The Lifehacker's Guide to Software Architecture

Your primary role as an architect isn't to find silver bullets. It's to identify the least painful option on the table.

#1about 3 minutes

Beware the faith healer and embrace trade-offs

Every technology or architectural decision comes with downsides, so an architect's job is to identify and choose the least painful option.

#2about 2 minutes

Understanding the trade-offs of using message queues

Message queues can manage fluctuating workloads and decouple services, but they introduce trade-offs like message backlogs and monitoring complexity.

#3about 3 minutes

Applying the divide and conquer principle to monoliths

Breaking down a monolith into independent services can maintain a cleaner architecture over time but introduces significant operational complexity.

#4about 1 minute

Using design patterns as a common language

Design patterns like those from the Gang of Four provide a shared vocabulary to communicate complex architectural concepts effectively.

#5about 6 minutes

Achieving loose coupling with asynchronous patterns

Use asynchronous patterns like queues and topics to reduce temporal, availability, and location dependencies between services in a distributed system.

#6about 7 minutes

Designing for failure with retries and replays

Manage inevitable system failures by implementing patterns like dead letter queues for retries, understanding the scope of deduplication, and using archive-and-replay for disaster recovery.

Preparing for success by architecting for flexibility

Ensure your system can handle growth from a hundred to millions of users by building flexibility into all layers, not just compute.

#8about 1 minute

Don't reinvent the wheel, focus on your business

Avoid building undifferentiated infrastructure and instead leverage existing tools and industry standards to focus on features that are unique to your business.
