The difference between VMware and Virtuozzo Containers is more than just the name. Only hosting companies using VMware can offer complete flexibility, security and capacity, as well as options for high availability, load balancing and disaster recovery.

Operating System Flexibility

A basic difference between VMware and Virtuozzo is that VMware creates individual virtual servers directly on the hardware, at a bare metal level, while Virtuozzo’s containers run at the operating system (OS) level.

All container environments running on the same physical hardware must share the same host operating system. This means that while each environment can run its own client OS, the one you can run on your virtual environment will be limited to those that are compatible with the host. Virtuozzo is limited to Linux or Windows at both the host and client level, and can only run a client OS on a physical server that uses the same host OS; in other words, a Linux client on a Linux host, and a Windows client on a Windows host. Of course, limiting the operating system also limits your choice of software to that available for Linux and Windows.

Running at the hardware level, VMware accomplishes virtualization by using a physical machine’s hardware resources to serve multiple virtual servers, each of which can run an independent operating system. In this way, VMware virtualization supports many diverse operating systems on any server system. This allows VMware to support a variety of Windows versions and many different flavors of Linux, including Ubuntu, SuSE, and Red Hat, as well as non-Windows and Linux operating systems such as Solaris and Netware.

With Virtuozzo, because your virtual environment must run the same OS as the host, you don’t have the option to manage and modify your own operating system. The need for uniformity extends to updates—all environments must run at the same patch level. That means that if your virtual environment’s software has not been optimized for the latest Windows or Linux update, and your hosting company installs it (on the host system and across all virtual environments), your software may function poorly, or not at all.

With VMware, you can manage and modify your own operating system, as well as run different patch levels than the host system. This offers your company installation and update control on your virtual servers, and the freedom to use an extended range of software, software releases, and even multiple software flavors on the same OS, such as SQL Standard, Web and Express editions.

In Virtuozzo’s containers, when you need to reboot your virtual environment, such as during a test phase, you’ll have to wait for a scheduled system outage for the entire physical server, chaining you to your hosting company’s calendar. Using VMware, you can reboot your operating system when and as often as your situation requires.

Finally, a hardware-based virtual server like VMware offers something an OS-based virtual environment does not and cannot offer—virtual memory. Virtual memory, called swap in Unix or page file in Windows, allows your applications to use an assigned piece of disk space as working memory when necessary to avoid crashing. Because all container environments share an operating system core, containers don’t have independent access to swap. Using VMware, your hosting provider can give you swap space or a paging file as large as that available on a physical server.

Security

Virtual environments that all run the same operating system are more vulnerable to both security breaches and simultaneous code faults. If the virtual servers on a hosting physical server are all running one operating system, and any of the operating systems are hacked, then they all are; if the host operating system experiences a failure due to a bug in the software, then they all do. This is not the kind of virtual server environment you can depend on to failover gracefully or recover quickly.

In a Virtuozzo environment, security is complicated by the need for OS patches to be certified by the company. That means that when a critical operating system patch is released, the patch must go through another layer of complexity and time before it is applied—time in which your virtual server could be vulnerable. If your servers are hosted on VMware, you can apply patches as soon as they are released.

On-Demand Capacity

Because a VMware virtual server can operate on any physical server in the network, and because VMware supports live migration or vMotion, your whole virtual server can be moved as needed to another piece of hardware—with no downtime. This saves your company data and time, and it could save you customers and money. It also means that when your hosting company needs to take a physical server down for maintenance or replacement, you never need to know. Unlike in an OS virtual environment, live migration will allow your virtual server to continue running on the hosting company’s other servers. This is a feature that Virtuozzo still does not have.

High Availability, Load Balancing and Disaster Recovery Options

VMware virtual server lets your hosting company offer high availability, load balancing, and disaster recovery, unlike OS virtual environments. With VMware, your hosting company can offer load balancing, so your workload can run on the physical server that suits your needs during peak times.

With an OS-level environment, it might be impossible to move live data from one server to another. Even with compatible operating systems, the server might require a reboot.

When You’re Looking for Virtual Server Hosting, Think Infinitely Virtual

Virtual Server platforms aren’t all the same, and your hosting company needs to use the most flexible, secure and available virtualization technology. VMware, which runs virtual servers at the hardware level, is that technology.

Virtualization helps server hosting companies save money by allowing server functions to live on fewer physical machines, saving space, power, maintenance, and up front acquisition costs. VMware takes virtualization further; its bare metal hypervisor runs more efficiently than OS-based virtualization, allows more processes to run with less operating system overhead, and offers many operating system choices for virtual machine users.

Now, with the introduction of vSphere 4, VMware’s newest datacenter virtualization platform, VMware offers big savings for both virtual server hosting companies—and their customers—though higher server consolidation, reduced power consumption, denser storage, and lower maintenance requirements, all while supporting more virtual machines.

Doing More of What Virtualization Does

vSphere offers more of VMware’s money-saving features to lower the costs per virtual server and reduce environmental impact through more efficient server consolidation, dynamic power scaling, and higher bandwidth networking.

vSphere supports hardware equipped with up to 64 logical processing cores, 256 virtual CPUs and one terabyte of RAM per host, so more virtual machines can be operated in less physical server space. In addition, support for AMD Rapid Virtualization and Intel Extended Page Tables allows consolidation rates to be increased. With the ability to increase substantially the number of VMs on each physical server, hosting companies achieve economies of scale more quickly, leading to lower costs, and in many cases, lower prices.

Direct savings also result from lower power consumption and reduced infrastructure. Dynamic voltage and frequency scaling reduce power costs, and by implementing 10 gbps Ethernet and vNetwork Distributed vSwitch, hosting companies can drastically reduce network complexity. This reduction in complexity leads both to lower equipment acquisistion costs and a reduction in staff the required to install and maintain the network. This allows the VMware based hosting company to operate more cost-effectively, which in turn can be used to offer better service for less money. Finally, vStorage Thin Provisioning allows your hosting company to increase storage density, resulting in lower cost per GB of storage.

With competitve pressures, a VMware-based server hosting company can pass the savings achieved with vSphere on to its customers. If you’re looking for dedicated server hosting, a hosting company using vSphere can achieve higher consolidation ratios through support of higher density hardware per host, enabling it to pass the savings on to its customers in the form of lower rates for each virtual machine.

Deploying Google’s Gmail for my internet marketing business has allowed minimal and secure IT administration of my 8 websites (28+ email accounts). Supporting a mixed operating environment which includes Microsoft, Ubuntu and MacOS, multiple browsers, and document file formats from Microsoft Office, Open Office is made possible and easier with an in-the-cloud computing environment like Gmail.

So why would you consider cloud computing like Google Mail for your business, especially an SME (small medium enterprise)?

In a two words – security and compliance. E-mail security, web security and message compliance are the underlying benefits to solid business reasons to have your mail and office documents served through Gmail.

Compliance to Security and Retention Requirements

Whether your organization is 1 person or thousands of people in size, you are faced with accounting, legal and government regulations and standards that dictate acceptable levels of IT security and records retention for all electronic files and e-mails. Gmail can help ensure compliancy plus provide you with real business benefits in streamlining your document and email management. Deploying Google Mail is just smart business. Some benefits include:

1) Organizing and Filing (Archiving) your email the anyway you want it.

Google uses labeling as a way to file and organize your emails. You can tag an email with multiple labels. For example, an email from your accountant with tax information could be label as “Corporate Taxes”, “Accountant”, “IRS”, “Revenue Canada”. Gone is the restriction of having to choose only one file folder to which you move an email.

2) Keeping Email conversations or threads linked together.

Appearing like cascading file folders, emails on the same topic (subject) will be kept together in your inbox or to the multiple archived labels you have assigned. No searching for the email trail or thread of emails about a particular subject. They are visually represented like a group of stacked file folders.

3) A free unlimited storage repository for all your email and messages forever!
At 7 gigabytes per gmail user account and growing as of August 2008, the Google mail tagline is ‘ you’ll never need to delete another message’.

Takin’ Care of Business, instead of computer or IT Administration

Reducing the time spent on administration of your computer storage, security, backup and recovery allows you to spend more time building your business. Manage all your email accounts entirely from within one or two Gmail addresses. Once set-up, Gmail offers this low administration environment.

4) No Mail is downloaded or stored on your server, desktop, laptop or PDA. This eliminates any stress or administration angst associated with:

– searching for emails stored and scattered across multiple client devices – some emails on your PC , some on your laptop, some on your PDA

– scheduling backups of your email, contact list and documents

– recovery (and loss) of email & documents due to client device loss, failure or theft
– expanding storage capacity due to continuing email and document growth and retention
– remote or mobile access for all your email, attachments and documents

– managing, consolidating and keeping intact multiple email addresses and personalities
– off-site backup of select files for SOHO or Small Businesses

Document creation, management and simple online collaboration

5) Use Gmail online Office Suite to create, manage, store your business documents, spreadsheets and presentations. Read and write Microsoft Office formatted documents as well as all the open document variants. Securely stored at Google, eliminate HDD file storage and backup. No more MS Office licensing fees to Microsoft.

6) Store images and pictures using Picasa Web Albums. Manage your images on your PC using FREE Picasa Software – crop, adjust, special effects.

7) online chat and messaging integrated, stored and managed just like your email.

Reducing the complex e-mail security threats to your corporate data

8) Google yet again has an very intelligent SPAM filter that checks each message content and therefore does not arbitrarily blacklist the email address, just the specific email due to content. No emails are downloaded to your PC or an office application; therefore, no waste of bandwidth or risk of infected emails on your hard drive.

9) Google’s anti-virus checking is also performed away from your computer. All attachments are checked at the Google server for viruses and, if infected, flagged/moved to SPAM right away. No infected e-mail ever arrives on your computer’s hard drive.

Traditional server or computer-based email systems download ALL your email, passing it through a spam/anti-virus filter on your computer. This is a waste of bandwidth usage (downloading spam email) and, even worse, exposes you to the additional risk of having spam and virus-infested e-mails get closer to your data files on your computer hard drives?

So why you need to seriously consider using Google Mail for all your office needs?

– Complete office mobility – via any browser, access to your email, documents, images, chat

– Access anywhere, anytime through any browser

– No backups required of email, office documents or contacts

– Manage multiple user profiles and email accounts in one convenient place

– Includes Anti-Spam and Anti-virus checking away from your PC, Laptop or Server

– Gmail Free Unlimited file space

– Next to No Mail Administration.

Gmail is the perfect Mobile Office Utility for Small Medium and Enterprise businesses. Google Mail Cloud Computing environment will allow you to focus on your business operations and growth. Implementing the Gmail in-the-cloud computing model for your email security and compliance makes a whole lot of sense.

Keep your head in the clouds!

Three dimensional printing, AKA desktop producing, rapid prototyping, solid freeform fabrication, solid freeform fabrication or layered manufacturing, has always been in the leading edge of development and design.

Come visit us right here for more Rapid Prototype Info and get two Prototyping Ebooks Sls Prototypes.
http://www.prototypezone.com/

By quickly making prototypes that are similar to form and function as the particular production unit, developers are able to make a product that lives up to the expectancies of consumers and project sponsors.

Through a mix of rapid prototyping techniques and traditional model making, top of the range prototypes can be created with less the cost and quicker implementation times.

Compared to traditional fabrication strategies like milling and turning, layered manufacturing is significantly better re accuracy, speed and quality. By trying three dimensional printing methods intricate and complex shapes can be formed without any advanced machine setup, prototypes can be made from differing kinds of materials or composites, and the process simplifies the entire process of making a prototype.

Because of the advantage it brings, desktop manufacturing services are being offered by corporations to engineers and system developers to better understand their product and communicate better with their target customers. Not only will the technique utilized by designers, developers and makers, but professions like surgeons, designers, artists and even mere individuals regularly employ the technology.

Among the services being offered are stereolithography, selective laser sintering or SLS, fused deposition modeling of FDM, laminated object manufacturing or LOM, inkjet-based systems and layered manufacturing or 3DP.

SLS is one of the most used tools in rapid prototyping methods. In SLS solid freeform fabrication, a CO2 laser is used to melt powdered thermoplastic materials to create layers. A scanner guides the laser and melts particular areas and materials based mostly on the info fed by the 3D CAD.

Prototypes made from SLS processes are robust and more long suffering to stress. Materials used in the market include DuraForm, CastForm, Somos 201, FR85A and LaserForm. The majority of the prototypes created from these materials are sometimes prepared to be used and only require minimal clean up and finishing.

Stereolithography or SLA creates prototype part layers through the utilization of a solid-state laser. The 3D CAD data guides the laser as it cuts thru the skin of a container which typically contains liquid photopolymer material.

In LOM, on the other hand, uses a paper sheet with one side laminated with adhesive. The laser cuts the outline on the paper sheet. This process does not involve any chemical reaction which makes it cheaper and enormous parts can be made.

We continue the discussion on how data deduplication has revolutionized how PC backup software works. This article is the second in a series that attempts to explain how various factors define the success of a PC backup. We have already explained Target Vs Source-based Deduplication.

Inline Vs Post-process Deduplication

In target based deduplication, the deduplication engine can either process data for duplicates in real time (i.e. as and when its send to target) or after its been stored in the target storage. The former is called inline deduplication.

The obvious advantages are:

–       Increase in overall efficiency as data is only passed and processed once
–       The processed data is instantaneously available for post storage processes like recovery and replication reducing the RPO and RTO window.

The disadvantages are:

–       Decrease in write throughput
–       Extent of deduplication is less – Only fixed-length block deduplication approach can be use
–       The inline deduplication only processed incoming raw blocks and does not have any knowledge of the files or file-structure. This forces it to use the fixed-length block approach (discussed in details later).
–       The post-process deduplication asynchronously acts on the stored data. And has an exact opposite effect on advantages and disadvantages of the inline deduplication listed above.

File vs Sub-file Level Deduplication

The duplicate removal algorithm can be applied on full file or sub-file levels. Full file level duplicates can be easily eliminated by calculating single checksum of the complete file data and comparing it against existing checksums of already backed up files. It’s simple and fast, but the extent of deduplication is very less, as it does not address the problem of duplicate content found inside different files or data-sets (e.g. emails).

The sub-file level deduplication technique breaks the file into smaller fixed or variable size blocks, and then uses standard hash based algorithm to find similar blocks.

Among the better products PC backup software that use both post-process and sub-file level data deduplication is Druva inSync. Get a free trial today at http://www.druva.com/insync/pc-backup
