To kick things off, I’m going to start by taking a look at Dr Howard’s PhD thesis, ‘Distributed consensus revised’. This is obviously longer than a standard paper, so we’ll break things down over a few days. As the title suggests, the topic in hand is distributed consensus: Single-valued agreement is often overlooked in the literature as already solved or trivial and is seldom considered at length,

A bug that is well described has the capability to reduce the time taken to replicate the defect and resolve it. However, perfect bug describing is a skill overlooked by many organizations. Bugs can cause a delay in the release of an application, and during the testing phase, or when the app is at production, developers tend to overlook bugs that are not properly described.

AWS Fargate is a container-as-a-service offering within AWS Elastic Container Services (ECS) that allows you to run containers at scale without requiring you to manage the infrastructure layer. While the classic EC2 launch type of ECS allows you to install Dynatrace OneAgent on the underlying EC2 instances, the AWS Fargate launch type doesn’t provide access to the underlying infrastructure and thus requires a different approach to monitoring.

Call-only ads are a good way to drive calls to your business directly from ads. Call-only ads are only shown on devices that can make calls, such as smart phones. Over time however, we've found that in some highly competitive markets, the quality score of keywords associated with a call-only campaign can drop below 3/10, restricting their exposure. One way around this is to include call-only ads amongst search ads in a search campaign on Google Ads.

When managing cloud-native applications, it's essential to have end-to-end visibility into what's happening at any given time. This is especially true because of the distributed and dynamic nature of cloud-native apps, which are often deployed using ephemeral technologies like containers and serverless functions. With so much flux and complexity across a cloud-native system, it's important to have robust monitoring and logging in place to control and manage the inevitable chaos.
