I would like an web a software on AWS. Locally, I run it on Ubuntu VirtualBox VM with docker-compose, it requires 2-4 cores, 8G RAM, 30-40G disk. Do you think it will run on AWSS? Should I install docker-compose and app on a EC2? Elasticbean, ECS, (https://aws.amazon.com/about-aws/whats-new/2018/06/amazon-ecs-cli-supports-docker-compose-version-3/ ), or something else?
I am vary because my attempts to run it on an IT department managed KVM failed.
What resources are best to request for either of solutions?
At the moment it is more of prove of concept/demo, but eventually I hope deploying production on a Kubernetes cluster
I'm looking for, in the order of decreasing importance :
Simplicity and chances to succeed with deployment asap
costs
stability, QoS
You may want to consider using AWS Fargate. This lets you run container-based applications without having to managing the underlying EC2 instance. You can use Fargate with either ECS or EKS.
The ECS CLI that you link to in your question also helps you create your application and should make it easy get started.
You can look at ecsworkshop.com for an introduction to using ECS and Fargate.

I am currently learning kubernetes and would like to run a cronjob every 6 hours (job is running under a minute). Minikube is not suitable as I cannot ensure my laptop stay alive 24h/7d... I wonder what is the cost on main kubernetes providers (GCP, AWS, Azure) for this type of workload? Is it better to rent a VM and install a small kubernetes instance to do so?
Thanks
Getting former user feedback will be helpful.
You can have a look to Cloud Run and Cloud Run jobs that allow you to run container in serverless mode.
In addition, you can also have a look to GKE Autopilot where you pay only when you consume resource on the cluster (and the first cluster is free).
What is the difference between an AWS EC2 instance and a docker container instance? When should I use one over the other?
When you get an EC2 instance it will provide the base installation of that specific operating system with some additional AWS packages installed such as the SSM Agent.
There are then AMIs that are prepared for specific usecases such as SQL Server, or in this case pre-configured with AWS Orchestration services (either ECS or EKS) which have the usecase software installed.
If you're not familiar with Docker I would suggest running it in your local environment first so that you can become familiar with it. Yes people have been moving towards containers and serverless but you need to ensure you are able to support this in production.
With containers being deployed you will need to understand the orchestration layer that you're using. It's very easy to see containers as an alternative to a virtualisation layer, but there are many differences to how these operate.
Take a look at the What is Docker? page for further explanations.
Currently we have Jenkins that is running on-premise(VMware), planning to move into the cloud(aws). What would be the best approach to install Jenkins whether on ec2 or ECS?
Best way would be running on EC2. Make sure you have granular control over your instance Security Group and Network ACL's. I would recommend using terraform to build your environment as you can write code and also version control it. https://www.terraform.io/downloads.html
Have you previously containerized your Jenkins? On VMWare itself? If not, and if you are not having experience with containers, go for EC2. It will be as easy as running on any other VM. For reproducing the infrastructure, use Terraform or CloudFormartion.
I would recommend dockerize your on-premise Jenkins first. See how much efforts are required in implementation and administrating/scaling it. Then go for ECS.
Else, shift to EC2 and see how much admin overhead + costs you are billed. Then if required, go for ECS.
Another point you have to consider is how your Jenkins is architected. Are you using master-slave? Are you running builds contentiously so that VMs are never idle? Do you want easy scaling such that build environment is created and destroyed per build execution?
If you have no experience with running containers then create it on EC2. Before running on ECS make sure you really understand containers and container orchestration.
Just want to complement the other answers by providing link to official AWS white paper:
Jenkins on AWS
It might be of special interest as it discusses both options in detail: EC2 and ECS:
In this section we discuss two approaches to deploying Jenkinson AWS. First, you could use the traditional deployment on top of Amazon Elastic Compute Cloud (Amazon EC2). Second, you could use the containerized deployment that leverages Amazon EC2 Container Service (Amazon ECS).Both approaches are production-ready for an enterprise environment.
There is also AWS sample solution for Jenkins on AWS for ECS:
https://github.com/aws-samples/jenkins-on-aws:
This project will build and deploy an immutable, fault tolerant, and cost effective Jenkins environment in AWS using ECS. All Jenkins images are managed within the repository (pulled from upstream) and fully configurable as code. Plugin installation is automated, including versioning, as well as configured through the Configuration as Code plugin.
Regarding fargate - since it seems we can't run containers in privileged mode and also cannot mount /var/run/docker.sock, has anyone figured out a good solution for building/publishing docker images inside fargate tasks?
You probably want AWS Codebuild
I came upon this question after trying to run Jenkins builder slaves in Fargate. Previously they ran in ECS on EC2 instances with the docker.sock mounted.
I considered trying DinD but with Fargate currently having the maximum storage size of 10 GB I will abandon this idea for slaves. We would simply want to be able to cache more data before pruning or recycling the slave.
In my opinion storage size is also a factor when considering to build Docker containers in Fargate.
I am working on a project using a microservices architecture.
Each service lives in its own docker container and has a separate git repository in order to ensure loose coupling.
It is my understanding that AWS recently announced support for Multi-Container Docker environments in ElasticBeanstalk. This is great for development because I can launch all services with a single command and test everything locally on my laptop. Just like Docker Compose.
However, it seems I only have the option to also deploy all services at once which I am afraid defies the initial purpose of having a micro services architecture.
I would like to be able to deploy/version each service independently to AWS. What would be the best way to achieve that while keeping infrastructure management to a minimum?
We are currently using Amazon ECS to accomplish exactly what you are talking about trying to achieve. You can define your Docker Container as a Task definition and then Create an ECS Service which will handle number of instances, scaling, etc.
One thing to note is Amazon mentions the word container a lot in the documentation. They may be talking about the EC2 instance used for the cluster for your docker instances/containers.
