Flexible Cloud Computing In Libraries High Availability Eliminate Downtime

OS-easy Cloud Library Solution
Solution–OS-easy E-VDI for Library
Requirements analysis
 
 Library as important cultural facilities plays an important role in schools. And the computers used in traditional library electronic reading room cost a lot of manpower , material, financial resources and time for the unified deployment, security, and maintenance work, With the continuous expansion of library IT infrastructure, the insufficient IT managers, heavy task, workload, etc contradictions factors are outstanding. Main problems are as follows:
 
Difficult to deploy software
 
Due to numerous computers in library electronic reading room, in order to meet the software changing, improve the electronic reading room using effect, it is the necessary job to deploy and upgrade software for all computers, but it is a difficult job to deploy and upgrade software.
 
Numerous PCs in reading room, difficult maintenance job
 
 
Electronic reading room usually connects to internet through campus network, which is convenient for teachers and students to obtain information, and it is also easy to virus infection. Limited IT managers are exhausted in install operating system, system maintenance, anti-virus, update etc, it is challenge to improve the maintenance model.
 
Unable to provide a dedicated desktop
 
 
Students are unable to obtain a personal desktop for experiment, save personal data, homework, courseware design etc.
 
No fixed PC users
 
First, because the user is different, each computer should install different software for different computer need. In addition, because every computer users are not fixed, software and hardware are easy to be destroyed.
 
Electronic reading room PC performance couldn't catch up with the software update
 
Along with the continuous teaching software renewal, some new software or operating system cannot be installed on the existing computers. Electronic reading room computer should be updated often in a few years.
 
Energy consumption and noisy
 
Traditional PC energy consumption is 250w, the more terminal amount, the more energy consumption, In addition, PC is noisy, can't provide a quiet and comfortable reading environment.
 
 Expensive operation cost
 
due to hardware damage and frequently device changing, the electronic reading room PC should be replaced every 3 to 4 years, high TCO investment and software deployment, updates and patches requires IT managers to update frequently, different computer specifications requires IT staff to troubleshoot onsite, increasing the operating costs.
 
Solution
 
 
Desktop deployment in cloud
 
 
Link clone – fast desktop deployment
 
 
OS-easy E-VDI provides virtual machine link-clone function, which can easily make all kinds of library application desktop template, then IT manager can batch clone virtual machines according to the template with the same configurations, this desktops can be fast distribute to terminals via user name or MAC, it is rapid to deploy desktops environment.

 
A key to update-easily update system and software patches
 
E-VDI supports to edit system template; Install system patches, updates software in the template, using “a key to update" to complete all the virtual machine maintenance, no need to go to terminal site to operate. Student can enter updated desktop which comes from cloud.
 

 
Daily cloud management
 
 
Management on cloud——any device, anywhere, anytime
 
With WEB-based graphical centralized management platform, managers can access the platform on any device has browser, they can execute physical server management, create, delete, and modify virtual machine, install virtual machine system and software; uniformly restrict end user’s computers. Enable to deploy and manage all desktops in office.
 

 
Cloud Management——USB control and terminal management
 
In desktop management platform, you can manage desktop USB permissions, manage terminal devices, and modify PC name, IP, remote startup/shutdown which can simplify library terminal management.

 
Dual desktop mode
 
Teaching desktop, meet the requirements of public reading desktop requirement
"Teaching Desktop" is equivalent to the public reading purpose desktop, administrator can customize the virtual machine restore policy, it can be restored by every time, monthly, weekly, be suit for public computers in library electronic reading room.
 
Personal desktop – meet for assignment, graduation design
 
In "personal desktop", data will be saved permanently in virtual machine. Administrator can assign desktop account for students’ special need like software testing, homework, special design etc...
 
Guarantee cloud security
 
"Dual system" does not affect the teaching when network is disconnected.
 
While using the "virtual desktop", you can also use the local system. The virtual desktop can be used for teacher’s office, browse, library management system etc applications, when network is interrupted, students can use the local system to complete the related work. It supports centralized maintenance, upgrade and other operations to local systems.
 
Flexible dispatch resource-improve resource utilization
 
When system or software upgrade causes the current hardware configuration is unable to meet the software requirements, the resources can be flexible allocated like elastically upgrade memory, CPU, etc., do not need to change the terminal hardware; In addition, "dynamic migration" function can be manually or automatically migrated the virtual machines to other server, "load balancing" function can automatically balance each server utilization to guarantee application running smoothly, meanwhile, maximize hardware use to make sure flexible use hardware resources,.
 
High availability-eliminate downtime
 
Teaching desktop has its restore mode, no matter whatever the users do, it will be restored to the original state to ensure system safety; "virtual machine snapshot" can restore the virtual machine to a specified point; when a single server failed, "High availability" will make virtual machine migrate to other running server automatically (require shared storage); "System backup" can easily complete the whole system data backup, even if the system collapsed, it can restore the data from the backup data.
 
 
Green, energy saving
 
Energy saving–low power consumption
 
It is more energy-saving to compare 15W cloud terminal to 300W traditional PC, the noise is reduced from 50db to10db at the same time, IT devices are more quiet, which achieves green reading. Cloud terminal with low price, free maintenance, low energy consumption advantages, it greatly reduces the computer lab cost from long-term investment prospective.
 
 
Smooth extension, extend device lifecycle
 
Traditional PC’s lifecycle is 3-5 years, cloud desktop life cycle is 5-8 years, it supports smooth upgrade; Only update the server configuration or add new servers without changing terminal devices.
 
 
Project value
 
Library: Construct new era, quiet and Green Library
Use cloud terminal to replace traditional PC, the average power consumption of terminal device is 15w (all-in-one device is 38w), the p
