Is there any utility to manage content for eLearning site? - amazon-web-services

Is there a tool available that can help manage (create courseware, upload etc) training content on AWS and provide apis to access the training content? Training material consist of audio and video files

Try Articulate 360. They offer both online and downloadable development tools. You can create, store, share, have SMEs validate content. They even have an integrated LMS. Video development etc. I use this product for my eLearning development on a daily basis.

can we use Exoplayer for Websites?

I am working on an AWS cloud project which involves video streaming. For this case, a media player needs be to used is Exoplayer along with required AWS services but I am not able to find anything regarding Exoplayer's use on Websites. Can anyone help me with the usage of Exoplayer for web applications?
ExoPlayer is an Android player - for websites, you would typically use a HTML5/JavaScript player assuming your service is using a typical video streaming technology such as HLS or DASH.
OpenSource HTML5/JavaScript players are readily available:
https://github.com/videojs/video.js
https://github.com/shaka-project/shaka-player
There are also multiple commercial players also like BitMovin, TheoPlayer, JWPlayer etc.

Planning an architecture in GCP

I want to plan an architecture based on GCP cloud platform. Below are the subject areas what I have to cover. Can someone please help me to find out the proper services which will perform that operation?
Data ingestion (Batch, Real-time, Scheduler)
Data profiling
AI/ML based data processing
Analytical data processing
Elastic search
User interface
Batch and Real-time publish
Security
Logging/Audit
Monitoring
Code repository
If I am missing something which I have to take care then please add the same too.
GCP offers many products with functionality that can overlap partially. What product to use would depend on the more specific use case, and you can find an overview about it here.
That being said, an overall summary of the services you asked about would be:
1. Data ingestion (Batch, Real-time, Scheduler)
That will depend on where your data comes from, but the most common options are Dataflow (both for batch and streaming) and Pub/Sub for streaming messages.
2. Data profiling
Dataprep (which actually runs on top of Dataflow) can be used for data profiling, here is an overview of how you can do it.
3. AI/ML based data processing
For this, you have several options depending on your needs. For developers with limited machine learning expertise there is AutoML that allows to quickly train and deploy models. For more experienced data scientists there is ML Engine, that allows training and prediction of custom models made with frameworks like TensorFlow or scikit-learn.
Additionally, there are some pre-trained models for things like video analysis, computer vision, speech to text, speech synthesis, natural language processing or translation.
Plus, it’s even possible to perform some ML tasks in GCP’s data warehouse, BigQuery in SQL language.
4. Analytical data processing
Depending on your needs, you can use Dataproc, which is a managed Hadoop and Spark service, or Dataflow for stream and batch data processing.
BigQuery is also designed with analytical operations in mind.
5. Elastic search
There is no managed Elastic search service directly provided by GCP, but you can find several options on the marketplace, like an API service or a Kubernetes app for Google’s Kubernetes Engine.
6. User interface
If you are referring to a user interface for your own use, GCP’s console is what you’d be using. If you are referring to a UI for end-users, I’d suggest using App Engine.
If you are referring to a UI for data exploration, there is Datalab, which is essentially a managed notebook service, and Data Studio, where you can build plots of your data in real time.
7. Batch and Real-time publish
The publishing service in GCP, for both synchronous and asynchronous messages is Pub/Sub.
8. Security
Most security concerns in GCP are addressed here. Which is a wide topic by itself and should probably need a separate question.
9. Logging/Audit
GCP uses Stackdriver for logging of most of its products, and provides many ways to process and analyze those logs.
10. Monitoring
Stackdriver also has monitoring features.
11. Code repository
For this there is Cloud Source Repositories, which integrate with GCP’s automated build system and can also be easily synched with a Github repository.
12. Analytical data warehouse
You did not ask for this one, but I think it's an important part of a data analysis stack.
In the case of GCP, this would be BigQuery.

Google Apps - Data Transfer API - transfert only some ressources

I'm trying to use the new Data Transfer API for Google Apps Domain and I would like to transfer some specific Google Drive files from one user to another. It seems we can use this API to transfer a "full service" (eg: all files from Google Drive) and not only some specific files.
Is my understanding of this API is correct or is it possible to limit the transfer to specific resources?
Thank you.
You're correct. The API enables you to transfer ownership of application data (currently Drive documents and Google+ pages) in bulk. It essentially allows you to automate the manual ownership transfer task documented here. You might want to read this blog here which has some useful background information.
The only way to achieve what you want is to use the Drive API (not to be confused with the Drive SDK).

On the fly Stream and transcode video with Django

I have a model that uses "models.FileField()", which I then display back to the user so they may click the link and have a file rendered in their browser. The user can upload various types of files.
Problem is, I'd like to handle large avi's differently, and have the file stream to the user.
The requirement I have is to simply stream/transcode video files from the media_root dir to an end user's browser, preferably in a mac friendly format. It would be for a couple users at most.
I've search and stumbled upon a few projects:
https://github.com/andrewebdev/django-video
https://github.com/rugginoso/django-transcodeandstream
As I am I a relatively newbie when it comes to django, I'm not sure how to incorporate their code into my proj.
Any thoughts, suggestions?
You can check Amazon Elastic Transcoder. It is a media transcoding in the cloud. It is designed to be a highly scalable, easy to use and a cost effective way for developers and businesses to convert (or “transcode”) media files from their source format into versions that will playback on devices like smartphones, tablets and PCs.
Or else you can check Webfaction, they have Video and image processing on their servers which you can use.
If you will use any of those, you can ask them about the installing process and how to integrate it in your project.
And one more thing, if you want to play the video on the browser, you will need a video player like jwplayer.
Hope this will help you get started! Best wishes!

Akamai Integration

I want to use Akamai to store files. I want to know whether Akamai provides any API (e.g. web services) for us to upload, download, list files? Appreciate if anyone could provide some documents for a newbie.
Another question is, if I upload video files to Akamai, does it provide video streaming capability?
Akamai provide an API to allow your customers to download files.
From their web site it is called "Client-side Downloads"
Client-side Downloads offers the ability to offload a significant
portion of edge delivery onto a managed and secure network of clients
- using client-to-client delivery - to provide a lower cost download
solution that respects the clients. Good uses may include software
downloads, patches, and updates, background software and drivers, and
downloadable video and games used by about a thousand or more people.

Here is further detail on how to interact with their API

I was at their presentation the other day and they spoke about a Video Stream product coming out mid to late 2012.
I ran into another company that did video hosting and streaming called Movideo
