When you hand over developers new VM(s), or when you have just created a critical env for your team, remember to be prepared for low disk issues.

If you don’t, it will bite you sooner or later. More annoying, it usually come out as a recurring issue. Evaluating the total support effort, we might get a much bigger number than we thought. Are you feeling the same, my friend?
So how we can make low disk issues less likely to happen? And when it does happen, how we can resolve it faster with less impact?

Use Nmap To Automate Insecure Ports Check

While go cloud is a prevailing trend, security is something we can’t afford to ignore. People hate malicious access. Periodically check all widely open TCP Ports is one good practice to secure our system in cloud. Obviously DB ports can’t be exposed to the whole internet. Our internal REST API also need to be protected.

We should make sure firewall is properly configured. What’s more important, we need to be always on top of these security holes with minimum efforts. So let’s automate the audit process of insecure TCP Ports.

Easy and Reliable Sandbox Setup Matters

Sandbox indicates an isolated and autonomous play-yard, where anyone can do their own code build, deployment and debugging locally. It won’t effect anything outside. Ideally it should not be effected by outer world either. This is especially useful for new member on-board, daily development, QA cycle, etc.

How to get an easy and reliable sandbox for your projects? Check it out.

Surprisingly daily deployment doesn’t always succeed like we expect, even if no major changes*. More interesting, many failed tests are kinds of false negatives. So what are the obstacles? And how we can avoid them?
