Virtualization is the creation of virtual versions of hardware like servers and storage. The document discusses virtualization trends increasing in cloud adoption and how virtualization can provide savings through cost reduction and optimized resource usage. It also summarizes key aspects of virtualization technology including storage/server virtualization, snapshots, thin cloning, and network virtualization. The document advocates for copy data management and test data management solutions to help deliver test environments quickly while masking sensitive data for compliance.

- 15. 15© 2016 Delphix Corporation How Snapshots Work
- 16. 16© 2016 Delphix Corporation 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. Types of Snapshots

- 31. 31© 2016 Delphix Corporation 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 Requirements 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. Masking in the Picture
- 32. 32© 2016 Delphix Corporation • Virtualization is a large landscape. • 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
- 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.
- One image, many copies, only the header is required to create an backup or restore.
- 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.
