What is dry in microservices architecture most suitable answer is?

While the DORY is more appropriate for the common code across microservices, the DRY is more suitable for the code within a single microservice. Encapsulate the repeated code inside reusable classes or functions as appropriate within a microservice.

What are the three main service patterns?

While there are literally dozens of ways to implement a microservices architecture pattern, three main topologies stand out as the most common and popular: the API REST-based topology, application REST-based topology, and the centralized messaging topology.

Which design pattern in microservices architecture follows DRY principle?

The Aggregate Design Pattern is based on the DRY principle. Based on this principle, you can abstract the logic into a composite microservices and aggregate that particular business logic into one service.

What is DRY rule?

“Don’t repeat yourself” (DRY, or sometimes “do not repeat yourself”) is a principle of software development aimed at reducing repetition of software patterns, replacing it with abstractions or using data normalization to avoid redundancy.

What is DRY principle explain with an example?

To prevent redundancies in logic (code), followers of the DRY principle use abstraction to minimize repetition. When the DRY principle is followed, for example, a software developer should be able to change code in one place, and have the change automatically applied to every instance of the code in question.

Is rest a IPC?

REST is an IPC mechanism that (almost always) uses HTTP. A key concept in REST is a resource, which typically represents a business object such as a Customer or Product, or a collection of business objects.

What is Netflix OSS?

Netflix OSS is a set of frameworks and libraries that Netflix wrote to solve some interesting distributed-systems problems at scale. Patterns for service discovery, load balancing, fault-tolerance, etc are incredibly important concepts for scalable distributed systems and Netflix brings nice solutions for these.

What is difference between SOA and Microservices?

The main difference between SOA and microservices: Scope To put it simply, service-oriented architecture (SOA) has an enterprise scope, while the microservices architecture has an application scope. Many of the core principles of each approach become incompatible when you neglect this difference.

What is Strangler pattern?

Understanding the Strangler pattern The Strangler pattern is one in which an “old” system is put behind an intermediary facade. Then, over time external replacement services for the old system are added behind the facade. Eventually, the services in the old system get “strangled” in favor of the new services.

What are different types of microservices?

Broadly speaking, there are two types of microservices:

• Stateless microservices.
• Stateful microservices.
