This was one of those days I was waiting to happen. You might be wondering whats special? Yes, this day is very special because Rimma Nehme will be giving a keynote on Cloud Databases 101.
Rimma Nehme is one of those super smart people who works for Microsoft Gray Systems Lab along with the very special Dr David Dewit.
Day 2 started with a talk by Adam Jorgenson, PASS Exec Vice President of Finance.
Adam started talking on how PASS operate, from where money comes and how it’s used? The key thing to note is that PASS is in good financial state with good amount of rainy day fund.

Crowd was eagerly waiting for the keynote to start and Denise requested Rimma to take over the stage.
Rimma talked little about her and cracked some jokes about Dr. David Dewit. She added that she is a great fan of SQLServer/PASS community.
Rimma Nehme on stage giving Day 2 Keynote on Cloud Database 101
The agenda of the talk was based on :
- Why Cloud?
- What is a Cloud DB?
- How they are built?
- What is my role as a DBA?
When people like Dr. David Dewit or Rimma talk, they come with great simple slides with lot of information on them. They also tend to use real life analogy to explain things, which is really nice.
Here is an abstract of what Rimma talked:
Why cloud computing?
Why cloud? (Also known as 5th utility! )
Cloud is special because of its characteristics:
- On demand self-servicing.
- Location transparent resource pooling.
- Ubiquitous network access.
- Rapid elasticity.
- Measured service pay per use.
History of cloud :
1960’s (Super computers/Mainframe) ,1990(Sales force) ,2002(AWS), 2006(EC2), 2008 – present (Azure, Google Apps).
Where cloud lives: Data Centers(Of course !), and the move to the Next generation Data Centers.
Data center efficiency is measured in terms with PUE (Power Usage Effectiveness) :
PUE =
Total Facility Power / IT Equipment power.
Traditional PUE 2.0 vs Modular PUE 1.15(cooling 0%).
Microsoft Data-centers :
Over 100 DC in more than 40 countries, More than 1 Million Servers.
What is a Cloud DB
Platform As a Service, Infrastructure As a Service ,Software As a Service.
Pizza analogy of cloud:
What kind of cloud databases are out there: We have Managed RDBMS, Managed No SQL, Cloud Only DBaaS. Analytics as a Service, Object Store.
How they are build
Why Virtualization : Put under-utilized resources in use. With a drawback that direct access to resources will be lost.
Multi Tenancy : 4 common approaches. Private OS,Private Process/DB, Private Schema,Shared Schema.
Inside Azure SQL DB :
The concept is each account as 1 or more servers, each server has one or more databases, each database has one or more objects.
Everything designed with HA in mind.
Layers of abstraction : Client layer, services layer,platform later, infra layer.
Network topology :
MY role as a DBA
Last but not least Rimma talked about the role of DBA for Cloud.
Rimma wrapped up Cloud 101 talk by requesting Dr.Dewitt to join her on stage, and there was a standing ovation by the crowd.
Conclusion:
We #SQLFamily is expecting Rimma to be back next year to give a more in-depth talk on Cloud and we are looking forward to it.
Thanks for reading, and keep watching this space for more !
