@educator Hi there. Fellow Indian here. I would recommend DigitalOcean over Vultr due to a number of reasons having used both. However there is a 3rd option which is better imo and that is Linode. 2 main reasons. Linode offers double RAM at 10$. You get 2gb RAM instead of 1gb for 10$. What I am getting from your post is that you want a 5$ plan. However it will be insufficient for even a small sized forum. Try going for the 2gb RAM option at Linode. Unless you are a registered business in India you shall have to pay 15% service tax on Digitalocean as of Jan 1 2016. Businesses dont have to pay this tax as long as they dont have a turnover of greater than 10 lacs per annum. This is because DO has officially entered the Indian Market and will need to comply with the Indian Tax authorities. This is not the case of Linode as they dont have an Indian office . This means that the DO plan at 10$ will be more than twice expensive when compared to Linode. Rest is upto you. Feel free to ask anymore questions

@jarey The amount of good replies I get in this nodebb is great. Thank you. So, I am going with nodebb. Having a positive energy that people will help us in the long run

LXC refers to the technology that enables programs to work in containers like Docker. I haven't tried it, but there are dockerized versions of NodeBB that are supposed to be easy to deploy. Because it's still kind of a new technology for deployment YMMV. Traditionally NodeBB is deployed as a process running on a VPS (which is commonly a VM dedicated to you (aka KVM)) since it already has all the daemonization logic built in. So, this is the best tested and most common method of deployment. You can get a VPS from providers like Digital Ocean, AWS, Azure, etc. Even if you don't have access to educator resources, there are typically ways to get free server time
