AWS Certification notes

Those are my personal notes on AWS Solution Architect certification preparation. Hope you find them usefull.

To pass AWS certification, you should have:

• Sound knowledge about most of the AWS services ( EC2, VPC, RDS, Cloudfront, S3, Route53 etc,)
• Hands on experience with AWS services.
• Good knowledge of disaster recovery, security and High availability architectures.

If you do not have prior hands-on experience and knowledge or you have little knowledge about AWS services, it is better to take an online course. If you already have experience in architecting solutions on AWS it is not necessary to take an online course.

Introduction to Kafka

Kafka acts as a kind of write-ahead log (WAL) that records messages to a persistent store (disk) and allows subscribers to read and apply these changes to their own stores in a system appropriate time-frame.

Terminology:

• Producers send messages to brokers
• Consumers read messages from brokers
• Messages are sent to a topic

Messaging Microservices

Messaging and asynchronous patterns are completely natural with microservices, but a lot of the start of the art material concentrates on HTTP, JSON and REST. This document is about "Message-driven Microservices" with Spring. It tracks the convergence of various ideas that are floating around in Spring Cloud, Spring Boot and Spring XD.

There is already a spring-xd-module-runner project where we started experimenting with allowing user to develop and run an XD module locally. We can extrapolate from there to a more flexible model that leads optionally to a deployable XD module, but can also be used to form more flexible structures than a simple "stream".

Basic Programming Model

Just create MessageChannels "input" and/or "output" and add @EnableMessageBus and run your app as a Spring Boot app (single application context). You need to connect to the physical broker for the bus, which is automatic if the relevant bus imple

This is study path related to microservices. It is not a study path on programming, if you want to improve in this sense please take a look at this.
