Powering 28% of the internet, WordPress provides the backend interface for more than 60 million bloggers, entrepreneurs, developers, and enterprise businesses. Given the platform’s wide applications, cloud hosting is a perfect fit for highly trafficked, in-demand websites and online stores. InMotion Hosting, our favorite option for all things WordPress, understandably outperforms competitors in terms of optimized infrastructure, superior management, and ultimate usability:
“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”.
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.
Due to the volume of transfer requests, you can expect a full transfer to be completed anywhere from 10-14 days, experiencing little to no downtime during the migration. If you are looking for an expedited move (for example, your site has been down for days and you need to get it moved quickly), you can purchase Managed Hosting for $40 per hour and they will help take care of the transfer process for you in a 1-2 day window. Launch Assist (2 hours with our Managed Hosting team) comes included free as a part of all 12 month VPS-2000HA-S plans and for all term lengths for VPS-3000HA-S plans.
Our Quick Start Cloud means no confusing price guides and instructions to sift through just to get started. Just design your perfect Cloud and easily re-size your account as resource needs fluctuate. Our ultra-reliable service comes backed by our 99.9% Uptime Commitment. Don't settle for merely a top Cloud VPS Hosting provider; choose A2 Hosting for the Best Cloud VPS Hosting service.
Cloud hosting, on the other hand, tackles the increase differently. Under the cloud environment, the website is hosted on a pool of unified computing resources. This simply means that if one server is reaching its optimum level, then a second server is ready to function. Similarly, if a server fails, the website will still be running as other servers will continue to serve the incoming traffic.
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.
Virtual Private Servers have long been recognized as a way for businesses to reduce IT costs and increase operational efficiency. By isolating applications and programs within one virtual server that’s set aside solely for you, VPS provides high levels of privacy, security and control. But while VPS delivers cost savings on hardware and offers the flexibility to run multiple operating systems or sets of programs on individual servers at the same time, it doesn't scale well.
Our VPS Hosting plans all come with a high availability feature that essentially takes your VPS container, and empowers it with a cloud infrastructure. How does this work? We put a premium on your server's uptime, so we created an infrastructure of redundant hardware clusters that provides your partition with real-time redundancy. If for some reason there is an error on your server, there is another server in the cluster with that backup information ready to spin up. We utilize Virtuozzo, a virtualization solution built on top of OpenVZ.

Enterprise-level, infrastructure-as-a-service cloud hosting from the likes of Amazon Web Services, Microsoft Azure, and Rackspace are also available. Though these are technically cloud hosting services, they are not what's highlighted here. For more on that flavor of expansive (and potentially more expensive!) cloud hosting, please visit our story about the best infrastructure-as-a-service solutions.

Traditional hosting, especially shared hosting, has its drawbacks though. Because the resources of a single server are shared among a number of different websites, spikes in traffic to those websites can mean decreased performance for your own. Security breaches and other performance issues on other sites make take yours down as well. And there’s a single point of failure. If the server itself experiences technical problems, everyone hosted on that server will be affected.
While shared, VPS, and dedicated server hosting packages rely on one physical server at a time, cloud hosting enables an unlimited number of servers to act as a unified system. With so many resources at your disposal, cloud hosting introduces a greater level of scalability, availability, and performance. The added flexibility of adding or removing resources means many hosting providers bill customers monthly for exactly the resources used.
Cloud hosting refers primarily to the use of virtual hardware, network, storage and composite solutions from a cloud vendor. It is enabled through virtualization, whereby the entire computing capacity of an infrastructure or data center is distributed and delivered to multiple users simultaneously. The user uses underlying infrastructure to host its own applications, services and data. For example, a physical server can be virtualized and consolidated to host several cloud servers, all sharing the processor, memory, storage, network and other resources.
