Reading Time: 4 minutes When we create any microservice, or in general any service, one of the biggest task is to manage data persistence. Lagom supports various databases for doing this task. By default, Lagom uses Cassandra to persist data.
Reading Time: 4 minutes One of the challenges faced by distributed systems is how to keep the replicas consistent with each other. Maintaining consistency requires balancing availability and partitioning. Fortunately, Apache Cassandra lets us tune this balancing according to our needs. In this blog, we are going to see how we can tune consistency levels during reads and writes to achieve faster reads and writes. Before digging more about Continue Reading
Reading Time: 4 minutes A reactive system primarily focuses on responsiveness, elasticity, message-driven, and resiliency as its core features. Elasticity is one of the main components in the reactive manifesto. An elastic system has the ability to scale up or scale down when there is an increase/decrease in demand while remaining responsive. Scenarios where a system needs to improve the throughput or needs to handle more concurrent users, we Continue Reading
Reading Time: 4 minutes The first law of distribution is “Don’t Distribute“. If everything can be done on a single machine then nothing beats that. But, lets cut to reality. Today’s computing and information systems are inherently distributed. Starting from large data centers to cloud storage to your mobile phone, everything is a part of the distributed infrastructure. Distribution, just like distributed development teams is here to stay because Continue Reading
Reading Time: 7 minutes Ever wondered why do companies like Apple, eBay and Netflix care so much about microservices? What makes this simple architecture so special that it is being hyped so much? Is it worth the pain and efforts to shift an entire running application from monolithic to microservices architecture? Many such questions came to our minds when we started using the microservices in our projects. In this Continue Reading
Reading Time: 3 minutes In this blog,we are going to embark the journey of how to setup the Hadoop Multi-Node cluster on a distributed environment. So lets do not waste any time, and let’s get started. Here are steps you need to perform. Prerequisite: 1.Download & install Hadoop for local machine (Single Node Setup) http://hadoop.apache.org/releases.html – 2.7.3 use java : jdk1.8.0_111 2. Download Apache Spark from : http://spark.apache.org/downloads.html choose spark release Continue Reading
