Imagine one or more of your systems is unavailable because of some malicious attack, whether a nasty virus, ransomware, or sabotage from a disgruntled employee. No worries, these things happen —  you’ll recover from backup. Except you discover that your backups have been compromised in the same manner (this has happened). This is usually where the term air gap gets dropped. Someone will say, “you need a truly offline backup — tape! There’s no way ransomware can get into a tape backup!” While that’s true, how long does it take to recover from tape stored in a land somewhere far, far away? If a backup takes so long to restore that there’s major financial or business impact, does it actually exist? Realistically, there are ways to protect your data stored by backup systems even without this gap. I recently wrote a blog post about immutable infrastructures, but compute infrastructures are not the only way that immutability matters in the data center. Immutable, by definition, means the state is set or inflexible once constructed. In other words, it cannot be changed. The goal is to build a more reliable automated compute infrastructure in order to enable stable continuous delivery. Data has become…
