[Post Event] Codecamp Timisoara, October 14, 2017

In October 14 I attended to Codecamp Timisoara. It was a great experience, where I met great people from Timisoara and other cities around Romania.
At this conference I delivered a session about enterprise security and how you mitigate different security aspects when you want to migrate to Microsoft Azure. Below, you can find more information related to it.

Title: Enterprise security in Practice
Abstract: How does an enterprise looks like when you talk about security and cloud? Complicated, rigid and challenging to accept cloud based architectures. After working closely with security teams from different companies I identified different approaches and requirements that are standard for enterprises. In this session I want to discuss and share with you lessons learned on how we can map security requirements to Azure.

Migrating File Server (Share) to Azure

Let’s take a look on what are the current solution on Azure when we want to migrate our local file storage from on-premises to cloud.

On the current system, let us imagine that we have Windows File Server that it is used to share filers inside the company. The File Server is fully integrated with our Active Directory server and based on roles we allow/restrict access to different folders/files.

What we want to do?
We want to migrate to Azure this solution in such a way that we don’t need to manage the File Server machines and also to be able to have control on file sharing permissions using user roles (Active Directory integration).
Addition to this, we want to be able to attach as a shared folder or partition the shared content on the client machine.

Azure Files
An extremely powerful solution provided by Microsoft, which allow us to store our files in Azure and share them with others. The SMB protocol is fully supported, meaning that we can attach the shared on our client machin…

The real difference between an Azure VM with or without SSD

I want to talk about the real difference of an Azure VM with or without SSD. This is not a post with charts and artificial benchmarks; it is just a real story from the field.
One of my fellows from my work came at me complaining about a performance issue related to SQL Server. On an Azure VM with Linux they used to have an SQL Server instance. The DB storage size was not to complex and the DB size was acceptable.
Every few hours a job has to be executed on the database. There is a lot of data processing inside it and it usually takes around 1 hour. From duration perspective this is not acceptable, there is a clear NFR that request the task to be executed under 30 minutes.
An audit was done to the VM and database and it was pretty clear that there is a problem at read and write operations. Many actions were happening at that level, causing the memory and storage to be at high levels.
The DB specialists reviewed the database structure and the job. Unfortunately, the…

Using SQL security features to isolate sensitive data inside a PoC

When writing a PoC you need to keep it as simple as possible and prove that from a technology perspective the project vision is feasible and is the right one. One of the fundamentals rules of a PoC is that it needs to cover things that are not general truth (e.g. You don’t want to prove that ASP.NET MVC can render HTML or expose an REST API).
Keeping a PoC as simple as possible can become a problem when you want to use customer data not only mocks data. When you have customer sensitive information, which should not be visible even to the development team you might end up in a strange situation.
The problem is not related on how you can do this. The biggest problem is the effort that you need to invest to create the deployment scripts or the automation mechanism that would allow the customer to deploy the solution in an isolated environment, where development team would not have access. This effort might require extra development effort that you don’t want to include in a PoC.
It is cl…

Microsoft Ignite in a glance (Orladon, FL, 2017)

What a week! Last week of September was crazy from all the people that are working with Microsoft stack. The biggest Microsoft conference took place in Orlando, Florida. More than 25.000 people attended this year at Microsoft Ignite and as usually, it was an event will all the tickets sold out.

There were many announcement that makes Microsoft a strong player for today needs, but also there is a clear vision where they want to go. Not only this, but it seems that the road is already defined and clear.
The currents needs of the market are covered by Microsoft with Azure Stack, offering a good ground for hybrid solutions. Now we can use the core services of Microsoft Azure not only on Azure, but also on our on-premises infrastructure using Azure Stack. What is more interesting from devops and IT perspective is that you have the same experience, the same dashboard and you use the same scripts (no change is required).
Mixed reality and AI are now more closers to the fields. Many companies…

Why you should never put a junior in a team that is stressed and bad-mannered

It is nothing abnormal for a team to be stressed. During that times they might not have time for nothing else. The focus of the team is to deliver the business requirements in the IT solution. Unfortunately, this time periods can be longer than expected, even if we know that this is not good.
I saw teams being more than 18 months in a phase like this. After a while in this state, they don’t even realize that they are in this state and what is the impact and project and people level.
In this post, I will try to focus on the impact that such a phase can have at juniors and mid-levels in unhealthy teams.

When you are a junior you are in moment of you carrier when you want to learn. You know that you have things to learn, you are usually a fresh graduate with good theory knowledge and you want to put this in practice.
I like to compare smart juniors with birds that have big and powerful wings, but they don't know to fly very well yet. They can reach the sky and accomplish many thi…
