How to start a project if there is no big finance?

Question

Startups

Good afternoon, let's say there is a ready-made project (node.js, although this is not so important) that works locally.
To launch it into the world, let's say I rent a digitalOcean tariff for $ 10 with 1GBMemory + 1 CoreProcessor + 30GBSSD Disk + 2TBTransfer
For half a month, my startup is gaining momentum and I see that this tariff is not enough for me. Can I, without any loss of data (from the database), switch to a tariff for 160$/month with 16GBMemory+8 CoreProcessor+160GBSSD Disk+ 6TBTransfer ?

Answer 1

raise a new server, set up database replication (so that the database on the old and new servers are synchronized), then transfer DNS to the new server and when they are all updated, put out the old one.
And instead of a node for 160 a month, you can try adding one or two more for $10, set up replication again, and put another node on the front to proxy requests through nginx.
And you can also move the database to a more powerful server and leave a couple of servers for the application ...
It all depends very much on what your bottlenecks are. If there is not enough space due to a large amount of static, you can move the static to a separate server. If the base grows - it is possible to take out base. Well, you understand.

Answer 3
