Lets learn "Software design patterns"

-

 


In this tutorial, we'll be learning about the introduction of software design patterns and different design patterns that are being followed while writing the code. This would be an introductory tutorial we'll go in detail about all design patterns in detail in other tutorials.

Introduction

So whenever we are writing any application code, there are many ways to achieve the same behavior but sometimes we write a code in a way that whenever a new requirement comes it becomes difficult to extend the existing code but to rewrite everything. That's when design patterns would are helpful. 
Design patterns are the coding patterns that are adapted over time by experienced object-oriented developers. So such patterns are already tested. Code written with such patterns is scalable, readable, and extendable.  So it's helpful for any developer to use the correct design pattern to write a code in a way that is scalable, readable, and maintainable.

Types of design patterns

There are three types of design patterns
  1. Creational: These types of design patterns are related to object creation and class instantiation. These can be further categorized as object creational patterns and class creational patterns. Examples of creational design patterns are the Factory method, Abstract Factory, Builder, Singleton, Object pool, and prototype. 
  2. Structural: These types of design patterns include organizing different classes and objects to form larger structures and provide new functionality. Examples of structural patterns are Adapter, Bridge, Composite, Decorator, Facade, Flyweight, Private class data, and proxy.
  3. Behavioral: Behavioral pattern is for communication patterns between objects. Examples of behavioral patterns are a Chain of Responsibility, Command, Interpreter, Iterator, Mediator, Observer, Strategy, Visitor, etc.

Some popular design patterns

We'll cover these in detail in separate tutorials.
  1. Factory method
  2. Observer pattern
  3. Singleton design pattern
  4. Decorator pattern
  5. Strategy pattern
  6. Adapter pattern
  7. Command pattern
  8. Iterator pattern
  9. Curiously recurring template pattern
  10. Flyweight design pattern
  11. Facade design pattern
  12. Proxy design pattern
  13. Composite design pattern
  14. Prototype design pattern
  15. Abstract design pattern
  16. Bridge design pattern
  17. Template method design pattern
  18. Builder design pattern
  19. Chain of possibility design pattern

Lets learn "About kube proxy in iptables mode"

In this tutorial, we'll learn about the Kube-proxy in iptables mode. Basically, we'll see how Kube-proxy create iptables that help in load balancing and service discovery. If you are not familiar with Linux IPTables I would recommend to check out my tutorial on IPTables here  first and then come back to read this tutorial. Kube-proxy Kube-proxy when running in iptables mode basically watch kube-apiserver for new endpoints and create corresponding iptables rules and iptables are fully responsible for service discover and proper routing of traffic to corresponding pods. Kube-proxy needs to run on all k8s worker nodes. Below is a small video describing the working of kube-proxy in iptables mode.  src:  https://www.slideshare.net/CJCullen/kubernetes-networking-55835829 Now that we know what Kube-proxy is and how it Kube-proxy works, let deep dive into the types of iptables Kube-proxy adds to the firewall. Kube-proxy added IPTables To learn this let's consider an example. Consid

Lets learn "System design for paste bin (or any text sharing website)"

  In this tutorial, we'll learn about the system design for PasteBin. If you don't know what Pastebin is here goes its definition. Pastebin is a type of online content hosting service where users can store texts to share with others over the internet.  Pastebin system design requirements  Functional Basic - User should be able to paste the text, generate the link and share the link with other users. There should be the max size of the text that our system will support (say 10Mb) Users should be able to provide the custom URL path for the link created. Like if a user wants to create the links  www.pb.com/letlearn, he can give this URL and pastebin should create a link using this URL to share with others. The link or paste expiry feature should be there for each stored text. There can be default expiry time say 1 year but this should be configurable. Personalization means the user should be able to login to track all the pastes created by him and manage them. Non-Functional Durab

Lets learn "Factory design pattern"

-
 In this tutorial, we'll learn about the factory design pattern as in what it is, in which use cases this is being used and how it works. If you've are not familiar with what are software design patterns and what are its different types check out this tutorial. Introduction A factory design pattern is a creational design pattern that is related to object creation. In this pattern, we'll have a method to create an object without exposing its creation logic to the client. If a class method is creating an object it has to be static.  The idea is to create a static method ( factory method ) which instantiates a class without exposing its logic to the client and the client can use that method every time it needs to create an object of the class. The reason why the factory pattern is useful is that as it does not expose the logic of object creation, so if logic is changed, the client code need not to be changed. Usecases The place where this pattern is mostly used is library cod
