Consolidation is the answer, right? 4/23/2019 8:28 AM Consolidation is the answer, right? Reduces number of stove pipes, but doesn’t solve them Next application/project adds another stovepipe I think of this as “backwards consolidation” Consolidation doesn’t change thinking The problem with consolidation from an SOI perspective is that it is viewed as a project. Once consolidation is complete, its finished. There is no change in approach for future projects, resulting in more stovepipes. SOI fundamentally changes the thinking from stovepipes and solutions to shared services which applications can consume.

Define Enterprise Consumer Experience 4/23/2019 8:28 AM Define Enterprise Consumer Experience If IT infrastructure is obvious to the business = poor perception of IT IT Infrastructure is not designed around users Seek to improve Enterprise user experience Unified view (network drive, published printers) Single sign-on Location independence/roaming User Consumer experience User experience is one of the key things which, if done correctly, will make the business think of IT as a strategic asset. The moment IT becomes “exposed” to the business (e.g. having to manually map network drives, call helpdesk to add a new printer when roaming), it becomes an overhead: poor perception, and costs productivity At this phase, we’re looking at the enterprise user experience, not consuming service experience. Subscriber experience = graceful failure mode: when service dependency fails, give users a “service currently unavailable” page rather than application error © 2005 Microsoft Corporation.

Plan Forward Consolidation 4/23/2019 8:28 AM Plan Forward Consolidation The future is difficult to predict - what i/o, RAM, CPU will my future application need? Abstract & Standardise Categorise subscribers as High, Medium or Low for Capacity (storage & bandwidth) Load (concurrency / transactions) Performance (responsiveness / user expectations) Availability Result: easier to accommodate new consumers and plan capacity. Implement standard platform (hardware/software) for each of above When you’re defining services in the application architecture domain (SOA) you should be doing this already. © 2005 Microsoft Corporation.

SOI Blockers Culture Technology Security Regulatory & compliance 4/23/2019 8:28 AM SOI Blockers Culture Trust between development & infrastructure Technology Security Regulatory & compliance Aim to centralise these instead of service-orient them Technology: no QOS.

SOI Enablers/facilitators 4/23/2019 8:28 AM SOI Enablers/facilitators Virtualisation is your friend, and your enemy Subscriber isolation, easy to add capacity doesn’t solve all problems: remember virtual hosts still need managing & are lower performance Clustering Cost of resilience reduces with addition of services Virtualisation: some QOS controls isolation (security/regulatory) Clustering: Offering better SLAs for minimal extra cost Lowering operational cost – maintenance easier to perform in service hours © 2005 Microsoft Corporation.

SOI Enablers/facilitators SAN Flexibility; capacity, replication, backup Evaluate on a case-by-case Slower than DAS Some applications don’t support SAN replication/backup

Example: Identity Management Service Define Service “Single directory of users for authentication and access control” Define User Experience Transparency (SSO, location independence, discoverability) Define Consumer Experience (capabilities) LDAP Directory (e.g. AD) Authentication (LDAP Bind, NTLM, Kerberos) Authorisation (Group membership) Auditing (directory access)

Example: Identity Management Service Design Logical Service Capacity Performance Scalability Backup & DR Security Extensibility for Consumers Design Physical Service Server sizes Server locations Capacity: how much storage?

Extensibility Remember “blockers”? Technology (Schema) 4/23/2019 8:28 AM Extensibility Remember “blockers”? Technology (Schema) Regulatory (Forest) Security (Account Policies) Schema: use ADAM as application directory where you can extend the schema. Proxy calls into AD meaning you still take advantage of the directory “service”. Regulatory: split the users across forests (or maybe domains). Establish trusts if possible. Security: split the users across domains © 2005 Microsoft Corporation. All rights reserved. This presentation is for informational purposes only.

SOI Enables Role-Based Management

Service Levels IT Cost Transparency Business can choose service based on business needs and cost IT more closely aligned with the business

Summary SOI is a change of thinking SOI is dependent on Service Management Will result in fewer servers, and better availability/management Enables role-based management SOI is should be adopted gradually
