Aggregated on: Thu Feb 09 2023 19:14:37 GMT+0000 (Coordinated Universal Time)

Modern applications allow us to get connected to the world like never before. However, how is this structure so effective in providing a robust connection between different applications and data sharing between different devices? API (Application Programming Interface) allows developers to build complex features and expose application functionalities as resources. The purpose of an API is to communicate between the client and server. This includes the processes of data transfers, data security, and distribution to different networks and third-party applications. The beauty of APIs is that anyone can access information and features that would otherwise be unobtainable without the need to provide any custom code or integrations.

Introduction to Kubernetes Event-Driven Auto-Scaling (KEDA)

Aggregated on: Thu Feb 09 2023 15:14:37 GMT+0000 (Coordinated Universal Time)

Manual scaling is slowly becoming a thing of the past. Currently, autoscaling is the norm, and organizations that deploy into Kubernetes clusters get built-in autoscaling features like HPA (Horizontal Pod Autoscaling) and VPA (Vertical Pod Autoscaling). But these solutions have limitations. For example, it's difficult for HPA to scale back the number of pods to zero or (de)scale pods based on metrics other than memory or CPU usage. As a result, KEDA (Kubernetes Event-Driven Autoscaling) was introduced to address some of these challenges in autoscaling K8s workloads. In this blog, we will delve into KEDA and discuss the following points: What is KEDA?KEDA architecture and componentsKEDA installation and demoIntegrate KEDA in CI/CD pipelines What Is KEDA? KEDA is a lightweight, open-source Kubernetes event-driven autoscaler that DevOps, SRE, and Ops teams use to scale pods horizontally based on external events or triggers. KEDA helps to extend the capability of native Kubernetes autoscaling solutions, which rely on standard resource metrics such as CPU or memory. You can deploy KEDA into a Kubernetes cluster and manage the scaling of pods using custom resource definitions (CRDs).

Ensuring Predictable Performance in Distributed Systems

Aggregated on: Thu Feb 09 2023 13:44:37 GMT+0000 (Coordinated Universal Time)

Latency spikes can be a frustrating reality for many organizations, especially regarding tail percentiles. It's not uncommon to see unexplained spikes in latency, especially when there's no deliberate focus on predictability. Consider a scenario where a web service must render a personalized web page. To provide a good user experience, ensuring low latency for 90% to 95% of requests is necessary. However, the page's content may require dozens or even hundreds of sub-requests from various components, each with its own variance and randomness. While each component may have low latency in 99% of cases, it might not be enough to guarantee consistent end-user latency. This highlights the importance of having the right Service Layer Objectives (SLOs) for each component to ensure overall system performance.

Test Data Compliance: How to Rewrite Your Organization’s DNA

Aggregated on: Thu Feb 09 2023 01:59:37 GMT+0000 (Coordinated Universal Time)

“We mustn’t use live data for testing.” This is the reason why most organizations start to look at superficial solutions to certain challenges that are ingrained in their DNA. For years, this aversion has driven the way that organizations have changed their “best” practices, struggling to wean themselves off deep-set habits. These organizations often start with low-hanging fruit and create a capability to replace live data with either masked/obfuscated data or synthetic alternatives. They then believe that’s “job done!” It isn’t. It doesn’t tackle or even reduce many of the core challenges associated with using production in test, let alone the systemic problems that led the organization to test using production data in the first place.

Why You Should Think About Moving Analytics From Batch To Real-Time

Aggregated on: Wed Feb 08 2023 17:29:37 GMT+0000 (Coordinated Universal Time)

What was once a pipe dream is now a reality: advances in technology over the past decade have allowed businesses to harness the power of real-time data. However, while over 80% of businesses say transforming to a real-time enterprise is critical to meeting customer expectations, only 12% have optimized their processes for real-time customer experiences, according to 451 Research data. Real-time data is not just a nice-to-have, but a must-have for businesses to stay afloat in the “right now” economy. There are still some clear use cases for batch; for example, payroll or billing typically involve processing a large number of transactions on a regular basis. Batch processing allows companies to efficiently process payroll transactions in a single batch rather than processing them individually in real time. However, more companies are switching to real-time in cases where getting and analyzing continuous data really matters.

Cloud security is an ever-evolving challenge, as organizations must consider the security of the cloud provider, the configuration of the services they offer, and the security of their own internal systems that store and access cloud-based data. Organizations must continuously evaluate their cloud security solutions to ensure the integrity and privacy of their data. In this blog post, we will evaluate the current state of cloud security solutions, discussing the five options available and helping organizations understand how to secure the cloud. We will explore the importance of implementing a comprehensive cloud security strategy, as well as the various tools and technologies used to protect cloud-based systems. Finally, we will discuss the various methods organizations can use to continuously monitor and audit their cloud security solutions. 1. Evaluating the Current State of Cloud Security The first step in evaluating the current state of cloud security is to identify the threats and vulnerabilities that exist in the cloud. This includes understanding the different types of threats, such as external threats, malicious actors, misconfigurations, and insider threats. It is also important to understand how these threats can be exploited and the potential impacts on the organization. Additionally, a review of the current security measures in place needs to be conducted to identify any areas of weakness. This evaluation should include a review of the security tools and policies employed by the cloud provider, as well as the security measures implemented by the organization.

With a rapidly changing business landscape, security is one of the biggest challenges for developers and testers in their modern web development cycle. The complexity of building and deploying modern web apps leads to more security vulnerabilities. As per a Cost of Data Breach report by IBM and Ponemon Institute, in 2021, data breach costs rose from USD 3.86 million (average cost in 2019) to USD 4.24 million, which is the highest average cost of this report in seventeen years. Therefore, cybersecurity is becoming increasingly important in the software development lifecycle to ensure user data security and privacy. Wouldn’t it be great if you could develop and test websites and web apps without worrying about security vulnerabilities? Sandboxing is one technique that can help you achieve this. Sandboxing is an approach for securely isolating an application, a web browser, and a piece of code. It prevents malicious or faulty apps from attacking or spying on your web resources and local system.

Data Integration Strategies for Time Series Databases

Aggregated on: Wed Feb 08 2023 01:29:36 GMT+0000 (Coordinated Universal Time)

As digital transformation reaches more industries, the number of data points generated is growing exponentially. As such, data integration strategies to collect such large volumes of data from different sources in varying formats and structures are now a primary concern for data engineering teams. Traditional approaches to data integration, which have largely focused on curating highly structured data into data warehouses, struggle to deal with the volume and heterogeneity of new data sets. Time series data present an additional layer of complexity. By nature, the value of each time series data point diminishes over time as the granularity of the data loses relevance as it gets stale. So it is crucial for teams to carefully plan data integration strategies into time series databases (TSDBs) to ensure that the analysis reflects the trends and situation in near real-time. In this article, we’ll examine some of the most popular approaches to data integration for TSDBs:

Application Mapping: 5 Key Benefits for Software Projects

However, development teams should be mindful of dependencies and seek to minimize their number and complexity for several reasons:

What Are You Missing by Debugging in VS Code?

Aggregated on: Wed Feb 08 2023 00:14:36 GMT+0000 (Coordinated Universal Time)

In the first chapter of my debugging book, I discuss IDE debugging. In that chapter, I mostly talk about IntelliJ/IDEA. People often ask me why I didn’t write as much about VS Code…The reason is that there isn’t much to write about. Its debugger is simpler for better and for worse. It isn’t as powerful as other IDEs. I created the following video that covers the content of this post: This isn’t a slam against VS Code or against Microsoft. Visual Studio has one of the most powerful debuggers around. But, Visual Studio Code doesn’t have a lot of the features from Visual Studio or other IDEs. I think this is intentional. I think this is a user experience-driven decision in which they removed features to simplify usability. One thing VS Code did well was exposing the log point (tracepoint) feature, so it is more discoverable to the casual developer. That’s pretty great and wouldn’t have been practical if the IDE had all the salient features.

10 Most Popular Frameworks for Building Restful APIs

As with many engineering problems, there are many ways to build RESTful APIs. Most of the time, when building RESTful APIs, engineers prefer to use frameworks. API frameworks provide an excellent platform for building APIs with most of the components necessary straight out of the box. In this post, we will explore the 10 most popular REST API frameworks for building web APIs. These frameworks span multiple languages and varying levels of complexity and customization. First, let’s dig into some key factors in deciding which framework to begin building with. How To Pick an API Framework The first factor in choosing an API framework is usually deciding which language you want to work in. For many projects, depending on the organization you work with or your experience, choices may be limited. The usual recommendation is to go with a language you are already familiar with since learning a new language and a new framework can lead to less-than-optimal implementations. If you’re already familiar with the language, your main focus can be on understanding the framework and building efficiently.

Pipes And Filters Pattern

Aggregated on: Tue Feb 07 2023 20:29:36 GMT+0000 (Coordinated Universal Time)

Applications today collect an infinite amount of data. Many applications need to transform this data before applying any meaningful business logic. Tackling this complex data or a similar processor-intensive task without a thought-through strategy can have a high-performance impact. This article introduces a scalability pattern – pipes and filters – that promotes reusability and is appropriate for such scenarios. Problem Context Consider a scenario where incoming data triggers a sequence of processing steps, where each step brings data closer to the desired output state. The origin of data is referred to as a data source. Examples of data sources could be home IoT devices, a video feed from roadside cameras, or continuous inventory updates from warehouses. The processing steps during the transformation usually execute a specific operation and are referred to as filters. These processing steps are independent and do not have a side effect; i.e., running a step does not depend on any other steps. Each filtering step reads the data, performs a transforming operation based on local data, and produces an output. Once the data has gone through the filters, it reaches its final processed stage where it is consumed, referred to as data sink.

Software development is about cultivating differences in points of view. One of the reasons different roles exist, like product owners, designers, developers, testers, DevOps, and project managers, is to have different points of view during any life cycle. It could be a project life cycle, a product life cycle, a software development life cycle, a software testing life cycle, etc. A product owner will be business oriented. It's all about what we release and its value to the customer. A developer is more implementation driven. It's all about how to implement our features in code. A tester's point of view usually includes technical aspects and business aspects. It's all about constructively critiquing the product and giving valuable feedback to stakeholders. One way to cultivate differences in points of view is to use pairing activities. Pair programming and pair testing are two of the most popular. This article focuses on pair testing, and I will share experiences on how teams have used pair testing to their advantage.

When it comes to designing a cloud-native data system, there's no particular hosting infrastructure, programming language, or design pattern that you should use. Cloud-native systems are available in various sizes and shapes. However, it is true that most of them follow the same cloud-native design principles. Let's take a look at the cloud-native architecture, the design principles you should keep in mind, and the features that make up a good cloud-native platform. Cloud-Native Architecture A cloud-native architecture is essentially a design pattern for apps built for the cloud. While there's no specific way of implementing this kind of architecture or a pre-defined cloud-native design, the most common approach is to break up the application into several microservices and let each microservice handle a different kind of function. Each microservice is then maintained by a small team and is typically deployed as a container.

DevOps has brought the topic of an organizational culture firmly to the table. While culture was always an element of Agile and Lean, the research into DevOps has shown it's just as important as the more technical capabilities. The DevOps structural equation model has several elements related to people and culture, so it's clear that human issues are an important part of the DevOps picture.
