photo taken by Adrian Cockcroft A year ago I did a talk at re:Invent called Architecture Trends and Topics for 2021 , so I thought it was worth seeing how they played out and updating them for the coming year. I did a few talks on this subject early in the year, and linked this to the sustainability advantages of serverless architectures.

Consistency The topic and concept of consistency is very important when you work with a distributed database like Cassandra. When you’re working with a database which runs on only one server, consistency is a non-issue. Tunable Consistency means that you can set the CL for each read and write request. Comments and thoughts welcome.

Back-end web development predominantly consists of three parts: a server, an application, and a database. The code written by back-end developers is what communicates the database information to the browser. It comprises programming languages, server-side frameworks, operating systems, databases, and APIs.

Source: [link] Cassandra has tunable consistency which means that not only on the database level, you can tune the immediate and eventual consistency of your data per query/operation by setting the read CL (consistency level) and write CL. Comments and thoughts welcome.

From Microservices to Monolith : While Microservices have dominated the discussion of software architecture, there have always been other voices arguing that microservices are too complex, and that monolithic applications are the way to go. Those voices are becoming more vocal. So we need to ask: Is this the year of the monolith?

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.

Considerations for setting the architectural foundations for a fast data platform. 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.

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. Entities are the domain objects (e.g., a Movie or a Shooting Location)?

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.

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.

The applications must be integrated to the surrounding business systems so ideas can be tested and validated in the real world in a controlled manner. Today, a number of cloud-based, auto-scaling systems are easily available, such as AWS Batch. There are countless systems that can perform this task for small DAGs on a single server.

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?
