There is an interesting feature of the Bitcoin protocol that doesn't receive the attention we should attribute to it. Bitcoin is able to integrate and have endpoints (in Bitcoin terminology 'wallets' and 'miners') seamlessly talk to each other in a large and dynamic network. Anyone can easily setup a wallet and within minutes will be able to interact with other members of the network. That cannot be taken for granted. Take a typical Enterprise for example at a Telecommunications company. Within their enterprise network you will find a large amounts of disparate sometimes small, often large Application like CRM, Billing which need to talk to each other, for example to exchange customer sales orders.

Search for Enterprise Service Bus or Middleware and you...

This is the second part of a two-part article series. The first part is published at Know the Difference: Reusability vs. Reuse – Part I. In this final chapter, some different approaches on how to promote reuse from a reusable solution will be presented.

This is the second part of a two-part article series. The first part is published at The Rapid Development of Solutions using XP – Part I. This work presents a proposal of using XP for service development in an SOA environment. For this purpose, in this section we go through each SOA principle and present how each XP practice can be used to support that SOA principle. Afterwards, we analyze the SOA complexities and how the XP practices can be used to tackle them. Our goal is to define the guidelines and best practices for creating an effective Service Agile Development approach. In the following subsections, we present how SOA principles can be supported by XP. All stakeholders, including customers, service providers, service consumers and brokers, should understand the Metaphor that will guide the development and the Planning Game. To understand the metaphor, propose to perform several meetings (planning games) among...
