Amazon elastic cloud

Amazon might be offering virtual cluster building. I have followed “getting started” document and was able to setup one PC instance for a moderate price.
Amazon mozda nudi izagradnju virtualnog grozda: . Slijedio sam „getting started“ dokument i pošlo mi je za rukom pokrenuti jedno ostvarenje PCja, za umjerenu cijenu.
Amazonはビーチャルクラスタを作ることが上げてこられ。私が“getting started”文書を準じたそして一個パソコン例を設定することができた、値段は優しかった。
