1. Security Agility Reduced Cost Security Agility Reduced Cost Foundation for an agile IT Infrastructure: Building the ultimate database container with Red Hat Enterprise Linux, MySQL, and Virtualization Jan Mark Holzer jmh@redhat.com Consulting Engineer Emerging Technology Group CTO Office

2. RHEL5 & MySQL Database Appliances / August 15 th 2007 Product features subject to change prior to availability 2 Outline What is virtualization and how can it help Red Hat Enterprise Linux 5 & Virtualization Database Appliances Use Models and Deployments Q&A Red Hat Enterprise Linux

3. RHEL5 & MySQL Database Appliances / August 15 th 2007 Product features subject to change prior to availability 3 Why virtualization ? Its fun. It gets a lot of papers published. Its going to change everything. Eventually. But the customer benefits boil down to just two things…

4. RHEL5 & MySQL Database Appliances / August 15 th 2007 Product features subject to change prior to availability 4 Customer Benefits Virtualization can help to manage cost Virtualization enables distributed, automated system management Virtualization allows resources to be managed as abstract entities Independent of physical instantiation, location – even existence Physical servers host multiple virtual servers Virtual servers are objects that hide underlying complexity Presents a common interface and architecture Simplifies OS and system maintenance Hardware abstraction Virtual resources can be allocated and managed dynamically Enables more efficient use of existing resources Manage such things as cost, QoS, power,floor space, cooling and security Enhances scalability while controlling costs Virtualization is the fundamental enabling technology for utility computing and utility services, both of which will reduce costs

5. RHEL5 & MySQL Database Appliances / August 15 th 2007 Product features subject to change prior to availability 5 Customer Benefits Virtualization can help to manage risk Virtual servers run in secure compartments Isolation is comparable to separate physical servers Failures, even user and kernel errors, cannot propagate to other virtual servers Individual applications can be mapped to separate virtual servers Enhances security and separation Avoids application incompatibility problems Separation of virtual and physical resources facilitates availability Transparent hot-swap component replacement and upgrades Live virtual server migration for load management and maintenance Low-cost redundancy Virtualization provides a risk buffer for capacity planning Under-provisioning to reduce expenses Over-provisioning to ensure adequate capacity Dynamic resource management can mitigate these risks

6. RHEL5 & MySQL Database Appliances / August 15 th 2007 Product features subject to change prior to availability 6 Example: Data Center Dilemma Data center has physical constraints Fixed sized, fixed power, fixed cooling, etc Often physical constraints are cost prohibitive to change Data centers have excess capacity Volume servers (Intel ISS) 10-15% utilized, mid / high 30-40% (>4 socket) Customers comfortable with single application server One application per OS instance – optimal unit of management, control, etc. Application stacking to consolidate on a single OS viewed as higher risk and often more expensive Need a new service, deploy a new server / storage (ie VM warehouse model) Dilemma Can no longer afford current paradigm Cant afford the $10 million server or storage controller that translates into a new data center or expansion Cant afford continual increase in number of administrators or cost / time to deploy new services Cant afford power and thermal management e.g. Annual electric bill for Googles 200K servers greater than cost of all server hardware

7. RHEL5 & MySQL Database Appliances / August 15 th 2007 Product features subject to change prior to availability 7 Example: Server & Storage Virtualization Multiple Views One or more applications per view One OS per view Multiple OS versions per server Enable transparent migration of services between hardware instances – blades, enclosures, etc. Benefits Increased hardware utilization Avoid the $10 million dilemma Reduced time to deploy new services Dont need to purchase new server / storage to deliver Use views to validate service on existing hardware while maintaining complete isolation and protection Reduced cost Fewer servers to buy / manage Lower software licensing Per core rather than unit of work / value delivered Few administrators Decouple hardware evolution from software No longer legacy software constrained Virtualization provides legacy view Change customer control point Virtual and physical management infrastructure drive customer purchase decisions Motivated to upgrade to virtualization-capable hardware and software De-motivated to migrate to competitive offerings Those that establish beachhead will be more difficult to displace

8. RHEL5 & MySQL Database Appliances / August 15 th 2007 Product features subject to change prior to availability 8 Multiplex one machine into different Virtual Machines VMs; allows running different isolated guest Operating Systems with different applications on same physical hardware. Allows a Guest OS to run under control of a supervising master program that is called: Hypervisor or Virtual Machine Monitor (VMM). Hypervisor / VMM Functionality: Virtualizes System Resources Provides Scheduling of host/guests Intra-guest communication Common grounding 'Host' also often referred as 'dom0' and/or HyperVisor 'Guest' also known as 'domU' Hypervisor/VMM Hardware What is Virtualization?
