When it comes to backing up old digital data there are a lot of various options to storing data in different formats.
This could vary between different medium types, disk setups, connectivity etc.
The two main types of data setups include Hot (or) Active data storage, and Cold data storage.
What's the difference between hot and cold storage mediums, and why does it matter ?
Hot data is active information that changes and is used daily. That means it has to be agile and on standby.
Cold data is inactive data that retains mostly static information. For example bulk data that only gets read on infrequent intervals.
This information (cold data) is considered valuable when inactive, as the speed of access is not a priority, but managing where it is kept is.
Hot and cold data both have their advantages but are defined by their differences. The benefits that come from separation have a big impact on the success of business operations.
Hot storage mediums are usually always online and network connected for quick and fast access.
Cold Storage mediums can consist of offline or offshore data storage for security and controlled accessibility.
A simple and effective hot storage medium can consist of something like a cloud data storage or, a local storage server.
you can purchase a cloud server from popular storage providers like AWS, Google or Azure.
If you plan to construct your own local enterprise storage server, take note it will require a lot of components and software to setup.
what's the difference between a local and online cloud host for data storage ?
Cold storage mediums are usually based on local storage mediums that are offline and not readily accessible.
Bulk data storage is usually done with cold storage mediums.
This would include storing data for long terms and aren't meant to be touched and modified.
Cold storage's are quite similar to local hot storage's, but differ by being offline most of the time.
Cold storage needs to be impermeable to data loss and corruption over long time periods.
Its typically driven by redundant disk arrays or RAID storage solutions to reduce possibilities in case of an awry situation.
Parameters: | Hot Storage | Cold Storage |
Access Speed | Fast | Slowest |
Access Frequency | Regular | Rare/Very Less |
Data Exchange Volume | High | Low |
Storage Media | Standard hard drives, solid state drives, portable flash memory, easy-access cloud storage | Off-site archival cloud storage (Amazon Glacier, Google Coldline), unplugged & encrypted hard drives |
Security | Lower | Higher (physical access required in some cases) |
Cost | Highest | Low |
Ideal User | Everyone (Enterprise or Personal Usage) | Enterprise or Personal with large backup data to be offloaded. |
Depending on your needs and use cases, a hot or cold storage system may or may not be applicable to you.
If you are looking for something that requires:
You might want to consider hot storage solutions that are online, or offline.
Otherwise cold storage options or maybe "warm" storage.
It is similar cold storage but exhibits the accessibility and available state of hot storage.
Just not as fast considering it is much more larger in comparison.
Thus if you are looking to create a hot or cold data storage for your data, consider between the options available and chose accordingly.
Not every business has the same needs, and different data has to be split in between hot and cold storage options.
the choice is based on the various parameters like ease of accessibility and size.
Webserver hosting comes in all sorts of sizes and shapes, depending on your needs you have to choose an optimal webserver that suits your organization.
Here's a list of the various types of Webserver hosting options:
Each one of these has its own variants, upsides and downside which we will list:
Dedicated webservers as described, they are a dedicated server maintained only for individual/personal organizations and nothing else.
They are single handedly the fastest and can handle more for the given resources compared to other offerings.
Dedicated webhosts have variations such as:
These dedicated webservers are quite simply the most basic webservers that are very lightweight and fast as they have no overhead
It's as simple as a dedicated computer, running a light OS, and hosting the webserver.
Virtual Host webservers are just like the aforementioned webservers, the catch being the hosting OS runs on top of a Hypervisor/Virtual Container.
This helps with maintenance of the system and control over the hosting system.
Bare Metal webservers are quite more cumbersome to deal with in maintenance situations.
Shared webservers in essence are servers that do shared tasks along with webhosting such as hosting other servers on the same system.
Since multiple tasks run on the same system, The resource usage is dynamically managed.
However if one task is in a state of using heavy resources it will affect other tasks.
Shared hosting can also be bare metal or virtually hosted.
VPS services essentially provides the same kind of experience as a dedicated host but are organized in the same way shared hosts do.
Your webserver will be hosted a on cloud with limited resources, but it has full control for maintenance and is given various protection services like anti-DDoS protection, etc.
VPS services provide peace of mind as it doesn't involve too much of the design process for a proper hosting setup.
Instead, it's a set it and forget it type of service.
For more detailed info about VPS services check here.
Hostinger is a popular VPS that offers this service.
Shared and Dedicated webhosts fall into more of a similar category of self-hosted webservers, whereas other services like VPS fall into the cloud-hosted/external hosting services.
If your organization doesn't have a complex need and just needs to host a simple static web page, external hosting might be a cheaper option.
Given the complexity and available resources, self-hosting might seem more reasonable.
If you expect less traffic but want to be able to manage the server on your own, consider self-hosting.
For larger commercial organizations, self-hosting again might seem more reasonable.
If you are a single individual or a smaller commercial business, cloud-hosted/external hosting is just much more feasible, considering network limitations as well.
In short, we were able to list down the various options for hosting a webserver for an Individual's needs.
may it be commercial or Individual.
If you host a webserver, a very important that its running optimally and is in proper conditioning.
Here is a small guide to various easy diagnostic tests you can check to see if you webserver is running up to grade.
Depending on your OS distribution running your webserver the installation methods may vary, However all the tools are all usually the same.
All of them can be invoked from the command line terminal or SSH shell, given that your webserver may be running on a remote system.
The tools include:
ping is a simple utility to see if your system is able to respond to systems on the network and check latency.
This comes pre-installed on almost every operating system.
A simple command to check if you are able to communicate with google DNS servers for example:
ping 8.8.8.8
Htop is a simple system utility to see system runtime stats like CPU usage, RAM usage, processes, etc. kind of like a task manager.
Install it on:
Ubuntu, and Debian derivatives:
sudo apt install htop

Ubuntu, and Debian derivatives:
sudo apt install nload
Fedora, OpenSUSE, and other RedHat derivatives:
sudo dnf install nload
Manjaro, and other Arch derivatives:
sudo pacman -S nload
Run it with:
nload
(P.S pressing tab switches between network devices like ethernet and wifi to see how much traffic passed through each one)
If you are looking for a more overall system view, you might want to consider using glances.

Ubuntu, and Debian derivatives:
sudo apt install glances
Fedora, OpenSUSE, and other RedHat derivatives:
sudo dnf install glances
Manjaro, and other Arch derivatives:
sudo pacman -S glances
Run it with:
glances
Knowing these various parameters is all well and good, But one must know how to make use of them to analyze and troubleshoot issues with their webserver.
For example:
There are a lot of simple diagnostic tools for checking the server status. If you are looking for a graphical dashboard, consider using the cockpit-project.
