It seems you can't watch TV, listen to the radio or surf the internet without hearing about the "Cloud". Cloud has become such a buzzword that it has almost lost any meaning at all. We put the meaning back into Cloud. To A2 Hosting, Cloud Hosting means a high powered, developer friendly, reliable and scalable hosting solution. That's exactly the level of Cloud Hosting service you'll get from A2 Hosting.

Varnish Cache is a powerful web application accelerator that can speed up a website by up to 1000 percent. Varnish is typically used for content heavy dynamic websites. It is used by high-profile, high-traffic websites including Wikipedia, online newspaper sites such as The New York Times, The Guardian, The Hindu, Corriere della Sera, social media and content sites such as Facebook, Twitter, Vimeo, and Tumblr. Of the Top 10K sites in the web, around a tenth use this software.
When a website is hosted on shared hosting, the website is placed on the same server as many other sites, ranging from a few to hundreds. Typically in this setup, all domains share resources, such as RAM and CPU from the same server. Cloud hosting, on the other hand, offers nearly unlimited ability to handle high traffic spikes. On Cloud, your website is hosted not only on one but on several servers connected to work as one. Your websites don’t depend on only one Server– even if one server is inaccessible, the Data is retrieved and processed by the other available servers with no downtime.
Back in the day, it was either shared or dedicated hosting. Many of the companies dependant on superior load times and in need of a lot of disk space have gone with dedicated hosting. It became their primary option. When cloud technologies started to develop, some people switched to cloud server hosting instead. Plenty of companies use cloud hosting without experiencing many problems. Dips in performance and unexpected downtimes, both fairly common in shared hosting, can be prevented here.
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!
Here’s an example of a SysGen hybrid model. As you can see, the client has an onsite server with local backup storage. Employees access their desktops, applications, files, printers, and email from the office using the local network. At the same time, data is backed up for redundancy to a cloud-based solution, and email is entirely in the cloud with Hosted Microsoft Exchange. The cloud configuration also gives employees anywhere access to their desktops, applications, files, printers, and email. (Click the photo to enlarge it).

Let's say that you, for example, use a regular shared server instead of cloud hosting. One physical server has all of your data and them, just like that, it's down or even completely wiped out. Issues in one shared server account can cause troubles to the other sites on the same physical server. Usually, that's downtimes and file loss! You only use one server for shared hosting. When someone hacks it - it’s bad news. 

The most affordable way to run a virtual private server is available here. You can save hundreds of dollars per month when you compare the low cost of VPS with a dedicated server. Or even save thousands of dollars of upfront hardware costs and countless hours of provisioning and maintaining. VPS is the ultimate solution for a cost effective and balanced solution to deploying your applications on the world wide web.

“Guaranteed uptime” is one of the most common buzzwords in the business. Most (if not all) hosting providers offer uptimes of 99.9% and higher. Some cloud hosting companies, like A2 hosting, for example, genuinely deliver on their promises. Yet still, it's important to know how downtimes work.  This convenient chart shows, how often your website can still go down with the provider’s “guaranteed uptime”.
A top consideration in choosing a VPS plan is whether you want the service to be managed or unmanaged. Unmanaged plans are less expensive, but they put the burden of server management on your shoulders. With a managed plan, experts take care of many security and performance concerns. In addition, when you choose the memory, CPU power, and hard drive capacity of your virtual machine, also inquire about the quality and specifics of the physical host it will run on to be sure that the physical host has the power to meet the demands of your virtual machine. Finally, check on the backup plan and redundancy for recovery from any disasters or malfunctions.
From an IT perspective, the flexibility of rapid solution deployment for an evolving business need is critical both to the client and the service provider. In an established environment with a long history of IT implementations, it is not easy to deploy a new solution within weeks without affecting the existing infrastructure or the available funding in a big way. Cloud hosting provides the options and advantages of quicker solution deployment and lower cost of implementation and operations.
If you're looking for a real-time example of cloud hosting, what better example can someone give other than Google itself? The king of search engines has got its resources spread over hundreds of servers on the cloud, no wonder you've never seen Google.com facing any downtimes over past decade or so (I don't remember seeing it down – planned maintenance of services like AdSense and AdWords are a different affair altogether!)
Customization with cloud hosting expands to include the possibility to tweak network architecture, firewalls, load balancing, and IP addresses. However, the need to distribute functioning across many servers may leave less control over some hosting settings. Both Windows and Linux clouds are readily available, so you will get your choice of OS. Because a cloud environment is more complex, it may require more technical expertise to configure, especially to gain the full advantages of the cloud network.

You get to benefit from an economy of scale, meaning you sharing hardware with other businesses but only pay for the amount of compute and storage capacity that you use. If you need to increase your usage, you can do so through a dashboard. You have unlimited flexibility to increase or decrease your resources and can change server specifications with the demands of your business.
The rapidly expanding cloud hosting industry is expected to grow nearly 20% this year to almost $250 billion in worldwide revenue, fueled largely by the proliferation of data in Internet-of-Things devices, artificial intelligence, and Software-as-a-Service business applications. Nearly 40% of small and medium businesses utilize some form of cloud hosting, which provides operational agility in the forms of improved collaboration, the ability to work remotely, better control of documents, and a reduced carbon footprint.
VPS hosting assures a fixed level of performance because a guaranteed level of system resources is dedicated to your virtual server. However, high demand by your server or another virtual server on the same physical host may impact performance if you both need the extra resources at the same time, or if your server needs more than the physical host can provide.
Cloud server hosting offers the advantages of increased accessibility and reliability, seamless scalability and potential cost savings, as customers are freed from having to invest in on-premises servers and hardware, and they pay only for the resources they consume.  On the other hand, security and lack of access and full control are potential concerns with cloud server hosting.
Given the massive demand for cloud storage and computing, hosting providers are clamoring to offer the best services for the best prices. Competition is fierce, which bodes well for those shopping around for the best solution. The top providers, including our four most recommended options below, shine at offering seven key attributes: reliability, availability, scalability, security, quality, strong service-level agreements, and responsive support.

Cloud computing offers users a level of hardware abstraction that means they don't have to worry about all the operational aspects of a datacentre. Hardware is provided and maintained by OVH. As a user, you don't need to deal with stock problems, parts that need replacing or the fluctuating cost of hardware. Forget about infrastructure management and concentrate on developing your business while OVH will take care of the rest.
One of the many benefits of cloud hosting is the fact that users don’t have to manage their own hardware. We monitor our data centers round-the-clock to ensure 100% server uptime and functionality. Also, because cloud hosting involves pooling resources on multiple virtual/physical servers, you’ll enjoy added security and resilience. In addition, customers can expect:
Cloud hosting provides significant capital and operational savings to organizations because they don't have to spend a lot on the initial upfront capital cost associated with owning and managing data centers. IT also has the ability to scale more efficiently, using and paying only for the resources they need. In addition, long-term data retention becomes a more simplified process, eliminating the costly management of disks and tape systems.

Because Cloud VPS is an unmanaged VPS, it requires your own maintenance and setup. We highly suggest this product to those already comfortable with Linux and the command line. Not sure if this is what you need or worried about missing a control panel? Start a conversation with one of our Linux hosting experts and they'll point you in the right direction.

Cloud hosting's use of multiple servers gives it certain advantages over traditional hosting. For example, if your website experiences a sudden traffic spike, it can pull resources from another server to prevent slow page loads or, worse, the site going down. In addition, cloud hosting makes it incredibly simple for your to scale resources up or down, as needed.
The tech giant IBM also points to the great scalability of cloud hosting. As the technology progresses, servers become more efficient, using less energy to handle the same number of tasks. Many companies still use old and inefficient servers. They often sit idle, use energy, are technologically less advanced and have weak cooling systems. Instead of keeping the same dedicated servers or upgrading them, many companies would strongly benefit from moving to cloud hosting.
