Hello everyone,
Like a lot of us, I’ve started working with serverless: https://serverless.com/
I’m thinking, are there bits and pieces of meteor that could be “outsourced” to a serverless script, for better scalability?
For example, is the computing power required for oplog-tailing possible to shift to a serverless architecture?
Perhaps the whole topic is moot, I don’t know, but I’m curious 
Oplog tailing is not possible to be made serverless, and it does not make much sense, I believe. And it’s not the use case for a severless function, I think it would be very expensive also (even though in general severless is cheaper).
CRON jobs, email sending, webhooks, and server side routes are all the things you could go serverless. All kind of microservices could be serverless while your meteor app serves only the client and app related operations.
Maybe even methods, but I’m not sure of the benefits if it’s not a heavy workload method (like PDF generation).
The oplog tailing can be replaced by the great redis-oplog.
By the way, we use serverless (AWS Lambda, S3 and API Gateway) but to go full serveless may not be the best option too (as everything, it depends).
