Welcome to India Vultr!

Vultr has announced start of their Mumbai location on 12th of this month. It’s amazing to see them entering India. Always a good thing for growth of cloud computing on demand in India.
Besides Vultr, we have got Amazon AWS, Microsoft Azure, Google Cloud, Digital Ocean, Linode, Oracle Cloud etc in India. I heard OVH also planning for Indian location and so have to see how that goes.

In meanwhile, let’s have a quick check on Vultr’s network connectivity. I just created a Virtual machine in Mumbai to look at the routing and connectivity. I got following for my test VM:

NIXI expansion & some thoughts

Background

Lately, NIXI has been making a bit of news in the Indian peering ecosystem. NIXI for those who may not be aware is the National Internet Exchange of India. It was founded in 2003 with the idea to provide inter-connection layer 2 peering fabric for local Indian ISPs. They were supposed to ensure domestic Indian traffic is exchanged within India and not outside of India. In my previous post, I did cover how that is not true for now. They never picked up much interconnection due to a number of fundamental issues with their policies.

Redundancy on the servers without BGP

A developer friend recently asked me about the design of redundancy on servers. He had a valid point - running BGP can be tricky and expensive since most colo & datacenter host would offer simple static routing & usually with just a couple of IP addresses. Furthermore, due to IPv4 exhaustion, the prices of /24 have shot off pretty massively. On top of this burning, a /24 on single or multiple servers is also a questionable design practice unless one of hosting & selling hundreds of virtual machines on those servers.

Updates from life

No blog post since Aug 2021. Last few months extremely (and happily) busy. I got blessed with a baby boy in September and since then being happily busy.

Gotta resume blog posts here!

Glue records is not A record replacement

Someone recently reached out to me discussing DNS and as that person started taking deep dive in DNS, he came across the glue records. He asked me “Why not just use A records on a sub-zone with glue record at the parent zone”?

This was a fantastic question. I am going to document it in this post on why not. First and foremost let’s have a clear understanding of glue records.
