Cloud Hosting FAQs

Q:  What is a virtual server and a virtual dedicated server?

A:  A virtual server, also called a vServer or a virtual machine (VM), is a software implementation of a server (i.e. a computer) that executes programs like a physical server. Virtual servers are separated into two categories based on if they share the same operating system with other virtual servers. Virtual servers created by software such as Virtuozzo share the same operating system and are separated by containers. These container-ized type of virtual servers are called Virtual Private Servers ( VPS ). Virtual servers created by virtualization hypervisors such as KVM, VMware, Hyper-V and Xen do not share the same operating system and are called Virtual Dedicated Servers (VDS). All vServer Center's vServers are Virtual Dedicated Servers. Each Virtual Dedicated Server has its own dedicated operating system and maintains the same functionality as traditional physical computers. Virtual Dedicated Server owners have "root" (for UNIX operating systems) access and control or "administrative" (for Window operating systems) access and control of their servers. Any software applications can be installed by Virtual Dedicated Server owners remotely at anytime.

Q:  What is a Cloud server?

A:   A Cloud Server is a virtual dedicated server that is served by a computing resource pool (aka Cloud) consists of network switches, data storage systems, physical computer servers, and cloud computing software. A physical dedicated server or a virtual dedicated server on a single physical computer lacks redundancy and scalability while each of vServer Center's cloud servers offers extremely high redundancy and scalability: redundant powers, redundant network uplinks, redundant enterprise class data storage systems and data disks, redundant high end physical computer servers. For some Cloud Servers, you can upgrade a cloud server's computing resources such as CPU, RAM and disk space while it is running. If you are familiar with dedicated servers, check out our Cloud Server vs Dedicated Server comparison chart and see why cloud servers are rapidly replacing dedicated servers .

Q:  What are the advantages of hosting servers or software applications on vServer Center's Cloud Computing server farms?

A:  Servers and software applications hosted on vServer Center's Cloud Computing server farms benefit from high levels of redundancy, scalability and performance. vServer Center Cloud Computing server farms provide:

  1. Redundant electric power: All hardware systems receive electric power feeds from dual backup UPS (Uninterruptible Power Supply) systems, dual power generators, and separate electrical utility feeds from our power utility company. Our server farms are not just on N+1 power generators which are on a single ATS. We are on separate generators on separate ATSes which are on separate power grids.
  2. Redundant high end physical computers: In the rare event that any hardware server should fail, the servers and software applications are instantly and automatically switched to redundant servers.
  3. Redundant Enterprise storage systems: We use only the best of class Enterprise Storage Systems for reliability, performance and scalability. Many cloud server providers use commodity hardware similar to your home PCs to store and serve your data. Such commodity hardware lacks in performance and reliability.
  4. Redundant data Protections: vServer Center deploys two hot spare disks in addition to dual parity disks in all RAID groups. All SAN storage volumes are Snap Mirrored to another Enterprise SAN storage system;
  5. Redundant Backbone bandwidth: vServer Center maintains redundant upstream backbone connections that consist of multi-homed (BGP4) direct fiber connections up to 10Gbps into four different Tier 1 Internet backbone providers.

Q:  KVM, VMware, Hyper-V, or Xen Cloud Servers, which platform should I choose?

A:  If you are already familiar with a virtualization platform, you can choose the platform that you are familiar with. If you are not familiar with any virtualization platform, you choose Hyper-V Cloud Servers for better performance if your server operating system is Window Servers. You choose VMware Cloud Servers if you need more flexibilities and more features. You choose KVM Cloud Servers for lower cost while maintaining a high level of cloud server performance.

Q:  For each virtualization platform you offer four different plans: Standard, Silver, Gold, and SuperNova, which plan should I choose?

A:  You should first look at your server's performance needs. Do you need 1 CPU core, 2 CPU cores, or 4 CPU cores? Websites with heavy script use or database query may require more CPU cores. You also need to consider RAM requirement of your software applications, and disk space requirements of all the data you have now and what is needed in the near future.

Q:  How many IPs do I get for a cloud server?

A:  You get one IP for each cloud server. You can order additional IP blocks on our Add On page. . You can have multiple IP blocks on one cloud server. We have Zero Tolerance for Spam! We do not support spam of any kind.

Q:  How much bandwidth do I get for a cloud server?

A:  The bandwidth you get is based on the service plan you selected. The bandwidth amount is specified in your service details. We offer unmetered bandwidth so you won't get a surprise bandwidth bill. Here is how you convert port size measured in mbps to total monthly data transfer measured in GB:

1mbps = 1 megabit per second
= 60 megabits per minutes (1 minutes = 60 seconds)
= 3600 megabits per hour (1 hour = 60 minutes)
= 86400 megabits per day (1 day = 24 hours)
= 2592000 megabits per month (1 month = 30 days)
= 324000 megabytes per month (1 byte = 8 bits)
= 324 gegabytes per month (1 gegabyte = 1000 megabytes roughly)
= 324 GBs per month ( GB = GegaByte )

For example 10mbps bandwidth may get you 3240 GBs of Monthly Data Transfer each month; A typical text based webpage is about 10,000 bytes. So 1GB is about 100,000 pageviews. 3240 GBs is about 324 millions pageviews per month. You get less pageviews if your website is heavy in images or videos.

Q:  Do you offer any High Availability (HA) cloud servers?

A:  Our VMware cloud servers come with HA. You do not need to pay anything extra for HA. If a physical computer fails, your VMware cloud servers will be automatically switched to other live physical computers;
