A database shard, or simply a shard, is a horizontal partition of data in a database or search engine. Each shard is held on a separate database server instance, to spread load. Some data within a database remains present in all shards, [a] but some appear only in a single shard. Each shard (or server) acts as the single source for this subset ...
Webscale is a computer architectural approach that brings the capabilities of large-scale cloud computing companies into enterprise data centers. [ 4 ] In distributed systems , there are several definitions according to the authors, some considering the concepts of scalability a sub-part of elasticity , others as being distinct.
Cloud gaming, sometimes called gaming on demand or game streaming, is a type of online gaming that runs video games on remote servers and streams the game's output (video, sound, etc) directly to a user's device, or more colloquially, playing a game remotely from a cloud. It contrasts with traditional means of gaming, wherein a game is run ...
Autoscaling, also spelled auto scaling or auto-scaling, and sometimes also called automatic scaling, is a method used in cloud computing that dynamically adjusts the amount of computational resources in a server farm - typically measured by the number of active servers - automatically based on the load on the farm. For example, the number of ...
A variety of approaches are used to scale beyond the limits of a single computer. HP Enterprise's NonStop SQL uses the shared nothing architecture in which neither data nor memory are shared across server boundaries. A coordinator routes database requests to the correct server. This architecture provides near-linear scalability.
Vertical scaling, also known as scaling up, is the process of replacing a component with a device that is generally more powerful or improved. For example, replacing a processor with a faster one. Horizontal scaling, also known as scaling out is setting up another server for example to run in parallel with the original so they share the workload.
A larger horizontal resolution directly increases the horizontal field of view, and a larger vertical resolution increases the vertical field of view. [11] Vert-(vertical minus) is a scaling method used by some games that support a wide variety of resolutions. In Vert- games, as the aspect ratio widens, the vertical component of the field of ...
The most widespread use of multitier architecture is the three-tier architecture. N-tier application architecture provides a model by which developers can create flexible and reusable applications. By segregating an application into tiers, developers acquire the option of modifying or adding a specific tier, instead of reworking the entire ...
