A Beginner's Look At Virtual Private Servers

A BEGINNER'S LOOK AT ERSVIRTUALPRIVA IRTUALPRIVATESE ATESERVERS VIRTU, In this day and age, how we store, process, and deliver our data is always changing. Since it launched in 2001, the Virtual Private Server (VPS) has become increasingly popular. By re-imagining existing technologies, this type of server has revolutionized the way we store and manage data on the web. THE WORKINGS OF A VPS You start with a single machine VPS VPS VPS VPS VPS VPS VPS VPS One machine is used Each virtual server is created for use by a single customer account Although they are run on the same machine, every container has its own software The hosting software is kept separate from all the software running on your virtual server/container to create several virtual servers You select a VPS hosting company HOST BI LL The hosting company You then only have access to your own section (container), but split the costs of the server with the other clients You are assigned a target amount of bandwidth, disk space, RAM and CPU power virtualizes their server The Divides physical server into multiple virtual servers without having to purchase additional hardware Instant Benefits Provides the benefits of dedicated hosting service at a lower cost Offers higher security levels Provides a wide level of control over your hosting (i.e. Allows installing of a wide range of server software) Can provide guaranteed levels of server resources which you do not get with shared hosting (not all VPS systems provide this) Many VPS systems are upgradeable Is available with two primary different levels of support UN- MANAGED FULLY MANAGED Hosting company is responsible for hardware and network support and the virtualization environment, but the client is responsible for installing, configuring and upgrading the operating system and all software. Host manages all hardware, network, virtualization software, operating system and control panel software issues, while client only concerns themselves with installing custom software. This varies from vendor to vendor. THE OTHER TYPES OF SERVERS Shared Hosting Service A web hosting service which houses many web sites simultaneously There are many websites on the same machine, all sharing the same space and the same resources ( The cheapest The potential to have your website impacted by other users on the system is higher on shared hosting services The host usually offers tools to easily install server software without root access hosting option Dedicated Server For this server, a single user occupies all of the resources of a computer ( Most commonly used for websites with higher traffic needs or for heavy data/database processing Tends to be expensive and can have poor support structures (i.e., for example, some vendors only provide unmanaged support for dedicated servers) Generalizations that are not always true to cloud server Definition of what is a cloud server varies greatly: most widely accepted definition is Operates like a dynamic VPS - servers, storage, network bandwidth, etc. can be spun up or spun down on the fly at any time based on demands Additional servers can be added while still running Hardware like RAM or Can be very Tend to charge by Good for handling a wide variance in user traffic CPU is easily changeable expensive the hour of use SOME OF THE MORE POPULAR VPS Virtualizes the Operating System rather than your hardware BUT unable to guarantee server resources; in that sense it is only somewhat better than shared hosting Uses a centralized management system to enable speedy updates, saving up to 75% on server maintenance costs ||Parallels Users do have their own IP, so they are not affected by blacklisted IPs, etc. Optimiced Comouting Makes it possible to run 300% more VPS subscriptions per server Files are easily restored Can be used with Simple user interface RAM is No virtual Resources are shared Windows or Linux shared device support by multiple users Uses the partition in the server to isolate virtual machines The use of dedicated RAM gives an accurate prediction of performance output Microsoft Supports up to 1024 active virtual machines per system Does not support virtual USB or COM ports Hyper-V Every virtual machine requires its own RAM Audio hardware cannot be virtualized Supports up to 1 TB of RAM and offers a minimum of 20 GB of disk space Is now open source software and contained under the General Public Licence, making it free Can support 4095 host processors and up to 512 guest processors Works in several layers called "domains" Has good security isolation Xen Also able to guarantee Lacks hardware support which can affect performance server resources Scales 16 TB of RAM per host and 1 TB of RAM per quest Starter packages begin with at least 50% share of the CPU Is a full virtualization solution for Linux on Each KVM container The major Linux can run a different Linux Os distribution vendors all seem to x86 hardware be standardizing containing virtualization extensions KVM Guarantee server Similar to Xen, except that it operates at the kernel level so it is very AKVM resources better than all other approaches fast A new model for cloud computing Itit openstack" Gives the ability to spin up/spin down servers on demand Can add server Can run virtualization With some additional resources on demand "tuning", can use it to instantly provision VPS servers software on top of it WHAT YOU WANT TO CONSIDER WHEN CHOOSINGA VPS SOLUTION () Are you upgrading from shared hosting? Will the vendor provide the proper migration tools? Almost all shared hosting is managed, and if you are not technical, make sure you go to a managed VPS solution or you will be lost. If you will be starting with shared hosting, but will need to move to VPS soon, will the vendor provide migration tools that will automatically move your hosting data, domains, etc. to the VPS service? Problem with others on a shared hosting platform? How fast do you need your VPS solution? If so, you'll probably want to only consider KVM or Xen solution, which is able to guarantee resources. Other solutions are a lot like shared systems. Can the hosting vendor provide instant provisioning? Or will it take them 12-48 hours to get it up and running? How expandable is the VPS solution? What if you want to add more than one hosting service? If you will need to add more RAM or storage down the road, how difficult is that? Some vendors force you to upgrade while others can add resources on demand. How easy is it for you to manage all of your hosting services? Does the vendor provide a single login to get to the control panel and all the tools to manage your service? Does the vendor allow you to easily upgrade from VPS to dedicated server when you need more power? CONCLUSION In the end, there are many pros and cons to using a VPS - and there are many different virtualized platforms out there, each of which will come with its own pros and cons. Despite this, no matter the type of business you run, there is a type of server out there perfectly suited to your needs. But make sure you consider all the options so you get one that matches your needs, as VPS service offerings are not created equal. Brought to you by: SOURCES
