Secure Azure Virtual Network using Network Security Groups

The way that Network Virtualization is implemented in Hyper-V and subsequently in Microsoft Azure IaaS, enables explicitly the Routing between Virtual Subnets. This is the reason why the traffic between Virtual Subnets, that are part of the same Virtual Network, is unrestricted unless we have applied Network Security Groups. Network Security Groups Is a way to control traffic between Virtual Subnets of an Azure Virtual Network as well as the Internet. Moreover, Network Security Groups provide s

Running pfSense as an Azure IaaS Virtual Machine

A client of mine has asked me if it would be possible to run pfSense as a Microsoft Azure IaaS Virtual Machine. pfSense® software is a free, open source customized distribution of FreeBSD, specifically tailored for use as a firewall and router that is entirely managed via web interface. At that time, I had in mind that running FreeBSD 10 under Hyper-V and in Microsoft Azure, is something that can be done. So, I decided to build a deployment as a Proof of Concept and to write a blog post about t

Multi Factor Authentication δυνατότητες στο Office 365

Πρόσφατα προστέθηκε η δυνατότητα του Multi Factor Authentication (MFA) για όλους τους χρήστες του Office 365. Για τους χρήστες με δικαιώματα διαχειριστή της συνδρομής στο Office 365, η δυνατότητα αυτή του MFA ήταν διαθέσιμη και σχεδόν υποχρεωτική από τον Ιούνιο του 2013. Τι είναι όμως η δυνατότητα του Multi Factor Authentication και γιατί τον όρο MFA τον ακούμε όλο και συχνότερα στις μέρες μας; Multi Factor Authentication ή Two Factor Authentication είναι η ταυτοποίηση εκείνη στην οποία χρησιμ

IT PRO|DEV Connections 2020 is back! #itprodevgreece

The greatest, community driven, technical event in Greece for IT Professionals and Developers is back! It’s been long time since the last ITPRO|DEV Connections event  took place. There are a few reasons for that, but this does not matter anymore as we proudly bring it back to life and this time in virtual form! This event is community driven, and this year the number of the communities that take part are bigger than ever before. This signifies great momentum and deep commitment from the commun

Integrate Microsoft Azure Active Directory tenant with Office 365

One question that is coming up too often, at least at TecEd Europe 2014, is if it’s possible to integrate an Azure AD that you got when you signed up to Office 365 with the one you have got when you subscribed to Microsoft Azure. The short answer is yes, it is possible and if you want to learn how this integration happens, then keep reading! This scenario means that there are two separate directories. The first one was created when you setup your Office 365 Subscription, while the second one ca

Create a Virtual Machine with Multiple NICs in Azure IaaS

Every time I present a session about Microsoft Azure IaaS, the most common question is about Virtual Machines’ capability of getting more than one Virtual Network Interface (vNIC). At TechEd Europe 2014, Microsoft announced support for multiple Network Interfaces (vNICs) in Azure VMs, as well as other additions to Azure Virtual Networks like Network Security Groups.   Moreover, the capability of adding more than one vNIC to a Virtual Machine will enable Virtual Appliances scenarios like Firewa

Create a fully private AKS infrastructure with Bicep #AKS #biceplang

Intro In this blog post I will describe a way to implement an architecture that includes a private Azure Kubernetes Service (AKS) Cluster by using Bicep, a declarative language for describing and deploying Azure resources. According to project’s page on GitHub, Bicep is a Domain Specific Language (DSL) for deploying Azure resources declaratively and It aims to drastically simplify the authoring experience with a cleaner syntax, improved type safety, and better support for modularity and

Configuring a Static Internal IP Address (DIP) for a VM in Azure VNET

Αυτό που ήταν γνωστό μέχρι τώρα και τονιζόταν ιδιαιτέρως, ήταν να μην αποδίδεται για οποιοδήποτε λόγο Static IP address στα Virtual Machines του Microsoft Azure IaaS. Ακόμη και εάν τα VMs προορίζονταν για Domain Controllers ή για DNS Servers. Όσοι μάλιστα το είχαν προσπαθήσει είδαν τα VMs που είχαν δημιουργήσει να εξαφανίζονται, ξαφνικά, από την κονσόλα διαχείρισης. Με τις τελευταίες όμως βελτιώσεις που έγιναν στις υπηρεσίες του Azure IaaS (Μάιος 2014), στην περίπτωση που το VM συνδέεται σε κά
