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. 3. There are Many Different Cloud DBMS Offerings and Pricing Models
  4. 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. 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. 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. 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?

  14. 14. Amazon and Azure Cloud Advisors Recommendations: • Cost reduction • Performance • Security • Availability
  15. 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 Cloud DBMS Charges - Don’t Get Surprised!
  16. 16. Amazon Oracle Database Configuration
  17. 17. 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
  18. 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. 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 documentation here… Greater Impact DBPaaS – Less Impact IaaS
  20. 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. 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. 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
  23. 23. Coding, Administration and Testing 100% App Code Transportability Database Features Cloud DBMS Product Features and Functionality Don’t Always Match On-Premises Counterparts

  26. 26. THE HARDER IT IS TO SWITCH VENDORS The More You Have to Tailor Your Database/Application to Work With Your Chosen Cloud Architecture
  27. 27. The more interaction the DB has with on-premises systems, the more complicated support becomes Flat File Loads Input from other DB Apps Large Output Files Sent to Other Systems Output to Other DB Apps Data Clones and Refreshes NO DATABASE IS AN ISLAND New Data Transfer Mechanisms New Data Transfer Procedures
  28. 28. CHOOSE THAT VENDOR WISELY You Will Share Responsibility with a Third Party Provider for the Security, Availability, Performance and Recoverability of Your DBMS
  29. 29. Questions to Create Your Cloud Architecture Strategy 1. 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/responsibilities) 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? • 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
