Role-specific Cloud Computing Architecture Interview Questions & Answers:

1. Explain business benefits involved in cloud architecture?

The benefits involved in cloud architecture is:
► Zero infrastructure investment
► Just in time infrastructure
► More efficient resource utilization

2. Explain different components that are required in Cloud Computing Architecture?

► Cloud Ingress
► Processor Speed
► Cloud storage services
► Cloud provided services
► Intra-cloud communications

3. what are the different phases involved in Cloud Computing Architecture?

► Launch Phase
► Monitor Phase
► Shutdown Phase
► Cleanup Phase

4. What is zero client?

The zero or ultra-thin client initializes the network to gather required configuration files that then tell it where its OS binaries are stored. The entire zero client device runs via the network. This creates a single point of failure, in that, if the network goes down, the device is rendered useless.

5. What is IaaS in Cloud Computing Architecture?

Infrastructure as a service is taking the physical hardware and going completely virtual (e.g. all servers, networks, storage, and system management all existing in the cloud). This is the equivalent to infrastructure and hardware in the traditional (non-cloud computing) method running in the cloud. In other words, businesses pay a fee (monthly or annually) to run virtual servers, networks, storage from the cloud. This will mitigate the need for a data center, heating, cooling, and maintaining hardware at the local level

6. What is PaaS in Cloud Computing Architecture?

Platform as a service is cloud computing service which provides the users with application platforms and databases as a service. This is equivalent to middle-ware in the traditional (non-cloud computing) delivery of application platforms and databases.

7. What is DaaS in Cloud Computing Architecture?

Development as a service is web based, community shared development tools. This is the equivalent to locally installed development tools in the traditional (non-cloud computing) delivery of development tools.

8. What is SaaS in Cloud Computing Architecture?

The software-as-a-service (SaaS) service-model involves the cloud provider installing and maintaining software in the cloud and users running the software from their cloud clients over the Internet (or Intranet). The users' client machines require no installation of any application-specific software - cloud applications run on the server (in the cloud). SaaS is scalable, and system administration may load the applications on several servers. In the past, each customer would purchase and load their own copy of the application to each of their own servers, but with the SaaS the customer can access the application without installing the software locally. SaaS typically involves a monthly or annual fee.

9. What are the building blocks in Cloud Computing Architecture?

► Reference architecture
► Technical architecture
► Deployment operation architecture

10. What is Cloud computing architecture?

Cloud computing architecture refers to the components and sub components required for cloud computing. These components typically consist of a front end platform (fat client, thin client, mobile device), back end platforms (servers, storage), a cloud based delivery, and a network (Internet, Intranet, Inter-cloud). Combined, these components make up cloud computing architecture.
