Monitoring and Performance Wrap Up - September 2020

Hi! I'm Helen, one of your friendly mods looking after the #monitoring and #performance tags.

At the end of each month, I'll be showcasing some of the great posts, projects, and insights from the Dev community.


To get us started Tim from the Angular team shows us how to improve performance with prefetching. This can be used to make your application feel faster. As long as you have a cache to persist the data, you can use this technique to improve the user experience.



Next, Mark from the Bearer.sh team lists the most common and valuable metrics to monitor when relying on third-party API integrations and web services. Accurate monitoring and alerting can provide you with the data to decide where to focus your engineering efforts



Rajan then gives us some tips on optimising the performance of Lambdas. Although Lambda is a managed service and it automatically scales, it's the client's responsibility to correctly use the service. By using these optimisations you can lower your Lambda bill.



Next, we have a post from Vinicius from PHP Brazil all about asynchronous programming in PHP. Check it out for great tips to improve performance and manage costly I/O operations.



Py returns to the wrap up for another month with a post on Android objects and the tools we can use to analyse memory. Reading the Android sources is fun! Even when you have no idea how C++ works.



Next, we have Kunal and a post on Prometheus. An open-source monitoring and alerting tool. It was originally built by SoundCloud and now it is 100% open-source as a Cloud Native Computing Foundation graduated project. It has become highly popular in monitoring container and microservice environments.



To end this month's wrap up we have a post on currying in JavaScript from Anders who also returns to the wrap up for a second month. Check it out for use cases and if it's a good choice for your next project.




That's all for this month! For more, check out the #monitoring and #performance tags.
