AWS Lambda is an event-driven, serverless Function as a Service (FaaS) provided by Amazon as a part of Amazon Web Services. It is designed to enable developers to run code without provisioning or managing servers. It executes code in response to events and automatically manages the computing resources required by that code. It was introduced on ...
This feature can provide rich functionality for desktop application and web applications. One note of caution would be to consider the overhead for high-transaction web-based applications. n-Level undo capability will require storing the previous state of an application generally accessed by reflection.
N-tier architecture is a good fit for small and simple applications because of its simplicity and low-cost. Also, it can be a good starting point when architectural requirements are not clear yet. [1] [2] A three-tier architecture is typically composed of a presentation tier, a logic tier, and a data tier.
Event-driven architecture (EDA) is a software architecture paradigm concerning the production and detection of events. Event-driven architectures are evolutionary in nature and provide a high degree of fault tolerance , performance, and scalability .
An application server is a server that hosts applications [1] or software that delivers a business application through a communication protocol. [2] For a typical web application, the application server sits behind the web servers. An application server framework is a service layer model.
The CORBA specification (and thus this figure) leaves various aspects of distributed system to the application to define including object lifetimes (although reference counting semantics are available to applications), redundancy/fail-over, memory management, dynamic load balancing, and application-oriented models such as the separation between ...
Eucalyptus Compatibility with Amazon Web Services. Organizations can use or reuse AWS-compatible tools, images, and scripts to manage their own on-premises infrastructure as a service (IaaS) environments. The AWS API is implemented on top of Eucalyptus, so tools in the cloud ecosystem that can communicate with AWS can use the same API with ...
The C4 model documents the architecture of a software system, by showing multiple points of view [5] that explain the decomposition of a system into containers and components, the relationship between these elements, and, where appropriate, the relation with its users. [3] The viewpoints are organized according to their hierarchical level: [2] [3]
