Last December Amazon announced its new EBS gp3 volumes, which offer better performance and a cost saving of 20% compared to those that have been used until now (gp2). Well, after successfully testing these new volumes with multiple clients, I can do nothing but recommend their use, because they are all advantages and in these 2 and a half months that have passed since the announcement I have not noticed any problems or side effects.

One of the biggest annoyances when working with AWS and your Internet connection has a dynamic IP is that when it changes, you immediately stop accessing to all servers and services protected by an EC2 security group whose rules only allow traffic to certain specific IP’s instead of allowing open connections to everyone (0.0.0.0.0/0).

Creating a MySQL or MariaDB user and granting permissions to him to access a specific database and be able to write data on it is a very usual task that is necessary to perform each time you install a new application based on any of these database engines, like web applications running on top of LAMP stack. Whether it is a simple WordPress, or a more complex application tailor made, one way or another you will always have to complete these steps at some point before its deployment.

One of the most targeted goals when optimizing a website for page load speed is to get a good score on Google PageSpeed Insights test. But it is not enough to work hard on optimization, achieve a good score and go to sleep. It is essential to periodically monitor score changes as a website evolves and undergoes changes over time which affect this metric.
Here’s a little script that will allow you to automatically track Google PageSpeed Insight score and be alerted if it falls below a custom value.

What if you could replace the button provided by Facebook with a single and simple image of the same button showing up-to-date number of followers of your Facebook page? It would be fantastic for website performance optimization or WPO, because it would only require a single additional request to the server, and it could be served and cached quickly from a CDN very close to the user’s geographic location. In this way you could ensure that the loading speed of your website would remain very high and without performance penalties.
How can this be achieved? It seems a win-win solution too good to be true… Well, it can be achieved in a much simpler way than you think thanks to the Imagemagick library and a simple Bash script. Read on…
