Integration is just one of the challenges. A sophisticated network configuration is needed to transfer data between the private and public clouds that comprise the hybrid environment. Not only must the network transfer the data securely, but it must deliver a seamless user experience. In addition to a fast and reliable network, failover capabilities are needed to handle any system or network outages.

While Microservices and Container Orchestration remains the most prevalent customer initiative to adopt Mesosphere technologies, distributed stateful services together with modern analytics and AI/ML frameworks is a big reason why our customers are DC/OS first.

Above you see a small set of use cases directly shared by our CAB members. Our CAB members partnered with Mesosphere to run DC/OS for many of the above use-cases, such as microservices and data services. This partnership enables them to disrupt their respective industries and drive innovation at the rate of leading hyper-scale companies.

The Cloud Computing is one of the fastest growing technology that attracts researchers to add and improve its services [1][7]. Organizations benefit from this technology by replacing traditional IT hardware and data centers with remote, on-demand paid hardware and software services, that are configured for their particular needs, managed and hosted by the organization users or even a third party. This increases the organization’s flexibility and efficiency, without the need to have a dedicated IT staff or owning special hardware equipment or software licenses.

Much like a giant office building provides the basic resources that can be tailored to fit several different businesses specific needs, Cloud providers offer customizable IT resources to satisfy an organization’s demands. (Salesforce, 2011) Employing Cloud allows the organization to focus on its primary goals and objectives.

Hybrid cloud computing refers to policy-based and coordinated service provisioning, use and management (orchestration) across a mixture of private and public cloud services. Gartner has predicted that by 2019, more than 30 percent of the 100 largest vendors’ new software investments will have shifted from cloud-first to cloud-only. They have also predicted that 90% of organizations will adopt hybrid infrastructure management by 2020. Developing a solid hybrid cloud strategy can help address issues including:

Automation – should support SDN for automated per minute consumption of capacity and automated failover to alternative paths.

Every few years the ever-changing business climate requires technology to transform to meet new market demands. One such change is creating a converged private cloud infrastructure, a culmination of several IT infrastructure trends, all of which provide value for today’s enterprise data center.

VNF as a Service (VNFaaS): Many Enterprises have an infrastructure network of their own. Such a network puts added expenditure on enterprises to have a dedicated team of professionals to maintain and service this network. Also having equipment on their premises increases capital costs and operational costs such as energy. The ISG use cases [10] proposes to provide these enterprise infrastructure equipment as a virtual service hosted at the operator end. From the enterprise perspective it will be profitable for them to outsource this functionality and have

Infrastructure as a Service - IaaS describes a services for provisioning virtualized operating system instances, storage, and network capacity under contract from a

The System administrators can build a local cloud and get capabilities to provide computational, networking and storage resources on demand with the help of API services. With the presence of these API 's, system administrators get huge benefit as compared to vintage manual approaches. Now, the

“IT infrastructure and services delivered over the cloud will be ubiquitous within five years, and vendors that ignore the shift from on-premises software to Internet-delivered technology will be left in the dust. If you are not thinking about and acting on delivering your own offerings through the cloud [within five years], you won 't be in

New imperatives and technologies are forcing companies to rethink their fundamental business assumptions. The C-suite is under pressure to perform at increasingly high speeds and scale - there’s no letting up. Today’s executives are turning to cloud-based solutions to help improve business efficiencies while reducing CAPEX. Executives are immersed in terms like software as a service, open source, big data, cloud, scale-out, containers, microservices etc. While these terms and technologies represent a new world of opportunity, they also bring complexity that most IT departments are ill-equipped to pursue. This has become the Big Software era.

Provisioning of systems and the needed storage can be done from a centralized infrastructure on

Hybrid clouds are considered a combination of public and private clouds. Companies can use third-party cloud providers either fully or partially to increase scalability and reduce equipment costs. Hybrid clouds are often used during peak times to handle workload surges which can reduce the cost since they are only being used when necessary. (Kleyman, 2013). Scenario: a company chooses to use a hybrid cloud to manage occasions where use exceeds capabilities instead of purchasing additional equipment to keep on hand for standby.
