Using AWS services as backend to make an instagram(no videos initially) like app : <p>I am using AWS s3 to store images and ec2(t2.micro free tier) instance to save images url and user details.i have tested it and its working fine.</p>

<p>I want to rent servers and make the app live in play store now.
Im confused which ec2 instance i should go with ?</p>

<p>And will i need Load balancers and more than one ec2 instance for the initial phase of 2000-3000 users(for a month)?</p>

<p>Do i need to add any other service?</p>

<p>I am not an expert at managing servers because i have just learnt and yet to learn other AWS services.I want the servers to run well until the user number grows more than 3k.
Would be glad to get exact answers.</p>
