However, telematics architectures face challenges in responding to telemetry in real time. Current Telematics Architecture. Every few seconds, the application servers collect batches of snapshots and write them to the database where they can be queried by dispatchers managing the fleet. Challenges for Current Architectures.

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.

I spend a large amount of time translating software requirements into schema and queries. Every time we interact with software that displays a table, we can expect the columns to be sortable like this: Sort-By-Colunn is a great pattern when all the data can fit in the browser.

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. The language, practices, and tools of cloud native architecture are prominent in Velocity Berlin proposals. Quantum computers of that scale are still a long way off.

At one point, more than 30 developers were working on it, and it had well over 300 database tables. Leveraging Hexagonal Architecture We needed to support the ability to swap data sources without impacting business logic , so we knew we needed to keep them decoupled. The dependency graph in Hexagonal Architecture goes inward.

As the pace of business quickens, software development has adapted. Increasingly, teams release software features more quickly to accommodate customer needs. As a result, organizations are weighing microservices vs. monolithic architecture to improve software delivery speed and quality. What is monolithic architecture?

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.

To gain all those benefits, you are trading off immediate consistency for eventual consistency. Comments and thoughts welcome.

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.

Another advantage of field measurements is that they match the approach taken by Google in order to collect performance data into the CrUX database.

Building general purpose architectures has always been hard; there are often so many conflicting requirements that you cannot derive an architecture that will serve all, so we have often ended up focusing on one side of the requirements that allow you to serve that area really well.

Loosely-coupled teams enabled by loosely-coupled software architecture is one of the strongest predictors of continuous delivery performance and organizational scaling. With loosely-coupled architectures we can invest more granularly where payback is greatest. Diligently-crafted boundaries give us strategic-flexibility.

In software, reacting to unforeseen circumstances in real-time is not possible. The gap between defining business requirements and translating them into software needs to be minimised in order to prevent this category of problems. In the software system, we need to decide the business transaction boundaries aka DDD Aggregates.
