VMware is a company that provides cloud computing and virtualization software and services. VMware has several products that provide organizations with advantages in running and managing their IT infrastructure and applications in software defined data centers.
Some of the key advantages of using VMware products and solutions include:
Flexibility and portability
- VMware’s virtualization technology allows multiple operating systems and applications to run on the same physical server at the same time. This provides more efficient use of computing resources.
- Virtual machines can be moved between different physical servers with no compatibility issues. This makes it easy to move workloads as needed without disruption.
- The virtualization layer abstracts hardware, so virtual machines are not tied to specific physical servers. They can be moved and scaled as needed.
Increased efficiency and utilization
- Rather than running each application on a dedicated server, VMware allows you to consolidate multiple applications onto fewer servers. This increases hardware utilization.
- Resources like CPU, memory, and storage can be allocated dynamically based on real-time needs. This allows adjusting resources for optimal performance.
- Automated load balancing across servers ensures maximum usage of resources across the data center.
Improved availability and disaster recovery
- In case of server failure, virtual machines on that server can be automatically restarted on other available physical servers. This provides built-in failover and redundancy.
- Snapshots allow you to easily roll back virtual machines to previous known working states in case of issues.
- VMware’s High Availability (HA) capability can detect server failures and automatically restart virtual machines, reducing downtime.
- VMware’s vMotion capability enables live migration of virtual machines between physical servers with no downtime or performance impact.
Enhanced security and isolation
- VMware offers a virtual firewall to protect each virtual machine and its traffic. This micro-segmentation isolates virtual machines for improved security.
- VM encryption protects data at rest. VMware also supports data encryption in motion.
- The hypervisor provides strong isolation between virtual machines on the same physical server.
- VMware’s AppDefense can monitor virtual machine behavior and traffic to detect and respond to threats.
- The vCenter Server provides centralized management, monitoring, and automation across the VMware environment.
- Migration, provisioning and modification of virtual machines can be done through software without physical access to servers.
- APIs and SDKs allow integration and automation with third party management tools and processes.
- Support for software defined networking simplifies management of virtual networks.
Key Components and Products
VMware offers a broad portfolio of products and services that provide the advantages discussed above. Some of the major components and products include:
vSphere is VMware’s virtualization platform. It provides the fundamental compute virtualization layer that allows multiple virtual machines to share physical resources. Key components of vSphere include:
- ESXi Hypervisor – This thin hypervisor is installed directly on bare-metal physical servers providing virtualization.
- vCenter Server – vCenter provides unified management and automation across all ESXi hosts through a single pane of glass.
- vMotion – Allows live migration of virtual machines between ESXi hosts with no downtime or performance impact.
- High Availability – Automatically restarts virtual machines on alternate hosts in a cluster if the original host fails.
- Distributed Resource Scheduler (DRS) – Load balances and allocates resources dynamically based on real-time utilization data.
vSAN provides a distributed storage platform, delivering shared storage for virtual machines across the vSphere cluster. It aggregates local storage from servers to create one pool of storage:
- Reduces need for external shared storage like SANs.
- Provides high performance by leveraging flash drives on the server.
- Seamless scaling by adding more standard servers to increase capacity and performance.
NSX is VMware’s network virtualization platform. It abstracts physical networks and provides software defined virtual networks:
- Allows micro-segmentation and isolation of workloads across virtual networks.
- Supports security policies that follow workloads across networks.
- Provides logical switching without dependency on the physical network topology.
- Integrates with other VMware components through API integration.
VMware vRealize Suite
vRealize includes hybrid cloud management, automation and operations software tailored to VMware environments:
- vRealize Automation for automating infrastructure and application delivery.
- vRealize Operations for performance monitoring and management.
- vRealize Log Insight for log management and log analytics.
- vRealize Suite Lifecycle Manager to manage vRealize components as a unified platform.
