BUAL 5660 - EXAM 1 QUESTIONS AND ANSWERS WITH COMPLETE SOLUTIONS 5.0 (1 review) Terms in this set (41) Partitioning available resources are divided according to need in the virtual environment. This eliminates physical resources being under or over utilized Isolation each virtual machine is isolated from the others and from the host system, This means that issues affecting one machine will not affect others, keeping data more secure and improving overall performance Encapsulation virtual machines can be designated for specific tasks. This machine could then be used by one or more applications, each of which recognizes the machine, but does not "see" the other Redundant Physical Infrastructure Layer 0. The lowest, or supporting, level in the stack that is comprised of the physical infrastructure that includes hardware, network sytems, wireless and physical communication Security infrastructure Layer 1 Operational Databases Layer 2. hold the day-to-day data for the organization Organizing Data Services and Tools Layer 3. These tools help manage large sets of data by performing capture, validation, and assembly processes Common technologies in this layer are: • A distributed file system - allows access from a number of hosts • Serialization services - a form of transforming data for understanding between applications • Coordination services - help make multiple applications resilient • Extract, transform, load tools - get data ready from its source to its application • Workflow services - keep instructions in a defined order Analytical Data Warehouse Layer 4. Created specifically for the purpose of heavy analysis Focuses on (and must contribute resources to) disparate data, endless new (and often real time) data sources, and reliable content sources Focuses on ease of use and flexibility for the end users Big Data Analytics layer 4.5 Analytics, both traditional and big data, require a supportive architecture Analytics is placed between layers 4 and 5 because they are used in both the data structures(warehouses) and as part of the reporting and visualization processes Tools include those that support: • Reporting and dashboards • Visualization • Analytics and advanced analytics Reporting and Visualization layer 5. Generally, this is about giving the employee what they need when they need it to successfully make decisions Big Data applications layer 6. these encompass anything that fits into the mold - analytics packages, ETL packages, networking support, advanced DSS packages, etc Redundancy the idea that multiple components are able to "step in" when another component fails Performance _ is usually measured by speed. The faster the system, the more expensive. Most existing systems for transactional and operational systems have mid to high latency Availability _ is how frequently the system experiences interruptions. Near 100% is extremely unlikely without significant investment in top infrastructure. Near 100% systems have multiple redundant farms that can come online immediately when another experiences failure Scalability _ includes: - Concurrency issues - processing issues - storage issues. these are relatively easily achieved by using modular approach but this can increase cost
