Sustainable Architecture Principles and Goals

Creating and maintaining software architecture that is sustainable over time is a challenge for software architects and developers. Software architects are used to meeting each requirement, providing each feature, and planning each system component one at a time with the larger software architecture, including the design and completion of the architectural design before implementation begins. includes doing. Alternatively, teams can produce contingency architecture, where development teams begin by providing functionality and with a little advance planning allow architectural designs to emerge. Unfortunately, none of those methods are consistently successful in providing sustainable architecture.

Sustainable Architecture Principles

For a “persistent architecture”, it’s all about making the right decisions and using the appropriate tools to support continuous delivery, continuous integration, and continuous testing. “Sustainable architecture” is an approach based on a toolbox – not a formal process.

It is based on the following principles that describe how software architects can continually elaborate software architecture in today’s world of Agile, DevOps and Cloud:

  • Focus on quality characteristics, not functional requirements. Quality attribute requirements drive the architecture.
  • Take advantage of the “power of small” – architect for change. Large, monolithic, tightly coupled components are difficult to replace. Instead, take advantage of smaller, loosely coupled software elements.
  • Architect Products; Develop from projects to products. Architectural products are more efficient than creating point to point solutions for projects and keep the team focused on their customers.
  • Delay design decisions unless they are absolutely necessary. Design architecture based on facts, not guesses. There’s no point in designing and implementing capabilities that may never be used – it’s a waste of time and resources.
  • Architect for construction, testing, deployment and operation. Most architecture methodologies focus exclusively on software manufacturing activities, but architects and engineers must also be concerned about testing, deploying, and operating in order to support continuous delivery.
  • Model the organization of your teams according to the design of the system you are working on. The way teams are organized drives the architecture and design of the systems they are working on.

These principles provide a useful model but are not prescriptive. They are complemented by the following four essential activities:

  1. “Focus on quality attributes, which are the key cross-cutting requirements that good architecture must address.
  2. Driving architectural decisions, which are the primary unit of work for architectural activities.
  3. Know your technical debt, the understanding and management of which is critical to sustainable architecture.
  4. Implement a feedback loop, which enables us to iterate through the software development lifecycle and understand the impact of architectural decisions. Automation is a key aspect of an effective feedback loop.

In addition, continuous architecture includes an architectural “toolbox” that includes a set of proven tools, such as decision logs, utility trees, and architectural strategy. Software architects and engineers can extend this toolbox as needed by adding relevant tools to their contexts.

Sustainable architecture starts with your problems, rather than promoting a general organizational or architectural model. It drives the transition from project to product and leverages the power of modern software engineering practices. It is really open.

In the context of Continuous Delivery, Continuous Architecture aims to accelerate the software development and delivery process by systematically applying an architectural perspective and discipline consistently throughout the process.

Here’s how to bring an architectural perspective into the overall process, following five key components of that process:

• Continuous Feedback and Monitoring

• Continuous Integration (CI)

• Continuous Release and Deployment

• Continuous Testing

• Hybrid Cloud Deployment

Sustainable architecture also operates in two dimensions, time and scale. The time dimension describes how software architects enable architectural practices in a world of increasingly rapid delivery cycles. However the scale dimension reflects the level at which software architects are working. Sustainable architectural principles apply consistently to all scales, but the level of focus and the equipment used can vary.

One of the major advantages of Continuous Architecture is that it is driven by feedback; In fact, the team actively seeks feedback from development teams, test teams, DevOps teams, and their business partners. They use this feedback to continuously test the architecture and control the development of the architecture based on the data. This data is collected through multiple channels, for example, “prototyping”, A/B testing, feedback loops from continuous testing, manual review, automated code inspection, or any number of approaches that provide actual feedback on architectural properties. Huh.

Sustainable Architecture Goals

• Creating an architecture that can evolve with applications, that is testable, that can respond to feedback and is truly driven by feedback

• To make enterprise architecture a reality

• Solutions to make the structure sustainable

• To create real-world, actionable, useful strategies

Software architects create long-term products, not just project solutions. Software architects tend to treat architecture activities as a runway after the life of the product (as it passes through various stages: from cradle to grave).

Software architects have to make decisions, design new features, and rethink/rework what they have done given the new context in which they are. The design needs to be robust for future changes.

Software architects build products from a holistic perspective. There are two different but complementary ideas behind this. First, software architects look at architecture from a full-stack perspective, considering the products of all the different layers: infrastructure, networks, middleware, applications, and urbanism. Meanwhile, software architects also need to make sure the product fits well into the system. Here software architects focus on the integration strategy with other system products that have to be communicated with.

Software architects validate and validate architecture by implementing it, not by validating documents. Powerpoint slides, and Archimet diagrams do not go into production. Does the code developed by their squad. And the sooner the better.

Teams implementing a persistent architecture at the individual application level may notice that this enables a more sustainable delivery model and platform that is more resilient to future changes. Companies that leverage continuous architecture at the enterprise level can observe an increased efficiency in delivering solutions, a healthier ecosystem of common platforms, and increased knowledge sharing.

If you are interested in software architecture, I highly recommend you to attend the Global Software Architecture Summit, which will take place in Barcelona (October, 3-4), where you will talk about Continuous Architecture with leading software architects. Will get a chance to do

And if you have a software architecture project in mind, do let us know, at Apiumhub we are the experts in this area!
