Microservices design patterns

By -

Microservices are an architectural pattern where a large application is divided into smaller, independent services that communicate with each other through APIs. Here are some common patterns used in microservices architecture

  • API Gateway Pattern: A centralized entry point for all client requests that routes requests to the appropriate service.
  • Service Registry Pattern: A centralized service that acts as a directory of all available services, making it easy for services to discover each other and communicate.
  • Circuit Breaker Pattern: A mechanism that prevents a service from making requests to a failed service, improving overall system stability.
  • Load Balancer Pattern: A component that distributes incoming requests evenly across multiple instances of a service, improving reliability and scalability.
  • Event-Driven Pattern: A communication pattern where services communicate with each other by sending and receiving events, rather than direct request-response calls.
  • Bulkhead Pattern: A mechanism that isolates a service's resources, such as threads or connections, to prevent one service from impacting the performance of another.
  • Sidecar Pattern: A pattern where an auxiliary service is deployed alongside the main service to perform specific tasks, such as service discovery, configuration management, or monitoring.
  • Compensating Transaction Pattern: A pattern used to undo the effects of a failed operation in a distributed system, maintaining consistency and integrity.

These patterns can help address some of the common challenges faced in microservices architecture, such as service discovery, resilience, scalability, and security. It's important to evaluate your specific requirements and choose the most appropriate patterns for your use case.

  Query the list of   CITY   names ending with vowels (a, e, i, o, u) from   STATION . Your result   cannot   contain duplicates. Input Format The  STATION  table is described as follows: where  LAT_N  is the northern latitude and  LONG_W  is the western longitude. Notes :  SUBSTR() The SUBSTR() function extracts a substring from a string (starting at any position). Note:  The SUBSTR() and  MID()  functions equals to the  SUBSTRING()  function. Syntax SUBSTR( string ,  start ,  length ) Parameter Values Parameter Description string Required. The string to extract from start Required. The start position. Can be both a positive or negative number. If it is a positive number, this function extracts from the beginning of the string. If it is a negative number, this function extracts from the end of the string length Optional. The number of characters to extract. If omitted, the whole string w...

public static void main(String [] args) - Full Explanation

Why JVM Call main() method? JVM is a program in which the main() method is configured that is the reason JVM called the main method. we can change the name of the main() method but we need to change the method calling in JVM. Explanation of the main method : public static void main(String [] args) is a method that is called by JVM.  Public : Public is an access modifier of the main method. the main method is public because the JVM can call this method from anywhere. static : without creating an object JVM can call this method that's why the main method is static. without an existing object also JVM has to call this method and the main method is not related to any Object. void:  void is a return type of the main method, the main method not returning any value to JVM. main : this is the method name that is configured in JVM.  String[] args : these are command-line arguments. The above syntax is very strict if we performed any change we will get a Runtime exception i.e No su...

Primitive Data Types in java

Primitive Data Types   Expect boolean and char remaining data types are consider assigned data types because we can represent both positive and negative numbers. byte : size : 1 byte  ( 8 bit) max value : 127 min value: 128 Range: -128 to 127 a byte is the best choice,  if we want to handle data in terms of streams either from file or form the network. syntax : byte b = 10; Default value : 0 short: size: 2 bytes (16 bit) Range: - 2 power 15 to 2 power 15 -1 the short data type is best suitable for 16-bit processors like 8085 but these processors are completed outdated and hence corresponding data type is also outdated datatype. syntax : short b = 10; Default value : 0 int : size: 4 bytes (32 bit) Range: -2 power 31 to 2 power 31 -1 syntax :  int b = 10; Default value : 0 long : size: 8 bytes (64 bit) Range : - 2 power 63 to 2 power 63 -1  syntax : long b = 1051541; Default value : 0 All the above data types (byte, short, int, long ) use to represent integral val...
