An exploration of the architectural challenges within government and how the Ministry of Justice is introducing true digital transformation by tackling the underlying problems within the system. Over the last couple of years the UK Government has delivered the first wave of Digital Services but they have been hampered by integrations with legacy systems locked away inside walled gardens and immutable monoliths. Microservice architecture offers both a compelling alternative and an achievable plan to slay these lumbering giants by slicing them up into smaller systems which do one thing well, have proportionate security and are highly connected over less trusted networks. This talk will explore the far-reaching consequences of adopting microservice architecture in government, particularly focusing on real examples inside Criminal Justice.
