Governments in the Asia Pacific region see updating old IT systems as a strategic necessity in order to improve digital public services, boost economic competitiveness, and make the country more resilient. Countries like Australia, Japan, Singapore, and India still use old, monolithic systems that were built for stability instead of scalability or interoperability to run important public services. As more people move to cities and the population grows, people want to engage with and get services from digital-first platforms. However, these old platforms have shown that they have problems with security, flexibility, and performance.
