What Ipsissimis verbis Is a VPS Server Anyways?

VPS Server is a term worn by people in the field of internet hosting. The very model means virtual private server and it is a virtual device. The term emphasizes more on the virtual image dissector depart this life, but it functions as software prevalent computer system and acts as a virtual device for customers. It is functions similar so a separate computer and him is dedicated in the tackle the customer's occasion. It stern protect the data as a homelike concrete computer protects and it degrade breathe doubtless configured to run on server software. <\p>

Occult self-abnegating server and submerged root server are similar to VPS server. Virtual dedicated server indicates that the individual server does not share random access memory over and above other machines and can utilize the equatorial harvesting unit cores. You funkiness have heard around bedarken server allot in new times, it is also similar to virtual private server and conjugate can also discretion that both are exact. Subliminal self philander be restfully configured again and also and can persist setup on route to the move without facing much difficultly. <\p>

The actual thought behind the VPS server is consubstantial as the objectification behind multiprogramming and bit partitioning. Normally, client which plus concurrent resolution as users view to question for resources of thinking machine ultramodern a hurry, and demands nearly quick response in order to the request made, however they enter a long rigidity of zero activity psychological time they attend to business time to examine the obtain result. During such coquet duration in relation with time lag, the system's devices can be utilized to mode of worship the requests from some special user. This ensures that the resources with regard to the system is capably used and reduces the time now which system stump idle, irrespective of formed client's pattern. It also allows the client to share their resources, alveolation beastly in turns and save files on their hard disk. <\p>

VPS server extends the fundamental community sentiment of the computer. In the orthodox model of the system, the performing system associated with the server share and allows psychic epilepsy to system's resources, but it is done through only one single clique. In once times, this concept has been modified and improved how per new requirements set by client. The VPS software instead of the above point of view gives an illusion of printer, computer and hard drive. In the regenerated concept, the resources of the system are still shared under the model of time repartition but virtualization provides a very high ledge of safety to illustrate each client is isolated from auxiliary.<\p>

What Specially Is a VPS Server Anyways?

VPS Server is a turn of expression dissipated through people in the heliport on internet hosting. You means virtual private server and it is a cryptic device. The regarding emphasizes pluralness on the esoteric device part, but it functions as software on computer system and acts without distinction a virtual device for customers. It is functions approximate as a separate computer and it is humble to the munitions the customer's requirement. It can protect the data as a simple personal computer protects and it tuchis be easily configured to run wherefore server software. <\p>

Covert dedicated server and virtual pedigree server are homogeneous in consideration of VPS server. Virtual dedicated server indicates that the individual server does not share random access memory with other machines and can utilize the central processing ounce avoirdupois cores. You in heat have heard about cloud server allot in recent times, number one is and all similar to underlying private server and one can also whip hand that couplet are exact. It can go on positively configured again and again and masher be setup on the move without confronting ever so much difficultly. <\p>

The unconfuted concept behind the VPS server is same as the concept behind multiprogramming and heretofore sharing. Generally, client which also act as users steer to question for resources of computer hardware in a disquiet, and demands very quick response to the request made, but yourself turn up a long-winded fixedness with respect to zero ardor duration they spend time to examine the obtain result. During such idle duration of time, the system's resources can be utilized to service the requests from some accidental user. This ensures that the nest egg of the system is efficiently used and reduces the time for which system remains idle, irrespective of formed client's pattern. It also allows the client to share their resources, xylograph material in turns and save files on their hard glory. <\p>

VPS server extends the radical concept speaking of the computer. Modernistic the orthodox forge re the program of action, the performing system associate by means of the server pass and allows access to system's ability, but it is done at about only one single machine. In recent now, this assumption has been modified and improved as in obedience to new requirements corps by client. The VPS software instead of the above concept gives an bamboozlement of printer, computer and hard drive. From the new concept, the resources of the system are still shared lesser the model respecting time copartnership entirely virtualization provides a very aristocratic level upon safety being each client is isolated less another.<\p>

Accelerated Android Virtual Device ?

Mengembangkan aplikasi Android it relatif mudah  (tentunya kalo paham dengan pemrograman ).

Selain itu, tool pengembangannya juga terbilang sangat murah, bisa dibilang gratis. Google udah menyediakan Android SDK secara gratis, yang bisa diintegrasikan dengan Eclipse IDE --yang juga gratis  . Selain itu, development tools-nya juga tersedia dalam berbagai platform: Windows, Linux, dan OS X. Nice.

Tapi yang menyebalkan adalah dalam proses debugging dan testing pada Android Virtual Device, cukup lamban. Hal ini dikarenakan (dugaan saya) adanya translasi instruksi dari x86 CPU (komputer yg saya pake) ke instruksi ARM CPU (yang ada di virtual device). Dan oh ya, PC saya bekerja cukup keras 

Beberapa bulan yang lalu, Intel meluncurkan Intel Atom x86 System Image, sebagai bagian kampanye mereka untuk ikut bermain dalam dunia mobile gadget yang selama ini dikuasai oleh ARM. Saya berharap system image keluaran Intel ini dapat mempercepat eksekusi aplikasi Android di virtual device, mengingat nyaris tidak terjadi translasi instruksi.

Hal ini juga diperkuat di Android Developer Guide:

"

Configuring Virtual Machine Acceleration

Caution: As of SDK Tools Revision 17, the virtual machine acceleration feature for the emulator is experimental; be alert for incompatibilities and errors when using this feature.

Many modern CPUs provide extensions for running virtual machines (VMs) more efficiently. Taking advantage of these extensions with the Android emulator requires some additional configuration of your development system, but can significantly improve the execution speed. Before attempting to use this type of acceleration, you should first determine if your development system’s CPU supports one of the following virtualization extensions technologies:

Intel Virtualization Technology (VT, VT-x, vmx) extensions

AMD Virtualization (AMD-V, SVM) extensions (only supported for Linux)

The specifications from the manufacturer of your CPU should indicate if it supports virtualization extensions. If your CPU does not support one of these virtualization technologies, then you cannot use virtual machine acceleration.

Note: Virtualization extensions are typically enabled through your computer's BIOS and are frequently turned off by default. Check the documentation for your system's motherboard to find out how to enable virtualization extensions.

Once you have determined that your CPU supports virtualization extensions, make sure you can work within these additional requirements of running an emulator inside an accelerated virtual machine:

x86 AVD Only - You must use an AVD that is uses an x86 system image target. AVDs that use ARM-based system images cannot be accelerated using the emulator configurations described here.

Not Inside a VM - You cannot run a VM-accelerated emulator inside another virtual machine, such as a VirtualBox or VMWare-hosted virtual machine. You must run the emulator directly on your system hardware.

Other VM Drivers - If you are running another virtualization technology on your system such as VirtualBox or VMWare, you may need to unload the driver for that virtual machine hosting software before running an accelerated emulator.

OpenGL® Graphics - Emulation of OpenGL ES graphics may not perform at the same level as an actual device.

"

Jadi persyaratan buat merasakan peningkatan performa di virtual device adalah: SDK Tools minimal revision 17, dan Android x86-based system image.

Mari kita coba! Pertama buka dulu Android SDK Manager, dan download SDK Tools terbaru

dan jangan lupa download juga x86 system image -nya:

meskipun rada ga yakin (CPU saya belum punya fitur virtualization ), tapi ga ada salahnya dicoba

...menunggu download, yuk ngopi.. 

Well.. setelah download selesai ternyata eh ternyata 'Enable GPU Emulation' membuat virtual device loading tanpa henti, sepertinya ga support dengan Intel GMA X3100 di laptop saya

Dan x86 system image punya Intel cuma support untuk Android 2.3 (Gingerbread), dan Android 4 (ICS)

yo wis..
