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; It has several problems. Moreover, when using this architecture, many issues must address.

The microservice architecture pattern language is a set of patterns for applying the microservice architecture. It has two goals:

  • The pattern language allows whether microservices are a good place for application.
  • The pattern language allows the microservice architecture favorably.

Characteristics of Microservices

  • Autonomous - Each element set in a microservices architecture can be developed, deployed, operated, and scaled without affecting the functioning of other benefits. Services don't need to share any code or implementation with other services. Any connection between individual components happens through APIs. 
  • Specialized - Each service is designed for a collection of capabilities and focuses on solving a specific problem. 
Benefits of Microservices
  • Agility - promote an organization of small and independent teams that take ownership of their services. Groups work in a small and well-understood context and are allowed to work independently and fast. It helps to shorten construction cycle times. It benefits significantly from the throughput of the organization.
  • Flexible Scaling - Each service is to be independently scaled to meet the demand for its support application. It enables teams to support requirements, precisely measure the cost of a feature, and manage availability if a service experiences a spike in demand.
  • Easy Deployment - Enable continuous combination and delivery, helps try out new ideas, and rolls back if something doesn't work. The low cost of failure enables experimentation to update code and stimulates time-to-market for new features.
  • Technological Freedom - It doesn't follow a "one size fits all" plan. Teams have chosen the best tool to solve specific problems.
  • Reusable Code - Dividing software into small modules, which enables teams to use functions for multiple purposes.
  • Resilience - Service independence increases an application's stand to failure. With microservices, applications handle complete service failure by discrediting functionality and not crashing the entire application.

    This information supports me in learning and understanding the topic for the CS course. The material can students expect to apply what was learned in their future practice by small subject containing many types of information.

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

weekly blog (week one)

Hello, Everyone. How are you guys doing? This past week, I read some articles or news related to CS (Computer Science). I finally picked a topic that caught my attention; engineers create 3D-printed objects that sense how users interact. My reason for why and seeing how choosing this article is because it looks cool and relatable for Gamers to use any controller made of small rubber pieces.    Short Summary : The researchers found a way to combine sensing capabilities into 3D printable structures made of constant cells, enabling designers to prototype interactive input devices quickly. Even, Formed a new method to 3D print mechanisms that detect how force applies to an object. Or The structures are made from a single piece of material so that they can be rapidly prototypes. Also, A designer could use this method to 3D print "interactive input devices," as a joystick or a controller. For accomplishing the goal, the researchers blended electrodes into structures made from metam

Hello, week-9. I want to post a blog to quickly review the API topic to learn more about  REST  calls. I got confused; I researched about it. It has the Understanding And Using REST APIs.   What is a REST API   API (Application Programming Interface) - A set of rules allows programs to support any other. The developer creates the API on the server and enables the client to speak to it.  The REST (Representational State Transfer) determines how the API. It is a set of rules that developers follow when they create their API. One of the rules states that one should get data (called a resource) when linking to a specific URL. Each URL made a request, while the data sent back to is called a response. The Anatomy Of A Request # It’s important to know that a request with four points: The endpoint The method The headers The data (or body)   The endpoint  - URL that requests for (root-endpoint/?). The root-endpoint is the starting point of the API that is ordering. The path determines the resou
