Cloud Computing Main Exam Questions And Answers

What are the three differences that separate out cloud architecture from the tradition one?

The three differences that make cloud architecture in demand are:

1. Cloud architecture provides the hardware requirement according to the demand. It can run the processes when there is a requirement for it.

2. Cloud architecture is capable of scaling the resources on demand. As, the demand rises it can provide infrastructure and the services to the users.

3. Cloud architecture can manage and handle dynamic workloads without failure. It can recover a machine from failure and always keep the load to a particular machine to minimum.

What are the advantages of cloud architecture?

- Cloud architecture uses simple APIs to provide easily accessible services to the user through the internet medium.

- It provides scale on demand feature to increase the industrial strength.

- It provides the transparency between the machines so that users don't have to worry about their data. Users can just perform the functionality without even knowing the complex logics implemented in cloud architecture.

- It provides highest optimization and utilization in the cloud platform

What is the business benefits involved in cloud architecture?

1. Zero infrastructure investment: Cloud architecture provide user to build large scale system with full hardware, machines, routers, backup and other components. So, it reduces the start-up cost of the business.

2. Just-in-time Infrastructure: It is very important to scale the infrastructure as the demand rises. This can be done by taking cloud architecture and developing the application in the cloud with dynamic capacity management.

3. More efficient resource utilization: Cloud architecture provides users to use their hardware and resource more efficiently and utilize it in a better way. This can be done only by applications request and relinquish resources only when it is needed(on-demand).

What are the examples of cloud architectures on which application can run?

There are lot of examples that uses cloud architecture for their applications like:

1. Processing Pipelines: uses like document processing pipelines that convert documents of any form into raw searchable text. Image processing pipelines create thumbnails or low resolution image Video transcoding pipelines convert video from one form to another online Indexing create an index of web crawl data Data mining perform search over millions of records

2. Batch Processing Systems Systems that uses log management or generate reports. Automated Unit Testing and Deployment Testing

3. Websites Instant Websites websites for conferences or events Promotion websites

What are the different components required by cloud architecture?

There are 5 major components of cloud architecture.

1. Cloud Ingress: provides a mean to communicate with the outside world. This can be done with the help of communication methods such as:- Queue based communications- HTTP communications- REST/SOAP- Service Bus

2. Processor Speed: processor speed is the major section on which the whole cloud architecture is based. It provides on demand resources that can be dynamically allocated to the user. It saves lots of cost and has many benefits of virtualization.

3. Cloud storage services: cloud services provide means to store data to users applications. It is used to provide services for different types of storages like: table data, files.

4. Cloud provided services: Additional services are provided by the cloud, like data services, payment processing services, and search or web functionality services.

5. Intra-Cloud communications: it provides a way to communicate with other systems that are using cloud architecture. Providers usually provide services so that one user can communicate easily with another user by being on cloud.

What are the different phases involves in cloud architecture?

There are four phases that basically gets involved in the cloud architecture:

1. Launch phase: it launches the basic services and makes the system ready for communication and for application building

2. Monitor phase: it monitors the services that is being launched and then manages them so that on demand the user will be able to get what he wants.

3. Shutdown phase: it shutdown the services that are not required first and after all the services gets shutdown, and then it closes the system services.

4. Clean-up phase: it clean up the left out processes and services that is being either broken or didn't get shutdown correctly.
