The Data Center’s Hybrid Cloud Future

Nearly half of large enterprises will have hybrid cloud deployments by the end of 2017. Hybrid cloud computing is at the same place today that private cloud was three years ago; actual deployments are low, but aspirations are high, says Gartner in a published news note from Oct. 2013.

Almost every organization today utilizes some form of cloud computing, usually public clouds.  In its State of the Cloud survey RightScale found 94% of organizations are running applications or experimenting with infrastructure-as-a-service, 87% of organizations are using public cloud, and 74% of enterprises have a hybrid cloud strategy and more than half of those are already using both public and private cloud. RightScale estimates may be a bit more generous than Gartner but both come to the same conclusion in the end: Hybrid cloud is the approach of choice.

Executive management, however, prefers private clouds for the control and security they promise. That the actual control and security may not be much better than what the organization could achieve in the public cloud if it were rolled out properly, but executives don’t understand that. So private clouds are management’s darling for now.

Private clouds, however, fail to deliver the key benefits of cloud computing—cost efficiency and business agility. The organization still has to invest in all the IT resources, capacity, and capabilities of the private cloud. Unlike the public cloud, these are not shared resources. They may repurpose some of their existing IT investment for the private cloud but they invariably will again have to acquire additional IT resources and capacity as before. And, the demand for resources may increase as business units come to like IT-as-a-Service (ITaaS), the rationale for private clouds in the first place.

As for business agility with private clouds—forget it. If new capabilities are required to meet some new business requirement, the organization will have to build or acquire that capability as it did before. The backlogs for developing new capabilities do not magically go away with ITaaS and private clouds. If business agility requires the business to pivot on a moment’s notice to meet new challenges and opportunities there is only one way the private cloud can do it–develop it in-house, the old fashioned way.

Hybrid clouds provide the answer. Gartner, Inc. defines a hybrid cloud as a cloud computing service that is composed of some combination of private, public and community cloud services from different service providers. In the hybrid cloud scenario, the company can rely on its private cloud and happily cruise along until it needs a capability or resource it can’t deliver. Then the company reaches out through the hybrid cloud to the public cloud for the required capability. Rather than build it, the organization basically rents the capability, paying only for what it uses when it uses it. This is ideal when the organization needs to temporarily augment resources, capacity, or capabilities to meet an unanticipated need.

Hybrid clouds, unfortunately, don’t just pop up overnight. First you need to lay the groundwork for your hybrid cloud. That entails identifying the specific cloud resources and services in advance, making the necessary financial arrangements with appropriate public cloud vendors, and establishing and testing the connections. Also, check with your auditors who will want to be assured about security and governance and similar details.

While you are at it, make sure your networking and security teams are on board. Ports will need to be opened; the firewall gods will need to be appeased. You also will need to think about how these new capabilities and services will integrate with the capabilities and services you already have. This isn’t necessarily a major undertaking as IT projects go but will take some time—days or, more likely, a few weeks—to get the approvals, assemble all the pieces, and get them configured and tested and ready to deploy.

As RightScale notes: although the use of cloud is a given, enterprises often have different strategies that involve varying combinations of public, private, and hybrid cloud infrastructure. For most, however, the hybrid cloud provides the best of all cloud worlds, especially in terms of cost and agility. You can run ITaaS from your private cloud and pass through your hybrid cloud whenever you need public cloud resources you don’t have in house.  Just make sure you set it up in advance so it is ready to go whenyou need it.

Mitigate Cloud Risk Through Open Source

The drumbeat of cloud computing has become so loud that no business manager can avoid its siren song of lower cost, greater business agility, and the perfect alignment of business and IT. Although much of cloud computing is based on open source technologies, namely Linux, it hasn’t been viewed as an open source phenomenon.

Cloud computing has proven easier said than done. Even before the recent Amazon cloud disaster when hundreds of Amazon Elastic Cloud Computing (EC2) customers lost access to their applications and data for most of a day or longer, technology vendors had been scrambling to make cloud computing easier to deploy and use.

Red Hat, the large open source Linux provider, is the latest to launch a series of cloud technologies that promise to mitigate the risk of deploying applications to the cloud.   IBM, HP, Microsoft, EMC, Dell and others have their own initiatives aimed at doing the same thing. The Red Hat initiatives, as you’d expect, make extensive use of open source tools and frameworks to simplify the development and deployment of cloud systems and reduce the risk involved.

In some ways cloud computing appears remarkably simple. Just take a SaaS application like Salesforce.com, which is delivered via the cloud. All you need is a browser, deployment can be fast and easy, and the costs are reasonable and predictable.

Things get more complicated, however, when you want to start mixing and matching various cloud services and SaaS applications. Or you want to combine private and public cloud capabilities in a private cloud, creating what amounts to a hybrid cloud, and then build and deploy some of your own applications along with the cloud components. Of course, you’ll want to integrate and manage it all as a single system for efficiency.

Well, that’s not so easy. It can be done but you have to overcome the understandable tendency of vendors to lock you into their particular way of doing things. You end up with a lot of piece parts that don’t necessarily work together, at least not without a lot of cobbling on your part. This is where open source can help.

Earlier this week, Red Hat took a major step in enabling organizations to simplify cloud development and deployment and reduce risk. It introduced a platform-as-a-service (PaaS) offering called OpenShift. It is aimed at open source developers and provides them with a flexible platform for developing cloud applications using a choice of development frameworks for Java, Python, PHP and Ruby, including Spring, Seam, Weld, CDI, Rails, Rack, Symfony, Zend Framework, Twisted, Django and Java EE. It is based on a cloud interoperability standard, Deltacloud, and it promises to end PaaS lock-in, allowing developers to choose not only the languages and frameworks they use but the cloud provider upon which their application will run.

By building on the Deltacloud cloud interoperability standard, OpenShift allows developers to run their applications on any supported Red Hat Certified Public Cloud Provider, eliminating the lock-in associated with first-generation PaaS vendors. In addition it brings the JBoss middleware services to the PaaS experience, such as the MongoDB services and other RHEL services.

At the same conference, Red Hat introduced CloudForms, a product for creating and managing IaaS for private and hybrid clouds. It allows users to create integrated clouds consisting of a variety of computing resources and still be portable across physical, virtual and cloud computing resources.  CloudForms addresses key problems encountered in first-generation cloud products: the cost and complexity of virtual server sprawl, compliance nightmares and security concerns.

One key benefit of CloudForms is the ability to create hybrid clouds using existing computing resources: virtual servers from different vendors, such as Red Hat and VMware; different cloud vendors, such as IBM and Amazon; and conventional in-house or hosted physical server, both racks and blades. This level of choice helps to eliminate lock-in and the need to undergo migration from physical to virtual servers in order to obtain the benefits of cloud.

Other vendors also have introduced new cloud initiatives recently. IBM, for example, demonstrated an enterprise cloud service delivery platform that it is piloting with key clients.  It promises to allow enterprise clients to select key characteristics of a public, private, and hybrid cloud to match to their workload requirements from simple Web infrastructure to complex business processes. These characteristics fall along five risk dimensions: security, performance/availability, technology platform, management/deployment, and payment/billing.

HP has joined with Red Hat in what is being called the Red Hat Cloud-HP Edition.  This is a private cloud design and reference architecture for IAAS and combines Red Hat Cloud solutions with HP’s CloudSystem, Cloud Maps and associated services.

Add to the above what Dell, Microsoft, EMC, and others are doing with initiatives to simplify and streamline business use of the cloud and it becomes clear that the vendors have gotten the message: Businesses want cloud computing that delivers what it promised—open, flexible, reliable, and efficient computing. It will take a few years to build it out, but it just got a big boost.
