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

Infrastrucure as a Service vs

Database Platform as a Service

The buzzword for PaaS offerings for databases is….

DBPaaSWhich 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 flexiblity

• 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 uprades)

• 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

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?

YOU WILL BE REQUIRED TO ADJUST YOUR CHANGE MANAGEMENT PROCESSES AND DOCUMENTATION

Cloud Databases Are Administered Differently

than On-Premises Systems

Greater Impact DBPaaS – Less Impact IaaS

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

documentation here…

Questions to Create Your Cloud Architecture Strategy1. What is your cloud strategy?

• Testing the waters

• Choose between cloud and on-premises for best fit

• Intend to have a strong cloud presence

• Cloud first

2. What cloud benefits do you want to leverage?

• Reduce hardware/software costs

• Reduce human support costs

• Focus on business not system support

• Improve performance and availability

• Increase flexibility and agility

• Leverage complex architectures

3. What is your experience level with cloud systems?

4. How big of an impact (change management, training,

polices/procedures, roles/responsibilites) on your IT shop are

you willing to incur?

5. What application development platforms do you use?

6. How much control do you want to relinquish and how much

responsibility for your systems are you comfortable sharing?

7. What on-premises software tools do you use?

8. Is your data controlled by internal, industry-specific or

governmental regulatory requirements?

9. What auditing requirements are you required to meet?

10. Do you standardize on one DB or support multiple?

11. One provider or are you comfortable with multiple?

12. Do you intend to migrate DB, Apps or both?

13. What amount of DB and App changes are you willing to make

to migrate the system to the cloud?

14. What are your DR requirements?

15. What is your budget?

• Retrain staff, organizational role and unit changes

• Changes to process and documentation

• Changes for application rewrites, cloud data transfers, on-

premesis/cloud DB feature mismatch

Selecting Databases For Migration

1. Database importance

2. Database usage (customer facing, LOB, back office)

3. Frequency of application development activity

4. Frequency of database schema changes

5. Dependency and interaction with other systems

• Flat file loads

• Sends data to/receives data from other systems

• Data used to refresh other systems

• DB links used to access other databases

6. What level of modifications are you comfortable with?

• Limited changes

• Changes to APIs, connection mechanisms

• Total application rewrite to leverage new technologies

7. What on-premesis software tools interact with DB?

• Monitoring, application development, security

8. Performance requirements

• Stable workloads or spikes/seasonal peaks?

9. Monitoring requirements

10. Is data controlled by internal, industry-specific or

governmental regulatory requirements?

11. What auditing requirements are you required to meet?

12. What is the database footprint and workloads?

• Disk storage

• Concurrent users

• CPU and memory consumption

• I/O

13. High availability requirements

14. Backup requirements (frequency, # historical copies)

15. Disaster recovery requirements

The more interaction the DB has with on-premises systems, the more complicated support becomes

Most of the IT community is still concerned about

Cloud Security

As a database services provider, we can secure database on the cloud just as effectively as on-premises

We work customers to ensure they also secure input and output files related to database operation

The 3 BIG Players for

IaaS and DBPaaS

IaaS Offering is called Amazon EC2

Provides BOTH IaaS and DBPaaS

DBPaaS Offering is called Amazon RDS

You can run any software you want on IaaS. You install your OS and DB of choice – just like on-premises

Amazon not only provides the server, it has a very robust offering which allows you to build your entire application on Amazon. It is viewed to be more friendly with Unix/Linux and non Msoft DBs than Azure

Amazon has no on-premises offerings

This is a true DBPaaS offering. You rent the hardware, OS and your database of choice

Amazon RDS offers following DBs: SQL

Server, Oracle, MySQL, MariaDB and PostgreSQL

They also have their own DBPaaS databases: Aurora (MySQL), DynamoDB (NoSQL), Redshift (Data Warehouse) and Redis (In-Memory).

Provides more DB choices than Oracle and Msoft

Strengths Weaknesses

• Most mature provider of cloud services

• HUGE customer base – several times larger than

other vendors combined

• Large investment in infrastructure and innovation

• Robust provisioning and administration tools

• Lots of third-party tools, applications, service

providers

• Able to build entire application

• Breadth of architectures and environments

• Breadth of database products

• RDS – Oracle, SQL Server, MySQL…

• Aurora, Redshift, DynamoDB

• CLOUD ONLY

• Customer support gets mixed reviews

• Confusing array of options, features and

settings

• Amazon databases (Aurora, DyanamoDB)

features and functionality limited when

compared to Microsoft and Oracle

• Complex pricing

IaaS Offering is called Microsoft AZURE


Primary DBPaaS Offering is called Microsoft SQL AZURE

You can run any software you want on IaaS, including Azure IaaS. You can run any database - PostgreSQL, MySQL, DB2, Oracle and SQL Server. You install the databases on Azure like you would on-premises

Azure allows you to build your entire application. Traditional Ford vs Chevy as some think it is geared towards Msoft products. Not as friendly with Unix/Linux and non Msoft databases (Oracle, MySQL, PostgreSQL

This is a true DBPaaS offering. You rent the hardware, OS and SQL Server Database.

Microsoft also offers SQL Data Warehouse, DocumentDB (competes with MongoDB), Table Storage (key-value NoSQL) and Redis (in-memory)


• HYBRID CLOUDS

• Customer loyalty

• Huge customer base

• Large investment in infrastructure and innovation

• Environment rivals Amazon in features and functionality

• Database features and functionality

• Large number of security certifications

• Able to build entire application

• Pricing is simpler – when compared to Amazon

• Multi-product support

• Later to market than Amazon

• Focused on the Microsoft tech stack

• Running non-Microsoft DBs in Azure cloud services

can be challenging

• Limited product offerings available

• Support has received mixed reviews

IaaS Offering is calledOracle Cloud Infrastructure as a Service


DBPaaS Offering is called Oracle Database Cloud Service

You can run any software you want on IaaS environments. You install your OS and DB of choice – just like on-premises

BUT, since Oracle’s “claim to fame” and primary focus is databases (Oracle, MySQL) it isn’t as popular with customers running non Oracle products

This is a true DBPaaS offering. You rent the hardware, OS and database

Oracle provides DBPaaS for Oracle, MySQL, and Oracle NoSQL

Oracle offers a lot of flexibility on “who does what” for its DBPaaS offerings. You can choose to administer more of the environment


• HYBRID CLOUDS

• Service fees are very competitive

• Oracle Ravello (Lift and Shift VMWare and KVM)

• Customer loyalty

• Huge customer base

• Database features and functionality

• Customers have own Virtual Private Networks

• Firmly committed to cloud - Oracle pretty much “declared war”

against Amazon

• Same vendor that eclipsed the entrenched leader – IBM

DB2

• Deep pockets for building and acquisitions (Logfire,

Netsuite, Opower, Crosswise, AddThis)

• Strong focus on cloud migration services

• Entered later than both Amazon and Microsoft

• Architecture and offering still maturing

• Limited product offerings available

• Predatory licensing practices

• Cloud licensing is confusing (no change here)

Oracle Corporation Value Proposition

Oracle Bare Metal Cloud Services combine the elasticity and utility of public cloud with the granular control, security, and predictability of on-premises infrastructure to deliver

high-performance, high availability and cost-effective infrastructure services

• Dedicated hardware, single-tenant cloud service

• Your hardware to use as you wish

• Just like on-premises

• Pay as you go with elastic capabilities

• NO vendor software installed

• Offers traditional multi-tenant and Bare Metal

• Architecture and offering still maturing
