I'm new to these both technologies but have trouble understanding what exactly do these two do different, a use case example will be very helpful.
AWS ECS is the container orchestration service that allows deployment, scale of the containers. Let's say you have 10 apps to be deployed on EC2 machines. ECS will provide you an easy way to deploy and manage them, scale the app when needed etc.
Now, these 10 apps might want to talk to each other. One way is to use the ip address and make an RPC call to the other application. However, this process doesn't scale. What if the machine is restarted or the app or the app is moved to another EC2 machine etc.
So, you require a middleware that manages the mapping of app to the EC2 machine so that the application doesn't need to bother about how to call the other application.
AWS AppMesh provides exactly that middleware. It provides an application level networking so that your service can communicate with other services.
ECS - Platform to run containers as task/service in a clustered manner.
when multiple containers are running in an ecs cluster they may want to talk with each other OR other aws services. These containers should know where other containers/services are by means of ip/endpoint..etc. That's where service discovery comes into picture.
Appmesh - Appmesh is a service discovery tool plus a lot more feature. One of them is to ensuring reliable communication between containers.
Appmesh uses envoy as sidecar in ecs to implement service discovery(plus many more) functionality.
Most of the time Appmesh is used in conjunction with Aws CloudMap.
I have created a Spring cloud microservices based application with netflix APIs (Eureka, config, zuul etc). can some one explain me how to deploy that on AWS? I am very new to AWS. I have to deploy development instance of my application.
Do I need to integrate docker before that or I can go ahead without docker as well.
As long as your application is self-contained and you have externalised your configurations, you should not have any issue.
Go through this link which discusses what it takes to deploy an App to Cloud Beyond 15 factor
Use AWS BeanStalk to deploy and Manage your application. Dockerizing your app is not a predicament inorder to deploy your app to AWS.
If you use an EC2 instance then it's configuration is no different to what you do on your local machine/server. It's just a virtual machine. No need to dockerize or anything like that. And if you're new to AWS, I'd rather suggest to to just that. Once you get your head around, you can explore other options.
For example, AWS Beanstalk seems like a popular option. It provides a very secure and reliable configuration out of the box with no effort on your part. And yes, it does use docker under the hood, but you won't need to deal with it directly unless you choose to. Well, at least in most common cases. It supports few different ways of deployment which amazon calls "Application Environments". See here for details. Just choose the one you like and follow instructions. I'd like to warn you though that whilst Beanstalk is usually easier then EC2 to setup and use when dealing with a typical web application, your mileage might vary depending on your application's actual needs.
Amazon Elastic container Service / Elastic Kubernetes Service is also a good option to look into.
These services depend on the Docker Images of your application. Auto Scaling, Availability cross region replication will be taken care by the Cloud provider.
Hope this helps.
I am using AWS Elastic Beanstalk and have deployed my nodejs app on it. Now I want to automate this process i.e committing changes to Github and then automatically reflecting those changes in app. Now I have two options, use whether Elastic Beanstalk or using Code Deploy.
I have searched on both services,
I can automate using deployBot with elastic beanstalk or using
jenkins plugin for automation (AWS Elastic Beanstalk Deployment
Plugin) for elastic beanstalk.
Also found this link to automate:
https://aws.amazon.com/blogs/devops/building-continuous-deployment-on-aws-with-aws-codepipeline-jenkins-and-aws-elastic-beanstalk/
I can also use AWS CodeDeploy service for automation to deploy my app on EC2
instances using CodeCommit , code pipeline.
In case of code deploy I can also do by using this:
https://aws.amazon.com/blogs/devops/automatically-deploy-from-github-using-aws-codedeploy/
Now both services can be used , but which one is more suitable to use. That will automate my process whether using AWS Elastic Beanstalk or AWS Code Deploy.
The biggest difference is, that:
CodeDeploy is the service that deploys your application to the existing EC2 instance(s). It does not take into account LoadBalancing or scaling etc.
ElasticBeanstalk is more of the PaaS service, that provides you all the wrapping you need to scale your application so you don't need to worry about the DevOps aspect. Like monitoring, scaling etc.
I found this image to describe the differences nicely. Including as well OpsWorks:
If you want to read more about differences of CodeDeploy, Elastic Beanstalk or OpsWorks, check out AWS own document: https://d0.awsstatic.com/whitepapers/overview-of-deployment-options-on-aws.pdf
The answer is very simple. ElasticBeanstalk offers cookie-cutter automated deployments based on a set of AWS common practices. CodeDeploy is broadly configurable and customizable.
You should use ElasticBeanstalk until you find a use case that cannot be resolved without using CodeDeploy (two use cases suggested by the AWS Documentation posted by Maksim Luzik are deploying to EC2 instances managed internally by your organization and deploying to EC2 instances for third-party integration).
Use the second option instead of using third party tools as AWS platform is supporting to deploy your app using git or bitbucket using python based scripts.
I have worked with both tools and both are great for respective jobs. I found ElasticBeans task convenient but lesser flexible when It comes to work with custom platforms.
I am using codeDeploy in my current application. I decided so because of following use cases.
I am using debian based platform. Elastic BeansTalks does not offer that platform in its default list of available platforms. So what's the point if I need to create custom AMI.
I I have 2 type of applications built on the top of same code base. One is Web and other executes couple of queues in the background. I need to release same code on both type of applications so that's why I found codeDeploy does better job.
I am evaluating a few "cloud monitoring" tools. What ready-made complex applications can I deploy to AWS, to evaluate these tools? I am looking for something which automatically creates a multi-node LAMP stack, for example, or a Hadoop/Spark cluster.
EDIT: as an example, I'm looking for something like CloudSuite, but that is meant to be deployed in a multi-host environment.
I am not aware of any premade complex setups that are turnkey and ready to go. They all take some configuration.
You can setup some preconfiured LAMP servers from BitNami:
LAMP powered by Bitnami
You can then cluster them via an Elastic Load Balance and connect them to a RDS instance for few hours and run tests.
You can also review the AWS Quick Start Reference Deployments
Another option would be to use CloudFormation Sample Templates to automate the setup of common services.

I have developed a .NET MVC application and have started playing around with AWS and deploying it via the Visual Studio Toolkit. I have successfully deployed the application using the Elastic Beanstalk option in the toolkit.
As I was going over the tutorials for deploying .NET apps to AWS with the toolkit, I noticed there are tutorials for deploying with both Elastic Beanstalk and CloudFormation. What is the difference between these two?
From what I can tell, it seems like they both essentially are doing the same thing - making it easier to deploy your application to the AWS cloud (setting up EC2 instances, load balancer, auto-scaling, etc). I have tried reading up on them both, but I can't seem to get anything other than a bunch of buzz-words that sound like the same thing to me. I even found an FAQ on the AWS website that is supposed to answer this exact question, yet I don't really understand.
Should I be using one or the other? Both?
They're actually pretty different. Elastic Beanstalk is intended to make developers' lives easier. CloudFormation is intended to make systems engineers' lives easier.
Elastic Beanstalk is a PaaS-like layer on top of AWS's IaaS services which abstracts away the underlying EC2 instances, Elastic Load Balancers, auto-scaling groups, etc. This makes it a lot easier for developers, who don't want to be dealing with all the systems stuff, to get their application quickly deployed on AWS. It's very similar to other PaaS products such as Heroku, EngineYard, Google App Engine, etc. With Elastic Beanstalk, you don't need to understand how any of the underlying magic works.
CloudFormation, on the other hand, doesn't automatically do anything. It's simply a way to define all the resources needed for deployment in a huge JSON/YAML file. So a CloudFormation template might actually create two Elastic Beanstalk environments (production and staging), a couple of ElasticCache clusters, a DynamoDB table, and then the proper DNS in Route53. I then upload this template to AWS, walk away, and 45 minutes later everything is ready and waiting. Since it's just a plain-text JSON/YAML file, I can stick it in my source control which provides a great way to version my application deployments. It also ensures that I have a repeatable, "known good" configuration that I can quickly deploy in a different region.
For getting started quickly deploying a standard .NET web-application, Elastic Beanstalk is the right service for you.
AWS CloudFormation: "Template-Driven Provisioning"
AWS CloudFormation gives developers and systems administrators an easy way to create and manage a collection of related AWS resources, provisioning and updating them in an orderly and predictable fashion.
CloudFormation (CFn) is a lightweight, low-level abstraction over existing AWS APIs. Using a static JSON/YAML template document, you declare a set of Resources (such as an EC2 instance or an S3 bucket) that correspond to CRUD operations on the AWS APIs.
When you create a CloudFormation stack, CloudFormation calls the corresponding APIs to create the associated Resources, and when you delete a stack, CloudFormation calls the corresponding APIs to delete them. Most (but not all) AWS APIs are supported.
AWS Elastic Beanstalk: "Web Apps Made Easy"
AWS Elastic Beanstalk is an easy-to-use service for deploying and scaling web applications and services developed with Java, .NET, PHP, Node.js, Python, Ruby, Go, and Docker on familiar servers such as Apache, Nginx, Passenger, and IIS.
You can simply upload your code and Elastic Beanstalk automatically handles the deployment, from capacity provisioning, load balancing, auto-scaling to application health monitoring.
Elastic Beanstalk (EB) is a higher-level, managed 'platform as a service' (PaaS) for hosting web applications, similar in scope to Heroku. Rather than deal with low-level AWS resources directly, EB provides a fully-managed platform where you create an application environment using a web interface, select which platform your application uses, create and upload a source bundle, and EB handles the rest.
Using EB, you get all sorts of built-in features for monitoring your application environment and deploying new versions of your application.
Under the hood, EB uses CloudFormation to create and manage the application's various AWS resources. You can customize and extend the default EB environment by adding CloudFormation Resources to an EB configuration file deployed with your application.
Conclusion
If your application is a standard web-tier application using one of Elastic Beanstalk's supported platforms, and you want easy-to-manage, highly-scalable hosting for your application, use Elastic Beanstalk.
If you:
Want to manage all of your application's AWS resources directly;
Want to manage or heavily customize your instance-provisioning or deployment process;
Need to use an application platform not supported by Elastic Beanstalk; or
Just don't want/need any of the higher-level Elastic Beanstalk features
then use CloudFormation directly and avoid the added configuration layer of Elastic Beanstalk.
Cloud Formation is a service that lets you deploy AWS services. You create a template file that describes which services you want. When you deploy that template, Cloud Formation creates the resources for you as a "package". All the resources you defined in your template are started and terminated together. Examples of types of resources that can be created with Cloud Formation are: S3, EC2 instances, AutoScaling, DynamoDb, etc. For EC2, Cloud Formation also gives you the ability to make use of "cfn-init" scripts; which can be used in conjunction with the template to boot strap your instances.
Elastic Beanstalk uses Cloud Formation templates and scipts to: 1. Create a Load Balancer and Auto Scaling Group, 2. Copy your code to S3, 3. Bootstrap an Ec2 instance to Download the code from S3 and deploy it.
Cloud Formation is not as easy to use as EB, but it is much more powerful, because you can create resources other than EC2 instances, control how the cfn-init script, and etc.
There are other differences worth noting. Elastic beanstalk is designed as a container for a single app. I've a set of several websites and services but found it very difficult to deploy multiple websites with beanstalk and was advised, after several attempts, by AWS help to use cloud formation in this situation as it has the extra flexibility.
Theres a really helpful article on bootstrapping AWS cloud formation and updating a running site here thats much clearer than the AWS pages. Still trying to work out if we can deploy from VS straight to the cloud formation template stored on S3 and get it to auto update like beanstalk...
These services are designed to complement each other. AWS Elastic Beanstalk provides an environment to easily deploy and run applications in the cloud. It is integrated with developer tools and provides a one-stop experience for you to manage the lifecycle of your applications. AWS CloudFormation is a convenient provisioning mechanism for a broad range of AWS and third party resources. It supports the infrastructure needs of many different types of applications such as existing enterprise applications, legacy applications, applications built using a variety of AWS resources and container-based solutions (including those built using AWS Elastic Beanstalk).
AWS CloudFormation supports Elastic Beanstalk application environments as one of the AWS resource types. This allows you, for example, to create and manage an AWS Elastic Beanstalk–hosted application along with an RDS database to store the application data. In addition to RDS instances, any other supported AWS resource can be added to the group as well.
Both are for provisioning infrastructure; but they differ in their approach.
Beanstalk: The starting point is the code. I have a NodeJs code I want to upload & run it; please provision the infrastructure for me. (PaaS) Platform as a Service
CloudFormation: The starting point is the infrastructure. Please create an EC2 instance, with one LoadBalancer, Security Group etc so that I can uploaded my NodeJs code to it. Infrastructure as Code (IaC).
Elastic Beanstalk automatically handles the deployment, from capacity provisioning, load balancing, auto-scaling to application health monitoring based on the code you upload to it, where as CloudFormation is an automated provisioning engine designed to deploy entire cloud environments via a JSON script.
Beanstalk: Gives the developer the ability to manage only code and not systems
Cloud Formation: Simplifies and makes everything easier for a Systems Engineer
If a developer or the dev team is looking for a quick MVP testing, the best option is to quickly get deployed with Beanstalk and check.
When a AWS migration happens, systems engineer will get involved in provisioning and Cloud Formation will help a lot and give much more granular control.
Beanstack internally uses cloudformation.
Beanstalk - Basically helpful for software developers.
Example : You want to start the PC quickly and run an application. You don't buy the PC items (harddisk, ram, Processor) separately. You buy a whole CPU or a laptop of a required config. You dont care how its running inside as you want your application to run for you. Beanstalk gives you this feature of everything ready made with no worries.
Cloudformation - Basically helpful for system engineer/ Hardware.
Example : You want to assemble 100's of PC's and give it to the developers then instead of assembling so many PC's you can just give a list of items and the PC is assembled for you by the retailer.
Similarly create a template and send it to cloudformation it will finish your work with no effort.
