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").
The software engineering community uses an architecture description language as a computer language to create a description of a software architecture. In the case of a so-called technical architecture , the architecture must be communicated to software developers; a functional architecture is communicated to various stakeholders and users.
A software design description (a.k.a. software design document or SDD; just design document; also Software Design Specification) is a representation of a software design that is to be used for recording design information, addressing various design concerns, and communicating that information to the design’s stakeholders.

Second, reflected in work of CMU and elsewhere, the notion that architecture was the high level organization of a system at run-time and that architecture should be described in terms of their components and connectors: "the architecture of a software system defines that system in terms of computational components and interactions among those ...
The SLA is the entire agreement that specifies what service is to be provided, how it is supported, times, locations, costs, performance, and responsibilities of the parties involved. SLOs are specific measurable characteristics of the SLA such as availability, throughput, frequency, response time, or quality.
Software Architecture Style refers to a high-level structural organization that defines the overall system organization, specifying how components are organized, how they interact, and the constraints on those interactions. Architecture styles typically include a vocabulary of component and connector types, as well as semantic models for ...
