Cell-Based Architecture Adoption Guidelines

The challenges in building modern, reliable, and understandable distributed systems continue to grow, and cell-based architecture is a valuable way to accept, isolate, and stay reliable in the face of failures. Organizations must ensure that the cell-based architecture is the right fit for them and that the migration will not cause more problems than it solves.

Adaptive Responses to Resiliently Handle Hard Problems in Software Operations

As engineers move into more senior positions such as Staff Engineer, Architect, or Sr Tech Lead roles, their knowledge and experience is often applied across the system. This expertise is increasingly needed for handling novel problems or designing innovative solutions to complex problems. This article discusses strategies for approaching your role as a senior member of your organization.

Taking Advantage of Cell-Based Architectures to Build Resilient and Fault-Tolerant Systems

Cell-based architectures offer a robust approach to building resilient systems. They achieve this through the core principles of isolation, autonomy, and replication. Each cell manages its resources and makes decisions autonomously. Observability for cell-based architecture requires a tailored approach to address the unique challenges and opportunities presented by this distributed system design.

How Cell-Based Architecture Enhances Modern Distributed Systems

Cell-based architecture has emerged as a response to many challenges associated with distributed systems. It employs the bulkhead pattern to isolate failures to a fraction of the affected infrastructure footprint and prevent widespread impact. Cells can also help organize large architectures into domain-bound deployment and delivery units, which provides essential sociotechnical benefits.

Prepare to Be Unprepared: Investing in Capacity to Adapt to Surprises in Software-Reliant Businesses

Incidents are often perceived as extraordinary aberrations, unconnected to "normal" work. For over twenty years, the field of Resilience Engineering has aimed at flipping this approach around — by understanding what makes incidents so rare (relative to when and how they do not happen) and so minor (relative to how much worse they can be) and deliberately enhancing what makes that possible.

Generative AI and Organizational Resilience

Generative AI will profoundly transform communication and information sharing over the next decade, but the change will be uneven across industries and roles. Organizations should empower workers to use AI augmentation thoughtfully, while building literacy on capabilities and limits. A balanced, conscientious integration, using iterations and customer feedback, will produce the best outcomes.

Orchestrating Resilience Building Modern Asynchronous Systems

In this article, we will discuss what problems we had to solve at Twilio to efficiently build a resilient and scalable asynchronous system to handle a complex workflow and the advantages we got from adopting a Workflow Orchestration solution, including abstracting away state management and out-of-the-box support for retries, observability, and audibility.

The Incident Lifecycle: How a Culture of Resilience Can Help You Accomplish Your Goals

Don’t get stuck with overwhelmed systems that can cause an outage, like what happened with Taylor Swift concert tickets. Build organizational resilience to incidents through improved coordination and communication during the response, and blameless reviews, root cause analysis, and insightful communication afterward to enable meaningful change.

Write More, Talk Less: Building Organizational Resilience through Documentation and InnerSource

Better documentation and knowledge sharing creates transparency that aids onboarding, prevents turnover disruption, and withstands reorganizations. Different practices can help, such as communicating asynchronously, creating incentives for documentation, making docs discoverable, understanding team members' preferences, and providing dedicated writing time. And maybe InnerSource can help too.
