The key to designing microservices is to properly "defin[e] their boundaries and how they communicate," according to Marko Anastasov. "A loosely coupled service contains related behavior in one place and knows as little as possible about the rest of the system with which it collaborates." Anastasov's emphasis on "loose coupling" is critical. You want services to communicate asynchronously with a limited number of endpoints and no shared database. … [Read more...] about How to avoid turning microservices into distributed spaghetti code

While this may seem like a daunting task, these standardized interfaces would be designed to accomplish a single, discrete task, hence the 'micro' in microservice. In traditional systems design, you might pass data to another application that 'takes over' the remainder of the transaction. In a microservice environment, the application acts like a conductor, coordinating a function by asking hundreds of different services to perform a discrete task that's independent of the larger transaction. … [Read more...] about How to plan a microservices implementation
For the Alien 8 competition, Crash added a new rule - maps could be no larger than 75cm by 55cm. This was due to the entries becoming bigger and more elaborate (the winning Underwurlde map was more like a mural, measuring 5.5m by 2.5m). Therefore it required some skill to depict all of the game's 129 rooms while maintaining the required level of detail. Wil says: "It was two or three days of sitting on my bed with an A2 illustration board, a long ruler, a set square and my trusty Rotring technical pens that my parents had bought me. I'd spent weeks mapping out the game beforehand and had the game running most of the time to check I'd got things right but I never did rough out the whole of the final piece. It was quite the revelation to find out that the map was in the shape of a spaceship when you saw all the screens together. I just made up the stuff around the edges of the map as I went along." … [Read more...] about The seven treasures of Ultimate Play the Game
That concept is antithetical to microservice architecture. According to IBM, a "microservices component that is reused at runtime throughout an application results in dependencies that reduce agility and resilience." In the microservice world, it would even be preferable to duplicate code and accept data duplication to further decouple microservice components. The goal is complete independence of each part of an app, not interoperability between different ones. … [Read more...] about SOA versus microservices: How are they different?
In late April, after thousands of Catholic institutions had secured loans, several hundred Catholic leaders pressed for additional help on a call with President Trump. During the call, Trump underscored the coming presidential election and touted himself as the candidate best aligned with religious conservatives, boasting he was the "best (president) the Catholic church has ever seen," according to Crux, an online publication that covers church-related news. … [Read more...] about Catholic Church got $1.4B in federal funds
“They have to build into the system a little bit more flexibility for all employers, so if they’re on the program and they have these ups and downs (in revenue), they don’t lose access to the program,” said Hassan Yussuff, Canadian Labor Congress president. … [Read more...] about Post-lockdown: Canada aims to wean people from aid and get them working again
