Is there anyone who can give me a suggestion for the hosting of my blog. I mean what should I pick either managed cloud hosting or unmanaged cloud hosting. I am looking for AWS cloud hosting and their are companies like Cloudways who are providing the managed AWS cloud hosting. So which one is better.?

For a blog, I guess anyone goes. It will depend on cost. I always advise that you start small, and as you grow, you can use larger resources -- scale up as is required.

If you are just starting, lets say less than 500 visits per day, go for share. I will like to recommend inmotionhosting shared hosting, very expensive though. 

But if you are just starting afresh, pick one of the local Hosting. Move abroad if they ever screw your website. 

Dont forget Regular backup

J+ for goodmuyis, I just did not want to say it earlier, but you see, for a blog that is just starting a share is just better.
