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 second part of the version you! Interested parties can discuss the message, we also welcome supplement!
18) Can explain the software as a service (SaaS) different modes?
a) Simple multi-tenant mode: In this mode, each user has a separate resources to separate from other users, this is an efficient mode.
b) fine-grained multi-tenant mode: In this mode, the resource is shared by a number of tenants, but the functionality is still the same.
19) API What is the purpose in the cloud?
API (Application Programming Interface) is very useful in cloud platform
a) the need to write a full-featured program.
b) providing an instruction to contact between one or more applications.
c) easy to build applications and cloud services to link with other systems.
20) for cloud computing deployments What are the different data centers?
Cloud computing data center comprising different, such as
a) a container datacenter
b) Low Density Data Center
21) What are the different layers of cloud computing there?
Different cloud layer comprises:
a) SaaS: Software as a service that allows users to directly access cloud applications, without having to install anything on the system.
b) IaaS: Infrastructure as a Service, which provides infrastructure from hardware (such as memory and processor speed, etc.) and other levels.
c) PaaS: Platform as a Service, which provides cloud application platform for developers.
22) How important platform as a service?
Platform as a Service (PAAS) is a very important cloud layer. It provides an application platform provider. It is responsible for providing the infrastructure layer of virtualized, it as a single server up and running.
23) What cloud services?
Cloud services are used to build cloud applications via the Internet, using a network server. It provides this convenience: no need to install cloud applications to your computer, can be used directly. It also reduces the application's job to maintain and support the use of cloud services development.
24) three lists whether cloud computing basic cloud?
A) Professional cloud
B) Private Cloud
C) High Performance Cloud
25) on infrastructure as a service, it offers what resources?
IAAS (Infrastructure as a Service) provides a virtual and physical resources used to build the cloud. It is responsible for handling the complexity of deployment and maintenance services to bring this layer provides. Here, infrastructure servers, storage systems and other hardware systems.
26) What kind of cloud architecture business benefits?
Cloud architecture has benefits include:
a) no infrastructure investment
b) timely infrastructure
c) more efficient use of resources
27) cloud architecture is different from the characteristics of the traditional architecture of what?
Unlike traditional infrastructure to cloud architecture features include:
a) on demand, cloud architecture to meet the hardware requirements.
b) cloud architecture can increase or decrease the resources needed.
c) cloud architecture to manage and handle dynamic workloads, smooth and unhindered.
28) Can include cloud elastic extensibility and difference?
Scalability is a characteristic cloud; means scalability, as long as the resources corresponding increase in capacity can handle the increased workload. As another feature of cloud computing, the concept of elasticity emphasized enabled and disabled huge resource capacity.
29) the possibility of listing the service provided by the Window Azure operating system?
Window Azure provides three core services include:
a) computing services
b) storage services
c) management services
30) In the cloud architecture, the different parts of what is necessary?
a) Inbound Cloud
b) a processor speed
c) cloud storage service
d) cloud service provider
e) the communication between the Cloud
31) In the cloud architecture, we experienced different stages of what?
a) start-up phase
b) monitoring phase
c) closure phase
d) clean-up stage
32) Can lists the basic characteristics of cloud computing?
a) flexibility and scalability
b) self-configuring and automatically canceled configuration
c) standardized interfaces
d) the use of self-charging mode
33) In the cloud architecture, the basic building blocks of what?
a) Reference Architecture
b) technical architecture
c) deployment operations architecture
34) Can describe ways in which cloud infrastructure to provide automated performance and transparency?
In order to be able to ××× transparency and automation, cloud architecture uses many tools. It can manage cloud infrastructure and monitoring reports. It also can share applications that use cloud architecture. Automation is a key part of the cloud infrastructure, help to improve the quality level.
35) Can explain the role of high-performance cloud in the Cloud?
High-performance cloud in terms of data transfer immediately the maximum number of useful. In high-performance computing research professionals often use high-performance cloud.
36) Can explain hybrid cloud and community cloud?
Hybrid Cloud: Hybrid Cloud includes a number of service providers. It combines public and private cloud capabilities. The company also needed private and public clouds, hybrid clouds will be used.
Community cloud: the cost of this model is very high; many organizations have common goals and needs, and ready to share the advantages of cloud services, it will use community cloud.
37) in the cloud, optimization strategies What?
In order to overcome maintenance costs and optimize resources, uses three data centers cloud concept: to provide backup and recovery mechanisms in case of a disaster or system failure, ensures that all data is safe.
38) Amazon SQS what stuff?
For links between the different connections, it is necessary to use Amazon SQS message; it acts as a "liaison" in different components of the Amazon.
39) How buffer for Amazon Web Services?
To make the system more efficiently respond to a situation or a sudden load of traffic, providers use a buffer. Synchronization buffer may be different components. Assembly in an unbalanced manner always receive and process requests. Balance between the different components of the buffer to be responsible for the management, so that they come to work at the same rate, so as to provide faster service.
40) Can describe the type of hypervisor and cloud computing?
Hypervisor virtual machine monitoring tool for virtual machine management resources. Hypervisor There are two main types.
Type 1: guest virtual machines running directly on the host hardware, such as Xen and VMWare ESXI.
Type 2: guest virtual machine running on hardware by the host operating system, such as KVM and Oracle VirtualBox.
