The preferred way to handle concurrency and synchronization in Go is through goroutines and channels. However, Go does provide more traditional multithreading routines in the sync and sync/atomic packages. Mutexes A mutex (mutual exclusive lock) locks a section of code to a single thread at a time and is used…

Deciding on how microservices communicate with each other is one of the most important and fundamental decisions to make when implementing a system based on a microservices architecture. Helping to find out the most suitable choice of Interprocess communication(IPC) is the key challenge that this thesis work is aiming to…

Technology Diverseness: Systems that are built based on Microservices architecture is a collection of independent services that communicate with each other over a network. This feature enables choosing the most suitable programming language, framework, or data modeling according to the requirements of that particular service instead of having a universal…

Microservices are one of the architectural approaches for building distributed software applications. Organizations are adopting Microservice architecture to achieve faster delivery, better resiliency, and higher safety as the scale of their systems increases. Over the past decade, microservices have been used in different forms while they shared some common characteristics. …

Most of today’s enterprise IT applications are distributed — either at a larger- scale that operates over the internet or as a collection of local networks. The demand for developing Distributed Systems has increased significantly over the past years as applications are now required to serve a wide range of…

Introduction interfaceI would like people who are studying the Go language to read it because it is difficult to understand when it gets involved. In particular, Tour of Go of Stringers assumes that you no longer know as per se. Also, since the purpose is to deepen the understanding compared to…

The Platform Business Headquarters provides common API and GUI parts that support each DMM business. The Infrastructure Development Group is developing the infrastructure. Nowadays, we are especially working on improving API quality and automating operations. Now, more than a year has passed since the second generation API-Gateway (Gen2-GW) of DMM…

I had the opportunity to launch a new microservice and based on a clean architecture. Clean architecture is used in many places such as backends, frontends, and apps. However, there is no definite method, and I think everyone is doing trial and error. …

After searching around for a few hours, I cannot seem to find what I’m looking for and the documentation on this subject is non-existent. I needed access to the package in a lambda function however I have been unsuccessful finding the Pandas and NumPy packages for usage in a Lambda…
