The database is one of the main and most important elements that every software element needs to work. A website, a simple mobile application, an operating system, or an accounting application that is supposed to work with specific data, content, or information needs a database to store this information in a systematic classification for use in the application. MariaDB is one of these databases that we are going to fully review in this article and tell you the Top 10 Benefits of Using MariaDB for Your Database.

What is MariaDB?

MariaDB is a professional database that can fully cover your database needs. Many big names in the world of software and the internet have changed their process and addressed the users of this robust database. MariaDB is a well-rooted database that has evolved from one of the most powerful databases out there.

This database started its work in early 2008. Compared to other database programs and platforms that exist, MariaDB can be considered a new program. Of course, other platforms have been presented after this platform and have made good progress, but MariaDB, using MYSQL foundations, was able to make good progress and gain the attention of many programmers. We suggest you visit the Linux VPS server plans provided on our website and don’t miss the exceptional opportunity to have a powerful and high-speed server.

Top 10 Advantages of MariaDB for Database

1) Security measures

Security is a major concern for any website owner. Hacking attempts are increasing every year and a breach can have serious consequences. Consequently, it is important to ensure that your database management software is properly secured.

MariaDB security measures include:

• Built-in security checks and passwords
• PAM and LDAP authentication
• User role
• Database encryption

Another unique point of MariaDB is its RBAC role-based access control. This feature has been introduced since version 10.0.5 and makes access management easier.

2) Fast and Efficient Performance

The performance of your site is very important. Especially when the site’s loading speed drops. For example, most users expect a website to load in less than two seconds. Failure to achieve this time can lead to an increase in the bounce rate.

MariaDB considers engine-independent table statistics when optimizing queries. The MariaDB-based website also offers a range of useful resources on how to further optimize performance, as well as performance strategies, for various data representations. This includes system variables, buffers, stores, threads, performance improvements in database type, and encryption technology. This means that MariaDB is much less likely to negatively impact your site’s page speed.

3) Proper Support

Whether you’re a beginner or an experienced user, there will likely be times when you need extra support. Those licensed to dedicated MySQL products have access to Oracle Premier Support, which provides 24/7 assistance. MariaDB support is the same but has some additional features, such as a guaranteed response within 30 minutes! The continued use of this platform by these companies can be another reason for the importance of using MariaDB.

4) Storage Engines

Storage engines have been well developed in MariaDB and can provide new features to users. XtraDB and Aria can be mentioned among the mentioned storage engines.

5) Database Views

One of the main things that has been optimized is database views. A database view shows the information that will be provided to the user in the form of a virtual table based on the user’s request from the database. This virtual table can have related columns, each of which is in a separate table. Likewise, it may also collect different records and provide the user with a query answer at once.

6) Virtual Columns

Virtual columns can consider one of the great innovations for MariaDB, which greatly reduced the computational load of various programs. At the end of the tables of this database, a virtual column that does not belong to the database and is located in software and virtual form is created. This column will be able to perform mathematical operations and formulas that are requested from it on different rows of the application table and save it.

With this, it is no longer necessary to extract information from the tables in the program source and perform calculations on them. The program simply accesses that column and reads the necessary calculated information from it. If the calculation is done in the program, the system resources are consumed, and the execution time increases. This makes the database a little bigger, but the system resources are used more optimally.

7) Column Store

Columnar storage is one of the features built into MariaDB. By using this possibility, you can store the desired data in column form. This is in stark contrast to previous methods where data was stored in rows. In row storage, a lot of volume and time was spent due to the different data of each column. But this work has made it possible to use compressions and different techniques to increase the speed, and it can be very useful for big data as well as in the topic of Big Data.

8) MyRocks Support

MyRocks offers a database system (RockDB), which can considering the best in data compression. By using the MyRocks engine, you will have the ability to take advantage of the compression features of this database. It is also possible to move data between these two databases and change the basis of your database without making any changes.

9) Thread Pooling

Thread Pooling was created exclusively for MariaDB. This feature completely revolutionized the way databases work, allowing each access to the database to have a thread. This feature gives the database a special account that handles data requests with pooling software techniques. In this technique, a section named Pool is created, which acts like a list, and all requests are placed in it. Then the database elements manage and respond to these requests with different and sometimes multiple threads.

With this, your database will be able to respond to queries and requests for information faster. This feature provided by MariaDB has been expanding and many databases are leaning towards it.

10) Implementation and Authorization

This software runs on Windows, Linux, and macOS operating systems. It is available on Intel and IBM Power8 hardware platforms and runs as a service on multiple cloud platforms. Supported programming languages include C++, C#, Java, Python, and others. MariaDB Galera’s Linux-based cluster implementation has also been developed to provide a concurrent multi-master cluster option for MariaDB users. However, the API that connects the database to Galera Cluster, another open-source technology, starts in MariaDB by default, eliminating the need to load a separate cluster.

Conclusion

MariaDB is one of the reliable platforms that has proven itself in practice according to the comments and reviews we have done. Perhaps these introduced benefits are so tempting that you have thought of building your site’s database or the application you are planning to build on MariaDB and use it.

FAQ

Varnish Cache can act as an intermediary between the server and users. In such a way that it receives user requests and instead of sending the request to the server, it returns the corresponding web page from the cache memory to the user. Due to the application and importance of this issue, we decided to teach you how to set up Varnish Cache for Your Website after introducing you to Varnish Cache.

What is Varnish Cache?

Varnish Cache is a type of cache system that is used to accelerate website pages. This system receives website requests from users’ browsers and sends them to core or edge servers for processing. Then, the response to the request is stored in the cache memory and delivered to the users at a higher speed. This method improves the performance and loading speed of web pages.

If a similar request is sent to the website, Varnish Cache compares the new request with the previous request and returns the processing result from its cache memory to the user in case of similarity.

Another feature of Varnish Cache is the management of website user requests. If the user needs to display certain information from the website, it is possible to store the information related to the user in the cache using Varnish Cache. Therefore, whenever a new request is sent by him, the response will be sent to the user quickly from the cache memory.

Regarding the use of Varnish cache, it should be noted that this system is not effective by default for content that has an expiration time. In this case, this problem should be solved by using TTL in cache varnish.

Varnish Cache can also be useful for websites in terms of security. It will give attackers less opportunity to attack the main server infrastructure and protect your site from DDoS attacks. We suggest you use the Windows VPS server plans provided on our website to run your website.

Features of Varnish Cache

• Speed

• Savings

• Scalability

• Protection Against Outages

• Flexibility

• Experience

Use and Configuration of Varnish Cache

Varnish Cache is located on the server side and is deployed as a software module among the server layers. This software is designed using C language and can be installed on different operating systems.

In order to activate the Varnish cache for the website, we must place it as a layer between the server and the browser. If the content of the request is available in Varnish’s cache, Varnish will respond directly to the browser. Otherwise, the request is sent to the main server and after receiving the response, it is stored in the Varnish cache. With this, the page load time is reducing and the server load is also reducing.

To install and configure Varnish Cache for your website:

1- First, install the Varnish software.

To install Varnish on the Linux operating system, you can use the software repositories available on the operating system. There is also software available to install Varnish on Windows and Mac.

2- Find and open the Varnish configuration file in /etc/varnish/ or /usr/local/etc/varnish/ (depending on the operating system and Varnish version).

3- In this configuration file, specify the port number of Apache or Nginx where your web server works. For example, if your web server is running on port 80, change the port number to 8080.

4- Allocate some system memory to Varnish Cache. This value should be greater than the volume of web server responses. Usually, 20 to 30% of the total system memory is considering cache memory.

5- Launch Varnish Cache by running the following command:

sudo service varnish start

6- Now you can connect your web server to Varnish Cache so that its responses are storing as a cache in Varnish Cache. To do this, you need to specify the Varnish port number as the web server port in your web server configuration file.

Functional Codes for Varnish Cache Management

Some useful code for Varnish Cache is listed below:

vcl_recv: This code is executed when a request is received. By using this code, you can make changes to the received requests.

vcl_backend_response: This code is executed when receiving a response from the Backend.

vcl_deliver: This code is executed when the response is sent to the user. You can use it to deliver responses that have been manually modified.

vcl_miss: This code is executed when a request is missed with the cache key.

vcl_pass: This code is executed when a request is completely sent to the backend. Using this code, you can also edit the operation before sending the response.

vcl_pipe: This code is executed when a request is sent as a pipeline.

How to Install and Setup Varnish Cache for Your Website

First, you need to disable the Varnish version in the default repository by running the following command:

sudo dnf module disable varnish -y

In the next step, you need to install the EPEL repository using the following command:

sudo dnf install epel-release -y

Now it’s time to download and install Varnish Cache by running the following commands:

wget https://packagecloud.io/install/repositories/varnishcache/varnish70/script.rpm.sh

sudo bash script.rpm.sh

sudo dnf install varnish -y

Finally, you can enable the varnish cache by running the following command:

sudo systemctl enable --now varnish

Open the Varnish configuration file using the following command:

sudo nano /usr/lib/systemd/system/varnish.service

Considering that the default port in Almalinux for Varnish is 6081, you need to search for it and change it to port 80:

ExecStart=/usr/sbin/varnishd \
-a :6081 \
-a localhost:8443,PROXY \
-p feature=+http2 \
-f /etc/varnish/default.vcl \
-s malloc,256m
ExecReload=/usr/sbin/varnishreload

Finally, you should save the configuration file and exit. Then restart Varnish Cache:

sudo systemctl daemon-reload

sudo systemctl restart varnish

How to Install and Configure Varnish Cache in Litespeed

To install Varnish cache in the LiteSpeed environment, you can use the following commands:

yum install varnish

Now you can start and enable Varnish Cache by running the following commands and view the installation status:

systemctl start varnish

systemctl enable varnish

systemctl status varnish

For settings in LiteSpeed, it is necessary to enter the LiteSpeed environment. To do this, click the Add button in the Varnish section from the Configuration > Server > External App menu. Then enter the following values:

Name: Varnish
Address: localhost
Port: 80
Load Balancing: No
Max Connections: 1000
Environment: production
Initial Request Timeout (secs): 60
Retry Timeout (secs): 0

Then click on the Save button to save the changes. Go to Configuration > Server > General and change the port to 8088 in the Default section.

How to Configure Varnish Cache in Apache

First, install, start, and enable Apache with the following commands:

sudo dnf install httpd -y
sudo systemctl enable --now httpd

Now you can enable HTTP traffic through the firewall:

sudo firewall-cmd --zone=public --permanent --add-service=http

sudo firewall-cmd --reload

In the next step, you can open the Apache configuration file with the following command:

sudo nano /etc/httpd/conf/httpd.conf

Look for the Listen 80 line and then change it to:

Listen 8080

Save the Apache configuration file and exit it, and then restart it by running the following command:

sudo systemctl restart httpd

Conclusion

Varnish Cache is one of the most popular cache software in the web world. This software is used to increase the speed of sites and improve the user experience. By using this software, the web pages are loaded faster and the loading time is reduced. Varnish Cache is a basic tool for some big sites like Wikipedia and Facebook. Using Varnish Cache is also very effective on high-traffic sites that have a lot of data and can significantly improve page loading speed. To use Varnish Cache, you can install it on your server and apply the necessary settings. In some cases, you may need to use plugins or extensions designed to manage Varnish Cache. Also, some web servers such as Apache and Nginx support Varnish Cache as one of their modules.

Every domain or website you visit uses one or more specific DNS. Now what is DNS and where is it located on the website and how does it work? These are the questions that may arise in the minds of users. DNS is a universal system that all websites and domains use, and without it, no website will survive. In this article, we are going to tell you What is a DNS Server and How Does it Work? We suggest that you do not miss this interesting post and stay with us until the end.

What is DNS?

DNS stands for Domain Name System, which converts a website’s domain name to an IP address. All computers on the Internet, from smartphones or laptops to website servers, identify and communicate with each other using numbers. These are called IP numbers.

When you want to enter a website and communicate with its server, you don’t need to enter its IP address. Instead, you only need to enter the domain name of the website and leave the operation of converting the “domain name to IP” to DNS. By doing this, the human-understandable domain name becomes a machine-understandable IP.

There are various plans for a dedicated server on our website. You can do the DNS configuration on a cheap dedicated server provided on our website.

What is a DNS Server or Nameserver?

When you enter a website address, you need to connect to the server IP associated with your domain. Now, where is this information and how does the system understand which domains belong to which server? A DNS server or Nameserver acts like a phone book and records all DNS records and IPs related to them. In other words, its task is to provide DNS information related to domains.

Usually, web hosting services manage nameservers. Every host or server you buy has its own IP address that needs to be registered. Each DNS server is responsible for storing information about the domain and IP servers in itself so that it can send the information when called. The DNS inside the Nameservers are spread all over the world and it should be available to all of them for identification. Therefore, domain DNS registration may take up to 48 hours.

Each Nameserver has its own DNS address that can store records of many domains and IPs. For example:

Ns1.neuronvm.com

Ns2.neuronvm.com

Each domain name must be at least two-way bound to DNS. Because the server and the main server and subsequent servers are used for times when the main server is not available. When a website’s domain address is called, your server’s IP information is read from the DNS server and sent to the browser, and then a request to receive the information is sent to your server.

How Does DNS Work?

As we said, DNS is responsible for returning the IP from the domain. This operation is carried out in several steps until finally, a valid and healthy IP address reaches the user. It is a little difficult to find the IP address of the website among all the DNS servers in the world, which is made easy by the DNS architecture. Each of these steps will help you find the original DNS by sorting out where the DNS is stored. For example, first, the DNS zone and then the DNS servers related to their back-domain are checked in order to reach a suitable location.

1) DNS Recursor

In the first step, the user’s request is sent to this section. This section communicates with the set DNS servers to find the IP. To do this, it sends queries to the next three parts, i.e. Root Nameservers, Top-level Domain Nameservers, and Authoritative Nameservers, to find the right IP.

2) Root Nameservers

This section is for finding the DNS root zone or DNS from its zone. This section is responsible for responding to requests placed in the same DNS zone. Finally, a list of valid servers matching the domain’s TLD will help find the IP address.

3) Top-level Domain Nameservers

It is responsible for keeping the IP related to the TDL of the domain and sends the existing IP and reaches the fourth stage.

4) Authoritative Nameserver

Returns the real and final IP address. At this stage, there are two types of servers: the first server is the main server, which is the main IP set in the first DNS, and the second server is your alternate and backup DNS. If the primary server fails, it uses the secondary server and returns the final IP.

What is a DNS Cache?

A cache system means temporarily storing data in a closer location, which leads to improved performance and faster response. DNS caching means storing DNS information in the closest location to the user. When sending subsequent requests, the DNS response is read from the user’s cache and no more requests are sent to the DNS chain. Finally, CPU bandwidth consumption decreases, and website loading speed increases. DNS data can be stored in various cache locations and for a specific time period in terms of TTL.

DNS Cache Location in the Browser

By default, web browsers support DNS caching and store information about each DNS for a certain period of time so that the DNS response can be read from the browser when it is reloaded. When you open a domain address, before sending a DNS request, the browser cache is first checked, and if there is no information, the request is sent to the DNS chain. In the Chrome browser, you can see the status of the current DNS cache by going to the following address:

chrome://net-internals/#DNS

The Best DNS Servers

Usually, the web hosting service provides you with DNS servers, but you can still change your domain’s DNS. There are free and paid DNS servers that are very fast and secure and use security tools such as firewalls and request filters. Next, we will introduce some of the top DNS servers.

Cloudflare: Cloudflare is one of the DNS provider services that provides many features to users. In addition to security, Cloudflare prevents DDoS attacks and other attacks and optimizes the security and loading speed of your website with security services and optimized architecture.

Google Public DNS: Google’s DNS service, which is called Google Public DNS, is slightly different from Cloudflare’s service and is designed for more experienced users. This service has its own uses and facilities that you can use if needed.

Quad9: Quad9 DNS service is famous for its speed. Also, the service claims to be able to block malicious websites and users using its data.

Conclusion

DNS is the communication system between the domain name and the server IP, which ultimately shows the server information to the user. DNS consists of 4 parts, all of which eventually reach the IP server. Also, there are different ways to change domain DNS records (such as NS records and A records) you can connect your server IP to your domain in different ways. Another point is that you can use DNS services to maintain security and speed.
