Describing Distributed Systems

IN THIS COURSE

• 1.  Course Overview
  1m 21s
  FREE ACCESS
• 2.  Working with Distributed Systems
  4m 54s
  In this video, you'll learn more about distributed systems. These are systems with multiple components residing on different machines that all communicate and coordinate with each other to provide a service. But from the perspective of an end user, it may appear as a single system. A common example is a website that relies on a backend database to provide or capture data. FREE ACCESS
• 3.  Types of Distributed Systems
  3m 35s
  In this video, you'll learn more about the four main types of distributed systems in terms of architecture. You'll discover that the most commonly used is the Client-server model. This is because data in one form or another is stored on a server, which is then accessed by a client. Other common architectures include the three-tier model and the n-tier model. FREE ACCESS
• 4.  Benefits of Monitoring
  3m 43s
  In this video, you'll learn the benefits of monitoring your business or organization as a whole. You'll discover that monitoring your business translates into identifying where to focus your attention or determine where changes are necessary. This begins with identifying long-term trends. FREE ACCESS
• 5.  Importance of Monitoring Distributed Systems
  2m 56s
  In this video, you'll learn more about the importance of monitoring a distributed system. You'll begin by noting how it can help analyze trends over the longer term. For example, if you consider something like a database, you can note its initial size and keep track of how much it grows over various timeframes. Other topics include alerting and dashboards.

• 6.  Whitebox vs. Blackbox Monitoring
  2m 51s
  FREE ACCESS
• 7.  Monitoring Dashboards
  3m 45s
  In this video, you'll learn more about monitoring dashboards. These are commonly used by anyone in a monitoring position to provide centralized access to the data that's most relevant to the user. For anything that needs to be monitored, there is some data that's more relevant than other data. FREE ACCESS
• 8.  Events, Alerts, and Incidents
  2m 47s
  In this video, you'll learn more about events, alerts, and incidents. You'll learn there are differences between these three terms. An event is characterized by some kind of an observed change to that which you would consider to be normal. This can apply to many different aspects of any organization including system changes, environmental changes, workflow changes, process changes, or user changes. FREE ACCESS
• 9.  Retrospective Analysis
  3m 41s
  In this video, you'll learn more about the importance of performing an ad hoc retrospective analysis for instances where problems have occurred. You'll learn that an ad hoc retrospective analysis refers to the fact that sometimes things just go wrong unexpectedly despite our best monitoring and alerting efforts. Something that seemed to be an entirely healthy service can fail at any time. FREE ACCESS
• 10.  Monitoring Best Practices
  2m 57s
  In this video, you'll learn more about general best practices for monitoring distributed systems. You'll learn how to configure meaningful alerts and how to prioritize alerts based on their severity. You'll also discover redundancy in your monitoring solution should be implemented. and discover other best practices such as testing your monitoring and alerting system to ensure it is monitoring in a reliable manner and alerting when appropriate. FREE ACCESS
• 11.  Monitoring Strategies
  5m 36s
  In this video, you'll learn about the factors to consider when designing and implementing an effective monitoring strategy. You'll learn that when dealing with distributed systems, you need to take a broader approach to monitoring. You also need to ensure your monitoring solution takes into consideration the application or service as a whole while still monitoring each system involved. And of course, for each system, you need to go right down to the individual component level. FREE ACCESS
• 12.  Expectations for Monitoring
  3m 2s
  In this video, you'll learn more about setting reasonable expectations for your monitoring solution. You'll discover there's no need to configure your monitoring solution to identify and correct every possible issue. Configure simple rules that detect the most prevalent and common issues. Otherwise, you'll spend too much time on maintaining and configuring the monitoring application itself, rather than what you're monitoring. FREE ACCESS
• 13.  Course Summary
  1m 5s
  In this video, you'll summarize what you've learned in the course. You've examined distributed systems, including the importance of monitoring, monitoring strategies, and monitoring best practices. You also explored distributed systems in general and the different architecture models, the benefits and importance of monitoring, and the differences between white box and black box monitoring, monitoring dashboards.
