Microsoft Azure SQL Database – SQL Azure : The Good, The Bad and the Ugly. Pini Krisher DBA TL at etoro

Agenda: 10 minutes of basic introduction. 10 minutes of ways to work with SQL Azure 10 minutes of good 10 minutes of bad 10 minutes of Ugly 10 minutes of some conclusions.

Basic Introduction What is Cloud Computing. Types of Cloud Computing. Vendors DataBases on AZURE

What is the Cloud Computing? Pay as you go Scale – UP/DOWN/IN/OUT Backups Upgrades Access from any ware SLA Storage Types SAAS IAAS PAAS

Cloud is not 1 huge machine

Vendors AWS-Amazon Web Services Rackspace Google HP Cloud Dell Microsoft Azure Ect….

DATABASES on AZURE Windows Azure SQL Databases - PAAS SQL Server on VM - IAAS Windows Azure Storage\ DocumentDB - NoSQL

Ways to work with SQL Azure SQL Azure is PAAS! What is PAAS in DB world? Azure Portal * 2 Web portal SSMS PS

PAAS Microsoft Azure SQL Databases = SQL Azure

What is PAAS in DB world You can not connect to the server You can not manage hardware You can not control hardware No clusters etc.… So… what DBA’s can do? Nothing in infrastructure - there are 3 replicas… Applicative work: adding Indexes, short transaction etc.… Performance tuning High queries by CPU,IO etc.…

Azure Portal Create Server Create DB – 3 ways (from portal, ssms, vs2012) Location Tier Size – GB Security Basic monitoring (monitoring in other tools like Quest) Connection strings from the portal Backups to BLOB

Monitoring Tools Portals

Web protal Connect – silver light – to 1 DB or to server Run T-sql Basic monitoring Query plans Add indexes See DATA Change schema

SSMS All actions but backup

PS All actions

The Good

No OS No Upgrades Any One, Anywhere can query DB From Smartphone you can monitor Scale-Up DR VM - templates New features – looks at the blog (Auditing, Automation) …. Or not

The bad

No regular backups No read replica within the data center Features that are not supported Co administrator in Azure can change lots of things. Changes in Azure can bring your bill up – without changing anything. Fair share policy. Scale out only via code

And The Ugly

Federations is retired Not all T-sql supported (sequence) New feathers are slow - for example EE or backups only via PS. SLA – good but when you need Restart – you can not do it. Many small DB’s with better DTU – cost as 500 GB DB’s

conclusions

SO… When should we use SQL AS PAAS ? Simple and small DB’s The high point after IPO or Elections Reduce storage costs/IT costs No MSFT agreements When we need Unlimited resources Easy to manage (But risky) Hybrid – some on privet cloud and some on public. No Bottlenecks at IT, Finance ect.. conclusions

Usege logs Regular DB Lots of small DB’s Scale up – increase DB size Scale out – Shard Devops

Price ??? Pricing calculator
