The Importance of Access Logs in Performance Issue Analysis

Aggregated on: Mon Jan 03 2022 23:04:31 GMT+0000 (Coordinated Universal Time)

An access log is generated by the web server to log the details about the request that it has processed. It logs status code, response time, URL, protocol, size, client IP address, etc., about the request. Load Balancers will have similar log files created to log the request details. While doing any performance analysis, these logs play an important role. It is being neglected most of the time due to lack of awareness and the usage of APM tools abstracts it from the users by allowing them to focus visually on coarse-grained data instead of fine-grained data. Most people are aware of the application server log but many of them are not aware of the web server/load balancer access log. Most of the time, this log will not be striking in the mind of a person who investigates the problem. Access logs are available for the below servers while the format for each of them varies:

Deploying a Scala API on OpenShift With OpenShift Pipelines

Aggregated on: Mon Jan 03 2022 21:04:31 GMT+0000 (Coordinated Universal Time)

I recently took a course on Scala Basics. To further my knowledge, I decided to deploy a simple API on OpenShift using the Pipelines feature and build it using the Scala build tool(not Maven, as there are plenty of tasks for that). Phase 1 First, we need an app, so as a part of the course, I developed a simple expense tracking API that has all the CRUD features and an endpoint to sum all your expenses. I'm going to walk you through the app. In order to build an API, we're going to leverage the use of the Play Framework.

Extracting Data From Very Large XML Files With X-definition

Aggregated on: Mon Jan 03 2022 17:04:31 GMT+0000 (Coordinated Universal Time)

X-definition is an open-source Java API that can be used to extract data from XML files regardless of their size. It will not compel the Java Virtual Machine to complain that it is out of heap memory, nor does it even require that your Java code step through the parts of your XML in the order of their occurrence until the location of the data you need is reached. It requires little more than a markup model of your XML document, and about 90 to 120 seconds of processing time for each gigabyte of XML data. In this article, we'll download a modest (2.5 GB) file from data.discogs.com and extract data from it using a minimum of code. Our X-definition instructions will amount to the following:

Create Lambda Layers in AWS Lambda

Aggregated on: Mon Jan 03 2022 16:04:31 GMT+0000 (Coordinated Universal Time)

For a while, I struggled when it came to making layers for my functions. I used to download them locally, zip them, upload them into S3 when their sizes were big, and then create a version. This process takes a long time, and chances are high that you will make a defective layer when you’re using Windows or Mac because of some layers that compile binaries when you download them. I wrote an article back in 2019 on how to do that with the help of Docker, and it still gets read, which triggers the need to create a new, simple, and extremely fast way to use this amazing feature: Lambda Layers.

How to Do UUID as Primary Keys the Right Way

Aggregated on: Mon Jan 03 2022 15:34:31 GMT+0000 (Coordinated Universal Time)

Why Do We Need Technical IDs in the First Place? Any properly designed relational database table owns a Primary Key (PK) allowing you to uniquely and stably identify each record. Even if the primary key can be composite (built of several columns), it is a widespread good practice to dedicate a special column (often named id or id_<table name>) to this end. This special column is used to technically identify records and can be used as foreign keys in relations. NOTE: Do not confuse technical (also named "surrogate") keys with function keys. The most important tables (so-called entities in domain-driven design) may contain an alternate human-readable ID column (like the customer ID "G2F6D"). In this article, we will focus only on technical PKs. They should only be processed and readable by machines, not humans.

Deploy an Application for Azure Container Registry

Aggregated on: Mon Jan 03 2022 13:04:31 GMT+0000 (Coordinated Universal Time)

Overview Docker Container and Image Introduction to Docker Images Docker is a tool that makes it easier to create, deploy, and run applications by using a containerization approach. These containers are lightweight and take less time to start than traditional servers. These containers also increase performance and lower cost, while offering proper resource management. Another benefit to using Docker is that you no longer need to pre-allocate RAM to each container. Docker Container and Docker Image A Docker container is a virtualized runtime environment used in application development. As mentioned before in the definition of Docker, with Docker, we are able to create, run and deploy applications that are isolated from the underlying hardware. A Docker container can use just one machine, share its kernel and virtualize the OS to run more isolated processes. So, Docker containers are lightweight. A Docker image is like a snapshot in other types of VM environments. It is a record of a Docker container at a specific point in time. Docker images are also immutable. While they can’t be changed, they can be duplicated, shared, or deleted. The feature is useful for testing new software or configurations because whatever happens, the image remains unchanged.

Raising the Bar on Security by Purging Credentials From the Cloud

Aggregated on: Sun Jan 02 2022 01:34:30 GMT+0000 (Coordinated Universal Time)

The Cloud is ubiquitous: any company looking to ramp up quickly will provision its compute, networking, and storage with its preferred cloud provider, and get started rolling out their products. That makes total sense from a business perspective. The Cloud has simplified development and automation exponentially over the years, and emerging tech such as AI and IoT will only accelerate this. However, the catch is that the very same foundational architectures which drive the Cloud’s efficiency, flexibility, and cost benefits ultimately also are its weakest links from a security perspective. The result is the daily march of headlines we all read about: ever larger and deeper breaches of data and systems.

Creating 5,000 background threads in my ASP.NET Web app

Aggregated on: Sat Jan 01 2022 13:49:30 GMT+0000 (Coordinated Universal Time)

I once saw a guy speaking about multi threaded programming, and he asked his audience how many of the people amongst had audience had created multiple threads, at which point half the room lifted their arms. Then he asked how many had used dozens of threads running simultaneously, at which point 25% of the room kept their arms up. When he reached the question "how many have created millions of concurrently executed threads" the speaker was the only person left with his arm raised. The reasons for this of course, is because the idea of creating millions of concurrently executed background threads is simply ridiculous to even imagine. However with Hyperlambda, at least in theory, this is actually quite easily achieved. To understand how this is possible, realise that multi threading is just a state machine, allowing you to perform context switches, at the CPU level, with an interrupt scheduling work for each individual thread.

If you have a website for consumer products, you must know that some challenges exist only with these websites; one such challenge is ensuring that the functionalities work expectedly across browsers and devices. Browsers interpret things differently; hence you have to ensure consistency in the appearance (UI/UX) and functionalities of the website/web application across different browsers. This makes cross-browser testing extremely important as it lets you compare the functionalities and design of a website on multiple browsers, devices, and platforms (operating systems). To fast-track the process of browser compatibility testing, developers should use automated browser testing.

Java: Creating Terabyte Sized Queues with Low-Latency

Contextual Design With Google Actions

Aggregated on: Thu Dec 30 2021 14:34:28 GMT+0000 (Coordinated Universal Time)

One of the most complex tasks while designing a conversation is to create natural interactions with our users. However, there is one process called a contextual design that helps us to create these natural conversations. With the contextual design, you can design your conversation depending on the current situation of our users. For example, if the user is a first-timer using our Google Action, we will tell him/her a different welcome message than if he/she access it for the second time. Another example is the following one: if the user is from one City, we will provide information related to that city accessing geoinformation. Contextual design is one of the keys of Conversational AI.

Improving Development Velocity Using Ephemeral Environments

Aggregated on: Wed Dec 29 2021 21:49:28 GMT+0000 (Coordinated Universal Time)

Velocity is a measurement of how many story points a software development team can finish within a sprint (usually one or two weeks). These points are set by the software development team when they review a ticket and estimate how complex the ticket is. When a team measures this output over a period of time, generally they have a consistent amount of story points they can deliver in a sprint and their velocity is known. Improving developer velocity is directly correlated with performance. McKinsey published an article in April 2020, where they cite that companies in the top 25% on their Developer Velocity Index grow up to twice as fast as companies in their same industries. Intuitively, this makes sense since delivering more allows the development team to learn through iterating and improving.

Stopping Cybersecurity Threats: Why Databases Matter

Aggregated on: Wed Dec 29 2021 21:19:28 GMT+0000 (Coordinated Universal Time)

From intrusion detection to threat analysis to endpoint security, the effectiveness of cybersecurity efforts often boils down to how much data can be processed in real-time with the most advanced algorithms and models. Many factors are obviously involved in stopping cybersecurity threats effectively. However, the databases responsible for processing the billions or trillions of events per day (from millions of endpoints) play a particularly crucial role. High throughput and low latency directly correlate with better insights as well as more threats discovered and mitigated in near real-time. Cybersecurity data-intensive systems are incredibly complex: many span 4+ data centers with database clusters exceeding 1000 nodes and petabytes of heterogeneous data under active management.
