Linux Web Operations LiveLessonsguides system administrators, developers, and other Linux professionals through the layers of technology underlying modern web applications. The videos discuss the relationship between web and application servers, load balancers, and databases and introduce configuration management, monitoring, containers, cryptography, and DNS.
In Linux Web Operations LiveLessons, Ben Whaley covers the architecture underlying a modern web stack. Based upon a simple example Python web application hosted in the AWS cloud, each lesson begins with general principles and uses command line examples to reinforce the concepts. Since the web is composed of a huge array of languages and platforms, the tutorials teach the viewer how to think about designing web applications for scalability more than deeply understanding a single technology. The videos cover web, application, and database servers; DNS records and servers; exchanging confidential and authenticated messages using cryptography; Ansible for orchestration and configuration management; working with APIs; and running applications in Docker containers.
Learn How To
- Design web applications for high availability
- Interact with APIs and debug problems with HTTP
- Configure Apache and Nginx web servers
- Extend Nginx with Lua scripts
- Configure master and slave DNS
- Update DNS dynamically
- Configure an HAProxy Load Balancer
- Configure MySQL master/slave replication
- Run applications in Docker containers
- Configure applications automatically using Ansible
- Use SSH, OpenSSL, and GPG to provide data integrity and confidentiality
Lesson 1, “Web Applications,” reviews the common layers in a web application software stack. The lesson covers the role of load balancers, web and application servers, databases, and the underlying systems environment. An example application on a hosted cloud environment is demonstrated using curl to interact with HTTP.
Lesson 2, “Databases,” shows how to set up MySQL to serve as a persistence store for the example application. Viewers learn how to use a script to perform automatic backup to S3 cloud storage and configure replication. They also see how to access a redis key-value store from the command line.
Lesson 3, “Web Servers and Load Balancers,” explores the Apache and nginx web servers and uses haproxy as a load balancer. Viewers learn about Lua as a powerful enhancement for nginx.
Lesson 4, “DNS,” reviews DNS fundamentals covering the most common record types. Viewers learn how to configure a master/slave BIND server for the example.com domain and then restrict the daemon to a chroot jail. Finally, viewers see how to use TSIG to perform dynamic updates and secure zone transfers.
Lesson 5, “Monitoring,” walks viewers through how to decide on the best approach to monitoring the example application. Then, viewers see how to install and configure collectd to gather data from hosts. Next, they see how to send the collected data to Graphite, a django application for storing and querying data. Finally, they see how to use Nagios to set up checks and alerts.
Lesson 6, “Configuration Management,” discusses the purpose of configuration management and orchestration. Viewers learn about Ansible plays and playbooks and how to control hosts by role with Ansible.
Lesson 7, “Cryptography,” covers what to consider about the various forms of cryptography before applying it while using OpenSSH. Viewers then see how to use the OpenSSL command line tools to create a certificate authority and an SSL certificate. They also learn how to use GPG to encrypt and sign files.
Lesson 8, “Containers,” covers the concept of containers and how they fit in the application environment. The lesson focuses on running and building containers with Docker and Dockerfiles.
