virtual machines - Cloud Hosting Provides High Quality at Low Costs
1. Cloud Hosting Provides High Quality at Low Costs
For start-up companies who need reliable server options at affordable costs, cloud hosting may
be the way to go. Cloud hosting refers to many individual servers which are connected to form a
cloud. Traditional web hosting relies on dedicated servers, which means that servers are owned
and operated by one site only. Cloud hosting is kind of like a time share for websites. Many sites
are pooling their resources and in return they get access to many servers. In order to connect all
these servers into a cloud, software, called a hypervisor, is installed on each physical server to
control the virtual machines. Typical software includes VMware or Hyper-v.
Through the use of many virtual servers resources don’t have to rely on a single dedicated server,
making the achievement of a load balancing much more cost effective. Rather than having to
purchase two or more physical servers in a cluster, people who rely on cloud computing don’t
need more than one servers. Also, for those who chose dedicated, or physical, servers, it is
necessary to implement an operating system that supports clustering or load balancing. Users of
virtual machines (VMs) can use any OS they choose, as there are both linux cloud servers and
window cloud servers. VMs are easily upgraded, whereas dedicated servers require shutting
down the system, installing costly equipment, and rebooting.
Cloud hosting offers practically unlimited resources, since the network of servers is infinitely
expandable. Growing companies cannot predict at the start of their hosting needs how many
upgrades and space they will eventually need.With the use of so many virtual machines, sites
don’t have to experience downtime, because if one physical server is down, resources are still
available elsewhere. Traditional hosting options come with many limitations. Server space and
bandwith are generally capped. However, payment through cloud hosting companies generally
offer pay as you go plans, meaning you pay for the amount of bandwidth you actually consumer.
With traditional hosting companies it is necessary to reserve a large amount of bandwidth space
to ensure that your site is never down, though much of it goes unused for the majority of the
time.
Some cloud serving companies also offer pre-configured virtual machines which are able to host
one or many websites. These pre-configured VMs come with CentOS, Apache, MySQL, and
PHP. Many other options exist depending on the specific needs of your company. For example,
there are database options, email hosting, and both Windows and Linux options.
