I did a few talks on this subject early in the year, and linked this to the sustainability advantages of serverless architectures. The need for systems to be resilient is still increasing, and chaos engineering tools and techniques are developing as a key way to validate that resilience is working as designed.

The backlash against the backlash against Open Source : Over the past decade, a number of corporate software projects have changed from an open source license, such as Apache, to one of a number of “business source” licenses. These licenses vary, but typically restrict users from competing with the project’s vendor.

Data Consistency in Apache Cassandra — Part 3 was originally published in Software Architecture on Medium, where people are continuing the conversation by highlighting and responding to this story. To gain all those benefits, you are trading off immediate consistency for eventual consistency. Comments and thoughts welcome.

One of the biggest time costs in software development is understanding how a system works. Systems are getting more complex yet our ability to understand them doesn’t seem to be growing at the same rate. As we continuously develop software systems, the complexity slowly increases and we don’t fully realise it.

Most of what we do on our computers—fancy graphics, email, databases, building websites, data analysis, digital signal processing—can’t be done with quantum computing. SRE is a very different way of thinking about software development. Europe and the United States are different regions —and it isn’t just the metric system.

Google was among the pioneers that created “web scale” architectures to analyze the massive data sets that resulted from “crawling” the web that gave birth to Apache Hadoop, MapReduce, and NoSQL databases. Are there inherent time relationships in the messages that need to be preserved as they travel across the system?

Technology systems are difficult to wrangle. Our systems grow in accidental complexity and complication over time. Likewise, the term "architect" didn't enter popular usage to describe a role in the software field until the late 1990s. Architecture begins when someone has a nontrivial problem to be solved.

You need an “abtest” database service. In a small system this may be a table in a central relational database, but it’s best setup as a NoSQL data source using something like Amazon DynamoDB or Apache Cassandra, with a caching client library or at large scale a microservice data access layer.

We had an interesting challenge on our hands: we needed to build the core of our app from scratch, but we also needed data that existed in many different systems. At one point, more than 30 developers were working on it, and it had well over 300 database tables. We treat it as an input for our system.

The microservices era has been good for software architecture. I remember when the idea of multiple databases was punishable by death. A domain service builds on the basic definition of a microservice: it’s a loosely-coupled, independently deployable element of software architecture which is owned by a single team.

Organisations maximising the advantages provided by microservices tend to be organisations which view microservices not just as a technical tool, but a sociotechnical tool.The way software systems are shaped determines the communication paths and the coupling between development teams. As a consequence, we also have subservient teams?
