In the past, we were using the VPN solution from AWS, and even though the per-hour cost seems cheap, the truth is the costs scale quickly when the whole team needs to be connected. We were a small team.

In a previous post, we discussed the power of reserved instances for compute services, and this case is no different. We will see an example of how a commitment can help to reduce your database expenses.
Although this is not the only way to reduce database costs, it is a quick and effective way to achieve it. In a few steps, you will be able to set it up, and it will be running the next day.

At some point in 2023, we were discussing costs and pagespeed. I quickly pointed out that the slow performance and spike in bandwidth costs were caused by the usage of .gif images.
