Guys I am trying to implement a 3-tier architecture to host a web app on aws.
The requirements given to me are as follows.
The app will leverage a 3-tier architecture:
A Web Server that will be running on S3
An application tier running on ECS Cluster on Fargate or a fleet of EC2s with ASG (your choice)
A data tier running on RDS Aurora PostgreSQL latest supported version
I understand perfectly what to do on the 2nd and 3rd instructions for the App and Database tier.
What I don't get is the “web server running on s3” . Is it possible to have a web server on S3?
What I know is, I can have a web server running on EC2.
Please, I need some explanation here.
Yes and no, S3 is a static file host, which means you have these HTML, CSS, and JS files where all you want to do is to send these files to the browser, then absolutely, yes. S3 can be used as a file serving service, https://docs.aws.amazon.com/AmazonS3/latest/userguide/WebsiteHosting.html
However, when you have the case where your website is doing some real-time HTML generation, something like SSR (Server Side Rendering), S3 won't cut it. S3 does not process the code in any way and only directly sends the files as-is to the frontend. In which case, you need a more traditional server on EC2/ECS/EKS.

Can some one please advise the steps required for migrating a web application which is currently running on tomcat server at onpremise to AWS ec2 instance. I understand this is not a straight forward and requires some detailed process.
The code is wrriten in Java and database used as oracle.
So it would be helpfull if someone can suggest me any relavent document or any website which gives some demo to refer me and proceed with this scenario.
If it's a personal project then I would recommend Lightsail as the simplest way to deploy existing Java application.
For a database a small instance of MySQL or if relational database is not needed then a document database like DynamoDB. https://aws.amazon.com/products/databases/?nc2=h_m1
There are multiple choices one how to migrate a Java application to AWS.
You could potentially use existing AWS services like:
Lightsail - https://aws.amazon.com/lightsail/
Beanstock - https://aws.amazon.com/elasticbeanstalk/
or
EC2 instance and install Tomcat manually
Use ECS with Docker https://aws.amazon.com/getting-started/tutorials/deploy-docker-containers/?nc2=type_a
As for Database solution Oracle is an option but quite expensive one.
When moving to AWS it's better to use one of the RDS managed databases like MySQL, Postgress or more expensive like Aurora.
In order to propose an architecture some details would be needed on predicted load, the size of the application and volume of data. Is the product regional or global, are there any additional issues that need to be addressed while moving to a cloud (performance, availability etc), how users are authenticated (are any other services needed).
Sorry I'm new to web server. I want to deploy a cloud server for user data:
User can login using web, with verification code sent to user's phone.
User can manipulate his data (add/modify/remove) when login.
Android/iPhone client can manipulate user data when login.
Server should have a database for storage, SQLLite or others.
It would be good to use Amazon/Ali-cloud cloud service, provided it can speed up my deployment. I'm not sure if I need run into blobs such as H5, PHP/JSP, node.js or others. Can you provide a guide for me, web link or book?
And, what's the most popular programming interface between Android/IOS app and cloud server? http post/get or other wrapper ?
Surely you can speed up your deployment using Amazon Web Services. This is my recommendation:
For Webserver,
Amazon EC2: Launch an instance where you can install Apache/Nginx
here. You will need a RDS instance running parallel with your server
which will lower your need on server CPU/Mem, but will cost also.
For Database, you can have many approach ways here:
Amazon RDS: Launch an instance where you host your Database
(mysql/...). This one will provide you with Database Name, Hostname,
Users, ... which you can use to connect with your webserver in EC2.
Your Android/IOS application can use RDS information for the database
connection.
Amazon DynamoDB: Fast, Flexible for NoSQL (wonder if you want to use
traditional database or NoSQL?): https://aws.amazon.com/amplify/
For Mobile/Website access control,
AWS Cognito: Great for user-accounts, designed for real-time data
model: https://aws.amazon.com/cognito/?nc1=f_ls
For serverless if you want to GET/PUT API on your webserver for
easier,
AWS Lambda: https://aws.amazon.com/lambda/?nc1=f_ls
Taking into account that you are just starting with your application, I would suggest going with serverless architecture with AWS Lambda running your business logic.
Key benefits:
No server management = spend time on building your application vs on maintaining infrastructure
Flexible scaling = scale based on what you really need
Pay for value = don't pay for resources that you don't need
Automated high availability = serverless provides built-in availability and fault tolerance
To learn more on serverless, you may want to check Building Serverless Web Applications - 2017 AWS Online Tech Talks.
Now when it comes to going deep, I would suggest checking online trainings available from acloud.guru, cloud academy, udemy or linuxacademy for serverless and also for the development language you want to use (Node.js is often used for such scenarios).
I have angular application with nodejs backend(REST API). I am confused with S3 and EC2. which one is better and what are the pros and cons deploying to each.Considering average load. Help will be highly appreciate.
I figured it out by myself.
S3 is used to store static assets like videos, photos, text file and
any other format file. It is highly scalable, reliable, fast, inexpensive
data storage infrastructure.
EC2 is a like your own server. And it is on Cloud so computing
capacity can be decreased or increased instantly as per server need.
So here my confusion is clear as ...
When we build Angular2 Application it generates .js files which called
bundle in term of angular2. Now, these files can be hosted on S3 Bucket. And can be accessed through CloudFront in front of it. Which is very fast cache enabled. And pricing model is pay per request.
But EC2 is like running own server. And we have to configure server it
self so for angular application it is not good. It is good for node
Applicationas it can do computation.
You can setup a popular ubuntu server in EC2 with
Nginx to serve your angular frontend and proxy request for your
NodeJs Api
S3 is a file storage mainly for serving static content and media files (jpg, fonts, mp4 etc)
Theoretically you can host everything in your EC2 instance, but with S3 it is easier to scale, backup, migrate your static asset.
You can probably start with one simple EC2 instance to run everything, when everything's working fine you can try move the static asset to S3
I only have 1 javascript file(bundle.js packed by webpack) and 1 html. It's kinda like SPA.
I'm thinking how I host this SPA? I already have one clean VM on Amazon EC2.
I was planning setup a docker (Nginx) on this EC2. However, as I said, this VM is clean. Only this SPA will use this EC2 VM.
So I'm confused by this situation. Should I use docker(nginx) or just install a Nginx on this EC2 for serving this SPA?
AWS S3 service is capable of service static files, You just need to upload your files to a bucket, then make them public and note the public URL.
As a side note, Containerizing apps and using microservices architecture, will give you advantages, Some of them are:
Ease of Upgrade
Fault Containment
Ease of technology change
Increased Security
Efficient Resource Utilization
S3 is cheap enough for static files, almost free compared to EC2 unless you have backend in place. You can use Cyberduck for S3 and if you want to go FTP one day, same app would give you a common UX for uploading your files.
Though Docker setup would be over engineering for static serving in IaaS, you would need to build an image that contains nginx and your files as in KyleAMathews/docker-nginx project.
Major newbie when it comes to Amazon EC2 servers, and web development in general.
At the moment I have a web app that is hosted on parse. Everything is done on the client side in the browser, and I want to change it to a client server model by writing a server in node.js.
I've looked into Amazon EC2, I've set up and instance and it looks good. My question is however:
Is there an easier way to update files on the instance? At the moment I'm pushing all the files from my computer to a github repo, then pulling them on to the instance- this seems very long winded. When using parse, all I needed to type was 'parse deploy' into the command line to update and deploy my application, is there something like this for Amazon EC2?
Thank you
I typically install or enable FTP on my ec2 instances and then just use the ftp client of my choice to update files.
