A notification is a message that pops up on the user’s device. Notifications can be triggered locally by an open application, or they can be “pushed” from the server to the user even when the app is not running. They allow your users to opt-in to timely updates and allow you to effectively re-engage users with customised content.
Continue reading Push NotificationsIn an event-driven architecture, when a service performs some piece of work that other services might be interested in, that service produces an event—a record of the completed action. Other services consume those events so that they can perform any of their tasks needed as a result of the event. Unlike with REST, services that create requests do not need to know the details of the services consuming the requests. Here’s a simple example: When an order is placed on an e-commerce site, a single “order placed” event is produced and then consumed by several microservices:
Continue reading What is Event-Driven Microservice Architecture?(Avoid shared databases). When multiple services consume a shared data schema, it can create tight coupling at the data layer. To avoid tight coupling, each service should have its data access logic and separate data store. The development team is free to pick the data persistence method which best fit each service and nature of data.

It sounds like a reverse proxy, but also has additional responsibilities like simple load-balancing, authentication & authorization, failure handling, auditing, protocol translations, and routing. There are several ways in which the API Gateway can be deployed from a development perspective.

In this post, I’ll endeavour to take the mystery and explain things in plain English so you can build genuinely modular, business agile IT systems with Microservices architectural style.
The goal of microservices is to increase the velocity of application releases, by decomposing the application into small autonomous services that can be deployed independently.

Let’s get to work and see what it is all about, we’ll go over the following:

With the performance, the main improvement to the methods, check and see the typical speedups of up to 2x over Json.NET.
The new feature Async Streams in C# has removed the scalar result limitation and allows the async method to returns multiple results.
This change makes the async pattern more flexible so that you can retrieve data in lazy asynchronous sequence from a database or you can download data from an asynchronous sequence that returns the data in chunks when they become available.
Continue reading Async StreamsIt is possible to trick a user into executing potentially dangerous actions against the target site due to a lack of Cross- Site-Request-Forgery (CSRF) protections. CSRF attacks are a class of confused deputy attacks that exploit the behaviour of browsers always sending authorization cookies in requests. The target site has no secure way of verifying the request was initiated from a link on a trusted domain.
