While SDN and the SDDC are major technology building blocks for the private cloud, they require specific tools and approaches that enable management and provisioning of that private cloud. This is where VMware and its numerous integrated tools come into play.
The main use of vCenter is providing a single interface for the virtualized data center. It acts as the management interface for the vSphere hypervisor and management suite that includes the ESXi, which is the VMware hypervisor underlying infrastructure resources and the VMs.
VMotion enables the live migration of running virtual machines from one physical server to another and enables:
- Automatic optimization and allocation of resource pools for maximum hardware utilization and availability
- Hardware maintenance without any scheduled downtime
- Proactive migration of virtual machines away from failing or underperforming servers
Distributed Resource Scheduler (DRS) enables rules definitions for physical resource allocation among virtual machines either automatically or manually. Drastic workload changes prompt DRS to redistribute the virtual machines among the physical servers. If the overall workload decreases, some of the physical servers can be temporarily powered down and the workload can be consolidated.
High availability is paramount for systems and applications, so the ability of VMware vSphere HA (High Availability) to restart failed virtual machines (VMs) on alternative host servers reduces application downtime. VMware DRS and vSphere HA work together for workload rebalancing. The use of vSphere HA and DRS together can keep restarted VMs from affecting the performance of other VMs on the failover host.
VMware Fault Tolerance provides continuous availability for virtual machines by creating and maintaining a secondary VM that is identical to, and continuously available to replace, the primary VM in the event of a failover situation. You can enable Fault Tolerance for most mission-critical virtual machines.
Consolidating Hardware via Bare Metal Hypervisor
The VMware ESXi bare metal hypervisor facilitates physical server installation and the access and control of its underlying resources. It also enables hardware partitioning for reduced hardware costs, among other features. ESXi delivers a host of benefits through:
- Hardware consolidation and increased capacity utilization
- Increased application performance
- Centralized IT management
- Reduced CAPEX and OPEX
- Minimized hardware resources needed to run hypervisor for cost savings and more efficient utilization
This alleviates a great deal of the pressure on IT teams that work with limited budgets and need to implement other vital, complex projects.
SDN Virtual Networking and Security
VMware NSX is the network virtualization platform for the SDDC. With NSX, network functions—including switching, routing, and firewalling—are embedded in the hypervisor and distributed across the environment. This effectively creates a network hypervisor that acts as a platform for virtual networks and service by providing:
- Individual workload micro-segmentation and granular security
- Reduced network provisioning and improved operational efficiency through automation
- Workload mobility independent of physical network topology within and across data centers
- Enhanced security and advanced networking services through third-party vendor solutions
Cloud Management and Monitoring
The role of management and monitoring is crucial for private clouds, and VMware provides numerous tools to accomplish this.
VMware vRealize Suite Operations Benefits
vRealize is designed to help IT administrators build and manage heterogeneous, hybrid clouds by providing:
- Unified monitoring
- Automated performance management
- Cloud planning and capacity optimization
VMware vCenter Log Insight
vCenter Log Insight is a virtual appliance that allows administrators to view, manage, and analyze system log data including log consolidation, monitoring and troubleshooting vSPhere, and performing security auditing and compliance testing.
VMware Cross Cloud Architecture
Cross Cloud Services enable management of all cloud deployments for an organization. This single-pane-of-glass approach enables a common VMware operating environment across private and public clouds.
VMware vSphere Replication
VSphere Replication automates the replication of virtual servers to a recovery site, and when used in conjunction with VMware SRM, gives businesses a strong BCDR foundation.
VMware vCenter Converter
VCenter Converter can convert Windows- and Linux-based physical machines and Microsoft Hyper-V systems into VMware virtual machines.
VMware SDDC provides all of the software needed for building an enterprise infrastructure that is flexible, easy to manage, and easy to change for future needs. By virtualizing storage and networking, in addition to compute, SDDC is less dependent on physical hardware. Together with VMware vRealize Automation and NSX, enterprises can easily control, manage, provision, and orchestrate multi-cloud environments that are a mix of private and public.
