The jobs-to-be-done framework is an approach to developing products based on understanding both the customer’s specific goal or “job,” and the thought processes that would lead that customer to “hire” a product to complete the job. When using this framework, a product team attempts to discover what its users are…

Many applications use JSON Web Tokens (JWT) to allow the client to indicate its identity for further exchange after authentication. From JWT.IO: JSON Web Token (JWT) is an open standard (RFC 7519) that defines a compact and self-contained way for securely transmitting information between parties as a JSON object. This information can…

Software architecture has a big role to play in the costs and impacts of change across all four of the lenses we’ve described. But another part of the story is the way that changes are applied. Microservices architectures, cloud infrastructures, and DevOps practices have enabled practices that are a huge…

The following guidelines are fairly opinionated and are based on the experience of the authors of this book. We recommend that you use these guidelines as a starting point. After you have had experience building services with our guidelines, we expect that you may consider modifying some of them to…

At first, you should read this article: https://abbasimhoseinit.medium.com/domain-driven-design-and-microservice-boundaries-63e7253e41b6 Domain-Driven Design is a powerful methodology for analyzing both the whole system-level (called “strategic” in DDD) as well as the in-depth (called “tactical”) composition of your large, complex systems. We have also seen that DDD analysis can help us identify fairly autonomous…

At the onset of figuring out microservices design best practices, Sam Newman introduced some foundational ground rules in his book Building Microservices (O’Reilly). He suggested that when drawing service boundaries, we should strive for such a design that the resulting services are: Loosely coupled Services should be fairly unaware and independent of…

What is Remote Procedure Call (RPC)? Remote Procedure Call is a software communication protocol that one program can use to request a service from a program located in another computer on a network without having to understand the network’s details. RPC is used to call other processes on the remote systems like a local system. …

APIs and microservices do indeed have a lot in common. Microservices are capabilities exposed via standard network protocols, most commonly HTTP. But capabilities exposed as HTTP endpoints had been known as web APIs, way before the coining of the term microservices. So are the two essentially the same thing? Are…
