A few days ago in a small study group where some partners asked questions related to cloud computing interview was given some problems, suffer no typing too tired to write anymore, but think this is a very irresponsible, so finishing down possession of a bit in recent years, especially to share to finish the first part of the version you! Interested parties can discuss the message, we also welcome supplement!
1) What are the advantages of using cloud computing?
Cloud computing has the following advantages:
a) backup of data and storage data
b) powerful server functions
c) SaaS (software as a service)
d) Information technology sandboxing
e) improve productivity
f) cost-effective, and save time
2) Can enumerate what platforms for large-scale cloud computing?
Platform for large scale cloud computing include:
a） Apache Hadoop
b） MapReduce
3) Can be used to explain the different modes of cloud computing deployment?
Different cloud deployments mode comprises:
a) private cloud
b) Public Clouds
c) Community Cloud
d) mixing clouds
4) What is the difference between cloud computing and mobile computing?
Using the same concept of mobile computing and cloud computing. With the Internet rather than by individual devices, cloud computing because the data becomes active. It provides data that needs to demand access to users. In mobile computing, the applications running on a remote server, provides users with access to the stored data.
5) How do users benefit from utility computing (utility computing)?
Utility computing allows users to pay only for the resources used. It is a plug-in consists decide what type of cloud service deployment from the organization management.
Most organizations favor a mixed strategy.
6) Since the data transmission in the cloud, how do you ensure data security?
The process of transferring data from one place to another place of want to ensure data security, make sure you send data for an encryption key that is used is not leaking.
7) Cloud security measures what?
a) Identity Management: Authorization Application Services.
b) access control: grant user permissions, so the user can control into another user access to cloud environments.
c) Authentication and Authorization: allows clients to access data and applications by the authorization and authentication.
8) whether the definition lists the different layers of cloud architecture?
8) use different layers of cloud infrastructure comprising:
a) CLC i.e., cloud controller
b）Walrus
c) Cluster Controller
d) SC i.e., the memory controller
e) NC node controller i.e.
9) What is the role of cloud computing systems integrator that?
In cloud computing, systems integrator responsible for the complex process used to design the cloud platform to develop strategies. Integrators need to build more accurate hybrid and private cloud network, because integrators to build data centers have all the knowledge.
10) What is "EUCALYPTUS" stands for?
"EUCALYPTUS" stands for your program to connect to a practical system of resilient utility computing architecture.
11) Can explain "EUCALYPTUS" what is the use in the cloud?
Eucalyptus is an open source cloud computing infrastructure software, which is used to implement the cluster to the cloud computing platform. It is used to build public cloud, hybrid cloud and private cloud. It can be your own private cloud data centers to fight and make you their functions can be applied to many other organizations.
12) virtualization platform what is required in the implementation of cloud?
Virtualization platform in the cloud implementation requirements include:
a) Service Level Management Strategy
b) cloud operating system
c) virtualization platform will help make differ from each other back-end conceptual level and user-level concepts.
13) prior to use cloud computing platform, which users need the necessary considerations?
a) Compliance
b) Data Loss
c) Data storage
d) Business Continuity
e) Uptime
f) Data integrity cloud
14) Can cited several open source cloud computing platform database?
Open source cloud computing platform database are:
a） MongoDB
b） CouchDB
c） LucidDB
15) What secure the implementation of safety regulations to protect cloud data?
To protect cloud data security and the implementation of safety regulations include:
a) treating: a control in the application correctly, data integrity processing.
b) File: management and control data that any of the documents processed.
c) Output Harmonic: it controls input and output between the need to reconcile the data.
d) enter: control input data.
e) security and backup: it provides safety and backup, but also compromise safety control log.
16) Can the database name listed several large cloud provider?
a）Google bigtable
b）Amazon simpleDB
c) cloud-based SQL
17) Can explain the difference between cloud and traditional data center?
a) Since the heating and hardware / software problems, the cost of traditional data center is relatively high.
Increases b) demand, cloud resources can be amplified. Most of the expenses spent on maintenance of the data center, and cloud computing is not the case.
