Where does Microsoft fit in?
And let’s not forget about Microsoft. Microsoft has teams in both engineering and field sales that focus on legacy and mainframe modernization. They can offer deep technical guidance on topics such as application migration and integration, data migration, and security. They publish guides and reference architectures to provide consolidated best practices and guidelines.
Here are some resources they have published, which can get you started:
