Is there any difference between a Web Application vs Worker tier/environment?
As in if I were to deploy a web application will it work (not that I will do that, but am trying to understand whats the difference)? I imagine I can install my worker service on a Web Application instance and have my app connect to that. If so apart from the name difference, what other differences are there?
According to AWS documentation of How Elastic Beanstalk Works: Architectural Overview.
When you launch an Elastic Beanstalk environment, you choose an
environment tier, platform, and environment type. The environment tier
that you choose determines whether Elastic Beanstalk provisions
resources to support a web application that handles HTTP(S) requests
or a web application that handles background-processing tasks. An
environment tier whose web application processes web requests is known
as a web server tier. An environment tier whose web application runs
background jobs is known as a worker tier. This topic describes the
components, resources, and architecture for each type of environment
tier.

I have a ASP.NET Core Web API planning to deploy in AWS, I don't have enough background in AWS what is the good package to subscribe in AWS?
My option is Amazon EC2 or Cloud Computing or there is other package for Web API? And my other concern is I also have files to upload by the client need at least of 1 or 2 TB of cloud storage. Can I connect the Cloud Storage services of Amazon to Amazon EC2. I really don't how to start.
You could look at Elastic Beanstalk (EB) as explained in Creating and deploying .NET applications on Elastic Beanstalk. EB is AWS Platform as a Service (Paas) offering which allows you to deploy your code, without managing much or any of EC2 instances, load balancers, security groups and more.
Alternatively, if you can run your app in a docker container, maybe it would be easier to deploy it using ECS Fargate. EB can also be used to deploy dockerized applications.
For storage you can use EFS if you require filesystem-like storage that can be shared across multiple instances, containers or lambda functions.
I am trying to deploy my Spring Boot microservices on using Elastic Beanstalk from AWS. It provides preconfigured environment for deployment. I have one Ubuntu machine with EBS with 80 GB(free tier option). I have some doubts. I am adding as points
When I am deploying using Elastic Beanstalk, where it actually deploying? In my EBS storage ? Or any other space which belongs to AWS ?
Is it possible to deploy anything without creating an EC2 instance? If possible, then where will it actually physical space occupy?
When I deploy my microservices, I choose Tomcat option. So under the box there is a sentence that Java Tomcat server environment is in Amazon Linux or something like that. I have Ubuntu machine; if Beanstalk using my EC2 instance, then why it showing message related to Amazon Linux 2017? Since my machine is Ubuntu?
And I found docs saying BeanStalk is not charging payments. Payment is going according to the AWS resources that we choose. So how I can relate this point with my 3rd point?
I'll start with #4 Elastic Beanstalk is a service you are NOT charged for, just the resources you consume, so EC2, EBS, ELB's.
When you deploy an Elastic Beanstalk application you select what version of Tomcat you want and with it the version of Linux
64bit Amazon Linux 2017.09 v2.7.2 running Tomcat 8 Java 8
64bit Amazon Linux 2017.09 v2.7.2 running Tomcat 7 Java 7
64bit Amazon Linux 2017.09 v2.7.2 running Tomcat 7 Java 6

#1 - It is deploying to an environment on EC2, which is why there is an AMI in the platform you provision.
When you launch an environment, you choose a platform configuration.
We update platform configurations periodically to provide performance
improvements and new features. You can update your environment to the
latest platform configuration at any time.
https://docs.aws.amazon.com/elasticbeanstalk/latest/dg/using-features.managing.ec2.html
#2 You can deploy your application on Docker, but that still needs EC2 hosts to run, you can manage them or you can use Multi Container platform, which provisions them to ECS .
https://docs.aws.amazon.com/elasticbeanstalk/latest
/dg/create_deploy_docker.html
#3 Elastic Beanstalk likes to keep resource under it's control, When you provision an Environment, it will provision the resources needed, no need to provision a machine outside of Elastic beanstalk.
You can create a custom platform if you want too based on Ubuntu.
Note
Modify the resources in your environment only by using Elastic Beanstalk. If you modify resources using another service's console,
CLI commands, or SDKs, Elastic Beanstalk won't be able to accurately
monitor the state of those resources, and you won't be able to save
the configuration or reliably recreate the environment. Out-of
band-changes can also cause issues when terminating an environment.
Some other points about Elastic Beanstalk from a great answer on Stack Overlfow
Have been running Docker with Elastic Beanstalk to deploy a relatively simple app, and it has been working great. Now with ECS on the horizon, I am interested to know what the differences are between the two services, and why one might use one over the other?
Amazon's documentation says the following:
Q: How is Amazon ECS different from AWS Elastic Beanstalk?
AWS Elastic Beanstalk is an application management platform that helps customers easily deploy and scale web applications and services. It keeps the provisioning of building blocks (e.g., EC2, RDS, Elastic Load Balancing, Auto Scaling, CloudWatch), deployment of applications, and health monitoring abstracted from the user so they can just focus on writing code. You simply specify which container images are to be deployed, the CPU and memory requirements, the port mappings, and the container links. Elastic Beanstalk will automatically handle all the details such as provisioning an Amazon ECS cluster, balancing load, auto-scaling, monitoring, and placing your containers across your cluster.
Elastic Beanstalk is ideal if you want to leverage the benefits of containers but just want the simplicity of deploying applications from development to production by uploading a container image. You can work with Amazon ECS directly if you want more fine-grained control for custom application architectures.
Does AWS Elastic BeanStalk support deploy non-web Java application to EC2?
That is to say, I want to pass a jar to EC2 instance, and make it auto run when EC2 instance started.
As of today, you have to run Java based web applications or worker tier applications, both have to be modeled as web apps.
You could run a tomcat app that does some backend processing work but does not perform the usual functions of a web app.
I keep killing the default instance and it keeps coming back. Why?
This answer is based on the assumption that you are facing a specific issue I've seen several users stumbling over, but your question is a bit short on detail, so I might misinterpret your problem in fact.
Background
The AWS Toolkit for Visual Studio allows you to deploy applications to AWS Elastic Beanstalk, which is a Platform as a Service (PaaS) offering allowing you to quickly deploy and manage applications in the AWS cloud:
You simply upload your application, and Elastic Beanstalk
automatically handles the deployment details of capacity provisioning,
load balancing, auto-scaling, and application health monitoring.
You deploy an application to Elastic Beanstalk into an Environment comprised of an Elastic Load Balancer and resp. Auto Scaling policies, which together ensure your application will keep running even if the EC2 instance is having trouble servicing the requests for whatever reason (see Architectural Overview for an explanation and illustration how these components work together).
That is, your Amazon EC2 instances are managed by default, so you don't need to administrate the infrastructure yourself, but the specific characteristic of this AWS PaaS variation is that you still can do that:
At the same time, with Elastic Beanstalk, you retain full control over
the AWS resources powering your application and can access the
underlying resources at any time.
Now that's exactly what you unintentionally did by terminating the EC2 instance via a mechanism outside of the Elastic Beanstalk service, which the load balancer detects and, driven by those auto scaling policies, triggers the creation of a replacement instance.
Solution
Long story short, you need to terminate the Elastic Beanstalk environment instead, as illustrated in section Step 6: Clean Up within the AWS Elastic Beanstalk Walkthrough (there is a dedicated section for the Elastic Beanstalk service within the AWS Management Console).
You can also do this via Visual Studio, as explained in step 11 at the bottom of How to Deploy the PetBoard Application Using AWS Elastic Beanstalk:
To delete the deployment, expand the Elastic Beanstalk node in AWS
Explorer, and then right-click the subnode for the deployment. Click
Delete. AWS Elastic Beanstalk will begin the deletion process, which
may take a few minutes. If you specified an notification email address
the deployment, AWS Elastic Beanstalk will send status notifications
for the delete process to this address.
