Virtual Private ServersDedicated server resources and performance,

without dedicated server prices.PRESENTED BY:

Current choices in hosting…

Shared Server Hosting

PROS:• Inexpensive• Simple• Commonly available

CONS:• Restrictive• Sharing server resources• “Living with your neighbors”• Growth becomes expensive

Dedicated Server Hosting

PROS:• 100% CPU/memory resources• Flexible configuration• Lots of storage & bandwidth• Can host unlimited domains

CONS:• Expensive• More difficult to manage• Long term commitment

The Next Big Thing - VPS

What is a Virtual Private Server (VPS)?

Virtual Private Servers are the most advanced step in server virtualization technology. They are used to partition a single physical server into many isolated virtual environments, each with full server functionality.

Each virtual private server looks and behaves exactly like a real networked server system, complete with its own set of init scripts, users, processes, filesystems, server applications, etc. Complete isolation ensures that the virtual environments are secure and have full functional, fault and performance isolation.

VPS and web hosting: Virtuozzo

Virtual Private Server (VPS) with Virtuozzo OS-level virtualization and automation creates isolated partitions or virtual environments on a single physical server and OS instance to utilize hardware, software, datacenter and management effort with maximum efficiency. Intelligent partitioning divides a server into as many Virtual Environments as the server CPU and memory allows, all with full dedicated server functionality.

Virtual Private Server offers a perfect balance between total control(root access), performance, security and economy to control youronline presence. VPS fills the gap between shared hosting and dedicated server, with all the benefits of a dedicated server but without the monthly cost and management expense.

What does it look like?

VPS basics

• VPS behaves exactly like an isolated stand-alone server• VPS appears to have its own processes, users, files and provides

full root access• Each VPS has its own IP addresses, port numbers, IP tables,

filtering and routing rules• Each VPS can have its own configuration files for the system and

application software• Each VPS can have its own versions of system libraries or modify

existing ones• Each VPS can delete, add, modify any file, including files in /root,

and install its own application software or custom configure/modify root application software

Architecture: Virtual Hosting vs VPS

Virtual Hosting

- Shared Applications- Limited Control- Shared Environment- Shared Web Server- Shared Mail Server- Shared Database Server- Shared FTP Server

VPS Hosting

- Install your own applications- Administrative Control (root-like)- Independent Secure Environment- Dedicated Web Server- Dedicated Mail Server- Dedicated Database Server- Dedicated FTP Server

VPS - Quality of Service

Quality of Service to provide dedicated SLAs for each VPS:

• StandardIncludes CPU, disk space and network guarantees

• UniqueGuarantees on memory - user and kernel, physical and virtual

• UniqueGuarantees on disk I/O and many other critical resources (over 20)

Main VPS benefits over shared hosting• Control:

A Virtual Private Server gives you root access to the system, this allows you to modify server configuration files, install applications or modify system software; in a shared environment you have to rely on server settings that are 'best fit' for all clients and this may not suit your needs.

• Security:With a Virtual Private Server your file system is not accessible or viewable by any other VPS owner, unlike a shared environment where anyone with shell access can browse through your files. VPS ensures full privacy and security.

• Isolation:In a shared hosting environment you are 'held hostage' to the actions of others; if another shared account runs a script that crashes the server then your site goes down too. With a Virtual Private Server you have complete resource isolation, no matter what another VPS user does - it will not affect your virtual server.

• Performance:In a shared environment resources go to the site 'that shouts the loudest' - in other words a big site can drain all resources and leave yours performing poorly. In a Virtual Private Server environment you are guaranteed a set of resources to ensure your site always performs at full speed. These resource guarantees ensure other Virtual Private Servers have no affect on the performance of your site.

Main VPS benefits over dedicated server• Cost:

A virtual private server gives you all the functionality of a dedicated server at a fraction of the cost.

• Data Integrity:With a Virtual Private Server you get built-in incremental backups on top of a world class RAID-5 or RAID-10 array to ensure data integrity and recovery.

• Management:The nature of a Virtual Private Server means we can manage all aspects of software upgrading and patching, no need to worry about updating your packages - it is all controlled by us, your hosting company.

• Functionality:A Virtual Private Server is functionally equal to a dedicated server.

• Resource Efficient:You get the resources you need when you need them and all resource guarantees are instantly scalable to suit your needs as you grow.

Advantages of a VPS

• Performance (no virtualized hardware, suitable for high I/O applications)

• Scalability (can scale up to 100% of server resources)

• Density (from web hosting company perspective)

• Consolidated OS and Application Management• Ultra Fast and Parallel Operations

(create, restart, update, resize, backup/restore, migrate, clone)

• Dynamic Resource Allocation (change heavily detailed VE resource parameters in real-time)

• Management Suite of Tools(convert, provision, monitor, backup, recover, analyze, repair, migrate, self-manage)

• Live Migration (physical to VPS, VPS to VPS)

• Broad Platform Support• Detailed Resource Management

Shared hosting vs VPS

• Choice of control panel Shared

NoNoNoNoNoNoNoNoNoNo

VPSYesYesYesYesYesYesYesYesYesYes

• Brandable control panel• QoS Guarantees (CPU, memory, bandwidth)

• Choice of Linux or Windows distributions• Scalable (ready for rapid growth)

• Root access• Custom modules / software• Reboot server & Restart services• Sandboxed from other users• Personal, customizable firewall

What you get with VPS

• Total control• Security & separation from all other VPSs and other clients• Performance guarantees; allocation of server resources• Flexibility to set up anything you want or reconfigure your own VPS• Ability to reboot or reinstall your VPS without affecting the server• Repair the base OS and control panel, without reloading web sites• Host unlimited domains, use any web control panel• Very easy to upgrade VPS resources without moving sites• Far less expensive than a dedicated server• Moving from VPS to dedicated server (if/when you outgrow the VPS

solution) is easy• Migrating from shared server (ANY platform) to VPS can be automated
