In Google PubSub Quotas section, it states that project can have no more than 10,000 subscriptions. Am I understanding this correct that even if i have 100 topics, then I can just have total of 10,000 subscriptions in overall? If this understanding is correct and if Google PubSub is so much scalable, why there is such low limitation?
The service is scalable in terms of throughput. The throughput quotas do have an initial default, however they can be raised by request.
It's true the service will not scale to support your presumed use case of delivering messages directly to users, which could easily exceed 10,000 subscribers across all topics. Nevertheless, the service is not designed for this use:
Cloud Pub/Sub is intended for application and system integrations
rather than direct communication with end-user interfaces
If you need to support user subscriptions:
For this type of
client-server communication, you can use Firebase Cloud Messaging,
Cloud Platform's solution for sending push notifications to multiple
mobile devices.

Is it possible to use the WhatsApp business API to communicate with users and also allow them to forward content from WhatsApp directly to our application. For example enabling Web-hooks for different WhatsApp channels to receive the messages from those channels. If yes, can someone guide me how can we implement this feature? and how can we authorize those channels with our WA business account
Finding sources/documentation for developing needed feature
Whatsapp API allows you to Broadcast messages to Unlimited Users, automate notifications, integrate Chatbots, provide Live Chat on Multiple devices and many more functions. Install the WhatsApp Business API Client and then Install your API client. Once your client is working, you can update your application settings. Start using the client, Register your phone number with an API call to /account and send a test message with a call to /messages . let me know if u find this helpful.
Yes, it is possible. The WhatsApp Business Platform allows medium and large businesses to communicate with their customers at scale. Using their APIs, businesses can connect thousands of agents and bots to interact with customers programmatically and manually. Additionally, the APIs can be integrated with numerous backend systems, such as CRM and marketing platforms
Here is the link for the documentation: https://developers.facebook.com/docs/whatsapp/overview
Link for different types of webhooks:

There are multiple ways given in the documentation. But keep in mind, do read the documentation carefully, they have their updated and the previous version so use them as per your requirements.
In Firebase Cloud Messaging, Messaging report, count of received messages is more then sent. Why it is so ?
I have checked data in Biq Query and it differs with diagram. In Big Query data count of received messages is less then sent.

That data is unusual since normally send count should be greater than received. It’ll be challenging to pinpoint or even narrow down what could be the problem on a public forum without going into project-specific details. The issue can be in the FCM backend itself or just in the reporting metrics. I would recommend reaching out to Firebase support as they can offer personalized help.
I am developing an app where I want to send notifications to multiple users from my backend server. These notifications will contain 4 different contents, three of them will go to 3 different users, but the forth one will go to more than 1000 users, the frequency of theses messages will be 3 to 7 times a week. Is it ok to send this amount of messages one by one using the Cloud Messaging api? Or should I group the messages before sending?
I thought about creating a topic in the Cloud Messaging, and subscribe the users to it and then send a message, but I don't if it is correct to keep subscribing/unsubscribing users just to send one message.
NOTE: I've never used any push notifications service before.
The Firebase Cloud Messaging infrastructure delivers billions of messages per day. The volume you're describing sounds well within reason for it.
Without knowing more about the use-case it's hard to say whether using a topic would be a better approach, so I recommend reading the documentation on topic messages to get a better understanding for it.
I provide SES Services to many of my clients in different regions of the world. So their apps send out emails through my AWS SES account. It has become a problem to trace out how to measure their usage and stats, IAM wise or some other ways and then be able to bill them for what they have consumed. There must be a way to break stats into some kind of Sub Accounts or something
Can someone help regarding this ?
You have two options for such fine-grained monitoring, according to the official docs:
Feedback notifications
This option allows the most detailed reporting for your billing needs. However, it also requires more work on your part, because you need to build handlers (i.e. lambda functions) which will log sending/bounces/complaints in some persistence (i.e. DynamoDB table). More details here.
Event publishing
This option uses CloudWatch for persistence and you have the (probably) familiar CloudWatch UI for reporting. You will have to enforce (somehow) your clients to use a AWS specific SMTP header or SendEmail / SendRawEmail API calls. Less work on your part but you need to find a way to make your clients help you. More details here.
We're writing an app like LINE, and need notification service for each single message in a chat group when app is in background.
We try to use Firebase Cloud Messaging for this feature, but I can't see a reasonable implementation.
Topic subscribing is too slow for "create a topic for each chat group" since it takes hours to create one. Device group messaging is designed for devices owned by a single user. Using sending to a single device feature for each receiver and each message does not seem to be practical since the server loading is too heavy.
Is there a good way to use FCM making such app, or do I need to find another service? Thanks.
