Cybertec PostgreSQL Administration and Performance Tuning




PostgreSQL is the world's most advanced open-source database, which means no strange licence restrictions, unexpected costs, or lengthy deployment times. That's why companies such as Netflix, Uber and Instagram all run PostgreSQL. Now you can learn to install, administer, secure and manage your PostgreSQL database with this comprehensive course.

This course covers all major topics related to PostgreSQL. In addition to basic administrative tasks, we deal with performance tuning, monitoring, replication and other important topics.

During the workshop, you will learn first-hand what to pay attention to and how to achieve your goals. You will receive a broad technical foundation from which to expertly manage your database.

Please note that this course needs a minimum of 6 delegates to schedule a course.

Add me to the waiting list

Should you need this course urgently, the following options are available:

  1. Pay for 6 delegates (whether you have them or not) and we will schedule the course as soon as possible.
  2. If you have fewer delegates and cannot pay for 6, we can negotiate a shortened course where some of the time will be spent in blended learning - watching videos and doing tutorials and exercises with some contact time with the trainer. We would want to discuss what your core needs are so that we cover those aspects. You need to have paid for 3 delegates at least.
