​​Rover is a tool to visuzlize your Terraform resources and their relations for better understanding of what's going on in your systems.

Rover:
- Generates a plan file and parses the configuration in the root directory.
- Parses the plan and configuration files to generate three items: the resource overview (rso), the resource map (map), and the resource graph (graph).
- Consumes the rso, map, and graph to generate an interactive configuration and state visualization hosts on localhost:9000.

Our friends from Cossack Labs have released a new version of their Acra tool.

Acra is a database security suite for data protection. It provides application-level encryption for data fields, multi-layered access control, database leakage prevention, and intrusion detection capabilities in one suite. Acra was specifically designed for distributed apps (web, server-side and mobile) that store data in one or many databases. Basically, you can encrypt individual fields completely transparent for an application!

So, what's special about this release? A lot of features that previously were available only in the enterprise version now made their way to open source! Among them: database encryption, searchable encryption, and encryption-as-a-service API.

Apart from that, Acra allows to tokenize certain fields in your database to achieve anonymization. This is actually a cool feature! In one of my former companies we had to create our own tool to achieve that. Here you get it as a part of the package.

On our last voice chat we briefly discussed Kubernetes autoscaling and mentioned Karpenter - a cluster autoscaler backed by AWS.

This tool isn’t new. However, but AWS started to promote it recently. So, it’s probably “production ready enough” from their judgment. Also, it looks like Karpenter can work with spot instances, which makes it a super-interesting tool to follow.

You can read more about it in the AWS blog post.

If you are already using it or you have tried it, feel free to share your opinions in our chat!

I don’t work with the databases much lately. Moreover, I haven’t worked with MySQL/MariaDB for a long time. Thus, I am not 100% sure how useful is this tool, but I found it in the reliable source.

mariabak is a CLI for mysqlsump that eases certain operations. So, you don’t have to pass multiple mysqldump commands for certain jobs.
