Database for PostgreSQL Hyperscale

Microsoft Windows group chooses Azure Database for PostgreSQL
Hyperscale to scale its vast analytics and bring quality updates
to customers
Windows was looking for a cloud-based database
that could support the volume and velocity of
transactions in its diagnostic metrics that are
displayed on a real-time analytics dashboard which
drives the quality of customer experiences for
Windows updates.
By choosing PostgreSQL Hyperscale, ship/no-ship
decisions for Windows were made based on on-the-
fly analytics on billions of JSON events with sub-
second responses. Distributed SQL with Azure
Database for PostgreSQL continues to be a game
changer for Windows.
Real-time analytics: 95% queries execute in <4s
Response times: 75% of queries are <200ms
Query volume: >6m daily

Oracle to PostgreSQL | Why
• Over the last two years, we are seeing more and more customers moving away from hosting applications in
Oracle and migrate to other RDBMS datastores
• Not surprisingly, savings in licensing cost and support cost are some of the main triggers why customers are
moving away from Oracle
• PostgreSQL is an open platform with wide-ranging cost benefits compared to Oracle workloads
There are 5 reasons* we generally recommend PostgreSQL as the replacement database of Oracle:
I. PostgreSQL has gained credibility of enterprise ready and feature-rich database
II. Reduce total cost of ownership (TCO)
III. Shifting to adopt open source
IV. Similarities between Oracle and PostgreSQL to ease effort of migration
V. Azure offers elastic scaling and built-in HA with Azure Database for PostgreSQL
*See notes section for more detail on each reason

App is only 3rd party and can only run on Oracle on VM
App is 1st party, access to code and schema, willing to consider code
and driver updates and PostgreSQL – and get easier migration
App is 1st party, access to code schema, want to
standardize on SQL – with a somewhat harder
migration path

Configuration is based on a 4 socket, 32 core x86 processer
Oracle Cloud Service editions are based on virtual machines
• *Oracle licensing for Enterprise Edition is based on number of
processors which is derived by multiplying the number of cores by a
factor. In the case of this example it is 32 cores multiplied by .5 for
x86 resulting in 16 processors.
• **Annual maintenance and support for Oracle is 22% of the annual
license cost.
• ***Oracle standard terms for Enterprise Edition is 50% of list pricing
for 3 years. This example accounts for the 50% list pricing for 3 years
in the total.

Migration | Typical Cloud Pathways

Azure Database Migration Service

• Azure Database Migration Service는 다운타임을 최소화하면서 여러 데이터베이스 소스에서 Azure 데이터베이스 플랫폼
으로 원활하게 마이그레이션(온라인 마이그레이션) 할 수 있도록 설계된 관리형 서비스 입니다.
* 설치형을 이용하여 오프라인 마이그레이션 수행도 가능
• Data Migration Assistant tool을 사용하여 마이그레이션을 수행하기 전에 필요한 변경 사항을 안내 받고 권고 사항을
제공하는 평가 보고서를 생성할 수 있습니다.
• 필요한 작업을 수행하는 것은 사용자 중심이며, Azure Database Migration Service를 사용하여 온라인 마이그레이션을
수행하려면 프리미엄 가격 책정 계층에 따라 인스턴스를 만들어야 합니다.
