Complex SSL/TLS certificate management across multiple microservices
6/10 MediumManaging SSL/TLS configurations becomes increasingly complex when multiple microservices require separate certificates. DNS synchronization issues across cloud platforms (AWS, Azure) make it difficult to automate certificate issuance and renewal with Let's Encrypt.

Automating certificate renewal using tools like Let's Encrypt's Certbot helps, but integrating this into existing infrastructure—especially in distributed systems or microservices—can be error-prone. Additionally, handling certificate revocation requires careful coordination with CAs. With a validity period of a mere three months, public TLS certificates will require renewals not once but four times a year!
When multiple microservices are used, each requiring a separate certificate, configuring SSL/TLS becomes a complex task... DNS synchronization issues can arise, making it difficult to automate the issuance and renewal of Let's Encrypt certificates.
