Why Elastic beanstalk restore to old version - amazon-web-services

why Elastic beanstalk restore to old version in AWS.
i try to deploy simple leraval project to aws.

Elastic Beanstalk is a service that makes it easy to deploy, run, and scale web applications and services on the Amazon Web Services (AWS) platform. When you deploy your application to Elastic Beanstalk, it creates an environment for your application and manages the details of the infrastructure and application components for you.
In some cases, Elastic Beanstalk may automatically restore your application to a previous version if it detects that the new version you are deploying is not working correctly. This can happen if the new version is not compatible with the environment or if it is causing errors. Restoring to a previous version can help prevent downtime or other issues with your application.
It is important to carefully test your application before deploying it to Elastic Beanstalk, to ensure that it is compatible with the environment and will run smoothly. This can help prevent issues like an automatic restoration to a previous version

how to deploy MEAN stack app on AWS elastic beanstalk?

I'm trying to deploy my mean stack app on AWS using elastic beanstalk but there doesn't seem to be a tutorial good enough that can help me through it.
I would also like to know if I should really deploy it on elastic beanstalk or Lightsail?
Can you share any articles, videos or anything good enough to help me. It will be helpful to a lot of people.
Angular Version : 7
Node Version: 10.14.1
elastic beanstalk will be the option for production while you can use light sail for testing dev enviroment
now if we talk about the deploying Mean stack app
Open Elastic Bean stalk console and you will get option to choose Webserver
Choose web server with apache, tomcat, nginx, configure it as per your requirement
at last you will get option for upload your application
Upload your app using zip file (if dist folder is output then direct deploy dist in elastic beanstalk)

Changing Docker engine version on AWS Beanstalk

I have an application I want to deploy as a Docker container using Amazons Beanstalk platform. However the application is only certified against v17 of Docker, but Beanstalk uses v18 of Docker.
Is there a way of configuring Beanstalk to use a specific version of Docker? I cannot find any options to do this when I create my application within the AWS console (I have signed up for a free account so maybe such an option is for paid versions).

Deploying a web application for Selenium testing on AWS EC2

I have a web application that uses Selenium in backend to run few scripts when invoked by user. I want to deploy this web app on AWS.
Here are my findings so far:
I can have a windows EC2 instance created and then I can install tomcat, firefox and all the necessary stuff. Then using putty or any other client, I can deploy my war and start tomcat.
I can directly make use of Elastic Beanstalk and deploy my war file there itself but then, there is no windows EC2 available for beanstalk and I don't know how to install firefox there and make my application work.
What is the best way to achieve this and what steps should I follow. I want to install a specific firefox version to be able to make it run with my selenium scripts.
There are two separate things here:
Deployment of web application on AWS cloud
Run the selenium tests against your web application
According to me, you should first think of deploying a web application to AWS cloud. There are many ways by which you can get it deployed to AWS cloud with below services:
Spin a new AWS EC2 instance, install all required software and deploy the web application.
Use AWS elastic beanstalk service with either with tomcat or docker.
Use AWS ECS if you prefer docker
According to me, second option will be quick for you with tomcat environment option. If you select tomcat environment, then your platform will be Tomcat 8 Java 8 on 64bit Amazon Linux.
Now, here comes the second part. You can have below options for your browser environments.
Spin a new separate AWS EC2 instances with correct AMI and install your specific browsers on these instances.
If you prefer SaaS, then you can take a look at browserstack or SauceLabs for remote environment.
If you have CI(jenkins/travis/Circle CI), then make use of that infrastructure to luanch your tests with either option from the above.

Hosting web services project in Amazon

Hi We have built a java based web services project with using jboss server. How do I host this application with Amazon cloud? This web services act as back end for a mobile android app.
I am looking for PaaS option of Jboss server and Postgres database. I could create a postgres database. But could not find Jboss server.
My understanding is in PaaS, Jboss and Postgres should be able to scale up itself as per demand.
Another option provided by Amazon is EC2 as far as I have understood. But if I go with EC2, I will have install and set up jboss and postgres on my own. Then does it scale up by itself as per demand?
Please guide.
If you want to deploy your web application to AWS and ensure its scalability, you have basically two options:
EC2 instance [IaaS] - The disadvantage is, as you mentioned in your question, that you have to configure everything manually. Some external mechanism for scaling has to be used. Amazon provides its AutoScaling service which can be configured to launch new EC2 instances based on utilization or some other metric.
Elastic Beanstalk [PaaS] - This service has the auto-scaling already built in and manages the EC2 instances with your application on its own (it takes care about launching them, deploying the app etc). The disadvantage is that JBoss server is not support at the moment (you would have to switch to Tomcat).
There is a way, how to make JBoss work on Elastic Beanstalk, however. ELB has newly added the support for Docker so if you make your JBoss API run in Docker, you can deploy it to ELB and scale it without much effort and configuration.
As for the database, mentioned in your question, Amazon has plenty of choices, Postgres included, in their RDS service.

AWS ElasticBeanstalk in a production environment

I wonder about the choice of AWS Elastic Beanstalk as an environment for the production system. Do you have some experience in this regard?
More info as I have been using EB for more than 8 months...
So far so good, elastic beanstalk has its limitation though.
It is designed for service handling, but when you just want a processing unit, you need to do something additional for ELB and autoscaling.
Fixed in latest release: No VPC yet, so your Elastic Beanstalk is still exposed to the internet., but VPC support is limited and need manually config through config files.
Fixed in latest release: Not easy to customize the webserver (e.g. tomcat) you have to use your own images.
Limited tuning option on the webserver parameter.
From my experience, reliability is OK not great, the main problem is the EB automation scripts sometime can stuck you environment.
But overall I like it.
We deployed our Java webapplication (all three environments) Beta, Staging and live on ElasticBeanStalk. They are doing well, so far we haven't faced any issues with Elastic Beanstalk.
