Introduction • In mid-August 2012, one of the biggest Oil company in Arabic Gulf region has encounter attacks. • This attack directly affected the internal networks and damaged around 30,000 computers.
• During this disaster, the affected company face interruptions to their IT services and disrupt the communication with other companies for three days. • In this reason, we need to find an effective solution to avoid any disaster that will affect the IT services operation.

BC/DR Business Continuity • Business continuity (BC) describes the processes and procedures an organization puts in place to ensure that essential functions can continue during and after a disaster
Disaster Recovery • Disaster recovery (DR) describes how an organization is to deal with potential disasters
4
Why need the BC/DR? •
Protection of Data (Backup)
•
Protection of Systems Environment – –
•
5
Applications, configurations, state Capacity of operations
Policies and Procedures –
Maintenance & testing
–
Fail over / fail back
–
Security & privacy
Key DR Concepts •
Recovery Time Objective (RTO): – The
maximum acceptable time to recover the system after a disaster.
•
Recovery Point Objective (RPO): – The
maximum acceptable data loss in terms of time prior to a disaster (minutes, hours, days).

Intro in the Cloud Cloud computing is a technology based on Internet system that provides remote data centers to manage data and applications.
In short: “Cloud Computing is the transformation of IT from a
product to a service�

Cloud Models Hybrid Clouds
Deployment Models
Service Models
Private Cloud Cloud Computing with company resources
Software as a Service (SaaS) Using provider’s applications over a network
9
Public Cloud Cloud Computing with globally shared resources
Platform as a Service (PaaS) Deploy customercreated applications to a cloud.
Infrastructure as a Service (IaaS) Rent processing, storage, network capacity and other fundamental computing resources.
Cloud Characteristics Common Characteristics: Massive Scale
Flexible Computing
Homogeneity
Geographic Distribution
Virtualization
Service Orientation
Low Cost Software
Advanced Security
Essential Characteristics: On Demand Self-Service

Intro DR in the Cloud
12
•
Cloud utilizing virtualization technologies environment makes the IT services recover easily by using virtual server which allow to move the services to new server when the disaster occur.
•
Cloud environment provides ideal solution for data backup, data management, and data recovery in the event of disasters.
•
It provides fast recovery and multi-site availability of the software system at very minimal cost.
Type of DR in the Cloud Do-It-Yourself: Configure and manage own DR solution using public Cloud resources.
Disaster Recovery-as-a-Service: Prepackaged pay-as-you-go recovery services to the Cloud with specified RPO & RTO SLAs Cloud-to-Cloud Disaster Recovery: Failover from one Cloud environment to another

DR-as-a-Service (DRaaS) Advantages
15
•
Fixed per-gigabyte cost
•
off-site Cloud based storage
•
Scale up or down your demand based on your needs.
•
Service provider handles the hardware maintenance and backups
•
Protect whole workloads, not jest data
•
Replicate to the cloud, recover and run in the cloud
•
Live restore back to repaired data center
Cloud Based Workload Recovery The benefits of DRaaS at a fraction of the price Offsite Replication

High: • Disaster Recovery site purchase / lease • Redundant hardware • Software licenses • Setup & monitoring
Fixed monthly price
Maintenance
Hardware upgrades, maintenance contracts
None
Flexibility
New workloads need to wait for hardware orders (or keep extra idle hardware)
Scale up or down on demand
