How to setup Amazon Route 53 DNS

Amazon offers many cloud services with their Amazon Web Services brand and Amazon Route 53 is the premium DNS services on AWS. Lots of interesting things can be done with Route 53 other than just hosting your records. Route 53 offers services such as DNS based load balancing, DNS fail over, Health checks etc. Route 53 uses anycast technology to serve records to the users with minimum latency by routing the requests to the nearest server to the user. They have many DNS pop’s (point of presence) on various parts of USA,Europe and Asia so your visitors expect a little bit of a boost in loading speed of your sites. I have been using Linode’s own DNS service for the past 3 years for all of my web sites but since Route 53 is so cheap and promising thanks to anycast, I have decided to use Route 53 DNS for this blog. Here’s how I set it up Continue reading →

Sorry Linode! I have moved out

8 Replies

If you are a regular reader of this blog, you know that I have been a long time advocate of Linode and I have written many reviews about them, here and here. I have been using Linode to host not only this blog but the websites of the company I work for. And it requires stability and uptime because even the billing systems are hosted online. Linode has been great for past 3 years that I have been using them. And lately they have announced their NextGen upgrades . They have doubled the available CPU cores from 4 to 8 and doubled RAM, increased bandwidth and announced the plans to upgrade the host nodes to latest XEON E5-2670 8 core processors. And they have said that they have upgraded disks on the newer host nodes to latest enterprise 15k RPM drives and they aren’t going to use SSD’s anytime soon because of unavailability of professional grade SSD’s for reasonable price.

Yes that’s completely acceptable reason not to switch to SSD’s. But the problem is that disk speed is really low on Linode’s new hosts. I have been getting 60MB/s > speeds from newer hosts every time I test using Continue reading →

How to setup SSH key based access on Google Compute Engine

Leave a reply

If you are a Linux newbie and if you are used to Amazon EC2 or any other VPS control panels, Google Compute Engine terminal system will be confusing for you. Google Compute Engine uses Google’s own tool called gcutil tool to manage Compute Engine and its resources. Not only using it but configuring it is bit hard for the newbies. And you wont ever need that if you are just running one or few VMs and not going to unleash the total abilities of Compute Engine.

There is no way to set a root password’s on VM’s from the Console like you do on control panels like SolusVM but you can use SSH keys to access the terminal without ever touching gcutils. Here’s how to do it, Continue reading →

OpenVPN Auto installer

Leave a reply

Auto installers are designed to make your life easy. Installing and configuring things like Nginx and OpenVPN can be hard for novices. You can use the Nginx Autoinstaller listed on my blog if you need that, but what about OpenVPN? OpenVPN-AS is free and comes with a great web based control panel, but the problem is that the free version is limited to 2 concurrent users. But that’s the way to go if you are fine with 2 user limit, You can view my OpenVPN-AS setup guide here.

If you don’t like the 2 user limit on OpenVPN-AS you can install regular OpenVPN but it requires little bit of work, it has no limits on users and you and your friends or clients can use the same VPN concurrently. I have found a great OpenVPN auto install script on github and I thought about sharing it with you. You can find it here installing it is very easy. See below Continue reading →

Free Windows Server 2012 VPS

Leave a reply

Need to try out WIndows 2012 Server edition? Windows Azure, which is the cloud platform of Microsoft ( like Amazon AWS ) offers you free 90 days of trial for people who want to try out their service. This is just like Amazon AWS free trial but Microsoft is very generous except for bandwidth usage, because they enable you to create VM’s up to 14GB RAM and 8 cores with this free trial. Like I said only downside is that you will get only 20GB of outbound bandwidth and inbound is free.

You can signup here but you will need to provide credit card details to verify your account. But don’t worry, Microsoft is placing $0.01 spending limit for trial accounts so you won’t get charged for anything like if you choose the wrong option. Continue reading →
