The second phase involves migrating the traffic over to the new systems in a manner that mitigates the risk of incidents while continually monitoring and confirming that we are meeting crucial metrics tracked at multiple levels. This approach has a handful of benefits. We will examine these alternatives in the upcoming sections.

This allows the app to query a list of “paths” in each HTTP request, and get specially formatted JSON (jsonGraph) that we use to cache the data and hydrate the UI. To prepare ourselves for a big change in the tech stack of our endpoint, we decided to track metrics around the time taken to respond to queries.

Instead, focus on understanding what the workloads exercise to help us determine how to best use them to aid our performance assessment. For the network, we can use Iperf to assess the network bandwidth between the client and the database server to ensure it will be enough to meet our peak requirement. 4.22 %usr 38.40 0.42 %sys 9.52

This becomes really important for cache solutions like Redis™. AWS Security Groups and Azure Network Security Groups allow you to lock down access to your servers through advanced virtual firewalls. At ScaleGrid we recommend you deploy your clusters on private VPC subnets so that your database is not routable from the internet.

Unfortunately, this topic is more of an art than a science, given that there is really no foolproof algorithm or approach that can tell you exactly where you might hit a bottleneck with server performance. Global memory caches are static in size as they are defined solely by the configuration of the database itself.

Site performance is potentially the most important metric. Having a slow site might leave you on page 452 of search results, regardless of any other metric. With all of this in mind, I thought improving the speed of my own version of a slow site would be a fun exercise. Compressing, minifying and caching assets.

Most monitoring tools for migrations, development, and operations focus on collecting and aggregating the three pillars of observability— metrics, traces, and logs. Using a data-driven approach to size Azure resources, Dynatrace OneAgent captures host metrics out-of-the-box to assess CPU, memory, and network utilization on a VM host.
