When will I have access to the lectures and assignments?

To access the course materials, assignments and to earn a Certificate, you will need to purchase the Certificate experience when you enroll in a course. You can try a Free Trial instead, or apply for Financial Aid. The course may offer 'Full Course, No Certificate' instead. This option lets you see all course materials, submit required assessments, and get a final grade. This also means that you will not be able to purchase a Certificate experience.

What will I get if I subscribe to this Specialization?

When you enroll in the course, you get access to all of the courses in the Specialization, and you earn a certificate when you complete the work. Your electronic Certificate will be added to your Accomplishments page - from there, you can print your Certificate or add it to your LinkedIn profile.

Is financial aid available?

Yes. In select learning programs, you can apply for financial aid or a scholarship if you can’t afford the enrollment fee. If fin aid or scholarship is available for your learning program selection, you’ll find a link to apply on the description page.

What you'll learn

High availability needs proactive replication planning; reacting after failure is too late to protect data and continuity.
Physical replication slots ensure reliable streaming by preventing WAL loss and maintaining data flow during outages.
Monitoring replication lag is vital; keeping it under 5 seconds enables near real-time access on read replicas.
Database replication is not just backup strategy but a core architecture decision that enables both disaster recovery & read scaling capabilities.
