How cloud computing and cloud storage evolve under virtualized architectures

Under the new architecture, the client only needs to keep the input and output devices, through Remote Desktop Connection, into the operating environment running on the virtual machine, using the existing information services.  As the information Service (cloud) and the user (end) have been separated, the cloud architecture has been formed.


　　


Cloud architecture is not a new creation, Web server and browser, also belong to this architecture. However, browser-based client devices, such as network computers (NetBook), did not succeed.  Until the last few years, the explosive growth of smartphones and tablets, Apple's iphone mania, Android phones became mainstream, and tablet computers rocked the laptop market to prove the architecture's power.


　　


It is worth noting that while the cloud services provided by Google, Yahoo, and Facebook are important support for smart devices, most of these services already exist when the concept of a networked computer is proposed. So the failure of the network computer and the success of the tablet, the key is not the cloud services have a major change, but the network computer is based on the web, trying to be recognized as unfriendly standard browser, as output into the interface. Intelligent device is based on the network and services, itself still has a certain degree of computing power, and with the user to operate a convenient output into the interface, the user will naturally be valued.  Therefore, enterprises in the introduction of cloud computing, but also need to measure the user between the work pattern and the working habits of the differences, in order to improve productivity, the allocation of appropriate output devices, as well as network links to achieve maximum benefits.


　　


Virtualization Technology and network technology, the operation, network, and storage resources can be centralized to form a dynamically allocated resource pool (Resourcepool). Computing resources refers to the overall computing capacity of the mainframe in the computer room, and is configured by the type of the machine. network resources refers to the total bandwidth to the external, the enterprise according to demand, to the network supplier to apply for one or more lines, through the router to centrally manage these lines, and control the internal device and external link bandwidth.  Storage resources are the total capacity of the storage system.


　　


The main consumer of enterprise storage resources is the virtual machine, so the storage system only needs to obtain Vm-ready authentication, guarantee can fully cooperate with the virtual machine operation, can meet the basic requirements of cloud operation.  However, enterprises to import cloud computing, should expect a higher level of cloud-ready storage systems, because cloud computing is not only the virtualization, storage systems must be able to meet the large number of operational units at the same time high-speed access, can dynamically expand capacity without affecting system performance, and has high reliability and resilience.


　　


Enterprises need to further develop the service information architecture. When operations, networks, and storage resources are configured through standard formats and service protocols, the cloud architecture is complete when operating in IaaS mode. The standardized resource service is completely through the network, with the standard protocol, not limited by the actual distance, but limited by the network, namely network bandwidth, network quality and service level. So the private cloud can be built on any site with sufficient network resources or moved into the service provider's room. And the information security problem that enterprise concerns, will turn into the resource allocation problem. Because of these computing, storage, network resources, can be labeled capacity, location, service level and security level. So when a high level of security is required, only high security levels, or resources at a particular location, are selected. And the enterprise's information service demand, through the overall plan, also gradually transforms into the SaaS form, replaces the existing application system.  The SaaS build can be built on either the IaaS or PAAs of the private cloud or the public cloud, or it can operate independently.


　　


resource services are subject to network restrictions, and cloud storage resource services are certainly no exception. This illustrates why cloud backup is currently a handful of successful cloud storage services, because the public cloud stores the last mile of a network link with users, typically a relatively slow and low reliability network.  Under such conditions, even if it is efficient and highly reliable cloud storage, but also suitable for the second line of the backup device, and because the network speed is slow, not practical to backup a large number of data, so the current cloud backup success stories are locked to small and medium-sized enterprises and individuals as the main customers.


　　


But cloud storage services exist not only between Yu Yun and users, but also in the cloud and cloud.  The high-speed network inside the cloud room, or the backbone network between the cloud room, the bandwidth and the quality can be due to the demand of efficiency and reliability.


　　


So the content of the cloud storage services, like the various storage devices currently in use, can be data blocks or files, or media streaming or databases. However, storage devices already have a variety of transport protocols that can be used, such as TCP/IP, FCP, NFS, CIFS, HTTP, FTP, ODBC, JDBC, and so on. But the standard of cloud storage service, although have SNIa and so on non-profit organization to promote, but development is slow, also not popularize. But in practice, because many storage-related protocols are built on Ethernet networks, the main vendors of virtual machines also provide resource management mechanisms and interfaces to configure and manage resources within the cloud; cloud resource scheduling, you can refer to major cloud storage service providers,  such as Amazon or Rackspace specifications.


　　


Cloud computing era, high-density mobile devices, will make cloud services, virtual desktops, cloud storage and cloud backup more common. The storage system will be challenged by a large number of virtual machine i/orequest, and the image data of these VMS will also be stored in the storage system, or at the remote end of the cloud storage. Therefore, efficient, high-capacity, high-quality, scalable storage systems will play an important role. Puan technology continues to create a new generation of cloud-ready storage systems with the view that storage resources must be virtualized, resourced, serviced and automated. For example, Puan's ESVA (Enterprise Extensible Virtualization Architecture) series, with the most advanced hardware design and complete data protection functions, can be from the basic 16 hard drives, expanded to more than 1000, with excellent c/p value, deep customer trust Toshiba Enterprise-Class large-capacity Mustang series of hard Drives,  and Dataprotection,data-tiering,thinprovisioning,de-duplication technology, fully meet the needs of cloud computing environment, and significantly improve operational efficiency and cost savings.
