  • Tính toán và lưu trữ dạng “đám mây” chuyển các tài nguyên vật lý (như bộ vi xử lý và thiết bị lưu trữ) thành các tài nguyên mở rộng được và chia sẻ được trên Internet (tính toán và lưu trữ dưới dạng các “dịch vụ”). Mặc dù không phải là một khái niệm mới nhưng ảo hóa (virtualization) khiến cloud computing trở nên dễ mở rộng và hiệu quả hơn nhiều thông qua việc chia sẻ các hệ vật lý với sự ảo hóa server. Cloud computing cho phép người dùng tiếp cận đến các tài nguyên tính...

  • Cloud computing là gì? Để kiểm tra phản ứng nhanh nhạy của các ứng viên xin việc, Google chỉ cần đặt ra một câu hỏi tưởng chừng đơn giản: "Bạn sẽ làm gì nếu dữ liệu hiện có tăng gấp 1.000 lần?". Nếu người xin việc bê nguyên những công thức được "nhồi sọ" ở trường vào tình huống này, họ sẽ biến máy chủ thành những chú ốc sên khi nhân lượng video, ảnh, bản đồ, thông tin mua sắm... lên 1.000. Bởi thế, để tìm được chỗ đứng ở Google, họ cần học cách làm việc và cả ước mơ...

  • Consolidation of applications in cloud computing environments presents a significant opportunity for energy optimization. As a first step toward enabling energy efficient consolidation, we study the inter-relationships between energy consumption, resource utilization, and performance of consolidated workloads. The study reveals the energy performance trade-offs for consolidation and shows that optimal operating points exist. We model the consolidation problem as a modified bin packing problem and illustrate it with an example.

  • In this study, our purpose is to distribute interfaces in cloud computing environment in a way that they are useful to optimize resource allocation and to reach the main purpose of this research; that is, to reduce energy consumption. By creating an abstract layer on all physical resources, resources can be managed dynamically by the help of virtualization. Selecting an appropriate and efficient algorithm is required for resource allocation due to dynamic resources and various user requests in cloud technology to increase efficiency.
