Initially, EC2 used Xen virtualization exclusively. [14] However, on November 6, 2017, Amazon announced [15] the new C5 family of instances that were based on a custom architecture around the KVM hypervisor, called Nitro. [16] [17] Each virtual machine, called an "instance", functions as a virtual private server. Amazon sizes instances based on ...
An Amazon Machine Image (AMI) is a special type of virtual appliance that is used to create a virtual machine within the Amazon Elastic Compute Cloud (EC2). It serves as the basic unit of deployment for services delivered using EC2.
In the field of software architecture, many empirical studies have shown the following common benefits and drawbacks from adopting a software reference architecture within organizations: (a) improvement of the interoperability of the software systems by establishing a standard solution and common mechanisms for information exchange; (b ...
According to Forrester Research, solution architecture is one of the key components by which Enterprise Architecture delivers value to the organization. It entails artifacts such as a solution business context, a solution vision and requirements, solution options (e.g. through RFIs, RFPs or prototype development) and an agreed optimal solution with build and implementation plans ("road-map").
Enterprise architecture regards the enterprise as a large and complex system or system of systems. [3] To manage the scale and complexity of this system, an architectural framework provides tools and approaches that help architects abstract from the level of detail at which builders work, to bring enterprise design tasks into focus and produce valuable architecture description documentation.
Architecture, in the context of software systems, is roughly divided into categories, primarily software architecture, network architecture, and systems architecture. Within each of these categories, there is a tangible but fuzzy distinction between architecture and design.
Cloud computing architecture refers to the components and subcomponents required for cloud computing.These components typically consist of a front end platform (fat client, thin client, mobile), back end platforms (servers, storage), a cloud based delivery, and a network (Internet, Intranet, Intercloud).
Amazon Elastic Block Store (EBS) provides raw block-level storage that can be attached to Amazon EC2 instances and is used by Amazon Relational Database Service (RDS). [1] It is one of the two block-storage options offered by AWS, with the other being the EC2 Instance Store. [2] Amazon EBS provides a range of options for storage performance and ...
