The Cloud usage grows in the last years rapidly, but in many customer environments we had servers and applications they can´t migrate to the cloud about different reasons. There are many reasons why applications can not migrated to the cloud e.g. data regulations, connections and latency challenges and more. On the other hand customers whish to use different cloud providers. In summary the hybrid cloud is one of the most use cases in many customer environments. Microsoft released Azure Arc as a solution for hybrid cloud environments. Azure Arc was announced as public preview at Ignite 2019 and going GA on Ignite 2020.
In this article I will cover how connect Windows VMs to Azure Arc.
Azure Arc in General
Azure Arc is a solution to extend the Azure management capabilitites to services outside of Azure. This gives the possibilites to manage different services, in different environments from one central place with same capabilities across different services layers.
Microsoft release the first version for Server management and has since expanded the range of functions over Dataservices, Kubernetes and new since some days Azure applications.
The recording of the session is now available on Youtube. I have added the link at the end of the article.
I am glad to announce that I was invited as a speaker to the Cloudeight conference. This is the 3rd edition of this conference and the conference is grown to a really big conference with a lots of great speakers and sessions. The conference itself was founded by Drago Petrovic as a free community driven conference.
I am very exited to deliver a session on 7 tips you need to know to use Azure File Sync perfectly. Azure File Sync is a perfect service to sync file servers across enterprise boundaries through a central Azure Fileshare. In this session, I will share the best practices to use Azure File Sync perfectly based on my real-world experience. I will cover the following topics:
Over the past few months, I have conducted many customer workshops, designed and implemented Landing Zones, and migrated or placed VMs into Azure. One of the most common customer questions has been about best practices for Azure VMs to maximize performance and efficiency, minimize costs, increase security, and reduce management overhead. This article is based on my real-world experience and recommendations based on several Azure projects.
In the past I do a lot of Azure Governance workshop and one interesting topic is how to handle the Break Glass Account. Before we going deeper, first we take a look was is the Break Glass Account. For each Administrator role in Azure or Office365 is it best practice to use MFA to secure the account and get a better security for the Tenant. To realize this, normally we use Conditional Access and create a rule, that every Admin require MFA for login. But what can we do, when:
the MFA service is down
we create a Conditinal Access that with a wrong rule set and lost sign-in access
we do not regulary update our control list and the admin account goes lost
For this cases we need a Break glass account, an additional account with a high security password, to enter the Tenant in an emergeny case. For this account, there are some recommendations:
only use a generic account
create a complex password with more than 16 characters
for compliance reason divide the password into two parts
save each part in a different location
create a security group that contains the break glass accounts
create two break glass accounts with no standard username like breakglass@ or emergency
use the Tenant name for the account
do not use a custom domain name
in futher it will be possible to use FIDO2 security key for break glass (right now is in preview and not recommended for such critical scenario)
Now we can discuss in some ways a security gap – a service account with Global admin rights that do not require MFA for login. Now you see, why it is so important to monitor this accounts and get notified when they will be used for login.
In the past I have taken several Azure exams, and yesterday I took the Azure Security exam Az-500. I am really glad that I passed the exam. In this article I will give you a brief overview of the topics I saw in the exam and what materials I used to prepare for the exam. I can say directly that the best way to succeed in the exam is practice.
SIEM (Security Information and Event Management) Systeme sind in den meisten Unternehmen bereits für Security Zwecke im Einsatz. Eine rein Cloudbasierte Variante hat Microsoft vor ca. 6 Monaten als Public Preview unter den Namen Azure Sentinel vorgestellt. Azure Sentinel hat unzählige Konnektoren und basiert im Backend auf Log Analytics. Seit heute ist Azure Sentinal allgemein verfügbar und Microsoft hat die Preise und die SLA veröffentlicht. Diese Artikel gibt einen Überblick über die enthaltenen Services, welche Preismodelle vorhanden und welche Features kostenfrei verfügbar sind.
Gestern Vormittag durfte ich zum ersten Mal auf der Cloud and Datacenter Conference (CDC-Germany) in Hanau eine Session halten. Die CDC ist eine der wenigen Konferenzen in Deutschland, die den Fokus auf On-Prem und Hybrid Cloud Szenarien legt und dadurch viele Kunden erreicht. Carsten und seine Frau haben eine tolle Konferenz gegründet, die jedes Jahr mehr Teilnehmer zählt. Dies liegt auch an den vielen hochkarätigen Sprechern, die Carsten für die Konferenz gewinnt.
