Monolithic Architecture

Image
 Monolithic Architecture In our application, we will have several modules and several components are also available. Components are 1. Presentation Components These are responsible for handling Http Requests. Web applications means front end pages, Distributed applications means Rest Clients. 2. Web Components Responsible to handle user requests.(Servlets basically handles the Requests). 3. Business Components  Responsible to handle the business logic as per the business deals. 4. Persistence Components DAO is responsible for performing DB operations like DML,DDL,TCL,.... 5. Integration Components(Webservices, RestFul Services) Two projects can talk to each other only when we have Integration logic(basically RestfulServices, WebServices,...). 6. Authorization Components Responsible for Authorizing the user. 7. Notification Components Responsible for sending email or mobile message notifications. If we develop all these components as a single project then it is called as " Mono...

Advantages and Disadvantages of Monolithic Architecture

 Benefits of going for Monolith Architecture  Simple for development(becoz all are available in single project): At initial time it is very easy.   Easy for Testing : End to End Testing we can perform.   Easy for deployment : One war file only we have to deploy to server.   Easy for Scaling : multiple server we can spin easily(horizontal/vertical scaling) if requests increases then we can make keep multiple servers through which the scaling can be done to provide good responses to the client.  Disadvantages of Monolith Architecture  Maintenance of the application: If the application is to large and complex, it is difficult to understand. Change Request in the code is very difficult. Some changes in the existing application will have an impact to the other code, Lot of Impact Analysis will occur.   Adapting to New Technology is required: Change in java version and adapting to the version change also will take time. Applicati...

Load Balancers and Load Balancers Algorithms

Image
 Load Balancers When all components are in same applications, all request comes to same servers then burden will increase on the same server.  More the requests to the server, then the performance at the server side will be slow so the response time is high for clients.                                                                                                                                  Eg: Youtube, Myntra, Flipkart,.......(lakhs of users will send the request still the response time will be uniform for client)  When burden increased on server it will process the request slowly and some times the server might crash also.  To reduce the bu...
