• We have chosen the globally recognized full-stack web programming and technologies for the creation and production of each web design project.

Build up more professional images for the client company email

• The company email has become an important communication bridge between clients and customers, and it is also an important asset of the company. Because the company email preserves the daily clients to customers communication and email content, which involves many conversations, business decisions, or day-to-day resolutions. So, to leave a good impression on your customers, you must have a representative company email.

• Through the configuration of the Email SPF, DKIM and DMARC, we make the client company email can be delivered to the target customers mailbox more safely and effectively, thereby enhancing the target customers impression of our client company.

  

Linked together MySQL Database Clusters

• MySQL Database Clusters are composed of multiple database instances to meet high read & write and operation intensive database environments, and are developed to meet the most demanding applications in many industries (For example: Social Media and Online Shop Websites) requirement, especially for industries that require 99.9% reliability of database operation (Excluding database maintenance and restart times).
  

  Each MySQL Database Cluster instance supports 6000 available backend connections (Take our current calculation of 64 GB RAM memory for each instance as an example). If you are interested to learn more about the functions and applications of MySQL Database Clusters, please go to the “White Papers – Extending the Web Application Repository with MySQL Clusters (Traditional Chinese version)” page.

  

NVMe SSD disk over 2.0 GB per second

• We use NVMe SSD disk with high-speed I/O performance to enhance better data transfer speeds and overall website experience.
  

  The following picture shows the reference data for testing the continuous read and write speeds of our server to 1 GB file using the SSH command:

  

Varnish Cache – A high-performance HTTP accelerator

• Varnish Cache is a set of high-performance HTTP accelerator designed for content-heavy dynamic websites and APIs (Mobile Apps & Native Apps Programming).
  

  The following picture shows the application integration reference of our company website using Varnish Cache and Amazon CloudFront Global CDN (From early 2023, we have removed and unset the list of HTTP header fields, including http.x-url, http.x-host, http.Server, http.X-Powered-By, http.X-Varnish, http.Age, http.Via, http.Link, http.X-Generator, http.X-Mod-Pagespeed and http.X-Ngx-Pagespeed etc.) :

  

• What is Web Cache and how does it work?

  Whenever going to a website, the website needs to render the content of the page, and use PHP (PHP-FPM) to request the page data from the MySQL / PostgreSQL database. Therefore, a server system requires a CPU and RAM memory to operate.

  If multiple global end users access a website at the same time, the server system will take up a large amount of the CPU and RAM memory for processing, and the rendering speed of the content of the page will become very slow. In this case, the website needs a caching system to avoid rendering and presenting the same page content over and over again. The caching system can automatically generate static HTML files and store them in the cache folder specified by the server. Whenever a new end user visits, the website renders the content of a static HTML page to new end user and greatly reduces the pressure on the server system and shortens the loading time of the content of the page.

  In addition, the speed and time it takes for the website loading (For example: Largest Contentful Paint (LCP), First Input Delay (FID) and Cumulative Layout Shift (CLS) mentioned in the optimization guide) are important for search ranking and its algorithm. Because, the caching plugin that shorten your website’s page loading and loading time are one of the most important factors to enhance your website’s SEO ranking.

Redis in-memory database – Average read and write operation times below one millisecond

• Redis is an in-memory database, NoSQL key-value database, and is mainly used as an application cache and quick response database. Because it stores data in internal RAM memory instead of Solid-State Drive (SSD) or NVMe SSD. So, Redis offers unparalleled speed, reliability, and performance (Take our current server with DDR4 3200MHz RAM memory speed as an example, its Peak Transfer Rate is 25.6 GB per second).

  Whenever an application relies on external data sources (For example : MySQL / PostgreSQL database), the latency and throughput of these data sources can create a performance bottleneck, especially as traffic increases or the application scales. In these cases, one way to improve performance is to store and manipulate data in RAM memory storage that is physically closer to the application. And Redis is built to perform this task: It stores all data in-memory, provides the fastest data read and write performance, and provides built-in replication capabilities that let you place data physically closer to the user for the lowest latency.

  The following picture shows the reference of our company website using Redis in-memory database and new Redis Zstandard (Zstd) lossless data compression algorithm:

  

• Should I use Varnish or Redis? Which one is better?

  Varnish is a server-side Web Cache / Page Cache mechanism; while Redis is an in-memory database, which implements object caching through application, and stores database query or complex operation results in the object in the form of key-value.

  Varnish and Redis can be used together at the same time. These two caching mechanisms have different advantages and uses, and are especially suitable for high-end and global levels websites, because it is a high-performance caching solution that can greatly improve website performance and throughput.

  While our Varnish and Redis are configured and completed at the server-side levels, if the client Company Website or Online Shop Website is hosted on our Server Cluster Environment, Varnish and Redis are pre-configured.

  Because we take care of all caching issues for you.

Important Website Performance Metrics – Time to first byte (TTFB)

• If a website takes a long time to load, this can adversely affect user experience, website traffic, and SEO. A performance-optimized website has an advantage over a slow website.
  

  The following picture shows the reference data of our company website using Google Chrome Incognito Window (Desktop computer web browser) for two test results:

  

Improve website speed and avoid sudden network congestion

• All of our servers use the HTTP/2 network protocol, Google Brotli Lossless Compression Algorithm and Google BBR Congestion Control Algorithm to improve website speed and avoid sudden network congestion.

Yoast SEO & Google Schema Structured Data Markup – Get higher rankings in search engines and gain more trust from customers in the digital marketing market

• The CMS backend system of our WordPress Professional Company Website Plan and/or WordPress Online Shop Website Plan can use Yoast SEO Artificial Intelligence (AI) to provide further guidance suggestions and options for the client website, such as setting Focus keyphrase, Search Engine Results Page (SERP) preview, SEO title, Meta description and SEO page analysis and other useful functions for each individual web content page.

Protect our clients websites, API gateways and web applications

• We prefer to use Cloudflare Global CDN and Cloudflare DDoS Resistance Attack Protection as the first line of protection for our servers and clients websites.
• Cloudflare Global CDN – To reduce potential and attacked areas, we put most of our computing resources on the Global Content Delivery Network (CDN) so that the Internet traffic cannot directly flow to our basic server facilities.
• Amazon CloudFront Global CDN – We merge and adopt the CloudFront Origin Shield to protect our origin servers in the shortest AWS region in global CDN deployments (The effect is to establish a security shield protection at the frontend of our basic server facilities to provide additional protection against high-load traffic and reduce the number of retrieved content and requests from the global CDN server to our basic server facilities).
• Cloudflare DDoS Resistance Attack Protection – Using Cloudflare intelligent IP hided, Proxied and DNS controlled services, it can provide built-in DDoS protection and effective 5 seconds firewall protection;
  • DDoS L7 ruleset
  • Global L7 attack mitigations configuration – Automatic mitigation of HTTP-based DDoS attacks such as HTTP floods, amplification HTTP attacks, and reflection HTTP attacks.

The best secure website solution：A website programming that can constantly up to date and patch vulnerabilities quickly

Take the WordPress CMS for example. Many large multinational corporations, government agencies, commercial companies, charities and organizations all over the world like to use WordPress CMS backend system because WordPress CMS is the most popular CMS backend system in the world right now. The customizability, sustainability and extensibility of its core programming is very powerful.

The following world famous websites use WordPress as their CMS backend system

• The official website of The White House government
• The Official Microsoft Blog and Microsoft News Center
• University of Washington and Washington University in St. Louis
• The Foursquare Church and International Church of the Foursquare Gospel Hong Kong District
• Linode Global Cloud Service Provider
• Meta Newsroom (Facebook Newsroom)
• The official website of Sony Music
• The official website of Bianchi Bike from Italy

The information was taken from the above websites in mid 2023. All Company Name and Third-party Trademarks are the properties of their respective owners.

If you are interested to learn more about which websites are using the WordPress CMS backend system, you can search “Who uses WordPress?“

So clients don’t have to worry! Brands known for outstanding performance, safety and reliability are safer.

WordPress, Joomla, and OpenCart are the top brands of choice for web design and web technologies, as well as CMS backend systems for many major websites and online shops. Just like the Apple iOS and Google Android mobile phone systems we use every day, it is very safe and reliable.

In addition, for your peace of mind, we are cautious about aggressive Brute Force attacks from the Internet around the world. When we create a website or Online Shop E-commerce, we will set unique CMS administration login URL, enable Two-Factor Authentication (2FA) for CMS backend system login, using Google Authenticator or Microsoft Authenticator or receive One-Time Password by Email to login (Applicable to our creation of WordPress CMS backend system, WordPress CMS with E-commerce backend system, Joomla CMS backend system, Joomla CMS with E-commerce Business version backend system and OpenCart E-commerce backend system) and limit the number of login failures to enhance the overall security of the website.

To provide our client with more comprehensive security and protection in real-time monitoring of the Antivirus Engine, Virus Scanner and Website Firewall on the server-side and/or website

To ensure that the client website is safer and more reliable, we install server-side Clam AntiVirus (ClamAV) – Antivirus Engine and Virus Scanner and the client website (Each client CMS backend website and Online Shop E-commerce CMS backend system are different. Therefore, some of the module functions are not applicable to each client.) install website Firewall and Virus Scanner, which can be regular comprehensive virus scans, malware and program scans and removals, and security risk assessments can be performed for the entire website.

Clam AntiVirus (ClamAV) – Antivirus Engine and Virus Scanner

• Clam AntiVirus Exim (ClamAV and Exim integration)
• ModSecurity (Scan HTTP when uploaded files)
• Pure-FTPd、ProFTPD (Scan FTP when uploaded files)
• Suhosin – PHP extension (Scan when uploaded PHP scripts)

The following picture shows us using Clam AntiVirus (ClamAV) – Antivirus Engine and Virus Scanner to perform a comprehensive virus scan of the entire website directories and files:

Website Lock function on our Server Web Control Panel

The Website Lock function will completely lock the directories and files within the entire website, any changes are prohibited, such as adding or modifying web content, uploading new files, file modification and client self database backup and restore (Not applicable to our automatic server full mirror source and dual remote locations backups every day) etc.

This method is very practical and effective, and can almost 100% protect the client website. It is especially suitable for websites that are not updated frequently and only appoint one staff who can modify the website. If a client needs to modify your website or upload a new file, the client can simply unlock your Website Lock function temporarily.

The principles of our DDoS defense technology – Protect servers from Layer 4 to Layer 7 DDoS flood attacks from Internet

Reduce potential and Attacked areas

• Global Content Delivery Network (CDN) – We put most of our computing resources on the Global Content Delivery Network (CDN) so that the Internet traffic cannot directly flow to our basic server facilities.
• Only common communication ports of 80 (Transmission Control Protocol – TCP) and 443 (Transmission Control Protocol – TCP and User Datagram Protocol – UDP) are allowed – To ensure that websites, applications or other resources will not receive any communication and ports signals. Thereby the possible attack points are greatly reduced.
• Firewall IP Whitelist – Our servers will automatically check the IP address lists of each service provider’s for Global Content Delivery Network (CDN) to ensure our Transmission Control Protocol (TCP) and User Datagram Protocol (UDP) communication ports are unobstructed.
• Completely prohibit XML-RPC applications or Partially prohibit XML-RPC applications (Applicable to Mobile Apps & Native Apps Programming services clients)
• Although we use many different protection technologies to ensure that our clients websites, applications or other resources are also functioning properly every day and are not affected. Therefore, we will not encourage our clients to install free and/or third-party programming on their own websites, applications or other resources. The most common problem is that the programming contains potential malicious codes and scripts, which will repeatedly continue to attack, rewrite and refresh new data, eventually causing the entire website and database to crash and paralyze.

Advanced and Expansion measures

• Using Cloudflare intelligent IP hided, Proxied and DNS controlled services, it can provide built-in DDoS protection and effective 5 seconds firewall protection.
• The installed CSF (ConfigServer Security & Firewall) server firewall on our servers limits incoming traffic, blocks common flood ports, limits thresholds and manages rate and burst values. Thereby, mitigating the impact of large-scale DDoS attacks on the basic server facilities.
• Nginx combines iptables to limit the number of source requests per minute – Slow down the bandwidth (or transmission) capacity of the attack.
• Cron Jobs checks the server’s traffic every minute for abnormality – Check the server’s traffic every minute and email alerts will be sent in the event of an accident.
• Brute Force Monitor – View, research, and understand the source of traffic, and make a preventive deployment before an accident occurs.

For more Complex attacks and Deployments

• The best way is to use a Web Application Firewall (WAF) to further prevent the DDoS attacks (For example : ModSecurity, Comodo ModSecurity and Comodo WAF (CWAF))
• Participate in Cloudflare – Pro to Enterprise solutions to resist complex DDoS attacks (More details)
