Microsoft Azure Interview Questions and Answer

What is the difference between Web Hosting, Dedicated Servers and Cloud Computing?

Web hosting refers to the service of providing storage space and access for websites. A website is hosted on a server, which is a computer or network of computers that store the files that make up a website.

Dedicated servers refer to the renting of an entire physical server from a hosting provider. This means that the user has full control over the server, including the operating system and hardware.

Cloud computing refers to the delivery of computing resources, such as storage, processing power, and memory, over the internet. Instead of having to purchase and maintain physical servers, users can access these resources on-demand from a cloud provider.

In summary:
  • Web hosting is a service for storing and accessing websites.
  • Dedicated servers are physical servers that are rented out to users.
  • Cloud computing is the delivery of computing resources over the internet.

What are the use of Cloud Computing?

Cloud computing is used for a variety of purposes, including:

Data storage and backup: Cloud storage services, such as Amazon S3 and Google Drive, allow users to store and access large amounts of data remotely. This makes it easy to backup important files and access them from anywhere.

Computing power: Cloud computing services, such as Amazon EC2 and Google Compute Engine, allow users to rent virtual machines with different configurations of CPU, memory, and storage. This makes it easy to scale up or down computing resources as needed.

Software as a service (SaaS): Many software applications, such as Microsoft Office 365 and Salesforce, are now offered as cloud-based services. This allows users to access the software from any device with an internet connection.

Platform as a service (PaaS): Platform as a service allows developers to easily deploy, run, and manage applications without the complexity of building and maintaining the underlying infrastructure.

Infrastructure as a service (IaaS): Infrastructure as a service provides virtualized computing resources over the internet, such as virtual machines, storage, and networking, which is used to build and manage IT infrastructure.

Business Continuity and Disaster Recovery: Using cloud computing to store and access data remotely can provide a level of business continuity and disaster recovery that may be difficult to achieve with traditional on-premises infrastructure.

Artificial Intelligence and Machine Learning: Cloud computing providers offer AI and ML services that allows developers to build, train and deploy AI models at scale.
