26 Trends & StrategiesOur solutionsSOA– architecture oriented toward developmentThe Comarch SOA Platform is a solution which implements architecture oriented toward services(SOA – Service Oriented Architecture). It allows the integration of various IT systems and simplifiedmanagement of the whole architecture. Adrian Hajduk, the consultant responsible for implementingthe Comarch SOA Platform in financial institutions, answers questions about the ESB.A situation which often occurs in IT sectors ofbanks is where a change in one system forceschanges in other applications, part of the functionsstop working and they have to be mended.Does making changes in financial institutionsreally have to be so complicated?Adrian Hajduk: Problems connected with compatibilitybetween systems mount up as new programs andapplications are added. The number of protocols thatneed to be handled is increasing. With this, the needto integrate new systems with already existing ones isappearing in large organizations. Clients often resign
Trends & Strategies27to design systems that are based solely on standards, which areused by many companies. Unfortunately every company hasits own communication methods which are usually not compatiblewith the competition’s software. There is space herefor using SOA architecture which allows for the integration ofvarious systems using services which fulfill defined businessfunctions. The services that the ESB offers are visible for systemswhich exchange data between one another with its help.Who and why should think about implementing theSOA architecture?Adrian Hajduk: Companies that own systems which communicatewith each other should think about implementing SOAarchitecture. Systems which communicate with each other withoutthe use of the ESB often use spaghetti-type connections.It is not only difficult to manage them, but at a certain pointthe IT sector loses control over which system sends messagesto which. Problems also come up in integrating new applicationsinto the system. If the client owns a SOA solution, thenall that is required is the adding of new services to the systemor, if there is such a possibility, using existing ones.What are the advantages of implementing theComarch SOA Platform for the IT sector and whatare they for the business sector of the financial institutionin question?Adrian Hajduk: When deciding to use the Comarch SOAsolution the IT sector gains greater control over communicationsbetween systems, as well as the possibility of easier integrationwith new applications. Additionally, thanks to the useof such elements of the platform as the SOA Registry or SOASupervisor, it can catalogue and test services, manage queuesor control the SLA. The business sector gains the possibility toimplement new solutions at a lower cost as well as the certaintythat the services will realize set business functions. It isworth remembering that a good service is one which allowsthe user to find out exactly what it is doing without the needfor extra IT knowledge. For example, the user knows what theservice “pay funds onto the account” is for.implementation. Reports are made duringthe analysis stage, thanks to whichthe most important business processesfor the client are defined. The documentdescribes the existing applications andtechnologies used to create them. Itallows the user to become familiar withthe data model being used. A canonicaldata model as well as a mapping anddata transformation process based on thisdata model. The process of integration followsthe analysis phase which starts withthe most important system. This systemis moved to the ESB first, less importantsystems follow.Which companies have used theComarch solution? Who can benext?Adrian Hajduk: In most cases the solutionis used by financial institutions.Clients who may be interested in theComarch SOA Platform are thereforebanks, insurance companies, capital marketcompanies and service industry companiesor telecoms firms which own a fewsystems, that have to communicate witheach other. Companies thinking aboutimplementing a few new systems in thefuture should also think about its integration;the costs of integrating each systemseparately will most definitely be alot higher.Interview by Grzegorz Pękałafrom implementing a new system due to the problem of integration.Even if the implementation of a new solution is justified,the costs of its integration with the remaining systems can belarger than the forecasted profits. An ideal solution would beHow does Comarch’s proposal stand out compared toother products available on the market?Adrian Hajduk: Comarch’s solution is a complete platformwhich not only consists of software but also includes businessand systems analysis as well as integration. Additionally,every implementation is characterized by an individual clientapproach and division into phases. During the implementationthe client has control over the whole process. Clients ownsystems which can integrate themselves with other systemsusing various methods. If the company acquires a ready-madesolution with imposed methods of integration, then it has alimited possibility of influencing the method of integration.Lets return to the implementation. It usually has amulti-phase course. What exactly does this look like?Adrian Hajduk: Every implementation is made up of a fewphases, including analysis and the correct process of systemAdrian HajdukComarch SAE-mail: Adrian.Hajduk@comarch.comPosition: Business Solutions ManagerSector: Financial Services
