Here are five considerations every software architect and developer needs to take into account when setting the architectural foundations for a fast data platform. Are there inherent time relationships in the messages that need to be preserved as they travel across the system? Determine requirements first. At least once?

By Chris Wolfe , Joey Schorr , and Victor Roldán Betancort Introduction The authorization team at Netflix recently sponsored work to add Attribute Based Access Control (ABAC) support to AuthZed’s open source Google Zanzibar inspired authorization system, SpiceDB. This would be a significant departure from its existing policy based system.

CIO: “I wish I could give a definitive answer. CIO: “I hear that the bottleneck is in our legacy systems, or our needing more developers, or issues with our culture. Bottlenecks from internal processes and a dated software architecture severely affected morale. You can’t change the system from within the system.

How do we break a large system into smaller, more manageable modular components? In Domain-Driven Design, a large system is decomposed into bounded contexts , which become natural boundaries in code as microservices and as teams in the organisation. Both a wide and deep knowledge of the business and domain is essential.

This gets tricky at times when collaborating with different companies or communities that use different definitions. To reduce undesired ambiguity in communication consider using the specific definitions. I encounter this problem quite frequently when the word domain is used in the context of business and software architecture.

Domain-Driven Design is an approach to designing systems, usually software, that emphasises creating a common language between domain experts and system builders. However, some concepts in DDD do not have a clear definition and are highly implicit. This definition of a domain is very fuzzy. It can be anything.

Software Architecture. The new category is often called MLOps.

The microservices era has been good for software architecture. 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. I remember when the idea of multiple databases was punishable by death.

Gatekeeper accomplishes its prescribed task by aggregating data from multiple upstream systems, applying some business logic, then producing an output detailing the status of each video in each country.

The key to loose coupling is to understand how the system you are building is going to change, and minimising the cost of those changes. Is there any way it’s possible to predict the future so that our architecture can easily absorb the changes we need to make of it?
