Dedicated RAM Allocation for VPS Server

There’s nothing like too much in terms of purchasing a dedicated virtual RAM. However, there is such a thing as too little RAM allocation, and it could ruin your site. Most people try to play it safe and purchase more virtual RAM than they require. Doing this is a severe waste of resources; thus, there is a need to anticipate exactly how much virtual RAM your site needs to run efficiently.

Determining the correct amount of RAM you need for your VPS is where the confusion sets in for most people. However, this article helps take care of that problem and quickly determine your virtual RAM resource.

How Important is RAM Space to My VPS Operations?

Have you ever gotten frustrated by the issues your eCommerce site keeps having? Perhaps, it has begun to lag, is terrible slow and selectively available? Well, one of the reasons could be insufficient RAM allocation. Shocking right? Well, that is just how important RAM is to your VPS hosting.

The logical thing to do would be to invest in more virtual RAM space, but how do you know how much to get? Part of it is dependent on what is installed on your server currently and what you would like to install in the future. The volume of traffic your site caters to and how much you expect that number to increase is also a determining factor.

How Much RAM Do I Need for My VPS Hosting?

We picture you staring at an order form for a VPS, confused, and wondering what to focus on. Should it be the disk space, RAM, or CPU? Let’s clear up that confusion. You must realize that your RAM is the most crucial factor for your entire VPS operations.

Now that you know what to tackle first, the next issue becomes just how much RAM you need for your VPS to function optimally. We do not have a clear cut answer to this question. However, we can tell you that your RAM resource depends on a host of factors, which we will discuss below.

To start, there are a couple of questions you must answer to help get the right amount of RAM you need for your VPS.

1. Which Service Do You Hope to Run on the VPS?

Some people may want to run only one service on the virtual server, while others intend to run multiple services. For example, mail server, web server, and database all on one server. Ask yourself which category you fall in.

If you intend to run multiple services on your virtual server, you will need more RAM for your VPS than someone who wants to run just one benefit. Bear in mind that each service you run needs RAM. If your RAM is insufficient, your server begins to lag and swap. That means that less-used parts of your memory are stored on the hard disk. Swapping slows down your VPS processes considerably.

Thus, when getting virtualized RAM, you must get enough to run all your processes. We recommend 2 GB RAM for a web server with little or moderate traffic that has MySQL installed.

2. What Amount of Disk space and CPU Do You Need?

While the RAM is the essential resource for a virtual server, it is necessary to keep other resources in mind. Your server will need space for kernel updates, log files, operating systems, and backups. For disk space, we recommend a minimum of 10 GB; however, you may use it up quite quickly in most cases. Thus, it is best to get as much as 20 GB for your VPS.

Your CPU is another vital VPS resource that helps with computationally intensive functions. For most people, 1 CPU will suffice. However, if it won’t cost much extra, you can add an extra CPU to your VPS, but the difference is often negligible.

3. How Many People Visit My Site?

In determining your Virtual RAM requirement, it is essential to consider how many users visit your site and the traffic your site faces regularly. There are two measurements for site traffic; the number of visits and traffic in bytes.

Traffic in bites refers to the amount of information in bytes transferred between your clients and the virtual server. The traffic in bytes measurement is not as relevant again, so most times, we focus on the number of visitors that flock to your site. Each time someone visits your site, your VPS is tasked with creating a process to cater to the visitors’ requests. That means that you need RAM from your virtual server to carry out the operation.

4. Your Operating System and Content Management Systems in Use

Shocking right? However, regardless of whether you use Linux OS or Windows OS, you will need to pay attention to critical factors. The key factors to consider as regards your OS the version and year. The version and year of OS affect your RAM because there is a stated baseline memory they’ll require.

You must also take into consideration CMS you use. If you use WordPress, Drupal, Joomla, and the likes, you will need to get a VPS with more RAM allocation. Don’t forget to keep in mind the number of plugins and modules you’ve installed.

What are the VPS RAM Requirements for Some Common Open Source Applications?

We have already said that your VPS RAM requirement, in part, is determined by the number of software and applications you have installed on your server. A simple rule of thumb is that the more software and memory-intensive apps you have installed, the more RAM you need for your VPS to run smoothly. One way to ensure you have enough virtual RAM is by adding the RAM requirement for your app and software. Be sure to leave a little extra for wriggle.

However, most VPS hosting providers allow you to upscale your RAM allocation, so you may not need to rack your brain trying to add up. Let’s consider how much VPS RAM you need for the popular open-source software.

❖ cPanel

cPanel is a popular website and server management tool used by site owners. It provides you with access to your server environment. cPanel allows you to tweak and customize your server space. Thus, for most site owners, it is an essential open-source resource.

If you are looking to customize and manage your website with this server and website management tool on CentOS 6, you will require at least 786 MB of RAM. However, you will need a minimum of 1 GB RAM to install cPanel on CentOS 7.

We advise that you get a VPS with at least 1 GB of RAM to run this software. 1 GB will be sufficient to run both WHM and cPanel. However, if you can, get a VPS with 2 GB worth of RAM.

❖ Webmin and Virtualmin

Webmin and Virtualmin are great websites and server management tools you can use in place of cPanel. They are free cost-effective alternatives to cPanel. With the Virtualmin plugin, you can easily manage various servers.

We recommend getting a VPS with at least 1 GB RAM and a minimum of 2 GB swap space to install these tools and use them without hassles. If you use a CentOS 8, you will need at least 2 GB RAM and a recommendation to use a minimum of 4 GB swap space.

❖ WordPress

Even though WordPress is a popular content management system, its RAM requirements have not been published officially. Although you can efficiently run a small site with RAM as little as 256 GB, you will need more to run WordPress comfortably.

If you want to run WordPress on your server, you will need at least 512 GB worth of RAM space to guarantee premium site performance. However, you will require more RAM space if you intend to use lots of plugins like shortcodes and page builders. Since getting a VPS hosting plan is not as expensive as it used to be, we advise that you get one with at least 1 GB.

Note that this RAM requirement is for only one site. So if you intend to host more than one site, you will need to double the virtual RAM requirement.

❖ Other Content Management Systems

Asides from the more popular WordPress, there are other CMS. They include Joomla and Drupal. You will need a VPS with at least 786 GB to install and run these CMS tools on your server. However, as always, we advise that you give room for a little wriggle when choosing the virtual RAM. Thus, it would be best if you went for a VPS with a minimum of 1 GB.

❖ NextCloud

NextCloud is a file storage or, if you like, a cloud storage tool. It is a well-known alternative to Google Drive and Dropbox. With it, you can host files on your virtual server; all you need do is employ the graphic user interface.

You can store calendars, contacts, files, and much more on your cloud and even synchronize them across all your connected devices. You can also share files and data with others using NextCloud.

The official manual says you require at least 128 MB worth of RAM to run this tool. We, however, advise that you use a VPS with at least 512 MB worth of room. Our recommendation is also based on the fact that NextCloud uses MariaDB/MySQL database. Recall that the MySQL manual recommends at least 512 MB RAM. Thus a VPS with 512 MB RAM will offer you premium performance even with NextCloud installed.

What Happens When I Don’t Have Enough RAM for My Server?

We have already established that RAM is the most crucial resource for your virtual server. Now let’s understand what you stand to face with insufficient virtual RAM. Ever gone on a website that took too long to load? Yup that is exactly what will happen to your site if you try hosting it on a VPS with too little RAM allocated.

The sad thing is that this RAM problem will affect your site negatively. That is because most visitors do not have the patience to wait more than 30 seconds for your site to load. So you see, the lags and slow loading speed causes you to lose visitors and potential sale conversions.

To beat this and stay on top of your game, you need a VPS that offers you the right amount of RAM you need. As a bonus, we have provided you with two such VPS.
