[Post Event] ISTAConf 2017, Sofia

Just finished my session at ISTAConf 2017 and I realize that we are not only talking about NoSQL and migration  strategy, but we even doing that. I just met some great guys from Sofia that started to migrate their relational database to MongoDB. What was awesome that they have in plan a migration from on-premises to Azure in the next 3-6 months for their system, so Azure Cosmos DB is the perfect suite for them.

It is the 7 edition of ISTA Conference, that started in 2011. Last time when I was here was 2 years ago and in comparison with that times they grow a lot. Not only during the keynotes, but also during the sessions the rooms are full with people that are curious to find more about what are the current trends and what future is preparing for us. What I like at ISTA is the format of the conference. Even if there are more than 750 participants, they don't have more than 3 tracks. allowing them to keep the quality of session at a high level.

At this conference I talk about Azure…

[Post Event] Meetup in Sofia together with Bulgarian BI & .Net User Group, November 2017, Sofia

Last I had the great opportunity to be invited by the local user group from Sofia (Bulgarian BI & .Net (BI & .Net Geeks) UG) to talk about Azure and Security at one of their meetups. It was such a great experience, meeting smart people that are full with energy and open to new technologies and ideas.

You can find below slides and content related to my session. Title: "Azure 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." Slides:

[Post Event] ITDays 2017, Cluj-Napoca

This week it was the 5th edition of ITDays in Cluj-Napoca. This is a conference started small and become of the most important conferences in Cluj-napoca that take place in the second part of the year.
During the 2 days of the event there were more than 40 sessions delivered by around 40 speakers. Additional to this there were a lot of products and startups presentations that make us believe that there is something more than just code (smile). I had the opportunity to be invited as speaker at this conference where I talked about near-real time solutions that can be developed using Microsoft and Azure tools. More about my session can be found below:
Title: Near-real time reporting in Azure Abstract: One of the most common requirement on a projects nowadays is real time monitoring and reporting. Easy to say, expensive to implement and complex to maintain. In this session we'll take a look on the Azure Services that enable us to fulfil this requirements with minimal effort and with maxi…

[Post-Event] Codecamp 2017, Cluj-Napoca

This was the last Codecamp in Cluj-Napoca for 2017. With more than 1000 registered attendees and 50 speakers it was a great way to close the year. There were 10 tracks in parallel that made possible to have 70 sessions of 45 minutes in only one day.
I had the opportunity to deliver two sessions at this event, where I talks about how you need to mitigate security when you migrate from on-premises to Azure and Azure CosmosDB. Below you can find my session details and slides.

IoT Home Automation | (1) Initial Overview

After playing a while with different IoT devices, I decided that it is a perfect moment to start to do some automation inside the house. Nothing special or fancy, just small things that improve the quality of life and force me to work on some hardware devices also.

What I want to achieve?
There are three different system that I want to connect and to be able to remote control and automate.
Garage doors and gates – I want to be able from my mobile phone to open or close the gates. In this moment, I have a remote control that control them. However, in the future I do not want to use them anymore, I want to replace them with only one device – my phone.
Alarm control – Usually when you close or open the gates you also need to arm or disarm the house alarm. Why not integrate this inside one system that would be able to open the gates and disarm the alarm automatically.
Automatically water system – Even if we love plants and flowers, it is a nightmare in the morning to water 20 minutes all the …

Lift and Shift - cloud migration strategy

During discussion on different cloud projects I observed that people are using “Lift and Shift” terminology with multiple meanings. This can create confusion between different parties, especially when technical team from each team understand a different thing.

What is Lift and Shift?
Lift and Shift is a migration strategy that is based on the concept of replication 1 to 1 of the environment that exist on-premises inside cloud (Microsoft Azure). This involves the migration of all computation, storage and other services without replacing them with specific Azure services.

What is not Lift and Shift?
When you have a File Server system on the current infrastructure. Lift and Shift in this case shall not include replacing it with Azure Files. Involves just taking the File Servers instances from on-premises and putting them inside Azure VMs.

Another good example is when you migrate a web farm. If you decide to do just a Lift and Shift, than you should just spin Azure VMs where you would use A…
