We have seen a massive increase in the “real world” dependency on digital services in the last few years. This process will probably continue in the future, and we are not ready for it. In the same few years, we have seen a lot of cases where digital services went offline or got hacked. In a society that relies more and more on digital services, we can not afford such services not to be available or secure.Read More

I often see people and companies moving their workloads to the cloud. Speaking with them, they explain that the cloud is cheaper, more flexible, and more reliable than their current infrastructure. To further increase investment return, they often target a specific (single) cloud to reduce management costs and complexity.
By itself, this trend seems a very reasonable one. The risk is that, sometimes, people do not consider the less immediate risks around this move.Read More

In the last couple of weeks, I’ve seen problems allocating resources in the Google Cloud Platform in the Frankfurt region.

A couple of days ago, I did re-take the AWS Certified Solution Architect - Associate exam. This was my second time at this certification (I did it the first time in 2015), and I had to retake the exam since my certification expired in 2017. The exam was fairly different this time from the previous time.
The first thing I noticed is that the certification itself is no longer expiring after 2 years since the validity got extended to 3 years.Read More

As part of my AWS re-certification path, I decided to start from the very begin, with the AWS Cloud Practitioner Essentials. I was sure to pass the exam, but since in the company I work for other people will be required to become AWS certified, I wanted to check out the exam beforehand, to be able to suggest to the people the right certification for them.
The exam is fairly straight forward and is mainly focused on the advantages of AWS and cloud in general.Read More

After the article on the reasons to use vanity URLs in Go and the one about how to implement a lightweight vanity URLs provider, I’d like to share with you how you can leverage AWS Lambda to implement a vanity URLs provider.
The first thing we will need is to import the github.com/aws/aws-lambda-go package. This package will provide us with the needed functions to easily integrate our Go code with AWS Lambda.Read More

Today the IT world is moving very quickly from the classic infrastructure with servers, switches, hard disks and so on to virtual infrastructures, where all those things are simple pieces of software faking to be real objects. This has huge benefits, and this is why so many companies are doing this. Along with the advantages, this new way of doing IT has it’s criticality that the administrators have to know to prevent possible problems to happen.Read More
