NODE.JS ARCHITECTURE AND 12 BEST PRACTICES FOR NODE.JS Even though only 11 years old, Node.js has emerged to be one of the most popular web development frameworks in the last decade.

Scout collects detailed traces of slow requests and, along with our GitHub SET UP A CI/CD PIPELINE WITH CLOUD-NATIVE TOOLS Set up a CI/CD Pipeline with Cloud-Native Tools. The adoption of cloud-based solutions has become increasingly common. The proof for this is evident – according to Gartner, Inc., the worldwide public cloud services market is expected to grow by 6.3% in UNDERSTANDING DISK I/O For random disk access (a database, mail server, file server, etc), you should focus on how many input/output operations can be performed per-second (IOPS). Four primary factors impact IOPS: Multidisk Arrays – More disks in the array mean greater IOPS. If one disk can perform 150 IOPS, two disks can perform 300 IOPS. ASYNC JAVASCRIPT: HOW TO CONVERT A FUTURES API TO ASYNC Javascript is a funny language. It claims to be (and very much is) a single-threaded language (i.e., it executes statements in order, one at a time, one after another, in a synchronous fashion). WHICH RUBY APP SERVER IS RIGHT FOR YOU? Puma. There's a reason Puma is the default app server for newly generated Rails apps and on Heroku today: it's easy to configure and mostly "just works" out-of-the-box. It makes a lot of sense to start with Puma and evaluate Passenger as your app grows and needs more advanced features and configuration options. SERVERLESS VS. CONTAINERS: KEY DIFFERENCES EXPLAINED Serverless computing runs applications on-demand in response to a certain event or trigger, saving you the trouble of starting and managing application servers. Containers are a lightweight virtualization technology that wraps source code together with application dependencies, allowing easy portability and consistency. BUILDING DOCKER CONTAINERS FOR OUR RAILS APPS The next step is to build our custom image that we defined in the Dockerfile, we can do that like this: $ docker-compose build. Now we have an image for our web application, we need to prepare our database (inside the container). $ docker-compose run web rake db:create $docker
UNDERSTANDING LINUX CPU LOAD This is on a dual-core CPU, so we've got lots of headroom. I won't even think about it until load gets and stays above 1.7 or so. Now, what about those three numbers? 0.65 is the average over the last minute, 0.42 is the average over the last five minutes, and 0.36 isToggle navigation
