SAP Converged Cloud is a private managed cloud developed and marketed by SAP.[2][3]

It is a set of cloud computing services that offers managed private cloud, based on the OpenStack technology-based public cloud. It is used by SAP's organization for their own internal IT resources to create a mix of different cloud computing environments made up of the Openstack services. It offers compute, storage, and platform services that are accessible to SAP.

History

In 2012, SAP promoted aspects of cloud computing.[4] In October 2012, SAP announced a platform as a service offering called the SAP Cloud Platform[5][6][7] In May 2013, a managed private cloud offering called the S/4HANA Enterprise Cloud service was announced.[8] [9] [10]

SAP Converged Cloud was announced in January 2015. SAP Converged Cloud is managed under a SAP business unit established in 2015 named The Converged Cloud unit, headed by Markus Riedinger as Unit manager. The Converged Cloud BETA went live in May 2017, included OpenStack technology-based storage, compute network components, and shared new services made by SAP:[11] Later, Designate (DNS as a Service) was added as well. On June 7, 2017, SAP announced that the company plans to invest over $1 billion in cloud over the next two years.[12]

Cloud computing challenges

Moving between clouds

Business organizations that want to use cloud computing have a choice of using a private cloud, which is a cloud infrastructure run specifically for a single organization that it built itself or by a third-party; or a public cloud, whereby a service provider makes available applications, storage, and other resources to the general public.[13] The decision of which to use is based on a number of factors, such as whether the company operates in a highly regulated sector, such as the pharmaceuticals industry that must comply with rules regarding the control and security of data, or if the business must bring services to market quickly, such as a web applications developer.[13] The first would opt for a private cloud for security peace of mind, while the web developer would choose a public cloud offering.[13] Most companies would operate a mixture the two, also known as hybrid cloud delivery.[13]

Employing a hybrid delivery cloud strategy[14] lets organizations use different cloud delivery services for specific applications.[15] For instance, a public cloud may be a more cost-effective service for the compute-intensive task of processing analytics, but the data would remain local, or private, to comply with regulations.[15] Because a hybrid delivery strategy lets organizations run applications and services across different clouds, collocation, and data centers, an example benefit of such a delivery mechanism is that organizations can move an app from one geographic location to another in major storms.[16]

There can be different types of hybrid clouds for specific tasks.[17] The Infrastructure as a Service (IaaS) model can be a hybrid cloud in that it could use operating systems and virtualization technologies from both a public and private cloud infrastructure to provide cloud services. Other models that mix on-premises cloud with public cloud technologies include Platform as a Service (PaaS), which includes infrastructure services combined with development tools and middleware; and Software as a Service (SaaS), which is used to develop packaged software.[17]

However, moving data in the cloud can be a difficult procedure.[18] In the case of Software as a Service (SaaS), it is difficult particularly if the incumbent cloud provider used proprietary software, or if it altered an open source application.[18]

A way to mitigate cloud migration difficulties is to architect applications for the cloud that reduce or eliminate the dependencies between the cloud application stack and the capabilities of the cloud service provider.[19] Another way is to select only generic and higher-level applications to move to the cloud in the first place.[19] Another method is to select open standards for cloud computing.[19]

A best practice for avoiding cloud migration problems is to use a management platform that can support applications in any environment a user organization is likely to use. This has been described as using a "best-of-breed" approach.[20]

Cloud professional services

Companies engage cloud professional services consultants to help them plan how to incorporate cloud services into their business operations. Consultants advise businesses on whether to use public, private, or a hybrid delivery model, and how they should implement or consume those delivery models.[21] For example, cloud professional services consultants might recommend that businesses interested in cost savings place appropriate applications in the public cloud, but keep a higher-security application in a private cloud or Hybrid cloud.[22]

In a 2013 competitive vendor analysis report by International Data Corporation, a market research firm, the authors state that cloud professional services can help companies map out both a short-term and a long-term strategy for how to use cloud in a way that aids their business goals.[21]

The most common reason businesses engage cloud professional services are for assistance with incorporating cloud technology into existing IT environments, and to plan how to implement cloud, according to a study published in February 2014 by the independent research firm Technology Business Research, Inc. According to published reports, the use of cloud professional services indicates that businesses do not have adequate internal resources that are knowledgeable about implementing cloud.[23]

Converged Cloud characteristics and components

Converged infrastructure

SAP Converged Cloud follows the premise of Converged infrastructure: the integration of compute, storage, and networking components and technologies into self-provisioning pools of shared resources, and supported by IT services.[24] One of the benefits of a data center based on converged infrastructure, including a converged infrastructure data center that delivers cloud services, is that manual tasks can be automated, thus reducing the time and cost to carry them out.[25]

Open standards

SAP Converged Cloud is supporting the VMware hypervisors. It supports multiple operating systems (Microsoft, Red Hat, Ubuntu, etc.) It supports a wide range of development environments. Being based on Openstack technology, means it is compatible with public cloud platforms based on OpenStack technology, such as RackSpace and Nebula.[26]
