Well, maybe everybody is saying “cloud” these days, but my first impression of Microsoft Windows Server 8 (not the final name) is that Microsoft has been listening very closely to what customers want from an OS that can support both public and private enterprise cloud implementations. And most importantly, the things that they have built into WS8 for “clouds” also look like they make life easier for plain old enterprise IT.
Microsoft appears to have focused its efforts on several key themes, all of which benefit legacy IT architectures as well as emerging clouds:
Management, migration and recovery of VMs in a multi-system domain – Major improvements in Hyper-V and management capabilities mean that I&O groups can easily build multi-system clusters of WS8 servers, and easily migrate VMs across system boundaries. Muplitle systems can be clustered with Fibre Channel, making it easier to implement high-performance clusters.
Multi-tenancy – A host of features, primarily around management and role-based delegation that make it easier and more secure to implement multi-tenant VM clouds.
Recovery and resiliency – Microsoft claims that they can failover VMs from one machine to another in 25 seconds, a very impressive number indeed. While vendor performance claims are always like EPA mileage – you are guaranteed never to exceed this number – this is an impressive claim and a major capability, with major implications for HA architecture in any data center.
Recent Forrester inquiries from enterprise infrastructure and operations (I&O) professionals show that there's still significant confusion between infrastructure-as-a-service (IaaS) private clouds and server virtualization environments. As a result, there are a lot of misperceptions about what it takes to get your private cloud investments right and drive adoption by your developers. The answers may surprise you; they may even be the opposite of what you're thinking.
From speaking with Forrester clients who have deployed successful private clouds, we've found that your cloud should be smaller than you think, priced cheaper than the ROI math would justify and actively marketed internally - no, private clouds are not a Field of Dreams. Our latest report, "Q&A: How to Get Private Cloud Right," details this unconventional thinking, and you may find that internal clouds are much easier than you think.
First and foremost, if you think the way you operate your server virtualization environment today is good enough to call a cloud, you are probably lying to yourself. Per the Forrester definition of cloud computing, your internal cloud must be:
Highly standardized - meaning that the key operational procedures of your internal IaaS environment (provisioning, placement, patching, migration, parking and destroying) should all be documented and conducted the same way every time.
Highly automated - and to make sure the above standardized procedures are done the same time every time, you need to take these tasks out of human error and hand them over to automation software.
Having attended the OpenStack Design Summit this week and at the same time fielding calls from Forrester clients affected by the Amazon Web Services (AWS) outage, an interesting contrast in approaches bore out. You could boil it down to closed versus open but there’s more to this contrast that should be part of your consideration when selecting your Infrastructure as a Service (IaaS) providers.
The obvious comparison is that AWS’ architecture and operational procedures are very much their own and few outside the company know how it works. Not even close partners like RightScale or those behind the open source derivative Eucalyptus know it well enough to do more than deduce what happened based on their experience and what they could observe. OpenStack, on the other hand, is fully open source so if you want to know how it works you can download the code. At the Design Summit here in Santa Clara, Calif. this week, developers and infrastructure & operations professionals had ample opportunity to dig into the design and suggest and submit changes right there. And there were plenty of conversations this week about how CloudFiles and other storage services worked and how to ensure an AWS Elastic Block Store (EBS) mirror storm could be avoided.
On September 15th between 11am-12pm EDT Forrester held an interactive TweetJam on the future of cloud computing including Forrester analysts Jennifer Belissent, Mike Cansfield, Pascal Matzke, Stefan Ried, Peter O’Neill , myself and many other experts and interested participants. Using the hashtag #cloudjam (use this tag to search for the results in Twitter), we asked a variety of questions.
We had a great turnout, with more than 400 tweets (at last count) from over 40 unique Tweeter’s. A high level overview of the key words and topics that were mentioned during the TweetJam is visualized in the attached graphic using the ManyEyes data visualization tool.
Below you will find a short summary of some key takeaways and quotes from the TweetJam:
1. What really is cloud computing? Let’s get rid of 'cloud washing!'
Have questions about cloud computing and the top challenges and opportunities it presents to vendors and users? Then join us for an interactive Tweet Jam on Twitter about the future of cloud computing on Wednesday, September 15th, 2010 from 11:00 a.m. – 12:00 p.m. EDT (17:00 – 18:00 CEST) using the Twitter hashtag #cloudjam. Joining me (@hkisker) will be my analyst colleagues Mike Cansfield (@mikecansfield), Pascal Matzke (@pascalmatzke), Thomas Mendel (@drthomasmendel), and Stefan Ried (@stefanried). We’ll share the results of our recent research on the long term future of cloud computing and discuss how it will change the way tech vendors engage with customers.
Looking through the current industry hype around the cloud, Forrester believes cloud computing is a sustainable, long-term IT paradigm. Underpinned by both technology and economic disruptions, we think the cloud will fundamentally change the way technology providers engage with business customers and individual users. However, many customers are suffering from "cloud confusion" as vendors' marketing stretches cloud across a wide variety of capabilities.
To help, we recently developed a new taxonomy of the cloud computing markets (see graphic) to give vendors and customers clear definitions and labels for cloud capabilities. With this segmentation in hand, cloud vendors and users can better discuss the challenges and benefits of cloud computing today and in the future.
The rise and rise of cloud has been dominating the headlines for the past few years, and for CIOs, it has become a more serious priority only recently. People like cloud computing. Well - at least they like the concept of cloud computing. It is fast to implement, affordable, and scales to business requirements easily. On closer inspection, cloud poses many challenges for organizations. For CIOs there are the considerable challenges around how you restructure your IT department and IT services to cope with the new demands that cloud computing will place on your business - and often these demands come from the business, as they start to get the idea that they can get so many more business cases over the line for new capabilities, products and/or services, as they realize that cloud computing lowers the costs and hastens the time to value.
