You don’t save anything by moving to the cloud. Ask around – how many of the organizations you know who moved to the cloud have reduced operations headcount? Some things are simpler in the cloud, but many others are more complicated.

You enforce some good security practices because there is no way to NOT install the latest security patches. And you can quickly spin up an extra testing environment.

But unless you really have a highly variable load, or you are starting something new where you don’t have a clue how much power you’ll need, the cheapest option is to buy some hardware and put it in your server room.

The next time one of the vendors tells you how much you save by moving to the cloud, take a really good look at the calculation. I’ll be happy to help you. You will likely find out that there isn’t a business case for moving.

The convenience of Microsoft Azure come with some serious problems. It seemed like a good idea at the time to store your cloud service credentials in your on-premise identity management solution. With Microsoft Active Directory and Microsoft Azure, you got exactly that convenience.

The only problem is that when hackers get into your on-premise system, they own your cloud instances too. The US Cybersecurity and Infrastructure Security Agency (CISA) has issued an alert about SolarWinds hackers using privilege escalation to gain access to the Microsoft Active Directory Federated Services (ADFS) and then producing OAuth tokens to move laterally to your cloud instances.

The SolarWinds hack shows that having intruders in your system is the new normal. You need to compartmentalize access, and storing all your access rights in one central place is a very dangerous convenience.
