Hybrid cloud computing combines private and public clouds for flexibility and scalability. It allows organizations to run mission critical applications on a private cloud while using public clouds for development, testing, and peak workloads. However, hybrid clouds increase complexity due to differences in tools, processes, and APIs between private and public clouds. Managed cloud services help address this challenge by outsourcing infrastructure management, freeing internal IT staff to focus on innovation.

In 2010, after IT directors expressed concerns over public cloud security issues, the focus shifted to private clouds. And now, because everyone wants operational flexibility, hybrid clouds are at the top of the wish list.

The arrows indicate the direction of migration. En- terprise users are connected to the clouds using safe connections, which can be virtual private networks (VPNs) or secure HTTP browsers. A hybrid cloud could also theoretically consist of multiple private and/or public clouds. The enterprise data center denoted in the illustration may have active servers (virtualized or physical) that are not included in the private cloud.

Hybrid cloud interest is powered by the desire to take advantage of public and private cloud benefits in a seamless manner. Some of the risks associated with public and private clouds, however, can also be issues in hybrid clouds. The benefits and risks of public, private, and hybrid clouds include: PUBLIC CLOUD BENEFITS: Low investment hurdle: pay for what you use Goodtest/developmentenvironmentforapplicationsthatscaletomany servers PUBLIC CLOUD RISKS: Security concerns: multi-tenancy and transfers over the Internet IT organization may react negatively to loss of control over data center function PRIVATE CLOUD BENEFITS: Fewer security concerns as existing data center security stays in place IT organization retains control over data center

Ideally,theywanttobeabletocreateapplications,ormoveexistingapplications between the clouds in a hybrid cloud environment, without having to change anything serious like networking, security policies, operational processes or management/monitoringtools.Thisisaproblembecause,duetoissuesaround interoperability, mobility and differing APIs, tools, policies and processes, hybrid clouds generally increase complexity. In the second half of this two-part tutorial on hybrid cloud, we take a look at the most prominent hybrid cloud options available on the market and determine the best use case for a hybrid cloud computing offering.

That was the message from Melanie Posey, research vice president for IDC, an analyst firm based in Framingham, Mass., who spoke at a Rackspace- hostedconferenceherethisweek.With80%ofbusinessesusingsomeformof cloud computing resources, Posey paraphrased Winston Churchill in saying thatwe’renotatthebeginningoftheendwithcloudadoption,butattheendof the beginning. “Everybody’s doing it,” Posey said. “We’ve gotten past the point where it’s this new, interesting, exciting thing, and now it’s just a part of doing business.” Organizations will spend $122 billion on public cloud IT services in 2018 and those using cloud expect to increase their cloud spending by 34% over the next two years, according to IDC.

Tech companies often feel that unless they’re doing everything themselves, they’re not a bonafide tech company, but that mindset has to change. “In the digital economy, you’re not selling tech,” Posey said. “You’re selling anapporyou’resellinganexperienceoryou’resellinganewwayofconsuming aproduct.Theinfrastructureistherebecauseithastobe,butaserviceprovider can help you innovate on that infrastructure as well.” Alongwithmobile,socialandbusinessanalytics,cloudisoneofthepillars inthenextwaveofIT,Poseysaid.ItblursthelinesbetweentheITdepartment and the business department and forces businesses to engage in continuous innovation and transformation.

With all the unknowns around how that growth will be realized, having a partner to help that implementation is appealing, he said. “I have no doubt it will cost us more than if we knew everything going into it, but the benefits far outweigh the risks,” Ducey said. There are only a handful of service providers offering managed cloud, in- cluding Rackspace, Datapipe and Carpathia, Inc., but the number of vendors will likely increase to meet demand, Posey said. There will be different types of clouds for different customers, and man- aged cloud will fill an important role going forward, Posey said. It can assist notonlywiththeday-to-dayservicesandinstalldemands,but,asweenterthe mass adoption stage of cloud, there will only be so many cloud experts to hire and retain for companies that want to do it themselves. Do-it-yourself cloud worked great for early adopters, but even some of them that jumped in feet first are starting to move to managed cloud because of troubles with scale and complexity, Posey said. The reason is half of U.S. organizations don’t have enough people in their IT department to effectively support cloud, while another 45% have the people but aren’t necessarily up to date on the latest and greatest, she added.
