3. Overview of Business Continuity and Disaster Recovery Business continuity planning (BCP) simply put is the planning of how to stay in business in the event of a disaster. Typical disasters fall in the following categories: Local events (i.e. Building fires) Regional events (i.e. Floods) National events (i.e. pandemic illness or terror attacks)

4. Phases of BCP

5. Analysis Phase This is the phase in which BCP requirements are determined. Requirements are determined by doing the following analysis and documentation: Impact analysis – this differentiates what is critical and non-critical functions Recovery Point Objectives (RPO). This is the point in time at which data must be recovered as defined in the BCP. Recovery Time Objective (RTO). This is the duration of time and a service level within which the key systems as defined in the BCP must be restored Threat analysis - documentation of possible threats (i.e. cyber attack or natural disasters) Definition of impact scenarios Recovery requirement documentation – at the end of the analysis phase, a business and technical plan requirements are documented to move on to the next phase which is solution design

6. Solution Design Phase The solution design phase is the phase where the most cost effective disaster recovery solution that meets the requirements from the analysis phase is identified. In general they fall under: the minimum applications and data is needed for the business entity’s to function the time that is acceptable for the applications must be available

7. Implementation Phase The implementation Phase is simply the execution of the elements or solution that was determined during the solution design phase.

8. Testing and organizational acceptance phase This phase is where testing is done to achieve organizational acceptance that the solution satisfies the organization’s recovery requirements. Testing may include: Failover tests from primary site to DR site and vice versa Application testing Users connectivity

9. Maintenance Phase There are 3 periodic tasks that fall under this phase: Information updates (i.e. key personnel) Testing and verification of technical solutions (anti-virus, hardware and data verification) Testing and verification of recovery procedures

10. Disaster Recovery, a subset of the BCP Disaster Recovery is the process, policies and procedures related for recovery or continuation of the technology infrastructure critical to an organization after a natural or human-induced disaster.

11. Data protection Common Startegies for Data protection: Backups (i.e. disk to tape, D2D and/or off-site Backup) Replication of Data off-site, in most cases using SAN based replication. High Availability (HA) systems such Host clustering

12. Overview of Business Continuity and Disaster Recovery

13. Where does VDI fit in? VDI addresses the need for the users or critical users to connect to the companies IT infrastructure in the event of a disaster at the primary location. The 2 most common uses are: To have virtual desktops running at the DR location To have users connect from anywhere provided that the users are able to connect to the internet

14. Brief overview of virtualization

15. Traditional architecture cpu memory NIC HDD

16. Current problems of traditional architecture • Server sprawl, “one application one server model” • Low utilization of server resources • Expensive operational costs • Real estate • Power requirements and cooling • Slow provisioning • Harder to manage

17. What is Virtualization? • Server virtualization–decoupling of software from hardware • Virtual desktop infrastructure

18. Virtualized infrastructure One to one model Multiple operating systems on one Software decoupling

19. Full Enterprise Solution Typical Virtual Infrastructure Core Switching Hosts (ESX, Xen or Hyper-v) on blade system Dedicated switching (FC or iSCSI) Storage array

20. Full Enterprise Solution hosts

21. Benefits of going virtual • Get more out of the hardware • Up to 80% utilization of hardware resources • Reduce hardware requirements by a 10 to 1 ratio • Reduce time to provision servers by up to 70% • Reduce yearly operation costs by 80% and power costs by 50% which roughly amounts to $3,000 of savings per VM
