Microservices design patterns are software design patterns that generate 𝐫𝐞𝐮𝐬𝐚𝐛𝐥𝐞 𝐚𝐮𝐭𝐨𝐧𝐨𝐦𝐨𝐮𝐬 services. The aim is to allow developers who use microservices to accelerate application releases and deploy each microservice 𝐢𝐧𝐝𝐞𝐩𝐞𝐧𝐝𝐞𝐧𝐭𝐥𝐲 if needed. Different microservices patterns each have their advantages and drawbacks. Each service is fully 𝐚𝐮𝐭𝐨𝐧𝐨𝐦𝐨𝐮𝐬 and full-stack. Changing a service implementation won’t impact other[...]

The diagram below shows the process. Note that the architectures for different databases are different, the diagram demonstrates some common designs. Step 1 – A SQL statement is sent to the database via a transport layer protocol (e.g.TCP). Step 2 – The SQL statement is sent to the command parser, where it goes through syntactic[...]

The success of a software application often hinges on the choice of the right databases. As developers, we’re faced with a vast array of database options. It is crucial for us to understand the differences between these options and how to select the ones that best align with our project’s requirements. A complex application usually[...]
