I am currently making an IoT device with an App. I had hired freelancers to make that App using Google Firestore since my IoT hardware is also connected to Firestore. The app was made using flutter and uses Firebase Authentication as well.
However, it has been suggested to me that AWS is a better solution for my IoT device, particularly because we were able to successfully connect our hardware to AWS, which was difficult for us to do using Cloud Firestore.
Now the challenge is: to change the App database. Since the project is at a nascent stage, our team can afford to use take some time to migrate from Firebase to AWS.
But my question is: how easy will it be for an app developer to change the database of an App that is partially made?
"Partially made" so I'm guessing the app is not in production. This reduces the difficulty.
Things that make migration hard.
Different types of database. If the aws database is not NoSQL (firestore is NoSQL), the difficulty is increased.
Data structure. Are the both data structures the same? if no, your developers will spend sometime transforming the data to the new structure.

I have a personal website hosted on aws using s3, cloudfront and route53, but as time goes by I would like to have some dynamic functionalities such as allowing visitors to leave a private message. May I know what is the best option for me? Should I use an EC2 instance? Or Lambda + API gateway... etc?
Any suggestion is appreciated, thanks!
I would recommend that you start at Choose Your Web Application Infrastructure because there is no single answer.
There are different factors to take into account when deciding which service to use to deploy your first web application on the AWS Cloud. You should consider if you want a managed infrastructure with low stress, if you need containers (and why) or if you want full control and customization.
As I think you currently don't have server-side rendering type of setup that is great news for you to host a personal website, For any dynamic backend related stuff you can use AWS Lambda functions for contact forms submissions and other things and the price would also no very low to host these rather than switching to ec2

A video player sends the server log data about what the user has been doing (start, pause, play, playing, etc.)
Sending the logs to the server and storing them in the DB, then running queued jobs to calculate stats on these has worked... okay, so far.
It's clear there should be some sort of optimization here. What services provide the best custom log storage?
What would be the best manual option? Considering running some Lambda functions and storing in AWS (RDS?) manually, but wondering if the maintenance of such a service is warranted.
I would store the logs in AWS S3 (Storage) and then use AWS Glue (Transform) and AWS Athena for ad-hoc querying of different stats, this will still work out cheaper than using a traditional database approach plus it has a lot of other advantages.

I have a webapp running with Django. I would like to make an Enterprise Edition of this website. In exchange for a yearly fee, I would like to allow companies to host the webapp on their own server and benefit from unique features
The problem is that I have no idea how to proceed. How can I execute this, without sending my whole code over to their computer and launching the django app there?
Is there something like generating an .exe that would run the django app without sending my code? How do companies usually proceed to make their tools available on another company's intranet?
well I haven't heard something like that, but what you can do is using a license in your code, there are many types of licenses, from open source to trade secret license, read more about it

I am looking to build a webapp to improve user experience in booking railway tickets in India. The API is impossible to get due to hefty charge to procure it. I have seen many apps that provide details of the trains etc through their apps.
My Question is how are they scraping data from the website.In general how can I legally get data shown to user (I don't want payment and stuff that are impossible without API) on any website. How do people scrape such data? Any tools/methods?
Bear with me if question is naive. I'm pretty new to this stuff.
They can get the train schedule information using any one of several programming languages though it is most likely done with ordinary PHP and any good webserver host. For example all indian train schedules can be found on the indianrail.gov website.
Sending a specially built URL to ..
http://www.indianrail.gov.in/cgi_bin/inet_trnnum_cgi.cgi?lccp_trnname=1123
using the POST method of sending form data should give you all the details for train number 1123 After that it becomes just a simple task of tidying up the results for storage in a database.
Update: well armoured site its checking both the user agent and referer of inbound requests.
Ammendum: the indianrail.gov site is changing to http://www.trainenquiry.com/ -> will have to take another look

I have read a couple articles and I know the basic concept of cloud computing..But I still don't know what exactly I can do with this service.
As a mobile application developer, I have developed a couple of iPhone applications. I have a Bluehost account and I have MySQL database in there. I have a couple PHP scripts on my server and on device side, it sends http request to the server to get the data from database in XML format. That is basically how I designed and implemented my applications..
Now what can I do with a cloud computing? If I use a cloud computing service such as AWS then how it is going to change the structure of my application?
Thanks in advance...
Cloud computing doesn't necessarily have to change the structure of your app. The main benefit of cloud computing in a lot of cases is scaling.
Right now if your iPhone apps become really popular and overload your current host, what do you do?
Using the cloud, you could spin up new instances (servers) on demand almost instantly. Another benefit is you only pay for what you need. Of course, depending on the situation, it might require changes to your structure to take advantage of scaling features.
edit: Specific to AWS, they have a service called Elastic Load Balancing. Take a look: http://aws.amazon.com/elasticloadbalancing/
