IaaS vs DBaaS
Infrastructure-as-a-Service
• Some conversion costs
• Have to purchase DB licenses, BYOL/rent OS license options
• 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 and OS utility execution – backups,
index maintenance, patching, upgrades
• 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-as-a-Service
• Database products are limited by vendor offering
• Rental fees include DB and OS
• Provider assumes greater administrative control over your
environment (software installation, DB and OS configuration,
patching, DB upgrades)
• Complex systems (HA, DR) are more easily configured
• Data geo-redundancy is often inherent to offering
• Provides backup and maintenance utility automations
• Pricing can be complex and is configured by selecting tiers
based on CPU, memory, I/O, and disk consumption
• If you are renting the software, when relationship is over, you
don’t own anything

Creating Your Cloud Architecture Strategy
• 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
• 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
• Faster application time-to-market
• Quickly leverage complex architectures
• What is your experience level with cloud systems?
• How big of an impact (change management, training,
polices/procedures, roles/responsibilities) on your IT shop are
you willing to incur?
• What application development platforms do you use?
• How much control do you want to relinquish and how much
responsibility for your systems are you comfortable sharing?
• What on-premises software tools do you use?
• Is your data controlled by internal, industry-specific or
governmental regulatory requirements?
• How sensitive is the data you are storing?
• What auditing requirements are you required to meet?
• Do you standardize on one DB vendor or support multiple?
• Do you want to consolidate with one cloud provider or are you
comfortable with multiple?
• Do you intend to migrate DB, apps or both?
• What amount of DB and app changes are you willing to make
to migrate the system to the cloud?
• What is your budget?
• Retrain staff, organizational role and unit changes
• Changes to process and documentation
• Changes for application rewrites, cloud data transfers, on-
premises/cloud DB feature mismatch
• What are your HA and DR requirements?

Single vs Multi-Tenant IaaS
Multi-Tenant IaaS
• Less expensive than Single-Tenant IaaS
• Cloud provider assumes greater degree of ownership
• Share computing resources with other tenants
• Often provides more automations than single tenant
Single Tenant IaaS
• More expensive than Multi-Tenant IaaS
• Customer assumes greater degree of ownership
• Cloud provider assigns dedication resources to single tenant
• Good for clients that adhere to strict regulatory compliance
• Easier to transfer on-premises licenses
• Still able to easily scale resource allocations
• Predictable performance
