of the options mentioned in the question. It is replacing corporate data centers by providing a more efficient and cost-effective way to store and manage data. It is also replacing expensive personal computer hardware as cloud services allow users to access applications and data remotely, eliminating the need for powerful hardware. Additionally, it is replacing expensive software upgrades as cloud computing offers software as a service (SaaS), allowing users to access the latest versions of software without the need for costly upgrades.

Amazon Web Services (AWS) is an example of Infrastructure as a Service (IaaS) cloud computing distribution model. In IaaS, the cloud provider offers virtualized computing resources such as servers, storage, and networking infrastructure to users over the internet. Users can manage and control their own operating systems, applications, and data, while the cloud provider is responsible for the underlying infrastructure. AWS provides a wide range of infrastructure services, allowing users to scale their resources up or down as needed, without the need to invest in physical hardware.

The correct answer is "Easier to maintain a cloud network". This is because maintaining a cloud network can be complex and requires expertise in managing and troubleshooting cloud infrastructure. While cloud computing offers many advantages such as scalability, flexibility, and cost-effectiveness, the maintenance aspect can be challenging and may require specialized skills and resources.

IBM Deep blue is not a major cloud computing platform. The major cloud computing platforms are Google Cloud, Microsoft Azure, and Amazon EC2. IBM Deep blue, on the other hand, is not a cloud computing platform but a supercomputer developed by IBM for playing chess.

Amazon EC2 is not a platform as a service (PaaS) but rather an infrastructure as a service (IaaS). While Force.com, Microsoft Azure, and Joyent are all examples of PaaS, which provide a platform for developing, running, and managing applications, EC2 offers virtual servers in the cloud, allowing users to have more control over the infrastructure and operating systems.
