415:. These skills include an understanding of application modularization/distribution, integration, high availability, and scalability patterns, technology and trends. Increasingly, an understanding of application containers, serverless computing, storage, data and analytics, and other cloud-related technology and services are required application architect skills. While a software background is a great foundation for an application architect, programming and software design are not skills required of an application architect (these are actually skills for a Software Architect, who is a leader on the 450:, systems, tools, regulations and structure and how they interrelate to provide products and services that create value for customers, consumers and key stakeholders. Understanding of how the value create for customers, consumers and key stakeholders aligns with organization's vision, business, culture, value proposition, brand promise and strategic imperatives. Understanding of organization's past and present achievements and shortcomings to assess strengths, weaknesses, opportunities and risks in relation to the competitive environment. 33: 396:(behavioural pattern): An application integration pattern for exchanging data where the application requests data from another application and waits for a reply containing the requested data. This is the most prominent example of a synchronous pattern, in contrast to the asynchronous processing referred to in previous pattern descriptions. 474:, ensures that all hardware and software comply with baseline requirements and standards before being integrated into the business environment, understands and is able to develop technical standards and procedures to facilitate the use of new technologies, develops useful guidelines for using and applying new technologies. 431:

An applications architect is a master of everything application-specific in an organization. An applications architect provides strategic guidelines to the applications maintenance teams by understanding all the applications from the following perspectives:

The above analysis will point out applications that need a range of changes – from change in deployment strategy for fragmented applications to a total replacement for applications at the end of their technology or functionality lifecycle.

Application patterns can describe structural (deployment/distribution-related) or behavioural (process flow or interaction/integration-related) characteristics and an application architecture may leverage one or a mix of patterns.

Many organizations do not have documentation discipline and hence lack detailed business process flows and system process flows. One may have to start an initiative to put those in place first.

Understand the system process flow of the primary business processes. It gives a clear picture of the functionality map and the applications footprint of various applications across the map.

Despite the plethora of patterns that have been published, there are relatively few patterns that can be thought of as "industry standard". Some of the best-known of these include:
