Introduction to Software-Defined Data Center (SDDC)

Software-Defined Data Centers are the new era platform for centralizing organization operations. Housed in a secure in-house facility same as traditional data centers ensuring the data security and the platform remains up and running. SDDC methodology has been adopted by many organization for their current and future data center deployment. Organizations are moving from the traditional way of managing to the Software-Defined Data Center.

Why Software-Defined Data Center Matters?

Data centers are not easy to maintain and run. The traditional way of running datacenter requires a lot of workforces is not efficient. Adding new resources can take a lot of time, and almost everything is done manually. Scaling these data centers is quite difficult in terms of management and maintenance. Software-Defined Data Center provides a better way for management and scaling data center despite its size. Scaling data center horizontally is easier with the software-defined data center. It provides an organization with its private cloud for better control of hosted resources. Software-defined data centers capitalize on the agility, elasticity, and scalability of cloud computing.

What are the key features of Software-Defined Data Center?

The best features of Software-Defined Data Center are listed below:

  • Simplified data center management
  • Horizontal Scaling
  • Reduces administrator burden
  • Cost efficient
  • Automated Orchestration
  • Easier provisioning and monitoring of resources

How Software-Defined Data Centers (SDDC) works?

In SDDC, everything is software-defined including three major components of the stack
  • Storage
  • Network
  • Compute

Software-Defined Storage

Software-defined storage is an approach to which abstracts the management and orchestration layer from underlying physical hardware providing flexibility, scalability, reliability. Resource flexibility is paired with programmability to ensure storage adapts new demands automatically. Unlike traditional NAS or SAN system SDS is generally designed to perform on any standard x86_64 arch removing software dependency on proprietary hardware.

Software-Defined Networking

Networking is the major of the data center. The traditional way to managing network was complex and rigid for the vast network; the flow of system was from north to south. But the requirements have been changed requiring north to south and east to west traffic flow. Software-defined networking enables easier management as the control plane is programmable and manages all the networking hardware components reducing the effort of manual configuration of each element. The software-defined network focuses on the separation of the network control plane from the data plane.

Software-Defined Compute

Software-defined compute leverages the virtualization technology. It masks server resources, including the number and identity of individual physical servers, processors and operating systems from users by removing the load of managing complicated server-resource details. It also increases resource sharing and utilization, while maintaining the ability to expand capacity according to need and requirement.

How to adopt Software-Defined Data Center (SDDC)?

Many data centers have now adopted Software-defined data center across the globe. There are several services and products provided by vendors like VMware and dell for deployment. But some open source technologies are also available for the implementation of a software-defined data center which can scale horizontally according to requirement. Organizations like a red hat, canonical and use are providing support for the open source tools with their customization.

Software-Defined Data Center Best Practices

  • Use of virtualization
  • Use of hardware and software supporting rest API's
  • Infrastructure automation
  • Divide infrastructure in reusable components
  • A careful comparison of vendors
  • Start with small

Concluding Software-Defined Data Center

SDDC is based on the concept of virtualization and automation. The idea of the Software-Defined Data Center enables agility on the infrastructure side making the data center more flexible, scalable and efficient. Many product options are available from different vendors and open source communities for the deployment. But the selection of product and vendor depends on the business requirement.

What's Next?

Software-Defined Data Centers are the modern age platform for incorporating company services.  SDDC methodology is being opted by many organizations for their current and projected data center deployment. If you are planning to deploy this strategy, you are advised to take subsequent steps –
