In a nutshell, the converged infrastruc- ture is a more hardware-focused approach to simplifying the datacenter. All compo- nents—storage, compute and network- ing—are fully integrated, but able to be separated and work independently. The hyperconverged infrastructure is a software-defined approach to the datacenter. The components more fully integrated. There also tend to be more components—besides the classic compute, storage and networking. The infrastructure may include components like WAN optimization, data compression and storage virtualization. Performance and management functions like caching, pooling and capacity optimization are built-in. The chart below clearly explains the differences. CLOUD MADE EASY WITH HYPERCONVERGED INFRASTRUCTURE The Cloud First mandate has made it clear federal agencies must move at least some of their workloads to the cloud. In some cases, it can be difficult to make that leap. It means figuring out what technology to use, how it will integrate with the rest of the IT infrastructure, and how to create the most efficient and safe cloud scenario. It’s even more difficult when the applications and data involved are sensitive and require a secure private cloud environment. A hyperconverged infrastructure reduces or eliminates many of those challenges. Because a hyperconverged infrastructure contains everything necessary to stand up a cloud, it’s easy to deploy a secure private cloud in just a few hours. It’s also simpler to start small and scale to hundreds of nodes or more and back again as needed. It simplifies connecting to public cloud providers like Microsoft Azure or Amazon S3. For private clouds, some vendors now offer “cloud-in-a-box” solutions to help IT organizations stand up private clouds quickly. These solutions include all the requisite compute, storage and networking tools, as well as a management console. This console lets agencies fully control where data resides and who has access to specific data sets. Because hyperconverged infrastructures support both public and private clouds, they can be a particularly useful in cases where some applications and data must remain on-premises. Other agencies can take advantage of the public cloud. That’s the situation with most agencies. IDC Government reports the federal government will spend as much as $3.4 billion next year on cloud solutions. A healthy portion of that will be spent on hybrid cloud solutions. “HYPERCONVERGED SYSTEMS WILL BECOME THE NEW STANDARD FOR INFRASTRUCTURE-AS-A-SERVICE DEPLOYMENTS” —REPORT FROM FORRESTER RESEARCH, MARCH, 2015 CONVERGED HYPERCONVERGED Approach Hardware-based Software defined Components n Networking n Compute n Storage n Server virtualization n IT infrastructure management software n Networking n Compute n Storage n Expanded IT infrastructure mgmt. n Server hypervisor Additional capabilities n WAN optimization n Storage controller attached to each VM at the hypervisor layer n Data deduplication and/or snapshots n Built-in virtualization n Caching n Inline compression n Capacity optimization n Auto-tiering n Primary storage data deduplication Benefits n Prebuilt and supported as a single entity n Components can be decoupled if necessary n Can be expanded by adding additional building blocks n Full visibility and manageability at the VM level n Allows for resource pooling and sharing n Tighter integration of components through software n Policy-based protection and resource allocation at the VM level n Greater scalability and resilience n Can be customized GameChanger GAME CHANGING TECHNOLOGY TO MEET AGENCY MISSIONS SPONSORED REPORT HYPERCONVERGED INFRASTRUCTURE 0815_GameChanger_Nutanix_FCW_final3.indd 2 8/21/15 3:10 PM
