9 What is S ervice O riented Architecture (S O A)? Any Architecture consists of C omponents and their Interrelationships; for S O A: C omponents S ervice P rovider (or the S ervice) S ervice R equestor (or C lient) D is covery Agency (or R egistry) Interrelationships P ublish Find Interact (by far, the mos t important) 9

10 S O A Technology C omponents The two main technology components are: Web S ervices S tack E nabling the I nte ra c t interrelationship in our diagram Web S ervices R egistry E nabling the P ublis h interrelationship in our diagram E nabling the Find interrelationship in our diagram Note: As BM C is not in the Web S ervices infras tructure business, we partner with other software companies and O pen S ource entities for these components. 10

11 S O A Technology C andidate Technologies for S O A include: Web S ervices C O R BA DCE D oes S O A equate to Web S ervices? No (but ) Are there non-web S ervices alternatives for S O A? Not very many C an we apply S O A principles using more traditional tools (e.g. Java/C + +)? Kinda 11

16 Virtual C omputing B ackground S urprisingly Long His tory (B ack to 1960 s ) R ecent R esurgence What is Virtual C omputing Basically, a S imulation of a M achine running on an another M achine Advances in Hardware make running Virtual M achines more feas ible 16

17 Advantages of Virtualization Bus iness Advantages of Virtualization include: C onsolidation of IT hardware as sets M aximization of under-utilized IT hardware res ources R eduction of electrical energy consumption (G reen D ata C enters ) 17

18 C hallenges of Virtualization Virtualization presents a number of challenges in the management space that include: How to know the performance impact of virtualization before you virtualize Anticipating capacity issues and proactively responding to them before service is disrupted R educing the risk of virtualizing R apidly provisioning virtual servers without violating compliance with corporate policy or government regulations E liminating over-provisioning and uncontrolled virtual server sprawl M anaging and ensuring end-user performance of applications running on the virtual infrastructure 18
