VPS installation on SSD storage is much faster than HDD, where managed platforms offer a pre-installed partition available instantly after sign-up for a new hosting account and some "bare metal" partitions take longer to create. Unmanaged plans usually require the customer to install the operating system and web server stack software on a VPS plan personally. Cloud VPS plans offer snapshot services like Bitnami that can speed up web server installation and CMS application deployment considerably. Beginners will prefer managed VPS plans with CentOS and cPanel for a near identical user experience for multi-domain management as on shared Linux hosting plans.
There are a few downsides to shared hosting, though, mostly because you’re sharing. For instance, if someone else on your shared server has a huge spike in traffic, that could affect your website’s performance. However, if you’re just getting your website off the ground and don’t have huge traffic volume, shared hosting is a great way to get online!
Website owners with misconfigured CMS scripts or out of date security versions of code risk MySQL injections particularly that can lead to the theft of an entire database. VPS admin login panels, cPanel logins, FTP connection routes, and email servers running on Apache are all common attack vectors for script bots which are programmed to target common URL structures on domains.
Your A2 Hosting account comes pre-configured with PHP accelerator OPcache. External tests have shown OPcache offers up to 50% faster PHP processing! While some users prefer accelerators like eAccelerator or xCache, we've found the largest performance boost with OPcache. OPcache is available by default with PHP 5.5, while APC is available on previous PHP versions.
The web hosting company will also provide regular web server software, installed programming language extensions, & firewall upgrades. Managed VPS plans running Windows normally include the use of Plesk for administration of domains and web server settings, while VPS plans running Ubuntu, Debian, Slackware, etc. can be administered using Webmin or Virtualmin under a free open source license.
Proxy literally means “a representative”. It works as an intermediary between your device and the rest of the Internet. When your device sends a request, a proxy intercepts it and checks whether it has requested data in the cache. If yes, it returns the cached version of data without connecting to the requested resource. If not, a proxy server passes your request further but changes your IP to its own. Because of the fact that proxy hides an endpoint device’s IP addresses, it is often confused with a VPN. However, apart from the IP hiding, a VPN and a proxy server are used for different purposes.
VPS stands for Virtual Private Server and refers to a private, emulated dedicated hosting environment created through virtualization on a host (a computer or other device connected to other computers or devices via a network), server (called the “parent server”), or cluster of servers. It acts like a physical server but, in reality, it’s a piece of software that’s emulating dedicated hardware.
Thanks to a hypervisor, a guest OS does not ‘know’ about other virtual machines on a bare-metal server. Like that frog who lives in the well thinking he is in the ocean, a virtual machine ‘believes’ that it is a physical server. In this case, theuser can have root access to a VPS and control its software. Additionally, if we decide to upgrade something or change a physical machine altogether, we do not need to make changes in a guest OS. Let’s get a closer look at advantages of VPS hosting.

As you can see, a VPS can be the perfect middle ground for many – enough flexibility and resources for those who need more access or control than on a shared server but without the cost of a dedicated server. If you need root access, you can’t get that on a shared server, but you can get it on a VPS. If your site experiences unpredictable swings memory usage, and your host provides it, then the presence of burstable memory will be attractive. And, if you’re a fan of customization, then the fact that you can customize server-level software such as PHP, MySQL, and Apache will perk your interest. In short, choosing a VPS will allow you to have many of the same characteristics of a dedicated server but in a more affordable and manageable package.
