What is Application Server Software for Cloud?

Application server software provides a platform for deploying, managing, and running applications, typically for web or enterprise environments. These servers handle the backend logic of applications, facilitating the connection between client devices and databases or other services. Application servers often provide middleware services such as security, transaction management, and messaging, enabling the smooth execution of applications. They are designed to support multiple users simultaneously and ensure high availability, scalability, and performance of applications. This software is commonly used in environments where complex, data-intensive applications are developed, such as in e-commerce platforms, enterprise resource planning (ERP), and customer relationship management (CRM) systems.

Thanks to the excellent DietPi distro this tiny server runs Epesi surprisingly well especially on a fast SD card. It should run unmodified on any Raspberry Pi - from the lowest end $5 RPi Zero with no WiFi and 1 CPU and 512 MB of RAM (used to create this disk image), to the high end RPi 4. Tested fine on RPi 3 - unmodified, just swapped between units! MIT License • Copyright (c) 2024 by Janusz Tylek and Karina Tylek

TidalScale

TidalScale

TidalScale software-defined servers represent a breakthrough in computing. TidalScale’s software solution “glues” your commodity servers together so that they function as a single system. The software accomplishes this by aggregating and virtualizing the CPU cores, memory, and I/O of multiple physical servers, and then presenting them as a single “software-defined server” to the operating system. Now with TidalGuard™ technology, individual servers can be hot-swapped allowing them to be upgraded or repaired all while the mission-critical workload continues to run. And all of this requires no changes to either the application or the operating system! With built-in patented TidalGuard™ technology, software-defined servers help detect and avoid over 90% of hardware failures via hot-swapping of a failing server with a spare. In the rare case that a server does fail, a software-defined server can immediately restart using the spare in a matter of minutes.
