Cloud Computing Market Leaders 2015

Cloud Computing Market Leaders, 2015

DatamationWhen Gartner speaks, the cloud computing market listens. In the fractured, still immature cloud market, the research firm's annual Magic Quadrant for Cloud Infrastructure is widely considered the authoritative report on trends and vendor ranking.  The moment it's released, vendors trumpet it or spin it, and pundits tweet and pontificate about it voluminously. One of the report's three authors, Lydia Leong, is arguably the cloud's leading authority.
The report is a hefty tome whose complexity reflects the cloud market's many technologies, with a handful of vendors combining/developing a variety of emerging technologies. Amid the report's dense verbiage, here's a summary of the two market giants that are most shaping the market.

Amazon Web Services: The Undisputed Leader.

The level of dominance Amazon Web Services (AWS) has in the cloud market can hardly be overstated (see the graphic below). While Microsoft holds a respectable number two position, the cloud market can be summed as "there's Amazon, and then there's everyone else." Most of the other vendors could disappear and the vast bulk of the cloud market would remain. It's remarkable but it's true: a web-based business that got its start as a lowly bookseller has clearly bested the most powerful legacy IT vendors in the generational shift of our lifetime.
The report is clear about AWS's strengths: "AWS has a diverse customer base and the broadest range of use cases, including enterprise and mission-critical applications. It is the overwhelming market share leader, with over 10 times more cloud IaaS compute capacity in use than the aggregate total of the other 14 providers in this Magic Quadrant."

High Praise for AWS

The praise gets even higher: "AWS is a thought leader; it is extraordinarily innovative, exceptionally agile, and very responsive to the market."
Gartner does issues a few cautions. It indicates that AWS can be a "complex vendor to manage," and it points out that AWS is "spreading its efforts very broadly." (Which long term, of course, is likely a powerful positive in the race to offer the greatest depth of functionality.)
The report breaks down cloud customers, roughly, into Mode 1 and Mode 2. Mode 1 is traditional IT: legacy workhorse apps and compute resources of established businesses; these customers aren’t early adopters. Mode 2 is the many forms of the cutting edge: developers, start-ups, the mobile app world, speculative tech ventures.
Gartner identifies AWS as primarily appealing to Mode 2 buyers – certainly the developer/start-up crowd was AWS's big head start over the least several years. But Gartner also notes that AWS is "now commonly chosen for Mode 1 needs as well." It's this ability to play in both worlds that is AWS's greatest strength.

Microsoft: Coming on Strong

Microsoft's cloud offering, Azure, initially launched as a PaaS platform, adding IaaS functionality in 2013. Since the Gartner report ranks the IaaS market only, the fact that Microsoft holds the number two spot after a relatively late start reflects the software giant's deep investment in cloud.
As Gartner states, "Microsoft's brand, existing customer relationships, history of running global-class consumer Internet properties, deep investments in engineering, and aggressive roadmap have enabled it rapidly to attain the status of strategic cloud IaaS provider."

If Not for AWS, Microsoft Would Dominate the Cloud

Azure has more than twice as much cloud IaaS capacity as all the other vendors running behind it; if not for AWS, Microsoft would dominate the cloud. This, by itself, is as remarkable as AWS's early lead. Think of it: Microsoft, launched in 1975, and having stumbled in the critical area of mobile, has found solid, dominant footing in today’s forward-looking technology. Very few tech companies can boast of that level of generational refresh. 
Perhaps its greatest strength: Azure "appeals to both Mode 1 and Mode 2 customers," Gartner states. Certainly Microsoft has enterprise in its DNA, so of course it will be strong with its legacy customers, the Mode 1 crowd. Indeed, the report notes that Azure has been a way for Microsoft to leverage its existing client relationships. Long time customers "value the ability to use Azure to extend their infrastructure-oriented Microsoft relationship and investment in Microsoft technologies." And the Mode 2 developer crowd likes Azure’s integration with Microsoft’s app development tools and related technologies.

Price Competition is Tough

Gartner notes that "Microsoft Azure encompasses integrated IaaS and PaaS components that operate and feel like a unified whole." This is a deep strength as PaaS technology continues to gain adherents.
Also key: Microsoft's deep pockets allow it to keep up with AWS's (and Google's) aggressive price cutting, the so-called "race to the bottom" that's taking place in cloud computing. This price competition is a two-edged sword: not only does cloud require gargantuan resources to be a vendor, the price competition is notoriously tough. The IaaS cloud market is no place for little players. Notes Gartner: "Microsoft has pledged to maintain AWS-comparable pricing for the general public, and, on a practical level, customers with Microsoft Enterprise License Agreement discounts obtain a price/performance ratio that is comparable to AWS."
The report offers some cautions about Azure. While Microsoft has met its promised timeframes for introducing critical features, "It has not finished introducing all such functionality." Additionally, "Customers who intend to adopt Azure strategically and migrate applications over a period of one year or more (finishing in 2016 or later) can begin to deploy some workloads now, but those with a broad range of immediate enterprise needs may encounter challenges."
Gartner's toughest criticism of Azure: Some customers have expressed concern about Azure outages, "which may necessitate ensuring that critical applications on Azure have a non-Azure disaster recovery solution."
In sum, the race to capture market share will grow ever more fierce in the years ahead. Here is Gartner's IaaS Magic Quadrant view of the current cloud scene:

Magic Quadrant for Cloud Infrastructure

Cloud: Open Stack Brings Liberty to the Cloud

OpenStack Brings Liberty to the Cloud


When it comes to the public cloud, Amazon Web Services (AWS) is the clear winner today. Outside of the public cloud, the winner on the private side is also clear and it's the open-sourceOpenStack cloud platform.
Simply put, no other cloud technology platform is as widely supported or deployed as OpenStack. OpenStack got its start in 2010 as a joint effort of NASA and Rackspace and in the last five years has grown well beyond its origins. The biggest names in technology now all support OpenStack. HP, IBM, Intel, Cisco, Dell, EMC, VMware, Symantec, Huawei and Yahoo are among its members.
OpenStack
OpenStack: The Open Source Cloud Operating System

Who is Using OpenStack?

Supporting vendors are only half the equation, as production deployments for OpenStack are also impressive. At the OpenStack Summit in Vancouver, which ran from May 18 to May 22, the world's largest retailer, Walmart, described how it is using OpenStack in production to power its ecommerce operations. OpenStack is also the engine behind eBay, Paypal, Comcast, Time Warner Cable and Best Buy. NASA is also still a huge believer in OpenStack and is using it to help build technologies that one day will land humans on Mars.
So now that we understand who is using OpenStack and where, it's important to understand what OpenStack actually is. First of all, despite what you may have read elsewhere, OpenStack is not a homogeneous cloud product. OpenStack is not a virtualization hypervisor product. Actually, to be fair, OpenStack itself isn't even a product at all.
OpenStack, in the words of OpenStack Foundation Chief Operating Officer Mark Collier, is an integration platform. That is, OpenStack provides a framework for cloud services, with a set ofAPIs and tools, into which products and technologies can be integrated and deployed to create an OpenStack cloud.

Vendors Skew The meaning of Cloud

Going back half a step, it's also important to actually define what the word "cloud" means. Different vendors have skewed the meaning of cloud over time to fit their own purposes, though there is a formal NIST (National Institute of Science and Technology) definition that unfortunately is rarely adhered to.
In the context of an OpenStack cloud, let's use a definition of cloud put forward by Amandeep Singh Juneja, senior director of Cloud Engineering and Operations at Walmart Labs.
"At the end of the day, cloud offers the promise that infrastructure is available rapidly and it's flexible," Singh said.
Makes sense to me and that's what OpenStack provides, a framework for infrastructure that can be rapidly deployed and is flexible.

Defining an OpenStack Cloud

Initially, OpenStack started with two projects - the Nova Compute Project and Swift Storage. Inside of Nova, a cloud operator can now choose to deploy from multiple forms of hypervisors and virtualization technologies. VMware's ESX, the open-source KVM and Xen hypervisors and even Microsoft's Hyper-V are all supported and can be deployed in Nova.
Over time, OpenStack has expanded to include multiple projects under the umbrella of what became known as the OpenStack Integrated Release. For the OpenStack Kilo release, whichdebuted on April 30, the integrated projects included: Nova compute, Swift object storage, Cinder block storage, Keystone identity, Horizon dashboard, Glance image, Neutron networking, Trove database, Sahara Big Data, Heat orchestration, Ceilometer monitoring and Ironic Bare Metal projects.
The challenge with the integrated release is that not all OpenStack cloud deployments were actually deploying a full integrated release. Starting with the upcoming OpenStack Liberty release which will debut in October, there is a new model for defining OpenStack. There are DefCore projects, that is items that must be in a cloud for it to be considered to be OpenStack, and then there is a 'Big Tent' full of myriad projects that a cloud operator or vendor can choose to include.
The Big Tent redefines what an OpenStack cloud is all about and can include. It means that the OpenStack Liberty release and those clouds based on it may look different and have different capabilities. That said, DefCore means that certain items need to be present, notably the Keystone Identity service and its APIs. That's important because Keystone enables federated identity across OpenStack powered clouds. It's an idea that the OpenStack Foundation now refers to as the OpenStack Powered Planet. It's literally about OpenStack deployments around Earth that can now all be federated into one massive pool of flexible rapidly deployable computing power.
It is somewhat ironic that an effort co-founded by NASA, whose mission is to expand the reach of humans beyond planet Earth, has now evolved to become an effort that binds the computing power of the Earth together.
OpenStack is now truly set to bring Liberty to the cloud.
