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.
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.
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.
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) 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.
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.
"EUCALYPTUS" stands for your program to connect to a practical system of resilient utility computing architecture.
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.
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.
a) Compliance
b) loss of data
c) data storage
d) business continuity
e) uptime
f) Data integrity cloud
Open source cloud computing platform database are:
a） MongoDB
b） CouchDB
c） LucidDB
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.
A) Google Bigtable
b) Amazon simpleDB
c) cloud-based SQL
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.
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.
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.
Cloud computing data center comprising different, such as
a) a container datacenter
b) Low Density Data Center
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.
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.
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.
A) Professional Cloud
B) the private cloud
C) High performance Cloud
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.
Cloud architecture has benefits include:
a) no infrastructure investment
b) timely infrastructure
c) more efficient use of resources
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.
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.
Window Azure provides three core services include:
a) computing services
b) storing service
c) Management Services
a) Inbound cloud
b) a processor speed
c) cloud storage service
d) a cloud service provider
e) the communication between the Cloud
a) start-up phase
b) monitoring phase
c) closing phase
d) cleaning phase
a) flexibility and scalability
b) self-configuration and the configuration is automatically canceled
c) standardized interfaces
d) self-charging mode of use
a) reference architecture
b) Technical Architecture
c) architecture deployment operation
In order to provide transparency, performance 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.
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.
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.
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.
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.
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.
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.
