Traditionally, web applications were built as a monolithic app, designed to scale within a given server. In order to authenticate valid users, the classic approach was to use a “cookie” or a small object containing user information and store it in a “session” object on the server side. (more about session). In this approach, “state”…
Forms, as we all know, are a vital part of web development. All of us who are familiar with AngularJS will agree with the fact that how easy it is to develop robust scalable from-ends using AngularJS. But it comes with its own problems, one of the biggest being how to deal with big forms.…
Microservices has been a buzzword in software engineering recently. Everyone wants to build their application around Microservices architecture. Before you jump onto the bandwagon, lets do a critical review of Microservices. We will look at the cases where it is appropriate along with advantages and disadvantages. Before we proceed let us look at how to…
Each day, large amounts of data and metrics are collected from real time activity streams, performance metrics, application logs, web activity tracking and much more. Modern scalable applications need a messaging bus that can collect this massive continuous stream of data without sacrificing good performance and scalability. Apache Kafka is built ground up to solve…
While there are numerous advantages of deploying on the cloud, there are no guarantees that the cloud platform services will respond successfully every time. In a cloud environment periodic transient failures should be expected. The approach should be to minimize the impact of such failures on the application execution by anticipating and proactively handling failures.The…
In previous posts, we covered the benefits of moving to the cloud for scale and the design principles of building scalable applications. In this post, we will look at a typical reference architecture for a cloud based scalable application and cloud features that help your application scale.Architecture The below listed figure illustrates a reference architecture…
