Andrew Lam’s little blog

Hello, I want to write this blog after looking over some class activities again and seeing any questions to review, but something caught my attention. I read the word "microservices" in some class-work exercises; I got interested and looked it up again. I found two links that helped me understand What are microservices? And examples from Amazon company.   What are microservices?   Microservices (microservice architecture) - is an architectural method that structures an application as a collection of services that are Highly maintainable and testable Loosely linked  Individually deployable Organized around business capabilities Owned by a small team The microservice architecture makes applications easier to scale and faster to develop, enabling innovation and accelerating time-to-market for new features to reduce complex applications. It even allows an organization to evolve its technology stack. The pattern language guide   The microservice architecture isn't perfect;

Hello, I want to write this blog after finishing my exam like an hour ago; I am looking over some class activities and see any questions to review, but something that sometimes confused me. I read the word "docker-compose" in some class-work exercises; I got interested and looked it up again. I found two links that helped me understand what Docker Compose does and how you use Docker Compose?. Docker Compose:  Run multiple containers as a single service or extend many different Docker containers midway. Even an essential tool for any application that needs various micro-services, as it allows each service to be in a separately managed container easily. What Does Docker Compose Do? Docker containers are running applications in an isolated environment. Its application deployments are arranged in Docker for the benefit. However, it's often complex as running a single container. Usually, Many containers come together to act as one service made up of many changing parts. Runnin

Hello, I am doing some class activities and looking over some questions ahead to save time for a thing or two. I came across the word "Behavioral Patterns" in class Act. 4 (Model 8); I got curious and looked it up. I found two articles that helped me understand the purposes, Problems with solutions, Real-World Analogy, Structure, Pseudo-code, Applicability, How to Implement, Pros and Cons, Relations with Other Patterns. The Behavioral Patterns are concerned with providing solutions. It is about object interaction - how they communicate, how some are dependent on others, how to separate them to be both dependent and independent, and give both flexibility and testing capabilities—also, the assignment of responsibilities between objects. The Behavioral Patterns cover many small parts to form the full extend of patterns. Like Interpreter, Template Method/Pattern, Chain of Responsibility, Command, Iterator, Mediator, Memento, Observer, State, Strategy, and Visitor. Interpreter The
