The rapid growth of cloud offerings are providing organizations with cost effective alternatives to on-premises systems. When calculating TCO and return on their cloud investment, savvy decision makers must also factor in costs that include staff training, new organizational roles and responsibilities, policy and procedure changes, modifications to application design, build and change management processes as well as the impact cloud applications will have on existing support toolsets. The last slide includes a link to the YouTube Webinar of this presentation.

3. There are Many Different Cloud DBMS Offerings and
Pricing Models

4. Cloud DBs are Architectures - Not Products
Offerings Range from Simple to Rocket Science
Cloud DBs Impact on Support > What Most Think
Not all DB Apps are “Cloud Friendly”

5. Different Types of
Cloud Platforms
On-Premises vs
IaaS and PaaS
On-Premises
• Server is onsite at your physical
plant
• You buy it and provide server
room, power, air, connectivity…
• YOU support all hardware
• YOU support all software from
OS up, including database
IaaS – Infrastructure as a Service
• Server is hosted by a provider
• You rent their hardware
• They provide server room, power,
air, connectivity….
• PROVIDER supports hardware
• YOU provide and support all software
from OS up, including database
PaaS – Platform as a Service
• Server is hosted by a provider
• You rent their hardware
• They provide server room, air,
connectivity….
• PROVIDER supports hardware
• YOU RENT the OS and database
• PROVIDER supports OS and
database software
Cloud

6. Infrastructure as a Service vs
Database Platform as a Service
The buzzword for PaaS
offerings for databases is….
DBPaaS
Which is PaaS for databases!
IaaS DBPaaS
• Have to purchase DB and OS licenses
• Able to install any software you choose – databases,
applications, third-party tools
• Easy to integrate your on-premises toolsets – monitoring,
security, application development…
• Allows you to maintain tight control of OS and DB
configuration
• Tight control over database utility execution – backups, index
maintenance
• Able to leverage cloud benefits that include elasticity,
scalability and flexibility
• Able to leverage features to reduce administrative time
(varies according to vendor and particular offering selected)
• Database products are limited by vendor offering
• Option of renting the DB and OS licenses from the provider
• Provider assumes greater administrative control over your
environment (software installation, DB and OS configuration,
patching, DB upgrades)
• WATCH VENDOR SCHEDULING WINDOWS
• Complex systems (HA, DR) are more easily configured
• Data geo-redundancy is often inherent to offering
• Provides backup and maintenance utility interfaces
• Pricing can be complex and is configured by selecting tiers
based on CPU, Memory, Disk utilization and performance
• If you are renting the software, when relationship is over, you
don’t own anything

7. Cloud Provider
• Offers DB and OS licenses as part of rental
• Robust compute and storage environment
• Operating system and database installed and
ready for use
• Configures DB (to an extent)
• Patches and upgrades OS and DB software
• Provides database maintenance utilities
(depending on cloud vendor and DB product)
• Includes administrative interfaces and monitoring
tools
• Provides problem analysis information
• Provides backups and backup configuration
interfaces
DBA
• Uses cloud DBMS to create databases
• Monitors resource usage (costs)
• Creates users
• Grants database security
• Creates data objects – tables, indexes,
views (there’s a bunch...)
• Loads data
• Works with developers
• Monitors database
• Tunes database parameters
• Troubleshoots database (with provider help
at times)
• Tunes SQL Statements
• Debugs performance problems (with
provider help at times)
• Configures backups, performs recoveries
• Configures HA systems
• Schedules maintenance, patches, upgrades
using vendor utilities
• And the list goes on……
The level of vendor support and self service
options available vary depending on the
cloud provider.
Everything the cloud provider doesn’t do...
So What do DBAs do on DBPaaS if the Cloud
Provider Takes Care of Database Software?

15. UNDERSTAND the cloud vendor’s pricing
models – they can be complex
MEASURE your current and estimate
future workloads
TAKE YOUR TIME during configuration
MONITOR consumption daily
BE PREPARED to quickly adjust your
configuration
SET UP billing alerts

Greater Impact DBPaaS – Less Impact IaaS

18. New Strategies and Standards Will Be
Created
• Objectives – Cloud only, cloud first, best fit, non-critical
• Budgetary – Strategy development, architecture selection, implementation, mature
system support, toolsets, training, existing datacenter, servers and related hardware
• Architecture – IaaS, DBPaaS, PaaS, SaaS, multi-cloud, hybrid
• Application – Replace, redevelop, optimize, minimal changes, new application
design
• Provider Sourcing and Selection – Features, pricing, maturity, lock-in, known vendor
• Organizational – Support units, new roles, hiring, training, governance
• Supporting Technologies – Application development languages, network, toolsets
• Regulatory Control – Internal, industry, governmental
Security, auditing, recovery, disaster recovery, toolsets, third-party applications,
application design, governance, change control, naming conventions, data transfers…
Strategies
Standards

19. Policies and Procedures Will Change
Security, disaster recovery, change management, monitoring,
problem resolution, job scheduling, administrative best practices,
repeatable processes, internal, industry specific, governmental
regulatory compliance, naming conventions – add required

Greater Impact DBPaaS – Less Impact IaaS

20. THERE IS A LEARNING CURVE THAT VARIES
ACCORDING TO VENDOR
Don’t Expect Your Staff to Become
Cloud DBMS Experts Overnight
Greater Impact DBPaaS – Less Impact IaaS

21. Cloud systems will require changes to your
support team’s organizational infrastructure.
DB and application architects play an
important role in the selection, configuration
and implementation of public cloud based
DBMS platforms.
Personnel must be dedicated to learn and
fully understand how to use the chosen
vendor’s configuration, provisioning and
administration services.
Cloud Database Systems Require New
Roles and Responsibilities

22. Cloud Development, DB Admin and Monitoring
Mechanisms Are Different Than On-Premises
YOU WILL NEED TO IDENTIFY WHICH OF YOUR EXISTING
TOOLSETS WORK – AND WHICH ONES DON'T
