CloudWays 2018 - 4th International Workshop on Cloud Migration and Architecture (CloudWays 2018)

Cloud computing has recently been the focus of attention in computing both as academic research and industrial initiatives (Armbrust et al., 2010). Major IT companies and start-ups envision cloud computing as i) an economic strategy to meet business objectives cost effectively and ii) remain competitive by exploiting technical resources efficiently (Buyya et al., 2009) (Andrikopoulos et al., 2012). From a business point of view, organizations can benefit from the pay-per-use model offered by cloud services rather than an upfront purchase of costly and over-provisioned infrastructure (Tran et al., 2011). From a technological perspective, the scalability, interoperability, and efficient (de-)allocation of resources through cloud services can enable a smooth execution of organizational operations (Khajeh-Hosseini et al., 2012). Given the potential benefits of cloudification, an increasing number of organizational business-critical applications – so-called legacy systems – are being migrated to cloud environments. Regardless of the benefits of cloudification, many organizations still rely on legacy software systems developed over the lifetime of an organization using traditional development methods. In spite of the maintainability issues, (on-premise) legacy systems are still crucial as they support core business processes that cannot simply be replaced. Therefore, migrating legacy systems towards cloud-based platform allows organizations to leverage their existing systems deployed (over publically available resources) as scalable cloud services.
In recent years, research on legacy on-premise application migration to cloud has gained a significant momentum with innovative theories and practical solutions being proposed and investigated by both academia (Jamshidi, Ahmad & Pahl, 2013) and industry (Laszewski & Nauduri, 2011). More recently, migration patterns for microservices have appeared (Balalaie et al., 2016).
