How can you optimize your application for infrequent peak loads?

Question

Software design

There is a mobile application, now there are not so many users, but 50-100k are planned. There is a functionality that when news or a promotion is released, all clients receive a push notification, and they simultaneously open the application to read the news. But not only the api of one news is twitching, but a couple more requests for the application itself to work, which, in theory, can create a huge load at 1 moment. But in general, the application is not very loaded, and there is no way to allocate a huge server.

I would like to ask how people solve such issues, and what are the passes,

P.s cache options will not help much, since most of the data is personalized

Answer 1

Put in the AWS cloud, Google Cloud or the like. With an autoscaling group. You can scale manually before sending the news.
