I have created a python notebook with many widgets connected to many dataframes and I can deploy it fine with Voilà on my local host. I would like to understand what is in the simplest way possible I can share the link with people on my internal network and also outside.
I read my articles suggesting to use Heroku, Binder (with GitHub), Google App Engine, PythonAnywhere...
So my question is what do you suggest for my needs? I would like to keep the interface generated with Voilà and I was hooping not to share it public or at least not to everyone.
Thank you
There are services which allow you to 'essentially' put your localhost on the web i.e. they allow people to remotely access a website hosted as localhost on your machine. I have personally used https://ngrok.io. I've also heard of localhost.run which is a recently launched service. With these services, you will get a URL that you can now send to the folks who you would like to access your service. If you do this, your local machine (the one hosting the service) has to be on.
You can also go with the option of deploying to a host like Google App Engine (GAE), PythonAnywhere, Heroku, etc. But you should add some form of authentication so that access is only granted to those who provide that authentication.

Hey,
I would like to start a small website that will be entirely handled in Python. I will be using the Flask framework for this. So far I had a lot of contact with AWS ECS and ELB service, but I admit, Python itself is still unknown to me. That's why I have a few questions:
1. I understand that from the point of view of a software engineer it is better to separate the backend and frontend - so it is best to create two separate Python projects based on Flask - one will be the API, the other the frontend, right? Generally, both should be separate services in the ECS service I guess.
2. In such configuration do they both have to use some kind of WSGI server, like gunicorn? Is this a good solution to run inside Fargate with multiple vCPU?
3. There are quite a few questions and myths around Nginx for this solution. Until now I assumed that if I use Application Load Balancer it should be enough (after all it also acts as reverse proxy). Is it necessary to use Nginx as a sidecar in ECS, are there any benefits of this? Assuming that using Nginx would be advisable, should it be only for the frontend or also for API?
Thank you really in advance for any supportive advice here - I know that I have asked for a lot of things.
In my consideration
1- if you want to have a microservice concept you can separate you application with front-end and back-end each of them has their freameworks. for front-end you can use Angular, React , Vuejs and so on. Python is backend technology and you can write strong restfull api to communicate with you front-end application
2- if you containerize your application with for example Docker and write Dockerfile for each service witch it is most common in microservice it is okay to run your container with any servers like nginx,apache or WSGI server(i did not work with this) then expose port (if it is needed) to be accessible
3- when you run your service in AWS Fargate it is possible to connect loadbalancer to your service and a service itself run tasks each task actually is one or more container with may be nginx server or something else , if you mean that it is normal to have nginx in your container.
I'm considering a suggestion to buy a Synology NAS server DiskStation DS720+:
https://www.synology.com/de-de/products/DS720+#specs
to run my python scripts or deploy web apps.
I am currently using heroku free account to deploy a web app.
I can't explain, why my web app delivers wrong output on heroku but works completely fine on my local computer.
No error message when deploying on heroku, eventhough the output is wrong.
Since I know nothing about NAS server, I want to ask if following tasks are possible with the diskstation:
Deploying Python Script and Web App (with Dash and Plotly as backbone)
Hosting dynamic website, not static website (like github pages)
Please pardon me, if these are silly questions, since this area is new for me.
The idea that these are possible and that I have my own cloud server is quite tempting.
Is there a better and more economical option for these purpose?
Thank you in advance for any inputs. Best regards, Gunardi Ali
The model you linked supports Docker, so that would probably be the easiest way to host dynamic websites such as Plotly dashboards.
However, if your apps are not generating the desired output when you run them on a machine other than your local computer then running them on a NAS might not work, either.
EDIT: Rereading your question, I would not suggest buying a Synology NAS if your primary use case is a web server. They are trimmed down for ease of use, but they come with their own set of limitations.
Depending on how resource intensive your applications are you might want to look at an Intel NUC or even a Raspberry Pi. If you plan to use the Synology's other features (file sharing, multi media, …) however, they are a great product.
My post has been considered as a duplicate, but this is not...
This question How to access mongodb on GCE with GAE does not answer to how can I edit firewall rules of GCE for an GAE application. It mentioned only about how can how to get te URI to set on an app running on GAE.
This is not my issue. I'd like to make a firewall rule for a deployed GAE application, I already have the external IP of my GCE set on my GAE app.
For example : on my GAE server I can make a dig to get the local server IP (for example : 35.187.8.45), so I can add it to my GCE firewall rules, then in my GAE shell I can make a "python main.py" and access to my mongodb on GCE.
But when I run a "gcloud app deploy", it does not run on the same server anymore. So I have to know on which one to edit a new firewall rules and allow the deployed application.
Hope to be clearer this time...
Well, I finally find a way to achieve what I wanted.
The way to go is to create a GAE flexible, thus, I can find under Instances my diffent VM which have an IP and add them to my GCE (where is my MongoDB) firewall rules.
What I understand of it, but maybe I'm wrong, is in flexible environement, application of GAE is deployed in several VM, running on compute engine, which is not the case for standard environement.
So, for people needs same, and doesn't want to expose their app to whole internet (0.0.0.0/0), go to a flexible environement
I am a newbie in web development, I am an energy engineering student trying to make a project, so I apologize if I say something weird.
I've made an application using Dash (python). And now, I would like to deploy that app in my server. I have a remote server (debian, adress.com, IP, opened ports: 80 and 443...) with my ssh public key and all the required stuff.
I have read all the official documentation in the plotly dash page, and also in flask's, but I dont understand very well the thing. I need either Heroku, OpenShift... And I dont understand very well how them work.
Could you please recommend me an easy tutorial (for dummies!) or give me advices/examples about the deployment? I would really apreciate I've searched the Internet a lot, but I can't figure it out.
You describe two options:
1. using your own server to host your app and
2. using a service which will host your app (heroku, etc.)
Using your own server to host your app
You need to decide for a web server, which is serving your page on your server. A host will not magically answer on any port. There is for example apache, nginx, etc... After having chosen one, you need to find a tutorial: how to run your flask app on [yourwebserver] or something like that.
Suppose you have chosen apache, you will find something like this:
https://jackhalpinblog.wordpress.com/2016/08/27/getting-your-python-3-flask-app-to-run-on-apache/
(In this case, you will have to figure out how to run your flask app with python3 instead of python2, if you are running debian)
When your page serves your page, you need an ssl certificate in order to make use of your domain. An easy way of doing this is https://letsencrypt.org/getting-started/ (there are probably other similar services)
Using a service, which will host your app for you (heroku, etc.)
Alternatively do not host you app on your own server, but on heroku, aws, gcd, etc., in my opinion this is much easier than hosting it on your own server. The documentation on hosting service websites is normally very good.
For heroku a good starting point would be here:
https://devcenter.heroku.com/articles/getting-started-with-python. Nevertheless the other services are easy to use as well, i just use this as an example.
I dont know if at all i make any sense, but this popped up in my mind. Can we use the 2gb free hosting of dropbox to put our django app over there and do some hacks to run our app?
No, it's not possible.
If you want to use dropbox as the hosting, you can put static pages, meaning just the html files with CSS and javascript because those files can be retrieved by doing a simple GET request.
Hosting a python code is not possible as it requires server side calculations & dropbox is just for saving files.
See the official wiki for the available hosts. https://code.djangoproject.com/wiki/DjangoFriendlyWebHosts
The point you need to understand is: can you run django without djagno installed? Can django be installed on a usb-drive? Dropbox is but a cloud storage service NOT cloud hosting service. To store you do not require RAM and processors while for hosting you do.
Hence the answer is NO. If you are okay with configuring apache etc. you can go for VPS. If not try some managed servers. If you dont want to spend much and are looking at free hosting solutions for django a few of them are:
kodingen.com
shellmix.com
http://0x2a-dc.com/index.php?name=shop&cat=6
http://www.heliohost.org/home/
http://bitnami.org/cloud
https://www.alwaysdata.com/

Yes its possible! PythonAnywhere.com offers that!
What pythonanywhere does is pretty simple. They integrate your dropbox account with their one. When you want to create a Django app, all you got to do is, direct the platform to store the app in your dropbox folder!
Now, you can open your Django app in your PC and edit it (wait for some time to sync)..restart the app, it works! I practically tried.
Tip: There are many cloud platforms which offer great services for free. Openshift, Heroku, Google App Engine are to name a few!
No, you can't use DropBox to serve a Django Website, as doing so requires Python code to be run, when DropBox is only for saving & serving files.
You can, however, find free hosting for your Django needs, among which:
Heroku, originally meant for Ruby hosting, but now allows you to do Python hosting. I didn't find it particularly easy to use with Django though.
ep.io, Python-specific hosting, but invite-only for the moment - it's possible to get an invite by sending an email, explaining your project & your needs though. Offers you free SSL on *.ep.io, which is pretty nice, and they've got great service.
Dotcloud, not platform specific, but my personal favorite. It's pretty easy to get started, and the CLI allows you to do a lot (but the downside is that you need it a lot too). If you're not afraid of CLI, it's great.
Being said its not possible from dropbox to do that you can use very simple cloud hosting as told ahead,
I might be late for answer but you can get free cloud hosting from Linux Fedora company called RedHat. Their cloud product is available for free which supports django hosting. I tried it my own
Openshift Free Cloud Hosting
In addition to what Thomas posted, some other options for free django hosting:
Amazon Compute Instance (free for one year, free sign up).
Google App Engine (free limits,django howto).
OpenShift (django howto).
