I often work on applications whose sole task is to execute a script at certain time or day. You may approach it in several ways, eg.: Task Scheduler (Windows), SQL Job (if it is a SQL task) or CRON in Linux. You may also write application, which would run in background and execute a script at certain time. The only question is – do you really want do it? In this post, I would like to introduce other solution to tasks like this. ...
Not so long ago, I’ve eventually decided to dive into the world of microservices. I did look for an opportunity to make use of this architectural pattern for quite some time and finally was able to do so. After 3 months of trying out the new things and learning stuff mostly on my own (the hard way) I believe it’s a good time to share some of my experience. I have no doubts that at some point in the future when I look back at this post I might be like – “oh God, what was I thinking back then, it’s so wro...
It’s been quite a while since I’ve started gathering some knowledge about the microservices architectural pattern that’s been on a hype recently. After reading many articles, some books like Microservices in .NET Core and talking with smart guys in the Devs PL Slack channel, I’ve eventually decided that the time has to come to try to make the microservices happen in the real world project. That’s the beginning of my journey into the distributed programming and architecture, so please keep that in mind wh...
I suppose there are not so many people who do not know what Node.js is. You may love it, you may hate it, but you cannot deny the fact that more and more enterprises are using it to replace some parts of their system, previously written in Java, Rails or .Net. Node.js runs in a lot of environments – starting from large, multi-core servers, through laptops, then microcomputers like Rasperry Pi, finishing on IoT devices...
MiSeCo #8: Service discovery methods ?>michalComments 0 Comment This is an 8th post in a series about MiSeCo – a project I am working on for the “Daj się poznać” challenge (in Polish). So far I have implemented a way of calling service methods remotely over HTTP protocol. Currently, service URL is hard-coded in the application. I need to find a way to allow services register automatically so that very little configuration is needed. Initially, I wanted to create MiSeCo in the way that there is no c...
This post describes how to minimize overhead when developing systems with microservices architecture, especially as it comes to development and deployment. Some time ago, we published similar post about solving this problem in Microsoft and Azure world. This time we will focus on AWS, Java, Spring Boot, Docker and some useful open source libraries from Netflix.
This is the first one of two posts concerning approach to build cost effective, but prepared for scaling systems, using ASP.NET Web API and Azure. In the era of building systems that aim to provide services at global scale, requirements for scalability and high availability are becoming our bread and butter. What is more, it is absolutely normal that stakeholders want first shippable version of software as soon as possible.
Tyle się mówi o rozwoju programistów. Ba, sam o tym często gadam. Że to dobre, że trzeba, żeby nie stać w miejscu a iść do przodu… Ale powiedzcie mi: jak ma się rozwijać programista w typowym programistycznym polskim (i pewnie nie tylko) dev-kołhozie? Przychodzi do roboty, siada do projektu, po 8h wstaje i wychodzi. Niby normalka, ale… niekoniecznie. Moim zdaniem kluczowe jest pytanie: do jakiego projektu ten pr...
