TechEd 2013 - Day 2

By
Second day of TechEd 2013 has ended. For me, this day was full off interesting information related to SQL Server and Windows Sever. From my perspective, the most interesting sessions of the day where related to security. During this sessions I realize that we are extremely vulnerable to attaches, even if you change the server password every 4 hours. An attack can be made in 5 seconds – the same problem is on the Linux system, not only Windows.
Things that I consider interesting:

  • Foca – it is an interesting tool to discover what the public content that is listed by an internet endpoint. It will extract meta-information like the name of the users, machines, software version and so on. 
  • It is extremely easy to modify a worm or trojan to make it undetectable and for 100$ you can buy an application that give you the ability to “manage” the infected machine.   
  • You should NEVER have an async method that return void, except when you are working with event handler. If an exception occurs, the exception cannot be catch at the code level. Because of this you will have odd behaviors from time to time like: in Windows Phone this exception will disappear and in Windows 8 this error will cause the application to “die” immediately, without a notifications. Another problem with this kind of calls is when the actions end – because the system cannot tell you when the call end. In this cases you should return Task and not void.
  • If you want to hide the main menu from Visual Studio, that you could try Hide Main extension. Pressing ALT will show the menu back again.
  • When you have Visual Studio open, than ALT + F6 can help you to navigate between Visual Studio windos.
  • Don’t forget SHIFT+ALT will give you the ability to make multi-line editing.
  • If you are using SignalR and you need to create a small cluster and synchronize different servers with SignalR than Windows Azure Service Bus can be a solution for you. You need to write only one line of code to have Service Bus in the backplane.

That’s all for today, see you tomorrow.

How to audit an Azure Cosmos DB

By
In this post, we will talk about how we can audit an Azure Cosmos DB database. Before jumping into the problem let us define the business requirement: As an Administrator I want to be able to audit all changes that were done to specific collection inside my Azure Cosmos DB. The requirement is simple, but can be a little tricky to implement fully. First of all when you are using Azure Cosmos DB or any other storage solution there are 99% odds that you’ll have more than one system that writes data to it. This means that you have or not have control on the systems that are doing any create/update/delete operations. Solution 1: Diagnostic Logs Cosmos DB allows us activate diagnostics logs and stream the output a storage account for achieving to other systems like Event Hub or Log Analytics. This would allow us to have information related to who, when, what, response code and how the access operation to our Cosmos DB was done. Beside this there is a field that specifies what was th...

Why Database Modernization Matters for AI

By
  When companies transition to the cloud, they typically begin with applications and virtual machines, which is often the easier part of the process. The actual complexity arises later when databases are moved. To save time and effort, cloud adoption is more of a cloud migration in an IaaS manner, fulfilling current, but not future needs. Even organisations that are already in the cloud find that their databases, although “migrated,” are not genuinely modernised. This disparity becomes particularly evident when they begin to explore AI technologies. Understanding Modernisation Beyond Migration Database modernisation is distinct from merely relocating an outdated database to Azure. It's about making your data layer ready for future needs, like automation, real-time analytics, and AI capabilities. AI needs high throughput, which can be achieved using native DB cloud capabilities. When your database runs in a traditional setup (even hosted in the cloud), in that case, you will enc...

Cloud Myths: Migrating to the cloud is quick and easy (Pill 2 of 5 / Cloud Pills)

By
The idea that migration to the cloud is simple, straightforward and rapid is a wrong assumption. It’s a common misconception of business stakeholders that generates delays, budget overruns and technical dept. A migration requires laborious planning, technical expertise and a rigorous process.  Migrations, especially cloud migrations, are not one-size-fits-all journeys. One of the most critical steps is under evaluation, under budget and under consideration. The evaluation phase, where existing infrastructure, applications, database, network and the end-to-end estate are evaluated and mapped to a cloud strategy, is crucial to ensure the success of cloud migration. Additional factors such as security, compliance, and system dependencies increase the complexity of cloud migration.  A misconception regarding lift-and-shits is that they are fast and cheap. Moving applications to the cloud without changes does not provide the capability to optimise costs and performance, leading to ...
