AWS CloudFormation EC2 Win AD servers


  1. EC2 instances must be automatically added to Active Directory (AD) on provisioning and removed form AD on termination
  2. Each EC2 instance must have 3 private IP addresses (required for MS SQL Always-On) assigned by DHCP
  3. NLB must be used to expose MS SQL Always-On Listener because it’s faster than changing CNAME value
  4. Dedicated ASG to keep each instance fault tolerant
  5. Dedicated data disks which are re-attached to new instance in ASG with the same disk letters

Cloud agnostic approach with Terraform

If you’ve been working with both AWS and Azure you should have noticed that each of them has some advantages.

Tools like Terraform might be very helpful if you’re not familiar with both CloudFormation and Azure RM.

However don’t consider Terraform as a nonpareil (this is not true at all), it is simple tool for simple tasks.

So in this  post I’ll tell you about Terraform terms and concepts and show example with AWS & Azure.

For a bit more complicated infrastructure you’ll have to use CloudFormation and Azure RM

How to query a few MS SQL databases on different servers from single script

It’s quite common practice to keep databases on dedicated servers nowdays, especially if you use AWS RDS or Azure.

Relational databases performance is always painful and you might want to split data across at least a few databases. But if data is divided you still to have to do some logical operations across the whole amount and it’s quite simple, so let me show how it can be done using bot SQL Server Management Studio and CLI.

Install single tableau server in custom AWS VPC

If you interested in Tableau installation on AWS you should have a look at CloudFormation templates from Tableau.

Single server installation suits well for trial, but it has a number of limitations including link to default VPC. But what if you want to deploy it in dedicated VPC or you don’t have default one?

Not a big deal, I’ve updated template and you can use it:

Install Microsoft sqlcmd command-line tools on AWS Linux

If you have MS SQL server in your environment and have to do some actions (execute migrations, change data, etc.) with it during your CI/CD it might be quite inconvenient to use Windows machine.

Fortunately we have sqlcmd for Linux, and Microsoft provides some instructions for popular Linux distributions –¬†

But what if you have AWS Linux? If you try to use instructions from MS you will fail and there’s not much information across the Internet about this topic. The only useful link is here.

Since my env is highly automated I decided to create simple script to install sqlcmd on AWS Linux and share it with you:

Get active Jira sprint name from CLI

When you do some CI/CD jobs you might want to mark some builds with name of the current (active) Jira sprint.

We have a dozen components in the project with dedicated Jira projects and sprint names are like “Backend sprint 12”, so you probably don’t want to add useless information to the build and need only number to identify build.

Jira has a nice REST, so you can get what you want in a very simple way:
