2 G-Clud Service Definitin Slutin Architecture fr Clud Service 1. SERVICE OVERVIEW 6pint6 is an innvative IT cnsultancy that delivers architecture and technlgy services with subject matter expertise in Slutin Architecture. The 6pint6 Slutin Architecture fr Clud Service prvides a standards-based apprach fr slutin architecture definitin (including SOA and EDA styles) and system design. Our architects are specialists in using viewpints and Agile mdelling techniques fr clud deliveries based n IaaS, PaaS, SaaS and c-lcated platfrm architecture definitin in bth private and public sectrs. Our aim is t ensure yur business gals and yur slutin architecture is aligned t prvide maximum return n investment (ROI). The service supprts the planning, transitin, delivery and peratin f clud-based services. 2. SERVICE DESCRIPTION The 6pint6 Slutin Architecture fr Clud Service prvides architecture definitin fr specific prjects and systems. In each case, 6pint6 will: Ensure that the scpe, cntext and cnstraints are dcumented and accepted. Identify, engage and enfranchise key stakehlders Facilitate the making f system-level decisins, ensuring that they are made n the basis f the best infrmatin and are aligned with stakehlder needs Capture and interpret input frm technical and dmain specialists Define and dcument the system structure and frm Define and dcument strategies, standards and guidelines t direct the build and deplyment f the system Ensure that the architecture meets the system quality attributes Help ensure that agreed upn architectural principles and standards are applied t the finished system r prduct Ensure that the architecture meets the clud first apprach t systems delivery. The 6pint6 apprach t slutin architecture definitin encmpasses the fllwing areas: Scpe, Cncerns, Principles and Cnstraints Clarify and cnfirm the fundamental business gals and drivers Define the scpe f the system under cnsideratin, including functinal areas, external interfaces, data t be migrated and systems t be decmmissined Define architectural principles, supprted by ratinales and implicatins with traceability back t business gals and frward t architectural decisins Define the imprtant technlgy cnstraints, such as mandated platfrms and rganisatinal standards Functinal Viewpint Definitin Define the system's runtime functinal elements and their respnsibilities, interfaces, and primary interactins. This includes: Functinal capabilities. External interfaces. Internal structure. Cmmercial In Cnfidence Page 2 f 2 6pint6 Limited Versin: 0.1

3 G-Clud Service Definitin Slutin Architecture fr Clud Service Design style & philsphy Infrmatin Viewpint Definitin Define the way that the architecture stres, manipulates, manages, and distributes infrmatin. This includes: Infrmatin structure and cntent Infrmatin flw Data wnership Timeliness, latency, and age References and mappings Transactin management and recvery Data quality Data vlumes Archives and data retentin Regulatin Cncurrency Viewpint Definitin Define the cncurrency structure f the system, mapping functinal elements t cncurrency units t clearly identify the parts f the system that can execute cncurrently, shwing hw this is crdinated and cntrlled. This includes: Task structure Mapping f functinal elements t tasks Inter-prcess cmmunicatin State management Synchrnizatin and integrity Start-up and shutdwn Task failure Re-entrancy Develpment Viewpint Definitin Define the architecture that supprts the sftware develpment prcess. This includes: Mdule rganisatin Cmmn prcessing Standardisatin f design Standardisatin f testing Instrumentatin Cdeline rganisatin Deplyment Viewpint Definitin Definitin f clud based architecture deplyments n which t deply cludcmputing services, including digital service integratin and security architecture. Define the envirnment int which the system will be deplyed, including the dependencies the system has n its runtime envirnment. This includes: Types f hardware required Specificatin and quantity f hardware required Third-party sftware requirements Technlgy cmpatibility Cmmercial In Cnfidence Page 3 f 3 6pint6 Limited Versin: 0.1

4 G-Clud Service Definitin Slutin Architecture fr Clud Service Netwrk requirements Netwrk capacity required Physical cnstraints Operatinal Viewpint Definitin Define hw the system will be perated, administered, and supprted when it is running in its prductin envirnment deplyed t the clud. This includes: Installatin and upgrade Functinal migratin Data migratin Operatinal mnitring and cntrl Cnfiguratin management Perfrmance mnitring Supprt Backup and restre Crss Cutting System Qualities Define, fr each viewpint, hw key system qualities are addressed. This includes the fllwing categries: Accessibility Availability and Resilience Extensibility Perfrmance and Scalability Lcatin Regulatry Security Usability 3. SERVICE BENEFITS The advantages that result frm wrking with an expert, niche cnsultancy such as 6pint6 t define an elegant slutin architecture include the fllwing: Addresses system qualities key aspects f yur system (e.g. perfrmance, security, availability and resilience) are thught thrugh and designed fr Drives debate and cnsensus by using viewpints, the system can be cmmunicated effectively t all stakehlders. This enables pen debate and drives justificatin f design Supprts the planning prcess - the prcess f defining a clud based slutin architecture supprts task planning, impact analysis, scheduling, transitin planning, cst analysis, risk management and skills identificatin Enfrces standards and style prevent deviatin frm best practices and standards whilst enfrcing an architectural style Prvides a platfrm & framewrk fr re-use identify, create and prmte the use f reusable assets Addresses risk early ur slutin architecture definitin prcess will fcus n the highest risk and architecturally significant scenaris first Cmmercial In Cnfidence Page 4 f 4 6pint6 Limited Versin: 0.1
