Cloud computing solutions provide users with on-demand services. These services are available directly thanks to the industrialization of delivery systems. After you've selected the service you want, you submit your request to a system that processes it directly, without human intervention. This high-level automation delivers a fast, self-service model. Otherwise known as "service on demand" or "as a Service" (*aaS) in the context of infrastructure (IaaS), a platform (PaaS) or software (SaaS).
The biggest difference between the two server environments is scale. If you’re looking to launch as quickly as possible and don’t care about scale, then a VPS server can be a great starting point. However, if you demand a flexible hosting setup and a high level of site performance and storage then it’s worth checking out a cloud hosting environment.
A mere 1-second page load delay impacts your bounce rate, SEO rankings and even your conversion rate. You won't have to worry about any of this when you choose A2 Hosting and our screaming fast SwiftServer platform! Hosting on speed optimized servers with your choice of server location, free SSDs and our up to 20X faster Turbo Servers are all advantages of choosing A2 Hosting!
One of the main benefits of using cloud hosting services is flexible and more cost-efficient scalability in building applications, websites and other services. Because users can scale as needed, they are charged only for the services they use and do not pay for any unused capacity. This payment system makes cloud hosting a relatively inexpensive method of storage.
This approach to centralized administration aids both the service provider and users in defining, delivering, and tracking SLAs automatically on the web. Most cloud hosting services are provided through an easy-to-use, web-based user interface for software, hardware, and service requests, which are instantaneously delivered. Even the software and hardware updates can happen automatically. It is as easy as online shopping!
Few things are better than the confidence you feel when slipping on a perfectly tailored outfit. A knowledgeable seamstress can take average clothing and make it feel custom-made. Cloud servers are the hosting equivalent of your favorite tailor. The best provide top-notch, reliable service at an affordable rate, delivering a product that meets your specific needs.
Some of the best VPS hosts, like the one below, power their plans with cloud networks to take advantage of server clusters boasting high levels of redundancy and availability. The optimized architecture streamlines operations for the hosting provider, who in turn can choose to pass the savings onto customers. Take a look at our recommendation for affordable cloud-powered VPS:

This managed virtualized cloud solution, powered by VMware®, includes the security of dedicated servers along with automatic backups, recovery and snapshots. You also get the support of our virtualization team, including VMware specialists who manage your physical server, virtualization layer and virtual machines so you can get the most out of your solution.
Cloud hosting costs more than a VPS because you are paying for a lot of hardware, complex networking, and the resulting uptime guarantee. With these plans, you pay for what you use, so costs could be unpredictable due to unknown traffic spikes. Think of it as you would your electric bill. Sure, there is plenty of power available for you to use when you need it, but your bill goes up at the end of the month.
Data centers use from 1 to 2 percent of world’s electricity. And only around a quarter of our current energy is renewable - there are still plenty types of conventional power used in order to get electricity. Examples of such ways are coal, oil, gas or nuclear energy. In turn, this means that the more servers there are, the more electricity they use. Because most our energy comes from conventional sources, servers increase our carbon footprint. In fact, a CLEER model simulation (a tool by Lawrence Berkeley National Laboratory and Northwestern University) published in Scientific American reveals an interesting fact. If all US companies would move their spreadsheet, email apps, customer management software and similar programs to the cloud, that would save enough a lot of energy. How much exactly? Enough to fully power the city of Los Angeles!

Interserver offers managed support when you purchase 4 slices or more. You can count on us to help you with security patches, diagnosing of failed services, and help with control panel issues. To take advantage of our support services we highly recommend using a control panel such as cPanel, Plesk, or DirectAdmin. Get additional information on our managed support services.


4 The amount of aggregate outbound bandwidth across all attached network interfaces (PublicNet, ServiceNet, Cloud Networks). The maximum amount of outbound public Internet bandwidth is limited to 50% of the aggregate limit. Inbound traffic is not limited. Host networking is redundant and bandwidth is delivered over two separate bonded interfaces, each able to carry 50% of the aggregate limit. We recommend using multiple Layer 4 connections to maximize throughput.
The common pricing model in cloud hosting is to pay as you go without large upfront costs. Be wary of any plan or hosting company that seems to buck this trend. Inquire about the security of the datacenters that house the servers. One study found that one third of data breaches involved some compromise of physical security. The decentralized nature of cloud hosting makes data security more complicated. Be sure that the network you will be using is compliant with regulations such as PCI DSS and HIPAA. Look for third-party audits to confirm this.

Rather than being hosted on one single instances of a physical server, hosting is delivered on a virtual partition which draws its resource, such as disk space, from an extensive network of underlying physical servers. If one server goes offline it will have no effect on availability, as the virtual servers will continue to pull resource from the remaining network of servers.
