Microservices in 60 mins | Learning Path & Interview Preparation

In this video, We will learn about different design patterns and tools used in Microservices. We also covered a popular microservices interview question : Tell me about the tools and design patterns that you have used in microservices. When it comes to Microservices , A developer is involved right from creating Microservices to deploying it cloud, hence understanding the each phase of the Microservices development is important. Defining Microservices Boundaries —————— When we create a Microservice, the first thing that we do is define the boundary of our Microservice (Bounded Context). For an example a sms-service should have sending sms related scope inside the project. It should not deal with the Payment processing stuffs inside the same project. That’s why defining the boundary for a Microservices plays a very important role, when it comes to maintainability of code. Microservices Communication ———————— All our Microservices should communicate with each other. In order to make this communicate happen, we can use RESTful web services, Messaging service, Event streaming etc. Apache Artemis, Active MQ, Rabbit MQ, Kafka are some popular message brokers Microservices Deployment ————— Virtual machine might not be an Ideal solution for the Microservices deployment. Even Though VM’s are widely used in industry, But creating a VM is a tedious job as it involves a manual process of 1. Distribution or memory 2. OS installation 3. Library installation etc As a Virtual Machine Involves an Operating System, It’s not fast to bootstrap and shutdown. So it doesn’t help much in a Microservices environment , where we need quick deployment of our Microservices when the load increases. We also need a autoscaling feature where we can automate our Microservices deployment. Here the Docker and kubernetes comes handy. We can replace our VM’s with container which doesn’t involve an OS and pretty fast in comparison to VM. Microservices Design Patterns ——————————— Microservices Architecture helps us to split our huge monolith application to pieces and makes the developer life easy. But with this simplicity, there comes a lot of responsibility and challenges. To help us solve the challenges, We have proven design pattern. 1. With a handful of Microservices, We need to manage a lot of server where these Microservices are deployed. To manage these server ip’s we use a design pattern called service discovery and registration design pattern. 2. Our Microsrvices should be fault tolerant. To make our Microservices resilient, We use design patterns like Circuit breaker design pattern, Retry Pattern, Bulk Head pattern, Rate Limiter pattern etc. 3. To address cross cutting concerns like Security, Logging,Tracing; We use a design pattern called Gateway design pattern. 4. To Manage distributed Transaction, We use Saga design pattern. 5. There are other design patterns concepts like Load balance, DDD, CQRS, Event Driven etc which can helps boosting the performance of our Microservices application. We have discussed all of these in this microservices roadmap video and you can use the timestamp to navigate to different microservices tool and design patterns KT.
