Microservices: Concepts

 The microservice architecture is one of the most recent approaches to developing enterprise software applications. The concept of this style of software architecture has been discussed since 2011, and it has been establishing itself quickly. 

concept of microservice is like :

The microservice architectural style is an approach to developing a single application as a suite of small services, each running in its own process and communicating with lightweight mechanisms. These services are built around business capabilities and independently deployable by fully automated deployment machinery. There is a bare minimum of centralized management of these services, which may be written in different programming languages and use different data storage technologies.


Why microservices?

"Microservices is a phenomenon of building applications as a collection of multiple independent services which are loosely coupled".
It is nothing but decomposing the application into various modules which are independent of each other.

The primary advantage of Microservices is that the modules can be independently deployed. The team size of developers is very less (5-10),so that deployment is very fast.
There is no need of working with single technology for the entire application as like of monolithic kernel. Various technologies can be used to build the application and it makes developers to comfortably work as their interest.



In the same e-commerce example, with the use of microservices, the services can be divided into various groups and it makes the developer teams easy to maintain and deploy.
These microservices can communicate each other synchronously with REST API over http and asynchronously using message brokers like KAFKA,ACTIVEMQ etc.

Popular Microservices frameworks:

  • Spring Boot (Best microservices framework in Java)
  • Flask(Popular microservices framework in Python)
  • Drop wizard(Java)
  • Spark framework(Java)
  • Swagger(Java)
  • Jersey(Java)

What is Amazon Web Services (AWS)?

 Amazon Web Services Amazon Web Services is a cloud computing platform provided by Amazon. The AWS offers all three service models such as Software as a Service (SaaS), Infrastructure as a Service (IAAS), and Platform as a Service (PaaS). There are more services which comprise the Amazon Web Services including Amazon Elastic Compute Cloud (EC2) which provides virtual servers, Amazon Simple Storage Service (S3) which provides scalable storage for backups, analytics. Then there are other services such as Amazon relational database management system, DynamoDB, AWS Migration hub, and more. AWS provides services in almost every category from mobile development to data analytics. Benefits of using Amazon Web Services: AWS gives access to organizations to use programming models , database and operating system. It provides a cost effective service in which you only have to pay for what you use. Applications can be deployed in multiple regions with just a few clicks. ...

Fail Fast and Fail Safe Iterator in Java

  The concepts of "fail-safe" and "fail-fast" are often discussed in the context of data structures and algorithms, particularly in Java programming. Let's understand what each concept means: Fail-Safe: Fail-safe refers to the property of a system or data structure that guarantees it will not fail, crash, or produce incorrect results, even when it encounters unexpected inputs or concurrent modifications. In the context of Java collections, a fail-safe iterator is an iterator that does not throw a ConcurrentModificationException if the collection is modified while it's being iterated. Instead, it operates on a copy of the original collection or uses some mechanism to handle concurrent modifications safely. For example, the Iterator returned by HashMap or ConcurrentHashMap in Java is fail-safe. If a collection is modified while an iterator is traversing it, the iterator will continue to operate on the original elements that were present when the iteration ...
