Go Chassis
A cloud native application framework for Go with rich eco-system
Go-Chassis is a microservice framework for the rapid development of microservices in Go. it focuses on helping developer to deliver cloud-native applications more easily. The idea of the logo is, developers can recreate and customize their own "wheel"(a framework) by going chassis to accelerate the delivery of software. Powerful middleware "handler chain": powerful than "filter" or "interceptor". each handler in the chain is able to get the running result of the backward handler and your business logic. It is very useful in a variety of scenarios. Go Chassis is designed as a protocol-independent framework, any protocol is able to integrate with go chassis and leverage the same functions like load balancing, circuit breaker, rate limiting, and routing management, those functions are resilient to your service. Support Service center, kubernetes. fit both client side discovery and server side discovery pattern, and you can disable service discovery to use end to end communication. -

nanomsg
nanomsg library
The nanomsg library is a simple high-performance implementation of several "scalability protocols". These scalability protocols are lightweight messaging protocols that can be used to solve a number of very common messaging patterns, such as request/reply, publish/subscribe, surveyor/respondent, and so forth. These protocols can run over a variety of transports such as TCP, UNIX sockets, and even WebSocket. This pattern is useful for solving producer/consumer problems, including load-balancing. Messages flow from the push side to the pull side. If multiple peers are connected, the pattern attempts to distribute fairly. nanomsg is a socket library that provides several common communication patterns. It aims to make the networking layer fast, scalable, and easy to use. Implemented in C, it works on a wide range of operating systems with no further dependencies. The communication patterns, also called "scalability protocols", are basic blocks for building distributed systems. -

Zappa - Serverless Python
Serverless Python
Zappa makes it super easy to build and deploy server-less, event-driven Python applications (including, but not limited to, WSGI web apps) on AWS Lambda + API Gateway. Think of it as "serverless" web hosting for your Python apps. That means infinite scaling, zero downtime, zero maintenance - and at a fraction of the cost of your current deployments! With a traditional HTTP server, the server is online 24/7, processing requests one by one as they come in. If the queue of incoming requests grows too large, some requests will time out. With Zappa, each request is given its own virtual HTTP "server" by Amazon API Gateway. AWS handles the horizontal scaling automatically, so no requests ever time out. Each request then calls your application from a memory cache in AWS Lambda and returns the response via Python's WSGI interface. After your app returns, the "server" dies. -

RocketMiX
RocketMix API Platform
Go to project's home page here (in french only) : https://rocketmix.github.io Go to source code and technical documentation here : https://github.com/rocketmix/rocketmix.source RocketMiX is an open source API platform build on "classic" Spring and Netflix components. It contains : * a routing server * a management server (which embeds a directory of your APIs and a monitoring UI) * a Spring Boot Starter module (hosted on Maven central) RocketMiX aims to be a simplified API Plateform. To perform that, we simplified everything and just offered Linux executables instead of complex Java packages: one for the routing server and one for the management server. APIs you would build using our Spring Boot Starter module would automatically register themselves t make calls automatically routed to them. RocketMiX also offers some documentation features (with Swagger UI and OpenAPI specs), security, load-balancing and many more. -

MySQL Load Balancing PHP script
MySQL Load Balancing PHP script
Free MySQL Load Balancing PHP script. For load balanced access to your MySQL servers when you are using MySQL replication between one (or many) master and many slaves. This script does reads on slaves and writes on master(s). It automatically checks if the challenger slave is "fresh enough" to read on it. The script is actually used in real conditions, prove of the capabilities. That also needed from me to erase some sections of the code replaced by a "TODO" commentary with instruction (you will have to adapt those few lines to your conditions). Comes with a mail alert script for errors logging and reporting, really useful for debug issues. Renaud CAMPO -

Bat2015
Bachelor of Science (Informatik)
The toolkit glpk supports methods for mixed integer linear programming (MILP). These methods solve Capital Budgeting Problems (CBP). Unfortunately, glpk does not support any multithreading and there is no feature to distribute problems via network connections. Today, this is a pitiable sight, because modern computer systems are coupled by networks and support multi threading. We create a distributed system with Apache thrift and the C-API of glpk. Now, it is possible to use as many cores in a network as you want. With a focus on the MILP methods we implement a load balancing and speed up the solving process in a multiplicative way. Sometimes we have super-linear speedup with a small set of hardware. With a splitting of problems, parallel computing and distributing the actual best solution to all running processes we solve CBP much faster than a sequential processing can do. -
