In a shared space, like VPS, it’s hard to imagine how multiple servers operate independently. And yet this is completely possible thanks to virtualization software, known as the hypervisor. This software segments a single physical server into multiple virtual servers and keeps each of them separated from the rest. As a result, you now have access to what is, called a Virtual Machine (VM). Each of these virtual machines runs a complete OS and is restricted to a portion of the physical server. While multiple tenants share VMs on the same server, they are restricted from interacting with each other. This allows for perfect privacy, even with multiple users.
I have used shared hosting for over 7 years before I finally decided to upgrade to a VPS server. When I was using shared hosting, I had so many problems with malware, slow loading time, brute force attacks and so many other issues. Now, my life is so much easier with VPS. What amazes me the most is the support team; they simply exceed my expectations and they are ALWAYS available to answer my questions.
While VPS hosting allows you to choose and configure your operating system and server applications, dedicated hosting goes one step further. It doesn’t only let you configure the software but also the hardware, as the entire server is yours and no one has any say in the setup. You can also run a dedicated server on-site (for instance, in your office), however you lose the support of a professional hosting team in that case.
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!
A virtual private server (VPS) is a cost-effective way for a small business to gain more flexibility and efficiency than is offered with shared hosting without the expense associated with running a dedicated server. Most small businesses also don’t need all the power of a dedicated server, so VPS provides a good in-between option when you outgrow your shared hosting. Get the power and flexibility of your own server without the cost and complexity of managing outsourced hardware.

The most obvious and popular reason for a VPS is to run a single website, or multiple websites. However, you can use them for pretty much anything that requires access to the internet – such as a web application like Nextcloud to run your own Dropbox alternative – or to create your own virtual private network to better secure the internet connection of your PCs and mobile devices.

With cloud hosting, you don’t use a single server but rather a cluster that runs in the cloud. Each server in the cluster stores an up-to-date copy of your website. When one of the servers is too busy, the cluster automatically redirects the traffic to a less one. As a result, cloud hosting comes with no downtime, as there’s always a server in the cluster that can serve the requests of your website visitors.
Yes, VPS is a powerful and versatile type of hosting that many companies will find meets their needs. If you’re already hosting in a different type of environment, you may be wondering whether it’s worthwhile to migrate to VPS. This is an important discussion to have with each prospective hosting provider in order to understand how they handle migrations, what would be required from you, how long it might take, and any costs associated.

Do you plan to sell products or services? If so, you'll want to invest in a web hosting service that offers Secure Sockets Layer (SSL). An SSL connection encrypts the financial information that shuttles between users' web browsers and your website, thus safeguarding the transmission of the purchasing information. Some hosting companies include a free SSL certificate when you sign up for a web hosting plan, while others charge close to $100. You can save some money by shopping around for services that offer the cheaper SSL plans.
VPS, on the other hand, is an isolated playground specifically for you. You will be able to install and use any professional software you need. It also provides more opportunities for caching the content. Imagine that you implement caching tools to provide your users with better experience and reduce the loading time of your website. Caching means that the part of requests to your website will be processed using RAM instead of a hard drive. Eventually, RAM will be filled with these requests. Since VPS deals offer more RAM then shared packages, you will get better performance using caching.
Types of VPN offered: OpenVPN, Wireguard, StealthVPN, OpenWeb, PPTP, L2TP/IPSec, SSTP, AnyConnect
Recently, we've added more-formal uptime monitoring to our review process, and the results show that most web hosts do an excellent job of keeping sites up and running. Even if they get everything else right, sites with uptime problems aren't eligible for high scores. All services suffer ups and downs, sometimes for reasons beyond their control. Those sites that fail to address the problem in a timely manner are penalized accordingly.
In fact, most webhosts will offer the same LAMP web server stack software on their managed VPS plans as their shared hosting accounts. The main difference is the level of dedicated system resource allocation, such as RAM, CPU cores, bandwidth, or storage options. VPS plans also offer far more configuration options for web server customization with the command line than shared Linux or Windows hosting plans.
While there are more affordable VPS services out there, A2 is a worthy consideration because of its excellent support. It is a company that takes a remarkable care of non-clients goes to great extents for its trusted users.

Any proxy server will be fine for avoiding blocks, even a free one (just remember that if you want to protect your privacy, a free proxy is as helpful as a tinfoil hat). For more advanced proxy usage you will need to have a server with root access (a VPS or a dedicated server). A proxy server does not require many resources, that’s why you can save money and set up a proxy on a VPS.

It can take hours to build a web server with support for all of the programming languages and latest web standards. Managed VPS plans bring all of the software required for programming and web development (DevOps) into a PaaS product that is available instantly. From this, there are also many differences in LAMP stack configurations between webhosts. Buying a Managed WordPress VPS hosting plan with pre-configured Nginx and Varnish Cache installation can save thousands of dollars in web development costs for small businesses.

With Cloud VPS, if a parent server has 64 processing cores, it can host up to 64 instances. Each instance is allocated its own bandwidth and storage, so your performance won’t be affected by other companies on the server in the way it might with shared hosting. You also get more bandwidth and storage since the hosting company is limited on the number of instances they can create on each parent server.

The current trend in Linux web server OS distributions is for extremely lightweight installation requirements and integration with containers for elastic scaling of big data applications. Rancher and CoreOS both work with Docker and Kubernetes as well as other cloud orchestration platforms like OpenStack, CloudStack, CloudFoundry, OpenShift, Mesosphere, etc. Lightweight OS installations increase the number of virtual machines that can be created on data center hardware, leading to greater efficiency in production environments.

One of the biggest pitfalls of VPS hosting is having to manage your entire server environment by yourself. If your virtual server is not configured and maintained well, you may face serious security risks and performance loss. Managed VPS hosting services have appeared on the market as a viable solution to this problem. You can think of it as an enhanced alternative of VPS hosting, that comes with full technical support.

Quick review: AltusHost is a well-known premium hosting provider based in Netherlands. The company provides rock-solid customer support and offer three different server locations in Europe (Bulgaria, Netherlands, and Sweeden). We think AltusHost may be the right call for small businesses and individual bloggers who want a reliable EU-based hosting solution.
Managing servers is time-consuming and technically demanding. It can be expensive to staff an entire team dedicated to maintaining hardware updates, monitoring security, and generally keeping things online. With this in mind, some of the leading hosts offer IT expertise to manage the infrastructure for you. It’ll cost a bit more but, more than likely, managed support will also save you a priceless number of headaches. InMotion Hosting’s service is top-of-the-line when it comes to managed VPS hosting.

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!

Dedicated hosting is true to its name. It includes a fully-dedicated host server where 100% of resources are dedicated to your site. VPS, on the other hand, has a dedicated amount of resources allocated to your site from a shared server, essentially giving you a piece of a larger whole. When you have a dedicated host, the entire host is yours to utilize.


With a standard shared hosting plan, you’re at the whims of other webmasters who share the same server. Some companies put hundreds of websites on the same physical server. If one of those sites experiences significant growth or gets a sudden influx of traffic, your site’s performance will suffer. There are only so many resources to go around. When one site needs more resources, it’ll hog them and cause issues with the other sites.
It's also possible to select different PHP "execution modes" for each site at Virtualmin > Server Configuration > Website Options - I recommend FPM because it's significantly faster and uses less memory. I've found that the default settings sometimes result in excessive memory usage, which can be avoided by adding the following settings to Virtualmin > Services > PHP-FPM Configuration, which limit the lifetime of processes if a site has a memory leak:

For managing the content of individual sites, I recommend using a well-supported Content Management System (CMS) such as WordPress or Drupal. Even very basic sites need to be updated regularly and a content management system makes this much easier, as well as giving you access to themes and plugins that add useful functions such as search forms, contact forms with spam protection, image galleries, event calendars, online shops and so on. Proprietary systems or “website builders” generally have more limited features and can be very difficult to update or move to a new host.
