Private Cloud Trilogy

The first part: it on the flowering


　　


in the initial phase of the private cloud, virtualization is implemented primarily within IT departments, such as developing systems, testing systems, and some IT departments ' own application systems. This stage, the main harvest of enterprises is to reduce costs. The primary object of virtualization is the server, where storage consolidation, increased efficiency, and simplified management are the primary requirements of the store. The proportion of virtualization can reach around 40% of the entire IT system.


　　


Liaoning Mobile First of all, the management center of the data center managed Virtualization transformation, the construction of standardization, automation and virtualization of a new generation of green Enterprise Data Center (Gedc,greenenterprisedatacenter), to achieve efficient IT operations, measurable IT services, Agile IT management, saving it costs. Liaoning Mobile New generation Green Enterprise Data Center (GEDC) project completed, its virtual integration ratio can reach 1:6~8, and obtain the following benefits:


　　


increase it resource delivery level, so that IT resources delivery time will be reduced from the original 1 months to less than 72 hours, significantly improve system reliability, basic clear single point of failure, business recovery time from the hour to the minute level, the reliability of critical business systems can be increased to 99.999% Refinement of resource management, improve resource utilization, so that X86 platform CPU utilization from the average of less than 10% to 55%, storage utilization from about 30% to more than 70%; increase ROI, the total cost of ownership can reduce 30–50%, greatly save investment and energy, obtain significant economic benefits.


　　


adapt to improve it efficiency, simplifies the need for IT management by announcing a number of innovations, such as improved performance and lower costs through a sub LUN-level fast (fully automated tiered storage hierarchy) technology that provides terabytes of read and write access through fast caching technology, and through block compression technology, Reduce up to 50% data footprint; with new emcunisphere management software, CLARiiON and Celerra storage systems can be managed uniformly, with simple, powerful management interfaces, and integration of storage array management and Vmwarevcenter management consoles, CLARiiON and Celerra can be managed in VMware Manager.


　　


Part II: Business Results


　　


On the basis of the first phase, the enterprise will implement the virtualization of the key applications. Critical applications come in, scalability, availability, data protection, and data security become critical issues.


　　


in the traditional IT architecture, scalability is the purchase of a faster server, availability is to build an off-site data center for remote replication. When there is a problem with the local data center, you can go to the offsite data center.


　　


now we have a better way to virtualize servers and storage, centralize all data center resources, and form a pool of resources where virtual machines (data and applications) can move freely between data centers.


　　


How to achieve it?


　　


like a virtual server that transforms physical servers, EMC combines Vplex with other EMC virtual storage technologies such as fast (fully automated storage tiering), triggering a storage-array revolution that shifts from dedicated single machines to efficient, flexible, centralized resources for multiple operating environments, Different geographical share. Federation of Computing and storage resources, enabling virtualization and single resource management for all data centers. Organizations can reconsider their data center policies, regional distributions, numbers, and the role each data center plays in the overall IT environment.


　　


storage virtualization can connect different vendor arrays, combining the capacity of all arrays, and data can be moved from one array to another. Vplex has four versions: Vplexlocal can achieve data movement between different brand arrays in the local data center; Vplexmetro can achieve data movement between different brand arrays within 100 km of the city ; Vplexgeo and Vplexglobal can achieve farther distance data movement.


　　


virtual machines are free to move, which means that when additional resources are needed, they can be used as well, and when a device fails, the business is not interrupted and the virtual machine can automatically move the normal device. Scalability and availability problems are solved.


　　


Virtualization brings new requirements for data protection, such as the need to operate large virtual machine files in bare metal recovery and disaster tolerance, where busy VMware servers may be highly efficient for I/O, and may need to save multiple copies of data protection online. Theinfopro's survey of CIOs shows that the 2010 CIO's top priority in storage is "redesigning the backup architecture."


　　


backup, only need to back up the data not duplicate, remote replication disaster disaster, only need to replicate no duplication of data, greatly save storage, bandwidth and time, improve efficiency.


　　


in data security, the virtual environment will be more secure than the physical environment. Because virtualization and cloud computing are just beginning, people can embed security mechanisms in. Unlike previous it architectures, you need to keep adding security patches.


　　


RSA, a leader in security, can provide system-wide protection for it, secure an alliance of information infrastructure, information, and identity, and provide customers with a standardized virtualized infrastructure to quickly and easily virtualize critical applications.


　　


Part III: IT service


　　


when the vast majority of IT infrastructures and applications are virtualized, one step further, it can be serviced (it-as-a-service), or it may be commercialized. First, the people in charge of IT architecture define the service directory, the customer is in the Self-Service portal to buy the service, the person responsible for application development, based on the customer purchase IT architecture development application, provide to the customer; the person in charge of IT operations plans the amount of the user's actual use of IT infrastructure and charges the customer To make an analogy, just like the power company Power generation, electricity, determine the industrial electricity and electricity standards, we choose to install from the power companies, 380 volts or 220 volts, electric companies according to the electricity standards for us to design electrical appliances, sold to us to use, the power companies according to our monthly electricity charge.


　　

There may be many forms of
IT service. For example, storage service, data protection service.


　　


In summary, the computing, storage, and network resource pools are the three major components of the cloud infrastructure. The relationship between cloud and cloud finally evolved into the integration of resource pools. Information is passed between the cloud and the cloud, and there may be some security mechanisms, cloud operating system information, of course. Thus, as the IT architecture moves towards cloud architecture, the boundaries between the private cloud and the public cloud become increasingly blurred, and the global deployment of applications becomes possible to provide Billenby business continuity, just as we can drink water and breathe air wherever we go.
