Implementing a Private Cloud Solution

Last week I attended Learning Tree’s “Implementing a Private Cloud Solution” course at our Reston Education Center. It is a great course for anyone seeking in-depth technical details on how to build their own on-premises private cloud. The course also covers using a hosted private cloud solution and building secure connections to your own data center.

This course is not for the faint of heart! It is also not for the technically challenged! When you show up Tuesday morning you need to be prepared to work very hard for the next four days. The course author, Boleslav Sykora, has put together a fast paced session that gives you as much technical detail as you would ever want on the subject. It is the type of course where you will want to come early and stay late each and every day so you can work through all the extensive bonus exercises that are offered. I loved it and I think you will too!

We feature building two private clouds, one using Eucalyptus and another using Microsoft System Center, completely from scratch. There is a lot of Linux command line stuff and quite a bit of detailed networking configuration. This is exactly the reality of what is involved if you want to build your own private cloud. Over the four days you come to understand that private cloud computing is not some mystical, magical hype but is an evolution of solid fundamental concepts that have been around for some time. This course will appeal to technical professionals who want to gain real experience implementing solutions that will define the future of the on-premises data center.

For those who would prefer not to bother with the complexity of an internal private cloud implementation there are many hosted solutions to choose from. Probably the best known is Amazon’s Virtual Private Cloud (VPC). Once you use VPC on Amazon you will likely never go back to using EC2 without it.

In fact as I write this blog I am on a train heading to New York. There I will teach Learning Tree’s “Cloud Computing with Amazon Web Services” course. That, also, is a great course!

Because there are many private cloud implementations based on the Amazon EC2 model and API (particularly Eucalyptus) Amazon has kind of become the de facto standard for how Infrastructure as a Service (IaaS) is done. Even if you believe you would never use a public cloud for a production system there is much to be learned about cloud computing from Amazon. Beyond that the public cloud is a great place to do testing, development and proof-of-concept before investing the time and capital required to build your own private cloud. Public clouds such as Amazon can also become part of a hybrid solution that features the best of what private clouds and public clouds have to offer. Learning Tree’s Amazon Web Services course gives you hands-on experience with many aspects of Amazon’s cloud and shows you how to build solutions using the various services offered there.

So if you are a hardcore techie who wants to have end-to-end control over all aspects of a cloud solution come to Learning Tree’s private cloud course. If you would like to understand how to leverage the Amazon public cloud or to understand the service models of arguably the most dominant cloud provider in the world then come to Learning Tree’s Amazon Web Services course. Either way I hope to see you soon!

Improved Amazon Private Cloud Security: EC2 Dedicated Instances

Back in October last year I posted an article titled ‘How Dedicated is Your Private Cloud ?‘. The main theme was that whilst organisations like Amazon offer private clouds on Amazon infrastructure, your virtual machines may actually be co-hosted on the same physical hardware as other organisations virtual machines. What is private in such scenarios is the virtual network your instances are connected to.

Without a good understanding of cloud computing and the underlying technologies that make this possible, private cloud means one thing, yet to those with a good understanding of cloud computing will know that there are different levels of ‘private’ cloud when that cloud is hosted by a third party. Amazon, as part of their AWS have offered a virtual private cloud (VPC) for some time now. With the Amazon VPC, instances are co-hosted with instances from other organisations. Until today that is. Today, Amazon have announced EC2 dedicated instances which ensure that all EC2 compute instances will be isolated at the hardware level. It is possible to create a VPC in EC2 that has a mixture of dedicated and non-dedicated machine instances all on the same network based on application requirements.

In addition, earlier this month Amazon made some changes to the way VPC’s can be accessed. Originally, the only way of accessing an Amazon VPC was from an IPSec Virtual Private network (VPN). This required extra onsite resources for many organisations. The VPN restriction has now been relaxed and and Amazon VPC can now be accessed by the Internet. Amazon are certainly making the private cloud something that is now comfortably within reach of all organisations.

For anybody who would like to gain an understanding of what cloud computing is, the underlying technologies and how it can benefit their organisation, Learning Tree have developed a Cloud Computing course that provides hands-on exposure to a variety of cloud computing tools and services. In addition, currently under development is a course dedicated specifically to Amazon AWS. If you are interested, more details are provided here.
