# Awesome Architecture ![Awesome](https://awesome.re/badge.svg)



This document starts with a list of concepts, mindset and foundations, followed by [jobs-to-be-done](https://strategyn.com/jobs-to-be-done/).



## Concepts

* [Application Lifecycle Management (ALM)](https://aws.amazon.com/what-is/application-lifecycle-management/)

* [Architecturally significant requirements](https://en.wikipedia.org/wiki/Architecturally_significant_requirements) criteria: business value/risk, stakeholder concern, quality level, external dependencies, cross-cutting, first-of-a-kind, source of problems on past projects.

* [Architectural decision records (ADRs)](https://docs.aws.amazon.com/prescriptive-guidance/latest/architectural-decision-records/appendix.html): Records that support team alignment, document strategic directions for a project or product, and reduce recurring and time-consuming decision-making efforts.

* [Continuous Configuration](https://www.allthingsdistributed.com/2021/08/continuous-configuration-on-aws.html) values often fall into two groups: those that modify operational behavior of an application—such as throttling, limits, connection limits, or logging verbosity—and those that control FAC (Feature Access Control), including feature flags, A/B testing, and user allow/deny lists.

* [Coupling](https://architectelevator.com/cloud/cloud-decoupling-cost/): Coupling describes the independent variability of connected systems, i.e., whether a change in System A has an effect on System B. If it does, A and B are coupled.

* Coupling facets ([video](https://youtu.be/w9a7eI6BlVc?t=1487), [post](https://www.enterpriseintegrationpatterns.com/ramblings/coupling_facets.html)): 1/ Technology (Java vs. C++, Kubernetes, PostgreSQL) 2/ Location (IP addresses, DNS) 3/ Data Format (Binary, XML, JSON, protobuf, Avro) 4/ Data Type (int16, int32, string, UTF-8, null, empty) 5/ Semantic (Name, Middlename, ZIP) 6/ Temporal (sync, async) 7/ Interaction Style (messaging, RPC, query, GraphQL) 8/ Conversation (pagination, caching, retries).

* Declarative provisioning not equal to Declarative language ([video](https://www.youtube.com/watch?v=ttJAIQf7cTw&t=2077s), [slides](https://d1.awsstatic.com/events/reinvent/2021/Building_modern_cloud_applications_Think_integration_API308%20.pdf#page=42))

* [Event-Driven Architecture](https://www.youtube.com/watch?v=STKCRSUsyP0&feature=share) patterns: 1/ Event Notification 2/ Event-carried State Transfer 3/ Event Sourcing 4/ Command and Query Responsibility Segregation.

* [Feature Flags](https://launchdarkly.com/blog/what-are-feature-flags/)

* [GitOps](https://opengitops.dev/): 1/ Declarative 2/ Versioned and Immutable 3/ Pulled Automatically 4/ Continuously Reconciled.

* [Platform](https://youtu.be/eMrmAn3bYiI?t=1524): a set of standardized elements that provide value but do not presuppose all problems.

* [SaaS Architecture Fundamentals](https://docs.aws.amazon.com/whitepapers/latest/saas-architecture-fundamentals/saas-architecture-fundamentals.html)

* [Software Boundaries or "Fracture Planes"](https://blog.matthewskelton.net/about/): 1/ Business Domain Bounded Context 2/ Regulatory Compliance 3/ Change Cadence 4/ Team Location 5/ Risk 6/ Performance Isolation 7/ Technology 8/ User Personas.

* [Software delivery performance four key metrics](https://www.thoughtworks.com/radar/techniques/four-key-metrics): 1/ Cycle Time (Change Lead Time) 2/ Deployment Frequency 3/ Change Failure Rate (CFR) 4/ Mean Time to Recovery (MTTR).

* [Frugal Architecture](https://www.thefrugalarchitect.com/): 1/ Make Cost a Non-functional Requirement 2/ Systems that Last Align Cost to Business 3/ Architecting is a Series of Trade-offs 4/ Unobserved Systems Lead to Unknown Costs 5/ Cost Aware Architectures Implement Cost Controls 6/ Cost Optimization is Incremental 7/ Unchallenged Success Leads to Assumptions.



## Mindset

* You won’t be agile by focusing on agile frameworks. Agility requires changing everything we do, beginning with engineering our systems for lower delivery friction. ([Bryan Finster](https://www.infoq.com/articles/replace-process-dogma-engineering/))

* Don’t look for a great Idea, find a good Problem to solve. (Someone)

* Abstraction in the cloud: a service with higher-level vocabulary that shields from the complexity, security and operations of the underlying implementation ([Alex Pulver](https://www.linkedin.com/in/alexpulver/))

* Infrastructure libraries provide compositions, not abstractions, because consumers own security and operations of the underlying implementation. ([Alex Pulver](https://www.linkedin.com/in/alexpulver/))

* Drawing architecture diagrams makes unclear things clear and clear things obvious. ([Alex Pulver](https://www.linkedin.com/in/alexpulver/))

* A system is only evolvable if you can easily understand it and you can safely change it. ([Rebecca Parsons](https://www.infoq.com/podcasts/evolutionary-architecture-evolution/))

* Cloud automation tools like AWS CDK and Pulumi allow you to implement application’s architecture and domain logic using the same programming language. ([Alex Pulver](https://www.linkedin.com/in/alexpulver/))
