VMware – Vendor Strengths and Cautions – Gartner

VMware

VMware has maintained its functionality lead, introducing vSphere 5.5 in September 2013 (it released vSphere 6.0 after the cutoff for this analysis). VMware continues to have dominant market share, and customers remain very satisfied with product capabilities and vendor support. However, concern over price and vendor lock-in remains. Client inquiries have been significantly increasing about comparisons between VMware and Hyper-V, specifically. While few large enterprises are switching, some smaller enterprises that are not far along in their virtualization deployment are switching (often from VMware to Hyper-V, but sometimes from Hyper-V to VMware), and some larger customers are deploying alternatives to VMware in separate data centers or in branch/store locations.

VMware is still enjoying good growth, but growth is harder due to both increasing market saturation and competitive pricing pressure. An emerging concern is the rapid growth of IaaS cloud providers, especially Amazon Web Services (based on Xen), used mainly for new workloads that are designed for cloud computing. While VMware has a dominant share for existing enterprise workloads, its share of the newer, cloud workloads is much smaller — a major inhibitor to growth. While the overall installed base of VMs tripled between 2011 and 2014, the percentage of VMs in cloud computing providers grew from 3% to 20% in the same time. VMware launched its own cloud service in August 2013 (now called vCloud Air), but it is still a very small player compared with providers like Amazon.

With respect to the growing midmarket business, in which high-end management and automation features are less critical, VMware has retained a strong market share. (Gartner surveys consistently show that about half of midmarket companies, those with 100 to 1,000 employees, tend to use VMware.) However, as Microsoft gains marketing momentum, VMware will need to continue to offer low-price packages to remain competitive in this market. As VMware promotes virtualization for more mission-critical workloads, it continues to face an Oracle VM solution, whereby concern over platform certification will drive a small number of VMware users to Oracle VM. While Windows-based workloads have become heavily virtualized, there is still quite a bit of opportunity for Linux-based workloads. However, OpenStack, Red Hat and containers are growing trends driving Linux virtualization.

A key for VMware’s growth will be to expand outside of traditional applications, attract and enable developers, and succeed as a cloud provider (and/or as an enabler to cloud providers).

Strengths

  • VMware has a broad virtualization strategy from the data center to the cloud.
  • VMware is a virtualization technology leader, with significant investments and innovation.
  • VMware receives high customer satisfaction from a large installed base.

Cautions

  • The cost of VMware offerings tends to be high.
  • VMware has a large number of third-party providers that offer VMware functionality, but the overall market share of VMware functionality in third-party cloud providers is small.
  • VMware has a low penetration for newer, “cloud-native” applications.

Biggest Game Changer Since Server Virtualization

Link : Storage Optimization Software for the Virtual Data Center.

Atlantis ILIO USX—Biggest Game Changer Since Server Virtualization

Deploy Up to 5X More VMs on Any Storage, Lower Costs by Up to 50%

Atlantis ILIO USX™ is a significant breakthrough in virtualization technology, delivering a solution that unlocks the underutilized capacity of over $50 billion of deployed enterprise storage, similar to what VMware did for server virtualization.

Atlantis ILIO USX software gives IT the flexibility to get more out of their existing storage, even their older arrays, and to create new software-defined storage hybrid arrays, hyper-converged systems, and all-flash arrays by aggregating and pooling existing server SSDs, SAS, flash, and RAM together with shared SAN/NAS arrays.

Architecture

Atlantis ILIO USX pools and optimizes server RAM, SAS, and/or Flash to create a highly scalable, hyper-converged platform using existing servers. Atlantis ILIO USX provides the flexibility to pool commodity local storage with RAM and/or flash across multiple server farms. By doing so, customers can seamlessly scale out their architecture to create a hyper-converged infrastructure and manage their applications without having to rip out their existing infrastructure.

Atlantis ILIO USX optimizes how storage is consumed by the application or VM by inserting a transparent software layer between the application and storage. The Atlantis ILIO USX software resides on the hypervisor platform as a set of virtual machines that can abstract any storage hardware into pools of virtual storage that can be combined together to form an Application Defined Storage Volume (ADS Volume). There are two types of storage pools:

  1. Capacity Pool: Any type of storage is pooled together to provide capacity for ADS Volumes. SAN, NAS, and local storage including SSD and Flash can be pooled in any combination to provide the underlying capacity required by applications and VMs.
  2. Memory Pool: High-performance server resources such as flash, RAM or even flash on DIMM are pooled and optimized to provide the performance required by the application storage volume. The memory pool can be used either as an optimization and acceleration tier or as primary storage for applications and VMs.

These Capacity and Memory pools are combined together automatically to create Application Defined Storage Volumes (ADS Volume) with policy-based controls that apply the ideal combination of storage capacity, performance and availability for the application. The ADS Volume provides enterprise-class storage functionality including high-availability, data protection, thin provisioning and cloning. Multiple ADS Volumes can be created from a single Capacity and Performance Pool, enabling true application-centric storage for the first time.

The Atlantis ILIO USX platform applies multiple storage optimization technologies to boost the performance and increase the available storage capacity provided to the application. At the same time, Atlantis ILIO USX dramatically reduces the impact of application IO traffic on storage resource utilization (disk, storage controller, network).

Use with existing Shared Storage

Use Local SAS or SATA

Use RAM as Primary Storage

Optimized All-Flash Arrays

In-Memory Architecture — Atlantis ILIO USX can run VMs completely in server RAM to deliver high-speed, low latency runtime storage without re-architecting applications

IO Processing — Atlantis ILIO USX processes IO operations in real-time at the compute layer to lower latency and reduce network traffic

Inline De-duplication — Atlantis ILIO USX performs inline de-duplication in real-time on-the-wire with microsecond latency, eliminating up to 90% of storage IO traffic

Real-Time Compression — Atlantis ILIO USX compresses the optimized blocks In-Memory with microsecond latency

IO Blender Fix — Atlantis ILIO USX coalesces small random blocks generated by the hypervisor into larger sequential blocks, greatly improving storage access and efficiency

High Availability — Atlantis ILIO USX provides integrated high-availability and data protection to prevent application downtime.

Thin Provisioning — All Atlantis ILIO USX storage volumes are automatically thin provisioned with up to 10:1 consolidation.

Fast Clone — Atlantis ILIO USX can clone full VMs in as little as 4 seconds with no network or storage traffic.
