This not only speeds up the delivery but also frees up your main server from resources so that it can attend to more critical requests!</p> devops cdn webdev beginners Harith Javed Bakhrani Tue, 10 Sep 2019 06:40:44 +0000 https://dev.to/thecodebulb/communication-between-the-application-and-the-server-in-the-same-network-closed-1hc7 https://dev.to/thecodebulb/communication-between-the-application-and-the-server-in-the-same-network-closed-1hc7 <div class="ltag__stackexchange--container"> <div class="ltag__stackexchange--title-container"> <div class="ltag__stackexchange--title"> <div class="ltag__stackexchange--header"> <img src="https://media2.dev.to/dynamic/image/width=800%2Cheight=%2Cfit=scale-down%2Cgravity=auto%2Cformat=auto/https%3A%2F%2Fassets.dev.to%2Fassets%2Fstackoverflow-logo-b42691ae545e4810b105ee957979a853a696085e67e43ee14c5699cf3e890fb4.svg" alt=""> <a href="https://stackoverflow.com/questions/57757892/communication-between-the-application-and-the-server-in-the-same-network" rel="noopener noreferrer"> Communication between the application and the server in the same network </a> </div> <div class="ltag__stackexchange--post-metadata"> <span>Sep 2 '19</span> <span>Comments: 1</span> <span>Answers: 1</span> </div> </div> <a class="ltag__stackexchange--score-container" href="https://stackoverflow.com/questions/57757892/communication-between-the-application-and-the-server-in-the-same-network" rel="noopener noreferrer"> <img src="https://media2.dev.to/dynamic/image/width=800%2Cheight=%2Cfit=scale-down%2Cgravity=auto%2Cformat=auto/https%3A%2F%2Fassets.dev.to%2Fassets%2Fstackexchange-arrow-up-eff2e2849e67d156181d258e38802c0b57fa011f74164a7f97675ca3b6ab756b.svg" alt=""> <div class="ltag__stackexchange--score-number"> -3 </div> <img src="https://media2.dev.to/dynamic/image/width=800%2Cheight=%2Cfit=scale-down%2Cgravity=auto%2Cformat=auto/https%3A%2F%2Fassets.dev.to%2Fassets%2Fstackexchange-arrow-down-4349fac0dd932d284fab7e4dd9846f19a3710558efde0d2dfd05897f3eeb9aba.svg" alt=""> </a> </div> <div class="ltag__stackexchange--body"> <p>I am in the process of developing a CI/CD tool that would be running on kubernetes.
