Setup CloudFlare CDN for WordPress on Google Cloud


This article covers how to setup Cloudflare CDN for WordPress on Google Cloud. Google Cloud CDN (Content Delivery Network) uses Google's globally distributed edge caches to cache HTTP(S) Load Balanced content close to your website visitors or users. Basically, Google Cloud CDN leverages Google's globally distributed edge points of presence to accelerate content delivery for websites and applications served out of Google Compute Engine and Google Cloud Storage. Cloud CDN lowers network latency, offloads origins, and reduces serving costs.


How to Activate Google Cloud CDN on Google Cloud Platform ?

  • Login to Google Cloud platform (GCP).
  • Under Network services select Cloud CDN.
  • Click on Add origin.
  • Next, just select the load balancer from origin drop-down and click add.

Boost performance of Websites using Cloudflare - Tips to implement it


This article covers how to improve the performance of Websites using Cloudflare. Website speed has a huge impact on user experience, SEO, and conversion rates. Improving website performance is essential for drawing traffic to a website and keeping site visitors engaged. 

Along with the caching and CDN, Cloudflare helps protect your site against brute-force attacks and threats against your website.

Cloudflare has the advantage of serving million of websites and so can identify malicious bots and users more easily than any operating system firewall.


CDNs boost the speed of websites by caching content in multiple locations around the world. CDN caching servers are typically located closer to end users than the host, or origin server. Requests for content go to a CDN server instead of all the way to the hosting server, which may be thousands of miles and across multiple autonomous networks from the user. Using a CDN can result in a massive decrease in page load times.


How to get started on optimizing website performance with Cloudfare CDN (content delivery network)?

1. Optimize images

Images comprise a large percentage of Internet traffic, and they often take the longest to load on a website since image files tend to be larger in size than HTML and CSS files. Luckily, image load time can be reduced via image optimization. Optimizing images typically involves reducing the resolution, compressing the files, and reducing their dimensions, and many image optimizers and image compressors are available for free online.

2. Minify CSS and JavaScript files

Minifying code means removing anything that a computer doesn't need in order to understand and carry out the code, including code comments, whitespace, and unnecessary semicolons. This makes CSS and JavaScript files slightly smaller so that they load faster in the browser and take up less bandwidth.

3. Reduce the number of HTTP requests if possible

Most webpages will require browsers to make multiple HTTP requests for various assets on the page, including images, scripts, and CSS files. In fact many webpages will require dozens of these requests. Each request results in a round trip to and from the server hosting the resource, which can add to the overall load time for a webpage. 

4. Use browser HTTP caching

The browser cache is a temporary storage location where browsers save copies of static files so that they can load recently visited webpages much more quickly, instead of needing to request the same content over and over. Developers can instruct browsers to cache elements of a webpage that will not change often. Instructions for browser caching go in the headers of HTTP responses from the hosting server.

5. Minimize the inclusion of external scripts

Any scripted webpage elements that are loaded from somewhere else, such as external commenting systems, CTA buttons, or lead-generation popups, need to be loaded each time a page loads.

6. Don't use redirects, if possible

A redirect is when visitors to one webpage get forwarded to a different page instead. Redirects add a few fractions of a second, or sometimes even whole seconds, to page load time

ACK flood DDoS attack


This article will guide you on methods to prevent ACK flood #DDoS #attack. An ACK flood DDoS attack occurs when an attacker attempts to overload a server with TCP ACK packets. 

Client requests connection by sending #SYN (synchronize) message to the server. Server acknowledges by sending SYN-ACK (synchronize-acknowledge) message back to the client. Client responds with an #ACK (acknowledge) message, and the connection is established.

When computers communicate via TCP, received packets are acknowledged by sending back a packet with an ACK bit set. 

The TCP protocol allows these acknowledgements to be included with data that is sent in the opposite direction. 

Some protocols send a single acknowledgement per packet of information.

To stop a SYN #DDoS attack:

1. Filtering.

2. Increasing Backlog.

3. TCP half-open: The term half-open alludes to TCP associations whose state is out of synchronization between the two potentially because of an accident on one side.

4. Firewalls and Proxies.

5. Reducing SYN-RECEIVED Timer.

6. SYN Cache.

7. Recycling the Oldest Half-Open TCP.
