Developing Applications for Cloud Computing

Question 1

4 influences of cloud computing

Answer 1

1. service oriented architecture 2. devops 3. collaborative development 4. application scaling

Question 2

What is service oriented architecture

Answer 2

basically services are easily distributed across cloud infrastructure so we have modules as services, black box operations for consumers

Question 3

What is dev ops

Answer 3

cloud has enabled closer interaction between devs and admin … for example release management, configuration management, monitoring and virtualization

Question 4

what is collaborative development

Answer 4

cloud computing made it easier for large teams across the globe to collaborate

Question 5

5 design principles for cloud applications

Answer 5

1. design as a collection of services 2. decouple data from logic/code 3. avoid excessive communication between components 4. design for scale out rather than scale up 5. make security systemic

Question 6

What is application scaling

Answer 6

cloud computing offers an easily scalable distributed computing environment

Question 7

What is Amdahl’s Law

Answer 7

the idea that the execution of the whole task can be sped up if partial tasks are sped up through parallelization

Question 8

What are the types of parallelization

Answer 8

Task level (problem decomposed to sub tasks) and Data level (data decomposed to sub sets)
