A look into CloudFormation resource import

Just before re:Invent, AWS launched a new feature for CloudFormation … Create Stack with existing resources! This gives a lot of options to start to manage existing resources as code, if they were created via GUI or CLI. Apart from that though, it now gives you the ability to move resources between stacks, rename stacks, etc.

There is a pretty good AWS blog, but there are some things the blog really didn’t cover too well.… [Keep reading] “A look into CloudFormation resource import”

Zero-Touch BitLocker with PowerShell

Context

The majority of IT engineers and architects traverse various forms of security on a daily basis ranging from our complex alphanumeric corporate logon passwords to the increasingly common MFA prompts on our mobiles. You could say that we have become experts in navigating modern security measures required to stay protected. But perhaps you’re not familiar in planning and rolling out that same security, at scale, to your organisation’s Windows laptops in the form of disk encryption.[Keep reading] “Zero-Touch BitLocker with PowerShell”

Diary of a re:Invent newbie

Wow, so the end of the year has quickly run up and I’ve finally found some time to write this up. While re:Invent was a few weeks ago, I took a few days vacation on my way home and then it’s been busy busy busy since. So, in the lead up, I’d watched the “How to re:Invent” videos and had advice from our senior AWS guy, Matt. I’d say the advice was pretty good and I made the most of my time.… [Keep reading] “Diary of a re:Invent newbie”

A tale of two products (don’t expect Dickens)

At Re:Invent and just after, AWS released several new products. Included in those were AWS FSx Windows and AWS Backup. Both of these products had a lot of interest for me, for various reasons, so I thought I’d give them a try. None of my experience was under work conditions, but the following are my experiences. Note: Both are only in a small number of regions, currently.

AWS FSx Windows

Pros:

  • Easy setup (by itself)
  • Fully compatible Windows file server
  • DFS support
  • Has backups
  • Works as expected

Cons:

  • Requires AWS Microsoft AD in each VPC
  • Can’t change file share size
  • Some features can only be changed from CLI
  • Throughput can only be changed through restore
  • Minimum share size is 300GB

First out of the box, and released at Re:Invent is AWS FSx Windows.… [Keep reading] “A tale of two products (don’t expect Dickens)”

Backups? Doesn’t Amazon handle that?

For many, the cloud is a magical place where servers just appear and your cloud provider looks after everything, or, if they at least have a concept of the servers, they just assume that the provider will also back them up. Lots of people never bothered to think about protection in a VMware environment, so why start now?

Unfortunately, while your cloud provider probably supplies the tools, you still need to do the configuration and management.… [Keep reading] “Backups? Doesn’t Amazon handle that?”

The Present [and Future] Landscape of Data Migrations

A rite of passage for the majority of us in the tech consultancy world is being a part of a medium to large scale data migration at some stage in our careers. No, I don’t mean dragging files from a PC to a USB drive, though this may have very well factored into the equation for some us. What I’m referencing is a planned piece of work where the objective is to move an entire data set from a legacy storage system to a target storage.… [Keep reading] “The Present [and Future] Landscape of Data Migrations”

Querying against an Azure SQL Database using Azure Automation Part 1

What if you wanted to leverage Azure automation to analyse database entries and send some statistics or even reports on a daily or weekly basis?
Well why would you want to do that?

  • On demand compute:
    • You may not have access to a physical server. Or your computer isn’t powerful enough to handle huge data processing. Or you would definitely do not want to wait in the office for the task to complete before leaving on a Friday evening.
