Software Architecture & Technology of Large-Scale Systems by Udemy
Learn Architecting Software Systems with High Performance, Scalability, Availability, Security using Modern Technologies
Course Highlights
- Architecting Software Systems and Solutions: We will start with a basic three tier application architecture which we will enhance as we move along.
- How to build a technical stack by getting architectural insights into products like Nodejs, Redis, Cassandra, Kafka, Hadoop, Elastic Search, .. and many more
- Non-Functional Requirements: How to design architecture considering Performance, Scalability, Reliability, and Security
- Deployment of large scale production systems using tools like Docker & Kubernetes
