THE PERFECT STORM

• The rise of microservice architectures

• Existing approaches don’t scale with large networks of services

• The issue is compounded with polyglot environments

• Kubernetes provides easy mechanisms to inject sidecars into application deployments

OPEN QUESTIONS

12

• Will service meshes coexist with traditional API management platforms?

• How will service meshes support traditional needs of IT organizations, like infosec audits and compliance regulations?

• Are there other platform services that may be pushed down to the service mesh?
