Disaster Recovery – how to recover your application if a disaster occurs. Disaster Recovery is part of what we call “resilience” today. Resilience is the how to ensure that our applications are reliable or recoverable. This is a different approach and view of the more legacy “disaster recovery” environment where a cold (or warm) standby […]
As a continuation of my AZGateway migration scripts I entered the scripting world again for the migration of VMs. As anything worth doing is worth doing twice I actually wrote the entire script and then found out the Microsoft Azure SAP team already had something lined up. While their script did migrate VM’s there were […]
As promised, I would cover Availability Zones a bit more in the next few posts. If your Azure region supports Availability Zones you probably want to use them. Yes the services are a bit more expensive but you gain a higher SLA and the ability to adopt an active-active infrastructure. This active-active infrastructure usually starts […]
Microsoft is working hard to make “Availability Zones” available for most of their primary Azure regions. What is an Availability Zone will be covered later in another blog post, including why you should use it, what advantages it brings and more importantly (as most of the previous is covered by Microsoft documentation) – how do […]
So, this topic might be a bit too short for you, and I’m sure your BGP filters in your SRX are way more advanced. But for the simpler people like me that just need to get something done; this one is for you. When I did the AnyCast DNS setup using BGP at home and […]
Doing Active Directory Migrations is always tricky, certainly on applications. I’ve recently came across an application that performs an (uche 200x) based simple-LDAP bind to validate credentials. Now, we could rewrite the entire application to use SAML, OpenIDConect, Kerberos, Headers or whatever. But that’s not always possible. But how do we manage applications that do […]
I wanted to write this post on when to decide on a new subscription or not.. but then it turned to security – which – as many of you know is close to me as well.. so while the beginning of this post is about “when to choose a new Azure subscription” the conclusion is: […]
When deploying Active Directory, it has been a tradition to set the DNS IP addresses on clients to match the nearest Domain Controller to the clients. This means that every DHCP scope in the organization has to have different IP addresses for the name servers and administrators have to manually ensure everything is configured correctly. […]
I thought to start the new year with acronyms. This post will be about deploying Microsoft SQL containers inside Azure Kubernetes Services running on top of Azure Stack HCI. Microsoft SQL has been around for quite some time but deploying it as a container in Kubernetes is quite new for administrators. It does bring benefits […]
