Hello Xie, here are the tools am using for my entire CI/CD pipeline : 1-Jenkins (make sure to install Blue Ocean plugin) it will make your life easier and it's user friendly. 2-Gitlab as a container registry for my docker images (you can use it for code source too of course) 3-Github for version control and source code (make sure to benefit from webhooks to interact with your jenkins server). 4-Ansible : in order to automatically execute shell commands on different machines local and remote. 5-As always i recommend Kubernetes to manage containers (that's what am using) Best of luck

Hello Luis, you have 4 choices :

1-Minikube (works on a single node) 2-Microk8s (works on a single node) 3-Bare metal Kubernetes cluster (multi nodes) 4-Managed Kubernetes cluster (multi nodes)

I've used all the 4 and for a beginner i highly recommend Microk8s because it's the most simple and straight forward tool to use a lightweight kubernetes distribution on a single machine (can be a simple laptop). You will need to enable some important addons (they come disabled by default). You need to activate CoreDns (responsible of networking) and Ingress (responsible of port forwarding). When you become proficient you can use a bare metal cluster (multi nodes and even multi masters). And for production you can use choice 4 wish is a very bad choice if you want to learn some skills because all the heavy lifting is done by the cloud provider. Bonus : You also can use Scaffold (Google tool) that enable you to deploy docker images on a local k8s cluster.

Hello, i build microservice systems using Angular And Spring (Java) so i can't help with with ur back end choice, BUT, i definitely advice you to use a Nosql database, thus MongoDB of course or even Cassandra if your looking for extreme scalability with zero point of failure. Anyway, Nosql if much more faster then Sql (in your case Postresql DB). All you wanna do with sql can also be done by nosql (not the opposite of course).I also advice you to use docker containers + kubernetes to orchestrate them, if you need scalability and replication, that way your app can support auto scalability (in case ur users number goes high). Best of luck

Hello, i highly recommend Apache Kafka, to me it's the best. You can deploy it in cluster mode inside K8S, thus you can have a Highly available system (also auto scalable).

Good luck

I recommend this : -Spring reactive for back end : the fact it's reactive (async) it consumes half of the resources that a sync platform needs (so less CPU -> less money). -Angular : Web Front end ; it's gives you the possibility to use PWA which is a cheap replacement for a mobile app (but more less popular). -Docker images. -Kubernetes to orchestrate all the containers. -I Use Jenkins / blueocean, ansible for my CI/CD (with Github of course) -AWS of course : u can run a K8S cluster there, make it multi AZ (availability zones) to be highly available, use a load balancer and an auto scaler and ur good to go. -You can store data by taking any managed DB or u can deploy ur own (cheap but risky).

You pay less money, but u need some technical 2 - 3 guys to make that done.

Good luck
