Cloud computing, in both public and private mode, has become the new enterprise standard. At the same time, enterprises are continuing to work with managed service providers (MSPs) for a widening range of IT solutions, including cloud support.\nThese two trends are linked. CIO Senior Writer Thor Olavsrud last summer noted that \u201cleaning on an MSP for a subset of your IT services can be a boon.\u201d He also pointed to a CompTIA study indicating that the percentage of MSPs who say that cloud services play no role in their offerings was \u201calmost immeasurably low.\u201d A good case for combining the two is the hybrid cloud. Microsoft Azure Stack, the private cloud environment for Azure initially released in July 2017, is such a case.\nHybrid platform and use cases\nThe promise of a hybrid cloud platform is its ability to bridge the public hyper-scale computing environment with that of the private cloud, whether deployed on-premises or in a third-party data center. It\u2019s like Facebook moving into the enterprise space, a strategy that reportedly is in the works. Only the hybrid cloud is already rolling out.\nMicrosoft began shipping Azure Stack in late September, 2017. (Disclosure: we work for NTT Communications, which launched an application testing and validation lab for Azure Stack at that time.) Another hybrid platform from Amazon Web Services (AWS) and VMWare went live in August; and Google announced a similar partnership with Cisco in October, with plans for a release later in 2018.\nThe hybrid platform tackles inherent challenges of private clouds. They are not only difficult to stand up, as Chief Architect for the Azure Infrastructure and Management Team Jeffrey Snover explains, but they can then become \u201csnowflakes,\u201d unique configurations \u201cdoomed\u201d by a lack of documentation, training, education and community. At a time when enterprises often lack the ability to discover \u2013 let alone manage \u2013 their cloud resources, the consistency of Azure Stack is a welcome development. In his talk at Azure OpenDev in June 2017, Snover points to three promising use cases:\n1. Data sovereignty\nThe European Union\u2019s General Data Protection Regulation (GDPR), scheduled to take effect on May 28, 2018, is today\u2019s poster child for the principle that information is subject to the laws of the country where it is stored. Enterprises doing business in the EU and those handling data of EU residents are finding that GDPR implementation is a \u201ccomplex undertaking,\u201d as these IDC security experts write. Being able to bridge public and private clouds, as with Azure Stack, should reduce that\ncomplexity. In such efforts, enterprises can also benefit from global expertise in network and infrastructure security, data center management and regulatory compliance.\n2. Application development\nAnother case highlighted by Microsoft relates to application development and management. One common use of Azure, or any other public cloud, is as a sandbox. The advantage of Azure Stack is that software engineers need not use different frameworks. They develop once and deploy once. At the same time, Azure Stack simplifies application modernization. Having a common environment makes it easier to grow a new front end and retire legacy code. \u201cAzure stack is all about empowering DevOps teams,\u201d Snover said. Yet along with a hybrid cloud platform, enterprises will need to tap internal or external resources for actually managing these applications and their lifecycles.\n3. Edge and disconnected apps\nA third category involves special applications where Internet connectivity is unavailable, inadequate or undesirable, or where data is simply better suited for batch processing. A cruise ship or off-shore oil drilling rig may be disconnected but still want access to a cloud. A manufacturer or Formula One team may generate tremendous amounts of data, but require intermittent and bursty connectivity. In all such cases, a hybrid cloud platform makes sense. To support the connected cases, enterprises will also need capable service provider partners, preferably with native Azure (or other hybrid platform) integration on the backbone.\nPlatform plus managed services\nOne driver of the hybrid platform is simplification. Microsoft talks about a \u201cdriver\/mechanic\u201d model in which the enterprise pays attention to the dashboard and calls for tech support when a light goes on. That\u2019s a good, but limited analogy.\nA hybrid cloud platform doesn\u2019t arrive ready to drive, but must be architected to an enterprise\u2019s particular circumstances. Likewise, with connectivity, which today is being powered by flexible, software-defined technologies. When implementing the hybrid cloud, to borrow from Olavsrud, enterprises will find it a \u201cboon\u201d to lean on MSPs. Those providers with a strategic cloud focus and a full portfolio of highly secure networks and data centers should be especially good fits.\nThe arrival of the hybrid cloud platform is a welcome development. Already engaged with Microsoft Azure (see our recent DRaaS offering), we are pleased to support Azure Stack. The hybrid cloud category will become all the more successful with the right application of managed services.
