 Web server

Normally web server එකකට පුළුවන් user static page එකක් ඉල්ලුවොත් එක response එක විදිහට යවන්න විතරයි.එකේ වැඩි දෙයක් නෑ.ඒ page එක හදලා තියෙන්නේ, මට එක දෙන්න කියල ඉල්ලුවාම එක දෙනවා, එච්චරයි...එත් back-end part එකක් තියන වෙලාවක, ඒ කියන්නේ dynamic page එකක් හදන්න ඕනේ වෙලාවට එක කරන්න බෑ.එකට web-sever එකට plug-in එකක් අවශ්‍ය වෙනවා.ඒ plugging එක හරහා තමා  dynamic pages generate කරලා ඒක  user ට response එක විදිහට යවන්නේ(plugging : tomcat,.NET).

Web server examples: Apache, IIS (Internet Information Service: - Microsoft තමා develop කරලා තියෙන්නේ)

Web server එකට ගහන plugging වලට web container කියනවා.මේවා තමා servlet, JSP, JSF වගේ ඒවත් එක්ක වැඩ කරන්නේ.

Example:

ISS කියන්නේ Microsoft වලින් හදපු web server එකක් වන අතර Microsoft වලින් හදපු back-end language වන  C# run කරන්න (VB.net,ASP.net)  .NET කියන plugging එක ISS වලට set කරනවා.

Apache වලට tomcat plugging එක set කරනවා (web container එක).

What is MicroService? MicroService යනු තනි application එකක් (Monolithic Application එකක්), එකිනෙක communicate කරගන පුළුවන් වෙන වෙනම deploy වන කුඩා කුඩා independent services වලට කැඩීමයි. Simply it is new way to develop application rather than traditional monolithic application. Companies which are using microservice.   Features of MicroService Architecture Small focused – main aim of microservice is simplicity.it can be rewrite in maintained without extra effort. Loosely coupled – development as well as deployment is quick. Language Neutral – few services can be Java, few is c# few can be python.it can be use depend on the service. Bounded Context – each microservice does not need to understand the implementation of the other microservice.
