Virtuozzo 7 webinar October 18

  Today i was on very cool Virtuozzo 7 webinar (October 18 2016) and it was astonishing!!!

I am using Virtuozzo products since version 4.6 and i see very big potential in Virtuozzo 7 for big hosting company and for little – it think its the most cost-effective solution for VPS and cloud hosting.

One of the great (for me?) features that i was surprised to her (BETA stage?) – Disk encryption ! You can encrypt the data and the backup and the container would be encrypted  🙂 I think ReadyKernel is the second of the greatest things – No more “useless” Reboots !!! 🙂

One more likely the saddest news to hear was – “No more PVA”.  Yes , you are not in the dream… Virtuozzo killing its “baby” for new product that called “Virtuozzo Automator”. Virtuozzo team says that Virtuozzo Automator will have brand new features like LB (Load Balancer) , VPN , Network config and more ….

I remember a great story regarding Plesk Expand server – it was one of the best support hosting panels ever… some day Plesk (Paralles) decide to “kill” this solution and what is happening now is a mess, support department was confused with so many plesk panels…. Couple of years past and now Plesk (Paralles) developed “New Expand” as extension to Plesk platform that do the same thing … . I think the same would be with PVA (i think so…..)   🙂

Virtuozzo 7 – Highlights

  Virtuozzo Containers – whats new in Virtuozzo 7 ?

With system containers™, a single operating system kernel can support multiple isolated virtualized instances instead of just one. Such instances, called containers™, look and feel like a real server from your customer’s point of view.

Key Features

Designed to run a full Linux OS and any distribution

Low memory overhead; advanced memory management

Flexible and fine-grained CPU and memory management

Secure by default

Benefits

Better performance and density compared to VMs

Containerize any application with native performance

Support for container™ management through libvirt and OpenStack

By the Numbers

60% better performance compared to VM

2x greater density compared to VM

Deploy hundreds of containers on a standard dual-CPU x86 server

Zero overhead costs

Fraction-of-a-second startup time

Measuring System Container™ Density

This graph depicts a density test comparison of CentOS 7 KVM and Virtuozzo 7 Containers™. Each virtualization solutions was loaded by a number of clients sending requests to every server at fixed rate. While adding more and more servers, we monitored the average response time and stopped the test when it reached the preset limit (200ms). As you can see, CentOS 7 KVM was able to handle 130 servers simultaneously, while Virtuozzo Containers™ can run more than 200 servers with the identical performance.

Powerful guest tools

Benefits

Proven backup solution shipped by default

Reduced overall maintenance

Low cost

Software-defined storage runs together with compute

Upstream compatible and commitment to open standards

By the Numbers

100% upstream KVM compatible

Up to 40% better performance results for latest Linux and Windows OS

30% higher density than standard KVM

24×7 highly skilled professional support

Performance Test: CentOS7 KVM vs Virtuozzo 7 Hypervisor

This graph depicts a SPECvirt performance test of Linux workloads for CentOS 7 KVM versus the Virtuozzo 7 Hypervisor. Tiles represent a set of workloads. A single tile deploys a number of different workloads, each of them generating output transactions. Here we measure the output total of all transactions.

  Virtuozzo 7 Storage – whats new ?

Key Features

High availability, high performance

Low-cost scalability up to multiple petabytes and hundreds of nodes in a single cluster

Block storage optimized for big files; S3-compatible object storage

Web-based UI management

Benefits

Use your existing hardware

Flexibility to deploy containers and VMS

Fast performance

Zero downtime

Live server migration in user space

Eliminate the need for costly, special-purpose storage devices
