Software-defined data center

1 'Software-defined data center (SDDC)' is a vision for IT

infrastructure that extends virtualization concepts such as

abstraction, pooling, and automation to all of the data center’s resources

and services to achieve IT as a service (ITaaS).



1 In a software-defined data center, all elements of the infrastructure —

networking, storage, CPU and security – are virtualized and delivered as a

service. While ITaaS may represent an outcome of SDDC, SDDC is differently

cast toward integrators and datacenter builders rather than toward tenants.

Software awareness in the infrastructure is not visible to tenants.



1 Because it is a vision with many possible implementation scenarios, SDDC support can be claimed by a wide variety of approaches. Critics

see the software-defined data center as a marketing tool and “software-

defined hype”, noting this variability.



1 Analysts project that at least some software-defined data center components will

experience strong market growth in the near future. The software-defined networking market is expected to be valued at about

USD $3.7 billion by 2016, compared to USD $360 million in 2013. International Data

Corporation|IDC estimates that the Software defined storage|software-defined storage

market is poised to expand faster than any other storage market.


Software-defined data center - Description and core components

1 The software-defined data center encompasses a variety of concepts

and data center infrastructure components, and each component can be provisioned, operated, and managed through an application programming interface (API). The

core architectural components that comprise the software-defined data

center include the following:https://store.theartofservice.com/the-software-defined-data-center-toolkit.html


1 * Management and automation software, enabling an administrator to provision, control, and manage all

software-defined data center components.



1 A software-defined data center is not the same thing as a private cloud,

since a private cloud only has to offer VM self-service, beneath which it

could use traditional provisioning and management. Instead, it imagines

the data center that can encompass private, public, and hybrid clouds.


Software-defined data center - Origins and development

1 Realizing the promise of the software-defined data center could

“only begin to happen now,” because until recently data centers lacked the

compute, storage, and networking hardware with the capacity to fully

accommodate virtualization.


Software-defined data center - Origins and development

1 Some observers believe that companies began laying the

foundation for software-defined data centers with virtualization. Ben Cherian of Midokura considers

Amazon Web Services as a catalyst for the move toward software-

defined data centers because it


Software-defined data center - Potential impact

1 the traditionally infrastructure-centric data center, with its focus on ensuring the

proper operation of compute, network, and storage elements, into an application or business service focused environment.…The [software-defined data center] purely

revolves around application workload demands, allowing business users to

deploy and run their applications in the most efficient and SLA compliant manner.



1 The potential of the software-defined data center is that companies will no longer

need to rely on specialized hardware or hire consultants to install and program hardware

in its specialized language. Rather, IT will define applications and all of the resources they require—including compute, storage, networking, security, and availability—and

group all of the required components to create a “logical application.”



1 Commonly cited benefits of software-defined data centers include

improved efficiencies from extending virtualization throughout the data

center; increased agility from provisioning applications quickly; improved control over application availability and security through

policy-based governance; and the flexibility to run new and existing applications in multiple platforms

and clouds.



1 In addition, a software-defined data center implementation could reduce a company’s

energy usage by enabling servers and other data center hardware to run at decreased

power levels or be turned off. Some believe that software-defined data centers improve

security by giving organizations more control over their hosted data and security levels, compared to security provided by

hosted-cloud providers.



1 The software-defined data center is likely to further drive down prices for data center hardware and challenge

traditional hardware vendors to develop new ways to differentiate

their products through software and services.


Software-defined data center - Challenges

1 The concepts of software-defined in general, and software-defined data

centers in particular, have been dismissed by some as “nonsense,”

“marketecture,” and “software-defined hype.” Some critics believe that only a minority of companies with “completely homogenous IT

systems’” already in place, such as Yahoo! and Google, can transition to

software-defined data centers.https://store.theartofservice.com/the-software-defined-data-center-toolkit.html


1 According to some observers, software-defined data centers won’t necessarily eliminate challenges that

relate to handling the differences between development and

production environments; managing a mix of legacy and new applications;

or delivering service-level agreements (SLAs).



1 Software-defined networking is seen as essential to the software-defined data center,

but it is also considered to be the “least mature technology” required to enable the software-defined data center. However, a number of companies, including VMware,[http://www.cypherpath.com Cypherpath

Inc.], Arista Networks, Cisco, and Microsoft, are working to enable virtual networks that

are easily provisioned, extended, and moved across existing physical networks.



1 [https://wiki.openstack.org/wiki/Neutron Neutron], the networking

component of the open-source OpenStack project, is considered an

important piece of the standards puzzle and is expected to play a key role in the evolution of the software-

defined data center



1 The software-defined data center approach will force IT organizations

to adapt. Architecting software-defined environments requires rethinking many IT processes—

including automation, metering, and billing—and executing service

delivery, service activation, and service assurance.


Software-defined data center - Current status

1 Other vendors are developing components and standards that enable the software-

defined data center


Software-defined data center - Current status

1 Large-scale service providers such as Amazon and Savvis, which could potentially benefit from improved

efficiencies through automation, are considered to be the organizations that are most likely to deploy full-scale software-defined data center

implementations.

Software-defined storage

1 VMware, which bought Nicira, used the term software-defined data

center (SDDC) for a broader concept wherein all the virtualized storage,

server, networking and security resources required by an application

can be defined by software and provisioned automatically.
