Memory Optimizing Temporary Data Structures 

Visualize your data and event 

قیمت گذاری انواع مختلف نمونه­ ماشین آمازون به سه پارامتر وابسته است. اولین مورد سیستم عامل مورد استفاده است. دومین عامل مرکز داده­‌ای است که در آن قرار گرفته و سومین عامل مدت زمانی است که اجرا می­شود. نرخ‌­ها بر مبنای ساعت محاسبه می­شوند. علاوه بر آن مبالغ اضافی نیز بابت موارد زیر اخذ می­شود: 

• میزان داده منتقل شده 
  
• آدرس‌های IP اختصاصی
• استفاده سرور اختصاصی مجازی از فضای ذخیره­سازی بلوکی توسعه پذیر آمازون
  
• استفاده از  توازن بار توسعه پذیر برای دو یا چند سرور 
• سایر ویژگی­های مورد نیاز
