- 11. April 2-6, 2017 in Las Vegas, NV USA #C17LV Network Virtualization • Splits up available network bandwidth • Distributes according to needs • Similar to partitioning is to DBAs
- 12. April 2-6, 2017 in Las Vegas, NV USA #C17LV Storage/Server Virtualization • Storage • Pools physical storage from multiple storage devices • Appears as one device • Single console manages all • Common in SAN environments • Server • Masks server resources • Allows for resource sharing
- 13. April 2-6, 2017 in Las Vegas, NV USA #C17LV What is a Snapshot?

- 17. April 2-6, 2017 in Las Vegas, NV USA #C17LV Each Database Is Independent of the Source
- 18. April 2-6, 2017 in Las Vegas, NV USA #C17LV Types of Snapshots • Hardware • VM level, not application or software “aware”. • Older VM technology required the virtual image to be in a static or closed state before creating a snapshot. • Some hardware VM technology is software “aware” or compliant. • Software Consistent • Creates a static or consistent snapshot of software or applications. • Similar to RMAN putting tablespaces in backup mode, tracks changes and block level for both physical and logical consistency. • Is required for complex code and interactive products.
- 19. April 2-6, 2017 in Las Vegas, NV USA #C17LV Storage Vendors Examples • Oracle ZFS • NetApp • EMC XtremIO Many require additional software investment to be application or database “aware”.

- 24. April 2-6, 2017 in Las Vegas, NV USA #C17LV Copy Data Management, (CDM) • Confusion- New Term • Creates physical copies of images with clones • Tracks copies of physical clones • Manages clones/thin clones • Virtualizes non-production clones • Hybrid management mixed in for coolness • Types • Enterprise • Integrated • DevOps • Agile
- 25. April 2-6, 2017 in Las Vegas, NV USA #C17LV What CDM IS NOT… • Simply copying databases/applications/files on-premise or in the cloud. • Transportable tablespace, datapump and other archaic processes to migrate data. • A non-repeatable process, (i.e. only works once or in a vendor’s lab.) • Cloning or copying, but leaving data unusable, (i.e. snapshot technology that isn’t application or database aware.)

- 35. April 2-6, 2017 in Las Vegas, NV USA #C17LV Do I Have to Mask Data? Nah…. • As of April, 2014, Yes- at least in Europe. • ARTICLE 29 DATA PROTECTION for EU • HIPAA • The Health Insurance Portability and Accountability Act of 1996 (HIPAA) • PCI • Payment Card Industry Standards, 2016, Updated • PII • Personably Identifiable Information, GSA Rules • SOX • Sarbanes-Oxley Act of 2002
- 36. April 2-6, 2017 in Las Vegas, NV USA #C17LV Masking in the Picture As 80% of data in a company are copies, then 80% of data won’t be subject to security like a production environment. Securing this data is not just a priority, but in many cases, subject to legal ramifications, (i.e. PCI/PII) • Masking shouldn’t be reversible • The masked data should be representative of the original data type to ensure performance is consistent. • Referential Integrity should be maintained as part of the masking process. • Masking should be a simple, repeatable process with a user interface that ensures it is simple.

- 38. April 2-6, 2017 in Las Vegas, NV USA #C17LV Summary • Virtualization is a large landscape. • Cloud is an required part of the equation. • Products cover many areas- hardware, database, network and application. • Some focus on solutions for specific challenges in IT. • Terms like Copy Data Management can be confusing. • Virtualization is a very important part of the product offering. • Automation and User Interface is almost as important. • Virtualization can mean big saving when discussing the cloud. • No matter what, you should be looking at virtualizing.

Editor's Notes
- You may be saying- I thought virtualization was going away with cloud adoption?? The opposite- what most will find as the monthly bills come in, is that virtualizing what is out on the cloud or even better, what is migrating to the cloud before a lift and shift is the key to success and incredible savings.
- Mark Hurd is quoted as stating by 2025, 80% of businesses will no longer have a data center. That would result in 100% cloud adoption for those companies. With cloud adoption, just as cross platform, we will have cross-cloud. Hybrid has a new meaning, too. Hybrid is now multiple cloud vendors vs. on-premise/cloud.
- 52% growth in the next two years. This will replace physical machines in data centers and most lump virtualized hosts, but don’t realize the power that virtualization brings to cloud migrations. With half their capacity residing in the cloud in two years, what does this mean for physical cloning of all that data to the cloud? Even if ½ that is retained to private clouds, the companies are still charged for data in flight, as well as data stored in the cloud.
- Amazon and Azure own this race, but a price war could shake up the future of which cloud our data resides. Almost 70% of the market is owned by Amazon and Microsoft
- An overall trend in companies that includes autonomic computing, where the IT environment will be able to manage itself based on perceived activity, and resource shared computing, in which computer processing power is utilized and/or paid for only as needed. The usual goal of virtualization is to centralize administrative tasks while improving scalability and work loads. Understanding the power of virtualization when it comes to cloud adoption is key to lowering costs, including hidden ones.
- Network virtualization is a method of combining the available resources in a network by splitting up the available bandwidth into channels, each of which is independent from the others, and each of which can be assigned (or reassigned) to a particular server or device in real time. The idea is that virtualization disguises the true complexity of the network by separating it into manageable parts, much like your partitioned hard drive makes it easier to manage your files.
- Storage virtualization is the pooling of physical storage from multiple network storage devices into what appears to be a single storage device that is managed from a central console. Storage virtualization is commonly used in storage area networks (SANs). Server virtualization is the masking of server resources (including the number and identity of individual physical servers, processors, and operating systems) from server users. The intention is to spare the user from having to understand and manage complicated details of server resources while increasing resource sharing and utilization and maintaining the capacity to expand later.
- A snapshot is a virtualized copy that offers the capability to preserve the state of the virtual machine so you can return to the same state repeatedly.
- Snapshots provide a change log for the virtual disk and are used to restore a VM to a particular point in time when a failure or system error occurs. There is a source copy, (aka gold copy, source copy, dsource, etc.) that are unchanged blocks between all virtual clones. Only changed blocks are written to disk. The source is a source and can be refreshed daily, multiple times per day or more.
- Along with the hardware!
- This interface is for a storage or server admin, but not a dba or developer/tester.
- Go through how copies can be made, but not virtualized Go through then how a cli without a UI, can make it difficult to manage all those clones and that’s not CDM and may have nothing again, to do with virtualized, takes up space, which Is what cloud loves.

- The ability to identify data anomalies and inconsistencies during testing is essential in measuring the overall quality of the application. The most efficient way to achieve this goal is by employing an automated capability for comparing the baseline test data against results from successive test runs—speed and accuracy are essential. Automating these comparisons helps save time and identify problems that might otherwise go undetected.
- Article 29 makes it unlawful in EMEA to not just encrypt, but to mask data in non production systems and when handling data outside of secure environments. HIPAA protects medical information PCI protects payment information, via the internet, inside companies and in the public eye. PII protects personably identify information between systems, (big brother) for demographics and information collections SOX protects investor information
- If the ssn is the reference key, then the numbers should be masked identically across the objects to ensure integrity is maintained.
- What does this have to do with virtualization? The ability to patch or upgrade once and then refresh or clone with the environment already complete- not having to patch and upgrade, allowing for a single step to refresh and complete these tasks offers incredible time savings. No more complex cloning with scripts, manual steps requiring human intervention. An ability to migrate from one cloud to another without significant challenges or downtime.
