Broadly speaking, the external architecture of microservices is anything outside the microservices infrastructure. These include the clients trying to communicate with the microservices and the services the microservices are trying to reach out to that are hosted by 3rd party organizations. When microservices are communicating with external architecture components we…

The outer architecture is the space between microservices and is by far the most difficult part. Microservices is a tradeoff from inner complexity to outer complexity. Think of it as anything that is not the responsibility of an individual microservice team. The outer architecture includes all of the infrastructures on…

The generally accepted practice when building your MSA is to focus on how you would scope out a service that provides a single-function rather than the size. The inner architecture typically addresses the implementation of the microservices themselves. …

Microservice architecture (MSA) is a method of developing software applications by building them as collections of independent and modular services. Microservices can be deployed to create a more flexible digital architecture. Smaller teams can work separately on these microservices and share them with other application developers via APIs for reuse…

A no-nonsense, fast-paced Java interview preparation guide for humans Part 4: Database SQL Key Concepts SQL: SQL(Structured Query Language) is a standard language for accessing and manipulating databases. RDBMS: RDBMS(Relational Database Management System) is the basis for SQL, and for all modern database systems. The data in RDBMS is stored in database objects called tables. Every table is broken up into smaller entities called fields. A record, also called a row, is each individual entry that exists in a table.
