Part 3: How I Built a cPanel Hosting Environment on Amazon AWS

In Part 2 of this series, we discussed selecting and launching a new Amazon Machine Instance (AMI), creating and configuring that instance to serve as a dedicated name server, and worked through configuring a DNS Cluster for use within your subnet.

Today, we will launch and configure a standard Web Server instance using cPanel 11.39 or newer. I will discuss how to join the new instance to our existing DNS Cluster and how to ensure that 1:1 NAT is configured and working properly.

The Scrum Method, via Chad McCanna

Here at cPanel, we use the Scrum framework to ensure an organized flow for each project. Recently, Chris, a Technical Product Specialist, asked Chad McCanna, our Scrum Master rockstar, to share some insight about why this works so well for cPanel.

“Chad, in your words, what is a Scrum Master?”

A Scrum Master is classified as a servant leader. They’re basically in charge of facilitating the development process and owning the Scrum framework. They act as a barrier between the product owner, stakeholders, and the team itself. They need to be the conduit through which all information passes, or at least be present during all conversations so that there’s no violation. For example, if you have someone’s manager acting as a product owner, there can be some influence there. The Scrum Master is there to kind of diffuse that, to allow the team to focus on their commitments; so yeah, they wear a lot of hats. In a nutshell, the Scrum Master owns the process and ensures that everyone else is able to do their jobs to the best of their ability.

“When you say “do their jobs to the best of their ability”, and then you state that you’re a facilitator of the development process, can you elaborate?”

IPv6: Update

Greetings again, I am Phil King, the Product Owner of the Angry Llama Scrum team, which is actively working on IPv6.

Here is a link to a brief demo of the IPv6 features we have completed to date. Our focus thus far has been on enabling IPv6 on website content.

Our IPv6 work is currently targeted for cPanel WHM version 11.40.

Currently, we are working on tools to better handle multiple IPv6 ranges or subnets. This will enable the customers that want to break up a large allocation (e.g., a /64) into smaller ranges, and also assists the customer that gets only a handful of IPv6 addresses.

Part 2: How I Built a cPanel Hosting Environment on Amazon AWS

In Part 1 of this four part series, we discussed establishing your VPC, creating and configuring your small subnet, and worked through configuring the Security Groups for our two instance types (‘NS_SG‘ and ‘VS_SG‘).

Today, we work on launching a two new instances, running cPanel DNSONLY, into our VPC and configuring these to be the primary and secondary DNS resolvers for our environment. While this series is written with the assumption of using dedicated DNS instances, you could easily use these instructions on dual use instances that both serve as web servers and as name servers.

Part 1: How I Built a cPanel Hosting Environment on Amazon AWS

People argue for and against building a production hosting environment on top of cloud services such as Amazon’s AWS. I recently made the decision to migrate my entire hosting infrastructure from co-located dedicated hardware to a full implementation built entirely on top of Amazon’s Web Services.

I will be releasing a four part series detailing the tricks I’ve learned in my own migration to AWS and walking you through setting up your own full service hosting environment within the AWS eco-system, all while still leveraging the power of cPanel, WHM, and DNSONLY.

I chose to use AWS, more specifically EC2, VPC and S3, for its rapid deployment, unlimited scaling, load balancing, and global distribution abilities. Working with AWS, I started to realize just how powerful it could become.

I started this challenge with a few key questions: What are the benefits and the challenges one would face working in an environment like this? All of our servers run instances of cPanel/WHM, so what are the difficulties in setting up cPanel in an AWS environment?

Amazon’s AWS platform is built behind a NAT infrastructure, so inherently, configuring cPanel for a NAT used to be an elaborate ballet of duct taped scripts and hooks. However, with cPanel 11.39, I’ve been able to seamlessly migrate my entire infrastructure ( 30+ instances ) from a dedicated environment to AWS without any misstep.

The result is a solid hosting architecture using Amazon VPC (Virtual Private Cloud), Amazon EC2 (Elastic Cloud Compute) and Amazon S3 (Simple Storage Service), built with cPanel/WHM/DNSONLY that not only works on AWS, but makes deployment and provisioning of new servers unbelievably rapid and simple.

We’ll Meet You at Booth #323

It’s all fun and games until you leave the cPanel booth at HostingCon! Unless it’s for a session, then we’ll let it slide.

We’ll be showing upcoming features in the next release, like IPv6. You really have no idea how excited I am to share that! Phil King, the leader of that project, will be on hand in the booth to answer your IPv6 questions, along with some of our other brilliant cPanel staff. IPv6 will be in good company with demos highlighting the changes in our user interface with X4, along with 1:1NAT.

Not only are we exhibiting, some of cPanel’s own will be holding sessions.
On Tuesday, June 18th:

Dan Muey will be taking part in the Lightning Talks as a moderator at 9 AM in room #16.

Eric Ellis, our Director of Development Operations, will be leading a panel with our head system administrators at 10 AM in room #18D:
‘Operation Hack You: Security Panel from Real Systems Admins’
Security is a complex field, changing every day. Who better to tell you about the threats you face and the best methods of defense than four system admins who spend their time fighting against attackers? In this down-to-earth panel designed for others on the front-line, Adam, JD, Scott, and Cory will share some real-world scenarios that result in security breaches. You’ll understand how a hacker would get into your network, charge up your credit card, and steal your identity – and what you can do to stop this from happening.

On Wednesday, June 19th:

Our Director of Product Development, Ken Power, will take part in a session about IPv6 at 9 AM.
‘Now is the Time for IPv6′
The Internet is facing imminent IPv4 depletion, which will impact all hosting service providers. To continue business growth and prepare for the future, a move toward Internet Protocol version 6 (IPv6) is essential. In this panel session, we will review the business case for IPv6 adoption and why you should be transitioning to IPv6 now. Our experienced panelists will draw on their experiences in deploying IPv6 to help you understand the necessity of this transition and the obstacles that may appear along the way. You will also hear about best practices for everything from continual management to training your IT staff.

Perl-ing 101 & GIT Training

Forever aspiring to evolve and learn more, some of our team got a chance to intensively learn about Perl over four solid days last April, followed by GIT training and testing in May.

brian d. foy, a longtime Perl devotee and author, came to cPanel and taught a Perl 101 class. While it may come second nature to some of you, that isn’t always the case, so we were thrilled to have one of the best here to teach the class.

The class covered scalars, arrays, lists, subroutines, basic input/output, regular expressions, hashes, control structures, and file handles. Attendees also got to go first in the cPanel lunch line. All around, a win.

Mike Schwern taught the GIT class and definitely knew his audience:

The same Perl course will be taught at the upcoming YAPC::2013 Conference this June 3rd- 5th, in Austin, Texas.
