How to create a cloud virtual server

What can be hosted on a virtual server?

A virtual server can host almost anything! This includes games, software applications, websites, and even academic papers. You can host very large websites on a virtual server that has a very low impact on your physical resources. You can also host smaller websites such as blog posts, video content, and pictures. You can also use a virtual server for hosting email accounts, social media, and other resources that do not require the server to be located in your own physical location.

How to create a cloud virtual server

Getting started with cloud virtual servers is easy. Every cloud host provides you with a bunch of tools to help you better manage your server. The best cloud hosting service lets you create as many virtual servers as you need and move them anywhere in the world without having to install any additional software. You can set up a server in the cloud and access it through the internet. Or, you can set up a virtual server in the cloud and have internet access on the same device as your laptop or computer.

What are the benefits of creating a cloud virtual server?

  • No additional hardware costs - You pay only for the hardware that's needed to run the server.
  • No operating system or software requirements - Your server runs exactly as if it were running on your own computer.
  • No internet connection required - Your server is located only as far as the internet allows, and all communications occur within that distance.
  • No security risks - Since all communication occurs within the cloud, there are no potential risks of interception or data theft.
  • No need for a dedicated server - You can set up a cloud virtual server on a VPS, dedicated server, or on a virtual machine.
  • No need for networking - Your server is connected to the internet but cloud virtual server uses a combination of software and internet connection to communicate with other computers in the network.

What are the challenges in creating a cloud virtual server?

  • Time - In order to setup and manage a cloud virtual server, you will need to spend some time looking at the data transfer and firewall issues. Generally, this is not a time-consuming task. However, you will likely spend time dealing with other issues such as server management, securing your server, and monitoring the server performance.
  • Data transfer - When data transfer is involved, this is called scalability, and it is a key factor in cloud virtual server. You will want to choose a cloud hosting service with the ability to handle large amounts of data. This is important because if the data rate is low, then the server will be overwhelmed and performance will be very poor.

Top 3 best tools for hosting websites on Cloud Virtual Servers

Vultr - Probably the most popular cloud hosting service, Vultr offers a wide range of services from which you can select to create a virtual server. You can also use Vultr to launch an auto-scaling cloud hosting service that will automatically scale the number of server instances as needed to handle spikes in traffic. The downside to using cloud hosting services is that you need to purchase the entire service upfront and then have to pay for it every month.

Google Cloud - Google Cloud also offers a wide range of services that you can use to create a cloud virtual server. However, whereas AWS requires you to purchase a subscription upfront, Google Cloud is free to use for the duration of the contract.

Rackspace - Rackspace is another cloud hosting service that you can use to launch a cloud virtual server. However, unlike the other two services, Rackspace does not offer auto-scaling. This is a big downside to using the service.

Hosting websites on a cloud virtual server can help you save some money since you won’t have to spend money on hardware and software that you don’t need when you host the website on the server. Additionally, the server is not directly connected to the internet and therefore there are no potential risks of hackers or security breaches. However, the biggest advantage of hosting a website on a cloud virtual server is that you can scale the server up or down in size as needed to handle spikes in traffic without buying a new server. In short, if you are hosting a website that does not require a lot of traffic, a cloud virtual server can be a great option. However, for high traffic websites that require a strong online presence, a dedicated server is the better option.

How to enable swap on a cloud Linux server

When a server runs out of memory, it can cause various issues such as crashing applications, slow performance, or even system failures. One solution to this problem is to enable a swap file. A swap file is a space on the server's hard drive that is allocated for temporarily storing data that cannot fit in RAM. When the system requires more memory than what is available in RAM, it moves the inactive memory pages to the swap file and makes room in the RAM for the active processes. This process is called swapping, and it helps prevent the system from crashing due to insufficient memory.

Enabling a swap file is a relatively simple process that can significantly improve the performance of a server. However, it is important to note that using a swap file is not a substitute for adding more physical memory to the server. Swapping can slow down the server's performance, as accessing the hard drive is much slower than accessing RAM. Therefore, it is recommended to use a swap file as a temporary solution until the server can be upgraded with more memory. In addition, it is important to properly configure the swap file size, as having too small of a swap file can lead to out-of-memory errors, and having too large of a swap file can waste valuable hard drive space.

To enable swap on a Cloud Linux server, you can follow these steps:

Check if there is an existing swap space by running the following command:

swapon -s

If there is no output, it means that there is no swap space on the system.

Create a swap file of the desired size using the following command:

sudo fallocate -l <size> /swapfile

Replace <size> with the desired size of the swap file, for example, 1G.

Set the appropriate permissions on the swap file:

sudo chmod 600 /swapfile

Mark the file as swap space using the following command:

sudo mkswap /swapfile

Enable the swap space:

sudo swapon /swapfile

You can verify that the swap space has been enabled by running swapon -s again.

Make the swap space permanent by adding an entry to the /etc/fstab file:

/swapfile none swap sw 0 0

This will ensure that the swap space is automatically enabled after a reboot.

That's it! You have now enabled swap space on your Cloud Linux server.
