Amazon and Eucalyptus Partnership: A Boost for Hybrid Cloud Development

I was extremely pleased to hear that Amazon and Eucalyptus have partnered to provide formal support of their common API’s. I am certain I will not be the only one who finds this news exciting. Anyone who has attended Learning Tree’s Introduction to Cloud Computing course will have gained hands-on experience of working with a Eucalyptus private cloud. They will have learned the capabilities of this cloud and that Eucalyptus have an API that is compatible with Amazon AWS. This formal support agreement will enable the expansion of the API as well as the formality of the partnership bringing great credibility to the Eucalyptus cloud software.

Many organisations make use – or could make significant use – of on-premise (private) clouds as well as public clouds. Doing so often requires different toolsets and technical skills for efficient working. This partnership will now enable a uniform toolset and skill set to be used to access both the private and public clouds. Because of the wide range of services Amazon AWS provides, a wide range of infrastructure configurations could be rapidly self-provisioned including on-premise Eucalyptus and Amazon private cloud, on-premise Eucalyptus and Amazon public cloud or a mixture of on-premise Eucalyptus and Amazon public and private clouds.

Why would a mixture of on-premise Eucalyptus and Amazon cloud services be required ? There are many reasons for this. For instance, for periods of peak demand, where the on-premise infrastructure may not be sufficient, Amazon could be used to provide the extra required capacity. Another may be that services not provided by Eucalyptus are required but are available on Amazon and so Amazon is used. Some services may be better deployed to an Amazon cloud than on-premise – for security reasons. There are many, many reasons why a hybrid solution may be the preferred solution. What is clear is that this partnership, will, in my opinion, make the decisions easier to make because of the transparent switch from one to the other based on the common API’s and toolsets.

For anybody interested in learning more about Cloud Computing, the different types of cloud configurations, the way they can integrate – or not – consider attending Learning Tree’s Introduction to Cloud Computing course. Here you will gain an exposure to a wide variety of cloud computing products and services and importantly their strengths and weaknesses – all from a vendor neutral view. For Amazon AWS you will get a coverage of the services provided and also for Eucalyptus together with experience of using the toolsets to provision resources from these clouds.

Hybrid Clouds: A Flexible Solution to Challenging Requirements

In my consulting and teaching activities related to Cloud Computing, private clouds are one of the most popular topics I am asked about. Recently, when visiting a client that has a large IT infrastructure (greater than 100K devices), in a business that is highly regulated, they were extremely keen to find better ways of working with this large infrastructure. I met with both business and technical personnel and both groups expressed a high level of dissatisfaction with the current traditional approach to managing IT. They were aware that Cloud Computing potentially offers them a solution that could significantly improve both the business and technical aspects of managing their IT, but were unclear on how – hence my visit.

Given their highly regulated environment, my client had discounted using a public cloud provider such as Amazon or Microsoft, but was willing to consider a private cloud deployment. This was interesting as they had no knowledge or experience of working with private clouds but thought they would be more secure. Once we began examining their requirements in more detail, it quickly became clear that some of their IT needs could be met by using a public cloud provider such as Amazon. The reason I use Amazon as an example is because they publish their security policies and accreditations in a very clear way. What also became evident as our analysis progressed is that some of this organisations IT had to remain on premise under their control. To more efficiently manage the on-premise infrastructure a private cloud is definitely a suitable solution. As a total solution, a hybrid cloud, with highly sensitive resources secured on a private cloud that is linked to a public cloud for less sensitive resources – albeit still in a secure environment is the safest, cost effective way forward.

As Cloud Computing becomes established, it is my firm belief that hybrid clouds will become the norm as organisations manage on premise IT with private clouds and use public clouds for a variety of reasons, to augment the on-premise IT, including providing overspill capacity, to testing, training, research and development.
